How Do You Describe This Weird Bacterium?

Not With Evolution

The reason why evolutionists use teleological language is simple and, no, it isn’t because they are lazy. Evolutionists use teleological language because otherwise biology doesn’t make sense. That was evident again this week when the unusual cell division of a bacterium that lives on the marine nematode, Robbea hypermnestra, was reported.

The easiest way to cut a hotdog in half is by slicing it in the middle. And that is how bacteria usually replicate. A protein ring is formed in the middle to start things off, though there are many variations on just how that is done. From there, an immensely complicated molecular choreography proceeds to divide the unicellular organism into two daughter cells.

But the R. hypermnestra symbiont breaks the rule by dividing long-ways (see photo), and without the customary protein ring. This longitudinal division makes sense because these bacteria live, like the hair on your head, with one end attached to the nematode. Attachment to the nematode is important, and longitudinal division leaves the two daughter cells both attached. Transverse division would leave the far daughter cell floating free.

But from an evolutionary perspective this makes no sense. Aside from the fact that the cell division process is statistically impossible for random mutations to construct, evolution calls for designs to be inherited via common ancestry.

But what biology reveals—and the R. hypermnestra symbiont is yet another example of this—are one-off designs. Biologists even have a name for this general trend: “species-specific” biology.

This makes no sense on evolutionary theory and the inevitable result is Aristotelianism. As usual, it is the infinitive form that reveals all:

The division of the R. hypermnestra symbiont leaves the dazzled scientists at a loss to know which kind of evolutionary advantage this quirky division might bring. One possible explanation is that this would allow the symbiont to remain faithful to its worm host. “Longitudinal division might have evolved to transmit host attachment to both daughter cells. In other words, to avoid that one daughter cell is lost to the sand or the sea,” speculates Bulgheresi.

Teleological thinking is not a sign of laziness, it is a sign of a failed theory that lacks explanatory power. Biology does not lend itself to evolutionary explanation and language.

Religion drives science, and it matters.

Professor B Supports Evolution

It’s Not My Dog, He Didn’t Bite You, And Besides You Kicked Him First

In this age of specialization we look to the experts to tell us what to think. And when it comes to origins, the experts tell us that life evolved. Random mutations, surprisingly enough, are sufficient to create the species. As if we needed another example of this, we now have “Professor B,” who wishes to remain anonymous but can’t help to explain that skeptics of this modern day Epicureanism are “almost certainly wrong” to doubt that proteins can spontaneously arise because it would require something like 10^74 attempts. After all, that figure was “based on a very small sample.” Small sample? If the professor understood statistics he would know small sample sizes do not invalidate results—not to the level he requires. In fact, as we have discussed many times, several studies have arrived at this type of astronomical figure.

When presented with that inconvenient fact, our Professor B switched strategies. Now, it seems that, according to the professor, “a very large number of different amino acid sequences were capable of performing the same biological function.” Therefore it is not a big problem for evolution to create these incredible molecular machines.

That is an absurd misrepresentation of molecular biology. While it certainly is true that a large number of different sequences can perform the same function, we are nowhere close to 10^74. “Very large” in this context is astronomically smaller than 10^74.

As if sensing a problem, Professor B switched to yet another tactic, claiming that evolution is capable of creating astronomical numbers of proteins anyway. It seems, according to the professor, that evolution can rip through 10^42 different proteins in search of what works.

Not that this helps much, as 10^42 is still dozens of orders of magnitude smaller than the needed 10^74. But even the estimate of 10^42 is, itself, absurd. It comes from a paper that assumes the pre existence of bacteria and, yes, proteins. In fact, the evolutionists assumed the earth was covered with bacteria, and each bacteria was full of proteins. That of course is not an appropriate assumption for the question of how proteins could have evolved in the first place. In fact, it is circular. Good thing the professor remained anonymous.

BioLogos and Vitellogenin Genes

This Problem Does Not Easily Go Away

Recently I have been responding to several articles by evolutionist Dennis Venema. Venema has made various arguments about how genetic evidences strongly support evolution and I have provided rebuttals to those claims. For instance, I explained here that while Venema discusses evidences that are consistent with evolutionary expectations, he does not list or mention the substantial body of scientific findings that are inconsistent with evolution. This is a problem with the evolution literature: the scientific evidence is too often selectively presented. In fact, I have often seen evolutionists claim that there are no contrary evidences, and that the science fully backs evolution. This sort of confirmation bias presents a roadblock to meaningful discourse on the topic of origins.

Next Venema focused his claim on the specific case of human evolution, and the similarity between the human and chimpanzee genomes. Again, Venema made high claims about the evidence. He concluded: “These observations strongly support the hypothesis that our species arose through an evolutionary process.”

But, in fact, as I explained here, there are several significant problems with this claim. For example, the chimpanzee and human genomes have differing patterns that do not fit evolutionary expectations. There is also a big difference between viruses in the genomes of humans and the other primates. Again, these differences do not fit the expected evolutionary pattern. Furthermore, the chimp-human genome beneficial differences are few and appeals to alternate splicing differences (another big difference between the genomes of humans and the other primates) to evolve humans lead to astronomically improbable pathways.

As always, I explained that the point is not that evolutionary explanations are not possible. Speculative explanations are always possible. Perhaps evolution did this, perhaps it did that. But that does not change the fact that the primate genomes do not “strongly support the hypothesis that our species arose through an evolutionary process,” as Venema and the evolutionists claim.

Next Venema focused even more narrowly on a particular genetic detail: human chromosome two, which he presented as a powerful example of an evolutionary confirmation. And yet as I explained here, not only did Venema not mention several scientific problems with his claim but the claim, even if true, would not demonstrate evolution as evolutionists claim. There is no evolutionary relationship revealed. Even if evolution were true, these data would give us no evidence for it. What was disturbing about this example was Venema’s recounting of a deceptive lecturing strategy he uses in presenting this topic in his class.

Next Venema presented pseudogenes which Venema argued are powerful and compelling evidences for common descent. It is, explained Venema, “one of the strongest pieces of evidence in favor of common ancestry between humans and chimpanzees (and other organisms).” And again, I explained, here and here, that there are several, fundamental, problems with this evolutionary claim.

In this case, however, Venema discussed his underlying religious belief that this evidence is a problem for creationism type theories. Venema was highlighting one of the important beliefs at the foundation of evolutionary thought. This belief, if true, does indeed require evolution to be true. But of course it is not falsifiable.

Vitellogenin genes

Now we move on to Venema’s next topic, the vitellogenins. Vitellogenin genes are found in a wide range of species and, like most genes, perform multiple functions including helping to provide the nutrients in egg yolks. Also like most genes, the pattern they form amongst the species does not always correspond very well to the expected evolutionary pattern. Of course there are always explanations, and evolutionists draw upon a variety of mechanisms, including lineage-specific events, to explain the vitellogenin genes.

For example, this paper focuses on mosquito vitellogenin genes. It concludes that the genes arose by a series of duplication events, and that the pattern of duplication was different in each mosquito genus. The paper also uses purifying selection, gene conversion, unequal crossover, and concerted evolution to explain the observed pattern of the mosquito vitellogenin genes, and concludes that these mechanisms must have also worked, independently, in other invertebrate species, and vertebrate organisms as well.

Similarly, this paper examines the evolution of vertebrate vitellogenins and also draws upon a variety of events and lineage-specific mechanisms. As I have discussed many times, while the basic idea of evolution is that the species share common designs as a consequence of common ancestry, in fact biology is loaded with unique, one-off designs for which evolutionists need to appeal to “lineage-specific” evolution. Consequently evolution can explain a wide variety of observations and patterns, and this applies equally well to the vitellogenins.

