Scientists Discover 165-Ma Jurassic Orthopterans with Leaf Mimicry, First for Co-preserved Insect-Plant Fossils----Chinese Academy of Sciences

When we think of leaf mimicry, we usually picture modern insects like stick insects or katydids blending seamlessly into their surroundings. But new fossil discoveries show that this evolutionary trick is far older than we might imagine. In fact, insects were already disguising themselves as leaves 165 million years ago, during the Jurassic, long before flowering plants even appeared.

Scientists at the Chinese Academy of Sciences have uncovered an astonishing fossil example of close mimicry between three species of orthopteran insects—a group that includes grasshoppers, crickets, and katydids — and the leaves of an extinct cycad-like seed-bearing plant, almost certainly the very plant on which they lived. These fossils come from the 165-million-year-old Daohugou Biota of Inner Mongolia, northeastern China.

Instances of defensive mimicry or camouflage are exactly what one would expect from evolution by natural selection. In fact, it would be more surprising if potential prey species hadn’t evolved some form of defence. To an intelligent design advocate, however, such examples are awkward to explain—unless one imagines a forgetful designer who repeatedly undermines his own work. Why design predators that rely on a given prey species for food, and then deliberately design prey that are difficult for those predators to find? An arms race against oneself is hardly the hallmark of an intelligent mind.

And yet, arms races are precisely what we observe throughout the natural world — whether in competition for resources, the struggle for the fittest mate, parasite–host dynamics, or, as in this case, the evolutionary contest between predator and prey.

Refuting Creationism - Evolutionary Divergence and Hybridization in Mediterranean Shearwaters

The Balearic shearwater (Puffinus mauretanicus, above) and the Mediterranean shearwater (Puffinus yelkouan, below) are two shearwater taxa that are genetically similar despite displaying morphological and migratory differences. The new study shows that these two taxa have undergone recurrent episodes of divergence and hybridization during the Pleistocene glacial and interglacial cycles, respectively. This serves as a key example of how hybridization can help preserve genetic diversity and evolutionary potential in threatened taxa.

Hybridization between species has been crucial to the survival of Europe’s most threatened seabird - Current events - University of Barcelona

Like the story of human evolution, that of two seabirds in the shearwater family living in the Mediterranean shows a history of divergence, followed by episodes of hybridization and genetic remixing. Normally, from a conservation perspective, hybridization is considered a problem because it can erode the distinctiveness of threatened species, diluting unique traits.

However, in the case of the Mediterranean shearwater (Puffinus yelkouan) and the critically endangered Balearic shearwater (Puffinus mauretanicus), hybridization has had the opposite effect. By introducing genetic diversity into the Balearic shearwater, it may have improved the species’ chances of survival, potentially making the difference between persistence and extinction.

This evolutionary story sits uneasily with the worldview of Bible-literalist creationists. The very fact of species interbreeding undermines the notion of fixed, separately created “kinds.” It also contradicts the idea that a few thousand years ago all life was destroyed in a global flood, followed by a period of hyper-rapid diversification into the species we see today—a process which, according to creationist claims, left no trace in the fossil record. If hybridization had occurred during that supposed burst of post-Flood diversification, it would simply have blurred the lines between “kinds,” creating variation within species rather than producing the multitude of distinct species we observe today. In other words, the evidence shows that life’s history is one of gradual divergence, occasional genetic exchange, and long-term adaptation—not sudden, discrete acts of “special creation.”

A recent study led by Professors Julio Rozas, Marta Riutort, and Jacob González-Solís of the Faculty of Biology and the Biodiversity Research Institute of the University of Barcelona (IRBio), together with Joan Ferrer Obiol of the University of Milan, has revealed how this evolutionary pattern unfolded. Using genomic analysis, they showed that the two shearwater species have gone through repeated cycles of divergence and hybridization, largely driven by the glacial–interglacial rhythms of the Pleistocene. Each cycle of isolation and secondary contact left genetic signatures that are still visible today.

