In a previous post I quoted an evolutionary biologist who recently gushed, "But what I aspire to be, more than anything, is an intellectual child of Charles Darwin." Statements such as that may have given you the impression that evolutionary biologists are people fixated on the teachings of one idolized hero, people who fail to properly study many deep topics that should be studied before anyone boasts of understanding human origins -- kind of like the fellow schematically depicted below.

The 2025 paper "Complexity myths and the misappropriation of evolutionary theory" by evolutionary biologist Michael Lynch is a paper that may tend to corroborate negative ideas you may have about evolutionary biologists. It is a paper full of hubris and crowing, combined with the clumsiest attempts to sweep under the rug or rhetorically minimize the ocean-sized reality of fine-tuned biological complexity. Along the way, the author makes some confessions that help discredit the central claims that dogmatists of his type like to make.
After its abstract the paper starts out by stating, "Enormous strides have been made in the biological sciences over the past century, and no subdiscipline has experienced greater advancements on the theory side than evolutionary biology." To the contrary, evolutionary biology is still chained to the clueless armchair-reasoning ideas of the nineteenth century biologist Charles Darwin. Evolutionary biologists have made very little progress beyond such erring ideas, and we should not count it as progress when such biologists strayed into the giant deception of making the false claim that DNA or its genes are a recipe, blueprint or program for making an organism or its cells.
Lynch takes the briefest of lame slaps at something called the Extended Evolutionary Synthesis or EES. The term is an umbrella term for a grab bag of ideas by not-very-contrarian scientists who have noticed how miserably bad today's evolutionary biologists are at explaining the vast complexity and organization in living organisms. Lynch's rebuttal consists only of the name calling of referring to the supporter of this EES as "a small but vocal group of proselytizers," combined with the claim that "virtually every point identified as ignored has been thoroughly evaluated in prior research." This is almost as lame as saying "you can't say I fail to explain biological complexity, because I mentioned biological complexity."
Lynch offers a criticism of a recent theory called assembly theory. Some of his points about the weaknesses of that theory are valid. I criticized the same theory in my post here.
Along the way, Lynch makes some confessions damaging to his cherished dogmas. He states that "there is no evidence that natural selection is in relentless pursuit of more complex molecules, cells, or organisms." But has not so-called "natural selection" been offered for roughly 179 years as the primary explanation for biological complexity, by evolutionary biologists such as Lynch? It almost sounds like Lynch is now hinting that such an explanation was incorrect.
In the very next sentence, Lynch offers what sounds like the lamest explanation ever for biological complexity, a "only one direction to go in" explanation. He states this: "Of course, today’s organisms are more complex than prior to the Last Universal Common Ancestor (LUCA), but there was only one direction to go four-billion years ago at the first dawn of cells." Similar reasoning might claim that well-built tall moon rockets can be built by tornadoes passing through junk yards, and claim that we should not be surprised by this on the grounds that "there was only one direction to go," the direction leading up towards the sky.
The claim of "only one direction to go" is false. Once organisms arise with a dependency on a huge library of chemical information in genes, there are two directions that can be traversed, one leading to greater functional complexity, greater organization and more impressive biological functionality, and the other leading to less functional complexity, less organization and worse biological functionality. Random mutations occur all the time, and a large fraction of such mutations tend to cause illness and dysfunction.
We then have this paragraph by Lynch:
"Microbes have been around for this entire period [4 billion years], and yet have not expanded in complexity. Given their enormous population sizes and short generation times, there were clearly adequate opportunities for the emergence of genomic, molecular, and cellular complexity should it have been at a selective premium. Yet, the origin of morphologically complex cells leading to eukaryotes was a singular event, and the vast majority of the Tree of Life remains prokaryotic. There are roughly 1030 prokaryotic individuals on Earth, three orders of magnitude more than unicellular eukaryotes, and ten orders of magnitude more than the total number of metazoan individuals (reviewed in ref. 19), hardly an observation in support of a determined march toward complexity."
The first statement is false, according to the standard account of biologists. According to their account, there first existed prokaryotic calls much more simple than the vastly more complex type of cells in human bodies, called eukaryotic cells. So, according to the standard account, there was an enormous leap in the complexity of microbes. So why is Lynch claiming "microbes...have not expanded in complexity"? Later in the same paragraph, he contradicts his earlier assertion by referring to the origin of eukaryotic cells. He has no Darwinian or gradualist explanation for this event, referring to it as "a singular event." The standard story among biologists is that this vast leap in organization occurred as a "once in the planet's history" event due to some fantastically improbable accident.