Clearly evolutionary theory is fine with a range of patterns when it comes to the vitellogenins. Of course this is true for molecular, and morphological, designs in general, as we have seen many times. Designs can fall into an evolutionary common descent pattern, or not.

The advantage of this flexibility is that evolutionary theory can explain a wide range of observables. The disadvantages, however, are many. The theory becomes less parsimonious. It becomes more resistant to falsification. And it loses its evidential arguments. If a theory can explain A, and B, and C, … and so forth, then the finding of A is hardly compelling evidence for the theory.

Yet this is what Venema argues. The vitellogenin genes in chickens share a weak similarity with corresponding genetic segments in humans. Evolutionists view the human segments as pseudogenes—broken versions of vitellogenin genes inherited from their egg-laying ancestors. Given this vitellogenin similarity between humans and chickens, for example, evolutionists such as Venema incredibly conclude that, therefore, humans and chickens evolved by random mutations from a common ancestor. Not only does that not follow, but it takes Venema to the unlikely solution of random mutations creating humans and chickens, and of course all the other species.

Venema also argues that the similarity of the vitellogenin genes between humans and chickens extends to, and is all the more confirmed by, their positioning within their respective genomes. But this argument from synteny is no different from what we saw above. When there is a loss of synteny evolution is not harmed, and the theory has another set of explanatory mechanisms available for just about any outcome. If the vitellogenin genes had been in a different order, evolution could have explained it just fine.

Affirming the consequent

In spite of these problems with his argument, Venema is enthusiastic about this evidence. In fact his enthusiasm leads to the fallacy of affirming the consequent, as he equates shared synteny (genes with similar positioning in the genomes of different species) with common descent:

This evidence increases our confidence that we are indeed looking at regions with shared synteny: in other words, a region in two present-day species that was once a region in the genome of their common ancestral population.

That is a fallacy. Ignoring the problems discussed above for the moment, even if evolution did make a hard prediction of shared synteny, and even if it was universally observed, that would not prove evolution. In that case, you would have a confirmed prediction. That is good, but it is not equivalent to a finding of evolution. Venema violates this scientific fundamental when he defines shared synteny as “a region in two present-day species that was once a region in the genome of their common ancestral population.” Unfortunately, affirming the consequent is not uncommon in the evolution literature.

A New Theory Explains How Consciousness Evolved

Consciousness Arose as a Solution

Michael Graziano’s piece on how consciousness evolved in today’s Atlantic has a strange beginning:

Ever since Charles Darwin published On the Origin of Species in 1859, evolution has been the grand unifying theory of biology. Yet one of our most important biological traits, consciousness, is rarely studied in the context of evolution

Perhaps it’s just me, but how can evolution be the grand unifying theory of biology if it doesn’t explain one of the most important biological traits?

Perhaps this doesn’t bother Graziano because he is about to announce that this particular shortcoming is coming to an end:

The Attention Schema Theory (AST), developed over the past five years, may be able to answer those questions. The theory suggests that consciousness arises as a solution to one of the most fundamental problems facing any nervous system: Too much information constantly flows in to be fully processed. The brain evolved increasingly sophisticated mechanisms for deeply processing a few select signals at the expense of others, and in the AST, consciousness is the ultimate result of that evolutionary sequence.

So maybe evolution wasn’t so grand, but that is now changing. A new sub hypothesis, the Attention Schema Theory (AST), might just explain how consciousness arose. Of course by “explain” evolutionists mean something along the lines of “and then a miracle occurred.”

For example, Graziano explains that a special neuron action called selective signal enhancement “probably evolved sometime between hydras and arthropods—between about 700 and 600 million years ago.” And how do evolutionists know that? Well because arthropods had it and hydras didn’t. So it must have evolved between them. After all, selective signal enhancement had to have evolved at some point. Didn’t it?

That is often what passes for an explanation in evolutionary theory.

Then there is the part of the brain called the tectum which “probably evolved around then [520 million years ago], during the so-called Cambrian Explosion.” Because, well, why not?

One reason explanations come so easily to evolutionists is that, though the theory technically is restricted to aimless mechanisms, in fact the thinking is teleological. Look at the explanation above for example. Consciousness, the professor explains, arose “as a solution” to the problem of too much information.

As a solution for a problem? That is teleological thinking.

Somewhere Aristotle is smiling.

And again, the brain evolved increasingly sophisticated mechanisms “for deeply processing” a few select signals.

For deeply processing? That, in this strange language we call English, is another version of the infinitive form. And as we have seen many times, when it comes to origins, the infinitive form is the essence of teleological language.

Religion drives science, and it matters.

Larry Klayman: Federal Judges Are Human

Kangaroo Court

Our federal legal system has become the focus of the latest political battle and Larry Klayman has now weighed in, explaining that the federal judiciary is “politicized, frequently intellectually dishonest and in some quarters even totally corrupt.” Klayman adds that federal judges “frequently take the bench after confirmation without any training in how to be a judge.” What Klayman could have added is that such problems are not confined to the backwaters of the judiciary.

Consider Judge John Jones—exalted as one of Time magazine’s 100 Most Influential People of the Year—who unbelievably revealed that he wanted to see the movie Inherit the Wind a second time in preparation for the famous 2005 Dover case, over which he presided, because, after all, the film puts the origins debate into its proper “historical context.”

That is shocking.

Jones had been so indoctrinated by the Warfare Thesis that he actually believed the evolutionary propaganda to be historically accurate. What an incredible misconception.

Jones later reminisced about the trial, explaining that “I understood the general theme. I’d seen Inherit the Wind.”

If ever there was an example of judicial bias and a predetermined verdict, this is it.

BioLogos, Broken Genes, and Urate Oxidase

The Bigger They Come, The Harder They Fall

Arguments for evolution, the theory that the biological world arose strictly by chance and natural law, are at a high level. The details of how microbes, fish, amphibians, reptiles, birds and the rest actually were created by random mutations are hard to come by. But, evolutionists explain, the species look like they evolved. Don’t the comparisons of their anatomy, geographical locations, and so forth, make evolution the obvious explanation for their origin? One of the strongest such evidences, according to evolutionists such as Dennis Venema, are the so-called shared-errors. Meaningless or, better yet, harmful mutations found in allied species seem to be obvious signs of a common ancestor. For we would never expect such harmful mutations to have arisen independently. They must derive from a common ancestor. This argument has many problems and seems to be another example of how the stronger that an argument is for evolution, the more deeply it is flawed.

One of the problems with this argument is that it contains two suspicious, unspoken, assumptions.

First, the argument assumes that these mutations are meaningless or harmful. That assumption may well be true but, as any historian of evolutionary thought knows, it is a dangerous. The history of evolutionary thought is full of claims of bad, inefficient, useless designs which, upon further research were found to be, in fact, quite useful.

Second, the argument assumes that these mutations are random. In other words, it assumes there cannot be any common mechanisms, properly operating or otherwise, which could tend toward certain designs and mutations.

In fact convergence is ubiquitous and rampant in biology. Repeated designs appear in species so distant that, according to evolutionary theory, their common ancestor could not have had that design. So even evolutionists must agree that common designs must have arisen independently. And this must have occurred many times over, at both the morphological and molecular levels.

