Marty Pomeroy, advocate for anti-science

Echoed on the Panda's Thumb

A reader sent me a link to this horrid anti-evolution guest column in the MetroWest Daily News (I presume this is a suburban branch of the Boston Herald). It's appallingly bad, but so typical of the creationist strategy: fast and furious falsehood flinging, and the presumption no one will have the initiative or the ability to crosscheck the claims. It's also all stated in a pompous, self-satisfied style, as if the author knows more about biology than all those biologists out there…yet as becomes quickly obvious, the man knows nothing about genetics.

Well, I know a little about biology and genetics, and I'm willing to rip his dishonest essay apart, and there's always Mark Isaak's Index to Creationist Claims, which is a wonderful resource that makes it easy to tear into articles like this. It always surprises me, though, how unimaginative creationists are—it's always the same old bogus nonsense, repeated over and over again, with such oblivious confidence. Everything in Marty Pomeroy's essay has already been refuted.

First, here's the complete opinion piece.

Rescue science from evolutionists
By Marty Pomeroy / Guest Columnist
Wednesday, May 25, 2005

Those who think the "Intelligent Design" advocates are a bunch of religious whackos show that they have simply not looked into the issues being raised before the Kansas Board of Education.

Regarding evolution, there is much that classical evolutionary theory answers well, and much that it does not answer well.

Evolutionary theory proposes that there are two fundamental engines behind the advancement of species. The first engine is mutation, genetic change that can be passed on. This produces some difference in an organism that can be passed to its offspring, so the mutation must be present in reproductive cells.

The second engine is natural selection. This "selects" mutations that happen to be somehow "beneficial." The next generation has statistically more of the "chosen" genetic material because the gene provides some reproductive advantage. So those creatures with this gene produce more offspring, whether because of more aggressive mating behavior, resistance to disease, longer life -- anything that allows a species with this gene to reproduce more than those without it.

The theory goes that these two engines, over time, have produced all the biological diversity we see around us. Both these engines are absolutely necessary for evolution and work together. A simplistic summary would say that mutations provide the opportunity for advancement, and natural selection "chooses out" certain genes.

So what does evolutionary theory explain well? The concept of natural selection has become so well established by the weight of evidence that anyone who would try to argue against it will be shown foolish. It is impossible to ignore the variation of species over geographical areas, and the recognition that these variations have become established as adaptations to their environment by natural selection.

And where is the problem? It is in the concept of beneficial mutation. Natural selection is powerless if there is no new genetic material to work with. But that's where, in evolutionary circles, we instantly move from science to faith. In fact, there is no evidence for the existence of beneficial mutations in complex organisms.

With all the biologists observing life on this earth, there is not, at present, even a single example of a variation in a species that is replacing its peers due to some genetic advantage. Secondly, with all the bombardment of fruit flies with X-rays over the last 100 years, no new species of fruit flies has come about which is replacing the ones that have been around for ages. Lastly, looking in the fossil record, you cannot show any two species that have come from a common ancestor.

Now before anyone blows a gasket, it is obvious that mutations happen. Cancer typically results from mutations we do not want. Also at the viral level, changes (mutations) happen regularly. But the leap in complexity from virus to sexually reproductive mammal is too many orders of magnitude to make bold assumptions. In complex organisms, we simply don't have any examples of this taking place, and the fruit flies are still fruit flies.

The Sickle Cell Anemia gene in the malaria belt is sometimes used as an evolutionary example. It is an excellent example of natural selection taking a broken gene and, due to special circumstances (resistance to malaria,) selecting it out. But the sickle cell gene is not replacing the gene for normal red blood cells in general. When fully expressed, it is clearly not beneficial.

So beneficial genetic mutation lacks any scientific examples in higher species. This is one of the two foundational engines of evolution, and there is no science to back it.

Now this is not to say that Intelligent Design is the New Science. Rather, just like what is already being taught, it is an interpretation which, when applied to available data, provides an interesting perspective.

Still, those who despise Intelligent Design (like Bonnie Erbe) reject it less because they know much about it and more because they are fighting for their own faith in gradual naturalism and religiously refuse to consider evolution's glaring weaknesses (or because they simply dislike Republicans and their current supporters.)

So teach natural selection. But regarding the means for the advancement of species, we already teach one belief that is completely unsubstantiated. Why not teach two? They explain advancement differently based on differing assumptions (beliefs,) and both present interesting views of the data available. This would truly improve science education by separating facts from the interpretations which can so easily become dogma.

