How Religion Drives Science and Why it Matters
You can see this video where I look at Jerry Coyne’s recent blog on determinism and the denial of free will, and a couple of scientific papers related to neurons and synapses.
Yesterday theoretical physicist Sabine Hossenfelder became the latest in a long line of smart people to make the absurd claim of determinism (see blog or video), and that therefore there is no such thing as free will. This silliness traces at least as far back as Laplace and is based on the idea that any system evolves from time point 1 to time point 2 according to the laws of nature. As Hossenfelder puts it:
These laws have the common property that if you have an initial condition at one moment in time, for example the exact details of the particles in your brain and all your brain’s inputs, then you can calculate what happens at any other moment in time from those initial conditions. This means in a nutshell that the whole story of the universe in every single detail was determined already at the big bang. We are just watching it play out.
The first problem with Hossenfelder’s sophism is that it is non empirical. We experience free will continually in our personal experience. Hossenfelder’s claim amounts to a denial of untold mountains of evidence. Hossenfelder’s predictable solution is anti-realism. The problem, according to determinists such as Hossenfelder, is that our experience is uniformly false. We may think we have free will, but that is nothing more than an illusion.
But why is that true? Hossenfelder makes the Humean appeal to the laws of nature. They show how systems evolve deterministically, so therefore the data from our personal experience must be false. Hossenfelder fails to see the unjustified leap she has made. She has declared the laws of nature to be authoritative without justification.
Hossenfelder has identified a conflict: our experience says one thing, and the laws of nature say the opposite. Something must give, and Hossenfelder unilaterally and without justification concludes that the laws of nature win out. The fallacy is reminiscent of Hume’s argument against miracles that John Earman demolished twenty years ago.
As if sensing a problem Hossenfelder attempts to justify her leap. She explains that “These deterministic laws of nature apply to you and your brain because you are made of particles,” and that “we know that brains are made of particles.” Furthermore, “the laws of nature that we know describe humans on the fundamental level.” But rather than saving the theory, Hossenfelder is merely digging deeper into the fallacy, as she simply begs the question. These are all non-empirical truth claims that are beholden to the assumption of determinism. She simply asserts these claims, but why should we believe any of them are true?
Yet Hossenfelder is supremely confident in her finding. Drop this free will nonsense, she warns, or “you will never understand how the universe really works.” This is the classic intellectual necessity argument, so common in the evolution literature. In this case it is determinism that is required for scientific progress and truth.
This brings us to the second problem with Hossenfelder’s determinism, which is her many truth claims. As she explains above, “the whole story of the universe in every single detail was determined already at the big bang.” But if that is true then Hossenfelder cannot know anything. Everything she has typed out was, well, pre-determined by some initial conditions and some blind natural laws.
Why should Hossenfelder think for a moment that anything that occurs to her has any correspondence to truth? Above she made the classic intellectual necessity argument but, in fact, it is precisely the opposite. Her determinism undercuts her many truth claims, and knowledge in general.
There would be no reason to think anything we ever generate has any particular truth value. For instance, I could decide to type 2+2=5. In fact, there I did it. But of course, Hossenfelder would say that sentence was all preordained. She also would say it is not true. So certainly preordained sentences are not necessarily true. In fact, for Hossenfelder our notions, thoughts, commitments, and conclusions are merely a consequence of the arrangement of particles in our heads. Why should we think they would be true, if there even is such a thing?
Hossenfelder’s conclusion, that “the whole story of the universe in every single detail was determined already at the big bang. We are just watching it play out” is fitting. For it is the ultimate in meaningless, trivialization of the profound. She is mired in the absurd. Hossenfelder is the best and the brightest—a cutting edge theoretical physicist. The wisest that the world has to offer and look where she has landed. As Paul informed the Corinthians in the introduction of his first letter to them, God made foolish the wisdom of this world.
Religion drives science, and it matters.
(1) More complex scaffolds may better support function, for example, by the introduction of a new active site at the interface between subunits. It has been estimated that roughly one sixth of oligomeric enzymes has an active site located at the inter-subunit interface.
