Thank Darwinism for free will?

 Did Evolution Give Us Free Will?


If you pick up a book up about free will by a materialist neuroscientist, you are generally safe to assume that the point of it will be to explain that free will is merely an illusion — that we are actually at the whim of the blind forces of Nature, and are therefore not responsible for our actions. So it’s surprising and somewhat refreshing to see a self-proclaimed naturalist defend free will. That’s what Trinity College Dublin neurobiologist Kevin Mitchell sets out to do in Free Agents: How Evolution Gave Us Free Will. 

As Denyse O’Leary has noted about the book, the scientific debate over free will seems to be reviving a bit, with another book by another prominent scientist arguing the opposite position released the same year (Determined by Robert Sapolsky). So after reading Mitchell’s book, I thought it would be worth digging into the details of his argument a bit for Evolutions News readers.

Does the book succeed? By my assessment, no and yes and no. There are really several different questions at play here: Do we have a will? Is it free? Did evolution give it to us? And if so, how? Each of these subjects has its own set of scientific and philosophical difficulties, and the book is not equally persuasive on every point. To keep the various strands of the argument straight, let’s go in order, following the subtitle. We’ll start with “how evolution gave us”…  

“How Evolution Gave Us…”

Anyone expecting a defense of the claim that Darwinian processes can or did create complex neurological systems will be disappointed. That’s not the point of the book. With a very few exceptions1, Dr. Mitchell works from the tacit assumption that (a) there is no real limit to what Darwinian processes can achieve, and (b) that anything that exists in biology must have arisen through Darwinian processes. That means the book is largely concerned with describing what exists in nature, with “evolved” acting as a synonym for “is.” 

Thus, phrases like “mechanisms evolved” prevail throughout the book. Complex systems are simply “built” or “invented” or even “designed,” without much concern given to the concrete details or the relevant engineering problems. The following passage is typical:

More complex creatures emerged, colonizing and creating new niches, with expanded repertoires of possible actions. A system was then required to coordinate the movement of all the organism’s constituent parts and select among actions. Muscles evolved, along with neurons to coordinate them, initially distributed in simple nerve nets. As evolution proceeded, the nervous system became more complex, linking sensory structures to muscles via intervening layers of interneurons. The meaning of signals became disconnected from immediate action, giving rise to internal representations…   

In all fairness, Mitchell presumably did not set out to defend Darwinian evolution against other possible explanations. The heart of Free Agents is not really in explaining how we evolved to be what we are, but rather in simply describingwhat we are, according to the cutting edge of neurobiology. That’s where the book shines.

“Free”
One view of free will, called “compatibilism,” maintains that materialistic determinism and free will are really compatible. This position is apparently quite popular in philosophy of mind circles, and has been argued by Daniel Dennett and other famous philosophers. The argument says, first, that it doesn’t matter if an organism “could have done otherwise” — what matters is that the organism is the source of the action. That is, we can reasonably be said to have free will if we are able to do what we want, even if we are not able to want what we want. Second, compatibilists point out that organisms and their environments are so complex that there is no way, even theoretically, to predict what an organism will do in a future situation. So for all practical purposes, we are free. 

Mitchell finds these arguments unconvincing. They seem to be saying that if we just change our perspective, or our definitions, the problem will go away. “But I cannot escape feeling that some sleight of hand is part of this line of argument,” he writes. “It feels as if some (presumably unwitting) misdirection is going on — as if the primary problem has been circumvented or even denied, rather than confronted.” Instead, there ought to be some genuine indeterminacy in the system, or else “no matter how complex, the agent will be pushed around deterministically by its own components.” 

I think the “sleight of hand” Mitchell senses is the confusing of epistemology with ontology: confusing what can be known with what is. Regardless — Mitchell argues that the fuss is unnecessary. There is really no reason that free will needs to be compatible with strict determinism, he says, because physics, as it turns out, is not strictly deterministic. That requirement is a relic from a bygone era, when everything seemed to move inexorably according to simple Newtonian laws. Most modern quantum physicists, in contrast, agree that particles seem to actually have a degree of freedom or true randomness to their movement. So, Mitchell says, “there is nothing in the laws physics that rules out the possibility of agency or free will, a priori.” 

In fact, various studies seem to show organisms acting in a non-deterministic way. In one fascinating experiment, an electrical probe was attached directly to a leech’s central nervous system, allowing the experimenters to bypass the complexities of environment altogether and administer the exact same stimulus, repeatedly. Even under such perfectly controlled conditions, there seemed to be no way to predict how a leech (like the one pictured above) would respond to the stimulus each time. 

This apparent indeterminacy scales all the way up to more complex behaviors and situations, resulting in what is known as the Harvard Law of Animal Behavior: “Under carefully controlled experimental circumstances, an animal will behave as it damn well pleases.” 

So Far, So Good

But what about the experiments that seem to show the opposite, that free will is a mere illusion?

There are quite a few famous experiments of this kind, but in Mitchell’s professional opinion, they show nothing of the sort.

For example, Benjamin Libet’s now-famous 1983 experiment showed a signal called a “readiness potential” in the brain a fraction of a second before the subject was conscious of choosing to move his hand. Many have taken this to be definitive proof that free will is only an illusion: at the moment we think we are freely choosing, the brain has actually decided beforehand. 

Mitchell writes that this interpretation is “to put it mildly, a drastic overinterpretation”: 

That is because the design of the experiment makes it effectively irrelevant for the question of free will. The participants made an active and deliberate decision when they agreed to take part in the study and to follow the instructions of the researchers. Those instructions explicitly told them to act on a whim: “to let the urge to act appear on its own at any time without any preplanning or concentration on when to act.” They had no reason to want to move their hand more at one point than another because nothing was at stake. And so, it seems they did indeed act on a whim: they (decided to) let subconscious processes in their brains decide, by drawing on inherent random fluctuations in neural activity. 

