Research on centromere structure yields new insights.

Creationists, who, generally speaking, know little or nothing of biology and don't want to either because the risk of wondering it they could be wrong is far too great, are easily fooled by the frauds with a vested interest in keeping them simultaneously ignorant and imagining they have a deeper understanding than the millions of educated, working biomedical scientists who apply the Theory of Evolution every day of their working lives.

One thing they've been fooled into believing is that there is some sort of perfection in design inside a cell and that same designer is responsible for everything about living organisms.

But, in the last few years, under the onslaught of science, the frauds have needed to fall back from the demonstrably false notion of perfection of design in view if cancers, diseases and parasites, and now blame something for these obvious imperfections, which, by definition, could not be the products of a perfect designer god, do they have invented the biologically nonsensical notion of 'genetic entropy' and devolution caused by 'Sin' over which their omnipotent, omnibenevolent designer god is powerless.

And, again under the onslaught of science, the frauds have also conceded that evolution does indeed happen and happened at a massively accelerated rate to account for all the biodiversity produced by a small number of survivors of a genocidal flood just a few thousand years ago.

Evolution in Progress - How Two Isolated Populations in Papua New Guinea Have Diverged

Genetic adaptations have impacted the blood compositions of two populations from Papua New Guinea | Tartu Ülikool

An example of evolution if progress this week comes from a team of researchers from the universities of Tartu (Estonia), Toulouse (France), and Papua New Guinea. They have carried out an extensive analysis on blood samples from two populations in Papua New-Guinea who have remained isolated for the 50,000 years since Homo sapiens arrived on the Island.

One group occupies the highlands and the other group lives in the lowlands, making this a living laboratory to measure the effects of the different environments on the genomes of the two populations.

Different environments provide different drivers of evolutionary adaptation; for instance, the highlanders have adapted to a low oxygen partial pressure and comparatively few pathogens and an absence of mosquitoes; while the lowlands have both mosquitoes and a higher level of endemic pathogens. How each group has adapted to these different environments provides a text-book example of how the environment drives evolution and how isolation results in divergence.

The team's work is published, open access, in Nature Communications and is explained in a press release from Tartu University, Estonia:

Protracted development of stick tool use skills extends into adulthood in wild western chimpanzees | PLOS Biology

Chimpanzees are famous for making and using tools, especially sticks, for obtaining nutritional foods like grubs and termites, but using them takes time, just like a human child needs to develop motor skills to use tools such as pens and pencils with sufficient dexterity.

How they do so, and the stages they go through, was described recently in an open access paper in PLOS Biology by a team of animal behaviourists from l'Institut des Sciences Cognitives Marc Jeannerod (The Marc Jeannerod Institute of Cognitive Sciences), Lyon, France; the Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany, and the German Primate Center, Göttingen, Germany, who analyzed film of wild chimpanzees making and using stick tools in the Taï National Park, Côte d’Ivoire.

They concluded that, like human children, acquiring motor skills is not just a matter of practice, important though that it, but also depends on a protracted childhood during which they observe and copy adults with the necessary skills. In other words, young chimpanzees learn skill from their parents and elders, like a human apprentice.

The team's work was explained in information made available ahead of publication by PLOS, and published in SciTechDaily.com:

New sex-determining mechanism in African butterfly discovered - News - University of Liverpool

Once sexual reproduction had become established in multicellular organisms, there was selection pressure to determine the gender of a developing embryo, so the result was either genetically male or genetically female. In humans and other mammals, for example, this is achieved by the XY Chromosomes, which, unlike all the other chromosomes (autosomes) are not paired. A zygote with 2X (homozygous) becomes a female and a zygote with XY (heterozygous) becomes male. Because the zygote gets either one or the other of these chromosomes from each parent these are the only combinations possible, so we never see a YY zygote.

First effective treatment found for spitting cobra snakebite - Lancaster University

Snake venom is usually a potent cocktail of multiple different toxins, 'designed' to kill, mostly small vertebrate prey very quickly, so the snake can strike, then wait for the prey to become paralyzed or die before it can go very far.