(2) Oligomeric proteins can be allosterically regulated, introducing an additional level of control.
(3) There is a greater likelihood of an error-free transcript in a shorter protein sequence. A large protein composed of multiple, short, subunits, is more likely to be synthesized without errors than a single chain protein of comparable size.
(4) Where the monomer and oligomer differ in activity, additional regulatory flexibility may be achieved by regulating the conditions of oligomerization.
(5) Oligomeric proteins may be subjected to amplified evolutionary pressures, as deleterious mutations may be more pronounced and thus removed sooner from the gene pool. Conversely, the advantages of beneficial mutations may also be made evident sooner.
(6) Larger proteins are more resistant to degradation and denaturation. Indeed, an increase in oligomerization state is one of the protein stabilization strategies observed in thermophilic organisms.
In science and philosophy, a just-so story is an unverifiable narrative explanation for a cultural practice, a biological trait, or behavior of humans or other animals. The pejorative nature of the expression is an implicit criticism that reminds the hearer of the essentially fictional and unprovable nature of such an explanation. Such tales are common in folklore and mythology.
We hypothesize that, upon the onset of selective pressure from cold polar marine conditions, duplications of a 9-nt ancestral element in the midst of the four GCA-rich duplicates occurred.
The idea that the world operates according to its own laws and regularities remains controversial in the evolution debate today, as Intelligent Design proponents attack the consensus of science on Darwinian evolution and insist that God’s direct intervention in the history of life can be scientifically demonstrated.
the dominant biological paradigm - abiogenesis in a primordial soup. The latter idea was developed at a time when the earliest living cells were considered to be exceedingly simple structures that could subsequently evolve in a Darwinian way. These ideas should of course have been critically examined and rejected after the discovery of the exceedingly complex molecular structures involved in proteins and in DNA. But this did not happen. Modern ideas of abiogenesis in hydrothermal vents or elsewhere on the primitive Earth have developed into sophisticated conjectures with little or no evidential support.
independent abiogenesis on the cosmologically diminutive scale of oceans, lakes or hydrothermal vents remains a hypothesis with no empirical support
The conditions that would most likely to have prevailed near the impact-riddled Earth's surface 4.1–4.23 billion years ago were too hot even for simple organic molecules to survive let alone evolve into living complexity
The requirement now, on the basis of orthodox abiogenic thinking, is that an essentially instantaneous transformation of non-living organic matter to bacterial life occurs, an assumption we consider strains credibility of Earth-bound abiogenesis beyond the limit.
The transformation of an ensemble of appropriately chosen biological monomers (e.g. amino acids, nucleotides) into a primitive living cell capable of further evolution appears to require overcoming an information hurdle of superastronomical proportions, an event that could not have happened within the time frame of the Earth except, we believe, as a miracle. All laboratory experiments attempting to simulate such an event have so far led to dismal failure.
Before the extensive sequencing of DNA became available it would have been reasonable to speculate that random copying errors in a gene sequence could, over time, lead to the emergence of new traits, body plans and new physiologies that could explain the whole of evolution. However the data we have reviewed here challenge this point of view. It suggests that the Cambrian Explosion of multicellular life that occurred 0.54 billion years ago led to a sudden emergence of essentially all the genes that subsequently came to be rearranged into an exceedingly wide range of multi-celled life forms - Tardigrades, the Squid, Octopus, fruit flies, humans – to name but a few.
Its large brain and sophisticated nervous system, camera-like eyes, flexible bodies, instantaneous camouflage via the ability to switch colour and shape are just a few of the striking features that appear suddenly on the evolutionary scene. The transformative genes leading from the consensus ancestral Nautilus (e.g., Nautilus pompilius) to the common Cuttlefish (Sepia officinalis) to Squid (Loligo vulgaris) to the common Octopus (Octopus vulgaris) are not easily to be found in any pre-existing life form.