The researchers found a clear gradient of genetic differentiation across the Mediterranean, with hybrid populations becoming increasingly common as one moves westwards, culminating in the Balearic Islands of Ibiza and Formentera. Intriguingly, the shearwater population on Menorca is genetically closer to P. yelkouan than to P. mauretanicus, reflecting its history of admixture. Far from being detrimental, this interbreeding has enriched the Balearic shearwater’s genome, reducing inbreeding risks and helping to preserve adaptive traits that may otherwise have been lost.

Malevolent Design - How The Poxvirus is 'Intelligently Designed' To Rapidly Multiply

A Survival Kit for Smallpox Viruses - Universität Würzburg

Researchers at Julius Maximilian University of Würzburg (JMU) have discovered that poxviruses have developed a unique strategy to multiply rapidly after infecting a host cell. They achieve this by assembling a large protein complex with the help of a transfer RNA (tRNA) molecule. Remarkably, this is the first known example of a ‘chaperone’ function being carried out by a tRNA rather than a protein. Each component of the assembly plays a specific role in the production of new poxviruses. Crucially, the complex only functions when all parts are correctly assembled, and the tRNA is indispensable for this construction.

In other words, the tRNA provides the essential element of the complex, which some might describe—using the Discovery Institute’s own terms—as containing “complex specified information” and forming an “irreducibly complex” system essential to the virus’s success.

By that same logic, it follows that the viruses responsible for smallpox and mpox (monkeypox) must have been intelligently designed. This leaves creationists with an unenviable dilemma:

• Accept the Discovery Institute’s definitions and admit their designer created deadly viruses — theologically awkward.
• Claim another intelligence designs life, beyond their god’s control — even more awkward.
• Abandon the Institute’s “evidence” for intelligent design — politically awkward.

The Evolution of Poxviruses

• Ancient lineage: Poxviruses belong to the family Poxviridae, a large group of double-stranded DNA viruses. Genetic evidence suggests they have been co-evolving with vertebrates (and possibly invertebrates) for hundreds of millions of years.
• Large, stable genomes: Unlike RNA viruses, which mutate rapidly, poxviruses have relatively stable genomes (~130–300 kilobases). However, they evolve through gene gain, loss, and duplication rather than high mutation rates.
• Host adaptation: Different poxvirus lineages have specialised for distinct hosts—mammals, birds, reptiles, and insects. For example, Variola virus (smallpox) evolved to infect only humans, while Vaccinia has a broader host range.
• Mosaic evolution: Poxvirus genomes show evidence of “mosaic” evolution, where genes are picked up from hosts or other viruses. This explains their arsenal of immune-modulating genes, which help them evade host defences.
• Smallpox origins: Genetic studies suggest that Variola virus diverged from an ancestral rodent poxvirus thousands of years ago. The earliest written descriptions of smallpox-like disease appear in ancient India, China, and Egypt (at least 3,000 years ago).
• Ongoing evolution: Modern relatives, such as monkeypox (mpox), cowpox, and camelpox, continue to evolve, sometimes crossing species barriers. This zoonotic potential makes them a persistent public health concern.

The discovery of the essential role of this viral tRNA in the success of poxviruses is reported in an open-access paper in Nature Structural & Molecular Biology. It is also summarised in a news release from Universität Würzburg.

A Survival Kit for Smallpox Viruses

---

A study from Würzburg reveals: pox viruses have developed a unique strategy to rapidly multiply after infecting a host cell. The findings uncover a previously unknown role for a well-known molecule and may serve as a starting point for the development of new antiviral agents.

---

In the English society of former times a “chaperone”, traditionally an older woman, was assigned to accompany a young unmarried woman to ensure her proper behavior, especially during interactions with men, in line with the social norms of the time. In biochemistry, "chaperones" also play a protective role. One of their main functions is to assist newly synthesized proteins in folding correctly and to prevent misfolded protein chains from clumping. Other chaperones, known as “assembly chaperones,” help to bring together various building blocks in the densely packed cellular environment and arrange them into large protein complexes. Without these crucial functions, life as we know it would not be possible.

