Debating Darwin's Doubt

Today is the day that John Scopes was found guilty in Dayton, Tennessee (USA) 90 years ago. The Intelligent Design Creationists have marked the day with publication of a new book called Debating Darwin's Doubt [A Scientific Controversy That Can No Longer Be Denied: Here Is Debating Darwin's Doubt].

The book was necessary because there has been so much criticism of the original Stephen Meyer's book Darwin's Doubt. David Klinghoffer has an interesting way of turning this defeat into a victory because he declares,

... the new book is important because it puts to rest a Darwinian myth, an icon of the evolution debate, namely...that there is no debate, about evolution or intelligent design!

IDiot book by Stephen Meyer can't be refuted by scientists

The IDiots at the Discovery Institute have evolved something that they think is a winning strategy. They publish a book that has lots of scientific-sounding words then they embark on a massive publicity campaign to promote it as the latest scientific breakthroughs showing that evolution is wrong (and, therefore, God did it). Then they wait for the bad reviews to come in and concentrate on rebutting the reviewers. They get as much publicity by pretending that the reviewers are biased as they do from selling the books in the first place.

They use four main tactics to avoid admitting that they are wrong [see What Do You Do When All the Reviews Are Bad?]. One of them is to claim that all the reviewers are ignoring the main arguments in the book. That's what Stephen Meyer does in the video below. It's titled, "The Biggest Failure of Critics." (Warning, this has been tested with the Mark X Irony Meter and it passes. I can't guarantee that earlier models will survive.)

Stephen Meyer isn't keeping up

There are so many problems with Darwin's Doubt that one hardly knows where to begin. For me, the most important problem is that Meyer dismisses all the evidence for pre-Cambrian ancestors. These ancestors had most of the genes necessary to make all the animals that arose during the Cambrian explosion.

Our current model for evolution and development is that small changes in the regulation and timing of key developmental genes are responsible for big phenotypic differences, including new animal body plans. The data shows that all the animal phyla have similar genes and that there aren't very many genes whose origins can be traced to the Cambrian.

... those ignorant of history are not condemned to repeat it; they are merely destined to be confused.

Stephen Jay Gould
Ontogeny and Phylogeny (1977)This model was popularized by Stephen Jay Gould in his 1977 book Ontogeny and Phylogeny. Meyer disputes this model. He claims that massive amounts of new information (= new genes) arose at the time of the Cambrian explosion. He claims that this cannot be explained by any naturalistic means; therefore, god(s) must have made those strange Cambrian animals. (Presumably, the gods are also responsible for making them go extinct.)

Charles Marshall, a paleontologist at UC Berkeley (USA) wrote a critical review of Darwin's Doubt [When Prior Belief Trumps Scholarship]. Here's part of what Marshal wrote in September 2012.

Three Senior Fellows of the Discovery Institute Will Discuss Criticisms of Dawin's Doubt on a Radio Show on October 23

Evolution News & Views (sic) will bring together David Klinghoffer and Stephen Meyer to discuss Darwin's Doubt on the Michael Medved show [The Closing of the Scientific Mind: Join Us on October 23 in the Medved Studio for a Special Edition of the Science & Culture Update]. The topic is the "closing of the scientific mind," surely an appropriate topic for three men who are not scientists.

Does science open minds, or close them? A "scientific view" is frequently taken as being basically synonymous with skepticism, questioning, and independent thinking. All good and wonderful things! Yet very often, self-proclaimed paladins of "science" are impatient with genuine skeptics, flee from debate, or find a variety of other creative ways to avoid having to confront challenges to their beliefs.

In the special October 23 edition of the Science & Culture Update on the Michael Medved Show, you'll have a chance to talk about science and skepticism, closed minds and open ones, live in the KTTH radio studio, with Mr. Medved, Darwin's Doubt author Dr. Stephen Meyer, and Evolution News & Views editor David Klinghoffer. All three are Discovery Institute senior fellows.