This is what a different group of neuroscientists, led by Aaron Schurger, concluded from analyzing the data from the original experiment — that the test subjects had (instinctively, of course) set a certain potential level of neuronal activity, deciding that when random fluctuations in the brain reach that level, they would take the proscribed action. 

So now you have two plausible interpretations of the data. 

But Which One Is True? 

Another experiment, led by Uri Maoz and Liad Mudrik, sought to distinguish between the two possibilities. The researchers gave half the test subjects a decision with no serious consequences, and half a decision with consequences that they cared about. Sure enough, when the subjects were given inconsequential decision, a readiness potential preceded the decision, as in Libet’s experiments. But when the decision mattered, no readiness potential was detected. 

“Overall then,” Mitchell writes, “Libet’s experiments have very little relevance for the question of free will. They do not relate to deliberative decisions at all, where readiness potential is not observed. Instead, they confirm, first, that neural activity in the brain is not completely deterministic and, second, that organisms can choose to harness the inherent randomness to make arbitrary decisions in a timely fashion.”

So much for “free.” We’ll examine what Mitchell has to say about “will” tomorrow.

On recognizing JEHOVAH’S Signature.

 Richard Dawkins, the Koala, and the Giraffe


Editor’s note: We are pleased to offer this Abstract from Part I of a new paper by Wolf-Ekkehard Lönnig, “Richard Dawkins, the Koala, and the Giraffe: How Evolutionists Overlook Signatures of Design, Part I.”

Abstract: Key Points of the Contents

Referring to science broadcaster Robyn Williams (Australia), Richard Dawkins believes that the koala’s pouch opens downwards due to its ancestry from a wombat-like animal instead of upwards as in the kangaroo — “a legacy in history.” A similar legacy, he assumes, also accounts for the recurrent laryngeal nerve in the giraffe.  
The Australian Koala Foundation contradicts him on this: The pouch “faces straight outwards rather than backwards” (emphasis added). The IFAW (Australia) agrees that, as compared with kangaroos, koalas “have a more centrally located opening.” And that is for good reasons: “The pouch protects young koalas, called joeys, from injury while the mother climbs among trees.” 
Now, Darwin correctly observed that “false facts are highly injurious to the progress of science, for they often long endure.” I consider the statement about the backwards opening pouch of the koalas to be “a false fact” to bolster neo-Darwinism — a false fact still widely repeated in many public statements. Check Google on the pouch of the koala. 
A series of links to videos and pictures shows the enormous differences between koala (Phascolarctos cinereus) and wombat (Vombatus ursinus) babies emerging from their pouches. This is likewise for good reasons: koalas are fully arboreal whereas wombats live on the ground and especially underground. 
As for the recurrent laryngeal nerve of the giraffe, see here.   
I remind the reader of a massive contradiction within the theory of evolution itself: “The genetic message, the program of the present-day organism…resembles a text without an author, that a proof-reader has been correcting for more than two billion years, continually improving, refining and completing it, gradually eliminating all imperfections” (Nobel laureate Francois Jacob). I give similar assertions by other authors in the text. And now, as a result of limitless, omniscient, and omnipotent natural selection over millions of years, “gradually eliminating all imperfections,” how are we to account for the koala’s imperfection, a pouch that “opens downwards, instead of upwards as in a kangaroo,” or an entirely superfluous long detour of the recurrent laryngeal nerve in the giraffe?
I cite thirty special adaptations in the arboreal/tree-living koala. Most of them are problematic from the perspective of gradual evolution, but, according to Dawkins, “evolution not only is a gradual process as a matter of fact; it has to be gradual if it is to do any explanatory work.” I subsume the overall system of synorganizations (the term used by evolutionist A. Remane), or “co-adaptations,” under the subheading “Signatures of Design in the Koala.”
Applying neo-Darwinism to the koala’s “two thumb adaptation” is shows — when starting with a hand/front paw like that of the wombat — the following result: After discussing several presuppositions and implications of gradualism, thousands of steps in millions of years would be necessary for the specific adaptation of the koala’s hand alone. And, just to emphasize the point: according to population genetics, here also “each new successful evolutionary step would imply the substitution of an entire Phascoarctos-like population.” 
In summary: According to evolutionary biologist Danielle Clode in her book about the koala (2023), “Koalas are singular creatures: idiosyncratic and inimitable. They are sometimes described as being ‘like bears,’ ‘like wombats,’ ‘like sloths,’ or ‘like pandas.’ They share some parallels, some traits with these creatures, but they are not in any way ‘like’ them. Koalas are simply unlike anything else we know of”

Now, if one is free to break away from the prohibitions of materialistic philosophy, one could, for example, accept the following reasoning. According to Austrian cell physiologist Siegfried Strugger, professor of botany at the University of Münster: “In comparison to the cell, all automation of human technology is only a primitive beginning of man in principle to arrive at a biotechnology.” Well, if the first steps on the path to the ingenious level of cybernetic complexities of the cell, i.e., the “primitive beginning” in Strugger’s formulation, demands conscious action, imagination, perception, intelligence, wisdom, mental concepts, spirit and mind — all being absolutely necessary for the basic start — how much more so does this have to apply to the origin of the thousand times more complex cybernetic systems of the many complex life forms themselves. And those include the specified and irreducibly complex structures inescapably necessary for the koala and countless other organisms

Darwinism is devolving?

 Is This a Paradigm Shift? 


My latest previous post, with David Klinghoffer, was about the “tipping point” in dissent from neo-Darwinism observed by Oxford physiologist Denis Noble, which he pin-pointed as occurring when the Royal Society convened in 2016 for the purpose of rethinking evolutionary theory. From Noble’s viewpoint, since 2016 defenders of neo-Darwinism have gotten very quiet, and young researchers in the emerging generation of scientists are happily working outside the framework of neo-Darwinism. 