Now, scientists at the University of Würzburg have discovered a previously unknown type of assembly chaperone during their analysis of poxviruses, and they have decoded its function in full detail. The unique aspect: this is the first known chaperone that is not formed by a protein but by a nucleic acid — specifically RNA, even more precisely, a tRNA or "transfer RNA."

Published in Nature Structural and Molecular Biology

This study was led by a research team under Professor Utz Fischer, Chair of Biochemistry at the Julius Maximilian University of Würzburg (JMU) and an associate member of the Helmholtz Institute for RNA-based Infection Research (HIRI). Additional collaborators included Professors Claudia Höbartner and Bettina Warscheid from JMU’s Faculty of Chemistry and Pharmacy, as well as researchers from Innsbruck, Hanover, and Chicago. The team has now published the results of their work in the journal Nature Structural and Molecular Biology. These findings could serve as a basis for the development of new drugs against poxviruses.

A Key Role in Gene Expression

In our study, we focused on a large protein complex: the so-called complete vRNAP, an RNA polymerase found in vaccinia, the prototypical poxvirus.

This enzyme consists of 15 proteins and one RNA molecule and plays a crucial role in gene expression — the process by which genetic information is translated into proteins.

Each component of the complex has a specific task in this process. One factor helps the polymerase attach to the start sites (promoters) of viral genes, another enables it to detach from the promoters, and a third modifies the newly formed messenger RNA.

All in all, this protein complex acts like an ‘all-in-one unit.'

What intrigued her most was the question of how so many proteins could be assembled into such a highly ordered structure. In other words: who is the architect of this complex?

To answer that, we combined biochemical and structural biology approaches to identify each individual step.

Dr. Julia Bartuli.

Discovery of a Surprising Player

The team discovered that the complex is built by an assembly chaperone — a molecule that changes its structure while carrying out a specific task and then returns to its original form. To their surprise, they found that this chaperone is not made of protein but of RNA.

Typically, RNA has no role in this kind of process. Yet here a tRNA sits centrally between the polymerase and the associated factors, ensuring their cohesion and readiness to initiate gene expression.

Dr. Clemens Grimm, co-corresponding author
Department of Biochemistry
Theodor Boveri-Institute
University of Würzburg, Würzburg, Germany.

[Dr Grimm] was responsible for the structural analysis in the study. Further experiments on the role of tRNA revealed that without it, the other components of the complex have no affinity for each other and would not assemble correctly on their own. Only with the help of the tRNA do they come together in a specific sequence — during which the tRNA itself changes structure. This locks the system into place and stabilizes it.

The remaining question was: what is the purpose of this complex? To understand this, one needs in-depth knowledge of smallpox viruses:

Smallpox viruses are DNA viruses that never enter the nucleus of the infected cell. Instead, their replication occurs entirely in the cytoplasm. This means the virus must bring along everything it needs to initiate transcription and thus its own replication.

Professor Utz Fischer.

And that is precisely the role of complete vRNAP.

Kickstarting Transcription

The complex is formed in a late stage of the infection and then integrated into a new virus particle. It functions there as a “kickstarter for transcription.” All essential components are bundled together to ensure a smooth start during the initial phase of infection. So essentially, this complex serves as a kind of “survival kit” that enables poxviruses to rapidly multiply within infected cells.

Although this is basic research on the vaccinia virus, the findings could have important implications given current developments in Africa. For the past three years, Mpox viruses have been emerging in several countries, causing localized outbreaks. Their relation to vaccinia is made clearer by their former name: until recently, they were known as "monkeypox."

Dangerous Mutations in Mpox Viruses

Since Mpox viruses have so far only spread through close physical contact, the number of infections has remained relatively low — nothing like SARS-CoV-2, the virus responsible for the COVID-19 pandemic. However, this appears to be changing:

In Africa, we’re observing that the virus is mutating and finding new transmission routes.

Professor Utz Fischer.