For the discussion, they'll take as a case in point the critical reception of Dr. Meyer's book, Darwin's Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design, which has sparked furious debate -- and also a great deal of artful dodging of the relevant scientific issues by opponents of the theory of intelligent design. Why are critics of ID so determined to flee from a fair fight?

I think I'm going to try and listen in. I can't wait to hear how Medved, Meyer, and Klinghoffer respond to my scientific critique of Chapter 5: "The Genes Tell the Story?"

Molecular evidence supports the evolution of the major animal phyla

For those of you who are interested in the evolution of the major animal phyla, let me introduce you to the topic.

See the little red circle on the phylogenetic tree on the right? That's what we're talking about.

Most of the major animal phyla are first observed as primitive fossils in the Cambrian about 540 million years ago. The fossils cluster around dates that only span a few million years (about 10 million years). This is the Cambrian Explosion (see little red circle).

There's considerable debate among evolutionary biologists about what caused this relatively rapid appearance of diverse and disparate large fossils. Intelligent Design Creationist, Stephen Meyer decided that such a debate casts serious doubt on evolution as an explanation for the history of life so he wrote a book called Darwin's Doubt.

On spelling names correctly ... and irony

David Klinghoffer was recently aroused by a comment from me that was published on the Forbes website [Meet The Canadian Scientist Who Loves Battling American Creationists]. I said ...

Most scientists and science lovers cannot win a debate with the best intelligent design creationists ... That's because their knowledge of science is nowhere near as good as they think it is. One of the other reasons for debating creationists on my blog is to educate the non-creationists. I spend almost as much time criticizing fellow scientists as I do attacking creationists.

Naturally, David Klinghoffer thinks I was referring to him [University of Toronto Biochemist Admits Most ID Critics Can't Win a Debate with Us].

For the record, I don't think that David Klinghoffer is one of the best Intelligent Design Creationists. However, I stand by that statement as long as you understand that it refers to genuine debates.

Later on in his post, Klinghoffer criticizes me for spelling Ann Gauger's name incorrectly in one of the times I referred to her in a recent post. I corrected that typo. (I accidentally wrote "Guager.")

Klinghoffer refers to me as Lawrence Moran but my first name is spelled Laurence. (He can call me "Larry" if it's too difficult to spell Laurence correctly.) I note that he also spells my first name incorrectly in Debating Darwin's Doubt. (David Klinghoffer is the editor of that book.)

Klinghoffer adds ...

Leave aside the gratuitous reference to creationism, which Moran knows perfectly well that we don't advocate [see photo above] if he reads us as regularly as he seems to do [I do read them accurately, that's the problem], and if words have any meaning [the word "creationist" has meaning and Klinghoffer is a creationist]. Give him credit, though, for accuracy on this point: Most ID critics could not stand up in an encounter with an ID advocate like Meyer. You're right! I agree. They couldn't. Could you, Dr. Moran? That's something I'd love to see.

Well, David, you just might get your chance.

As you know, I posted a number of articles critical of Stephen Meyer's book Darwin's Doubt. Now that I have a copy of the book you edited, Debating Darwin's Doubt, I'm looking forward to all the rebuttals of my arguments that you included in that book. Here are my posts, in case you forgot.

• Darwin's Doubt: A Synopsis
• Darwin's Doubt: The Genes Tell the Story?
• The Cambrian Conundrum: Stephen Meyer Says (Lack of) Fossils Trumps Genes

• Stephen Meyer Says That Constant Mutation Rates Are a "Questionable Assumption"
• Stephen Meyer Says that "Homology" Is a Problem in Molecular Evolution

Oops, my quick scan of the book failed to find any mention of any of those blog posts! Damn. I guess Stephen Meyer and his creationist buddies are waiting for Debating Darwin's Doubt: Part Deux in order to address my criticisms. I'm a little miffed though, because the book tries to rebut other blog posts and it even addresses a different blog post of mine.