Not long ago at all, that sort of change seemed like a distant dream. As Douglas Axe put it in 2016, the academe had become a “self-righteous monoculture,” and I think Axe’s comment expressed how many people felt: “Maybe this regrettable situation will change, someday.”

“Maybe…someday.” Implied was: But don’t hold your breath.

The Zeitgeist is dead.

But that’s always how it feels when a certain climate of opinion is dominant and in line with the current zeitgeist. The dogma seems utterly unshakeable. 

Until, one day, it doesn’t. C. S. Lewis (one of the most vehement critics of the zeitgeist qua zeitgeist) wrote

Nor can a man of my age ever forget how suddenly and completely the idealist philosophy of his youth fell. McTaggart, Green, Bosanquet, Bradley seemed enthroned forever; they went down as suddenly as the Bastille. And the interesting thing is that while I lived under that dynasty I felt various difficulties and objections which I never dared to express. They were so frightfully obvious that I felt sure they must be mere misunderstandings: the great men could not have made such very elementary mistakes as those which my objections implied. But very similar objections — though put, no doubt, far more cogently than I could have put them — were among the criticisms which finally prevailed. 

An idea sits on its glorious throne. None dare question it. All its critics are doomed to perpetual quackdom. And then — just like that! — the zeitgeist changes. Suddenly, that “indisputable” idea is old-fashioned, out-of-date. People forget that they ever believed in it. Another philosophy takes its place, and it seems indisputable.

If Noble is right, that’s happening with neo-Darwinism. And it may be too much to hope, but there is some evidence the shift goes even beyond neo-Darwinism. Even Darwinism itself (without the “neo-”), maybe even the overarching philosophy of methodological naturalism, could be approaching a fall from power. 

For example, Stephen Meyer perceives a shift in the public reception of intelligent design. In 2019, there was already a lot of interest in pro-ID content, but the responses tended to be very vicious. By 2023, the interest was still there, but the reactions seemed overwhelmingly positive. Meyer thinks this is a ripple effect from the deeper change that is underway, as arguments that have been percolating for decades begin to shift opinions in higher intellectual circles.

John West, meanwhile, has noted that opponents of intelligent design seem to be devolving in quality. Follow the downward trajectory from Darwin himself, to Stephen Jay Gould, to Richard Dawkins, to “loudmouth atheist” Jerry Coyne and P. Z. “hammer on the lunatics and idiots” Myers, to the likes of the YouTuber “Professor Dave” … The best of the best in the biology world just don’t seem that invested in attacking intelligent design or defending Darwinism anymore. 

Meanwhile, in the broader philosophical scene, two of the New Atheist “four horsemen of the apocalypse” (Dawkins, Dennett, Hitchens, and Harris) have passed away, and no one seems queued to replace them. Ayaan Hirsi Ali, once a contender for fifth horseman (or first horsewoman?), has converted to Christianity. Dawkins himself recently commented that he doesn’t want to be remembered for being “vehement and an atheist.” 

Something is changing. 

...Long live the Zeitgeist!

But let’s not get too excited. Just because the paradigms are shifting does not mean that intelligent design is going to suddenly take the throne. There are other options. Panpsychism is on the rise. Vitalist theories are coming out of the shadows. Denis Noble’s methodologically naturalist Third Way group are trying hard to carve out a theory of biology that is independent of both neo-Darwinism and intelligent design, placing their hopes in various versions of teleonomy (internal teleology) and autopoiesis (self-construction) as explanations for biological complexity. Whatever emerges victorious from the milieu is likely to be neither intelligent design nor old-fashioned neo-Darwinism — just as whatever emerges from the larger philosophical debates will probably be neither crude materialism nor old-fashioned religious theism. There are other options there, too.

On that note: the lack of will among Dawkins and his sort to fight against ID may be mostly due to the fact that the shifting winds of culture have tossed many of the ID people and Darwinists (including Richard Dawkins and Jerry Coyne) onto the same side of some of the most heated debates. It’s not 2005 anymore, and the center of the “culture war” is no longer between the Religious Right and the New Atheists. Ayaan Hirsi Ali, for her part, has said that one reason she became a Christian was because “secular tools alone can’t equip us for civilizational war.” 

Of course, not all proponents of intelligent design are religious, or politically on any particular side, or interested in civilizational wars. But atheist opponents of ID typically associate ID with religion, so if they find themselves on the same side as religious people in other ideological battles, they are naturally going to have less enthusiasm for attacking ID. 

Get ready for...something.

It isn’t necessarily a positive development. While it’s encouraging that unquestionable tenets of Darwinism are now becoming questionable, and while there are some genuinely encouraging signs of a new openness to the theory intelligent design in many circles, it’s important to realize that the new zeitgeist will not necessarily be any better than the old one. If old enemies are forced to be friends, that could be because they’re having to deal with something worse than either of them.

For example, a power-driven post-truth paradigm could be worse than the old materialist paradigm. Stephen Meyer recently commented that he feels in a sense like a kindred spirit with Richard Dawkins, because both men care intensely about the big questions of life. I saw what Meyer meant when I watched Dawkins’s recent debate with the ex-atheist Ayaan Hirsi Ali. Dawkins brushed aside the critique that the ideas he promoted might have undermined Western civilization with the response that, essentially, that was none of his business: as a scientist, he cared about what was true, consequences be damned. 

It sounded … old-fashioned. And that’s worrisome, because a post-truth paradigm is not likely to yield either truth or good pragmatic outcomes. If a post-truth attitude becomes entrenched in the new paradigm, we might look back nostalgically to the days when materialism was the main intellectual competitor. 

At any rate we don't get a choice.

Whatever the new paradigm looks like, ID theorists are going to want to be at the cutting-edge of engaging with it. Right now, it may be tempting to treat panpsychism, self-construction, teleonomy, and whatever else comes up as frivolous distractions from the real intellectual opponent of Darwinism. But I think that would be a mistake. 