For centuries, classical smallpox — caused by the poxvirus variola— ranked among the most dangerous diseases. Fischer even calls it the ultimate “killer.” The development of vaccinia-based vaccines and worldwide vaccination campaigns eventually led to its eradication; the world has been officially smallpox-free since 1980. Since then, however, vaccinations have ceased — meaning a mutated Mpox virus would encounter generations with no immunity. In that case, it might become necessary to rapidly develop drugs to combat the disease — especially since the mortality rate is relatively high among children and pregnant women.

“In the search for new therapeutics, our findings could be very helpful,” agree Utz Fischer and Clemens Grimm. The complex provides numerous docking sites for potential inhibitors and is well-suited for drug screening — the systematic search for new medicinal compounds.

Abstract
Transfer RNAs (tRNAs) are widely recognized for their role in translation. Here, we describe a previously unidentified function of tRNA as an assembly chaperone. During poxviral infection, tRNA^Gln/Arg lacking the anticodon mcm5s2U34 modification is specifically sequestered from the cellular tRNA pool to promote formation of a multisubunit poxviral RNA polymerase complex (vRNAP). Cryo-electron microscopy analysis of assembly intermediates illustrates how tRNA^Gln/Arg orchestrates the recruitment of transcription and mRNA processing factors to vRNAP where it controls the transition to the preinitiation complex. This is achieved by an induced fit mechanism that internalizes anticodon base G36 into the anticodon stem, creating a noncanonical tRNA structure and selecting a defined tRNA modification pattern. The role of tRNA as an assembly chaperone extends to the pathogenic Mpox virus, which features a similar vRNAP.

Main
Transfer RNAs (tRNAs) are best known for their role in decoding mRNA codons and translating them into proteins¹. However, certain tRNAs are also involved in a variety of noncanonical functions including nutrient sensing², splicing³, transcription⁴, apoptosis⁵ and scaffolding⁶, as reviewed by Su et al.⁷. In these contexts, tRNAs or their fragments can act as antisense decoys, protein modulators, primers or sensors. Recently, human tRNA^Gln and, to a lesser extent, tRNA^Arg have been identified in a cellular context that is not consistent with any of the established functions of tRNAs. Specifically, these tRNAs (termed tRNA^Gln/Arg throughout this manuscript) were found to be a stoichiometric component of a macromolecular RNA polymerase complex, known as complete vRNAP, which forms in cells upon infection with the prototypic poxvirus vaccinia⁸.This virus belongs to the diverse group of nucleocytoplasmic large DNA viruses, comprising double-stranded DNA viruses that express their genome within the cytoplasm of their host using their own gene expression machinery^9,10. The megadalton complete vRNAP unit integrates the poxviral core RNA polymerase (core vRNAP), composed of eight Rpo subunits, with early transcription factors Rap94, VETF-s, VETF-l, NPH-I and E11, the capping enzyme dimer D1/D12 and host tRNA^Gln/Arg.

We showed previously that recruited tRNA^Gln/Arg is uncharged and tethers associated factors to vRNAP through interactions with Rap94, NPH-I and VETF-l (ref. ⁸). Consistent with its biochemical composition, complete vRNAP acts as an autonomous early transcription unit capable of generating m⁷G-capped transcripts^8,11. Notably, tRNA^Gln/Arg, although part of this complex, is not directly involved in transcription and is absent from all DNA-bound transcription complexes identified to date. We, therefore, hypothesized that these tRNAs do not function as transcription factors but rather as chaperones that control the association of vRNAP with adjunct factors required for early transcription. Here, we combined a biochemical reconstitution system with structural analysis by cryo-electron microscopy (cryo-EM) to investigate the assembly pathway of complete vRNAP. Our study uncovers an unknown function of a specific tRNA as an assembly chaperone and reveals a unique induced fit mechanism that involves structural rearrangement of the tRNA, enabling complex formation.

Examples such as this highlight just how awkward concepts like “irreducible complexity” and “complex specified information” become when applied consistently. If creationists really believed their own definitions, they would be forced to concede that parasites and deadly pathogens are the work of an intelligent designer — one who seems far more interested in inventing ways to kill, cripple, and exploit life than in benevolence. Unsurprisingly, they prefer to ignore such cases.

