Why gradualism is a loose cannon on Darwinism's deck

 

The undead continue to prowl Darwinism's badlands.

 Darwin’s Zombies Are Still Shambling Along

David Coppedge

The Icons of Evolution that Dr Jonathan Wells wrote about 24 years ago have not been put out of our misery. Like denizens of Zombie Science, they keep reappearing in popular science articles, cartoons, and even scientific journals. The perpetrators should know better. There is no excuse for perpetuating the mythic fables that Darwinians have used to popularize just-so stories of how natural selection supposedly works (but doesn’t under the spotlight).

Two of the icons appeared in publications recently. The old stories are retold without remorse, in spite of the fact that new evidence contradicts them.

The Peppered Myth Still Walks

Perhaps word of the falsification of the peppered myth has not yet reached the Far East. That’s doubtful, but the University of Michigan co-authors of a new study that could have told their colleagues in Singapore and Japan not to write as if the peppered myth is still a valid case of natural selection. News from the University of Singapore says bluntly,

Lepidopterans (butterflies and moths) exhibit a splendid diversity of wing colour patterns, and many species display black and white, or dark and bright, wing colour pattern variants associated with the presence and absence of melanin. Many of these wing colour pattern variants are textbook examples of natural selection and evolution. Iconic examples include the rapid increase in frequency of the melanic form of the British peppered moth Biston betularia, driven by the sootier and darker environment caused by carbon burning and industrialisation in the late 1800s in the United Kingdom, and the mimetic radiation of Heliconius butterflies, among others. 

Can this be dismissed as a minor slip? Did they perhaps mean that peppered moths “were” or “used to be” textbook examples of natural selection and evolution? Clearly not; the press release includes a YouTube video by Antonia Monteiro, one of the co-authors of the paper in Science.1 The narrator calls it a “classic Darwinian story of natural selection.” The video repeats the peppered myth in all its gory, hoary just-so story form, claiming that the coloration provided camouflage as the moths rested on tree trunks and that nature selected them because color changes helped them evade predators — false claims made by Kettlewell and never substantiated since. We remind everyone that both light and dark moths are variants of the same species: Biston betularia.There was no origin of species. In the quote, they state that “many species” display dark and light “variants” yet they call these “textbook examples of natural selection and evolution.” Within species? How is that kind of selection going to get brains from bacteria?

What’s ironic is that the scientific findings undermine natural selection as the cause of the color variants. As I mentioned in a recent article, researchers have been finding that microRNAs and noncoding RNAs are likely responsible for the color changes — not mutations to the cortex gene or to any other gene. This new paper identifies a particular microRNA named mir-193, a derivative of ivory, a long noncoding RNA (lncRNA), as the regulatory switch that turns on light or dark coloration. The outcome depends on the switch’s interaction with ivory or with the mRNA transcript of another gene called ebony. 

The video illogically says, 

It appears that the mutations that regulate the presence and absence of ivory and mir-193 across many different species are the go-to mutations that are repeatedly used to create the dark/light polymorphisms in insects.

Do the moths (or a blind Selector) “use” mutations to “create” on purpose? These are not genetic mutations assumed in neo-Darwinism. They are switches present in all butterflies that can produce one polymorphism or another. In the case of peppered moths, both the dark and light forms existed before and after the industrial revolution. All the story demonstrated, therefore, was “a shift in the proportions of two existing varieties of the same species,” as Wells stated in Zombie Science (p. 64). And it was not demonstrated, Wells goes on to say, that the moths routinely rest on tree trunks or that predation by birds altered the proportions of the pre-existing varieties. 

This is hardly a classic case of natural selection, therefore, and certainly not an instance of the origin of species. The new research merely finds a regulatory switching mechanism that can produce dark or light polymorphisms within species. MicroRNA transcripts of noncoding RNAs are likely implicated in variability in other animals as well.

Overall, our study identified a miRNA, processed from the primary transcript of a lncRNA, as the likely effector of a hotspot locus that underlies adaptive evolution in animals. This adds to a recent discovery of small noncoding RNAs being key regulators of adaptive flower color evolution and speciation. The burst of miRNA innovation at the base of Lepidoptera may have served as evolutionary raw materials to create a gamut of morphological diversity within this order, one of the most species-rich on earth.