As Denis Noble says, “neo-Darwinism is dead,” or at least dying. In the coming decades, the debate may be between, say, intelligent design and some sort of quantum physics-inflected marriage of scientism and spiritualism, not genuinely materialist, though haunted by the ghost of materialism. Because the coming victor is hard to see before it arrives, ID theorists need to be assessing new theories carefully as they emerge, not relegating them to mockery and dismissal. It would be a mistake to keep beating a dead horseman, and miss what’s coming up from behind.

Darwinists' problem is not with design but the designer.

 






New Study Reveals How the Shape of My Nose Arose




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.”

A theory of devolution?

 Is Adaptation Actually a Fight to Stay the Same?


On a new episode of ID the Future, host Casey Luskin talks with Eric Anderson on location at this year’s Conference on Engineering and Living Systems (CELS). The two discuss an intriguing new engineering-based model of bounded adaptation that could dramatically change how we view small-scale evolutionary changes within populations of organisms. In presenting his argument for natural selection, Charles Darwin pointed to small changes like finch beak size and peppered moth color as visible evidence of an unguided evolutionary process at work. Many have adopted this perspective, quick to grant the Darwinian mechanism credit for micro-, if not macro-, evolution. But Anderson and other attendees at the CELS conference are starting to promote a different view. “We need to stop saying organisms are partly designed,” says Anderson. “We need to view them as deeply designed and purposeful, active and engaged in their environments, and capable of adapting within their operating parameters.” To get a fascinating glimpse of this novel approach to biology, download the podcast or listen to it here .

On professor Dave and the bacterial flagellum

 Answering Farina on Behe’s Work: Bacterial Flagella


In a previous article, I began a series of four responses to YouTuber Dave Farina (aka “Professor Dave”) about his video reviewing Dr. Michael Behe’s three books. Here I will turn my attention to Mr. Farina’s comments regarding bacterial flagella.

In relation to the flagellum, the video complains about Behe’s “dishonest usage of terminology pertaining to machinery,” including phrases such as “outboard motor,” “drive shaft,” “universal joint,” “bushings,” and “clutch and braking system.” In reality, this terminology is used widely in the scientific literature. It’s not unique to Behe. On the contrary, in reference to flagella, the literature is full of such terms including “motor”,1 “drive shaft,”2 “universal joint,”3“bushing,”4 and “clutch.”5 The word “machine” itself has a wide circulation.6 Is Farina going to charge the entire flagella research community with dishonesty as well?

Co-option Scenarios for the Origins of Bacterial Flagella

According to the video, “A flagellum that merely twitches instead of rotating smoothly would also produce motion and thus could be selected for.” But a type IV pilis, which enables twitching motility (a form of bacterial translocation over moist surfaces), is very different from a flagellum. Twitching motility occurs by extension, tethering, and retraction of the type IV pilus, which functions in a manner akin to a grappling hook. A flagellum, on the other hand, rotates as it is driven by a proton motive force across the cell membrane. The assembly mechanisms of pili and flagella are also quite different.


The video complains that Behe fails to acknowledge the existence of alternative flagellar systems that are simpler than the model system found in Salmonella species and Escherichia coli. However, the fact that an alternative system lacks a specific component that is essential in another system does not mean that the former lacks an alternative mechanism for achieving the same outcome. The most robust concept of irreducible complexity understands it as a property of a system that is contributed to by multiple subfunctions, the removal of one of which causes the overall system to effectively cease performing its job. Note that each individual subfunction could, in principle, be performed by multiple protein components. Likewise, a single protein component could perform more than one of those subfunctions. Furthermore, the identity of the specific components performing each respective subfunction could differ from one organism to the next. It is therefore not the identity of the structural parts that is important in an irreducibly complex system, but rather the essential functions that need to be performed in order for a higher-level objective to be realized.


Moreover, pointing to homologues of flagellar proteins does not undermine the argument from irreducible complexity, since co-opting those proteins to produce a flagellar system requires multiple co-incident changes in order for the new system to be realized. For example, flagellar-specific proteins would not confer a selective advantage until incorporated into the flagellar system. But the necessary proteins that serve roles in other systems will not become incorporated into the flagellar system before these flagellar-specific proteins arise. This is quite aside from the need to have complementary protein-protein binding interfaces, as well as a choreographed assembly system to ensure that the proteins are assembled in the appropriate order.

Resurrecting a Flagellum

In a 2016 article at Evolution News, Behe asks, 

W]hy doesn’t [Kenneth Miller] just take an appropriate bacterial species, knock out the genes for its flagellum, place the bacterium under selective pressure (for mobility, say), and experimentally produce a flagellum — or any equally complex system — in the laboratory? (A flagellum, after all, has only 30-40 genes, not the hundreds Miller claims would be easy for natural selection to rapidly redesign.) If he did that, my claims would be utterly falsified. But he won’t even try it because he is grossly exaggerating the prospects of success.

The video by Farina comments

hilariously, [Behe] is oblivious to the fact that this precise experiment was carried out the year before. Here’s the paper. Gene deletion produced two strains of bacteria with no flagellum. They then introduced selective pressure for motility by depleting the nutrients in the colony. Within 96 hours, both strains had regenerated flagellar motility by a pathway involving two successive point mutations in genes that served other purposes.

However, the paper that Farina cites7 does not do this at all. Not for the first time with this video, I wonder if he has in fact read the paper. All that the researchers deleted was the flagellar master switch protein, FleQ, in Pseudomonas fluorescens. After a few days of incubating the bacterial cells on Petri dishes, they reacquired their ability to grow flagella. The genetic basis for this reactivation of the flagella is that another master switch protein, NtrC, that is a structurally similar homolog of FleQ — responsible for turning on genes involved in nitrogen metabolism — already had the ability, to some extent, to cross-bind to the promoter usually bound by FleQ. When produced in excess, as a result of a broken regulator, NtrC was thus able to drive flagellar synthesis. As a consequence of this mutation, the bacterial cell lost its ability to regulate its nitrogen metabolism genes. An article in The Scientist describes this research:

But while the re-evolved flagella enabled the bacteria to access food supplies at the farthest reaches of the Petri dish, the ability came at a price. ‘The bacteria that became much better at swimming were much worse at nitrogen regulation,’ said Johnson. However, she added, ‘sometimes the advantage can be so great that it’s worth paying that cost because otherwise you die.’