These data demonstrate extensive evolutionary conserved adenosine to inosine (A-to-I) mRNA editing sites in almost every single protein-coding gene in the behaviorally complex coleoid Cephalopods (Octopus in particular), but not in nautilus. This enormous qualitative difference in Cephalopod protein recoding A-to-I mRNA editing compared to nautilus and other invertebrate and vertebrate animals is striking. Thus in transcriptome-wide screens only 1–3% of Drosophila and human protein coding mRNAs harbour an A-to-I recoding site; and there only about 25 human mRNA messages which contain a conserved A-to-I recoding site across mammals. In Drosophila lineages there are about 65 conserved A-sites in protein coding genes and only a few identified in C. elegans which support the hypothesis that A-to-I RNA editing recoding is mostly either neutral, detrimental, or rarely adaptive. Yet in Squid and particularly Octopus it is the norm, with almost every protein coding gene having an evolutionary conserved A-to-I mRNA editing site isoform, resulting in a nonsynonymous amino acid change. This is a virtual qualitative jump in molecular genetic strategy in a supposed smooth and incremental evolutionary lineage - a type of sudden “great leap forward”. Unless all the new genes expressed in the squid/octopus lineages arose from simple mutations of existing genes in either the squid or in other organisms sharing the same habitat, there is surely no way by which this large qualitative transition in A-to-I mRNA editing can be explained by conventional neo-Darwinian processes, even if horizontal gene transfer is allowed.
Indeed there is much contemporary discussion, observations and critical analysis consistent with this position led by Corrado Spadafora, Yongsheng Liu, Denis Noble, John Mattick and others, that developments such as Lamarckian Inheritance processes (both direct DNA modifications and indirect, viz. epigenetic, transmissions) in evolutionary biology and adjacent fields now necessitate a complete revision of the standard neo-Darwinian theory of evolution or “New Synthesis " that emerged from the 1930s and 1940s.
Our results underpin the multifunctional nature of [centrobin] that plays different roles in different cell types in Drosophila, and they identify [centrobin] as an essential component for C-tubule assembly and flagellum development in Drosophila spermatogenesis.
Although the belief that an organ so perfect as the eye could have been formed by natural selection, is enough to stagger any one; yet in the case of any organ, if we know of a long series of gradations in complexity, each good for its possessor, then, under changing conditions of life, there is no logical impossibility in the acquirement of any conceivable degree of perfection through natural selection.
If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find out no such case.
Those who research the topic call this paradigm the “conflict mode” because it pits religion and science against each other, with little room for discussion. And researchers are starting to realize that it does little to illuminate the science of evolution for those who need it most.
The notion that there exists, and has always existed, a “warfare” or “conflict” between science and religion is so deeply ingrained in public thinking that it usually goes unquestioned. The idea was however largely the creation of two late nineteenth-century authors who confected it for personal and political purposes. Even though no serious historians of science acquiesce in it today, the myth remains powerful, and endlessly repeated, in wider circles
The reason for promoting both the specific lie about the sphericity of Earth and the general lie that religion and science are in natural and eternal conflict in Western society, is to defend Darwinism. The answer is really only slightly more complicated than that bald statement.
By the end of Biology 101, they can answer all the questions really well, but they don’t believe a word I say. If they don’t accept it as being real, then they’re not willing to make important decisions based on evolution — like whether or not to vaccinate their child or give them antibiotics.
our analyses indicate that mitochondria evolved from a proteobacterial lineage that branched off before the divergence of all sampled alphaproteobacteria.
After the Type I/II split, an ancestor to photosystem I fixed its quinone sites and then heterodimerized to bind PsaC as a new subunit, as responses to rising O2 after the appearance of the oxygen-evolving complex in an ancestor of photosystem II. These pivotal events thus gave rise to the diversity that we observe today.

Their [reaction centers’] first appearance and subsequent diversification has allowed photosynthesis to power the biosphere for over 3 billion years, in the process supporting the evolution of more complex life forms.