The reason is clear enough: the creationist framework cannot accommodate the reality that complexity is just as often harnessed for destruction as for life. To admit this would raise unbearable theological questions about their supposed designer’s motives and character.

By contrast, the theory of evolution requires no such contortions. Natural selection explains both the sophistication and the cruelty of parasites and pathogens as the outcome of blind, undirected processes. Complexity arises because it works — not because it was willed. Evolution offers the simpler, more coherent explanation, if only creationists were willing to face it honestly.

Fossil fish sheds new light on extra teeth evolution to devour prey - University of Birmingham

Palaeontologists led by Professor Sam Giles of Birmingham University, UK, have discovered the earliest known example of a ray-finned fish, Platysomus parvulus, with extra teeth deep inside its mouth. It lived around 310 million years before creationists believe Earth was created. Aside from that insurmountable problem for creationist mythology, there are other difficulties for their childish beliefs:

Creationists insist that death only “entered the world” as a result of “Eve’s sin”. Before that supposed event, some 6,000–10,000 years ago, nothing ever died. Taken literally, this would mean that every mouthful of food remained alive throughout the entire digestive process, only to be excreted still living at the other end. Alternatively, humans and animals didn’t eat at all, somehow running on an unidentified, miracle source of energy. Either way, the claim collapses into absurdity.

An additional disappointment for creationists is that this team of evolutionary biologists show no hint of the widely predicted (in creationists circles) abandonment of the Theory of Evolution in favour of creationism, that two generations of creationists have been told will happen, like the second coming of Jesus, "Any day now, real soon. You'll see!".

From an evolutionary biology perspective, this fossil sheds light on the diversification of ray-finned fish following the End-Devonian mass extinction and represents a transitional stage in the evolution of tongue-biters from simple jawed fish. It also shows that advanced forms evolved relatively quickly in ecosystems dominated by predator-prey relationships.

Creationism Refuted - Fossil Record Of Fatal Pathogens In Brazil - 80 Million Years Before Creation Week

Deadly bone disease wiped out long-necked dinosaurs in what is now the interior of the state of São Paulo, Brazil

According to creationist dogma — though not explicitly stated in the Bible but added later to patch over awkward evidence — death did not enter the world until Eve’s sin somehow allowed it to. Along with death, so the story goes, came parasites, pathogens, and anything else creationists find inconvenient. And, of course, all of this supposedly happened just 6,000–10,000 years ago.

The problems with that are two-fold:

• Firstly, there is the question of what Adam and Eve, and the animals allegedly created for their use, ate. Did the plants they consumed remain alive as they passed through the digestive system, nutrients extracted but the plant cells excreted still living? Or did none of them eat anything at all? Obviously, the myth’s authors didn’t understand that plants are just as alive as animals.
• Secondly, the entire narrative collides with the fossil record, which shows long-dead animals preserved in strata dated to tens or even hundreds of millions of years before the mythical ‘Creation Week’—during the 99.9975% of Earth’s history that creationism simply erases. Those animals had metabolisms dependent on consuming living or dead tissues, and their fossils often show evidence not only of death, but of predation, parasitism, and disease. Many evolved armour plating, spines, and other defences that make sense only in the presence of predators and pathogens.

And here’s a paradox creationists often tie themselves in knots over: did God design humans with an immune system, or was it a post-Fall upgrade? If it was there from the start, then God was already planning for parasites and pathogens—hardly the “perfect” world creationists claim. If it was added later, then God wasn’t omniscient, as he failed to foresee a future need. Either way, the story collapses under its own contradictions.

It is therefore no surprise that researchers from the Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) and the Regional University of Cariri (URCA) in Crato, Ceará, Brazil, have found evidence of dinosaurs being infected—and killed—by osteomyelitis around 80 million years before ‘Creation Week’. Fossils of sauropod dinosaurs show clear signs of active osteomyelitis, with no signs of healing, indicating that the disease proved fatal.