This Is Not Your Grandpa’s Darwinism

The authors never mention genetic mutations, selection, inheritance, or fitness. The paper never says that phenotypic plasticity helps moths avoid predators. And Darwin the gradualist would have shuddered at any “burst of innovation” at the base of a taxonomic group. The authors did not witness a burst of innovation. They only asserted it. 

This and future investigations of noncoding RNAs will shed light on the long-standing hypothesis that it is the complexity of swiftly evolving noncoding components of the genome (cis-acting regulatory DNA elements and trans-acting noncoding RNAs), rather than the relatively static evolution of protein sequences, that drives organismal complexity

Here again they assert “swiftly evolving” parts of the genome without proof. The old gradualistic neo-Darwinism, updated for modern genetics, would only have produced “relatively static evolution of protein sequences” by mutations. Complexity within a species, genus or family because of regulatory elements is not the same as universal common ancestry due to natural selection of random mutations. How, then, can this be a “textbook example of natural selection and evolution” as the authors claim in the press release? The paper doesn’t even mention natural selection.

The authors do not say what cues — whether environmental or otherwise — trigger action by the mir-193 regulatory switch. They mention four times that the colors are “adaptive” in some way, but non-Darwinian interpretations are possible: genetic drift, or (as some ID researchers are proposing) internal engineering: i.e., switches that can be triggered by environmental cues. The return of the light-colored peppered moths after the industrial revolution suggests that the switching is reversible. Connecting the activity of miRNAs and lncRNAs to environmental cues sounds like a good follow-up experiment for non-Darwinian scientists.

The Miller Myth Still Walks

It the same issue, Science trotted out another zombie icon for celebration: the Miller experiment.2 In Darwinian style, Antonion Lazcano’s article, “On the origins of organisms,” praises both Aleksander Oparin and Stanley Miller. “The heterotrophic theory of the origin of life turns 100,” the subtitle announces triumphantly. Oparin’s 1924 book, The Origin of Life,

proposed that life had emerged in an oxygen-free primitive environment that led to the synthesis and accumulation of organic compounds that subsequently formed gel-like droplets from which the first heterotrophic organisms evolved. The volume became quite popular among student associations, workers’ clubs, and biology teachers, and the small edition quickly sold out, never to be reprinted. On its 100th anniversary, Oparin’s visionary work is worth revisiting.

Oparin the Marxist, who had been influenced by Ernst Haeckel, expanded his book for a 1936 edition whose 1938 translation was highly influential to Harold Urey. His PhD student Stanley Miller is pictured in a large photo standing by his spark-discharge apparatus.

Does Lazcano ever warn his readers that Oparin and Miller’s works have been demoted to irrelevant historical footnotes because the early earth likely had oxygen? Does he lament the fact that Miller used an improbable reducing atmosphere? Does he point out that the predominant product of the spark-discharge apparatus was tar that would have destroyed the desired products faster than they formed, had Miller not built a trap to separate them out? No; instead, he calls the experiment “spectacular” —

The 1938 English translation of Oparin’s second book played a seminal role in shaping Stanley L. Miller’s famous 1953 synthesis of amino acids and other organic compounds under possible primitive conditions. The spectacular results of Miller’s laboratory simulation marked the start of the laboratory phase of what we now call prebiotic chemistry.

Why Risky? And Useful to Whom?

Lazcano grants that “No scientific theory remains unchanged as time goes by, and the prebiotic soup remains a useful but risky metaphor.”

The fact that a number of biochemical components of contemporary forms of life can be synthesized nonenzymatically does not necessarily imply that they were also essential for the origin of life or that they were available in the primitive environment.

We do not know when, where, or how life appeared on Earth, but the current debates on the significance of extraterrestrial organic molecules, together with our laboratory reconstructions of primitive environments, are in themselves a recognition of the key role that prebiotic chemistry played in the processes that led to the emergence of the first life-forms.