In other instances, such “convergence” must have occurred even in allied species. In fact this is true even for the so-called harmful mutations. For instance, evolutionists believe the urate oxidase enzyme, which catalyzes the oxidation of uric acid, was inactivated in humans and the great apes by harmful random mutations. But the different versions of the gene, in the different species, do not easily align with the expected evolutionary pattern. In fact, even evolutionists have to agree that several of the various inferred mutations, in these similar species, could not have arisen from a common ancestor. Instead, they must have arisen independently:

One exceptional change is a duplicated segment of GGGATGCC in intron 4 which is shared by the gorilla and the orangutan. However, because this change is phylogenetically incompatible with any of the three possible sister-relationships among the closely related trio of the human, the chimpanzee, and the gorilla, it might result from two independent duplications. Alternatively, though less likely, a single duplication occurred in the ancestral species of the great apes and had been polymorphic for a sufficiently long time to permit fixation of the duplicated form in the orangutan and the gorilla on one hand and loss in the human and the chimpanzee on the other hand.

The nonsense mutation (TGA) at codon 107 is, however, more complicated than others. It occurs in the gorilla, the orangutan, and the gibbon, and therefore requires multiple origins of this nonsense mutation.

In contrast, the exon 3 mutation is not shared by H. syndactylus but by the gorilla and the orangutan. The origin of this mutation is therefore multiple and relatively recent in the gibbon lineage.

In other words, when common mutations found in different species cannot easily be explained by common descent, evolutionists do not hesitate to explain them as a consequent of multiple, independent events. This means that, even according evolutionists, similar mutations in allied species do not imply or require common descent. This contradicts the shared-error argument that is supposed to be one of the most powerful evidences for evolution. Unfortunately evolutionists do not include this information in their presentations of the shared-error argument.

The stronger that an argument is for evolution, the more deeply it is flawed.

ASCB Addresses Problem of False Science

The Most Important Recommendation of All

The American Society for Cell Biology (ASCB) task force on reproducibility in life science research has issued an undated white paper on scientific rigor. The problem is, as we discussed here and here, life science research has been found to lack reproducibility. John Ioannidis is a bit more blunt as he explains that “most published research findings are false,” and that “claimed research findings may often be simply accurate measures of the prevailing bias.” The ASCB white paper is no doubt a step in the right direction. It offers 13 recommendations to encourage more rigor in training, publishing, and standards. But the most important recommendation of all continues to be ignored.

Daniel Sarewitz has noted not only the problem of bias in scientific research but also the causes. Note his final thought in this quote:

All involved benefit from positive results, and from the appearance of progress. Scientists are rewarded both intellectually and professionally, science administrators are empowered and the public desire for a better world is answered. The lack of incentives to report negative results, replicate experiments or recognize inconsistencies, ambiguities and uncertainties is widely appreciated — but the necessary cultural change is incredibly difficult to achieve.

And so it is that science’s much touted self-correcting, feedback loop which ensures science converges on the truth (after all, that’s what Mr. Wells told us in seventh grade science class) is sometimes a little slow to act.

And if the ASCB is still needing to remind scientists to clean their beakers and use checklists, imagine the difficulty in achieving more fundamental change?

This brings us to the recommendation that ASCB did not make—the most important of all. And that is for science to free itself of the excessive metaphysics. Unfortunately, progress on that front is glacial. As Sarewitz notes, one reason bias persists, and is so harmful, is that in the moment it is not perceived as bias. Asking an evolutionist to stop with the metaphysics goes nowhere because it isn’t recognized as metaphysics. Deep philosophy is a part of their “science” as much as red meat is a part of hamburgers.

Even if the ASCB task force members wanted to address this fundamental problem, they wouldn’t for the backlash would be overwhelming and their professional reputations would be ruined.

So while the pipettes will be sterilized and results double checked to the third decimal point, ASCB will continue to publish junk science driven by the Epicurean mandate that the world must have arisen spontaneously. Unfortunately, the ASCB task force has missed the most important recommendation of all.

Shared Errors: BioLogos on Broken Genes

Toward a Consensus

In my previous articles (here, here and here) I reviewed Dennis Venema’s articles (here, here and here) which claimed that (i) the genomes of different species are what we would expect if they evolved, and  (ii) in particular the human genome is compelling evidence for evolution. Venema makes several confident claims that the scientific evidence strongly supports evolution. But as I pointed out Venema did not reckon with an enormous body of contradictory evidence. It was difficult to see how Venema could make those claims. Fortunately, however, we were able to appeal to the science. Now, as we move on to Venema’s next article, that will all change.

In his next article, Venema introduces a new kind of genetic evidence for evolution. Again, Venema’s focus is on, but not limited to, human evolution. Venema’s argument is that harmful mutations shared amongst different species, such as the human and chimpanzee, are powerful and compelling evidence for evolution. These harmful mutations disable a useful gene and, importantly, the mutations are identical.

Are not such harmful, shared, mutations analogous to identical typos in the term papers handed in by different students, or in historical manuscripts? Such typos are tell-tale indicators of a common source, for it is unlikely that the same typo would have occurred independently, by chance, in the same place, in different documents. Instead, the documents share a common source.

Now imagine not one, but several such typos, all identical, in the two manuscripts. Surely the evidence is now overwhelming that the documents are related and share a common source.

And just as a shared, identical, typos are a tell-tale indicator of a common source, so too must shared harmful mutations be proofs of a common ancestor. It is powerful and compelling evidence for common descent. It is, explains Venema, “one of the strongest pieces of evidence in favor of common ancestry between humans and chimpanzees (and other organisms).”

There is only one problem. As we have explained so many times, the argument is powerful because the argument is religious. This isn’t about science.

The evidence does not support the theory

The first hint of a problem should be obvious: harmful mutations are what evolution is supposed to kill off. The whole idea behind evolution is that improved designs make their way into the population via natural selection, and by the same logic natural selection (or purifying selection in this case) filters out the harmful changes. Therefore the finding of genetic sequence data which must be interpreted as harmful mutations weighs against evolutionary theory.

Also, there is the problem that any talk of how a gene proves evolutionary theory is avoiding the problem that evolution fails to explain how genes arose in the first place. Evolution claiming proof in the details of gene sequences seems to be putting the cart before the horse.

No independent changes

You could say that the heart of this “shared error” argument is the idea that “lightning doesn’t strike twice.” The identical, harmful mutations, in different species, could not have arisen independently. Instead they must have arisen only once, and then were inherited from a common ancestor.

The problem, of course, there is no reason to make this assumption. The logic made sense for written documents, but the species are not ancient manuscripts or homework assignments. They are species, and species are different.

In fact repeated designs found in otherwise distant species are ubiquitous in biology. Listening to evolutionists one would think the species fall into an evolutionary pattern with a few minor exceptions here and there. But that is overwhelmingly false. From the morphological to the molecular level, repeated designs are everywhere, and they take on many different forms.

The problem is that these repeated designs appear in species so distant that, according to evolutionary theory, their common ancestor could not have had that design. The human and squid have similar vision systems, but their purported common ancestor, a much simpler and more ancient organism, would have had no such vision system. Evolutionists are forced to say that incredibly complex designs must have arisen, yes, repeatedly and independently.

And this must have occurred over and over in biology. It would be a challenge simply to document all of the instances in which evolutionists agreed to an independent origins. For evolutionists then to insist that similar designs in allied species can only be explained by common descent amounts to having it both ways.

Bad designs

This “shared error” argument also relies on the premise that the structures in question are bad designs. In this case, the mutations are “harmful,” and so the genes are “broken.” And while that may well be true, it is a premise with a very bad track record. The history of evolutionary thought is full of claims of bad, inefficient, useless designs which, upon further research were found to be, in fact, quite useful. Simply from a history of science perspective, this is a dangerous argument to be making.