Stephen Meyer Says That Constant Mutation Rates Are a "Questionable Assumption"

Stephen Meyer is trying to make the case that the primitive animals of the Cambrian explosion really did arise suddenly as fully formed and distinct species. He says that the evidence points to God(s).

Scientists, on the other hand, have been exploring other possibilities and testing various models. They have shown that the molecular data is not consistent with sudden origins. Instead it shows that all of the major animal phyla are related and that their common ancestors probably lived millions of years before the Cambrian explosion. Thus, the evidence indicates deep divergence and the lack of transitional fossils does not prove the non-existence of these ancestral forms.

In order to support his creationist view, Meyer has to discredit the molecular evidence. We've already seen that he has five arguments against the data [Darwin's Doubt: The Genes Tell the Story?]. The first three were: (1) there are no transitional fossils [The Cambrian Conundrum: Stephen Meyer Says (Lack of) Fossils Trumps Genes]; (2) different molecular phylogenies do not agree in all detail [Stephen Meyer Says Molecular Evidence Must Be Wrong Because Scientists Disagree About the Exact Dates]; and (3) different genes evolve at different rates [Stephen Meyer Says Molecular Data Must Be Wrong Because Different Genes Evolve at Different Rates].

None of those arguments are correct and one of them (#3) is just plain silly.

Debating Darwin's Doubt: the prequel

I've had a chance to read most of Debating Darwin's Doubt and, as I mentioned earlier today, it doesn't address any of my criticisms. Here's the list of my blog posts ...

• Darwin's Doubt: A Synopsis
• Darwin's Doubt: The Genes Tell the Story?
• The Cambrian Conundrum: Stephen Meyer Says (Lack of) Fossils Trumps Genes
• Stephen Meyer Says Molecular Evidence Must Be Wrong Because Scientists Disagree About the Exact Dates
• Stephen Meyer Says Molecular Data Must Be Wrong Because Different Genes Evolve at Different Rates
• Stephen Meyer Says That Constant Mutation Rates Are a "Questionable Assumption"
• Stephen Meyer Says that "Homology" Is a Problem in Molecular Evolution

I'm really jealous because the IDiots spend a lot of time on Nick Matzke's blog post and on other posts.

I can only assume that they have no rebuttal. I know they read my blog and they should have been on the look-out for my critique in September 2013 because David Klinghoffer specifically challenged me to review Darwin's Doubt.¹ [On Darwin's Doubt, Still Waiting to Hear from Big Shots in the Darwin Brigade]. Here's what he said on September 4, 2013 just before I put up those posts.

Stephen Meyer Says Molecular Data Must Be Wrong Because Different Genes Evolve at Different Rates

Stephen Meyer is promoting the idea that God made all the various types of animals over a short period of time about 530 million years ago. The molecular data refutes that speculation because it shows that the various phyla share common ancestors and many of those ancestors appear long before the Cambrian Explosion.

This data creates a serious problem for the IDiots so they have to discredit it in order to dismiss it. As we've seen in earlier posts, Meyer argues that the molecular data is wrong because: (a) there are no transitional fossils, and (b) different molecular phylogenies do not agree in all detail [see The Cambrian Conundrum: Stephen Meyer Says (Lack of) Fossils Trumps Genes and Stephen Meyer Says Molecular Evidence Must Be Wrong Because Scientists Disagree About the Exact Dates]. He has five anti-evolution arguments altogether [Darwin's Doubt: The Genes Tell the Story?]. The third one is that different genes evolve at different rates.

Stephen Meyer Says that "Homology" Is a Problem in Molecular Evolution

Stephen Meyer argues (in Darwin's Doubt) that the Cambrian explosion cannot be explained by evolution but it can be explained by Intelligent Design Creationism.

His main thesis is that all the animals appeared suddenly in the Cambrian and there's no evidence that they arose from ancestors living earlier in the Precambrian. Unfortunately for him, there IS plenty of evidence in the form of molecular evolution. By comparing genes and proteins we can show that all the animal groups are related to one another and that their common ancestors are spread out over a considerable period of time as shown in the phylogenetic tree below from a paper by Dunn et al. (2008).