Ponder how ridiculous the last sentence is in the italicized quote above. Lynch states, "There are roughly 1030 prokaryotic individuals on Earth, three orders of magnitude more than unicellular eukaryotes, and ten orders of magnitude more than the total number of metazoan individuals (reviewed in ref. 19), hardly an observation in support of a determined march toward complexity." This is cover-up-the-complexity talk along the lines of "the microbes vastly outnumber the mammals, so we should not think life is so complex." Similar nonsense would claim that failed writers vastly outnumber writers such as Shakespeare, so we should not be too impressed by the works of Shakespeare.
The next paragraph is more cover-up-the-complexity nonsense. In one sentence Lynch makes the lame suggestion that we should not be too impressed by bursts of gene innovation in large animals, on the grounds that microbes had bigger bursts of gene innovation. Lynch also makes the false claim that large organisms only required "one new gene per 100,000" years. The claim is utterly unbelievable. Animal life is divided into about 30 phyla. Almost all of these phyla arose around the same relatively short era, during the Cambrian Explosion about 540 million years ago. The origin of such phyla must have required the origin of new genes at a rate many times greater than "one new gene per 100,000" years. The graph below shows the narrative of today's biologists about the origin of phyla during the past billion years, and how many arose during each part of that time. It's a narrative that is inconsistent with Darwinian gradualist explanations.
There follows more "coverup-the-complexity" nonsense from Lynch, such as these sentences below:
"For example, despite their added complexity for DNA replication and repair pathways, metazoans and land plants have substantially higher deleterious mutation rates than do prokaryotes. Despite their substantially more complex ribosomes and mechanisms for assembling them, eukaryotes do not have elevated rates or improved accuracies of translation, and if anything, catalytic rates and degrees of enzyme accuracy are reduced relative to those in prokaryotes (with simpler homomeric enzymes). Eukaryotes have diminished bioenergetic capacities (i.e., growth rates) relative to prokaryotes (21, 22), and this reduction is particularly pronounced in multicellular species (23)."
What is the motive of an evolutionary biologist such as Lynch in making these kind of "mammals are not so impressive" statements? The motive is a complexity coverup. Evolutionary biologists are profoundly embarrassed by the endless stupendous wonders of fine-tuned biological innovation and staggering heights of organization everywhere in the biosphere, which Darwinism does such a very crappy job of explaining. The greater the organization and functional complexity of an organism, the less credible it is to claim that the organism arose from unguided processes like those imagined by evolutionary biologists. So we see in the writing of evolutionary biologists and Darwinists a continual failure to properly describe the vast levels of organization, component interdependence, information richness and fine-tuned functional complexity of living organisms. And we may read evolutionary biologists writing a paragraph like the one quoted above, saying something that sounds like "mammals are not much better than microbes" nonsense.
A silly microbiologist
Lynch makes this claim: "The peculiar details of life’s structures and functions are legacies of historical contingencies, laid down prior to LUCA, which dictate all aspects of molecular assembly and breakdown." The LUCA he is referring to (Last Universal Common Ancestor) is something evolutionary biologists claim existed a billion years ago or earlier. So the structures and functions of human beings were "laid down prior to LUCA," "laid down" a billion years ago? That's baloney. You could write a very long book describing only human and mammalian functions and structures unlike anything that existed a billion years ago.
Instead of understanding any such thing as something that dictates "all aspects of molecular assembly and breakdown," today's scientists have no explanation for how the most complex molecules perform the way they do. Scientists cannot explain how it is that a protein molecule is able to form into the folded three-dimensional shape required for its function (a shape not specified in DNA or its genes). And scientists have no explanation for how proteins form into the protein complexes (teams of proteins) so often required for a protein to be useful. Below are some relevant quotes:
- "In real time how the chaperones fold the newly synthesized polypeptide sequences into a particular three-dimensional shape within a fraction of second is still a mystery for biologists as well as mathematicians." -- Arun Upadhyay, "Structure of proteins: Evolution with unsolved mysteries," 2019.
- "The problem of protein folding is one of the most important problems of molecular biology. A central problem (the so called Levinthal's paradox) is that the protein is first synthesized as a linear molecule that must reach its native conformation in a short time (on the order of seconds or less). The protein can only perform its functions in this (often single) conformation. The problem, however, is that the number of possible conformational states is exponentially large for a long protein molecule. Despite almost 30 years of attempts to resolve this paradox, a solution has not yet been found." -- Two scientists, "On a generalized Levinthal's paradox," 2018.