The “shared error” argument is bad science and bad history, but it remains a very strong argument. This is because its strength does not come from science or history, but rather from religion. As I have explained many times, evolution is a religious theory, and the “shared error” argument is no different. This is why the scientific and historical problems don’t matter. Venema explains:

The fact that different mammalian species, including humans, have many pseudogenes with multiple identical abnormalities (mutations) shared between them is a problem for any sort of non-evolutionary, special independent creation model.

This is a religious argument. Evolution is a referendum on creationism. It is not that the species look like they arose by random chance, it is that they do not look like they were created. Venema and the evolutionists are certain that God wouldn’t have directly created this world. There must be something between the Creator and creation—a Plastik Nature if you will. And if Venema and the evolutionists are correct in their belief then, yes, evolution must be true. Somehow, some way, the species must have arisen naturalistically.

This argument is as old as humanity. In antiquity it drove the Epicureans to conclude the world must have arisen on its own by random motion. Today evolutionists say the same thing, using random mutations as their mechanism.

Needed: an audit

Darwin’s book was loaded with religious arguments. They were the strength of his otherwise weak thesis, and they have always been the strength behind evolutionary thought. No longer can we appeal to the science, for it is religion that is doing the heavy lifting.

Yet evolutionists claim the high ground of objective, empirical reasoning. Venema admits that some other geneticists do not agree with this “shared error” argument but, he warns, they do so “for religious reasons.”

We have also seen this many times. Evolutionists make religious claims and literally in the next moment lay the blame on the other guy. This is the world according to the Warfare Thesis. We need an audit of our thinking.

The Naked Ape: BioLogos on Human Chromosome Two

Toward a Consensus

In my previous articles (here and here) I reviewed Dennis Venema’s articles (here, here and here) which claimed that the genomes of different species are what we would expect if they evolved, and in particular the human genome is compelling evidence for evolution. The claim that the empirical evidence powerfully confirms evolution is an objective claim that can be evaluated in the common language of science. There is no excuse why people holding even opposing views on origins cannot at least agree on what the science has to say. Unfortunately, origins discussions often get ahead of themselves, rushing to judgment and casting aspersions before the empirical science is objectively evaluated and agreed upon. My goal in this series of articles is to work toward such a common understanding.

In my previous article I responded to professor Venema’s claims that the human genome, as well as the genomes from the other primates, together are compelling evidence for evolution. We saw several serious problems with Venema’s claim. And as always, we forestall the rebuttal that those problems can be explained. The claim was that the evidences “strongly support the hypothesis that our species arose through an evolutionary process,” not that one can envision speculative and unlikely explanations for problematic data. And there are a great many problematic data. While fair-minded thinkers can argue about the finer details and specific implications, it seems abundantly clear that the typical evolutionary claim, as exemplified by Venema, that the data (genetic data in this case) make evolution compelling, is false.

How could we possibly make this claim in light of the empirical evidence? There seems to be a disconnect here.

The Human Chromosome Two

There is one piece of contradictory evidence I did not discuss in my previous article. I omitted it because Venema gives it special emphasis and so it merits its own article. This evidence is that while we humans have 23 pairs of chromosomes, for a total of 46, the chimpanzee, bonobo and gorilla each have 24 pairs of chromosomes, for a total of 48.

In my previous article I pointed out several differences in the primate genomes that contradict evolutionary theory. This difference in chromosome count is yet another fundamental problem for evolution. According to evolution, humans have 23 rather than 24 pairs of chromosomes because of a chromosome fusion event in our past history. Early in our evolutionary history we had 24 pairs of chromosomes, but the fusion event reduced this number to 23. In fact, evolutionists such as Venema present this evidence as yet another great confirmation of their theory. You can see other examples of this here and here.

But this claim made by evolutionists is at odds with the science. There are many problems with their claim, and they fall into two major categories.

First, the specific DNA sequence found in the human chromosome in question, defies any such fusion event. The repetitive telomere sequence is far too short and too dissimilar to indicate a fusion event. Furthermore the supposed fusion region is full of genes with the supposed fusion site lying within a highly expressed RNA gene. None of this makes sense on the fusion hypothesis. You can see this article for the details on why the evolutionary account is not feasible.

Second, even if, somehow, such a fusion event occurred (in spite of the DNA sequence data), it would not demonstrate evolution as evolutionists claim. For such a fusion event would have occurred in, and spread through, an early human population. There is no evolutionary relationship revealed. Even if evolution is true, this fusion event would give us no evidence for it. The fused chromosome did not arise from another species, it was not inherited from a human-chimp common ancestor, or any other purported common ancestor.

Disturbing pedagogy

As noted above, in spite of these contradictions presented by the empirical evidence, evolutionists claim this as a powerful confirmation. In fact, their presentation of this evidence is carefully crafted. The failures and contradictions are not included and the student is led to believe the false conclusion that the science makes evolution compelling.

Evolutionist Ken Miller made precisely this argument as an expert witness in federal court. And here is a typical lesson informing students that these chromosomes are “striking evidence of [human and ape] common ancestry.”

And professor Venema recounts his lecture strategy on this topic. It is a particularly disturbing account of how he sets students up for a faith-versus-science crisis that is straight out of the Warfare Thesis.

Venema explains that “only I really know what is coming,” as he carefully tailors the information that is presented to the unwitting students.

Venema takes his students through fruit fly genetics and then presents them with a graphic showing chimp and human chromosomes. But the slide is not labelled, and the students are unaware they are not looking at similar species, such as flies.

According to the class information presented, the students are led to conclude that the two unknown species in question share a common ancestor. Venema then reveals to them they are talking about the chimp and human species.

Having carefully set up the students with false science, Venema then casts their rebuttals in terms of the Warfare Thesis:

As one might expect, teaching this subject matter at times engenders controversy, crises of faith, anger and fear in students

The students, Venema explains, are “caught between their faith communities and the science.” The students have been set up. They have been manipulated with a false narrative, and any lack of acceptance is cast as a personal issue. It’s straight out of the Warfare Thesis.


It is crucial that we understand and teach the science without bias. As we have seen, common descent in general, and the particular case of chimp-human common descent, are astronomically unlikely. This is no mystery. These problems and contradictions are from the empirical evidence. Common descent makes no sense on the science. And the arguments and evidences given by evolutionists in support of common descent do nothing to change this. In fact, generally they do not even address the problems and contradictions. I hope that changes.

The Naked Ape: An Open Letter to BioLogos on the Genetic Evidence, Part II

Toward a Consensus

In my previous article I reviewed Dennis Venema’s articles (here and here) which claimed that the genomes of different species are what we would expect if they evolved. For instance, allied species have similar genomes, and genetic features fall into evolution’s common descent pattern. I argued that this claim is inaccurate and that the scientific evidence tells a very different message. In a later article Venema focused his claim on the specific case of human evolution, and the similarity between the human and chimpanzee genomes. As before, Venema finds this genetic evidence to be a compelling confirmation of evolution:

The first line of evidence in favor of humans sharing ancestry with other forms of life is straightforward – there are other species that have a genome that is nearly identical to our own – the genomes found in great apes such as chimpanzees, gorillas and orangutans. Compared to our “book,” the “books” of these species match at the chapter and paragraph level – all three species have DNA sequences that have the same genes in the same basic order as we do. There are subtle differences, of course – blocks of sequence that have been rearranged through breakage and rejoining of chromosomes, as expected – but the overall pattern is clear. […]

Taken together, what we observe when comparing the overall structure of the human genome to other primates is that (a) our genomes do indeed have the features one would predict them to have if they are copies of a shared ancestral genome, and (b) the differences we do observe are easily accounted for by well-known mechanisms. These observations strongly support the hypothesis that our species arose through an evolutionary process.