The reason for this rich cocktail is an interesting piece of evolutionary biology that would embarrass any creationist with the courage to learn about it. It is the result of repeated arms races between the snake and its prey species. Not only that, but it involves new genetic information arising, by gene duplication and mutations - contrary to creationist dogma that such a thing is impossible.

As one prey species starts to evolve resistance there is selection pressure on the snake to change its venom to overcome the resistance or loose one source of food, but, there must be a balance between retaining one food species but loosing several others if the changed venom is less effective against them. Resistance usually arises when there is a change in receptor sites on cell surfaces, on which the venom acts so the active venom molecule doesn't bind to it.

Malevolent Design - How Creationism's Divine Malevolence Co-opted Red Squirrels To Spread Leprosy in Medieval England

Lepers having magic spells cast over them

Mycobacterium leprae

Ancient Mycobacterium leprae genome reveals medieval English red squirrels as animal leprosy host: Current Biology

Few places in Europe or elsewhere were more pious than Medieval England, but still creationism's pestilential malevolence continued to make people suffer with diseases such as bubonic plague, tuberculosis and the related leprosy. Even the extreme measures taken by believers to atone for imaginary transgressions that had brought about the Black Death had failed to assuage the putative designer god who was believed to be visiting this pestilence upon people.

The superstitious Bible-based belief in evil spirits and 'sin' as the cause of disease led to the social stigma that made the disease so feared and led to the isolation of sufferers in lepper colonies, and often reduced to begging to stay alive. Poor nutrition and poor sanitation led to a worsening of the condition and, although these counter-measures were visibly ineffective, such was the belief in the Bible that it was inconceivable that the disease could be caused by anything other than 'sin' and evil demons being permitted to enter the victim.

The modern equivalent of this victim-blaming superstition can be found in the modern creationist tactic of blaming 'Sin' and 'genetic entropy' for parasites, with demons being replaced by 'entropy' to make it sound sciencey. It is of course, Bible-based superstition without supporting evidence.

And now, if you believe that stuff, there is evidence that creationism's putative designer god designed M. leprae to also infect red squirrels so they would act as a repository to spread leprosy. Red squirrels were common in those days and were often captured in the wild for pets or pelts. Their skins, when used for clothing, would have carried M. leprae and infected anyone who wore them - a brilliant strategy, if you hate people and want them to be sick, suffer and die.

Two-spot spider mite, Tetranychus urticae

Plants utilise drought stress hormone to block snacking spider mites | Sainsbury Laboratory

To start at the beginning because that's always a good place to start, plants need to get water and nutrients up to their leaves, so their 'designer' gave them a vascular system but without a pump, so, to maintain the upward flow, they need to evaporate away (or transpire) the water that just arrived in their leaves. They do this through tiny pores (or stomata; singular=stoma) that are just about visible to the naked eye, and clearly visible under a hand lens or a microscope.

These stomata are guarded by guard cells, one on either side, which can swell to close the stoma or shrink to allow the stoma to open, as the need arises.

However, these stomata are an open invitation to sap-sucking arthropods such as mites and aphids, which are cleverly designed, reputedly by the same designer that designed the stomata, which can push their mouthparts into the stoma to get at the nutrient-rich watery contents of the leaf.

So, having designed these sap-suckers to exploit the transport system it designed for plants, creationism's putative designer clearly saw the sap-suckers it had designed as a problem to be solved.

How it added this Heath-Robinson layer of additional complexity to solve the problem the earlier layer of complexity had caused is the subject of a research paper by a collaboration of researchers from the Centre for Plant Biotechnology and Genomics (CBGP), Spain, and Sainsbury Laboratory, Cambridge University (SLCU), Cambridge, UK and a news release from Cambridge University:

Malevolent Designer News - How Creationism's Favourite Pathogen Is Designed to Cause UTIs

Escherichia coli,
The usual cause of urinary tract infection (UTI)

UTI's will affect 50% of women at some time in their lives

How E. coli get the power to cause urinary tract infections | Michigan Medicine

Despite their protestations that their god doesn't create pathogens - some other creative entity does that, apparently - they have been in love with Escherichia coli, or E. coli ever since their guru and Deception Insitute flunky, Michael J Behe, persuaded them that he had 'proved' their god exists and designs things because he couldn't work out how the E. coli flagellum could have evolved - so God did it!