A planetary accretion disk forming around a star.

Unusual carbon dioxide-rich disk detected around young star challenges planet formation models - Stockholm University

This, the last in this series - at least for a while - is on the discovery made by the James Webb Space Telescope (JWST) of a disk rich in carbon dioxide around a young star. Apart from again highlighting the yawning gap between the Bible's child-like description of the universe and the real thing, it also showcases how, contrary to creationist conspiracy theorists’ claims that scientists are not allowed to publish anything which challenges “scientific orthodoxy,” a discovery that challenges the current consensus is openly flagged to the scientific community in peer-reviewed publications.

The problem this raises for cosmology is that, in the standard model of planetary formation, icy grains from the colder outer regions of a disk drift inward. As they cross the so-called snow lines, the ice sublimates into gas: first carbon dioxide, then closer in, water vapour. Because both species are expected to follow this process, astronomers normally expect water vapour to be at least as abundant as, if not more abundant than, carbon dioxide in the warmer inner regions. Yet in the disk surrounding a young star in the star-forming region NGC 6357, JWST found the reverse of what models predict — little or no water, but a striking abundance of carbon dioxide.

Intriguingly, the observation may also help explain another puzzle: the unusual isotopic fingerprint found in meteorites and comets. The imbalance of gases could be linked to intense radiation altering chemical pathways in the disk.

For Bible literalists, however, such details have no bearing on their imagined universe of a small, flat Earth with a dome overhead and fixed, immovable stars. There is no recognition in their text of star formation, accretion disks, or the vastness and dynamism of a changing cosmos. The Bible’s universe doesn’t even contain planetary systems.

Early galaxies — or something else? Mizzou scientists uncover mysterious objects in the universe

In this fourth article in the series contrasting the real universe with the one described in the Bible, I look at the announcement that two cosmologists from the University of Missouri have discovered about 300 objects that are brighter than they should be if they are what researchers think they are – some of the first galaxies in the early universe. If that's what they turn out to be, it will require a reassessment of what cosmologists thought they knew about the formation of galaxies.

This highlights a frequently repeated contradiction in creationist claims: on the one hand, they insist scientists are only allowed to publish papers that conform to existing consensus, so "creationist science" never gets published; on the other hand, they complain that scientists keep changing their minds and rewriting the science books, unlike the Bible which never changes. They claim this means science is unreliable and not to be trusted. Obviously, both can't be right, but that doesn't stop creationists from claiming both simultaneously.

The other problem this paper highlights is the sheer scale of the universe and the timeline involved, which make the Bible's account look laughably naïve, even childish in its simplicity.

These mystery objects, discovered by the James Webb Space Telescope, are in the order of 13–14 billion light-years in look-back time, meaning we are seeing the light that left them when the universe was only a few hundred million years old. Because the universe has been expanding ever since, their actual present-day distance is much greater — probably 25–30 billion light-years away.

This doesn’t contradict the 13.8-billion-year age of the universe: the light has only been travelling for 13 billion years, but in that time the fabric of space itself has stretched. It’s a bit like two ants on a rubber band: one ant flashes a signal when it is 13 cm away, but by the time the other ant sees it, the band has stretched so much that they are now 30 cm apart. The signal only travelled 13 cm, but the current separation is larger because of the stretching. To suggest, as creationists must, that the well-established methods of cosmological distance measurement are so wrong that they confuse a universe a few thousand years old with one tens of billions of light-years across, is to cling to absurdity.

In fact, this paper shows science at its best. The researchers are effectively saying to their colleagues: “Look, we may have found a fundamental problem that could mean we were wrong all along. Let’s investigate further and be prepared to change our minds if the evidence demands it.” Now imagine a creationist announcing that they had discovered a contradiction in the Bible that forced them to question its divine authorship, or a Discovery Institute fellow admitting to evidence that could only be explained by Darwinian evolution. Such an admission would simply never happen — and certainly never be published in a creationist outlet.

Science is reasonable uncertainty; religion is unreasonable certainty.