It does not seem that the evidence supports evolutionary theory as Venema concludes. In fact, there seem to be several significant problems with this claim, as I will explain.

First, as we saw in my previous article, the genetic data from the different species do not fall into the expected evolutionary pattern. Here Venema focuses on the high genetic similarity between the primates, claiming it confirms evolution. But if this is what is required to confirm evolutionary relationships, then the substantial genetic differences that are so often found between otherwise similar species must falsify evolutionary relationships in those cases.

But evolutionists have never entertained any such doubts. Those evolutionary relationships are intact, according to evolutionists, and this suggests that the high similarity between the primate genomes never was required for evolutionists to believe they evolved from a common ancestor.

So it appears that Venema’s claim, that the high genetic similarity between the primates confirms their evolutionary relationship, is more of an “after the fact” claim rather than a confirmation of a genuine evolutionary prediction. In fact, given the substantial morphological differences between humans and the other primates, evolutionists had indeed expected greater genetic differences:

The chimpanzee is our closest living relative. The morphological differences between the two species are so large that there is no problem in distinguishing between them. However, the nucleotide difference between the two species is surprisingly small.

So it does not appear that the high similarity between the chimp and human genomes was predicted by evolution, or is required by evolution. Beyond that, given the high similarity between the chimp and human genomes, there are many inconsistencies with evolution, as we shall see next.

The gorilla genome is strangely similar to both the chimp and human genomes

When the human and chimpanzee genomes were compared a few years ago, the human genes showed some surprising differences in a few places, such as in genes thought to be related to hearing. Evolutionists called it “accelerated” evolution and they said that it was due to the development of human language. However it turns out that the gorilla genome has a similar pattern. And that doesn’t make sense since gorillas don’t have our advanced verbal skills:

Much of the 15% is in sections of the genome that do not code for proteins. But the researchers also looked at functional gene changes. They found that certain genes—including some involved in hearing and brain development—had gone through more rapid changes than expected in both the gorilla and human lineage. Some of these rapid changes are puzzling: the gene LOXHD1 is involved in hearing in humans and was therefore thought to be involved in speech, but the gene shows just as much accelerated evolution in the gorilla. “But we know gorillas don’t talk to each other—if they do they’re managing to keep it secret,” says [lead author] Scally.

So now evolutionists are calling it “parallel accelerated” evolution, because the same accelerated evolution, by random mutation, must have happened independently, in the human and gorilla genomes. But why would the same “accelerated evolution” occur in the gorilla? It wasn’t developing human language. Perhaps there is some other reason, but why then wouldn’t that “accelerated evolution” occur in the chimpanzee? It doesn’t make sense with evolution, for we must say that random mutations just happened to create the same pattern twice.

The gorilla genome also shows similarities to the chimp genome, including duplications that are not present in the other primates. Evolutionists say these various chimp-gorilla similarities were coincidences, occurring repeatedly by chance in the two different species:

We show that both the gorilla and chimpanzee genomes have experienced independent yet convergent patterns of structural mutation that have not occurred in humans, including the formation of subtelomeric heterochromatic caps, the hyperexpansion of segmental duplications, and bursts of retroviral integrations.

These events must have occurred independently and in parallel.


Human uniqueness is expansive. Relative brain size, hairless sweaty skin, striding bipedal posture, long-distance running, ability to learn to swim, innate ability to learn languages in childhood, prolonged helplessness of the young, ability to imitate and learn, inter-generational transfer of complex cultures, awareness of self and of the past and future, theory of mind, increased longevity, provisioning by post-menopausal females, difficult childbirth, and cerebral cortical asymmetry are just a few from a long list of features that make humans exceptional.

Another such unique feature is at the genome level: the lack of endemic infectious retroviruses in humans. The problem is that these viruses are present in the other primates, and so according to evolution these viruses must be present in their common ancestor which, again according to evolution, would be an ancestor of humans as well. Therefore this lack of endemic infectious retroviruses in humans is inconsistent with evolution:

Other than the recent introductions of HIV and human T leukaemia virus (HTLV) into humans from other animals, humans seem to be devoid of species-wide endemic infectious retroviruses. By contrast, like most other mammals studied, other hominids and non-human primates (NHPs) do have such viruses. Indeed, given the remarkable corroboration between the phylogenetic trees of primates and their lineage-specific simian foamy viruses (SFVs) our common ancestors with other hominids almost certainly had SFVs. The same is probably true of the lineage-specific simian infectious retroviruses (SIVs) found in most NHPs. Assuming that the common ancestors of hominids carried multiple endemic infectious retroviruses, how did the human lineage eliminate them? Given that humans remain susceptible to re-infection with both SFVs and SIVs from other hominids, this seems unlikely to be explained solely on the basis of more efficient host restriction systems. Rather, there seems to have been an episode in which the ancestral human lineage was somehow ‘purged’ of these endemic viruses.

In other words, the endemic infectious retroviruses do not align with the expected evolutionary pattern. The human lineage must, somehow, have been purged of these endemic viruses. Perhaps such a purging occurred, and future research may be able to strengthen that hypothesis. But as it stands, this evidence is not consistent with evolution.

Chimp-human genome beneficial differences are few

As noted above, evolutionists were surprised by the high similarity between the chimp and human genomes. With so few differences, how could evolution construct such tremendous differences? But not only is evolution limited to a relatively few genetic modifications to create the human, but according to evolution the majority of even those modifications would likely have had little or no consequence or even would have been slightly harmful. Here is how a 2005 paper on the chimpanzee-human genome comparisons put it:

In particular, we find that the patterns of evolution in human and chimpanzee protein-coding genes are highly correlated and dominated by the fixation of neutral and slightly deleterious alleles.

The paper is written from an evolutionary perspective, assuming that humans and chimpanzees share a common ancestor. Given that a priori assumption, they were forced to conclude that most of the mutations affecting protein-coding genes led to “neutral and slightly deleterious alleles.” So not only are evolution’s random mutation resources meager, in terms of both quality and quantity as explained above, but even worse, those mutations mostly led to “neutral and slightly deleterious alleles.”

In fact the beneficial mutations in protein-coding genes, which presumably would be important in evolving the human from a small, primitive ape, literally number only in the hundreds. It would be astonishing if the human could be evolved from so few mutations.

Chimp-human genome differences have discrepancies

Furthermore, the chimp-human genome differences show some strange patterns, with unexplainable variation towards the ends of most chromosomes, and with the chromosomal banding patterns.

A common response from evolutionists is that these discrepancies are small in magnitude. That is true, they are small in magnitude. But that is not what counts. Molecular spectra that make magnetic resonance imaging (MRI) possible are also small in magnitude. That doesn’t mean they don’t count. What is important is that the chimp-human genome differences show patterns that evolutionary theory struggles to account for. The evidence is not consistent with the theory, by a wide margin.

The chimp-human genome differences has also been described using sliding 1-Mb windows. Those results also showed nonrandom variations, but later research found that those variations correlate with the observed de novo human mutation rate patterns. The research paper concluded that the variation in chimp-human genome differences “is only partly explained” by the mutation rate patterns. But these results raise the specter that the variations in the chimp-human genome differences seen in 1-Mb windows may be explainable by a known phenomenon.

This suggests the possibility that future research may also explain the variation towards the ends of chromosomes, and with the chromosomal banding patterns. But that was not the claim. Evolutionists such as Venema claim that today’s evidences “strongly support the hypothesis that our species arose through an evolutionary process.”

Chimp-human alternate splicing differences

You may have learned in your high school biology class that genes are segments of DNA, but it is a bit more complicated than that. For starters, in the higher species a gene is often not a simple continuous segment of DNA but rather is interrupted several times by intervening segments. So there are the coding segments (called exons for expressed regions) and then there are the intervening segments (called introns for intervening regions).

When a gene is transcribed, the transcript contains both the exons and introns. It is then spliced by a complicated spliceosome machine that removes the introns from the gene copy and glues the exons together.

One of the features of the exon/intron genetic architecture is that it allows for alternative splicing schemes. In fact, incredibly, a given gene can have thousands of different forms depending on how the spliceosome machine edits the gene.

When it was discovered that the human genome contained about twenty five thousand genes it seemed too few. Are not more genes required for a human body? More recently it has been discovered that we make up for that small number of genes with alternative splicing schemes. Most of our genes may undergo such editing, and the result can be a completely different function for the resulting protein.

We have an enormous alternative splicing program in our cells, far more than chimps have. And this is another inconsistency with evolutionary theory.

Given the high similarity between the chimp and human genomes, and the relatively few beneficial mutations in protein-coding genes (discussed above), evolutionists have considered the possibility of evolution by splicing. In other words, our enormous alternative splicing program may have been an important factor in our evolving from a small, primitive ape.

But there are many thousands of these gene splicing changes that would have to evolve. And unlike bacteria whose populations are large and generation times are short, our gene splicing changes would have to evolve in smaller populations with longer generation times.

It is difficult to see how evolution would have the resources to make this happen. The problem quickly becomes astronomically improbable if groups of genes would need to implement their new splicing logic together. And how could that not be the case?

In fact, even if only the order of implementing splicing for a small number of genes is important, the problem quickly becomes astronomically improbable. And again, how could that not be the case?

But this is only the beginning. In addition to the fact that the evolution of our enormous gene splicing changes is unlikely, it also represents an enormous serendipity problem. We would have to say that random mutations constructed complicated genes, with exons and introns and splicing codes, and the incredible splicing machinery, which, it would just so happen, would luckily be just what was needed to evolve humans.

It is even worse than this when one considers the exons themselves. Those random mutations would have divided the genetic instructions into so many exons, and it just so happened that they would be the right building blocks that, when rearranged, would lead to humans. The serendipity is astronomical here.

Imagine if you were building a tricycle and your friend modified each part you had crafted (not adding anything), and now the parts fit together to construct the space shuttle rocket motor.

The kangaroo-human genomes

In my previous article I explained that, in addition to striking differences in otherwise allied species, striking similarities in otherwise distant species are also inconsistent with evolution. This problem arises also with the human genome. Consider the kangaroo genome, which turned out to be similar to the human genome. As one evolutionist explained:

There are a few differences, we have a few more of this, a few less of that, but they are the same genes and a lot of them are in the same order. Which really surprised us, we thought they’d be completely scrambled, but they’re not, there’s great chunks of the human genome which is sitting right there in the kangaroo genome.

It was a surprise because under evolution humans and kangaroos must be quite distant relatives. Evolutionists believe a small mouse-like species split into two lineages—the marsupials and the placentals—about 150 million years ago. And according to evolutionists that mouse-like species eventually evolved by random mutations into, among other things, a kangaroo in the one lineage and into a human in the other. With that much evolutionary distance the kangaroo and human genomes should have evolved substantial differences.


The genomes of primates do not support evolutionary theory. As we have discussed, there are always speculations for whatever evidence is discovered. Perhaps evolution did this, perhaps it did that. But that does not change the fact that the primate genomes do not “strongly support the hypothesis that our species arose through an evolutionary process,” as Venema and the evolutionists claim. There are a wide variety of substantial contradictions and problems with this theory.

The Naked Ape: An Open Letter to BioLogos on the Genetic Evidence

Toward a Consensus

Dennis Venema, professor of biology at Trinity Western University, has written a series of articles that have been noted by evolutionists for their clarity and persuasiveness. So as a collector of evidences and reasons why evolution is a fact, I was interested to see Venema’s articles. What does the professor have to say to help confirm what Samuel Wilberforce rhetorically called “a somewhat startling conclusion”?

One of Venema’s basic points (see here and here) is that the genomes of different species are what we would expect if they evolved. Allied species have similar genomes, and genetic features fall into evolution’s common descent pattern:

If indeed speciation events produced Species A – D from a common ancestral population, we would expect their genomes to exhibit certain features when compared to each other. First and foremost, their overall genome sequence and structure should be highly similar to each other – they should be versions of the same book, with chapters and paragraphs of shared text in the same order. Secondly, the differences between them would be expected to fall into a pattern.

Does the evidence confirm these evolutionary expectations? Venema answers with an emphatic “yes.”

Here Venema is appealing to the empirical evidence. He is comparing the evidence to the theory of evolution, and finding that the evidence confirms evolution’s predictions. This means the theory can be empirically evaluated. And if evolution can be genuinely evaluated empirically, then it is, at least theoretically, possible for evolution to fail. If the evidence can confirm evolution, then it also can disconfirm evolution.

This is important because focusing the attention on the evidence means the non scientific arguments go away and science is allowed to speak. What does it say? Here I will take the opposing view, for it seems that what the science shows is that Venema’s claim, that the genetic evidence confirms evolutionary predictions, is inaccurate.

This is not to say that evolutionary explanations cannot be offered. As philosophers well understand, another sub hypothesis is always possible. Such hypotheses raise more profound questions of parsimony, likelihood and so forth. But it seems that such philosophical questions ought to be addressed after there is a consensus on what the empirical evidence has to say. The goal here is to move toward that consensus. Venema, and evolutionists in general, make a straightforward claim about the evidence. We ought to be able to dispassionately evaluate that claim.

Of course I realize that reaching consensus is not as simple as reading an article. There will be differing interpretations by fair-minded critics. And the topic of origins is certainly not always dispassionate. If you argue against evolution you will be disparaged. My response to such attacks has and always will be to forgive.

One final preliminary is simply to point out that it is a challenge just to do justice to this story. A thorough treatment could easily require an entire volume. But a few, typical, examples will have to suffice. They can provide readers with an approximate understanding how the evidence bears on Venema’s claim.

What does the evidence say?

For starters, phylogenetic incongruence is rampant in evolutionary studies. Genetic sequence data do not fall into the expected evolutionary pattern. Conflicts exist at all levels of the evolutionary tree and throughout both morphological and molecular traits. This paper reports on incongruent gene trees in bats. That is one example of many.

MicroRNAs are short RNA molecules that regulate gene expression, for example, by binding to messenger RNA molecules which otherwise would code for a protein at a ribosome. Increasingly MicroRNAs are understood to be lineage-specific, appearing in a few species, or even in just a single species, and are nowhere else to be found. In fact one evolutionist, who has studied thousands of microRNA genes, explained that he has not found “a single example that would support the traditional [evolutionary] tree.” It is, another evolutionist admitted, “a very serious incongruence.”

Trichodesmium or “sea sawdust,” a genus of oceanic bacteria described by Captain Cook in the eighteenth century and so prolific it can be seen from space, has a unique, lineage-specific genome. Less than two-thirds of the genome of this crucial ammonium-producing bacteria codes for proteins. No other such bacteria has such a low value, and conversely such a large percentage of the genome that is non coding. This lineage-specific genome, as one report explains, “defies common evolutionary dogma.”

It is not unusual for similar species to have significant differences in their genome. These results have surprised evolutionists and there does not seem to be any let up as new genomes are deciphered.

