			<content:encoded><![CDATA[&nbsp;<br />
The short answer to the question posed in the title is "yes" but there are many caveats. One of them is that it depends on what level you are teaching. In my opinion, the value of exposing science students to the primary scientific literature (papers) increases as students progress from first year to the year they graduate. Students in their final year of a science program will gain a lot from being exposed correctly to the scientific literature but students in introductory course will hardly benefit at all&mdash;and may, in fact, be harmed if it takes time away from learning basic principles and concepts.<br />
<br />
It is important to teach critical thinking and it's important to focus education on basic principles and concepts. Most of the basic principles and concepts in a discipline have been developed over several decades. The work that led to those ideas is (usually) in the primary scientific literature but you can't learn the concept by just reading a few key papers. Evolution is a good example but so is our understanding of how cells generate energy from proton gradients, how enzymes work, and how the information in messenger RNA gets translated into proteins.<br />
<br />
I find it helpful to remind myself from time to time that the vast majority of the students I teach will never <u>be</u> scientists and many of them aren't really interested in how to <u>do</u> scientific experiments. They will become average citizens in all kinds of careers that have nothing to do with the basic sciences. Our goal is to make them scientifically literate so they will understand why evolution is true, why homeopathy is bunkum, why they should vaccinate their children, and why humans are behind global climate change. I don't think we can achieve that goal by focusing on the primary scientific literature, especially in the early years of undergraduate education.<br />
<br />
<a href="http://www.teachcreate.org/index.php?pageID=163">C.R.E.A.T.E.</a> is a education project funded by the United States National Science Foundation (Grant No. 1021443). It's goal is "transform understanding of science" by using the primary scientific literature as a teaching tool. Here's how they describe their approach ...<br />
<blockquote class="brown"><i>The C.R.E.A.T.E. (Consider, Read, Elucidate the hypotheses, Analyze and interpret the data, and Think of the next Experiment) method is a new teaching approach that uses intensive analysis of primary literature to demystify and humanize research science for undergraduates. Our goal is to use the real language of science—the journal article—as an inroad to understanding “who does science, how, and why?” At the same time, we wish to help students (1) experience authentic processes of science, in particular discussion/debate about experimental data and their interpretation (including ‘grey areas’), (2) recognize the creativity and open-ended nature of research, and (3) see the diversity of people who undertake research careers (i.e. not just the genius/geeks of popular culture). As a complement to teaching based on textbooks, which tend to oversimplify the research process, C.R.E.A.T.E. teaching focuses on on authentic published work--peer reviewed journal articles—with students reading either series of papers produced sequentially from individual labs or series of papers from different labs focused on a single line of research.<br />
<br />
By reading/analyzing a set of papers published in series from a single lab, students experience the evolution of research projects over a period of years. Using newly-developed C.R.E.A.T.E. pedagogical tools, that encourage multiple approaches to the material (concept mapping, sketching, visualization, transformation of data, creative experimental design) students gain deep understanding of the methods (and biological content/principles) that underlie each individual experiment of the paper. In class, we emphasize scientific thinking--focusing on understanding both why and how each part of the study was done, by examining the hypotheses underlying each aspect of the study, and analyzing/discussing the data represented in each figure and table. Students learn to interpret complex data, draw conclusions, debate interpretations, and re-represent data (e.g. represent tabled data in graphic form) to aid understanding. Content knowledge is reviewed as students consider the principles underlying the techniques used, as well as the overall context of the scientific question being addressed (e.g. a module focused on regeneration would likely include review multiple aspects of cell division, cell differentiation, gene expression and stem cells, drawing on information students learned in other classes and helping them to apply it in a real-world research situation). C.R.E.A.T.E. students thus learn a variety of transferable learning skills that can be applied to complex scientific reading they do in the future. Students design their own proposed followup experiments at several points in the semester, and debate each other’s proposed studies in a classroom exercise modeled on activities of bona fide scientific grant panels. Such discussions reveal the research process to be openended, with multiple branch points or possible “next directions to go;” thus much less linear and predictable than many students expect. Late in the process, students generate a short list of questions for paper authors that are sent as an email survey to each author (not simply the PI). Responses from multiple authors provide unique behind-the-scenes insight into “the people behind the papers,” humanizing the research experience and showing researchers to be complex individuals much like the students themselves.</i></blockquote>Here's an example based on <a href="http://www.teachcreate.org/p13.php?pageID=188">Pattern formation during regeneration in planaria</a>.<br />
<br />
This is an approach that views experiment as the primary focus of science whereas I tend to see science as a much broader way of knowing. The C.R.E.A.T.E. approach to undergraduate education emphasizes the doing of science rather than the understanding of the results and how they fit into a bigger picture. It probably does a good job of looking at "trees" but not so good a job when it comes to seeing the "forest."<br />
<br />
I don't know the correct balance between teaching principles, ideas, and concepts and teaching the experimental approach taken by actual research scientists in their day-to-day activities. There's no question that lab courses are extremely important but I'm quite skeptical about bringing the study of experimental techniques into the lecture courses if it take time away from the conceptual understanding of the discipline.    <br />

He used to be a professor in my department here at the University of Toronto. I miss him, and wish he were still here.<br />
<br />
Chris blogs at <i>BioImplement</i> and he has just started a new series of posts on <a href="http://bioimplement.blogspot.com/2012/01/new-series-on-complexity-and-evolution.html?spref=fb">Complexity and Evolution</a>. His goal is to explain how human design can inform us about evolution. The idea is to refute the arguments of Intelligent Design Creationists who treat intelligent design as something mystical that's1 beyond naturalism.<br />
<br />
Here's how Chris explains what's coming ...<br />
<blockquote class="brown"><i>The thread connecting these examples of human design is that each one is an analogy to biological evolution, from which evolution may be better understood by laypersons. Now by posting new examples like this, I realize that they may all be stolen by the “intelligent design” (ID) creationists to argue against evolution. My view on ID follows that most clearly expressed in the 2005 court judgment from the Pennsylvania Kitzmiller v. Dover case: “The overwhelming evidence at trial established that ID is a religious view, a mere re-labeling of creationism, and not a scientific theory.” Of course a few scientists have written in defense of evolution and against ID nonsense in the classroom, the most strident of whom is Richard Dawkins. I now add my voice in support, as in his final interview with Dawkins, Christopher Hitchens lamented “It’s the shame of your colleagues that they don’t form ranks and say, ‘Listen, we’re going to defend our colleagues from these appalling and obfuscating elements.’”<br />
<br />
So into the breach, I add my voice with some new arguments, after this small bit of throat-clearing. I will try to avoid being derivative as I come armed with my own capacity for inquiry, insight, and argument. My examples will show how ID concepts force the gerrymandering of human design history, and surround it with mystical borders to make their claims. The individual steps in human design are small, slow and absolutely require the intellectual imprinting of lessons by trial and error. Students who are led to think falsely about human design, or any complexity as having mystical origins are harmed by the diminishment of their own aspirations of creativity. We all need to understand how small steps and tools lead to human creativity and any object of complexity. I will reveal these small steps and show, where I can, the failures that led to success. </i></blockquote>I know Chris and I can assure you that his upcoming posts will be provocative and informative.    <br />

<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-5YJcUh3M-o4/TwcVvrsV4KI/AAAAAAAAMBM/2euV3A_U3Kc/s1600/tmp.jpg" imageanchor="1" style="clear:right; float:right; margin-left:1em; margin-bottom:1em"><img border="0" height="300" width="400" src="http://1.bp.blogspot.com/-5YJcUh3M-o4/TwcVvrsV4KI/AAAAAAAAMBM/2euV3A_U3Kc/s400/tmp.jpg" /></a></div>Last month the science magazines and websites were all talking about a paper by Zhang et al. (2012) published in <i>Cell Research</i>. These workers discovered plant micoRNAs in the serum of mice and humans. The microRNAs seem to come from ingested rice. Presumably the micoRNAs are taken up in the intestine and secreted into the blood in small vesicles. The concentration of the major rice miRNAs in serum is about 10 fM or 10&times;10<sup>-15</sup> moles per liter.<sup>1</sup> <br />
<br />
The authors have shown that microRNA MI168a binds to the mRNA of low-density lipoprotein receptor adapter protein 1, inhibiting translation. This leads to the idea that ingested plant microRNAs can regulate the expression of human genes. That's the story that generated the most press [<a href="http://blogs.discovermagazine.com/80beats/2011/09/21/what-you-eat-affects-your-genes-rna-from-rice-can-survive-digestion-and-alter-gene-expression/">What You Eat Affects Your Genes: RNA from Rice Can Survive Digestion and Alter Gene Expression</a>, <a href="http://www.scientificamerican.com/article.cfm?id=vitamins-minerals-and-microrna">Food We Eat Might Control Our Genes</a>].<br />
<br />
This is one of those findings where the explanation doesn't make a lot of sense but the data seem sound. It seems very unlikely that small plant RNAs could survive the processing and digestion of rice or any other food and even less likely that they would find their way into the bloodstream where they could play a role in regulating mammalian gene expression. I think I'll wait for confirmation. <br />
<br />
It's a shame that none of the articles in the popular press expressed any sort of skepticism. That's one of the problems with science journalism. How do you convey the idea that all scientific results are preliminary until they have been confirmed by others?     <br />
<br />
<hr width="200"/><font size="2"><blockquote>1. That concentration is far below the concentration where effective binding can occur but the idea seems to be that the micoRNAs are contained in small vesicles that subsequently fuse with liver cells and deliver the rice microRNA to the cytoplasm where it can inhibit translation of specific mammalian RNAs. It's difficult to see how one could get an effective concentration of plant microRNA in one of these mammalian cells.   <br />

			<content:encoded><![CDATA[ <br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-QeGj_F9unio/TvDBNxaGYGI/AAAAAAAAL_s/Z9ze_G4DDD8/s1600/tmp.jpg" imageanchor="1" style="clear:right; float:right; margin-left:1em; margin-bottom:1em"><img border="0" height="267" width="400" src="http://4.bp.blogspot.com/-QeGj_F9unio/TvDBNxaGYGI/AAAAAAAAL_s/Z9ze_G4DDD8/s400/tmp.jpg"/></a></div><br />
The earliest fossil examples of most animal classes and phyla appear in the fossil record at about the same time in the Cambrian (about 530 million year as ago (Ma)). This period of apparent rapid divergence is referred to as the &quot;Cambrian Explosion.&quot; <br />
<br />
It seemed unlikely that this disparity could have evolved in just a few million years so many scientists have been searching for fossil antecedents in the early Cambrian and Ediacaran (635-541 Ma). Many trace fossils have been found in the past few decades, indicating that the fossil animals of the Cambrian were preceded by small wormlike creatures. <br />
<br />
The other approach has been sequence analysis. One can construct molecular phylogenies by comparing the sequences of genes in modern extant organisms. This approach has been highly successful over the past fifty years so that we now know a great deal about the relationship of the various animal phyla. The correspondence between the old morphological taxonomy and molecular evolution is the most powerful evidence we have that evolution explains the history of life [see <a href="http://evolutionwiki.org/wiki/Nested_Hierarchy">Twin Nested Hierarchies</a>].   <br />
<br />
The problem with sequence comparisons has always been getting accurate dates using the molecular clock. It is hard to get an accurate date when dealing with events that occurred 500 million years ago because there aren&#39;t very many calibration points. An accurate calibration point is a known time when two lineages diverge. <br />
<br />
If there really was a rapid divergence in the Cambrian then one would expect the molecular tree to show this. But it never has. The molecular phylogeny shows that chordates diverged from invertebrates at least one hundred million years before their fossils appear in the Cambrian. Similarly other phyla and classes of animals have their origin long before the Cambrian, according to the molecular clock.<br />
<br />
A recent paper in <i>Science</i> extends this comparison by calculating more a more accurate molecular phylogeny using seven housekeeping genes from 118 different species (Erwin et al. 2011). The result is shown in Figure 1 of the paper: &quot;The origin and diversification of animals as inferred from the geologic and genetic fossil records.&quot; (Click on the figure to embiggen.) <br />

The answer is clearly "no" as they demonstrate time and time again.<br />
<br />
This time it's an anonymous posting on the premier IDC website, <i>Evolution News & Views</i> [<a href="http://www.evolutionnews.org/2011/12/long_non-coding054291.html">Long Non-coding RNA Punches Another Hole in "Junk Genome" Myth</a>]. The anonymous poster links to a recent paper in <i>Genes & Development</i> that shows a function for a particular <a href="http://en.wikipedia.org/wiki/Long_non-coding_RNA">long non-coding (lnc) RNA</a>. The paper implies that many of these lncRNAs (up to 400) are expressed in mouse erythroid cells. <br />
<br />
Regulatory RNA have been known and studied for at least four decades and various lncRNAs have been characterized over the past twenty years. The IDiot at <i>Evolution News & Views</i> seems to think that this is a new discovery proving that there's no junk in our genome. The facts are quite different. <br />
<br />
As I pointed out in my review of <i>The Myth of Junk DNA</i>, the amount of the genome devoted to producing lncRNAs is about 0.1% [<a href="http://sandwalk.blogspot.com/2011/05/junk-jonathan-part-6-3.html">Junk & Jonathan: Part 6—Chapter 3</a>]. So, not only have we known about regulatory RNAs for many years, we also know that their genes don't account for very much of the genome, I figure it can't be more than 2% even when you include all of the most optimistic estimates of regulatory RNAs [see <a href="http://sandwalk.blogspot.com/2011/05/whats-in-your-genome.html">What's in Your Genome?</a>].<br />
<br />
But the ignorance of the IDiots is much more profound than just being incapable of calculating percentages. The latest posting reveals the depth of their ignorance.      <br />
<blockquote class="yellow"><i>These findings have two important implications. First, non-coding regions of the genome were assumed to be leftover evolutionary relics that no longer play a functional role. The assumption was not due to extensive studies of non-coding regions of the genome, but rather to a commitment to what is known as the central dogma of molecular biology: DNA is transcribed into RNA and RNA is translated into amino acids to make proteins. This was considered the primary purpose of DNA. The non-coding regions were assumed to have no function, and were dismissed as the natural consequence of genetic "junk" accumulating over time. This paper is one among an accumulating corpus of papers discussing new and interesting functions of the non-coding regions of the genome. (See The Myth of Junk DNA by Jonathan Wells for a history of "junk" DNA and additional references describing the function of so-called "junk" DNA. See here for a discussion on the regulatory role of introns.)</i></blockquote>There was never a time in the past fifty years when knowledgeable biochemists and molecular biologists thought that all non-coding DNA was nonfunctional junk. This was never an assumption of the Central Dogma of Molecular Biology which states that "... once (sequential) information has passed into protein it cannot get out again" [<a href="http://sandwalk.blogspot.com/2007/01/central-dogma-of-molecular-biology.html">Basic Concepts: The Central Dogma of Molecular Biology</a>]. There are many scientists who have misconceptions about the Central Dogma  [<a href="http://sandwalk.blogspot.com/2011/05/central-dogma-strawman.html">The Central Dogma Strawman</a>] but the IDiots go one step farther by misunderstanding the misconception!<br />
<br />
We've known about functions in non-coding DNA since the early 1960s as anyone who has ever glanced at a textbook would know. It's hard to tell whether the IDiots are just butt-ignorant of basic science or whether they are lying. This is an especially tricky problem when the silly strawman argument is popularized by Jonathan Wells because he's supposed to know the science [<a href="http://sandwalk.blogspot.com/2011/03/junk-jonathan-part-1-history-correct.html">Junk & Jonathan: Part 1—Getting the History Correct</a>] [<a href="http://sandwalk.blogspot.com/2011/04/junk-jonathan-part-2-what-did.html">Junk & Jonathan: Part 2— What Did Biologists Really Say About Junk DNA?</a>]. <br />
<br />
We know that most of our genome is junk because we know a great deal about genomes, genes, biochemistry, molecular biology, and evolution. We know which parts are likely to be functional and which parts are likely to be broken genes and other kinds of junk. We know this because we understand the subject, not because we are covering up our ignorance. <br />
<br />
The IDiots are ignorant of the science and they assume that everyone else is as well. That's a very bad assumption.<br />