Note that Mr Pomeroy makes several strong claims here, all stated with extravagant confidence, and all completely false. They are trivially false, and easily checked against the resources at the talk.origins archive, which link to the scientific literature. Mr Pomeroy is claiming the absence of evidence from the scientific literature for certain phenomena, so it is fairly easy to refute him by finding just one counterexample; my links below generally point to whole lists of counterexamples.

  • "In fact, there is no evidence for the existence of beneficial mutations in complex organisms" and "So beneficial genetic mutation lacks any scientific examples in higher species"

    This is false. Mr Pomeroy mentions sickle cell anemia, but then mangles the story; that is a beneficial mutation in a specific context, the presence of high rates of malaria. It is his misfortune that he doesn't comprehend that evolutionary novelties aren't absolute good or evil; their function is relative and dependent on the environment. The Talk.Origins archive explains this, and there is a specific FAQ on known beneficial mutations. Even twenty-five years ago I did simple experiments in a cell biology lab to find mutant strains of bacteria that were resistant to antibiotics. Seriously, it happens every day, and it's easy to detect.
    There is also a good list of such mutations in a range of species, but Mr Pomeroy makes a peculiar demand for examples in "higher" species—would a list of beneficial mutations in humans do? I should mention that there is no qualitative difference between the DNA of E. coli and a human, and in fact, we share many of the same genes, so demanding examples in one but not the other is a bit strange.

  • "With all the biologists observing life on this earth, there is not, at present, even a single example of a variation in a species that is replacing its peers due to some genetic advantage."

    We have observed new species. But again, Mr Pomeroy inserts a peculiar restriction—that it be an example of a variation replacing its peers. I don't think he understands biology very well, because that makes the job even easier. I did a quick search of the literature, and found this example:
    Stolz U, Velez S, Wood KV, Wood M, Feder JL (2003) Darwinian natural selection for orange bioluminescent color in a Jamaican click beetle. PNAS 100(25):14955-9.
    The paper describes a particular color variant that is undergoing a selective sweep in Jamaica, a new allele that arose on the east side of the island and is spreading westward.
    This stuff is not difficult to find, if you know your way around the biological literature. Apparently, Mr Pomeroy does not.

  • "Secondly, with all the bombardment of fruit flies with X-rays over the last 100 years, no new species of fruit flies has come about which is replacing the ones that have been around for ages."

    Rhagoletis pomonella, the apple maggot fly. This is a serious pest that is currently undergoing speciation, with strains that are shifting from their native host, the hawthorne, to apples. I didn't even have to dig into the laboratory literature—this is happening naturally.

  • "Lastly, looking in the fossil record, you cannot show any two species that have come from a common ancestor."

    Ah, the hoary old "there are no transitional fossils" claim. Of course we can, and we have molecular evidence in addition to the fossil evidence. We can show linkage in the same way that paternity tests can reveal the relationship between a child and a presumed parent.

Mr Pomeroy made an accusation in his article that he applied to opponents of intelligent design creationism, but which applies more accurately to himself and his fellow apologists for creationism: of evolution, they "reject it less because they know much about it and more because they are fighting for their own faith". He is clearly ignorant of the biology he is describing.

Note the creationist pattern, though. Mr Pomeroy makes bold, confident assertions, each one dead wrong. If the average person were face-to-face with him, what could you say? It's not instantaneous to pull up references to refute such bald lies, and even here on the web where I can leisurely click on the talk.origins site and find orderly stacks of evidence, it takes time…time Pomeroy would use to move on to another lie.

So what do we do?

One counter-strategy is to reduce our position to a set of sound bites. That is not one of our strengths, sad to say: what the side of biology has is vast depth, and it always hurts to abandon that rich and complex resource and reduce it to simplistic assertions. But it's this simple: evolutionary biology has the mechanisms, the observations, the evidence, and the experiments that show that species are related to one another and diverged by the slow acquisition of genetic differences. When someone tells you that no new species have been observed, that mutations can never benefit an organism, and that there have been no transitional forms between species, he's flouting the facts and is simply lying.

Another is to slam the promulgators of such nonsense as Pomeroy's. That essay was a parade of ignorance; Marty Pomeroy has destroyed his own credibility on the subject of evolutionary biology. That is a point that should be hammered in every time he takes pen to paper in the future. Marty Pomeroy has no knowledge of biology and has a history of making stuff up about the subject, and his opinion on evolution should have no weight.

One other thing we have to do is take this message home to the media. Certain right-wing weblogs are fond of the idea that their role is to fact-check the "MSM" (mainstream media) (ironically enough, that's from a site that has also peddled the anti-evolution snake oil), so let's do it. Send short letters to newspapers that publish creationist tripe, and don't let this BS slide by. For instance, you can send letters to the MetroWest Daily News at mdnletters@cnc.com. Tell 'em what you think, in a polite way. Here's mine:

I was surprised to see the guest column by Marty Pomeroy ("Rescue science from evolutionists" on 25 May 2005) in your paper. You see, I'm a biologist by profession, and all the things that Marty Pomeroy declared were not in the scientific literature, such as evidence of beneficial mutations, replacement of alleles in populations, or transitional forms, actually ARE extensively documented in the scientific literature. It was rather like reading an article in which someone confidently asserts that not only are penguins nonexistent, but that no one has ever photographed or captured one. It's a silly claim that can be refuted by simply showing the person a photograph or taking them to the zoo, so this kind of thing is most disconcerting to see published in the 20th 21st Century, in a nation that should be well known for its scientific accomplishments.

Mr Pomeroy is obviously not at all familiar with the scientific literature despite his bold declarations about what is not in it. I suggest that he try reading an introductory text in population genetics, or that he browse through a few issues of Nature or PNAS or any of the many journals at his local university library. Barring that, I've provided a summary of the evidence that counters each of his claims at http://pharyngula.org/index/weblog/comments/marty_pomeroy.

And please, readers of the MetroWest Daily News, do not take anti-scientific crackpottery like that of Mr Pomeroy seriously.

Write your own, leave them in the comments here. One thing we might want to think about is developing a library of pithy rejoinders to complement Isaak's wonderful index; we've got the data, but what we also need are strong, short statements that make the emotional and rhetorical case.

And I know I'm a long-winded SOB, so I'm not the best to compose them.

BlastfromthePast claims that the authors of the article about the Jamaican click beetle <blockquote>have no idea what advantage this different coloration represents</quote>.
This is a misreading. The advantage is always that of having more offspring. The question is always how some change e.g. in the genes leads to having more offspring. When examining some change that has led to more offspring, we can therefore say that the change is the advantage in thid particular case (and only in this case).



#26268: — 05/27  at  03:42 AM
The absurdity of armchair anti-evolutionists is amazing. The logical extension to the opinion of people like Pommeroy would be to call for the sacking of evolutionary biologists. After all, if those biologists are so deluded or stupid that they accept a biological theory easily debunked by a layman then they must be incompetent.



#26269: — 05/27  at  03:44 AM
Your "list of beneficial mutations in humans" is a list of variations.


What the hell is mutations other than variations? If someone has a new blood type, it doesn't eman that it's completely different from the existent bloodtypes, it just means that there are some variations over the general theme.

Mutations that turn you into a x-men like mutant is hardly what one would expect outside the world of comics.

I can't believe Marty blew off the examples of beneficial mutations in higher organisms, like the ability to metabolize lactose and the CCR5delta32 mutation, which makes humans who have it very resistant to infection by HIV. I don't think he truly read any of the responses. Certainly he ignored that which he did not agree with.

I don't think he truly read any of the responses. Certainly he ignored that which he did not agree with. He clearly doesn't understand what a mutation is! For example, the CCR5delta32 mutation, if I recall correctly, is a single base substitution that results in a stop codon and a truncated protein.

Sorry for the double post. It comes from hitting the "submit key" twice in impatience, I guess.

As for the "Holocaust denier" remark, although one can make a case for ID being much like Holocaust denial, I rarely make that comparison because it is so inflammatory. Yes, ID advocates and Holocaust deniers use similar logical fallacies and misrepresentation of the data to support their pseudoscience or pseudohistory, as the case may be. However, I like to think that most ID advocates are not fascist apologists or anti-Semites, as Holocaust deniers are. Bringing up the Holocaust denial comparison, even when appropriate simply on their using similar methods of distorting and denying data, is, in essence, the same as calling someone a Nazi, which is why I only bring up such comparisons with great trepidation and then with a great deal of explanation.

Faith is for religion and that's exactly what the Darwinian narrative has become.

Thanks for playing. There's a consolation prize waiting as you exit stage left. It's a copy of Origin with the parts in chapter's 1 and 5 where Darwin professes his belief in the heritability of acquired characters highlighted for the reading impaired.


DaveScot, you're right about the Darwinian narrative becoming a faith. However, it's not scientists who treat Darwinism as a religion, but rather people such as yourself. Science, done right, does not rely on authority, but on theories that convincingly explain the facts, and such theories must be falsifiable. The theory of evolution does not succeed or fail because of what Darwin said.

Religion, including ID, is not falsifiable. In place of theory they say goddidit or the iddidit. Sure, Darwin made some mistakes. He's not God. Science has moved on in the last 150 years.

Actually, if you want to regard Darwin as a rival God, that's alright with me. But keep your religion out of science classes in public schools.

Mr Pomeroy:

People question your ethics because you did something dishonest. In you article, you claimed that a number of things were absolutely not documented in the scientific literature. That was false. Now you claim that you have read through the talk.origins site; if that is the case, then the ignorance excuse is off the table and we're left with nothing but incomprehending stupidity, or willful dishonesty. Which is it?

All your comment here is is an attempt to backpedal and weasel. This is an egregious example:
It’s my paragraph in the middle that requires the most explanation: “With all the biologists observing life on this earth, there is not, at present, even a single example of a variation in a species that is replacing its peers due to some genetic advantage.”
Damn. That was way too concise and in retrospect should have been stated differently. With all the variations, obviously some are taking over. What I am looking for is a species which clearly does NOT have some trait anywhere, a new trait arises, and it has enough of an advantage to work it’s way through the entire population. That would be a scientific proof. Still looking. Not closed minded, as you have assumed.


The Jamaican beetle example I gave represents exactly that: evidence for the gradual replacement of one allele by another, caught in the act. And it is not unique; on the first page of a pubmed search I also found this and this and this and this. Moving the goalposts is a standard creationist tactic, though, so I'm not at all surprised to see you doing it.

Oh, and here's a hint: people who talk about "scientific proof" don't understand the scientific method.

Well put, zilch. You bring up what I think is the real problem -- high school science classes ARE just lectures of "facts," many of which ARE false, and all of which are just stated. When support is given, it's often support that most high school students can't understand. With the massive amount of shitty textbooks and shitty teachers out there, I can understand why someone who's only experienced a high school biology class would doubt what they're told, and I respect that.

What's bizarre is when the people who don't believe what they're told in biology class lose their healthy skepticism when confronted with ID, which makes far less sense and for which there is much less evidence. I guess connecting the development of the species to God adds it to the giant web of things that you Do Not Question.

Looking at the biological evidence one would have to say that any "designing" was done by some incompetent, clueless, on-the-job committee of designers working in all sorts of random directions without any real understanding of what they were doing and often undoing each others work. Strangely enough this is exactly the characteristics which would be expected of a planet's worth of unintelligent self-replicating molecules... No wonder the IDers try not to look.

Of course it also fits perfectly with the concept of Unintelligent Design! grin

Thanks, DaveScot, for the fine example of how evolution is a scientific theory and not a matter of faith! If scientists were driven by a dogmatic faith in "Darwinism," as IDers claim, then they would still be professing that acquired characters are inherited (or at least have had a major schism over it), since that's what the prophet said. Instead, since further research didn't support that conclusion, it has been thrown out as Darwin's hypotheses have been refined into the modern scientific theory of evolution.



#26294: — 05/27  at  09:31 AM
I've gone over that arbitrary 300 word limit of course. So presumably that means the reporter types feel free to ignore everything I've said. It's hard to imagine them learning anything of merit, complete with multiple independent lines of supporting evidence, in less than 300 words though. That must be why they are only reporters and IDers. Their brains glaze over long before they can read/see enough evidence to spot the pattern.


Just to clarify:

(1) Marty Pomeroy does not appear to be a reporter or a journalist of any kind.

(2) Reporters don't decide which letters appear in newspapers -- editors do.

(3) It is a non sequitor to say that "reporter types" (whatever that is supposed to mean) will ignore anything longer than 300 words.

(4) You have no grounds for conflating reporters and IDers.

(5) Many journalists are well educated and read voluminously.

(6) The reason for a 300-word limit on letters to the editor should be fairly obvious on a moment's reflection: newspapers receive sacks of letters that must compete for limited space.

Now please return to your regularly scheduled feeding frenzy.



#26295: — 05/27  at  09:49 AM
"Your 'list of beneficial mutations in humans' is a list of variations."

Ah, so when a beneficial trait appears it's merely a "variation", but when a negative trait appears it's a "mutation". That simply doesn't fly.

This seems to make the implicit assumption that there is some allelic variation that has always been present (if hidden) in current species that did not arise in a mutational event. Maybe Herr Pomeroy *is* starting from an alternate hypothesis about the origin of species, despite claims to the contrary.

Prediction: Pomeroy will go the Spetner route on beneficial mutations (e.g. "No beneficial mutations have been found. Well, beneficial mutations have been found but they're not the type that evolution requires". -- Oops, looks like DaveScot beat him to the punch).



#26296: — 05/27  at  10:06 AM

That would be a scientific proof. Still looking. Not closed minded, as you have assumed.</blockquote>

So Mr. Pomeroy, we need to sequence the genome of every single organism in a metazoan species, wait a while (several thousand generations?), and the resequence all their children to see if a new mutation has spread through the population that produces beneficial trait?

Is that all you want? That's not being closed minded, that's just being unrealistic in advocating for and experiment that is technologically impossible to perform.

Really, this stuff has been repeated tens, if not hundreds of time on the talk.origins forum.



#26297: — 05/27  at  10:09 AM
Mr. Pomeroy, just what is it that you think separates you from a Holocaust denier?

By the reading of this and other articles, it looks this is where the debate is leading.



#26301: — 05/27  at  10:28 AM
I think his point that "Your "list of beneficial mutations in humans" is a list of variations." is that we cannot prove that these are actually mutations - they may have always been in the population. The apolipoprotein, existing in a small community seems like a very good candidate for a mutation, but how this can be "proved" to be so, I am not sure.
Clearly, the article was badly written and poorly thought out, but some parts of it may be technically true "Lastly, looking in the fossil record, you cannot show any two species that have come from a common ancestor." is another example. While it may be possible to say two species came from a common ancestor, if people choose not to believe this, it can't really be proven



#26302: — 05/27  at  10:31 AM
There is data, and there is the interpretation of data.

Pomeroy's ignorance extends to grammar. There are data.

By the reading of this [Pomeroy's ID equivalent to Holocaust denial] and other articles, it looks this is where the debate is leading.


Characterizing Pomeroy's assault on science and his warm reception here as a debate would imply that reasonable people may disagree on this issue. We don't. There is no debate, no controversy, no reason to accord such a position as Pomeroy's even token civility.

ID and its equivalence in form and reputability to Holocaust denial, AIDS denial, Moon Landing denial and etc., is where Pomeroy's waste of time starts, not where it leads.



#26311: — 05/27  at  11:08 AM
Hey, Pomeroy. You need a trait that arose by mutation and is now dominating a population where it didn't exist before?

Check out mosquitoes and the nifty mutation they got that allows them to digest DDT.

It fits your bill exactly, Mr. Pomeroy.

Now that all your objections have been answered . . . well, what would Jesus have done?

To davidm:

1. What are the chances of becoming an editor without first going through the reporter stage?

2. Where's the rule that says all my remarks had to be directed at Mr.Pomeroy? That section was clearly marked as about reporter types and IDers. It's not that difficult to understand for anyone with the ability and willingness to comprehend English.

3. I don't have to conflate IDers with reporters. I listed them as a separate group. It is already well-established that the rank and file IDers are limited by sound-bite mentality - hence the earlier call for some sound-bites on the pro-science side. So I was actually being rather generous to the IDers by including them at all. A 300 word limit would seem to be rather high for many.

4. Do you have any evidence for your hypothetical well-read reporters (and their prevalence)? Not that it's particularly relevant to any of the points anyway.



#26317: — 05/27  at  11:41 AM
Jeff,

By the way, I think the decision in Times v. Sullivan suggests that newspapers would have some liability were they to publish clearly libelous stuff, even on an op-ed page.

Certainly a newspaper has some obligation to not print material that is wholly wrong, or just completely useless.

My point exactly, thank you Ed. My letter was directed to the editors of the paper, not its readers -- I honestly hadn't given a thought to having it published.

A columnist is entitled (obligated, actually!) to write their own opinions, but as someone else said, they are not entitled to their own facts. What disappoints me about the article is not that it was written, but rather that it was published.

I do appreciate Mr. Pomeroy coming here and attempting to further explain his opinions; not many would do so in what is clearly a hostile environment. So thank you for that, sir, I sincerely appreciate the effort.

Having said that, I still cannot condone an editor passing through what are clearly factual errors without comment. I understand their readers are at a third grade level, but I would hope the editors themselves are not.