There problem then, courtesy of Michael J Behe is that they have accepted that, if there was a designer involved in E. coli's design, it is the god that Michael J Behe 'proved' designed it, so their god designs pathogens, and even designs clever way to make them good at making us sick.

With that in mind, which creationist is going to argue against Michael J Behe's clever 'proof' that their god designs things so must exist, and insist that it isn't also behind the newly discovered way it manages to cause urinary tract infections (UTIs)?

The discovery that they can live, reproduce, and do their nasty thing in the otherwise near-sterile urinary tract, was made by researchers at the laboratory of Professor Harry Mobley in the University of Michigan Medical School.

Having been filtered by the kidneys, while urine contains some chemicals such as metabolites, it is about as sterile as it gets, with anything in it entering through the urethral meatus, in women, stupidly placed near the anus and inside the vulva where it can become infected during sexual intercourse by a penis cleverly designed with a foreskin to harbour pathogens under.

It has now been discovered that E. coli is also cleverly 'designed' to grab the nutrients it needs but can't manufacture itself by have a highly efficient transport system for taking them from its victims at a rate of thousands of molecules a second. One of the genes responsible for this, codes for an enzyme known as ATP-binding cassette (ABC).

Typical of creationism's 'intelligent' [sic] designer, if you believe in such a thing, is the Heath-Robinson workaround for the lack of genes for manufacturing these amino acids, where the parasite needs an energy-intensive ATP-based transport system, complete with multi-layered back-up systems to keep them working - the needless waste and needless complexity, so typical of evolved systems and the antithesis of intelligently designed systems. The researchers have published their findings, open access, in the journal PNAS and explained them in a University of Michigan news release:

Creationism in Crisis - The Origin of Modern Plants - 550 Million Years Before 'Creation Week'

Genomes of “star algae” shed light on origin of plants - Georg-August-Universität Göttingen

One of the prerequisites for irreducible complexity to emerge naturally without needing a designer is for the components to be there either as part of a pre-existing structure, or as the result of neutral mutations that have been retained because there is no selection pressure to get rid of them.

This was the situation the first land plants found themselves in about 550 million years ago when gene and genome duplication had created redundant genes that could mutate, diversify, and eventually provide the complex metabolic machinery to enable the marine algae to colonize the land and so beginning the greening of the planet. The result was the appearance of a sudden, one-off event that created the ancestor of land plants.

This is the conclusion of a large international team led by scientists from the Universities of Göttingen and Nebraska–Lincoln, who have published their findings, open access, in the journal Nature Genetics and explained it in a University of Göttingen news release:

Creationism in Crisis - Humans Had Domesticated Dogs At Least 10 Thousands Years Before 'Creation Week'

Ancient Mitogenomes Reveal the Maternal Genetic History of East Asian Dogs | Molecular Biology and Evolution | Oxford Academic

These days, no serious scientist sets out to prove the Bible is wrong; discovering truth does that anyway - for anyone who can join the dots and do the simple logic. For example, humans could not have domesticated dogs some 23,000 years ago in Siberia by domesticating the local variety of grey wolf, if the Universe is just 10,000 years old.

And yet a paper published recently in the journal Molecular Biology & Evolution shows that they did exactly that.

In the context of mitochondrial DNA, what are haplotypes? In the context of mitochondrial DNA (mtDNA), haplotypes refer to specific combinations of genetic variants or polymorphisms within the mitochondrial genome. Unlike nuclear DNA, which is inherited from both parents, mtDNA is passed down exclusively from the mother to all of her offspring. This maternal inheritance pattern makes mtDNA useful for studying ancestry, population genetics, and evolutionary history.