Thus, contrary to the Farina video’s claims, this paper does not document the de novo evolutionary origins of a bacterial flagellum at all — far from it. In fact, Behe has already addressed the paper here.

The Waiting Times Problem

In 2004, Michael Behe and David Snoke published a paper in the journal, Protein Science.8 About this paper, Farina has three complaints. The first complaint is that, “Behe and Snoke found that the target sequence did actually evolve, in population sizes and timeframes that are entirely realistic, and if anything, quite small compared to real-world populations. The paper literally proves them wrong and they somehow count it as a win anyway.” Farina mentions Behe’s expert testimony at the 2005 Kitzmiller v. Dover trial:

When questioned about his 2004 paper, Behe tacitly acknowledged that the population size in their model was orders of magnitude smaller than real-world bacterial populations, which had the effect of vastly underestimating the rate at which such “irreducible” traits could evolve… In one striking exchange, Behe acknowledged a paper which indicated that there are more prokaryotes in a single ton of soil than in his model population, and that there is a lot more than one ton of soil on Earth.

However, this objection stems from Farina’s misreading of the paper. As Behe himself explains in the very transcript that Farina cites, “forming a new disulfide bond might require as few as two point mutations. But forming other multi-residue features such as protein-protein binding sites might require more.” The graph below (figure 6 of the paper) shows Behe and Snoke’s estimate of the time to fixation (along the y-axis) versus the number of substitutions needed for a new feature to evolve (along the x-axis). On the top axis, values for the needed population sizes are given. The point is that, as the number of needed co-dependent mutations increases, so too does the needed population size and waiting time to fixation.



As Behe and Snoke explain in the paper, in a scenario where three substitutions are required for a novel feature to arise, a population size of roughly 1011 individuals is necessary for it to become fixed over the course of 108 generations (108 generations is marked as a horizontal bar on the figure). If the complex trait in question requires even more substitutions, it would require considerably more time. If six mutations were needed, the average population size required for it to become fixed in 108 generations would be on the order of 1022 individuals. Given that 1030 is a plausible estimate of the number of microorganisms on the entire planet9, these numbers become prohibitive very quickly.

The second complaint is that, “In their model, Behe and Snoke permitted only single-base mutations and natural selection — no recombination, no duplications beyond the initial presumed one, no other evolutionary changes.” But the authors explicitly say that “Because the model presented here does not include recombination, the results can be considered to be most applicable to a haploid, asexual population.” Nonetheless, they do note in the conclusion to their paper that “the results also impinge on the evolution of diploid sexual organisms,” since large multicellular organisms have much, much smaller population sizes than bacteria. If the evolution of complex features is difficult for microorganisms (with their massive population sizes and short generation turnover times), how much more so for large animals? Though one might counter, in the case of diploid sexual species, that recombination allows for neutral mutations to occur separately in a population and to later combine by sexual recombination, Christiansen et al. have shown, in a paper published in Theoretical Population Biology, that “Recombination lowers the waiting time until a new genotypic combination first appears, but the effect is small compared to that of the mutation rate and population size” (emphasis added).10

Finally, Farina complains that “They also specified a pre-determined target sequence and only considered the simulation to have been ‘successful’ if that specific target evolved.” But this is incorrect. Rather, the paper provides estimates for how many organisms would be required, and over how long a time frame, for multiple co-dependent mutations (none of which by themselves confers an advantage) to become fixed in a population.

Everyone's favourite contrarian is at it again.

 New! Philosopher and Mathematician David Berlinski on “Science After Babel”


Polymath and raconteur David Berlinski is at it again, challenging the shibboleths of contemporary science with his inimitable blend of deep learning, close reasoning, and rapier wit. His new book, Science After Babel, reflects on everything from Newton, Einstein, and Gödel to catastrophe theory, information theory, and the morass that is modern Darwinism. The scientific enterprise is unarguably impressive, but it shows no sign of reaching the empyrean heights it seemed to promise a century ago. “It resembles Bruegel’s Tower of Babel,” Berlinski says, “and if it suggests anything at all, it suggests that its original plans have somehow been lost.” Science endures. Scientism, it would seem, is guttering out.

We will be featuring excepts, commentary, and conversations with Dr. Berlinski in days to the come. Order your copy now. And enjoy some of the advance praise the book is already receiving!

Advance Praise

Many will read this book for the close, elegant reasoning, the astonishing erudition, or the mordant analysis. I confess I read it for the prose. “Vast sections of our experience might be so very rich in information” — I quote here from the discussion of our limited ability to define complexity — “that they stay forever outside the scope of theory and remain simply what they are: unique, ineffable, insubsumable, irreducible.” See what I mean? Nobody but David Berlinski has ever employed such sweet, gorgeous prose in writing about science.

PETER ROBINSON, MURDOCH DISTINGUISHED POLICY FELLOW AT THE HOOVER INSTITUTION AND FORMER SPEECHWRITER TO PRESIDENT RONALD REAGAN

Whether deconstructing the latest theory of everything or dishing on scientists and mathematicians he has known, whatever David Berlinski writes is delightful and profitable to read!


MICHAEL BEHE, PROFESSOR OF BIOLOGICAL SCIENCES, LEHIGH UNIVERSITY, AUTHOR OF DARWIN’S BLACK BOX, THE EDGE OF EVOLUTION, AND DARWIN DEVOLVES

If I were picking two books to be required reading for every college student in the United States, Science After Babel would be one. A striking and beautiful and absolutely necessary book. David Berlinski at his spectacular best.