This evidence is a serious problem for Meyer so he has to deal with it in his book. He tries to discredit the entire field of molecular evolution by challenging the basic assumptions [Stephen Meyer Says That Constant Mutation Rates Are a "Questionable Assumption"], by setting up a strawman [Stephen Meyer Says Molecular Data Must Be Wrong Because Different Genes Evolve at Different Rates], and by pointing out that molecular dating is not precise [Stephen Meyer Says Molecular Evidence Must Be Wrong Because Scientists Disagree About the Exact Dates]. His most ridiculous argument¹ against molecular evolution is that the results must be wrong because there are no transitional fossils from before the Cambrian Explosion! [The Cambrian Conundrum: Stephen Meyer Says (Lack of) Fossils Trumps Genes]

None of those arguments stand up to close scrutiny but, as I warned you last week, there are actually five arguments against the validity of molecular evolution [Darwin's Doubt: The Genes Tell the Story?].

Are you ready for the final argument showing that molecular evidence must be discounted?

Stephen Meyer Explains Modern Evolution

 
The video below shows Stephen Meyer explaining evolution to the people who attended the Four Nails in Darwin's Coffin event at Southern Medodist University.

I'm posting this for my students in the class I teach on scientific controversies. One of the fundamental principles of any debate is to define your terms in a way that's intellectually honest and consistent. In the case of the creation/evolution debate, if there's actually a scientific controversy (there isn't) then everyone should be using the best scientific definition of evolution.

In his latest book, Signature in the Cell, Meyer refers to "modern" evolutionary theory as "neo-Darwinism." He never defines it but it's clear that he thinks of neo-Darwinism as the idea that mutation and natural selection are all there is to evolution. It's clear that Stephen Meyer has not read any modern textbook on evolution.

Watch the video and see how Meyer explains evolution to his mostly scientifically illiterate audience. At 6 minutes he says, "What we want to address tonight is the question of whether or not the principle neo-Darwinian mechanism of mutation and selection is sufficient to produce the forms of life that we see."

The scientific answer to this question is "no," mutation and selection are not sufficient. You also need random genetic drift, speciation, and geological events such as meteor impacts and ice ages in order to account for life as we see it today. (That's not an exclusive list, see Macroevolution.)

Meyer, and the next speaker, Richard Sternberg, are criticizing the ability of natural selection to explain the evolution of new forms in just a few million years. Most of their criticisms would apply to ALL explanations of evolution and not just those that rely only on mutation and natural selection but their arguments are much weakened by their lack of knowledge of modern evolutionary theory. It seems easy for them to knock down the strawman version of evolution that they don't believe in.

If there's a genuine scientific controversy here, you'll never learn about it by listening to these IDiots. However, it's worth noting that the quality of debate in the evolution/creation wars has improved considerably over the past thirty years. It used to be the case that any college student could instantly recognize the main flaws in the creationist position. Today, the average college biology student would have a great deal of difficulty debating Stephen Meyer, Richard Sternberg, Michael Behe, or Doug Axe. (Jonathan Wells? Not so much.) In part, that's because the average college student doesn't know enough about evolution. We aren't doing a very good job of teaching evolution.

Stephen Meyer lies about scientists working on evolutionary theory

I know Stephen Meyer and I have discussed his views on creationism many times. Some of the issues he raises are quite interesting and they aren't easy to refute. In this video from 2020, he presents two standard creationist objections to evolution: the Cambrian explosion, and the probability of evolving a gene.¹

Stephen Meyer "predicts" there's no junk DNA

Here's an interview with Stephen Meyer on the Evolution 2.0 website: Stephen Meyer Debates Perry Marshall – Intelligent Design vs. Evolution 2.0. I'm posting some remarks by Stephen Meyer in order to preserve them for posterity. Meyer should know by now that the evidence for junk DNA is very solid and the ENCODE declarations are wrong. The fact that he persists in spreading false information about the ID "prediction" is revealing.