A haplotype represents a unique combination of nucleotide variations or mutations along the mtDNA sequence. By analyzing these haplotypes, researchers can track maternal lineages, study population migrations, and infer evolutionary relationships among different groups of individuals. Haplotypes are often used in studies of human populations, as well as in forensic genetics and medical research related to mitochondrial disorders.

Refuting the Bible was almost certainly not the intention of the authors, jointly led by Songmei Hu, of Joint International Research Laboratory of Environmental and Social Archaeology, Shandong University, Qingdao, China, and Xijun Ni and Qiaomei Fu, both of the Institute of Vertebrate Paleontology and Paleoanthropology, Center for Excellence in Life and Paleoenvironment, Chinese Academy of Sciences, Beijing, China, but the facts they discovered do just that. They had set out to resolve the question of where exactly dogs had been domesticated, based on an analysis of the mitochondrial DNA.

Mitochondrial DNA (mDNA) is inherited through the maternal line, so an analysis of the geographical and temporal distribution of the various haplotypes of mDNA and how they relate to one another should give an indication of where and when the ancestral haplotype lived.

How the team did this is explained in their paper:

Creationism in Crisis - A Newly-Discovered Mammal From Colorado - From 65 Million Years Before 'Creation Week'

OFFICIAL Denver Museum of Nature & Science : Colorado Discovery: Museum Scientists Identify New Species

Apart from some feathered dinosaurs that were destined to become birds, one of the few land vertebrates to survive the catastrophe that wiped out the remaining large dinosaurs and marine reptiles at the K-Pg boundary, was to go one to give rise to the entire mammalian order. They were small fury, probably nocturnal insectivores.

The fossil of one of these, from 65 million years ago (at about the time of the K-Pg mass extinction), has recently been discovered by Denver Museum of Nature scientists in Colorado, at Corral Bluffs, near Colorado Springs.

According to a press release from Denver Museum of Nature & Science: Denver Museum of Nature & Science researchers are excited to announce the fossil discovery of a species of a 65-million-year-old mammal that was collected in the Corral Bluffs area on the edge of Colorado Springs. The newly discovered species, named Militocodon lydae, is part of a group of animals that gave rise to all modern hoofed mammals, including deer, cows and pigs. The fossil skull and jaws of Militocodon lydae were uncovered from rocks dating back to just after the extinction of the dinosaurs. Roughly the size of a chinchilla, Militocodon lydae provides important clues about the explosive diversification of mammals in the wake of the dinosaur extinction.

Rocks from this interval of time have a notoriously poor fossil record and the discovery and description of a fossil mammal skull is an important step forward in documenting the earliest diversification of mammals after Earth’s last mass extinction.

How and when life rebounded in the aftermath of the extinction of the dinosaurs has been shrouded in mystery due to a poor fossil record. But thanks to an extraordinary discovery of remarkably complete fossils from Corral Bluffs, as well a recently awarded collaborative research grant from the National Science Foundation's Frontier Research in Earth Sciences, Museum scientists and collaborators are now able to paint a vivid picture of how and when life rebounded after Earth’s darkest hour. The study, published in April 2024, was led by Dr. Lucas Weaver, Kent State University, and Jordan Crowell, The Graduate Center, City University of New York. The researchers named the mammal Militocodon lydae in honor of two extraordinary contributors to the Corral Bluffs project: volunteer and retired Colorado Springs teacher Sharon Milito and Museum supporter and champion of Colorado Springs Lyda Hill.

Genomic Diversity in the Endosymbiotic Bacteria of Human Head Lice | Molecular Biology and Evolution | Oxford Academic

It's a basic principle of evolutionary biology that an obligate commensal, symbiotic or parasitic organism is evolutionary bound to the organism on which it is dependent, It follows then that the genomes of two or more organism in such a relationships will reflect the same major changes which drive evolution.

I have previously described how the evolutionary tree of the human head and body lice, Pediculus humanus, fits exactly on the evolutionary tree of Homo sapiens as we diverged from the common ancestor with chimpanzees. At the same time, our lice diverged from a common ancestor they share with the lice which are obligate parasites on chimpanzees, Pe. schaeffi.