DAVID GELERNTER, PROFESSOR OF COMPUTER SCIENCE, YALE UNIVERSITY

Science After Babel is a literary triumph. In it, David Berlinski masterfully exposes the hubris of scientific pretensions with a wit that dances deftly between the lines, unveiling profound insights with a refreshing candor. This book testifies to the author’s penetrating intellect, inviting readers to reconsider the limits of scientific authority and reject facile invocations of science that demand assent at the expense of compelling evidence and rigorous thought.


WILLIAM DEMBSKI, MATHEMATICIAN, PHILOSOPHER, AND FORMER HEAD OF THE MICHAEL POLANYI CENTER AT BAYLOR UNIVERSITY; AUTHOR OF MULTIPLE GROUNDBREAKING WORKS ON THE THEORY OF INTELLIGENT DESIGN, INCLUDING THE DESIGN INFERENCE (CAMBRIDGE UNIVERSITY PRESS, 1998)

Berlinski speaks wittingly as an insider to the sciences and their recent history. As a historian-philosopher of science, I recognize numerous valuable insights in this collection of arguments and memories. He captures the wonder of scientific inquiry without misplaced worship of speculative pronouncements made in its name. Berlinski is the most enjoyable antidote to scientism I know.


MICHAEL KEAS, LECTURER IN THE HISTORY AND PHILOSOPHY OF SCIENCE, BIOLA UNIVERSITY, AUTHOR OF UNBELIEVABLE: 7 MYTHS ABOUT THE HISTORY AND FUTURE OF SCIENCE AND RELIGION

Dr. Berlinski explores everything from the complicated spawning behavior of salmon and the problems with the RNA World hypothesis to various acute challenges to modern evolutionary theory, including the Cambrian explosion, molecular machines, and the failure of punctuated equilibrium. As he shows, trouble is brewing for Darwin on other fronts as well — population genetics, taxonomy, behavioral psychology, and the philosophy of biology, to name just a few. In total, Science After Babel is a lively mix of deep scientific knowledge, literary skill, and humor. The work reveals why scientism’s contemporary tower of babel has failed to reach the heavens. I highly recommend the book and hope it is widely read.

OLA HÖSSJER, PROFESSOR OF MATHEMATICAL STATISTICS, STOCKHOLM UNIVERSITY

In Science After Babel David Berlinski takes critical scholarly aim at many current day “scientific truths” — more properly shibboleths — including Darwinism, reductionism, the Standard Model of particle physics, and “talking” chimpanzees; and he shows how much nonsense often passes as secure scientific knowledge. Neo-Darwinism he describes as “empty,” and in discussing the Standard Model he comments wryly, “Theories come and go.” He also takes aim at a vast constellation of recent authors, including cosmologists Brian Greene and Lawrence Krauss, biologist Stephen Jay Gould, and philosopher of biology Michael Ruse.


The book is a delightful read delivered with great wit and erudition. We are treated to unique recollections — of his drinking coffee in Paris with René Thom, the founder of catastrophe theory; of the insane driving, also in Paris, of his friend, the mathematician, polymath, and leading French anti-Darwinist Marcel Schützenberger; and of a conversation with Noam Chomsky. Altogether the book represents an extraordinary and absolutely fascinating tour de force touching on topics as diverse as medieval Islamic astronomy and the great twentieth-century mathematician John von Neumann’s reflections on the role of chance in evolution. The text is interspersed throughout with some beautiful descriptive writing — Mount Rainer’s snow glimpsed flying out of SeaTac was “silent, sweeping, silvery, still, serene.”


The book is a stunning intellectual achievement. Few authors could have written such a far-reaching, in-depth critique of so many current philosophical and scientific beliefs. Science After Babel is mandatory reading for anyone interested in a critical assessment of much current scientific thinking. No other recent publication comes close, and unquestionably this brilliant book establishes David Berlinski as one of the leading intellectuals of our time.

Dave Farina: team atheism's LVP?

 Atheists Review Professor Dave’s Debate Performance


As someone who purports to educate others about science, Dave Farina has strengths and weaknesses. With 2.48 million subscribers on YouTube, Mr. Farina of “Professor Dave Explains” has a style that many find gratifying. As Professor James Tour said in their debate on the origin of life, Professor Dave has “tremendous reading skills” — he can read from a script, on YouTube or in a debate, with fluency and confidence. What Farina apparently can’t do, as Tour also noted, is “speak chemistry” on his own, when challenged and not using a script as a crutch. It also seems he can’t write chemical formulas, relevant to abiogenesis, on a blackboard with ease. Weak professional training may have something to do with his reliance on mindless sneering and insults. That’s my take.
          
“Do Better Next Time, Dave”

Of those who enjoy Farina’s style of juvenile personal abuse, I guess that most are atheists — by which I mean no disrespect to thoughtful atheists or agnostics! So I was curious what atheists made of his performance against Dr. Tour. In the comments section below the debate on YouTube, we find:

Keith Williams: “I’m an atheist, however, Farina’s smug and snide attacks on Tour throughout this debate, disgusted me. I may disagree with Tour’s mission, however, no one can ignore his considerable contribution to science.”

Artha Peterson: “I wonder why an actual abiogenesist won’t debate him [meaning, Tour]? That’s a serious question. Someone who actually can do the chemistry, unlike Dave. That would be the way to silence Tour on that topic forever. And yes, I am an atheist and yes I believe in abiogenesis.”

Lars Cade: “I’m an atheist and am already quite aware of the many ways in which Tour ignores or misrepresents data in his futile attacks on abiogenesis research, but he did far better in this debate than Farina. He laid out his definitions and stuck to the data and the topic. Because this is a very technical field, that’s all he needed to ‘win’ the debate. Do better next time, Dave.”