Oparin and Miller had the right religion, in other words: materialism. They had the wrong atmosphere. They had the wrong ingredients. They interfered in the experimental design. But they had the right doctrine: some unknown form of “prebiotic chemistry” led to “the emergence of the first life-forms” — no intelligence allowed. 

For this reason — science notwithstanding — the mainstream media continues to allow these zombie icons to “shed light” on evolution, rising from the tombs, putting on Darwin costumes, holding up their sparking flasks, distributing samples of prebiotic soup to the townspeople as peppered moths flutter about their heads.

The fossil record on homoiothermic animals vs. Darwin.

 Fossil Friday: A Scientific Controversy About Warm-Blooded Animals

Gunter Bechly

This Fossil Friday features the exceptionally well-preserved fossil bird Nahmavis grandei from the Eocene Green River Formation of Wyoming, as an example for a fossil representative of warm-blooded animals. Nowadays, every high-school biology class teaches that mammals and birds, even though both are warm-blooded tetrapods, are not closely related and were derived from different reptilian-like ancestors. Their similar physiology is attributed to so-called convergent evolution, thus is claimed to have had an independent evolutionary origin. However, if generally anatomical, physiological, genetic, and behavioral similarities are mostly explained by common descent, why are all warm-blooded animals not grouped together as descendants of a common warm-blooded ancestor? Indeed, based on much earlier observations of John Ray (1693), Charles Darwin’s famous opponent at the British Museum for Natural History, the paleontologist Richard Owen (1866), who had coined the word dinosaur, had first suggested to group birds and mammals together in a taxon Haematothermia, based on their similar warm-blooded physiology.

This was mostly ignored by other biologists until about 120 years later, when the two maverick biologists Søren Løvtrup (1977, 1985) and Brian Gardiner (1982, 1993) took up the idea and again suggested that all warm-blooded vertebrates form a clade Haemothermia, thus birds and mammals would be most closely related sister groups. They both suggested that the complex physiological similarities are unlikely to be convergences and rather represent deep evolutionary homologies. Nobody less than the famous French vertebrate paleontologist Philippe Janvier (1984) even published a reconstruction drawing how a hypothetical ancestor of Haemothermia might have looked like (reproduced by Sivgin 2020). This went against a growing consensus among evolutionary biologists that mammals were derived from synapsid “mammal-like reptiles” like the Permian pelycosaurs, while birds were diapsids more closely related to dinosaurs and crocodiles as well as other living reptiles. Consequently, their suggestion was immediately met with harsh criticism (Benton 1985, 1991, Kemp 1988, Gauthier et al. 1988a, 1988b) and their “radical hypothesis” (Peters 2014) was ultimately rejected as absurd (Kuhn-Schnyder 2009). The reason were the numerous other similarities from skeleton to genomics (e.g., Janke & Arnason 1997) that rather supported the mainstream view.

Pterosaurs and Dinosaurs

However, it must be noted that Gardiner (1993) explicitly agreed that pterosaurs and dinosaurs are close relatives of birds, and “mammal-like reptiles” were relatives and ancestors of mammals. He simply included those reptile-like groups in Haematothermia, and indeed there has been considerable evidence accumulated in the past decades that they also were warm-blooded. Here is a quote from Gardiner’s (1993) abstract:

An exhaustive parsimony analysis of amniote phylogeny using 97 characters has substantiated the hypothesis that mammals and birds are sister groups. This deduction is further supported by parasitological and molecular evidence. The presumed importance of “synapsid” fossils in amniote phylogeny is questioned and it is concluded that they represent a transformation series which, when broken down into constituent monophyletic groups, does not support the separation of the Mammalia from the remainder of the amniotes. Fossil members of the Haematothermia include pterosaurs and “dinosaurs” (both stem-group birds) and Dinocephalia, Dicynodontia, Gorgonopsida and Therocephalia (all stem-group mammals). The Dromaeosauridae are the most crownward stem-group birds and the Morganucodontidae the most crownward stem-group mammals.

Thus, Gardiner (1993) rather suggested that Synapsida and Archosauria are sister groups, which is a hypothesis that is still endorsed by the highly controversial fringe paleontologist David Peters (2024) in his large reptile tree based on 2323 taxa and 236 characters.