Interestingly, our lice also reflect when we started wearing clothes having lost our body hair. This loss of body hair meant our lice became head lice which are closely related to the chimpanzee's body lice. When we started wearing clothes our lice diverged into two subspecies - head lice, Pe. h. capitis, and body lice, Pe. h. humanus.

And now, something even more interesting and confirmative of evolution, is the discovery that an obligate, symbiont bacteria on which the lice depends, shows exactly the same pattern of divergence, mapped onto the evolutionary tree of the lice.

The symbiotic bacterium, Candidatus Riesia pediculicola, in a typically Heath-Robinson solution to a problem which is a characteristic of mindless, unplanned evolution, and unlike anything an intelligent designer would design, is essential to the lice because they can't make essential B-vitamins and don't get them from the blood on which they exclusively feed.

And, incidentally, these bacteria have evolved by loss of genetic information - something that creationist frauds tell their dupes is impossible because "every loss of genes is invariably fatal" [sic].

This discovery is the subject of a recent open access paper in the journal Molecular Biology & Evolution:

New rock art discoveries in Eastern Sudan tell a tale of ancient cattle, the ‘green Sahara’ and climate catastrophe

From my own experience, the Sahara Dessert, at least the Tunisian part of it, is cold and wet!

At least that was what we experience a few years ago when we went there in early June, to avoid the heat of summer. That was a mistake, as Tunisia was experiencing one of the coldest Springs in living memory, when, at times, it felt like it was about to snow. We shivered at the Roman amphitheater at Al Jem where we were back on the coach within 20 minutes, asking for the heating to be turned on, and a trip to the Bardot Mosaic Museum in Tunis was spoilt by the rain.

But it was in the desert near Tozeur, dressed only in summer clothes, that we experienced a cold, wet Sahara, much as it may have been between 15,000 and 5,000 years ago when cattle herders were painting images of their cattle on the rocks at Atbai, east of Wado Halfa in Eastern Sudan. This period of Saharan 'greening' was when the West African subspecies of Rock dove (Columba livia lividor) managed to interbreed with a hybrid between C. rupestris and an Asian subspecies of C. livia, probably somewhere in the Sahara. And from that, probably all domestic and feral (town) pigeons are descended, as I described recently.

It was also where humans herded the cattle they had obtained from North African pastoralists, as described in the following article by Julien Cooper, Honorary Lecturer, Department of History and Archaeology, Macquarie University, Australia, reprinted here from The Conversation under a Creative Commons license. His article has been reformatted for stylistic consistency, but the text is unaltered:

Archaea can be picky parasites - NIOZ

The Bible is silent on the subject of microorganisms because they were unknown to the Bronze Age authors. But now we know better than them, we can see other ways in which they refute several basic creationist dogmas.

Firstly, there is the problem that creationists always struggle with when they don't avoid it altogether - that of parasites and how they fit into a world 'designed' by an omnibenevolent god who wishes to minimise the about of suffering in the world. More on this later…

Then the fact that archaea and bacteria could be different forms of life which arose independently showing that abiogenesis is not only possible but may have happened twice on Earth. And as they both have the same genetic 'code' this suggests that the 'code' was inevitable, not some special creation requiring a magician to produce it.

But that's a minority view; the consensus being that they have a common ancestor from which they diverged about 3.5 billion years ago.

Creationism in Crisis - How Neanderthals Were Burying Their Dead - 65,000 Years Before 'Creation Week'

Scientists have produced a remarkable reconstruction of what a Neanderthal woman would have looked like when she was alive. It is based on the flattened, shattered remains of a skull whose bones were so soft when excavated they had the consistency of "a well-dunked biscuit". Researchers first had to strengthen the fragments before reassembling them. Expert palaeoartists then created the 3D model.

BBC Studios

Shanidar Z: what did Neanderthals do with their dead?

Illustrated reconstruction of a Neanderthal man.

Hermann Schaaffhausen, 1888.

65,000 years before creationists believe the Universe existed, and before anatomically-modern humans had migrated out of Africa, a community of Neanderthals were living in a the Shanidar cave in what is now northern Iraq.