CaseAgainstFaith1: “Hi. I’m an atheist and I attended in person. Now I have not the slightest clue about the relevance of many things brought up during the debate. Like I have no clue about the 2,5 vs 3,5. I can say that Dave’s constantly calling Dr. Tour a liar and also insulting the audience was not helpful. Dr. Tour’s screaming wasn’t helpful either. But if I had to pick a winner I am afraid I would give it to Dr. Tour.”

thatwmckid: “I’m an atheist and I actually agree with James Tour.”

The Cambrian explosion is a thing?

 FAQ: The Cambrian Explosion Is Real, and It Is a Problem for Evolution


An email correspondent who is friendly to intelligent design (ID) recently wrote us asking how to respond to common objections to ID arguments about the Cambrian explosion. He was engaged with an interlocutor was making all kinds of contradictory “throw everything at the wall and see what sticks” objections that were simply factually inaccurate and are belied by mainstream scientific experts.  

Stephen Meyer addressed these points in detail in Darwin's Doubt with thoroughly researched arguments well backed by the scientific literature. This made it very easy to defend his arguments, which we’ve done across numerous Articles here on Evolution News. The points made below by our friend’s interlocutor are simplistic and don’t reflect what leading Cambrian experts really think. But they are very common objections and so we compiled this FAQ to help address common misconceptions about the Cambrian explosion. 

Claim: “The Cambrian Explosion was not a geologically short event but really took millions of years. 

Response: “How ‘Sudden’ Was the Cambrian Explosion? Nick Matzke Misreads Stephen Meyer and the Paleontological Literature; New Yorker Recycles Misrepresentation”

Claim: “There was complex animal life before the Cambrian so it does not represent the origin of many types of animals.”

Steve Meyer addressed this topic extensively in Chapters 2, 3, and 4 of Darwin’s Doubt, and Figure 2.5 in his book is a thoroughly researched and conservatively argued take on exactly how many animal phyla predate the Cambrian period and how explosive the Cambrian explosion was. Bottom line? At best only three animal phyla arose in the Precambrian and some twenty arose in the Cambrian period. But given problems with many claims of Precambrian animal fossils — especially bilaterian animals — the Cambrian period is probably even more explosive than that. For detail see:

“Let’s Help ‘Professor Dave’ Understand the Precambrian”
“Was Kimberella a Precambrian Mollusk?”
“On the Cambrian Explosion, Keith Miller’s BioLogos White Paper Falls Short”

Claim: “The Cambrian explosion is an artifact of an imperfect fossil record because in the Cambrian there are more fossil deposits to allow for soft-bodied fossils to be preserved, but these don’t exist in the Precambrian.

As Graham Budd and Sören Jensen state, “The known [Precambrian/Cambrian] fossil record has not been misunderstood, and there are no convincing bilaterian candidates known from the fossil record until just before the beginning of the Cambrian (c. 543 Ma), even though there are plentiful sediments older than this that should reveal them.” Thus they conclude, “The expected Darwinian pattern of a deep fossil history of the bilaterians, potentially showing their gradual development, stretching hundreds of millions of years into the Precambrian, has singularly failed to materialize.”

Claim: “The Cambrian explosion is an artifact of the fossil record because climatic or oceanic chemical changes allowed for a geologically-speaking rapid diversification in life.”

First, we need to understand that lots of new genetic information was needed for the animals that arose in the Cambrian explosion. See: 

“Groundbreaking Paper Shows Thousands of New Genes Needed for the Origin of Animals”
“Scientific Paper Reaffirms New Genes Required for Cambrian Explosion”
“Did the Origin of Animals Require New Genes?”

Second, we need to understand that climatic/oceanic chemical changes don’t explain the origin of the information needed for Cambrian explosion. This is a very common argument and it doesn’t hold up — we’ve addressed it so many times it’s hard to find all the places! But here are a few: 

 “As an Explanation of the Cambrian Explosion, the Oxygen Theory Takes a Lethal Blow”
“Sick of the Oxygen Theory of the Cambrian Explosion? Here’s the Cancer Theory”
“So Explaining the Cambrian Explosion Is All About the Oxygen, Is It?”
“Cambrian Animals? Just Add Oxygen
“ABC News Says ‘Darwin’s Dilemma May Be Solved’: What, Again?”
“Low Oxygen Suffocates Darwinian Explanations for the Cambrian Explosion“
Explaining Life’s ‘Great Leap Forward’: Now It’s Nitrogen“
“Here’s a Bubble That’s Ready to Burst: Oxygen as an Explanation for the Cambrian Explosion“
“Jerry Coyne Notwithstanding, as an ‘Explanation’ for the Rise of Complex Animal Life, Oxygen Is Now Eliminated from the Running”
“To Create Cambrian Animals, Whack the Earth from Space“
“Teamwork: New York Times and Science Magazine Seek to Rebut Darwin’s Doubt”
“Did the Early Oceans Contain Oxygen?“
“Does Lots of Sediment in the Ocean Solve the ‘Mystery’ of the Cambrian Explosion?”

Claim: “The Cambrian explosion was not a real event and reflects a combination of many factors that make it appear as if animals appeared suddenly, but this really did not happen.”

This claim is not true and it is contradicted by many authorities on Cambrian paleontology and paleobiology:

“Erwin and Valentine’s The Cambrian Explosion Affirms Major Points in Darwin’s Doubt: The Cambrian Enigma Is ‘Unresolved’”
“Untangling “Professor Dave’s” Confusion about the Cambrian Explosion”
“Darwin Defenders Love Donald Prothero’s Ranting Review of Darwin’s Doubt“
I’ll close this little FAQ with a telling quote from Dutch biologist Martin Scheffer on the reality of the Cambrian explosion, from a Princeton University Press book:

The collapse of the Ediacaran fauna is followed by the spectacular radiation of novel life-forms known as the Cambrian explosion. All of the main body plans that we know now evolved in as little as about 10 million years. It might have been thought that this apparent explosion of diversity might be an artifact. For instance, it could be that earlier rocks were not as good for preserving fossils. However, very well preserved fossils do exist from earlier periods, and it is now generally accepted that the Cambrian explosion was real. 