The mouse and rat genomes are far more different than expected. Before the rat genome was determined, evolutionists predicted it would be highly similar to the mouse genome. As one paper explained:

Before the launch of the Rat Genome Sequencing Project (RGSP), there was much debate about the overall value of the rat genome sequence and its contribution to the utility of the rat as a model organism. The debate was fuelled by the naive belief that the rat and mouse were so similar morphologically and evolutionarily that the rat sequence would be redundant.

The prediction that the mouse and rat genomes would be highly similar made sense according to evolution. But it was dramatically wrong.

One phylogenetic study attempted to compute the evolutionary tree relating a couple dozen yeast species using 1,070 genes. The tree that uses all 1,070 genes is called the concatenation tree. They then repeated the computation 1,070 times, for each gene taken individually. Not only did none of the 1,070 trees match the concatenation tree, they also failed to show even a single match between themselves. In other words, out of the 1,071 trees, there were zero matches. It was “a bit shocking” for evolutionists, as one explained: “We are trying to figure out the phylogenetic relationships of 1.8 million species and can’t even sort out 20 yeast.”

What is interesting is how this false prediction was accommodated. The evolutionists tried to fix the problem with all kinds of strategies. They removed parts of genes from the analysis, they removed a few genes that might have been outliers, they removed a few of the yeast species, they restricted the analysis to certain genes that agreed on parts of the evolutionary tree, they restricted the analysis to only those genes thought to be slowly evolving, and they tried restricting the gene comparisons to only certain parts of the gene.

These various strategies each have their own rationale. That rationale may be dubious, but at least there is some underlying reasoning. Yet none of these strategies worked. In fact they sometimes exacerbated the incongruence problem. What the evolutionists finally had to do, simply put, was to select the subset of the genes that gave the right evolutionary answer. They described those genes as having “strong phylogenetic signal.”

And how do we know that these genes have strong phylogenetic signal. Because they gave the right answer. This raises the general problem of prefiltering of data. Prefiltering is often thought of merely as cleaning up the data. But prefiltering is more than that, for built-in to the prefiltering steps is the theory of evolution. Prefiltering massages the data to favor the theory. The data are, as philosophers explain, theory-laden.

But even prefiltering cannot always help the theory. For even cleansed data routinely lead to evolutionary trees that are incongruent (the opposite of consilience). As one study explained, the problem is so confusing that results “can lead to high confidence in incorrect hypotheses.” As one paper explained, data are routinely filtered in order to satisfy stringent criteria so as to eliminate the possibility of incongruence. And although evolutionists thought that more data would solve their problems, the opposite has occurred. With the ever increasing volumes of data (particularly molecular data), incongruence between trees “has become pervasive.”

What is needed now is less data. Specifically, less contradictory data. As one evolutionist explained, “if you take just the strongly supported genes, then you recover the correct tree.” And what are “strongly supported” genes? Those would be genes that cooperate with the theory. So now in addition to prefiltering we have postfiltering.

Another issue are the striking similarities in otherwise distant species. This so-called convergence is rampant in biology and it takes on several forms.

Consider a paper from the Royal Society on “The mystery of extreme non-coding conservation” that has been found across many genomes. As the paper explains, there is currently “no known mechanism or function that would account for this level of conservation at the observed evolutionary distances.” Here is how the paper summarizes these findings of extreme sequence conservation:

… despite 10 years of research, there has been virtually no progress towards answering the question of the origin of these patterns of extreme conservation. A number of hypotheses have been proposed, but most rely on modes of DNA : protein interactions that have never been observed and seem dubious at best. As a consequence, not only do we still lack a plausible mechanism for the conservation of CNEs—we lack even plausible speculations.

And these repeated designs, in otherwise different species, are rampant in biology. It is not merely a rare occurrence which perhaps evolution could explain as an outlier. That the species do not fall into an evolutionary tree pattern is well established by science.

Furthermore, these repeated designs do not merely occur twice, in two distant species. They often occur repeatedly in a variety of otherwise distant species. So now the evolutionist must not only believe that there are many of these repeating design events, but that in most cases, they repeat multiple times, in disparate species.

Evolutionists have labeled this evidence as recurrent evolution. As a recent paper explains:

The recent explosion of genome sequences from all major phylogenetic groups has unveiled an unexpected wealth of cases of recurrent evolution of strikingly similar genomic features in different lineages.

In addition, many instances of a third more puzzling phylogenetic pattern have been observed: traits whose distribution is “scattered” across the evolutionary tree, indicating repeated independent evolution of similar genomic features in different lineages.

Of course these puzzling, striking similarities cannot be explained by common evolutionary history. Instead, they are explained by common evolutionary forces:

As ancestrally shared features are the result of a common evolutionary history, shared features evolved by recurrent evolution are often the result of common evolutionary forces acting on different lineages.

If the pattern fits the evolutionary tree, then it is explained as common evolutionary history. If not, then it is explained as common evolutionary forces.

With all of this contradictory evidence, even evolutionists have realized in recent years that the traditional evolutionary tree model is failing. As one evolutionist explained, “The tree of life is being politely buried.”

There are many more fascinating examples of biological patterns that are not consistent with the expected evolutionary pattern. These are not anomalies or rare exceptions. Here we have focused on the genetic level since that was the theme of Venema’s article. It seems that the species and their genomes do not fall into a consistent evolutionary pattern as evolutionists such as Venema claim. This does not mean evolutionists cannot explain any of this. They have a wide spectrum of mechanisms to draw upon, of varying levels of speculation and likelihood. These explanatory mechanisms greatly increase the theory’s complexity. They raise questions of realism, and whether the theory is following the data, or the data is following the theory. But such questions are for another day.

The point here is that evolutionist’s claims that the genomic data broadly and consistently fall into the evolutionary pattern and expectations do not seem to reflect the empirical data. This is the first step in moving the discourse forward. We need to reach consensus on what the evidence reveals.

Next time I will continue with an examination of the next evidences Venema presents.

New Study Reveals How the Shape of My Nose Arose

The Nose Knows

It is ironic that Charles Lyell, whose seminal, if flawed, work in geology—the barrister is sometimes known as the father of modern geology—positively influenced Charles Darwin’s development of evolutionary theory—the young Darwin read Lyell’s book as he sailed around the world in the H.M.S. Beagle—and who helped to arrange for Darwin’s first formal, if awkward, presentation of his theory—an event precipitated by Wallace’s Ternate letter—was one of the last of the intelligentsia to accept Darwin’s new formulation of Epicureanism, known as evolution.

At one point an exasperated Darwin asked Lyell—it always comes down to metaphysics—if he believed “the shape of my nose was designed?” If Lyell did think so then, Darwin added, “I have nothing more to say.” The infra-dignitatem, or infra-dig for the irreverent, argument, which insisted that it was beneath the dignity of the Creator to stoop so low as to dwell in the details of the world, had been promoted by no less than the father of natural theology John Ray and Platonist Ralph Cudworth, and in Darwin’s day was in full swing. Its influence on the young Darwin was clear in the naturalist’s early notebooks, and here in his appeal to Lyell. One look at one’s nose is all one needs to know about origins. Obviously we evolved. Now, a century and a half later, science finally has its say in the matter.

A new study out of, appropriately enough, England, now reveals the underlying genetic details that influence the shape of our noses. It seems there are four genes that influence the width and length of our olfactory device and, as the press release informs us, “The new information adds to our understanding of how the human face evolved.”

Glad to have that cleared up. Religion drives science, and it matters.