These Neanderthals also appear to have used the same cave in which to bury their dead, the skeletons of which are now being excavated to learn more about how these hominins lived.

And the picture emerges of a sophisticated people, very different from the brutal sub-human animals Victorian archaeologists depicted them as when Neanderthal remains were first discovered. Like many Creationists and US white supremacists today, Victorians were so wedded to the idea that modern (European) humans are the pinnacle of creation, that they could not conceive of the idea that there may once have been earlier humans who had anything approaching their level of sophistication.

One of the skeletons is of a man with a disabled arm who was probably deaf and had a head trauma that would have made him disabled and dependent, yet he had lived a long time, showing evidence of care and compassion.

Readers of Jean M. Auel's excellent series of imaginative, but painstakingly researched books about a Homo sapiens girl, Ayala, raised by Neanderthals will probably recognise Mog-ur, the Neanderthal tribal elder and shaman who befriended Ayala from that description...

The burials also suggest a sense of an after-life and care for the dead in that after-life. One skeleton is placed with its head pillowed on its hand presumably to make it comfortable.

One of the assembly of (female) skull fragments has been carefully removed from the rock matrix in which it was embedded and used to reconstruct her skull and then build a 3D reconstruction of how she would have appeared in life, for a BBC Netflix documentary on the excavation of the 35 individuals in the cave.

The work is the subject of an open access paper in the journal Antiquity and of a Cambridge University news article by Fred Lewsey:

Researchers parse oddity of distantly related bats in Solomon Islands that appear identical | KU News

There is something strange about the Solomon Islands, lying east of Papua New Guinea and northeast of Australia. The bats that inhabit the islands seem to have evolved in ways that are difficult to understand.

Before creationists get over-excited and think we've found an example of species that didn't evolve but were made by magic, the question is not whether they evolved, but how? The scientists are in no doubt that the process was an evolutionary one and show no signs of concluding that a supernatural entity was involved. The puzzle is that genetically distinct species on different islands, occupying the same niche, have evolved such a high degree of phenotypic convergence that they are almost indistinguishable, so were previously classified as the same species, although genetically they are not even close relatives. The question is what is it about the environment on these islands that has driven this high level of convergence.

Each of the islands in the archipelago has a population of bats, usually 3-5 species on each island, consisting of a small, medium and large species and on islands with four species, an extra-large. One island has five species so gets an extra small bat.

That all seemed fairly straightforward on the assumption that the five distinct species had each found a niche on each island, and they certainly looked identical when comparing the different sized bats on each island. However, that was before we had DNA sequencing techniques.

DNA analysis has shown that the large bats on different islands, although identical in appearance, are not closely related - they have converged on that appearance from different ancestral bats.

This was discovered by a research team of scientists from University of Melbourne, Australia, the University of Kansas, USA, Jame Cook University, Australia and others. Their work is published open access in the journal, Evolution (the National Journal of Organic Evolution). It is explained in a University of Kansas news release:

Creationism in Crisis - Wake UP And Smell The Coffee - It Evolved 600,000 Years Before 'Creation Week'

Newly sequenced genome reveals coffee’s prehistoric origin story — and its future under climate change - UBNow: News and views for UB faculty and staff - University at Buffalo

Creationists insist on seeing evolution as an event, not a process happening slowly over time, but there are a few rare examples where they are right - right by accident because few of them will have the courage to study evolutionary biology or even find out what it is and what processes cause it.

In the plant world, though not exclusively, new species arising by a single event such as hybridization between two related species which goes on to form a stable population that doesn't normally interbreed with either of the parent species, are fairly common. And one of them is the Arabica coffee plant, Coffea arabica, which is the result of a chance crossing between two diploid versions of Coffea canephora and Coffea eugenioides between 600,000 and 1,000,000 years ago to produce a state of allopolyploidia.

Because this represents such a narrow genetic bottle-neck with low genetic diversity, Arabic coffee is susceptible to infections and environmental hazards such as climate variability and soil conditions, so it needs carefully controlled conditions. It may well owe its long-term survival to the fact that it was cultivated by humans.