Stephen Meyer Says Molecular Evidence Must Be Wrong Because Scientists Disagree About the Exact Dates

Stephen C. Meyer believes that the rapid appearance of complex, primitive, animals in the Cambrian cannot be explained without invoking God. The fact that there are no obvious transitional forms in the fossil record means, to him, that those transitional forms don't exist and God must have created all those primitive animals over a short period of time. Presumably, God then let them evolve naturally for the next 530 million years. (Meyer isn't very clear about this.)

Scientists looked at the molecular data in order to test the hypothesis that the Cambrian animals appeared suddenly in a very rapid radiation. The molecular data did not show such a rapid radiation. The overall pattern was consistent with branching evolution spread out over many millions of years. The diagrams that Meyer shows in his book are similar to the figure shown below from Erwin et al. (2007).

David Klinghoffer recognizes the problems with authorities and quote mining

We all know the drill by now. Intelligent design Creationists attempt to discredit evolution and science by pointing out what they see as flaws in basic theory. They also spend a considerable amount of time attempting to discredit individual scientists using guilt by association or direct character assaults.

One of their favorite tricks is to lift quotations out of context and present them in a way that makes it look like famous scientists are supporting Intelligent Design Creationism—or, at least, supporting the idea that evolution is flawed.

The tactic is so widespread and despicable that it led to formation of The Quote Mine Project
Or, Lies, Damned Lies and Quote Mines. That project ran out of steam about eight years ago because the authors just couldn't keep up with all the misinformation coming out of books, lectures, and articles from leading members of the Discovery Institute.

Stephen Meyer is a expert at this. Here are a couple of examples from his book Darwin's Doubt (2013).

What does Stephen Meyer really think?

One of the most frustrating things about the current crop of Intelligent Design Creationists is that it's impossible to pin them down on what they really think happened in the history of life. We know that some of them are closet Young Earth Creationists so we can guess what they think. They may be arguing that bacterial flagella reveal the actions of a designer but they actually don't believe any of the data used to make that argument. They think that all species (or kinds) were created at once just a few thousand years ago.

Other Intelligent Design Creationists seem to believe in a different form of creation but who knows what it is? Take Stephen Mayer, for example, you can read his books from cover to cover and still not know what he thinks about the history of life. It's clear that the Cambrian Explosion is a big deal for him and it's clear that he thinks god is behind it all but he's remarkably noncommittal about what actually happened according to his interpretation of the evidence.

ENCODE, Junk DNA, and Intelligent Design Creationism

andyjones has replied to my earlier posting on ENCODE and junk DNA. You can read his response at: (More) Function, the evolution-free gospel of ENCODE. Here's part of what he says ...

Larry Moran has sort-of replied to my previous blogpost but disappoints with only one substantive point. And even that one point is wrong: ID is not committed to the idea that individual genomes be well-designed; that is just an expectation some of us derive based on belief in a designer which is established on other evidence. ID would still be true if only globular proteins were designed (lookup Axe), or even if only the flagellum was designed (lookup Behe), or even if only the first life form was designed (lookup Meyer – and please read their actual work, not cheap reviews, because reviewers often dont pick up on the salient points – more below). I just say this lest readers get the impression that this is ID’s strongest point, or in any sense a weak point. It is neither.

It's true that there are some IDiots who are distancing themselves from a commitment to junk DNA. There are probably some who claim that they could live with the fact that 90% of our DNA is junk.

But let's not forget that Jonathan Wells is a prominent IDiot and he wrote a book on The Myth of Junk DNA. It sounded very much like Intelligent Design Creationism is staking its reputation on finding function for most of our genome.

Detecting God's Signature

Stephen Meyer has two main objectives. He wants to prove that Intelligent Design Creationism is the best explanation for the origin of information in the cell and he wants to prove that Intelligent Design Creationism is genuine science.

Let's look at the form of argument he uses in Signature in the Cell: DNA and the Evidence for Intelligent Design. This is from Chapter 17 where he's trying to refute the accusation that Intelligent Design Creationism is nothing more than an argument from ignorance.

... the argument made in this book ... takes the following form:

Premise One: Despite a thorough search, no material causes have been discovered that demonstrate the power to produce large amounts of specified information.
Premise Two: Intelligent causes have demonstrated the power to produce large amounts of specified information.
Conclusion: Intelligent design constitutes the best, most causally adequate, explanation for information in the cell.

Or, to put it more formally, the case for intelligent design made here has the form:

Premise One: Causes A through X do not produce evidence E.
Premise Two: Cause Y can produce E.
Conclusion: Y explains E better that A through X.

In addition to a premise about how material causes lack demonstrated causal adequacy, the argument for intelligent design as the best explanation also affirms the demonstrated causal adequacy of an alternative cause, namely, intelligence. This argument does not omit a premise providing positive evidence or reasons for preferring an alternative cause or proposition. Instead, it specifically includes such a premise. Therefore, it does not commit the informal fallacy or arguing from ignorance. It's really as simple as that.

Scientist are often accused of picking on the most idiotic of the IDiots and avoiding the really big guns who have all the best arguments for Intelligent Design Creationism.¹ See A Reason to Doubt the Real, Rather than Pretended, Confidence of Darwin Advocates, where David Klinghoffer asks,

How about answering the arguments of a real scientist who advocates intelligent design on scientific rather than Bible-thumping grounds -- a Douglas Axe or Ann Gauger, for example? How about a thoughtful critique of The Myth of Junk DNA or Signature in the Cell? A response to serious science bloggers like ENV's Casey Luskin or Jonathan M.?

So, here's my response to the very best that the IDiots can offer.

Premise One

Despite a thorough search, no material causes have been discovered that demonstrate the power to produce large amounts of specified information.

On the surface this looks like a purely scientific statement. I'm sure that most creationists accept it at face value since the leaders of the movement have been saying for years that evolution can't account for specified complexity or irreducible complexity.

Stephen Meyer is a philosopher but he's confident that his knowledge of biology is sufficient to establish the truth of this claim. He says on page 341 ...

Undirected materialistic causes have not demonstrated the capacity to generate significant amounts of specified information.

This is an important point since the logic of his argument depends on establishing that specified complexity can never arise from natural (materialistic) causes. You might think that a large part of this book would be devoted to backing up his premise. You would be wrong. Turns out, the real premise isn't exactly how it appears above.

Dennis Venema has written a critical review of Signature in the Cell and one of his criticisms is that there are many excellent examples of new information evolving by entirely materialistic mechansims that not violate the laws of physics and chemistry [Seeking a Signature]. We're all familiar with the examples of gene duplication and divergence but he might just as well have used dozens of other examples where specified complexity evolved. The wings of birds are for flying but they evolved from legs and fins. The irreducibly complex citric acid cycle evolved from simpler pathways.

These examples establish beyond a shadow of a doubt that there are perfectly reasonable, materialistic explanations for the evolution of specified complexity. That seems to negate Premise One.

Hang on. Meyer responds to the Venema criticism by pointing out that he was not referring to the origin just any specified information. He was only referring to the kind of specified information that appeared when life first formed. It's an origin of life problem.

The balance of [Venema's] review is spent refuting an argument that Signature in the Cell does not make and, thus, the evidence he cites is irrelevant to the main argument of the book; in short, Venema "refutes" a straw man. ... I happen to think -- but do not argue in Signature in the Cell -- that there are significant grounds for doubting that mutation and selection can add enough new information to account for various macroevolutionary innovations. Nevertheless, the book that Venema was reviewing, Signature in the Cell, does not address the issue of biological evolution, nor does it challenge whether mutation and selection can add new information to DNA. That is simply not what the book is about. Instead, it argues that no undirected chemical process has demonstrated the capacity to produce the information necessary to generate life in the first place. The book addresses the subject of chemical evolution and the origin of life, not biological evolution and its subsequent diversification. To imply otherwise, as Venema does, is simply to critique a straw man. [Stephen Meyer Resonds]

Meyer is correct. The book is about the origin of life and the problem of getting information into DNA 3.5 billion years ago, before there were cells, and before evolution. Meyer isn't always clear about this distinction but the argument that he frames above is about the origin of life.

Here's how he should have expressed Premise One ...

After decades of research, biologists have good explanations of how specified information can arise by evolution but they do not have a good explanation of how life began 3.5 billion years ago.

Premise Two

Intelligent causes have demonstrated the power to produce large amounts of specified information.

He's referring, of course, to the fact that bees make beehives and beavers make dams. There are hundreds of examples where animals produce complex structures full of specified information. That's what he means by "intelligent causes." All of this creation obeys the laws of physics and chemistry, therefore the explanation is entirely materialistic.

Don't forget that the argument is not about the creation of specified information throughout the history of life. It's about the ultimate origin of the information. Animals can create complex structures just as living cells can create new genes. What Meyer really wants to know is where do animals get this ability? Where did the information to create more information come from?

Animals evolved from more primitive ancestors. It's quite reasonable to postulate that all animals evolved from a common ancestor that had very rudimentary intelligence and that intelligence evolved from primitive neurons. Thus, the ability of intelligent animals to create complex structures—like pocket watches—ultimately traces back to the origin of life.

We can re-word Premise Two ...

Intelligent animals can produce large amounts of specified information by purely materialistic means. The ability to do this depends on the evolution of animals from the first living cells that arose 3.5 billion years ago.

Conclusion

Intelligent design constitutes the best, most causally adequate, explanation for the information in the cell.

This conclusion does not follow from either of the corrected premises.

Here's a better conclusion.

All of the information we see in biology, including the ability of beavers to make dams, can be traced back to the information present in the first cells. We don't currently have a good explanation for how DNA and cells arose.

It's difficult to see how you can squeeze a supernatural intelligent designer into this conclusion. Whenever we have good explanations for the origin of specified complexity, those explanations involve materialistic actions and not actions that require violation of the known laws of physics and chemistry. Beavers do not wave a wand to poof their dams into existance and bees don't get their beehives by praying for them

Therefore, it seems quite reasonable to assume that all examples of biological information arise by natural means, including the very earliest examples of DNA in the first cell.

(I don't address information theory, which takes up a significant part of the book for some unknown reason. See Jeffrey Shallit's take-down on Stephen Meyer in: More on Signature in the Cell.)

IDiot Irony

Sometimes I really wonder what goes on at the Discovery Institute.

As most of you know by now, Stephen Meyer has written a new anti-evolution book where he criticizes the expert scientific opinion on the Cambrian Explosion. He says that the experts are all wrong and the evidence shows that evolution is impossible. The only reasonable alternative is that god(s) made the primitive animals. Meyer has an undergraduate degree in physics and earth science (1981) and got a Ph.D. in history and philosophy of science ten years later (1991). He is not a scientist and he is not an expert on evolution.

Casey Luskin has a Master's degree in earth sciences but later on he got a law degree and he is primarliy a lawyer. He is not a scientist and he is not an expert on evolution.

David Klinghoffer is a writer. He is not a scientist and he is not an expert on evolution.

Nick Matzke is a graduate student who is finishing up his Ph.D. in evolutionary biology. He is a scientist and he is an expert on evolution. He is also an expert on Intelligent Design Creationism.

Nick Matzke wrote a long review of Darwin's Doubt—a book written by a philosopher [Meyer’s Hopeless Monster, Part II].

Casey Luskin, a lawyer, took it upon himself to critique Matzke's review [How "Sudden" Was the Cambrian Explosion? Nick Matzke Misreads Stephen Meyer and the Paleontological Literature; New Yorker Recycles Misrepresentation]. Luskin says,

Since Matzke published his review, The New Yorker reviewed Meyer's book. Gareth Cook, the science writer who wrote the piece, relied heavily on Matzke's critical evaluation, even though Matzke is a graduate student and not an established Cambrian expert. Cook uncritically recycled Matzke's claim that the Cambrian explosion took "many tens of millions of years," ...

Do you see the irony? Meyer is a philosopher and Luskin is a lawyer but poor old Nick is just a graduate student about to get a Ph.D. in evolutionary biology. Matzke is not an established Cambrian expert. Neither are Meyer or Luskin but that doesn't seem to stop them from criticizing Matzke and all other evolutionary biologists and all paleontologists.¹

David Klinghoffer just can't wait to contribute his two cents. Klinghoffer isn't a scientist and he certainly isn't an expert on paleontology but that doesn't mean he can't have an opinion [Regarding Matzke, Coyne, and Darwin's Doubt, a Reader Asks].

That is a good question. Casey Luskin has already demonstrated what a non-paleontologist Matzke is.

How could non-scientist Klinghoffer possibly know whether lawyer Casey Luskin had made a good case against evolutionary biologist Nick Matzke? Does Klinhoffer realize that Luskin is a lawyer, not a paleontologist?

Do you wonder why we call them IDiots?

1. My irony meter survived but it was touch-and-go for a minute or two.

You need to understand biology if you are going to debate an Intelligent Design Creationist

Last night's debate between Lawrence Krauss, Stephen Meyer, and Denis Lamoureux was very entertaining. I finally got to meet Stephen Meyer in person. (My photographer wasn't very good at focusing.)

There were some interesting exchanges during the debate. I want to talk about one of them.

Krauss tried to hammer Meyer on the "ID is not science" issue using quotes from a judge based on things said by lawyers in the Dover trial.¹ Krauss tried to dismiss ID by saying that it never makes predictions but Meyer countered effectively by pointing out that ID predicts that most of our genome is functional and claiming that the prediction was confirmed by the ENCODE study.

The ID position is that Darwinists predicted that our genome would be full of junk while Intelligent Design Creationists predicted that most of our genome would be functional. ID was correct and Darwinism was wrong, according to this story.

Both Lawrence Krauss and Denis Lamoureux accepted the "fact" that ENCODE was right and most of the DNA in our genome has a function. Krauss was also hampered by his misunderstanding of evolution. It's obvious that he accepts the Richard Dawkins view of evolution so he tried to accommodate the ENCODE results by saying it's what you would expect of natural selection. This is the Richard Dawkins position.

Krauss tried to downplay the issue by saying that ID had not predicted what those functional parts of the genome would be doing but this was a weak rebuttal.

The facts are these ....

• "Darwinists"—those who claim that natural selection is the only game in town—were opposed to the idea that most of our genome is junk. They still are.
• Today, the majority of experts believe that most of our genome is junk in spite of the ENCODE publicity campaign from 2012.
• The ENCODE Consortium has backed off it's original claim and now agrees that they misused the word "function." Some of them blame the media for distorting their position.
• The ID "prediction" has been falsified.

A competent biologist would have known all this and could have challenged Meyer's statement. A biologist would have then demanded that Meyer explain how a genome that is 90% junk fits with Intelligent Design Creationism.

I talked to Denis Lamoureux after the debate to let him know that he was wrong about ENCODE and he was very gracious. I promised to send him more information. A genome full of junk DNA poses no threat to his version of Theistic Evolution.

Lawrence Krauss is an expert on cosmology but he's very weak on biology. I know it's common for physicists to think they are experts in everything but that's just not true. It was demonstrated in last night's debate.

1. This is a bad strategy. It's better to accept that ID proponents are doing science but just doing it very badly. Meyer ignored the issue of whether ID counted as science. He just presented the scientific case for ID and forced Krauss to respond to his "evidence."