Gardiner is said to still have embraced the Haematothermia hypothesis until later in his life (Naish 2008, 2012). Nevertheless, the idea of such a clade of warm-blooded animals was quickly buried and forgotten by the scientific community again, so that the work of Løvtrup and Gardiner is not even mentioned anymore in modern treatises on the origin of endothermy in vertebrates (e.g., Koteja 2004, Nespolo et al. 2011, Benton 2021, Grigg et al. 2022, Faure-Brac et al. 2024). After all, isn’t it really silly to just look at a superficial similarity like warm-bloodedness and ignore all the conflicting evidence. Yes, that might have been silly indeed, but it was not at all what Løvtrup and Gardiner did. Indeed they assembled substantial evidence for their Haematothermia hypothesis that went far beyond only a superficial similarity in physiology, but included a cladistic analysis of 28 specific similarities, of which even the most ardent critics recognized at least 8 as valid (Kemp 1988).

Also, other authors often admitted that birds and mammals share many similarities of the “cardiovascular, renal, gastrointestinal, endocrine and nervous systems” (Carvalho & Gonçalves 2011). Even more recently, a paper on the supposed convergences between birds and mammals published by Wu & Wang (2019) in the Proceedings of the Royal Society, confirmed these similarities and suggesting even more:

Extant birds and mammals share a number of highly similar characteristics, including but not limited to, enhanced hearing, vocal communication, endothermy, insulation, shivering, respiratory turbinates, high basal metabolism, grinding, sustained activity, four-chambered heart, high blood pressure, and intensive parental care.

A Very Incomplete List

Here is a very incomplete list of a dozen complex derived similarities shared by birds and mammals, which I stumbled upon during a quick survey of the recent scientific literature I made for this article:

Visceral endothermy or warm-bloodedness means that birds and mammals share the ability to maintain a stable internal body temperature, a characteristic crucial for active living in a wide range of environmental conditions (Nespolo et al. 2011). If this endothermy would be homologous in birds and mammals we should expect that they acquired this trait at the same time, which is exactly what we find (Benton 2021), allegedly based on a shared adaptation to nocturnality in their early evolution (Wu & Wang 2019). Of course, the warm-bloodedness correlates with high metabolic rates in birds and mammals, compared to most reptiles, supporting their increased energetic demand for sustained activity and thermoregulation.

Mammals and birds possess a four-chambered heart that efficiently separates oxygenated and deoxygenated blood, facilitating high metabolic rates required for endothermy. However it must be noted that a four-chambered heart is also present in crocodylians, who may have secondarily reverted to ectothermy (Grigg et al. 2022). With this knowledge I suppose that Gardiner would have decided to include crocs in his Haematothermia clade of synapsids and archosaurs.

Both birds and mammals posses integumental structures (feathers in birds and fur in mammals), made from keratin and originating from placodes that are homologous to reptilian scales, as specialized body coverings for insulation to reduce heat loss, which is of course a crucial adaptation for endothermy (Chernova 2005, Dhouailly 2009, Di-Poï & Milinkovitch 2016).

Even though very different in organisation, birds and mammals have the most complex lungs among vertebrates and a highly efficient respiratory systems that support their high metabolic demands (Meyer et al. 1981, Powell & Hopkins 2004, West et al. 2007).

Both birds and mammals exhibit relatively large brains compared to body size, particularly in regions associated with higher cognitive function, such as learning, problem-solving, and social behaviors. More specifically, only mammals and birds possess a well-developed neocortex, called dorsal ventricular ridge (DVR) in birds (UChicago Medicine 2012, Kebschull 2020, Stacho et al. 2020, Ball & Balthazart 2021). Apart from the increased relative brain size and highly laminar telencephalic areas, birds and mammals also share a complex cerebellar folding, enhancing motor control and coordination, as well as advanced auditory circuits capable of processing complex sounds (Striedter & Northcutt 2019).

Only mammals and birds have episodic-like memory (Rattenborg & Martinez-Gonzalez 2011, 2013).