The Board of Directors voted on accepting new Associate Members at its December 11th meeting. I have just received a letter from the Board signed by the new (?) Chair, Richard Thain.<br />
<blockquote class ="textbook">Dear Professor Moran,<br />
<br />
On December 11, 2011 one of the many important items on the agenda for the Board od Directors meeting was discussion of the applications for Associate Membership. <br />
<br />
The goal is to have a diverse group of Associate Members which reflects our membership geographically. In order to achieve this, the Board recognizes that we must update our website and post the By-Laws which explain the governance of CFI Canada.  We hope to attract more applications which will then be reviewed before the next CFI Canada AGM in March 2012. <br />
<br />
We felt it was important to approve some of the applications at the December 11th board meeting, so we reviewed and accepted the following five people:<br />
<br />
Iain Martel, Seanna Watson, Brian Eelhart, Craig Irving and Marlowe Filippov. <br />
<br />
The other applications were put under review and will be considered with the next wave of applicants at a future board meeting.  <br />
<br />
The Board of Directors realizes you have made and are continuing to make significant contributions to our success.  We would like to sincerely thank you for your continued support and committment to helping CFI build a better Canada through reason.<br />
<br />
Richard Thain DDS<br />
Chair, Board of Directors<br />
CFI Canada</blockquote>My application was rejected! <br />
<br />
I wish I knew why the Board didn't accept my application but did accept some others. Iain Martel is the Chair of CASS and Seanna Watson is the Director of the Ottawa branch of CFI so I assume that the people filling these positions are a sort of <i>ex officio</i> Associate Members. That makes a lot of sense especially for Iain and Seanne who have devoted so much time and effort to CFI.<br />
<br />
Bryan Eelhart was the  Financial Agent for the Green Party in the riding of <a href="http://trinityspadinagreens.ca/media/bryaneelhartrachelbarney/">Trinity-Spadina (Toronto)</a> during the recent Ontario election. He's a member of the Board of Directors at <a href="http://www.consciencecanada.ca/wp/?p=123">Conscience Canada</a> and he works for <a href="https://ulife.utoronto.ca/organizations/view/id/2532">Science for Peace</a>. Bryan has extensive expertise in website design and implementation.<br />
<br />
<a href="http://ca.linkedin.com/in/craigirving">Craig Irving</a> is a freelance videographer from Toronto. He serves on the Multimedia Committee at Centre for Inquiry Canada. <br />
<br />
Marlowe Filippov lives in Ottawa where she volunteers at the Centre for Inquiry. <s>She's also an expert in websites.</s> She's been helping out with membership problems and advising the National Director on other issues.  <br />
<br />
It appears that <s>three</s> two of the new Associate Members were chosen for their ability to help out with updating the CFI website. <br />
<br />
There are currently three Associate Members who are <a href="http://www.cficanada.ca/about/cfi_canada_advisory_fellows_board_of_directors">CFI Advisory Fellows</a>; Jeff Rosenthal from Toronto, Chris diCarlo from Guelph, and Ethan Clow from Vancouver. It's possible that the Board of Directors felt that only three CFI Canada Advisory Fellows should also be Associate Members, or maybe they felt that having two from the Toronto area was too much and that's why my application was rejected. <br />
<br />
I'll try and find out more about the qualifications required for Associate Membership. It's clear that length of membership in CFI is not important since there are Associate Members who only joined CFI two years ago. I think that active volunteering on administrative tasks is an important criterion so if you are currently helping out in this area you will probably have a good chance of being appointed.<br />
<br />
I'm a little unclear about the criterion of reflecting membership geographically. About half of all CFI Canada members are from the Toronto area but I don't think this means that half of the Associate Members will be from Toronto. I think it means that you're more likely to be chosen as an Associate Member if you are from one of the other centres that isn't already represented. <br />
<br />
I'm not sure what the role of a CFI Canada Advisory Fellows is supposed to be. If we can't be Associate Members then who are we supposed to advise?  :-)<br />
<br />
Post a comment if your application was also rejected. That way we might be able to figure out what the Board of Directors is thinking when it comes to appointing new Associate Members. I'll let the Board know about this posting so they can comment, or at least see your comments.<br />

<br />
Torley hangs out at <i>Uncommon Descent</i> where he tries to defend Intelligent Design Creationism. He didn&#39;t like my recent posting on Irreducible Complexity [<a href="http://sandwalk.blogspot.com/2011/12/barry-arrington-explains-irreducible.html">Barry Arrington Explains Irreducible Complexity</a>] because I accused Barry Arrington of not understanding evolution. You might recall that Arrington began his defense of irreducible complexity by saying, &quot;(1) By definition, evolution can work only in a stepwise fashion wherein each successive step is “selected for” because it has conferred a selective advantage on the organism.&quot;<br />
<br />
This is not how evolution is defined and it&#39;s a particularly bad way to begin because the scientific understanding of many irreducibly complex systems involves the fixation of neutral or even detrimental alleles. Competency in evolution also requires an understanding of redundancy, contingency, and sloppiness. <br />
<br />
Vincent Joseph Torley asks, &quot;<a href="http://www.uncommondescent.com/intelligent-design/will-this-do-professor-moran/">Will this do, Professor Moran?</a>&quot; He starts with ....<br />
<blockquote class="yellow"><i>Let me state up-front that I am a philosopher, not a scientist. However, I believe in arguing rigorously, so I have attempted to state the argument from irreducible complexity in a rigorous fashion.

			<content:encoded><![CDATA[&nbsp;<br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-Sj7XEZEOo40/TuuIO5N6MtI/AAAAAAAAL-8/4zfDkWHnBNY/s1600/tmp.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="292" src="http://3.bp.blogspot.com/-Sj7XEZEOo40/TuuIO5N6MtI/AAAAAAAAL-8/4zfDkWHnBNY/s400/tmp.jpg" width="400" /></a></div>The genome of the two-spotted spider mite, <i>Tetranychus urticae</i> has been sequenced and the results were published in <i>Nature</i> last month (Grbic et al. 2011).<br />
<br />
Spider mites eat plants. They produce silk-like webs and that's why they're called "spider mites". They belong to the class Arachnida, which is the same group that contains spiders. The Arachnids are in the subphylum <a href="http://en.wikipedia.org/wiki/Chelicerata">Chelicerata</a>, a large group of arthropods distantly related to the insects and crustaceans. This is the first genome sequence of a chelicerate and that's why it's important. <br />
<br />
<b>Genome Size</b><br />
<br />
The genome is only 90 Mb in size. It's the smallest arthropod genome that has been sequenced so far. Contrast this size with the human genome at 3,200 Mb or the genome of another tick, <i>Ixodes scapularis</i>, estimated to be 2,100 Mb. (Honeybee = 236 Mb, <i>Drosophila</i> = 140 Mb.) According to Ryan Gregory's <a href="http://www.genomesize.com/statistics.php?stats=arachnids#stats_top">animal genome size database</a> this is the smallest known arachnid genome and the smallest known arthropod genome. <br />
<br />
The authors estimate that there are 18,414 protein-encoding genes in the mite genome. This is about the same number of genes as most insects whose genomes have been sequenced and only slightly less than the number of genes in the human genome. <br />
<br />
About 41% of the mite genome consists of exons (protein-encoding). Recall that less than 2% of our genome encodes proteins and in most insects the exon sequences make up less than 10% of the genome. (Honeybees and <i>Drosophila</i> also have smaller than average genome sizes.) <br />
<br />
<b>Introns</b><br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-2i-sg01stfA/TueOLxFdriI/AAAAAAAAL-U/ApY7eEBpyjA/s1600/tmp.bmp" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="400" src="http://2.bp.blogspot.com/-2i-sg01stfA/TueOLxFdriI/AAAAAAAAL-U/ApY7eEBpyjA/s400/tmp.bmp" width="208" /></a></div>As you might imagine, the mite genome has a lot less junk DNA than other animals. This is partially reflected in the number and size of the introns. The average protein-encoding gene has less than three introns and the ones that are present are a lot smaller than the introns in species with larger genomes.<br />
<br />
The figure on the right is a truncated version of a figure that appears in the supplemental information. It shows that the smallest introns are 40 bp and 70% of all introns are less that 150 bp in length (median = 96 bp). This is close to the smallest possible intron size allowing for slices sites and formation of a loop during splicing.<br />
<br />
<b>Transposons and Repetitive Sequences</b><br />
<br />
Transposons (active and degenerate) make up less than 10% of the <i>T. urticae</i> genome and highly repetitive sequences (microsatellites) are almost absent. (The spider mite chromosomes don't have centromeres.)<br />
<br />
Transposon sequences and highly repetitive sequences are a major component of the junk DNA found in large genomes so their absence in the mite genome is not a surprise.<br />
<br />
<b>Why Is the Mite Genome So Small?</b><br />
<br />
The short answer is, we don't know. The long answer is much more complicated. As Michael Lynch points out (Lynch 2007 p.37), there's a balance between rates of insertion and deletion mutations. In species with small genomes the spontaneous rate of nucleotide deletion exceeds that of insertion so genome sizes shrink over time. <br />
<br />
There may not be a selective advantage to having small or large genomes. It may just be that in some species the repair machinery tends to favor deletions while in closely related species the enzymes don't have this bias. Or maybe large genomes are slightly deleterious but the population size isn't large enough to allow natural selection to act. Some lineages may never have encountered significant bottlenecks so they've maintained a huge population size for millions of years allowing natural selection to operate on slightly deleterious mutations. This leads to smaller genomes.<br />
<br />
Whatever the explanation, the small genome of mites shows us that most of the junk DNA present in other arthropod genomes is dispensable. That's why it's called "junk."<br />

<span class="themeboxleft"><b>THEME</b><br />
<br />
<a href="http://sandwalk.blogspot.com/2008/02/theme-genomes-junk-dna.html">Genomes & Junk DNA</a><br />
</span>Jonathan McLatchie takes on PZ Myers in a spirited attack on junk DNA [<a href="http://www.evolutionnews.org/2011/12/finding_treasur054241.html">Treasure in the Genetic Goldmine: PZ Myers Fails on "Junk DNA"</a>]. The Intelligent Design Creationists are convinced that most of our genome is functional because that's what a good designer would create. They claim that junk DNA is a myth and their "evidence" is selective quotations from the scientific literature. They ignore the big picture, as they so often due.<br />
<br />
I discussed most of the creationist arguments in my review of <a href="http://sandwalk.blogspot.com/2011/10/myth-of-junk-dna-by-jonathan-wells.html"><i>The Myth of Junk DNA</i></a>.<br />
<br />
Jonathan McLatchie analyzes three argument made by PZ Myers in his presentation at Skepticon IV. In that talk PZ said that introns are junk, telomeres are junk, and transposons are junk. I have already stated that I diasgree with PZ on these points [see <a href="http://sandwalk.blogspot.com/2011/12/pz-myers-talks-about-junk-dna.html">PZ Myers Talks About Junk DNA</a>]. Now I want to be clear on why Jonathan McLatchie is wrong.<br />
<ol><li><b>Introns are mostly junk.</b> I think PZ exaggerated a bit when he dismissed <u>all</u> introns as junk. My position is that we should treat introns as functional elements of a gene even though many (but not all) of them could probably be deleted without affecting the survival of the species. Each intron has about 50-80 bp of essential information that's required for proper splicing [<a href="http://sandwalk.blogspot.com/2008/02/junk-in-your-genome-protein-encoding.html">Junk in Your Genome: Protein-Encoding Genes</a>]. The rest of the intron, which can be thousand of base pairs in length, is mostly junk [<a href="http://sandwalk.blogspot.com/2008/02/junk-in-your-genome-intron-size-and.html">Junk in Your Genome: Intron Size and Distribution</a>]. Some introns contain essential gene regulatory regions and some contain essential genes. That does not mean that all intron sequences are functional.</li>
<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-8rkBhXrcrNQ/Tu9xnsnFRDI/AAAAAAAAL_U/w87fpBXwclw/s1600/tmp.bmp" imageanchor="1" style="clear:right; float:right; margin-left:1em; margin-bottom:1em"><img border="0" height="326" width="299" src="http://1.bp.blogspot.com/-8rkBhXrcrNQ/Tu9xnsnFRDI/AAAAAAAAL_U/w87fpBXwclw/s400/tmp.bmp" /></a></div><li><b>Telomeres are not junk.</b> I don't think telomeres are junk [<a href="http://sandwalk.blogspot.com/2008/05/telomeres.html">Telomeres</a>]. They are absolutely required for proper DNA replication. PZ Myers agrees that telomeres (and centromeres) are functional DNA (28 minutes into the talk). Jonathan McLatchie claims that PZ describes telomeres as junk DNA, "Myers departs from the facts, however, when he asserts that these telomeric repetitive elements are non-functional." McLatchie is not telling the truth. </li>
<li><b>Defective Transposons are Junk.</b> PZ Myers talks about transposons as mobile genetic elements and states that transposons make up more than half of our genome. That's all junk according to PZ Myers. My position is that the small number of active transposons are functional selfish genes and the real junk is the defective transposon sequences that make up most of the genome [<a href="http://sandwalk.blogspot.com/2011/09/transposon-insertions-in-human-genome.html">Transposon Insertions in the Human Genome</a>]. Thus, I differ a bit from PZ's position. Jonathan McLatchie, like <a href="http://sandwalk.blogspot.com/2011/08/junk-jonathan-part-9-6.html">Jonathan Wells</a>, argues that because the occasional defective transposon in the odd species has acquired a function, this means that most of the defective transposon sequences (~50% of the genome) are functional. This is nonsense.</li>