Local Fitness Landscape Mapped Out For Green Fluorescent Protein

It’s Just Getting Worse

As we have discussed many times, proteins are a show-stopper for evolution. Proteins consist of dozens, hundreds and even thousands of amino acids and, like most machines, they don’t work very well until most of the parts (amino acids in this case) are in place. Half of the amino acids don’t give you half the function of a protein. You can read more about this here and here. Now, a new paper reinforces the problem of protein evolution.

One approach to studying how evolution could create new protein designs is to start with some sort of random sequence of amino acids, see how well it works, and try to evolve it to obtain a protein. This is difficult because the protein design space is astronomically huge and proteins are sparse within that space. Any random sequence of amino acids will merely give you junk. Furthermore, the fitness landscape is flat and doesn’t provide the guidance evolution needs to move toward functional proteins.

Another approach is to start at the end and work backwards. In other words, start with the finished product—a functional protein—and see what the fitness landscape looks like as you swap in different amino acids. This is difficult because, unfortunately for evolution, the fitness landscape drops off precipitously as you move away from the native protein design. Modifying only a few percent of the amino acids leads to a rapid loss of function.

The new paper takes this second approach. It uses a bioluminescent protein known as the green fluorescent protein, taken from the jellyfish, Aequorea victoria. It is a wonderful study that systematically mapped out the protein’s function (as measured by the protein’s fluorescence) for a total of 51,715 different protein sequences that are nearby the native sequence.

The results confirmed what earlier studies had indicated: the protein function drops off dramatically with only a relatively small number of substitutions. But the study also explored the effect of multiple substitutions. It is well known that the effect of two substitutions, for example, are not always simply the sum of their individual effects. They can interact with each other in either positive or negative ways. This is referred to as epistasis.

The new study found that negative epistasis was strong and prevalent. As one of the researchers explained:

We were really surprised when we finally had a chance to look at exactly how the interactions between mutations occur. We also did not expect that almost all the mutations that are only slightly damaging on their own can destroy fluorescence completely when combined together.

It was well understood that evolving a protein is an astronomically unlikely event, and these results indicate it is even more difficult. Those negative results, however, were not reported in the paper. Instead, the paper discussed possible ways that one green fluorescent protein, found in one particular species, may have evolved into other green fluorescent proteins, found in other species. The implications for the initial evolution of a protein were ignored.

We Can Say It, But You Can’t

Highly, Intricately, and Precisely Integrated Networks of Entities and Interactions

As Carl Woese explained in 2004:

The cells we know are not just loosely coupled arrangements of quasi-independent modules. They are highly, intricately, and precisely integrated networks of entities and interactions. … To think that a new cell design can be created more or less haphazardly from chunks of other modern cell designs is just another fallacy born of a mechanistic, reductionist view of the organism.

Mechanistic, reductionist view? It appears Woese put his finger on precisely what he believed in: evolution. Replace “cell” with just about any biological structure and Woese has, in a nutshell, summarized evolutionary theory, what little there is of it. As Richard Dawkins once explained:

The bombardier beetle’s ancestors simply pressed into different service chemicals that already happened to be lying around. That’s often how evolution works.

Religion drives science, and it matters.

A Response to VJ Torley

One Long Argument

To read VJ Torley’s analysis of my criticism of S. Joshua Swamidass’ recent article, Evidence and Evolution, one would think that I mercilessly berated a poor fellow who was merely attempting to “extend an olive branch to creationists.” After all, nowhere did Swamidass belittle or ridicule his opponents, and nowhere was there so much as a trace of the smug superiority. And the guy is a Christian, not some atheistic reductionist. In fact, Swamidass does not even draw any conclusions in his article.

This is how Torley begins his article and unfortunately this gives those who have not read the two articles the wrong impression. I gave a lengthy, fact-based, scientific criticism of Swamidass’ claims which was not dismissive or sarcastic. I did not accuse of Swamidass of belittling or ridiculing anyone, nor did I accuse him of smugness, academic or otherwise. And I did not question his religious beliefs. All of this was injected by Torley.

As for drawing conclusions, yes contrary to Torley, Swamidass draws conclusions. He states in no uncertain terms that the evolutionary story “is by far the best scientific explanation of our origins.” In fact, the evidence is stunning:

What is the evidence for human common ancestry with apes? The strongest evidence is a series of stunningly accurate predictions about human genomes that have been confirmed in recent decades as the human and ape genomes have been sequenced.

The idea that Swamidass does not draw conclusions is inaccurate. Swamidass goes on to suggest that microevolution is sufficient to explain the evolution of humans from a small, ape-like creature.

Throughout his piece, Swamidass uses a scientist versus theologian, Warfare Thesis perspective. Scientists simply refer to the data whereas theologians must adjust their sights, drop their denial, and grapple with the undeniable truths of evolution. To object is futile and attempts to explain humans as a product of design are “lawyerly”:

A common lawyerly objection to this evidence is that these similarities are “equally” explained by common “design.” As scientists, our response to this objection is data.

Perhaps the theologian “could look for errors in the scientific analyses,” but even that would be futile:

Still, even if he [the theologian] found standing for quibbles here and there, the overall picture would remain the same and the evidence against common ancestry, at best, would be subtle and debatable.

Swamidass presents a story in order to “reduce the fear some feel when encountering evidence that might contradict their understanding of the Bible.”

This is all Warfare Thesis, and Torley finds it to be “irenic in tone, easy to follow, deeply learned, and absolutely right.”

On the other hand Torley throws occasional ad hominems my way and finds that my critique of Swamidass’ piece was “polemical and curtly dismissive in tone.” In fact, my criticism was about Swamidass’ arguments. I pointed out that his scientific claims were erroneous and that ultimately his arguments relied on metaphysical claims.

This is not to say there cannot be improvements in my article. It is, after all, a blog post. I’m thankful for feedback and corrections to my errors. But Torley’s casting of the two articles is simply a misrepresentation. It seems that his criticism of my post is, in fact, more applicable to his article.

What about the science?

Torley next castigates me for ignoring the main scientific evidence Swamidass presents. And what is Torley referring to? A series of references Swamidass made. So instead of addressing the key scientific claims made by Swamidass (which I did), I am supposed to do an expansive analysis on several references Swamidass provided as backup.

In fact I was planning on getting to those references at some point, time permitting, as they are yet more examples of failed science. But Torley’s requirements and criticisms are unrealistic.

Torley next quotes from one of Swamidass’ references, imagines what my response would be, and argues with it. This is getting silly. Normally I would not respond to this type of article, but this is different since it appears so close to my article.

Torley finishes with a series of erroneous rebuttals, ad hominems, and strawmen arguments. To be sure, Torley makes some good tangential points, but they are unfortunately the minority in a series of failed arguments.

Not surprisingly Torley shares Swamidass’ theological convictions which underwrite their claims. Their contrastive reasoning, if correct, proves their case. As Torley writes:

On a special creationist account of human origins, there is absolutely no reason to expect that humans would have what appear to be the remains of genes used for making egg yolks in their DNA – just as there is no particular reason to expect that humans would be more genetically similar to chimps than rats are to mice – or for that matter, than foxes are to wolves, or horses are to donkeys. [emphasis in original]

No reason. If Torley is correct here then, yes, we can safely conclude for evolution. Likewise:

Reasoning on Bayesian grounds, these striking and singular facts have a high probability on the hypothesis of common descent, but are surprising (and hence improbable) on a hypothesis of separate creation. One can only conclude that these facts lend scientific support to the hypothesis of common descent.

True enough. Such reasoning is perfectly valid, but it hinges on metaphysical premises. From a scientific perspective, evolution and common descent are unlikely to say the least, but from a metaphysical perspective, they are compelling.

Religion drives science, and it matters.