MARTIN SCHEFFER, CRITICAL TRANSITIONS IN NATURE AND SOCIETY (PRINCETON UNIVERSITY PRESS, 2009), 169-170.

There are of course other possible objections to Meyer’s arguments regarding the Cambrian explosion and we’ve probably addressed those somewhere too. But these are by far the most common objections — I hope this little FAQ is helpful in responding to them!

Origin of Life science needs an intervention?

 ASCB Addresses Problem of False Science


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.

The sublime logistics of the human body vs. Darwinism.


The fossil record's flying reptiles may have eaten Darwinist's homework

 Fossil Friday: The Explosive Origin of Flying Reptiles in the Mid Triassic


This Fossil Friday features the gliding reptile Sharovipteryx mirabilis from the Mid Triassic of Central Asia.

Within only two million years of the Mid-Triassic era (about 230-228 million years ago) there was a sudden appearance of a large diversity of gliding and flying reptiles, such as Sharovipteryx with wings on the legs, Mecistotrachelos and the unrelated Kuehneosauridae with a gliding membrane across lateral rib-like projections, Longisquama with long feather-like scales on the back, and the earliest pterosaurs such as Preondactylus with bat-like wings supported by a single enlarged finger.

Considerable Re-Engineering

All these very different solutions for gliding and active flight required considerable re-engineering of the tetrapod body plan, and such biological novelty arguably required new and highly specific genetic code. Such specified information cannot be produced by blind mechanisms and certainly not in such a short window of time of only two million years, which corresponds to just about half the average longevity of a vertebrate species.

Personally, I am quite sympathetic to the dissenting view of my paleontologist colleague Simon Conway Morris, who suggested that evolution does not work through a blind and random mechanism, but rather like a search engine that searches for pre-existing platonic forms in a constrained hyperspace of biological possibilities. However, this would no longer be Darwinian evolution but a highly teleological process and thus a kind of intelligent design combined with platonist idealism as metaphysics.

Whatever the mechanism of design may have been, the abrupt origin of flying reptiles is just one example within a kind of carpet bombing of biological explosions during the Triassic era, when many new orders and families of metazoan animals suddenly appeared after the end-Permian mass extinction event. This has been called the Early Triassic Metazoan Radiation, and includes marine invertebrates (e.g., bivalves and ceratite cephalopods), insects (e.g., coleopterans and dipterans), 15 different families and body plans of marine reptiles (Bechly 2023), as well as the first representatives of modern terrestrial tetrapod taxa that appeared suddenly within a short window of time between 251-240 million years ago (Ezcurra 2010). The latter include the first dinosaurs (Nyasasaurus), the first lizard-relatives (Lepidosauromorpha such as Paliguana), the first croc-relatives (Crurotarsi such as Ctenodiscosaurus), the first mammal-like animals (Mammaliaformes such as Haramiyida), and allegedly the first turtles (Pappochelys) even though this is more dubious (Bechly 2022).

Goal-Directed and Intelligent

The well-known paleontologist Peter Ward, who is an ardent Darwinist and a strong opponent of intelligent design theory, explicitly acknowledged that “the diversity of Triassic animal plans is analogous to the diversity of marine body plans that resulted from the Cambrian Explosion. It also occurred for nearly the same reasons and, as will be shown, was as important for animal life on land as the Cambrian Explosion was for marine animal life” (Ward 2006:160). I totally agree that all these explosions occurred for the same reasons and by the same causes, which must have been goal-directed and intelligent.

Yet another nail in the coffin of Darwinism's "simple beginning"


From the selfish gene to kinship in one easy lesson?

 Evolutionists: We Now Have Empirical Evidence For the Evolution of Kin Recognition


In a new Study out of the University of Liverpool evolutionists now say they have found empirical evidence that a genetic complex, involving dozens of protein-coding genes related to altruism, can evolve. Such a finding would be truly ground-breaking given that, at least up until now, the evolution of even a single protein has been found to be scientifically unlikely. It would be astonishing if now evolutionists have overturned a substantial body of work establishing molecular evolution to be effectively impossible. But of course evolutionists have done no such thing. There was no finding of molecular evolution, no new proteins or genes, no empirical evidence, nothing. Just another ridiculous claim made by evolutionists. It’s the same old pattern—evolutionists look at profoundly complicated biological structures, assume they evolved, and then claim they have found evidence of evolution.

Altruistic behavior creates many problems for evolution. One problem is the starting point: kin recognition, evolutionists unsuccessfully tried to explain altruism using the concept of kin selection, and while that creates many scientific problems, you can’t even get to kin selection without kin recognition. How do animal siblings or cousins recognize each other.

The new study out of the University of Liverpool has found a genetic basis for kin recognition. It is a genetic complex of a couple dozen protein-coding genes and the problems with this are several.

First, it means that kin selection hinges on several proteins working together. Evolving a single protein is, from a scientific perspective, so unlikely as to be effectively impossible. But here evolution needs several proteins. Evolve just one protein and you still don’t have kin recognition. You would have to evolve several others, so the problem is even more difficult.

Second, the genetic cluster is species-specific. Apparently there is no common kin recognition mechanism across the vertebrates as evolutionists had assumed. Of course evolutionists had assumed this, for to have different mechanisms, particular to species or groups of species, would make their theory even more absurdly improbable. Kin recognition would have to re-evolve, in various ways, over and over. Well that is exactly what this new finding is suggesting. As usual, biology shows specific, particular, solutions that are unique to one or a few species, rather than falling into the expected common descent pattern.

Once again, common descent fails to serve as a useful guide. And once again evolutionists, in spite of the science, claim more proof for their theory.