You have to identify the molecule (common name only) and describe (briefly) its function. Can you name the precursor?<br />
<br />
Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post <b><u>correct</u></b> answers to avoid embarrassment. This is your last chance to enter the Christmas draw for a free textbook!<br />
<br />
There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.) Every undergraduate who posts a correct answer will have their names entered in a Christmas draw. The winner gets a free autographed copy of my book! (One entry per week. If you post a correct answer every week you will have ten chances to win.)<br />
<br />
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!) <br />
<br />
In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.   <br />
<br />
Winners will have to contact me by email to arrange a lunch date.<br />
<br />
<b>UPDATE:</b> The molecule is <a href="http://en.wikipedia.org/wiki/Thyrotropin-releasing_hormone">thyrotropin-releasing hormone</a>. It's derived from a long precursor protein containing multiple repeats of the tripeptide Glu-His-Pro.<br />
<br />
The winner is Joseph C. Somody.<br />

<a href="http://en.wikipedia.org/wiki/Guillermo_Gonzalez_(astronomer)">Guillermo Gonzalez</a> is a <a href="http://www.discovery.org/p/33">Senior Fellow</a> at the Center for Science and Culture (Discovery Institute).<br />
Douglas Axe, director of <a href="http://en.wikipedia.org/wiki/Biologic_Institute">The Biologic Institute</a>, which is largely funded by the Discovery Institute.<br />

<br />
This is the best they have to offer. It gives you a very good idea of what Intelligent Design Creationism is all about. It's about nothing ... there's not a single mention of what IDC stands for and not a single bit of evidence for the existence of a designer. All you hear is whining about real science (evolution) and conspiracies.<br />
<br />
Here's a quotation from  Berlinski.<br />
<blockquote class="yellow"><i>Nobody else is doing what the Discovery Institute has been able to do, and that is really put an entire scientific establishment on the defensive, forced for the first time to respond to some very significant criticism...</i></blockquote><br />

			<content:encoded><![CDATA[&nbsp;<br />Christopher Hitchens died yesterday and everyone in the atheist community is going to pay tribute in their own special way. For me, the highlight of Hitchen's career was last year's debate with Tony Blair here in Toronto (Nov.  26, 2010). The subject was "Is religion a force for good or ill?"<br />

<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-qJlJlZlEmV4/Ttamm3SVfMI/AAAAAAAAL8c/2quIlnVbBkI/s1600/Centre+for+Inquiry.jpg" imageanchor="1" style="clear:right; float:right; margin-left:1em; margin-bottom:1em"><img border="0" height="85" width="311" src="http://1.bp.blogspot.com/-qJlJlZlEmV4/Ttamm3SVfMI/AAAAAAAAL8c/2quIlnVbBkI/s400/Centre+for+Inquiry.jpg" /></a></div>The Board of Directors of CFI Canada met with a few Associate members last Sunday (Dec. 11, 2011). The purpose of the meeting was to discuss the termination of Justin Trottier as national Executive Director. Ian Bushfield has put together a brief description of the meeting at: <a href="http://canadianatheist.com/2011/12/13/the-continuing-story-at-cfi-canada/">The Continuing Story at CFI Canada</a>. <br />
<br />
The Board of Directors has emailed a statement to interested parties (see below). You can find out who's on the Board of Directors and who's an Associate Member at: <a href="http://sandwalk.blogspot.com/2011/12/whats-happening-at-centre-for-inquiry.html">What's Happening at Centre for Inquiry Canada?</a>.<br />
<br />
It's difficult to know what the Board has in mind with respect to Justin. They have not given him a paying job but they seem to be holding out hope that he might take over when the acting National Executive Director leaves in March 2012.<br />
<br />
According to their statement, the Board is committed to adding new associate members. They say they have made decisions on some of the applications that they have already received. I have not heard from them on the status of my application.<br />
<br />
Meanwhile, the Chair of CFI Edmonton, Brent Kelley, has resigned [<a href="http://canadianatheist.com/wp-content/uploads/2011/12/Resignation-as-Chair-of-CFI-Edmonton.pdf">Resignation as Chair of CFI Edmonton</a>]. <br />
<blockquote class="textbook">On Sunday, December 11, the Associate Members of CFI Canada met in Toronto. This meeting was followed shortly thereafter by a meeting of the board of directors. We, the board, believe it is important to provide you with information about these meetings and the actions and decisions that took place at these meetings.<br />
<br />
The meeting of Associate Members was scheduled pursuant to the by-laws of our organization, that is, it was scheduled after the requisite number of Associate Members requested the meeting. The request for the meeting indicated its purpose was to consider the separation of Justin Trottier from the position of National Executive Director (NED), so that topic was discussed. Justin Trottier, who was present at the meeting, was provided a summary of the concerns of some of the directors and he was provided an opportunity to address those concerns. Some Associate Members also expressed their views, as did some of the Regional Executive Directors who audited the meeting.<br />
<br />
We believe there was a frank and candid discussion of Justin Trottier’s tenure and the circumstances that led to his separation. We also believe this frank, candid exchange of views was of benefit to the organization. <br />
<br />
Shortly after the Associate Members meeting, the board met. One of the issues considered was increasing the number of Associate Members. Among the decisions of the board on this issue were the following:<br />
<ul><li>The board unanimously agreed to invite additional applications to the position of Associate Member, to ensure broader representation of the supporters of CFI Canada in this important class of membership;</li>
<li>Application forms can be obtained from the Interim NED, Michael Payton (mpayton@cficanada.ca), or from Kevin Smith, Secretary for the board;</li>
<li>Because the primary duty of the Associate Members is to elect directors at the organization’s annual meeting, applications will be reviewed carefully, and emphasis will be placed on the applicant’s prior work for and familiarity with the organization, as well as commitment to its mission; </li>
<li>The board concluded, consistent with the by-laws, that Associate Members should be a subset of the general membership and that the number of Associate Members should be kept at a manageable level;</li>
<li>The board resolved to act on applications in a timely manner so that applicants would be informed of their status prior to the March 11 annual meeting; </li>
<li>The board considered and acted on some of the applications it received prior to the December 11 meeting, and accepted applicants will be notified via email. </li>
</ul>The board heard a report on the organization’s finances and the status of the organization from Interim NED Michael Payton. Although the organization has no cash crisis, and has sufficient assets to maintain operations in 2012, it was apparent that the organization needs to make efforts to increase donor support, and the board directed Mr. Payton to undertake fundraising. The Interim NED indicated he needed assistance in his new position to deal with the many tasks which require immediate attention.The board expressed appreciation for Mr. Payton’s willingness to step in quickly and assume the Interim NED position given the sudden departure of the prior NED. The board authorized Mr. Payton to seek volunteer assistance and stated it would consider a request to authorize<br />
hiring of additional staff.<br />
<br />
The board decided the branding initiative would continue, but that it would be put on hold given the current status of the organization. The organization’s first priorities are to ensure stability and reliable management, raise money, and begin to offer regular programming and services again as soon as possible.<br />
<br />
After appropriate motions, the board resolved the following:<br />
<ul><li>No final decision would be made on Justin Trottier’s possible reemployment in any position until the March 11 board meeting. In reaching this decision, the board carefully considered the views that had been offered concerning Mr. Trottier, both pro and con, as well as his record as NED. We also took into account the fact that we agreed to retain our current NED untill March at which time he will<br />
voluntarily step down.</li>
<li>The board would look favorably upon Mr. Trottier’s volunteering of his services to CFI Canada during the period prior to the March 11 board meeting. <br />
Lorne Trottier took no part in the voting on these motions. The motions carried 3-0, with Tom Flynn absent and Kevin Smith abstaining.</li>
</ul>After the board meeting, the board was informed that Justin Trottier would volunteer to assist the organization. CFI Canada welcomes his willingness to volunteer, as it welcomes the willingness of all its volunteers to donate their valuable time and energy to furthering our mission.<br />
<br />
One other item the board discussed at length was the perception that there is a lack of transparency and openness in board deliberations. To that end the board will be doing some renovations to the web site which will include, among other things, the posting of our by laws. We will also make available, the application to become an Associate Member along with the guidelines for applying. We will also have a dedicated email so CFI supporters can directly contact the board, the email directors@cficanada.ca<br />
will be up by starting Thursday Dec 15th.<br />
<br />
The board is committed to using its best efforts to ensuring not only the survival, but the success of CFI Canada and its important mission. We are well aware that many of the decisions we make are bound to be controversial. We cannot please everybody. At the end of the day we have to rely on our judgment. Our service as directors is not perpetual. Associate Members will be able to reelect or remove us at the March 11 meeting. In the meantime, we pledge to you that we will act in good faith, motivated by what we think is best for the organization and its missio<br />
<br />
Thank you for your support. </blockquote><br />

That was one of my first successful experiments as a graduate student (1969). <br />
<br />
This is a complex molecule so I'm not going to insist on the IUPAC name. You can supply a common name as long as it is unambiguous (be careful!).  This time it's not sufficient to just give me the name of the molecule. You also have to briefly explain what it does and where you can find it, including the "species." The functional explanation has to be a biochemical explanation.<br />
<br />
Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post <b><u>correct</u></b> answers to avoid embarrassment.<br />
<br />

If you post a correct answer every week you will have ten chances to win.)<br />
<br />
After today, you have only one more chance to win an autographed book.<br />

Some scientists are&mdash;believe it or not&mdash;actually addressing their main arguments head-on and showing them to be vacuous.    <br />
<br />
The IDiots don't like this because they are used to posting very silly arguments from amateurs on their blogs and then complaining that scientists are only picking the low-hanging fruit and not addressing the true "experts." Truth is, all of the so-called "expert" arguments have been refuted ages ago.<br />
<br />
Here's an example from Barry Arrington who explains the real meaning of irreducible complexity and why it supports intelligent design [<a href="http://www.uncommondescent.com/intelligent-design/denis-alexanders-strawman-just-as-silly/">Denis Alexander’s Strawman Just as Silly</a>].<br />
<blockquote class="yellow"><i>No ID theorist has ever argued that evolution is impossible because complex biochemical systems cannot self assemble “all in one go.”  This is an absurd caricature of the argument from irreducible complexity (IC).  <br />
<br />
The basic logic of IC goes like this:  (1) By definition, evolution can work only in a stepwise fashion wherein each successive step is “selected for” because it has conferred a selective advantage on the organism.  (2) an irreducibly complex system is a system which if one part is removed all function ceases.  (3) by definition, therefore, an irreducibly complex system cannot be produced in a stepwise fashion.  (4) therefore evolution is not capable of producing an irreducibly complex system. <br />
<br />
Starting with this logic the ID proponent argues that certain systems are irreducibly complex and therefore could not have been produced by evolution.  The bacterial flagellum and the blood clotting cascade are classic examples of such systems. </i></blockquote>I have frequently accused Intelligent Design Creationists of not understanding evolution. For example, one of their heroes, Phillip Johnson, clearly thinks that natural selection is a synonym for evolution in spite of the fact that other mechanisms have been known for almost a century [see <a href="http://recursed.blogspot.com/2011/12/this-video-should-be-shown-to-all.html">This Video Should Be Shown to all Biology Students </a> and <a href="http://sandwalk.blogspot.com/2011/12/phillip-johnson-one-of-very-best.html">Phillip Johnson, One of the Very Best Intelligent Design Creationists</a>]. <br />
<br />
Jonathan McLatchie defended his hero by saying [<a href="http://www.evolutionnews.org/2011/12/jeffrey_shallit053841.html">Maligning Phil Johnson, with Lots of Rhetoric but Little Substance</a>] ...<br />
<blockquote class="yellow"><i>This is the type of condescending rhetoric that is so prevalent in anti-ID writings. Does Shallit really think that we haven't heard of processes such as genetic drift and endosymbiosis?</i></blockquote>We look forward to hearing again from Jonathan McLatchie about how IDiots like Barry Arrington understand evolution.<br />
<br />
Arrington's false premise (#1) isn't the only thing wrong with his argument because one can quite easily construct plausible scenarios where each step in constructing an irreducibly complex system confers a selective advantage. All you have to do is postulate that the intermediate selective advantages are not the same as the final purpose of the system.  <br />
<br />
This is all been thoroughly debated over a decade ago. It's just not true that the concept of irreducible complexity has so flummoxed evolutionary biologists that they have abandoned evolution. <br />
<br />
Barry Arrington also takes on one of my comments from somewhere. I don't remember the context but apparently I questioned whether the definition of "information" from computer science and philosophy could be applied to the "information" in DNA sequences. The problem is that, according to Intelligent Design Creationists, if the DNA information is the same as other kinds of information then it has to be created by an agent like some god or some space alien.   <br />
<br />
They don't seem to be troubled by such an explanation because they never ask the obvious question ... where did the information in the designer come from?<sup>1</sup><br />
<br />
Anyway, read Barry's defense of the idea that information in a DNA sequence is the same as other kinds of information that requires a designer [<a href="http://www.uncommondescent.com/intelligent-design/upright-biped-replies-to-dr-moran-on-information/">Upright Biped Replies to Dr. Moran on “Information”</a>].<br />
<br />
[<b>UPDATE</b>: Apparently that last posting was written by someone called "Upright Biped" and Barry Arrington just posted it under his own name on <i>Uncommon Descent</i>.] <br />
<br />
Remember that Barry Arrington is a lawyer from Colorado and one of the regular bloggers on <i>Uncommon Descent</i>. Most IDiots consider him an expert on Intelligent Design Creationism. In other words, this is as good as it gets.<br />