Even though sleep was for decades considered to be exclusive to mammals and birds, it is meanwhile shown to be a widespread phenomenon in the animal kingdom. However, “REM sleep, the major source of dreams, and slow wave sleep are unique to mammals and birds” (AAAS 2015, Hayashi et al. 2015). 

Birds and mammals have specialized hearing mechanisms, including middle ear ossicles (ossicular chain) that transmit sound vibrations effectively, allowing for acute auditory sensitivity (Köppl 2011, Anthwal et al. 2012: fig. 1).

Both groups possess complex endocrine hormonal systems that regulate growth, metabolism, and reproduction. Actually, “birds produce homologues of the vast majority of mammalian hormones. These can have similar roles in birds and mammals.” (Scanes 2015). For instance, the thyroid and adrenal glands play essential roles in metabolic rate control, and prolactin controls seasonality in birds and mammals (Stewart & Marshall 2022).

Both birds and mammals engage in complex social behaviours, including cooperation, communication, intricate mating rituals and significant parental care, including prolonged juvenile periods and provisioning of food, which enhances offspring survival in challenging environments. Play behaviour was long considered to be unique to mammals and birds (Dinets 2023), but it has been meanwhile recorded from a few ectothermic animal species as well, but it is still only widely occurring and well-developed in birds and mammals.

A cladistic study of 16 ultrastructure characters of spermatozoa (Jamieson & Healy 1992) strongly supported the bird + mammal clade (Haemothermia) with three uniquely derived similarities, and did not substantiate the traditional grouping. This is significant because it is a totally independent source of evidence unrelated to warm-blooded physiology.

In spite of differential rates of transposable element accumulation “the genome size in mammals and birds shows remarkably little interspecific variation compared with other taxa.” The results of a study by Kapusta et al. (2017) imply that “DNA removal in both mammals and birds has proceeded mostly through large segmental deletions”, which has been called an “accordion model” of genome size evolution.

All these striking similarities would have to be considered as convergent adaptations, which were the result of similar selective pressures in birds and mammals that have led to the independent origin of these complex traits. So, both alternatives, the mainstream view and the Haematothermia hypothesis, imply a lot of convergences, so that many similarities cannot be readily explained with common descent. Ultimately, a bureaucratic counting of which alternative is supported by a few more similarities (see Kemp 1988) decides for evolutionary biologists, which common descent hypothesis is embraced and which is rejected as absurd. If you look at many of the publication dates of the references in my list above, you see that a lot more characters that would support Haematothermia have been discovered since the time of Løvtrup and Gardiner.

To be clear, I do not suggest that the Haematothermia hypothesis is a better alternative to the mainstream view, but rather suggest that the strongly conflicting data point to a deeper problem. In the view of us critics of neo-Darwinian evolution, the large amount of incongruent and conflicting evidence rather questions all alternatives and the very paradigm of common descent itself. Even though common descent may well still be true, either on a universal level or at least for more restricted groups, it cannot be convincingly demonstrated by just pointing to shared similarities. Those similarities would have to be overwhelmingly congruent and mostly point to the same nested hierarchy, if the story of a single tree of life would be true. But they don’t. Incongruent evidence is found abundantly in all groups and all levels of the taxonomic hierarchy. The theory of Darwinism made a prediction of similarities that neatly fall into a nested hierarchy without significant incongruence, but it failed the test by empirical data miserably. Other processes than common descent with modification have to account for the similarities and differences between organisms, and intelligent design definitely is a premier candidate.

Ignoring the Evidence

How do popularizers of Darwinism such as Richard Dawkins react? Unsurprisingly, they just ignore the evidence and boldly tell their gullible fanboys (and girls) that evolution is a proven fact because all data unambiguously suggest a single true tree of life. Is this mere ignorance or deliberate deception? The materialist-naturalist world view critically depends of Darwinian evolution and must defend it at all cost, even if it means that the facts have to be tweaked, fudged, and denied to fit the theory. And all critics must be silenced as dangerous science-deniers and peddlers of pseudoscience and evil religious superstition. More and more people no longer fall for this crude propaganda and rather follow the evidence wherever it leads. Isn’t this what science is all about, or at least should be?