- "How proteins fold remains a central unsolved problem in biology. While the idea of a folding code embedded in the amino acid sequence was introduced more than 6 decades ago, this code remains undefined. While we now have powerful predictive tools to predict the final native structure of proteins, we still lack a predictive framework for how [amino acid] sequences dictate folding pathways....Almost seven decades of experimental and theoretical inquiry have not revealed a 'folding code' at the amino acid level, i.e., rules endowed with the generality and predictive power required to connect amino acid sequence to how the protein attains its structure....Machine learning made it possible to identify weak correlations to generate the structure most likely to correspond to a sequence. This tour-de-force effort has largely solved the problem of predicting protein structure from sequence...but with a key limitation: the algorithm that predicts the structure is a complex black box of pattern recognition that casts little light on the process of folding and that tells us nothing about why only some sequences fold, or how physics and evolution are coupled." -- Five scientists in the year 2025 (link).
- "The real challenge—that remains unanswered after more than 50 years of research in the structural biology field—is understanding the mechanisms that lead proteins to fold into their native state. The reason for these difficulties is that the central question of the protein folding problem remains unresolved: specifically, how a sequence of amino acids encodes its folding pathways." -- Scientist Jorge A. Vila, 2025 (link).
- "The majority of cellular proteins function as subunits in larger protein complexes. However, very little is known about how protein complexes form in vivo." Duncan and Mata, "Widespread Cotranslational Formation of Protein Complexes," 2011.
- "While the occurrence of multiprotein assemblies is ubiquitous, the understanding of pathways that dictate the formation of quaternary structure remains enigmatic." -- Two scientists (link).
- "A general theoretical framework to understand protein complex formation and usage is still lacking." -- Two scientists, 2019 (link).
- "Most proteins associate into multimeric complexes with specific architectures, which often have functional properties like cooperative ligand binding or allosteric regulation. No detailed knowledge is available about how any multimer and its functions arose during historical evolution." -- Ten scientists, 2020 (link).
- "Protein assemblies are at the basis of numerous biological machines by performing actions that none of the individual proteins would be able to do. There are thousands, perhaps millions of different types and states of proteins in a living organism, and the number of possible interactions between them is enormous...The strong synergy within the protein complex makes it irreducible to an incremental process. They are rather to be acknowledged as fine-tuned initial conditions of the constituting protein sequences. These structures are biological examples of nano-engineering that surpass anything human engineers have created. Such systems pose a serious challenge to a Darwinian account of evolution, since irreducibly complex systems have no direct series of selectable intermediates, and in addition, as we saw in Section 4.1, each module (protein) is of low probability by itself." -- Steinar Thorvaldsen and Ola Hössjerm, "Using statistical methods to model the fine-tuning of molecular machines and systems," Journal of Theoretical Biology
In his zeal to criticize "assembly theory," Lynch makes this damaging confession: "To sum up, all evidence suggests that expansions in genomic and molecular complexity, largely restricted to just a small number of lineages (one including us humans), are not responses to adaptive processes." What? So we don't get expansions in complexity as part of an adaption storyline? That contradicts endless thousands of previous claims by evolutionary biologists that evolution occurs as an adaption to the environment. As a scientific paper states, "The vast majority of biologists engaged in evolutionary studies interpret virtually every aspect of biodiversity in adaptive terms."
Lynch's next statement is pure hogwash: "Instead, the embellishments of cellular complexity that arise in certain lineages are unavoidable consequences of a reduction in the efficiency of selection in organisms experiencing high levels of random genetic drift." There is nothing "inevitable" about cells becoming more complex, and Darwinists don't have any credible explanation as to how cells could have increased so enormously in complexity.
But it seems that Lynch at least has a tiny bit of insight about his own hubris, because he says, "Some readers, probably including the authors of the above-mentioned papers, will argue that there is excessive hubris in the preceding paragraphs," referring to his own claims. Yes, Lynch has indeed been guilty of very bad hubris, groundless boasting, and a very silly attempt to coverup the stratospheric heights of dazzling innovation and information-rich organization in mammals and humans. Such coverups are like a child at the edge of the seashore, trying to push back the ocean by thrusting his palms against incoming waves.
Lynch's paper has some very bad hubris, particularly at the end when he makes the suggestion that evolutionary biologists may have little more left to do other than "stamp collecting." In an earlier paper he spoke as if the exact opposite was true, confessing that "the mechanisms by which complex cellular features evolve constitute one of the great unsolved problems of evolutionary biology." Two other biologists in 2006 made a similar confession in the quote below, making a confession that is the exact opposite of the boasts we so often hear from evolutionary biologists:
"Evolutionary biologists assert that variations must be sufficient, though they lack a general explanation for the origin of complex novel structures." -- Biologists Marc W. Kirschner and John C. Gerhart, "The Plausibility of Life: Resolving Darwin's Dilemma," 2006, page 4 (link).