<blockquote class="brown"><i>Atheists deny that God exists. Yet for an atheist to make our ranking of the 50 top atheists in the world—given in ascending order—it is not enough merely to deny that God exists. More is required.<br />
<br />
Certainty. To make our list, someone has to be very sure of him- or herself. No mere agnostics will do. To make the cut, one has to do more than merely question God’s existence or even deny that knowledge of God’s existence is possible.<br />
<br />
Celebrity is another requirement. To make our list, the atheist must have a public identification with atheism and must have made some public impact by challenging religion and/or promoting atheism, either in print or on the Internet. In other words, our ranking is a list of people who are well known because they are atheists, among other things—as opposed to people who are mainly famous for some other reason (like Jodie Foster or Bruce Willis). In a few cases, a person has made the list mainly on the basis of his or her attack on free will and morality—the foundation of the traditional religious view of human beings—so long as the person has also publicly identified as an atheist.</i></blockquote>I know for a fact that some people on the list do not agree with the definition of atheist that the website promotes. <br />
<br />
The ranking seems to be based largely on the production of books about atheism so it's heavily tilted toward philosophers. In fact, the top five are all philosophers. The top scientist, at number 6, is E.O. Wilson.<br />
<br />
I'm surprised that there are philosophers who deny that gods exists as opposed to just not believing in them.<br />
<br />
I'm not a very good atheist 'cause I've never heard of most of the top 50 atheists. <br />

The long answer is, "I don't think anyone else does."<br />
<br />
Here's what I know.<br />
<br />
<b><a href="http://www.cficanada.ca/about/committee_for_the_advancement_of_scientific_skepticism">Committee for the Advancement of Scientific Skepticism</a> (CASS)</b><br />
<blockquote>CASS continues to meet and there are many projects under way. One of the co-directors, Michael Kruse, resigned because he wasn't happy with the direction that CFI was headed. The other co-director, Iain Martel is carrying on.</blockquote><br />
<b>Centre for Inquiry Ontario</b> <br />
<blockquote>Right now this branch doesn't exist as far as I can tell. There's no leader and no volunteers are working.</blockquote><br />
<b>National Executive Director</b><br />
<blockquote>The acting National Executive Director is Michael Payton. He is struggling to get a grip on the organization after the abrupt departure of Derek Pert a few weeks ago. (Derek was forced to resign when the Board of Directors failed to support him.) The former National Executive Director, Justin Trottier, was fired last September.)<br />
<br />
Michael could use a lot of help but there's no room for anyone else in the new office. Don't expect the website to be updated in the near future. Don't expect any memberships to be renewed&mdash;and certainly don't expect to be notified if your expires. Don't even expect any email messages from the head office.<br />
<br />
Michael is leaving for Singapore in a few months and there's nobody who looks like they could step into his job.</blockquote><b><br />
Board of Directors/Associate Members</b><br />
<blockquote>Three members of the Board of Directors resigned two weeks ago (Carol Parlow, Ian McCuaig, and Michael Gardnier). The remaining Canadian members are: Kevin Smith, Lorne Trottier, Pat O'Brian, and Richard Thain. The representatives from CFI Transnational are Ron Lindsay and Tom Flynn.<br />
<br />
The Associate Members elect the Board of Directors. In addition to the current directors and the three who resigned there are six Associate Members: Chris DiCarlo, Jeffrey Rosenthal, Zak Fiddes, Ethan Clow, Bisi Bashorun, and Barry Karr. (Barry Karr is from CFI Transnational.)<br />
<br />
As far as I know, only three of these are active: Chris DiCarlo, Jeffrey Rosenthal, and Zak Fiddes.</blockquote><br />
<b>Sunday Meeting</b>    <br />
<blockquote>There's going to be a meeting this Sunday. It was called by a group of Associate Members. The first part of the meeting is between the Board of Directors and the three active Associate Members. The second part of the meeting is a Board meeting.<br />
<br />
The main item on the agenda is whether the firing of Justin Trottier was fair. I believe Justin will be at the meeting. There's talk of a plan to re-hire him in some capacity. It's clear that some members of the Board are sympathetic and it's clear that some are adamantly opposed. It doesn't look like the dissention within the Board has gone away after three resignations.<br />
<br />
Some of us tried to make the Sunday meeting an open meeting for all members of CFI but that plan met with firm resistance from the Directors.</blockquote><br />
<b>New Associate Members</b><br />
<blockquote>There's general agreement that we need new Associate Members. Several people have sent in applications. New members have to be approved by the Board of Directors. They will discuss this at the Sunday meeting.</blockquote><br />
<b>Rebranding</b><br />
<blockquote>The rebranding exercise is on hold, and so is everything else.</blockquote><hr width="200"/><font size="2"><blockquote></blockquote></font><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/37148773-9127699313317309944?l=sandwalk.blogspot.com' alt='' /></div>]]></content:encoded>

All you need to do is dangle a bit of bait and dozens of creationists will fight for the right to impale themselves on the hook. The latest victim is Jonathan McLatchie who responded to criticism of Phillip Johnson [<a href="http://www.evolutionnews.org/2011/12/jeffrey_shallit053841.html">Maligning Phil Johnson, with Lots of Rhetoric but Little Substance</a>]. I&#39;m sure the other bloggers on <i>Evolution News &amp; Views</i> don&#39;t see him as a fishy victim, they probably think of him as the designated hitter. (You could use &quot;sacrificial lamb&quot; if you want a Biblical metaphor.)<br />
<br />
Jonathan M, as he prefers to be known, is studying in Scotland for a Master&#39;s degree in evolutionary biology. He&#39;s upset with Jeffrey Shallit for criticizing Phillip Johnson&#39;s 1993 video (see <a href="http://recursed.blogspot.com/2011/12/this-video-should-be-shown-to-all.html">This Video Should Be Shown to all Biology Students</a>). He&#39;s also upset with my critiques of the same video (see <a href="http://sandwalk.blogspot.com/2011/12/phillip-johnson-one-of-very-best.html">Phillip Johnson, One of the Very Best Intelligent Design Creationists</a>). <br />

PZ Myers has a blog called <i>Pharyngula</i>&mdash;perhaps you've heard of it?<br />
<br />
He gave a talk on junk DNA at Skepticon IV in Sringfield, Missouri (USA) a few weeks ago. I disagree with a few thing he said,<br />
<br />
1. Some intron sequences are essential for splicing whereas PZ implies that they are all junk.<br />
2. Regulatory sequences make up less than 1% of your genome and not more than exons as PZ says [<a href="http://sandwalk.blogspot.com/2011/05/whats-in-your-genome.html">What's in Your Genome?</a>].  <br />
3. Half or your genome is <b>DEFECTIVE</b> transposon, not active transposons. Active transposons are not junk. Defective transposons are a form of pseduogene and they are definitely junk. The distinction is important.<br />
<br />
But the main point is that the IDiots predicted there wouldn't be any significant amount of junk in your genome and that prediction has been refuted.<br />

This time it's not sufficient to just give me the name of the molecule. You also have to briefly explain what it does and why it's important to some humans. The functional explanation has to be a biochemical explanation, not a physiological one.<br />
<br />
Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post <b><u>correct</u></b> answers to avoid embarrassment.<br />
<br />
There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.) Every undergraduate who posts a correct answer will have their names entered in a Christmas draw. The winner gets a free autographed copy of my book! (One entry per week. If you post a correct answer every week you will have ten chances to win.)<br />
<br />
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!) <br />
<br />
In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.   <br />
<br />
Winners will have to contact me by email to arrange a lunch date.<br />
<br />
<b>UPDATE:</b> The molecule is chlorothiazide of <a href="http://en.wikipedia.org/wiki/Hydrochlorothiazide">hydrochlorothiazide</a> or 6-chloro-1,1-dioxo-3,4-dihydro-2<i>H</i>-1,2,4-benzothiadiazine-7-sulfonamide. It's a drug commonly used to treat high blood pressure. Chlorothiazide belongs to a class of drugs that function as <a href="http://en.wikipedia.org/wiki/Diuretic">diuretics</a>&mdash;they decrease blood volume by preventing reabsorption of water from the urine.   <br />
<br />
The winner is 凌嘉誠 (Alex Ling). His answer emphasizes the role of the drug in inhibiting carbonic anhydrase and that's a valid property. However, the most important immediate effect is probably the inhibition of the Na<sup>+</sup>/Cl<sup>-</sup> transporter in the kidneys. As far as I can tell the effects of the drug at the molecular level are not as clear-cut as one would like. The decrease in blood volume appears to be temporary and the long-term effect in lowering blood pressure is probabably due to some unknown effect on veins and arteries.    <br />
<br />
<b>Winners</b><br />
Nov. 2009: Jason Oakley, Alex Ling<br />
Oct. 17: Bill Chaney, Roger Fan<br />
Oct. 24: DK<br />
Oct. 31: Joseph C. Somody<br />
Nov. 7:  Jason Oakley<br />
Nov. 15: Thomas Ferraro, Vipulan Vigneswaran <br />

He is running for the Republican nomination for President of the United States. In this video he is explaining why creationism should be taught in schools.<br />
<br />
The <i>Discover Institute</i> blog, <i>Evolution News & Views</i>, posted this video [<a href="http://www.evolutionnews.org/2011/12/santorum_gets_i053691.html">Santorum on Evolution: "It's Worth a Debate." Yeah, It is</a>]. It obvious that the IDiots consider Santorum to be a credible supporter of Intelligent Design Creationism. <br />
<br />
I suppose that's understandable given the quality of their other supportersl <br />

He has a Ph.D. in mathematics (University of Chicago, 1988), a Ph.D. in philosophy (University of Illinois (Chicago), 1993) and a Master's of Divinity (Princeton Theological Seminary, 1996). <br />
<br />
Here's a video explaining how Dembski can mathematically disprove evolution. Somehow this leads to proof of god. It may be difficult to follow the logic but that's probably because you and I don't have Ph.D.'s in mathematics or philosophy.<br />
<br />
Keep in mind that this is no amateur. Dembski is among the very best of the best in Intelligent Design Creationism. His speculations have been thoroughly refuted by prominent mathematicians, scientists, and philosophers. Under normal circumstances, this would be enough to cause his supporters to abandon him but he's still a fellow of the <i>Center for Science and Culture</i> and he's still promoted as one of the leading supporters of Intelligent Design Creationism.  <br />

The IDiots have been complaining of late that we aren&#39;t addressing their very best arguments in favor of Intelligent Design Creationism. They think we&#39;re just picking off the low-hanging fruit by attacking amateurs and Young Earth Creationists. This isn&#39;t true, but that&#39;s not a surprise since much of what they say isn&#39;t true.<br />
<br />
The Intelligent Design Creationists are celebrating the 20th anniversary of the publication of Phillip Johnson&#39;s <i>Darwin on Trial</i> [<a href="http://www.evolutionnews.org/2011/11/phillip_johnson053391.html">Phillip Johnson on the Scientific Nature of Opposition to Darwinian Theory</a>] [<a href="http://www.evolutionnews.org/2011/11/christian_post_darwin_on_trial053121.html"><i>Christian Post</i>: Darwin on Trial Still Resonates 20 Years Later</a>] [<a href="http://www.evolutionnews.org/2011/11/the_significance_of_phillip_jo053071.html">Why Phillip Johnson Matters: A Biography</a>]. It&#39;s clear that they think of Phillip Johnson as one of the leading proponents of Intelligent Design Creationism and that&#39;s quite reasonable since he was one of the key players at the beginning of the movement. I&#39;m going to assume that Phillip Johnson is not low-hanging fruit. He&#39;s among the very best that Intelligent Design Creationism has to offer or else they wouldn&#39;t be making such a big deal of this anniversary.<br />

 <br />
I get about 20 of these spam comments per day. Since I moderate comments they never get posted and you, dear readers, never see them. The <i>Blogger</i> spam catcher puts most of them in the spam bucket. <br />
<br />
So what's the point? The people posting these comments are wasting their time, and wasting my time as well. Is that the goal? I don't get it.<br />

<br />
Intelligent Design Creationism is a version of creationism that focuses on the creation of life. Proponents of this version claim that god played a direct role in creating some parts of living organisms. They concentrate on biochemical structures like bacterial flagella and folded proteins but they&#39;re also interested in things like speciation and the Cambrian explosion.      <br />
<br />
Evolution can explain most of the things that the Intelligent Design Creationists worry about so their main overt activities are concentrated on discrediting evolution and discrediting those scientists who support scientific explanations of biology. Given this necessity, you&#39;d think that the leading proponents of IDC would be quite knowledgeable about biology and evolution. <br />

<br />
Hoffmann noticed that there was less than unanimous agreement with his position so he replied on his blog <i>The New Oxonian</i>: <a href="http://rjosephhoffmann.wordpress.com/2011/11/30/the-sure-fire-atheist-rapid-response-manual/">The Sure-Fire Atheist Rapid Response Manual</a>. <br />

You really have to read it to see just what a sophisticated response from a Harvard/Oxford intellectual looks like. I think he's a bit annoyed at all the attention he's getting.<br />

<br />
The first is more openness. To that end I think the December 11th meeting in Toronto should be open to any member of the Centre for Inquiry. The meeting is at 10 am (Sunday). I assume it's at the CFI offices in Toronto. <br />
<br />
I expect that several people, including Justin Trottier and the Directors, will want to speak at that meeting. The objective is to explain exactly what's going on and how we got into this mess. <br />
<br />
The second thing we need to do is add more Associate Members. Candidates for Associate Membership can send an application to the Board of Directors.<sup>1</sup> The Board must approve these applications. Associate Members elect the Directors. There are only a dozen or so Associate Members and it's not clear how many of them are active in the Centre. <br />
<br />
If you have any ideas about what should, or should not, happen next, please bring them up in the comments below. <br />

Apparently it's going to be a long series ....<br />
<blockquote class="yellow"><i>I'm going to let ENV readers in on a little secret: When many of us in the intelligent design (ID) movement read the arguments coming from our critics, we're surprised at their low quality and style. We don't rejoice at this -- we'd much rather see a robust, civil, and fruitful scientific debate over the relevant questions. But the incivility, basic inaccuracy, and unserious tone characteristic of so many criticisms of ID all make you wonder: If the critics had stronger rebuttals to offer, wouldn't we be hearing them?<br />
<br />
...<br />
<br />
There are so many examples of incivility among ID-critics that it's hard to know where to start. And I'm not just talking about the usual Internet suspects, like PZ Myers, Jerry Coyne, or Larry Moran. </i></blockquote>On a completely unrelated topic that has nothing to do with Darwinist incivility ...<br />
<br />
While you're checking out <i>Evolution News & Views</i> you might want to read a fascinating article by Richard Weikart defending his books <i>From Darwin to Hitler: Evolutionary Ethics, Eugenics, and Racism in Germany</i> and <i>Hitler's Ethic: The Nazi Pursuit of Evolutionary Progress</i> [<a href="http://www.evolutionnews.org/2011/11/rallying_to_dar053511.html">Robert J. Richards and the Historical Record</a>]. It even has a photo to illustrate the point about Darwin (see below).<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-TQ4YpWTcymQ/TtVR7WB0v9I/AAAAAAAAL70/S7vQOkCB9JM/s1600/tmp.jpg" imageanchor="1" style="margin-left:1em; margin-right:1em"><img border="0" height="284" width="400" src="http://1.bp.blogspot.com/-TQ4YpWTcymQ/TtVR7WB0v9I/AAAAAAAAL70/S7vQOkCB9JM/s400/tmp.jpg" /></a></div><br />
This is a follow-up to a very civil article posted last month: <a href="http://www.evolutionnews.org/2011/10/can_darwinists_condemn_hitler052331.html">Can Darwinists Condemn Hitler and Remain Consistent with Their Darwinism?</a>.<br />
<blockquote class="yellow"><i>I threw down the gauntlet to many of my Darwinian opponents by telling her that if Darwinism is indeed a purposeless, non-teleological process, as many evolutionists and biology textbooks proclaim, and if morality is the product of these mindless evolutionary processes, as Darwin and many other prominent Darwinists maintain, then "I don't think [they] have any grounds to criticize Hitler."<br />
<br />
According to Flam, these are "fighting words." However, I have spoken with intelligent Darwinists who admit point-blank that they do not have any grounds to condemn Hitler, so I am not just making this up. Many evolutionists believe that since evolution explains the origin of morality -- as Darwin himself argued -- then there is no objective morality. The famous evolutionary biologist and founder of sociobiology, E. O. Wilson, and the prominent philosopher of science Michael Ruse co-authored an article on evolutionary ethics in which they asserted, "Ethics as we understand it is an illusion fobbed off on us by our genes to get us to co-operate."</i></blockquote>Anyway, let's not forget the important point and that's Casey Luskin's upcoming series on the incivility of ID critics.<br />

Apparently it&#39;s not sufficient to simply reject as unconvincing all of the arguments for the existence of god. We also have to study apologetics, which takes the existence of god as a premise!<br />
<br />
As if that weren&#39;t bad enough, we now have a group of philosopher types who insist that we study every atheist who ever lived. One of those philosopher types is R. Joseph Hoffman, a graduate from Harvard Divinity School and the University of Oxford. He is mainly interested in early Christianity. Hoffman is a nonbeleiver who posts at <i>The New Oxonian</i>. His latest post is: <a href="http://rjosephhoffmann.wordpress.com/2011/11/26/atheisms-little-idea-2/">Atheism’s Little Idea</a>.<br />

<br />
Andy Lewis received a letter from someone named Marc Stephens who claims to represent the Burzynski Clinic. You have to read this letter to understand what's going on [<a href="http://www.quackometer.net/blog/2011/11/the-burzynski-clinic-threatens-my-family.html">The Burzynski Clinic Threatens My Family</a>].<br />
<blockquote class="textbook">Le Canard Noir / Andy Lewis,<br />
<br />
I represent the Burzynski Clinic, Burzynski Research Institute, and Dr. Stanislaw Burzynski.  It has been brought to our attention that you have content on your websites http://www.quackometer.net/blog/2011/11/the-false-hope-of-the-burzynski-clinic.html that is in violation of multiple laws.<br />
<br />
Please allow this correspondence to serve as notice to you that you published libelous and defamatory information.  This correspondence constitutes a demand that you immediately cease and desist in your actions defaming and libeling my clients.<br />
<br />
Please be advised that my clients consider the content of your posting to be legally actionable under numerous legal causes of action, including but not limited to: defamation Libel, defamation per se, and tortious interference with business contracts and business relationships. The information you assert in your article is factually incorrect, and posted with either actual knowledge, or reckless disregard for its falsity.<br />
<br />
The various terms you use in your article connote dishonesty, untrustworthiness, illegality, and fraud.  You, maliciously with the intent to harm my clients and to destroy his business, state information which is wholly without support, and which damages my clients’ reputations in the community. The purpose of your posting is to create in the public the belief that my clients are disreputable, are engaged in on-going criminal activity, and must be avoided by the public.<br />
<br />
You have a right to freedom of speech, and you have a right to voice your opinion, but you do not have the right to post libelous statements regardless if you think its your opinion or not.  You are highly aware of defamation laws. You actually wrote an article about defamation on your site.  In addition, I have information linking you to a network of individuals that disseminate false information.  So the courts will apparently see the context of your article, and your act as Malicious.  You have multiple third parties that viewed and commented on your article, which clearly makes this matter defamation libel. Once I obtain a subpoena for your personal information, I will not settle this case with you.  Shut the article down IMMEDIATELY.<br />
<br />
GOVERN YOURSELF ACCORDINGLY.<br />
<br />
Regards,<br />
<br />
Marc Stephens<br />
Burzynski Clinic<br />
9432 Katy Freeway<br />
Houston, Texas 77055</blockquote>What would a normal person do after receiving such a letter? Ask for more information about the "defamatory" content. That's what Andy Lewis did and here's part of the response.<br />
<blockquote class="textbook">If you had no history of lying, and if you were not apart of a fraud network I would take the time to explain your article word for word, but you already know what defamation is. I’ve already recorded all of your articles from previous years as well as legal notice sent by other attorneys for different matters. As I mentioned, I am not playing games with you.  You have a history of being stubborn which will play right into my hands.  Be smart and considerate for your family and new child, and shut the article down..Immediately.  FINAL WARNING.<br />
<br />
Regards,<br />
<br />
Marc Stephens</blockquote>Yep, that's a threat you see in that paragraph.<br />

<br />
I teach a course on critical thinking about scientific issues such as evolution/creationism. Most (all?) of the &quot;scientific&quot; debates that enter the public realm can be divided into two groups: those where one side is right and the other side is wrong, and those where the issue is controversial. From a personal perspective, that means you can have three responses when asked if you agree with  a scientific argument: &quot;yes,&quot; &quot;no,&quot; and &quot;I don&#39;t know.&quot;<br />

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.) Every undergraduate who posts a correct answer will have their names entered in a Christmas draw. The winner gets a free autographed copy of my book! (One entry per week. If you post a correct answer every week you will have ten chances to win.)<br />
<br />
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!) <br />
<br />
In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.   <br />
<br />
<b>UPDATE:</b> The molecule is rifampicin, an inhibitor of bacterial RNA polymerase. The winner is Philip Rodger. Congratulations Philip, please send me an email message so we can arrange lunch. <br />
<br />
<b>Winners</b><br />
Nov. 2009: Jason Oakley, Alex Ling<br />
Oct. 17: Bill Chaney, Roger Fan<br />
Oct. 24: DK<br />
Oct. 31: Joseph C. Somody<br />

			<content:encoded><![CDATA[<blockquote class="textbook">NASA-funded researchers have evidence that some building blocks of DNA, the molecule that carries the genetic instructions for life, found in meteorites were likely created in space. The research gives support to the theory that a "kit" of ready-made parts created in space and delivered to Earth by meteorite and comet impacts assisted the origin of life. [<a href="http://www.nasa.gov/topics/solarsystem/features/dna-meteorites.html">NASA Researchers: DNA Building Blocks Can Be Made in Space</a>]</blockquote><center><iframe width="640" height="360" src="http://www.youtube.com/embed/Yavgy5-pqgI?rel=0" frameborder="0" allowfullscreen></iframe></center><br />
Most scientists are not thinking critically about the origin of life. It is extremely improbable that asteroids could have delivered enough amino acids or purines to make a difference. Given the known stability of these molecules in the ocean, you would have to achieve an enormous delivery rate to make a concentration sufficient to drive polymerization. It's much more likely that the first complex amino acids, and the first purines and pyrimidines, were synthesized in special environments on Earth using simple inorganic precursors. This is the origin of life scenario promoted as "Metabolism First" [<a href="http://sandwalk.blogspot.com/2011/01/more-prebiotic-soup-nonsense.html">More Prebiotic Soup Nonsense</a>].<br />
<br />
I wish NASA astrobiologists would stop making the assumption that all they have to do is discover complex organic molecules in asteroids in order to solve the origin of life. There are a lot of steps between finding purines in asteroids and making a prebiotic soup that could contribute to the origin of life. Those steps need to be spelled out in their press releases so the public can evaluate the discovery.<br />
<br />
Here's what I wrote a few years ago .... [<a href="http://sandwalk.blogspot.com/2009/04/can-watery-asteroids-explain-why-life.html">Can watery asteroids explain why life is 'left-handed'?</a>]<br />
<blockquote class="brown"><i>In order for extraterrestrial organic matter to have fueled the origin of life, a lot of meteorites carrying organic matter had to arrive on the primitive Earth. The problem of amino acid concentrations and stabiltity were discussed in a classic paper by Jeffrey Bada published in 1991. <br />
<br />
Some of his calculations are worth remembering. <br />
<br />
The current flux of extraterrestrial organic material is about 3 &times; 10<sup>8</sup> grams per year from cosmic dust and micrometeorites. About 1% of this is amino acids and most of them are not the ones found in living organisms. This should give rise over time to a concentration in the oceans of about 0.1 nM (10<sup>-10</sup> M). That's not sufficient for life to have originated. <br />
<br />
The flux in the past was almost certainly much greater and lots of organic material might have been delivered by large meteorites; however, it's unlikely that amino concentrations in the oceans could ever have been more than 10-100 pM for all amino acids combined.<br />
<br />
Most amino acids will spontaneously degrade over time. There's a window of opportunity that only lasts about 10 million years because in that time all the water in the oceans will pass through hydrothermal vents and the high temperature will destroy most chemicals&mdash;including amino acids. </i></blockquote>I don't know whether the NASA astronauts are aware of this problem but have developed a scenario to overcome it, or whether they just haven't thought about the problem.<br />

The Canadian Centre for Inquiry was founded in 2007 and the inaugural meeting was held in their rented facilities just south of the University of Toronto and a short walk from my office [<a href="http://sandwalk.blogspot.com/2007/03/centre-for-inquiry.html">Centre for Inquiry: March 10, 2007</a>].

CFI - Canada has now grown from the original Toronto (Ontario) branch to include branches in Vancouver, Okanagan, Calgary, Saskatchewan, Ottawa, Montreal, and Nova Scotia. There&#39;s paid staff in Toronto and there are now paid employees (usually part time) in several other centres. <br />

			<content:encoded><![CDATA[<blockquote class="textbook"><a href="http://en.wikipedia.org/wiki/De_mortuis_nil_nisi_bonum"><i>De mortuis nil nisi bonum</i></a> is a Latin phrase which indicates that it is socially inappropriate to say anything negative about a (recently) deceased person. Sometimes shortened to nil nisi bonum, the phrase derives from the sentence "de mortuis nil nisi bonum dicendum est" and is variously translated as "Speak no ill of the dead", "Of the dead, speak no evil", "Do not/ Don't speak ill of the dead" or, strictly literally, "Of the dead, nothing unless good".</blockquote>There are times when social conventions need to be violated. This is one of those times.<br />
<br />
Lynn Margulis died last Tuesday (November 22, 2011) at the age of only 73. Margulis is rightly famous for her endosymbiotic theory of the origins of mitochondria and chloroplasts. We known that she was right and she deserves credit for that part of her theory.<br />
<br />
However, since then (about 1970) her record has not been stellar and it's only appropriate that we keep this in mind as we reflect on her contribution to science. Here's a video of Lynn Margulis "defending" science by promoting the idea that one of the buildings of the World Trade Center in New York was brought down on Sept. 11, 2001 by explosives that had been planted in the building months before.<br />

I think he&#39;s mad at me [<a href="http://evolvingthoughts.net/2011/11/prescriptions-for-atheists/">Prescriptions for atheists</a>].<br />
<blockquote class="brown"><i>First, Larry points out that arguments about the existence of God require one to take a position on fairies. One can only be agnostic about gods to the extent one is agnostic about fairies. My previous argument that this is comparing unlikes has, in one fell swoop, been demolished!  Of course, there must be other reasons for thinking that we can rule fairies out of contention (let us call them faeries to avoid confusion) which do exist but are undetectable. It cannot be the principle that “if it is unscientific it is irrational” for that would be the positivist presumption and that would be unscientific. I know I am wrong about positivism here, because Dan Hicks pointed out that some positivists weren’t positivists about everything. So positivism is never self-defeating, even when the positivist presumption is applied by some to everything.<br />
<br />
Larry must have other reasons for showing that faeries do not exist – other than being uninterested in what some people claim; this, as Larry must appreciate, is not about what I the reasoner think is true, but about what others who make these claims must be called.

We&#39;ve been discussing the perceived conflict between agnosticism and atheism. I believe they are compatible. Most prominent atheists are also agnostic about the existence of supernatural beings. <br />
<br />
Part of the discussion has to do with how you define atheism. Many philosophers (professional and amateur) maintain that atheism is defined as &quot;the view that there is no God.&quot; This is the definition taken from <i>The Internet Encyclopedia of Philosophy</i>, which claims to be a &quot;peer-reviewed academic resource&quot; [<a href="http://www.iep.utm.edu/atheism/">Atheism</a>]. It seems to me that this view of atheism is widespread among philosophers, lending support to those who use it to justify rejecting atheism. <br />

Here&#39;s an excellent example from two different dictionaries.<br />
<br />
<blockquote><b>atheist:</b> a person who denies or disbelieves the existence of a supreme being or beings [<a href="http://dictionary.reference.com/browse/atheist">dictionary.com</a>]<br />
<br />
<b>atheist:</b> a person who does not believe in the existence of God or gods [<a href="http://oxforddictionaries.com/definition/atheist">Oxford Dictionaries</a>]</blockquote>The first definition defines an atheist as someone who maintains that gods do not exist. The second defines an atheist as someone who is not a theist. <br />
<br />
The distinction is relatively unimportant in everyday usage since most of us who are nontheists will argue that gods do not exist. But when you&#39;re arguing with a philosopher you need to pick nits since philosophical arguments often turn on definitions. No intelligent atheist wants to be trapped into arguing that gods do not exist since that&#39;s like trying to &quot;prove the negative&quot; and we all know that it is impossible to prove the nonexistence of something.  <br />

She recently gave me a little book called <a href="http://www.genealogical.com/products/My%20Ancestors%20Came%20with%20the%20Conqueror/878.html"><i>My Ancestors Came with the Conqueror</i></a> by Anthony J. Camp, first published in 1988. Camp is a professional genealogist. Before discussing this book, I should let you know that the relationship between professional genealogists and the amateur genealogy found on <a href="http://www.ancestry.com/"><i>ancestry.com</i></a> is similar to the relationship between scientists and Intelligent Design Creationism.<br />
<br />
It's estimated that half the population of Great Britain claims to have descended from William the Conqueror who defeated King Harold at the Battle of Hastings in 1066. Not all claims meet the rigorous standards of professional genealogists but it's quite reasonable that there are millions of direct descendants of William. <br />
<br />
Back in 1400 it was less likely that you were a descendant of William because there were fewer generations and fewer descendants. This was a problem for aspiring nobility and minor landholders so they tended to settle for the next best thing&mdash;they claimed descent from one of the companions of William who accompanied him from Normandy and fought at the Battle of Hastings. Gradually the list of companions grew and grew because if you couldn't prove you were related to an existing companion, you just made one up.   <br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-rYDQtax0hIM/Ts5rek1rOhI/AAAAAAAAL3Q/g43rhcV7MQo/s1600/tmp.bmp" imageanchor="1" style="clear:left; float:left;margin-right:1em; margin-bottom:1em"><img border="0" height="400" width="309" src="http://2.bp.blogspot.com/-rYDQtax0hIM/Ts5rek1rOhI/AAAAAAAAL3Q/g43rhcV7MQo/s400/tmp.bmp" /></a></div>Many genealogists and historians have analyzed the various lists of companions. Some lists have over three hundred names but there are only about 20 companions who are definitely known to have been present at the Battle of Hastings in 1066 [<a href="http://freepages.genealogy.rootsweb.ancestry.com/~randyj2222/wm_conq.html">William the Conqueror's Companions</a>, <a href="http://www.robertsewell.ca/conquest.html#companions">The Companions of the Conqueror</a>]. <a href="http://augustan.ens-2.com/cpage.php?pt=15">The Order of the Conqueror’s Companions</a> is part of a genealogical society that traces descendants of the companions of William the Conqueror. They list 39 known companions. <br />
<br />
Let's assume that there are 20 well-documented companions. Only one of these (William Mallet) has possibly passed on his Y chromosome to the present time and even that male line of descent is disputed. This is fully consistent with our understanding of genetics when you consider that most male lines are likely to die out in a few generations. Those that survive ten generations or so are unlikely to become extinct since there will likely be several male lines at that time.<br />
<br />
Only 10 of the companions have descendants who are alive today. This could be due to the fact that genealogists don't have perfect records for all the companions and their families but it's also quite in line with expectations.<sup>1</sup> You don't expect that all 20 families will avoid extinction. What this means is that for a random "population" of 40 individuals (20 companions plus their wives), only 20 of them contributed alleles to the present population after 50 generations.<sup>2</sup> <br />
<br />
The take-home lesson from these genealogical studies is that the actual population size at a given point in time is not the same as the actual number of individuals who contribute to the gene pool over the long term.<br />
<br />
This has long been known to population geneticists. They define a new term, <i>N<sub>e</sub></i>, called the "effective population size." In order to understand the definition of effective population size, you have to keep in mind that most of the variation in a given population is due to the presence of nearly neutral alleles whose frequency is fluctuating under the influence of random genetic drift. The parameter of interest, <i>N<sub>e</sub></i>, represents the theoretical number of individual in a population of size <i>N</i> who actually contribute to the variation in a population. <br />
<br />
The definition is from Sewell Wright [<a href="http://en.wikipedia.org/wiki/Effective_population_size">Effective Population Size</a>] ...<br />
<blockquote class="textbook"><i>Effective population size is "the number of breeding individuals in an idealized population that would show the same amount of dispersion of allele frequencies under random genetic drift or the same amount of inbreeding as the population under consideration."</i></blockquote>The effective population size is always less than the actual population (<i>N<sub>e</sub></i> < <i>N). Sometimes it's a lot less. In most vertebrates, for example, the long-term effective population size is calculated to be about 10,000.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-2OOaDbzb8lU/Ts58k4-jvUI/AAAAAAAAL3c/-pzFS6scw5E/s1600/The+Origins+of+Genome+Architecture.jpg" imageanchor="1" style="clear:right; float:right; margin-left:1em; margin-bottom:1em"><img border="0" height="382" width="280" src="http://3.bp.blogspot.com/-2OOaDbzb8lU/Ts58k4-jvUI/AAAAAAAAL3c/-pzFS6scw5E/s400/The+Origins+of+Genome+Architecture.jpg" /></a></div>Why is this important? It's important because evolution is important for understanding biology and in order to understand evolution you need to understand population genetics. One of the important lessons from population genetics is that the relative important importance of natural selection and random genetic drift is dependent on effective population size. This is a major theme in Michael Lynch's book <i>The Origins of Genome Architecture</i>.<br />
<br />
He argues that the effective population size of most large multicellular animals (e.g. <i>Homo sapiens</i>) was small enough to render natural selection impotent for most alleles that might have been somewhat beneficial in larger populations. This led to loss of such beneficial alleles by random genetic drift and to frequent fixation of mildly deleterious alleles by drift. Thus, even if the accumulation of large amounts of junk DNA, for example, was slightly deleterious, it cannot be eliminated by natural selection when the effective population size is small. <br />
<br />
Furthermore, many alleles with small beneficial effects cannot possibly become fixed in such a population so it's silly to construct a model that relies on fixation of alleles with a small advantage. This leads to his theory of the evolution of genome complexity by nonadaptive processes. According to Lynch, the default explanation is random genetic drift and because this accounts for much of genome architecture, there's no reason to invoke natural selection to explain what we observe.       <br />
   <br />
Lynch devotes an entire chapter (Chapter 4) to <i>Why Population Size matters</i>. I'm hoping to get more people interested in this subject by giving them a simple example of the difference between actual population size (<i>N</i>) effective population size (<i>N<sub>e</sub></i>). <br />
<br />
This isn't only important in genome evolution. As most of you know, the effective population size is an important consideration in recent human evolution [<a href="http://johnhawks.net/research/hawks-2008-genes-numbers-effective-size">From genes to numbers: effective population sizes in human evolution</a>] and many other disciplines.   <br />
<br />
<hr width="200"/><font size="2"><blockquote>1. The reason we focus on nobility isn't because they are more important, genealogically, than the 8,000 other soldiers at the battle. It's because we don't have any records of those other potential ancestors. <br />
<br />
2. This doesn't mean that all of the alleles in the other 20 individuals were lost because many of them could have been passed down from siblings, aunts, uncles etc. <br />

<br />
My position is similar to that of Richard Dawkins, and many others. I am an atheist (i.e. not a theist) because there is no convincing evidence for gods, in my opinion. Thus, I do not believe in them (not-a-theist).<br />
<br />
There is always a possibility that gods actually exist even though I see no evidence for them. I cannot prove that they are all non-existent. Thus, I am, in a sense agnostic on the possibility of gods existing, although I think the odds are incredibly small.<br />
<br />
Like Dawkins, "I am agnostic only to the extent that I am agnostic about fairies at the bottom of the garden." I am a practicing atheist because I do not believe in gods but I am philosophically agnostic as well. I have theist friends who believe in God but are also agnostic.<br />
<br />
John says,<br />
<blockquote class="brown"><i>Let me be quite clear on this: I do not think there is evidence for a God, as an agnostic. And I certainly think there is evidence against many stories and characterisations of gods. But, and this seems to be the point that strong “skeptics” like Hecht cannot get into their heads, not all. So long as there is a formal possibility that some gods might exist, and no general evidence against it, the rational thing to do is hold off judgement on the (empirically permissible) claims. So Thor doesn’t exist, but Leibniz’s deity might.</i></blockquote>Like me, John, doesn't believe in gods&mdash;he is not a theist. But he is not an a-theist in spite of the fact that if you followed him around for several days you could not distinguish his bevavior from that of any other non-believer. <br />
<br />
We agree that there's a possibility that some sort of gods exist but we both have declined to become believers (theists). Yet, I am a strong atheist/agnostic while John is a nonbeliever but only an agnostic.  <br />
<br />
Have I got that right, John?<br />
<br />
As an amateur philosopher, it seems to me that you could apply the same logic to the existence of fairies or UFO astronauts with a fixation on body openings. There's no evidence that they exist so we don't believe in them. But as long as there's a formal possibility that they exist&mdash;and there is&mdash;we have to be agnostic about their existence.<br />
<br />
For some reason we don't go around announcing to the world that we are agnostic about the existence of fairies, UFOs, and Santa Claus. Why? Doesn't the formal possibility of their existence merit consideration? Don't we recognize that we could never PROVE that fairies don't exist?<br />
<br />
The word "agnostic" only ever applies to the belief in gods and never&mdash;in common speech&mdash;to fairies. We all know the reason for this. It's accommodationism. It's a way to avoid insulting our religious friends by proclaiming you don't believe in their gods. Too bad it's almost always atheists who are so sensitive. You don't see many theists avoiding the word "theist" in favor of "agnostic." <br />
  <br />
Part of the problem is that agnostics like John tend to use a different definition of "atheist" than we do. He seems to think that it means we deny the possibility that gods exist. I think that's why he considers "atheist" and "agnostic" to be non-overlapping sets.   <br />

It surveyed Canadians about religion. Only 16% of Canadians attend church every week and about 30% of Canadian say they don't believe in God. Only 53% of Canadians say they believe in God. This is good news for those of us who think the trend is in the right direction. It's bad news for those who think that the religious views of society can't be changed.<br />
<br />
Here's a news story from Global news on September 12, 2011 [<a href="http://www.globalmaritimes.com/poll/6442480278/story.html">Canadians divided on whether religion does more harm than good: poll</a>].

<blockquote><i>WHY RUSSIANS ARE BUILDING A PYRAMIDAL COMPLEX IN SIBERIA: In the last 15 years there has been an organized effort in Russia to study ancient technologies from around the globe, especially in Egypt. Studies conducted by top scientists from Russian academia, headed by Mr. Uvarov have made amazing findings. Come and find out why pyramids are being built, how the energy of pyramids and Wands of Horus influence the immune system; how pyramids are antennas and amplifiers of “life force” – energy bands that are beneficial for humans; how the pyramid’s energy field corrects/purifies all materials nearby, especially water; and what will happen in 2012. Mr. Uvarov has published two books about pyramids and the Wands of Horus.</i> [I remember the Wands of Horus ... it's from Zork, right? -LAM]</blockquote><br />
<b>Paul MacDonald</b><br />
<blockquote><i>Would you like to be in perfect balance, physically, mentally, and spiritually? Join Paul MacDonald, preeminent Biontologist in North America, and learn how that balance can be achieved. Every living cell in the body emits biophotonic light. Paul will describe how chaotic light impulses indicate disturbance in the body, and how that light can be neutralized to successfully treat depression, heart disease, migraines, and other symptoms that incoherent light presents. You will also learn how to become a biontologist and set up your own practice.</i> [Does your biophotonic light keep your partner awake at night? -LAM]</blockquote>I'm tempted to say that you "just can't make this stuff up" but then I realized that's exactly what these quacks are doing! I can see why they they're afraid of skeptics. I wonder if any genuine newspaper reporters will cover this? <br />

There is considerable controversy over whether this molecule actually exists in most cells.<br />
<br />
Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post <b><u>correct</u></b> answers to avoid embarrassment.<br />
<br />
There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.) Every undergraduate who posts a correct answer will have their names entered in a Christmas draw. The winner gets a free autographed copy of my book! (One entry per week. If you post a correct answer every week you will have ten chances to win.)<br />
<br />
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!) <br />
<br />
In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.   <br />
<br />
<b>UPDATE:</b> This one was more difficult than I expected. The molecule is oxalosuccinate or 1-oxopropane-1,2,3-tricarboxylate. I posted all the answers that used this IUPAC name or 1-oxopropane-1,2,3-tricarboxylic acid. This is clearly not the acid form of the molecule but that didn't make you ineligible to win the prize.<br />
<br />
Oxalosuccinate is thought to be a transient intermediate in the reaction catalyzed by isocitrate dehydrogenase (citric acid cycle) but this is only a hypothesis&mdash;the intermediate has never been detected.<br />
<br />
The molecule contains a chiral carbon atom (C3 of oxalosuccinate and C2 of oxopropane). I was expecting all answers to specifically identify the [2S] or [3S] stereoisomer, especially since we had recently discussed stereoisomers on this blog. "Cyau" was the only one to get this correct (on her second try) but she is not eligible because she didn't identify herself.<br />
<br />
RaulFelix was the first person to name the molecule as 1-oxopropane-1,2,3-tricarboxylate and she would be the winner if I knew her real name. That means Vipulan Vigneswaran is this week's winner, beating out Joseph Somody by less that one minute. <br />
<br />
<b>Winners</b><br />
Nov. 2009: Jason Oakley, Alex Ling<br />
Oct. 17: Bill Chaney, Roger Fan<br />
Oct. 24: DK<br />
Oct. 31: Joseph C. Somody<br />
Nov. 7: Jason Oakley<br />
Nov. 15: Thomas Ferraro, Vipulan Vigneswaran <br />

It was horrible. As I noted at the time, "The document is flawed from the beginning because it gives credence and respectability to "alternative medicine," otherwise known as non-evidence based medicine or quackery" [<a href="http://sandwalk.blogspot.com/2011/08/non-allopathic-non-conventional.html">Non-Allopathic (Non-Conventional) Therapies in Medical Practice</a>]. <br />
<br />
Many groups took notice of the draft policy and criticized the Ontario College of Physicians Surgeons for their gutless response to a serious crisis in health. One of those groups was the Committee for the Advancement of Scientific Skepticism, a committee of Canada's Centre for Inquiry [<a href="http://www.cficanada.ca/blogs/show/media_advisory_ontario_doctors_given_the_green_light_to_promote_quackery/">Media Advisory: Ontario Doctors Given the Green Light to Promote Quackery</a>]. The members of CASS worked hard to lobby for changes and they co-ordinated their activities with several other groups that are opposed to the weak-kneed position of the College.<sup>1</sup> The College conducted a survey of its members and discovered that 78% of them opposed the draft policy. About one third of the people who filled out the survey were directed to the site by CASS or its allies [<a href="http://www.skepticnorth.com/2011/10/skeptical-activism-sends-a-message-to-cpso/">Skeptical Activism Sends a Message to CPSO</a>. Very impressive.<br />
<br />
Those behind-the-scenes activities had an impact as more and more people voiced their criticism on the <a href="http://www.cpso.on.ca/policies/consultations/default.aspx?id=5112">FeedBack Site</a>. <br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-ftgwtOVcsGo/Tsp3vQbqKYI/AAAAAAAAL1M/NgrCzddFkd0/s1600/CASS+Logo.jpg" imageanchor="1" style="clear:left; float:left;margin-right:1em; margin-bottom:1em"><img border="0" height="320" width="307" src="http://4.bp.blogspot.com/-ftgwtOVcsGo/Tsp3vQbqKYI/AAAAAAAAL1M/NgrCzddFkd0/s320/CASS+Logo.jpg" /></a></div>All this lobbying convinced the <i>Toronto Star</i> newspaper that something serious was afoot and yesterday, Sunday Nov. 20, 2011, the newspaper published an editorial that sides with science [<a href="http://www.thestar.com/opinion/editorials/article/1089492--don-t-muzzle-our-doctors">Don’t muzzle our doctors</a>]. The paper deserves praise for getting it right and giving us hope that science will win in the end..<br />
<blockquote class="brown"><i>Patients walk into allergist Dr. David Fischer’s office almost every day expressing interest in trying “natural” therapies. These range from harmless diet changes to the truly bizarre, like applied kinesiology, says the Barrie physician. It’s an experience shared by other doctors. “We’re on the front line of dealing with ideas for which there is often a dearth of scientific evidence.”<br />
<br />
Alternative medicine is booming even without much proof it works. A record 20,000 people are expected at Toronto’s Whole Life Expo at the downtown convention centre next weekend. Three-quarters of Canadians regularly use some form of natural health product, opening their wallets to spend at least $4.3 billion yearly. And the herbs and homeopathic tinctures they buy are just one facet of unconventional medicine — a thriving sector encompassing everything from acupuncture to zone therapy (supposedly stimulating the body’s organs through hand or foot massage).<br />
<br />
Ontario’s College of Physicians and Surgeons is bending to the trend with a new policy inhibiting doctors’ criticism of unconventional therapies. In doing so it risks encouraging even broader use of dubious and potentially harmful treatments.<br />
<br />
Make no mistake — blind trust in alternative cures can be dangerous. An unknown number of Canadians are opting out of science-based medicine to treat even deadly conditions, like cancer, with unproven “natural” approaches.<br />
<br />
....<br />
<br />
The field of allergy medicine, Fischer’s specialty, is especially prone to alternative approaches. Natural practitioners using applied kinesiology, for example, check for allergy by placing a food item in a patient’s mouth or in their hand. Then they pull down on the person’s free arm to assess its strength. If this “muscle testing” shows notable weakness, the patient is deemed to be allergic.<br />
<br />
There is no good evidence that this method works, and no sound scientific reason why it should. Yet patients come in with an interest in that, says Fischer. “I’d like to be able to tell them it’s quackery.”<br />
<br />
He may not be in a position to say so much longer under a new policy proposed by the college of physicians and surgeons. It states that doctors are obliged to give a patient their best professional opinion on an alternative treatment goal or decision, but physicians “must refrain from expressing personal, non-clinical judgments.”<br />
<br />
....<br />
<br />
There’s no denying alternative medicine is immensely popular. Patients are more independent than ever before, often researching their illness and trusting their own solutions. And a host of unconventional “natural” healers has risen capitalizing on that trust — offering unproven therapies with little validity and which, in some cases, are a menace.<br />
<br />
The college shouldn’t seek to accommodate that trend or retreat to a neutral corner. Rather it should leave doctors free to punch hard against those peddling dubious cures and to challenge people’s comforting, but irrational, beliefs. Science-based medicine serves patients best. If doctors can’t vigorously defend it, who will?</i></blockquote><br />

<br />
It was PZ Myers who got me started.<sup>1</sup> We were in England visiting Down House when he convinced me that starting a blog was better than posting messages on talk.origins. He took the picture of me on the upper-left-hand corner of this page Can you guess where we were? He also took the one in this post. <br />
<br />
3811 posts later I'm still not sure whether to thank PZ or curse him. <br />
<br />
On <a href="http://sandwalk.blogspot.com/2010/11/happy-blogiversary-sandwalk.html">last year's blogiversary</a>, none of the top five postings on <i>Sandwalk</i> were about science. This has now changed. As of today, four of the top five all-time postings are science postings.<br />

John Hawks posts a reference to an article in MacLeans magazine about undergraduate teaching. John supports a style of teaching that emphasizes &quot;hands-on&quot; experience over learning about theory [<a href="http://sandwalk.blogspot.com/2011/11/problem-with-stem.html">The Problem with Stem</a>, <a href="http://johnhawks.net/weblog/topics/teaching/stem-dropouts-2011.html">A reason for practical genomic education</a>].<br />
<br />
Like many critics of education, John thinks that traditional lectures are old-fashioned and inefficient. I tend to agree with him on this point—we can do a much better job of education in a classroom setting. However, I part company with many critics who go overboard in rejecting traditional lecture formats as a way of communicating information. For example, I note that this style is readily accepted in many other contexts. John Hawks gave a talk last week n Madison that I would love to have attended [<a href="http://sandwalk.blogspot.com/2011/11/i-would-so-go-to-this-if-i-were-in.html">I would so go to this if I were in Madison</a>]. There are all kinds of other public lectures that people pay good money to attend—we filled an auditorium when PZ Myers acme to town. Traditional lectures are very common at scientific meetings because nobody has figured out a better way to hear what an expert has to say. <br />
<br />
The death of lectures has been greatly exaggerated.<br />

Now that you&#39;ve learned about Fischer Projections [<a href="http://sandwalk.blogspot.com/2011/11/better-biochemistry-fischer-projections.html">Better Biochemistry: Fischer Projections</a>] you&#39;re deady to tackle a more challenging problem. But first some background.<br />
<br />
Glycerol phosphate is a major precursor in the synthesis of triacylglycerides and related compounds. These are the major lipid components of membranes. Here&#39;s a simplified pathway to show the importance of the glycerol backbone. (&quot;R&quot; stands for long-chain fatty acids.) I&#39;ve deliberately avoided naming the glycerol-phosphate precursor because it requires a bit of thought.<br />

Brandon appears to be one of those theists. He's a Roman Catholic philosopher with a blog called <i>Siris</i> and he recently posted a rejoinder called <a href="http://branemrys.blogspot.com/2011/11/when-atheists-try-to-be-clever.html">When Atheists Try to Be Clever... </a>.<br />

Brandon noticed that the board has no kings. (Aren't those philosophers clever?) It also doesn't have any bishops but he doesn't mention that. In spite of the fact that the board is missing a few pieces, Brandon thinks that the standard rules of chess should apply ...<br />
<blockquote class="brown"><i>... it nonetheless ends up backfiring because ... it is logically and mathematically impossible, given any standard rules of chess, for either side to win this game. The rules of chess require an automatic draw if there is an impossibility of checkmate -- once it is established that no legal series of moves can reach checkmate, the game is over and both sides tie. A game with no kings has no possible checkmate, and so is an immediate draw. In trying to depict with a chessboard how much better their arguments are, a task in which they had perfect freedom to choose any possible chess set-up, they still managed to give themselves an unwinnable board. In other words, the atheist player doesn't know what he's getting into: the board is rigged so that the theist, with nothing but pawns, can guarantee a draw no matter how many queens the atheist has. Diabolically clever theist, getting atheist hopes up while making it impossible for them to win! That's on standard rules. And, of course, if the rules are supposed to be nonstandard, it is impossible to know what this board even means.</i></blockquote>Looking at the board, you can can imagine that the contest will end when all the pawns have been wiped out and there are 15 queens left. At this point the theists will declare a draw because an imaginary, nonexistent, king has not been captured. Yep, that certainly sounds like an argument from a theist.<br />
<br />
It also&mdash;for some strange reason&mdash; reminds me of <a href="http://sandwalk.blogspot.com/2011/05/black-knight.html">The Black Knight</a>. ("Right, we'll call it a draw.")<br />
<br />
John Wilkins, who is also a philosopher, thought Brandon's "rejoinder" was clever enough to deserve a mention on his own blog [<a href="http://evolvingthoughts.net/2011/11/agnostic-versus-atheist-chess/">Agnostic versus atheist chess</a>]. I guess you don't have to be a theist to believe in imaginary, nonexistent, chess pieces. <div><a href="http://3.bp.blogspot.com/-jlGzeRWxMjI/TsUYfUO67hI/AAAAAAAAL0M/LOJRtDOW3P0/s1600/smile.gif" imageanchor="1" style=""><img src="http://3.bp.blogspot.com/-jlGzeRWxMjI/TsUYfUO67hI/AAAAAAAAL0M/LOJRtDOW3P0/s400/smile.gif" /></a></div><br />

One of the lines of evidence has to do with sequence conservation. If most of the genome sequences are not conserved between species this strongly suggests that they have no function, although it doesn&#39;t rule out a function that is independent of sequence.<br />
<br />
Wells addresses this argument in: <a href="http://www.uncommondescent.com/intelligent-design/jonathan-wells-on-darwinism-science-and-junk-dna/">Jonathan Wells on Darwinism, Science, and Junk DNA</a>. Before analyzing his response, it&#39;s worth reviewing what he wrote in <i>The Myth of Junk DNA</i>. <br />
<br />
In chapter 5, Wells talks about sequence conservation as evidence of function—specifically the fact that the sequences of some potential pseudogenes are more conserved that would be expected if they were really pseudogenes [<a href="http://sandwalk.blogspot.com/2011/05/junk-jonathan-part-8chapter-5.html">Junk &amp; Jonathan: Part 8—Chapter 5</a>]. That&#39;s an important argument and, if true, it would point to a function. The irony is that Wells doesn&#39;t believe in common descent so, from his perspective, these are not <u>conserved</u> sequences due to negative natural selection. Nevertheless, he is happy to use evolutionary arguments whenever it suits him.<br />

Give me the complete, unambiguous, name of this molecule to win a free lunch. Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post <b><u>correct</u></b> answers to avoid embarrassment.<br />
<br />
There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.) Every undergraduate who posts a correct answer will have their names entered in a Christmas draw. The winner gets a free autographed copy of my book! (One entry per week. If you post a correct answer every week you will have ten chances to win.)<br />
<br />
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!) <br />
<br />
Name the molecule shown in the figure. Remember that your name has to be unambiguous. The best way to do this is to use the full IUPAC name but usually there are traditional names that will do. In this case there's a trivial name and that will suffice.<br />
<br />
In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.   <br />
<br />
<b>UPDATE:</b> Several people got this one right. The molecule is prostaglandin H2. The winner is Thomas Ferraro. The undergraduate winner is "Vip" = Vipulan Vigneswaran.<br />
<br />
<b>Winners</b><br />

For example, we often have difficulty envisaging how a three-dimensional substrate binds to a three-dimensional enzyme. <br />
<br />
The problem is exacerbated because we usually teach in two dimensions for simplicity—especially in textbooks.<sup>1</sup> There are certain rules that have to be followed when displaying a three-dimensional object on a two-dimensional page. This is especially true for metabolites where the stereochemistry is crucial. One of these rules is called the Fischer projection.<sup>2</sup> <br />
<br />
Most students (and faculty) don&#39;t understand the relationship between a two-dimensional Fischer projection and the three-dimensional molecule it&#39;s supposed to represent. This is unfortunate because it means they don&#39;t really understand the three-dimensional conformation of metabolites.<br />
<br />
Let&#39;s look at a simple three-carbon compound—glyceraldehyde. There are two different versions of glyceraldehyde: D-glyceraldehyde and L-glyceraldehyde. The two different molecules cannot be superimposed, that&#39;s why you know that they are different molecules. Enzymes can tell the difference; that&#39;s why D-glyceraldehyde is a common metabolite and L-glyceraldehyde is rarely found in cells.<br />

The fact that our genome has huge amounts of junk DNA is not just an argument from ignorance—an argument that most IDiots are familiar with—because there are several good reasons for concluding that most DNA has to be junk.<br />
<br />
Wells addressed those arguments in: <a href="http://www.uncommondescent.com/intelligent-design/jonathan-wells-on-darwinism-science-and-junk-dna/">Jonathan Wells on Darwinism, Science, and Junk DNA</a>.<br />

<br />
We'll get to those issues in another post but right now I want to take note of something Wells said at the end of his article.<br />
<blockquote class="yellow"><i>Oh, one last thing: “paulmc” referred to an online review  of my book by University of Toronto professor Larry Moran—a review that “paulmc” called both extensive and thorough. Well,  saturation bombing is extensive and thorough, too. Although “paulmc” admitted to not having read more than the Preface to The Myth of Junk DNA, I have read Mr. Moran’s review, which is so driven by confused thinking and malicious misrepresentations of my work—not to mention personal insults—that addressing it would be like trying to reason with a lynch mob.</i></blockquote>I can understand why Wells might decline to post a comment on <i>Sandwalk</i>. Many of us know what it's like to try and argue with the readers of the intelligent design blogs. Wells would meet the same reception here that we get over there.<br />
<br />
But that doesn't preclude Wells from posting on <i>Uncommon Descent</i> or <i>Evolution News & Views</i>. If he really believes that my review of his book is an example of "confused thinking and malicious misrepresentations of my work"<sup>1</sup> then why not back up such a statement with a thoughtful response on a friendly blog? <i>Evolution News & Views</i> would be ideal since comments are banned.<br />
<br />
<hr width="200"/><font size="2"><blockquote>1. Wells has accused other scientists of misrepresentation. It's a common theme in <i>The Myth of Junk DNA</i> and in <i>Icons of Evolution</i>. I quoted this passage in <a href="http://sandwalk.blogspot.com/2011/10/junk-jonathan-part-13chapter-10.html">Junk & Jonathan: Part 13—Chapter 10</a>.<blockquote><i>Coyne and Avise are professors of genetics at major universities, so they cannot claim ignorance of the genomic evidence without thereby admitting negligence or incompetence. In fact, one of Coyne's colleagues at the University of Chicago is James Shapiro, co-author of the 2005 article cited in Chapter 6 that listed over 80 known functions for non-protein-coding repetitive DNA. [The other author is Richard (von) Sternberg ... LAM] But if Coyne and Avise were not ignorant of the evidence, then they misrepresented it—and they continue to do so. Like Dawkins, Shermer and Kitcher they have forfeited any claim they might have to be speaking for science. </i></blockquote>I can understand why Wells is reluctant to defend such statements. It's because they are indefensible.<br />

			<content:encoded><![CDATA[ <br />
There have been lots of new books about evolution in the past decade or so. I tend to divide them into three categories:<br />
<ol><li><b>The Standard View</b>: These are books that basically support the Modern Synthesis with some small tweaks here and there. They do not advocate major shifts in the way we look at evolution. Books by Richard Dawkins (<i>The Greatest Show on Earth: The Evidence for Evolution</i>), Jerry Coyne (<i>Why Evolution Is True</i>), Sean B. Carroll (<i>Endless Forms Most Beautiful: The New Science of Evo Devo and the Making of the Animal Kingdom</i>, <i>The Making of the Fittest: DNA and the Ultimate Forensic Record of Evolution</i>), and Ken Miller (<i>Only a Theory</i>) fall into this category.</li>
<li><b>The New View</b>: Some books make the case for a new way of looking at evolution. I&#39;ll call it the &quot;New View.&quot; Many of Stephen Jay Gould&#39;s books fall into this category (<i>The Structure of Evolutionary Theory</i>). He refers to it as extending the modern synthesis. Most of the &quot;extension&quot; is based on a pluralist, rather than an adaptationist approach but other modifications are important. Two recent books by Michael Lynch (<i>Origins of Genome Architecture</i>) and Eugene Koonin (<i>The Logic of Chance: The Nature and Origin of Biological Evolution</i>) fall into this category. It&#39;s a view that I share.</li>
<li><b>The Radical View</b>: Some books advocate a more-or-less complete overthrow of the Modern Synthesis, replacing it with the author&#39;s pet theory. Examples are: Marc Kirschner, and John Gerhart (<i>The Plausibility of Life: Resolving Darwin&#39;s Dilemma</i>), James Shapiro (<i>Evolution: A View from the 21st Century</i>), Lynn Margulis and Dorion Sagan (<i>Acquiring Genomes: A Theory Of the Origin Of Species</i>), Massimo Pigliucci and Gerd B. Müllerand (editors) (<i>Evolution - the Extended Synthesis</i>), many others.</li>

The new buzzword in science education is STEM: science, technology, engineering, and math. In America, there are dozens of studies on how to improve STEM education at all levels—including universities. Leading scientists have signed on.<br />
<br />
Here&#39;s the problem. &quot;Science&quot; is NOT the same as &quot;technology&quot; and not the same as &quot;engineering.&quot; There&#39;s a big difference between learning science and learning how to build things. The purpose of a degree in technology and engineering is obvious—it&#39;s job training. The purpose of a science education is quite different—it&#39;s supposed to teach you how to think critically.<br />
<br />
But that distinction seems to have been lost on politicians, the general public, the media, and—most disappointingly—my fellow scientists. A recent article in <i>The New York Times</i> illustrates the extent of the problem [<a href="http://www.nytimes.com/2011/11/06/education/edlife/why-science-majors-change-their-mind-its-just-so-darn-hard.html">Why Science Majors Change Their Minds</a>].<br />

<div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-XV5kxtwPJv0/TryWp5x0eVI/AAAAAAAALuM/uQqfsiqyQj4/s1600/idiots.jpg" imageanchor="1" style="clear:right; float:right; margin-left:1em; margin-bottom:1em"><img border="0" height="337" width="352" src="http://2.bp.blogspot.com/-XV5kxtwPJv0/TryWp5x0eVI/AAAAAAAALuM/uQqfsiqyQj4/s400/idiots.jpg" /></a></div>Over on <i>Uncommon Descent</i> we've been discussing junk DNA [<a href="http://www.uncommondescent.com/intelligent-design/heres-jonathan-wells-on-destroying-darwinism-and-responding-to-attacks-on-his-character-and-motives/">Here’s Jonathan Wells on destroying Darwinism – and responding to attacks on his character and motives</a>]. One of the IDiots (Joseph) has proposed a modification of the existing scientific theory of intelligent design. The new version now accounts for junk DNA. <br />
<br />
You might think this is just his personal take on intelligent design but I asked everyone else to comment if they objected to his ideas. After more than 24 hours, nobody raised any objection so I assume Joseph's ideas are acceptable to the other IDiots.<br />
<br />
The new version goes like this .....<br />
<ol><li>You can have junk DNA because physical constraints and design compromises prevented a perfect design.</li>
<li>Due to genetic entropy the originally designed genomes might have degenerated.</li>
<li>Junk DNA could have been put in the genome by the intelligent designer as preparation for future creations.</li>
<li>Some of the junk DNA is redundant functional DNA that's present in case a gene breaks down.</li>
</ol>This new version of intelligent design is not in conflict with the presence of large amounts of junk in our genome.<br />
<br />
The evolution side should know about this new development just in case we're ever accused of not keeping up with the latest advances in Intelligent Design Creationism.<br />
<br />
<b>UPDATE:</b> Some readers are a little confused by this article. Of course there's no "new" version of Intelligent Design Creationism. Joseph's speculations are completely at odds with the views of the leading IDiots like Dembski, Myers, Wells, Behe etc. Most of the "leading lights" think there's a serious problem with junk DNA. According to them, ID predicts that most of our genome will be functional.<br />
<br />
The point of my article is that the IDiots never criticize or correct their friends no matter how stupid they get. That's why you won't see any proponents of intelligent design posting comments below that question Joseph's statements. <br />
<br />
BTW, Joseph, or Joe G, is a <a href="http://www.blogger.com/profile/08305194278121208230">field service engineer</a>. Please refrain from making unflattering comments about <a href="http://sandwalk.blogspot.com/2007/11/salem-conjecture.html">The Salem Conjecture</a>. (That's my job.)<br />

David Klinghoffer is at it again: <a href="http://www.evolutionnews.org/2011/11/how_ignorance_insulates_the_ne052731.html">How Ignorance Insulates the New Atheists</a><br />
<blockquote class="yellow"><i>First, that's because the key argument against belief in God lies, as it always did, in the attempted critique of the design argument. New Atheists like Richard Dawkins recognize this, and so does Coyne. Otherwise why would he name his blog, a venue overwhelmingly devoted to religion bashing, "Why Evolution Is True"? Yet the New Atheists have uniformly kept themselves just as ignorant of modern expressions of the design argument as they have of adult religious beliefs. When Dawkins goes after Darwin-doubters, he ignores -- will not debate, will not grapple with in print, probably doesn't even read -- proponents of intelligent design, a credible scientific alternative to and critique of Darwinian evolution. So too with Coyne. When Dawkins or PZ Myers or the rest does critique a Darwin doubter, it's always some hapless creationist, apprehended unarmed in the Internet wasteland and presenting a nice easy target. Like a schoolyard bully, they will pick on the little kids, but never on an opponent their own size.</i></blockquote>Aside from David Kinghoffer, I don't usually pick on hapless creationists. I'm more than happy to pick on the very best that Intelligent Design Creationism has to offer. Problem is, they don't listen to me.<br />
<br />
Is that because the IDiots prefer to attack the small fry rather than stand up to someone their own size (or larger)?<br />

<blockquote class="textbook">In every such society there is a cherished world of myth and metaphor which co-exists with the workaday world. Efforts to reconcile the two are made, and any rough edges at the joints are tend to be off-limits and ignored. We compartmentalize. Some scientists do this too, effortlessly stepping between the skeptical world of science and the credulous world of belief without skipping a beat. Of course, the greater the mismatch between these two worlds, the more difficult it is to be comfortable, with untroubled conscience, with both.<br />
<br />
In a life short and uncertain, it seems heartless to do anything that might deprive people of the consolation of faith when science cannot remedy their anguish. Those who cannot bear the burden of science are free to ignore its precepts. But we cannot have science in bits and pieces, applying it where we feel safe and ignoring it where we feel threatened&mdash;again, because we are not wise enough to do so. Except by sealing the brain off into separate compartments, how is it possible to fly in airplanes, listen to the radio or take antibiotics while holding that the Earth is around 10,000 years old or that all Sagittarians are gregarious and affable?<br />

<blockquote class-"brown"><i>The assumption that science decided to leave out questions of god, meaning, purpose and value is a caricature of the history of science, and Haught, who claims to be making a serious attempt to show the compatibility of science and religion, must know this. If he doesn’t, and he really thinks that science made such a decision — how does “science” do this, by the way? — then his misunderstanding of the relation of science and religion is total.<br />

When Haught turns around, then, and castigates Jerry by saying that everything that he said was a caricature, that every quotation that Jerry took from Haught’s work was taken out of context, and that instead of reading carefully and thoughtfully Jerry got his idea of god and theology from creationist websites, this was undoubtedly the most aggressive and impolite move of the whole debate. Listen to what he says:</i></blockquote><center><embed type="application/x-shockwave-flash" src="http://s0.videopress.com/player.swf?v=1.03" width="400" height="224" wmode="direct" seamlesstabbing="true" allowfullscreen="true" allowscriptaccess="always" overstretch="true" flashvars="guid=uhM1SIxI&amp;isDynamicSeeking=true"></embed></center><br />
Remember that John Haught is a Roman Catholic theologian. As far as I know he has never dissociated himself from the main teachings of the Roman Catholic Church. If he doesn't believe in any of the stuff that Jerry mentioned then isn't it up to him (Haught) to clarify what he does believe in?<br />
<br />
Does he believe in the resurrection? Does he believe that humans have souls? Does he believe in miracles? Does he believe that God answers prayers? Does he believe the Nicene Creed? Are all these things compatible with science?<br />

<br />
Nevertheless, from time to time Denyse comes up with a good example of IDiot thinking. A few days ago she asked the following question: <a href="http://www.uncommondescent.com/education/how-do-you-get-ideas-about-design-in-nature-across-to-people-who-are-not-learning-critical-thinking/">How do you get ideas about design in nature across to people who are not learning critical thinking?</a>.<br />
<br />
That's easy. You write books like <i>The Myth of Junk DNA</i>, <i>The Edge of Evolution</i>, and <i>Signature in the Cell</i>. Non-critical-thinkers just love that sort of stuff.<br />

When it comes to defending Intelligent Design Creationism, this is as good as it gets. <br />
<br />
Let me also remind you that <a href="http://www.discovery.org/p/209">David Klinghoffer</a> is a Senior Fellow at the Discovery Institute. When you see an article by a Senior Fellow on the Discovery Institute website, you just know it's got to be good.<br />
<br />
That's why I was so excited to see <a href="http://www.evolutionnews.org/2011/11/the_two_types_of_atheists052541.html">The Two Types of Atheists</a> on Nov. 3, 2011.  <br />
<blockquote class="yellow"><i>I meant to say that broadly there are two types of people who call themselves atheists but only one really deserves the dignity of the term. The first category -- the peasant, clod, village atheist, am ha'aretz -- is the person like Jerry Coyne with a cartoon version in his head of some one religion or all religions. He rejects the cartoon, figuring that as far as faith goes in general, he's got it all figured out and it's all nonsense. This type of person typifies the New Atheist movement. He has very little of interest to say.<br />
<br />
There's a second much rarer type, however, the person who has not only investigated at least one serious faith seriously but also experienced it, known believers, ideally was a believer himself at some adult stage of life. This person, in rejecting God, merits a real hearing.</i></blockquote>Aren't you glad that you can get the best of the best by just reading David Klinghoffer on <i>Evolution News & Views</i>?<br />
<br />
It amuses me to think of David Klinghoffer as an atheist in training. <div class="separator" style="clear: both;"><a href="http://1.bp.blogspot.com/-DgTWRNjhjcw/TrhFSayJBSI/AAAAAAAALs4/w-f8PjhNfTE/s1600/smile.gif" imageanchor="1" style=""><img border="0" height="15" width="15" src="http://1.bp.blogspot.com/-DgTWRNjhjcw/TrhFSayJBSI/AAAAAAAALs4/w-f8PjhNfTE/s200/smile.gif" /></a></div><br />

<br />
Joseph is the undergraduate winner of <a href="http://sandwalk.blogspot.com/2011/11/mondays-molecule-147.html">Monday's Molecule #147</a>. I'll be having lunch with him on Wednesday. If you have any other pictures of professors or hobos, you could post a link in the comments and I'll be sure to pass them long. (Joseph will probably read them anyway.)<br />
<br />
I'm thinking we could do a similar quiz for students&mdash;something along the lines of "university student or not?" There are plenty of pictures on facebook that professors could use.  <br />

Give me the complete, unambiguous, names of these molecules to win a free lunch. Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post <b><u>correct</u></b> answers to avoid embarrassment.<br />
<br />
There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.) Every undergraduate who posts a correct answer will have their names entered in a Christmas draw. The winner gets a free autographed copy of my book! (One entry per week. If you post a correct answer every week you will have ten chances to win.)<br />
<br />
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!) <br />
<br />
Name the molecules shown in the figure. Remember that your names have to be unambiguous. The best way to do this is to use the full IUPAC name but usually there are traditional names that will do. In this case there are trivial names for all of the molecules but make sure you have the stereochemistry correct.<br />
<br />
<i>New Rule:</i> In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.   <br />
<br />
<b>UPDATE:</b> Oh, oh. There's only one correct answer&mdash;congratulations Jason Oakley. I posted another answer that's almost correct (should be L-sorbose). All the rest of you need to review your understanding of <a href="http://en.wikipedia.org/wiki/Fischer_projection">Fischer projections</a>. Here's a hint: <a href="http://sandwalk.blogspot.com/2006/11/name-this-molecule.html">Name This Molecule #1</a>.<br />
<br />
<b>Winners</b><br />
Nov. 2009: Jason Oakley, Alex Ling<br />
Oct. 17: Bill Chaney, Roger Fan<br />
Oct. 24: DK<br />
Oct. 31: Joseph C. Somody<br />