This was discovered by researchers at the University of Buffalo led by Victor Albert, Empire Innovation Professor in the Department of Biological Sciences, College of Arts and Sciences. Their paper is published, open access, in the journal Nature Genetics and their findings are explained in a University of Buffalo news release by Tom Dinki:

As an example of daft, Heath-Robinson design, the teeth of the North American sabre-toothed cat, Smilodon fatalis is a good as it gets. Obviously, having huge canine teeth with which to rip the throat out of large prey and so subdue it quickly, has some advantages, but the trouble is that the longer they are, the more likely they are to break, and broken teeth for a Smilodon could well have meant starvation and death. There needs to be a trade-off between ever-bigger teeth and death due to breakages.

And typical of creationism’s daft designer is the Heath-Robinson solution to a simple problem - you've guessed it, another layer of complexity. Instead of losing their 'milk teeth' like many mammals do as their head and mouth grows, Smilodon kept its milk teeth to act as a sort of splint for the adult Sabre tooth, reducing the lateral strain on the adult teeth until the adult was about 30 months old, by which time it had probably learned how to minimise lateral stress on its teeth.

This was discovered by Paleontologist Jack Tseng, associate professor of integrative biology at the University of California, Berkeley, who has published his findings in an open access paper in the journal The Anatomical Record. It is also explained in a University of California news release by Robert Sanders:

As I've remarked before, trying to debate with creationists is like boxing with a brain-dead opponent who lacks the cognitive ability to know when they're down and out. Their lumbering body keeps flailing around and like a defeated Donald Trump, insists that they’ve won, and are triumphing over all-comers in the ring.

Creationist frauds have been telling their willfully ignorant cult that they are winning the debate against science and science is about to convert to creationist superstition and abandon the materialist explanations. The science that has produced all of modern technology, including the computers and Internet that they use to inform the world that science is all wrong, and magic done by an unproven supernatural being is a better explanation for the observable facts, endearingly oblivious of the irony.

And yet not a single science paper has ever concluded any such thing and the small handful of pseudo-scientists that the creation cult employs to misinform the world never publish in peer-reviewed science journals. It's almost exactly like science just gazes bemusedly at the hopeless flailings of creationism, which has been on the canvas now for 50 years but still hasn't noticed. The trick has been to remain completely oblivious of real science by never reading anything that might make them wonder if being horizontal on the canvas is the best way of winning a boxing match.

Meanwhile real scientists do real science and science moves on.

An example of this was a paper published recently in Science which is the result on an AI assisted detailed analysis of the genomes of 1,154 strains of the ancient, single-cell yeast, Saccaromycotina, to discover how the different yeasts had evolved. Nowhere in the paper is there the slightest hint that the process that produced the different strains might be magic, not natural evolution. Instead, the research provides more understanding of how the evolutionary processes work.

The research by a team co-led by Professor of Bioinformatics Abigail Leavitt LaBella of the University of North Carolina at Charlotte, is explained in a University of North Carolina news release:

Creationism in Crisis - How Order Emerges From Chaos - Naturally

A 'murmuration' of starlings

It's a fundamental mantra of creationism that you'll see chanted over and over again as though it’s a proof that their god must exist, "You can't get order from chaos". It’s as fundamental, and as mindless, as the mantra, "You can't get life from non-life".

Both of them ignore the evidence and neither of them can be explained any more so than a parrot can explain its squawks.

And now a Tokyo University team has demonstrated that order can indeed emerge from chaos at different levels from the quantum to the macro level of flocks of birds, when there is a force acting between the particles to make it what they term an 'active matter'. They explain their findings in a highly technical, mathematical paper, the maths of which is quite incomprehensible to me, in the journal, Physical Review Research. The basic requirements for 'active matter' are that the particles (agents) are moving and that there is repulsion between them. In the case of a flock of birds, the repulsion is in the form of maintaining a distance between the individuals.

The researchers have explained their findings in a news release from Tokyo University:
