Better Biochemistry at EB2013

I've been talking to a lot of people here at EB2013 in Boston. One of the main topics of conversation is education in biochemistry and molecular biology. Another is blogs and social media. Some of these new friends are going to be looking at Sandwalk so I've prepared a short list of links on teaching biochemistry.

You can get updates on new posts on Twitter [@larryonsandwalk], on Facebook [Laurence A. Moran], and on Google⁺ [Laurence A. Moran].

Judging the Quality of MOOCs

Another journalist has written about Massive Open Online Courses (MOOCs). This one is in The New York Times: Two Cheers for Web U!.

Most of these articles about MOOCs are not very good but this one is different. The author expresses some skepticism and hit the nail on the head when he says ...

But the first thing I learned? When it comes to Massive Open Online Courses, like those offered by Coursera, Udacity and edX, you can forget about the Socratic method.

The professor is, in most cases, out of students’ reach, only slightly more accessible than the pope or Thomas Pynchon.

But that's not what I want to talk about today. I want to discuss the quality of these courses and how you might go about judging whether they are truly teaching the subject correctly.

Here's the problem. Too many people, like A. J. Jacobs, the author of today's article, assume that because the lecturer is famous or from a "top" school, the material must be accurate and up-to-date. As A. J. Jacobs puts it ...

On the other hand, how can I really complain? I’m getting Ivy League (or Ivy League equivalent) wisdom free....

With the exception of a couple of clunkers — my plodding nutrition professor might want to drink more organic coffee before class — most of my MOOC teachers were impressive: knowledgeable, organized and well respected in their field.

Students are not in a position to judge whether a professor is "knowledgeable" about the material being covered in a course. In the case of MOOCs, many students just assume that because the professor is from an Ivy League school then he/she knows how to teach an introductory course properly.

That's a very bad assumption as I've shown when I examined the biochemistry material being taught in the MIT courses Where Are the Best University Teachers?. Same is true for the courses at the Khan Academy.

I'm currently in Boston at EB2013 where I'm hanging out with biochemistry and molecular biology teachers and textbook authors. Many of these experts are not household names but they are the experts in their field, which is teaching. If you really want accurate information about the fundamental principles and concepts in biochemistry and molecular biology then you should take the courses they teach. You'll get a far better education than if you listen to professors from big-name research intensive-universities.

The recent ENCODE publicity disaster is just one example of the fact that top-notch researchers don't necessarily understand the fundamentals of subjects that are just outside of their own area of expertise.

Let's try and put a stop to this myth that the best teachers are professors from Ivy League schools. There's very little evidence to support that myth, especially in fields that I'm familiar with: evolution, biochemistry, and molecular biology,

Biology in Boston

I arrived in Boston, got settled in my hotel, and registered for Exeperimental Biology 2013.

My society is the American Society for Biochemistry and Molecular Biology (ASBMB). The main event tonight was the Herbert Tabor Research Award Lecture and the two awardees were ...

Ulrich Hartl Molecular chaperones in cellular protein folding mechanisms and pathways.

Arthur Horwich Chaperonin-induced protein folding.

This was followed by a reception featuring posters on outreach activity. It was fun talking to the poster presenters and seeing different ways of communicating science.


The photo below was taken from the convention center looking north at the World Trade Center. My hotel is the farthest one on the right of the main road going over the bridge. All the flags are at half-mast.

Coelacanths Evolve More Slowly?

I don't have a lot of time today (I leave for Boston tomorrow) but I can't let this pass.

The complete draft genome of the African coelacanth, Latimeria chalumnae has just been published in Nature (Amemiya et al. 2013). Ceolacanths have long been regarded as "living fossils," a term that persists even though the data have been disputed ever since the first fish were identified 75 years ago. I couldn't believe what I was reading when I saw the press release from the Broad Institute in Boston [Coelacanth genome surfaces]. The author, Haley Bridger of Broad Communications, says ...

An international team of researchers has decoded the genome of a creature whose evolutionary history is both enigmatic and illuminating: the African coelacanth. A sea-cave dwelling, five-foot long fish with limb-like fins, the coelacanth was once thought to be extinct. A living coelacanth was discovered off the African coast in 1938, and since then, questions about these ancient-looking fish – popularly known as “living fossils” – have loomed large. Coelacanths today closely resemble the fossilized skeletons of their more than 300-million-year-old ancestors. Its genome confirms what many researchers had long suspected: genes in coelacanths are evolving more slowly than in other organisms.

“We found that the genes overall are evolving significantly slower than in every other fish and land vertebrate that we looked at,” said Jessica Alföldi, a research scientist at the Broad Institute and co-first author of a paper on the coelacanth genome, which appears in Nature this week. “This is the first time that we’ve had a big enough gene set to really see that.”

Researchers hypothesize that this slow rate of change may be because coelacanths simply have not needed to change: they live primarily off of the Eastern African coast (a second coelacanth species lives off the coast of Indonesia), at ocean depths where relatively little has changed over the millennia.

This can't be right, I said to myself. Let's check out the actual paper.

Unfortunately, it was right. Here's the figure and here's what the authors say in the results section of the paper.

The morphological resemblance of the modern coelacanth to its fossil ancestors has resulted in it being nicknamed ‘the living fossil.’ This invites the question of whether the genome of the coelacanth is as slowly evolving as its outward appearance suggests. Earlier work showed that a few gene families, such as Hox and protocadherins, have comparatively slower protein-coding evolution in coelacanth than in other vertebrate lineages. To address the question, we compared several features of the coelacanth genome to those of other vertebrate genomes.

Protein-coding gene evolution was examined using the phylogenomics data set described above (251 concatenated proteins) (Fig. 1). Pair-wise distances between taxa were calculated from the branch lengths of the tree using the two-cluster test proposed previously to test for equality of average substitution rates. Then, for each of the following species and species clusters (coelacanth, lungfish, chicken and mammals), we ascertained their respective mean distance to an outgroup consisting of three cartilaginous fishes (elephant shark, little skate and spotted catshark). Finally, we tested whether there was any significant difference in the distance to the outgroup of cartilaginous fish for every pair of species and species clusters, using a Z statistic. When these distances to the outgroup of cartilaginous fish were compared, we found that the coelacanth proteins that were tested were significantly more slowly evolving (0.890 substitutions per site) than the lungfish (1.05 substitutions per site), chicken (1.09 substitutions per site) and mammalian (1.21 substitutions per site) orthologues (P < 10−6 in all cases) (Supplementary Data 5). In addition, as can be seen in Fig. 1, the substitution rate in coelacanth is approximately half that in tetrapods since the two lineages diverged. A Tajima’s relative rate test confirmed the coelacanth’s significantly slower rate of protein evolution (P < 10⁻²⁰)

The authors make it clear in the discussion that they think of molecular evolution of amino acid sequences only in terms of adaptation.

Since its discovery, the coelacanth has been referred to as a ‘living fossil’, owing to its morphological similarities to its fossil ancestors. However, questions have remained as to whether it is indeed evolving slowly, as morphological stasis does not necessarily imply genomic stasis. In this study, we have confirmed that the protein-coding genes of L. chalumnae show a decreased substitution rate compared to those of other sequenced vertebrates, even though its genome as a whole does not show evidence of low genome plasticity. The reason for this lower substitution rate is still unknown, although a static habitat and a lack of predation over evolutionary timescales could be contributing factors to a lower need for adaptation. A closer examination of gene families that show either unusually high or low levels of directional selection indicative of adaptation in the coelacanth may provide information on which selective pressures acted, and which pressures did not act, to shape this evolutionary relict.

This extraordinary claim flies in the face of everything we know about molecular evolution. Preliminary data from some of these same authors was criticized by Casane and Laurenti1 (2013) earlier this year. I'll quote what they said and leave it up to Sandwalk readers to draw their own conclusions.

Transposing the concept of ‘living fossil’ to the genomic level has led to the hypothesis of genetic stasis (or at least to the idea of a reduced molecular evolutionary rate) that is in sharp contrast with the principles of evolutionary genetics. Genomes change continuously under the combined effects of various mutational processes, that produce new variants, and genetic drift and selection, that eliminates or fixes them in populations. In other terms, the only possibility for genomes to replicate without change implies at least one of the two following conditions: (i) new variants do not appear (i.e. no mutations), and (ii) new variants are systematically eliminated by selection (i.e. no genetic drift and very powerful selection against new variants). Of course we can consider a less extreme case, i.e. a reduced evolutionary rate of the genome, but this still implies a lower mutation rate and/or stronger selection against new variants than observed in other species.

The coelacanth data make no sense. You should be very skeptical.

You should also wonder about the kind of people that Nature asks to review their papers. Reviewers may not be inclined to challenge the data but they should challenge the conclusions and they should ask the authors to address the fact that their interpretation is inconsistent with the modern evolutionary theory.

One other thing, if you look through the names of the authors, you will see several people who should know better than to attach their name to a paper like this. What's going on?

Ryan Gregory asked what he should do with his old conference name tags (on Facebook).

You hang them on your office door, of course. What else would you do with them?

Sometimes I wonder about those young professors. You have to help them with every little problem that comes up. Being a mentor is such a drag.

Darwin Doubters Want to Have their Cake and Eat it too

The phrase "to have your cake and eat it too" means that you can't have it both ways or "shouldn't try to have two incompatible things" [You can't have your cake and eat it].

The Intelligent Design Creationists are giving us a good example of just what this means. They have a new book coming out called "Darwin's Doubt." It's to be published by the religious arm of HarperCollins. The book will be available in a few months in the USA so the IDiots are ramping up the hype in preparation. We are told that this book, just like several previous books from the Discovery Institute, will definitively refute evolution and demonstrate the truth of Intelligent Design Creationism.

Here's how casey Luskin put it a few days ago [Three (or Four) Reasons Everyone Should Read Darwin's Doubt].

When published, Darwin's Doubt will be the single most up-to-date rebuttal to neo-Darwinian theory from the ID-paradigm. In this regard, one exciting element of Darwin's Doubt is that Meyer reviews much of the peer-reviewed research that's been published by the ID research community over the last few years, and highlights how ID proponents are doing relevant research answering key questions that show Darwinian evolution isn't up to the task of generating new functional information.

Here's how the strategy works. The IDiots are arguing the merits of Meyer's new book on the leading creationist blogs. They are generating lots of publicity and convincing their followers that the book is going to be a devastating rebuttal of "Darwinism." None of their followers have read the book but that doesn't matter. They won't have to.

How are scientist supposed to respond? None of us have read the book so we can't (yet) show that it is just more of the same old propaganda that we've seen before. What we can say is that we are very skeptical of the claims being made and we think it is disingenuous to promote those claims when we can't examine the "evidence." We can confidently speculate about what Stephen Meyer is going to say because he has a history and because he gives away some of his arguments in the publicity surrounding the book. The IDiots only sing one note and there's a very high probability that this isn't going to change.

That's exactly what Jerry Coyne said in his post: A (formerly) reputable publisher sells out to creationists. He puts it very nicely—and undoubtedly accurately— when he says, "But creationist Stephen Meyer, from the Discovery Institute, has apparently wrapped up the story. He’s hit upon the real reason for the Cambrian explosion: it’s intelligent design! Yes, baby Jesus made the phyla!"

Does anyone with an IQ over 50 think Coyne's prediction is wrong?

You know what's coming because we've seen it all before with the pre-publication hype for "The Myth of Junk DNA." "Science of Human Origins," and "Signature in the Cell." This time it's David Klinghoffer who is the designated whiner [Current Trends in Darwinian Book-Reviewing].

With a pub date of June 18, naturally no books are available. (Though you can preorder at a nice discount, for now, better than Amazon, over at DarwinsDoubt.com.) Nevertheless, at Why Evolution Is True, University of Chicago biologist Jerry Coyne assumes he knows what will be in the book. His absurd summary: "Yes, baby Jesus made the phyla!"

...

Darwinists have a curious way of responding to serious scientific and intellectual challenges to their beliefs. And it's getting more curious, isn't it? It's sort of evolving. If they had answers to ID's challenges, surely they would wait till they read the book, then accurately characterize what it says, and then tell us why Steve Meyer is wrong. But so far, and wasting no time, they have signaled in this strange prophylactic manner their unwillingness to do so.

The solution is obvious to everyone but the IDiots. Don't make outlandish claims about what's in a book until it's published and everyone can check for themselves. It you speculate about what the book is going to say then don't be surprised if others do as well.

You can't have your cake and eat it too.

Educating an Intelligent Design Creationist: Evidence for Junk

I'm replying to a post by andyjones (More and more) Function, the evolution-free gospel of ENCODE. That was the fourth post in an exchange between me and him. In response to his latest post, I'm working my way through five issues that Intelligent Design Creationists need to understand. So far, we've covered four of them.

Educating an Intelligent Design Creationist: Introduction
Educating an Intelligent Design Creationist: Pervasive Transcription
Educating an Intelligent Design Creationist: Rare Transcripts
Educating an Intelligent Design Creationist: The Specificity of DNA Binding Proteins
Educating an Intelligent Design Creationist: The Meaning of Darwinism

Intelligent Design Creationists have difficulty understanding the arguments for junk DNA and the evidence that supports those arguments. We try to explain the genetic load argument but it doesn't seem to penetrate. We try to explain that half of our genome is composed of defective transposons and viruses—often fragments of the intact genes. This doesn't phase them. And no matter how many times we describe the "C-value Paradox" and why junk DNA resolves the paradox, that evidence is ignored. We patiently describe the megabase pair deletions of the mouse genome and why this is evidence of junk. We teach them about copy number variation in the human genome and why DNA fingerprinting works. We show them examples of deletions and insertions in the genomes of different individuals telling them that these seem to have no effect as far as we know. We take time to explain modern evolutionary theory and why it is consistent with junk DNA. Finally, we describe our detailed textbook understanding of transcription and DNA binding proteins and they don't listen.

Andyjones says,

The fact that some very good scientists have not found functions for all of the genome does not negate the many functions they have found so far, for many classes of genetic element, including those commonly classed as ‘junk’. And they are still working. Part of the problem is this: if a layperson were to take apart a microchip, would he be able to discern the function of all the parts at the first attempt? Probably not. The problem is not lack of intelligence, but an early lack of understanding of the principles by which the thing is built. As soon as he understands a particular design principle, suddenly huge areas of the chip will be comprehensible to him. I humbly suggest that we have a number of such minor revolutions ahead of us in molecular biology. We are making great strides, but we do not yet understand all the principles of the transcriptome never mind the whole interactome. Perhaps there is more to learn about binding sites for RNAP? Or take pseudogenes: they have already been found to function in some cases as regulators, through their RNA transcripts interacting with real gene RNA transcripts. Then, alternative splicing is only partly understood. Who knows what other mechanisms operate at the RNA level? If you can’t imagine the function yet, it can be pretty hard to find it. But if one asserts there is no function (for example for rare transcripts) like Larry does, it will be even harder to find it.

This is a common theme among the Intelligent Design Creationists and, in fairness, among many molecular biologists. They think that junk DNA is simply an expression of ignorance. They ignore everything we tell them. They think that just because they don't understand something then nobody else does either.

In spite of what our opponents say, we actually have a pretty good understanding of the principles behind how a genome is built. Population genetics tells us that it ain't designed.

When I assert that rare transcripts probably have no function I'm not just talking through my hat and I'm not the only biochemist who says that. When I say that one million little bits and pieces of Alu SINES are very unlikely to have a function, that's not just idle speculation. When the ENCODE workers try to tell me that most of the genome is a huge web of 636,336 regulatory sequences, I can test this claim against the vast amount of information that we already know about genomes and transcriptional regulation and declare that this makes no sense. These are not arguments from ignorance.

Opponents of junk DNA are never going to be credible unless they tell us why the genetic load argument is invalid. They need to explain how their ideas comport with the data on genome size (The Onion Test). They need to explain why the average gene needs 5000 regulatory sites. They need to come up with a reasonable explanation for lack of sequence conservation. They need to tell us why the vast majority of defective transposons evolved a function.

Opponents of junk DNA need to address the arguments and evidence for junk DNA and stop pretending that those arguments don't exist.

Where Do Organisms Get Their Energy?

I've been thinking a lot about fundamental concepts in biochemistry. One of them has to be energy—where do cells and organisms get the energy to grow and divide?

Most of the metabolism section of biochemistry courses in North America are taught from an anthropomorphic, fuel metabolism perspective. That's understandable since the purpose of such courses is mostly to prepare students for the MCAT exam. (Medical school entrance exam.) I prefer an evolutionary approach to teaching biochemistry but that's not very popular these days.

By the time the course is over, students will have learned that humans get their energy from food, especially glucose. The next step is to ask where the glucose comes from. The simple answer is that food (i.e. glucose) comes from plants. The next question is where do plants get the energy to make glucose? The answer is, of course, sunlight. This should lead to an explanation of photosynthesis but that rarely happens in introductory biochemistry courses.

This description leads to the classic "food chain" as shown in the figure (above) from FT Exploring Science and Technology [The Flow of Energy Through Plants and Animals]. This is conceptually sound biochemistry as far as it goes. As long as students understand how sunlight can be used to make ATP and how ATP can be used to make macromolecules (including glucose), then they will understand that humans ultimately get their energy from sunlight. I would be happy if all biochemistry students could explain this food chain at the molecular level.

But in order to make sure that students really understand this process, I go one step further. I explain that there are many species of bacteria that are chemoautotrophs. Chemoautotrophs are incapable of photosynthesis yet they are able to grow and divide in the absence of any organic compounds. Their carbon source is CO₂, just like photosynthetic organisms. These bacteria have a basic metabolism that teaches us what primitive life forms must have been like. Knowing how they get their energy helps students understand evolution.

Where do chemoautotrophs get their energy? I'm interested in knowing how many readers have taken biochemistry and are able to answer that question. Please let me know in the comments before you read the answer in these posts [Carbon Dioxide Fixation in the Dark Ocean] [Core Concepts: Pathways and Transformations of Energy and Matter] [Ubiquinone and the Proton Pump].

Monday's Molecule #202

The last Monday's Molecule was the pyrrolysine, 23rd amino acid. The winner was Michael Florea [Monday's Molecule #201].

Today's molecule is an enzyme. Homologous enzymes are found in all species. They play an essential role in metabolism. The green part binds the substrate and the subsequent reaction reduces a bound FAD prosthetic group (yellow). Electrons are then passed to an FAD molecule in the purple part in the orientation shown on the left. Notice that the yellow FAD molecules are close together. (The two purple parts on the left should be joined but the connection can't be resolved in the structure.) This electron transfer results in a shift in conformation to the conformation of the purple structure shown on the right. Note that the FAD molecule has shifted to a less exposed position. The purple protein then dissociates and carries electrons to an membrane-bound enzyme that transfers electrons to ubiquinol (QH₂). Name the green protein and the purple protein.

This week I'm trying a new format in order to avoid moderating comments. Email your answers to me at: Monday's Molecule #202. I'll hold off posting your answers for 24 hours. The first one with the correct answer wins. I will only post mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

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 email message.)

Why Do We Do Science?

Lately there's been a flurry of activity in the American press about the value (or lack of value) of science. There have also been attempts by various organizations to enhance science education.₁ Most defenders of science and science education will eventually end up trying to explain how science directly benefits the economy, usually in the form of return on investment. In other words, we need to do science because eventually the result will be used by somebody to make a profit.

I posted an example of this a few days ago [Zack Kopplin Defends Science].

I think this is a dangerous strategy. There are several ways of responding to the "what's in it for me" question without bringing up indirect economic benefit. These strategies are common when defending public support for the arts, for example. They're also used when defending research in the humanities.

Phill Plait of Bad Astronomy hits the nail on the head as far as I'm concerned [Wall Street Journal Editorial Board Member Gets Schooled on Science Funding]. His defense of science should be the primary talking point whenever anyone questions the value of learning about the natural world. Here's what Phil Plait says in response to Zack Kopplin's "return on investment" defense of science when Stephen Moore asks why the government is funding research on sex in snails.

How’s that for return on investment?

And that’s just a pedestrian, look-at-what’s-directly-in-front-of-you kind of thinking. We research the Universe around us because we are curious, inquisitive, intelligent animals. We don’t know what snail mating habits might teach us. That’s why we study it. Maybe it’ll lead into insight on how animals behave, or a new chemical secreted during the process, or to insight on the environment where snails live. Maybe none of that.

But that’s not the damn point. We study science because we want to learn about the real world. If we wanted to stick our heads in the sand, as people like Moore would have us do, he wouldn’t even have the venue he has to say ridiculous things like he just did.

Science is about exploration and discovery, and making sure we don’t fool ourselves. It’s among the noblest of all human endeavors, and something we should be both pursuing to our fullest abilities as well as defending from those who would drag it down.

Right on, Phil! Science leads to knowledge and knowledge is always better than ignorance. That's reason enough to fund science research and reason enough to support science education.

As sure as night follows day, there are going to be comments from people who advocate the "return on investment" strategy for defending science research. The argument frequently boils down to the fact that most politicians don't care about knowledge. All they want to see is how science can help business or improve the health and physical well-being of our citizens. Because these politicians are ignorant of the real value of knowledge, we must cow-tow to their ignorance and defend science on their turf.

That's what's happening in Canada with our Conservative government. In my field (biochemistry & molecular biology), many of my colleagues think we have to justify our research by showing how it will improve health. The current buzzword is "translational research." If you don't engage in the kind of research that Conservatives want, then you won't get funded.

Unfortunately, that may be true in today's climate. That doesn't mean we have to fool ourselves into thinking that that "translational research" be our primary goal. We recognize that the ignorance of our Conservative government is a problem, not a virtue. It's a problem that has to be fixed ... in the long term. Our goal should be to educate the next generation of politicians so we don't have to be embarrassed by them in the future. Let's at least have some people like Phil Plait who will speak out for basic curiosity-motivated research. We'll never succeed in convincing politicians and the general public of the value of knowledge if we don't even try.

Let's make sure we start with our students. Let's at least ensure that when we have them in our clutches as undergraduates we make sure that they understand science and the importance of knowledge. If we don't do that then we have nobody to blame but ourselves when future societies demand that science generate a return on investment.

Looking at my own university, it's obvious that we are not doing a very good job in our courses. I fear for the future of science.

Wasting Money on the Jesuits at Regis College

Regis College is a Jesuit College at the University of Toronto. One of their main jobs is to train students for the priesthood in the Roman Catholic Church.

Earlier this year it offered a course on "Responding to 21st-Century Atheism." This attracted the attention of Huffington Post who published a story about it on January 27, 2013 [Regis College, Catholic Institution, Offers Course On Atheism]. This provoked some traffic in the blogosphere [e.g. Jesuit college teaches atheism!].

I thought this was pretty interesting so when Regis College announced a one-day workshop I signed up and sent in my $50. Yesterday I spent more than seven hours at Regis College: six hours of lectures and an hour to eat my peanut butter sandwiches.

Join Professors Scott Lewis, S.J., Gordon Rixon, S.J., and Jeremy Wilkins from the faculty of Regis College as they explore responses to the challenges presented by contemporary atheism. This one day seminar will discuss the role of Scripture, tradition, and theology to address the questions about human living posed by today's culture and climate of disbelief.

Soon to Be Released: Another Landmark for the ID Movement

I mentioned a few days ago that Stephen Meyer's new book Darwin's Doubt is about to be released [see Two Books on the Cambrian Explosion]. I'm planning to read it as soon as I can get a hold of a copy—probably sometime in August in Canada.

You are all going to have to read this book because, according to Casey Luskin, it is "going to be another landmark for the ID movement" [Three (or Four) Reasons Everyone Should Read Darwin's Doubt]. Luskin has read it. Here are his three reasons why the book is important and worth reading.

1. Arguments for intelligent design in the Cambrian explosion have certainly been made before. But Darwin's Doubt will be by far the most in-depth and mature development of those arguments to date, addressing in detail many ideas and rebuttals and theories advanced by evolutionary scientists, and showing why the theory of intelligent design best explains the explosion of biodiversity in the Cambrian animals.
2. When published, Darwin's Doubt will be the single most up-to-date rebuttal to neo-Darwinian theory from the ID-paradigm. In this regard, one exciting element of Darwin's Doubt is that Meyer reviews much of the peer-reviewed research that's been published by the ID research community over the last few years, and highlights how ID proponents are doing relevant research answering key questions that show Darwinian evolution isn't up to the task of generating new functional information.
3. As many ENV readers already know, we now live in a "post-Darwinian" world, where more and more evolutionary biologists are realizing that neo-Darwinism is failing, so they scramble to propose new materialistic evolutionary models to replace the modern synthesis. (These models include, or have included, self-organization, evo-devo, punc eq, neo-Lamarckism, natural genetic engineering, neutral evolution, and others.) In this regard, Darwin's Doubt does something that's never been done before: it surveys the landscape of these "post-neo-Darwinian evolutionary models," and shows why they too fail as explanations for the origin of animal body plans and biological complexity.

I know that it's a bit annoying to have to read all this hype when the book won't be available for several months. The Intelligent Design Creationists want you to know that any criticism of what they are saying about the book is unethical unless you've read it yourself. However, it's not the least bit unethical for them to make outlandish claims about what's in the book months before we can verify whether those claims are correct.

This is creationist ethics. It's not supposed to make sense.

Educating an Intelligent Design Creationist: The Meaning of Darwinism

Intelligent Design Creationists love to refer to their opponents as "Darwinists." We all know why they do it. It's a rhetorical device designed to belittle those who accept evolution. The term makes it look like evolutionary biologists worship a man who died 130 years ago and it implies that we still believe in nineteenth century science. The term "Darwinist" also makes it easy to associate modern scientists with social Darwinism. That's a common strategy employed by creationists of all stripes. I get it. It has nothing to do with scientific debates about evolution.

But sometimes rhetoric gets in the way of understanding. There seem to be a few (very few) Intelligent Design Creationists who genuinely want to understand the issues—even if their motive is still to push a scientific view of creationism. They pop up from time to time on the Intelligent Design Creationist websites. Andyjones seems to be one of them. (I'm giving him the benefit of the doubt.)