In this, the third entry in the series, we turn to an extraordinary image of a nebula popularly known as “The Hand of God.” Like the famous Horsehead Nebula, its nickname arises simply because it happens to resemble something faintly recognisable—in this case, the outline of a human hand. Some creationists may take comfort in that name, imagining it to mean that scientists literally see the hand of God at work in the creation of the universe.

Few things could be further from the truth. The more we learn, the clearer it becomes that the universe is not the product of spells cast by a supernatural magician, as described in the Bible, but the result of natural forces acting on a scale so vast the authors of Genesis could never have conceived it.

Without modern science—and without the stunning images produced by instruments such as the James Webb Space Telescope and the Chandra X-Ray Observatory which created this composite — we too would struggle to imagine the universe as it really is. Expecting Bronze Age pastoralists to have described it accurately would be like asking a five-year-old today to look up at the night sky and provide a scientific account of the cosmos.

What we see here is just a tiny fraction of the heavens — the area covered by a single grain of rice held at arm’s length — yet, by combining electromagnetic images at different wavelengths, scientists have rendered the nebula visible in all its grandeur.

Using exoplanets to study dark matter | UCR News | UC Riverside

The second of five blog posts that comprehensively refute any lingering notion that Genesis is the inerrant word of a creator god, rather than the best guesses of primitive Bronze Age pastoralists, who imagined Earth as a small, flat plane beneath a solid dome. This time, the focus is on news from a University of California Riverside (UCR) team, who are using the more than 5,000 exoplanets discovered to date to investigate the mysterious phenomenon of dark matter.

Dark matter poses a challenge for science—not because its existence is in doubt, but because its nature and relationship to the standard model of particle physics remain unknown. We know it exists because it exerts gravitational effects on galaxies and other cosmic structures, yet it does not appear to interact with ordinary matter in any detectable way. What we can infer, however, is that dark matter makes up a substantial fraction of the universe’s total mass.

For science, this is a puzzle to be investigated head-on. For creationists, however, both the confirmed existence of thousands of exoplanets and the reality of dark matter are insurmountable contradictions to their Bible-based cosmology. The Genesis account insists on a tiny, flat Earth, immovably fixed at the centre, covered with a dome, with waters above and below — a description so far removed from reality that it cannot honestly be excused as metaphor, allegory, or poetic licence. It is simply wrong.

Unlike science, which welcomes such problems as opportunities to investigate and refine our understanding, religion turns a blind eye and ploughs on, muttering about “mysterious ways,” “beyond human comprehension,” or simply, “God did it!” — all while smugly pretending the issue has been solved “by faith.”

Creationists normally assume that scientists are all out to destroy their faith because they hate God and/or worship Satan, so to add to that paranoid delusion, this is the first of five blog posts about very recent discoveries in the fields of Astronomy and cosmology that illustrate the glaring contrast between the real universe and the universe described in Genesis. The Bible describes a small, flat planet fixed and immobile at the centre, covered by a solid dome, with water above and below and stars, sun and moon fixed to the dome as lamps and tiny lights that can shake lose and fall to Earth during earthquakes; the whole thing created just 6,000 - 10,000 years ago from nothing.

The first of these papers is by an international team of astronomers, led by The University of Texas at Austin’s Cosmic Frontier Center who have discovered the most distant black hole ever confirmed. It is in the galaxy CAPERS-LRD-z9 which formed 500 million years after the Big Bang. That places it 13.3 billion years into the past, when our universe was just 3% of its current age. A time line and distance completely off the Bible's scale.

USF, FAU researchers solve 1,500-year-old mystery: The bacterium behind the first pandemic

The notion of intelligent design — the current flagship of creationism’s attempt to replace scientific realism with magical superstitions and Bible literalism dressed up as “alternative science” — contains a blatant paradox its advocates must ignore: the very same “logic” used to argue that the God of the Bible created living organisms can just as easily be used to argue that any such designer is a malevolent sadist who deliberately increases suffering in the world while ignoring countless ways to reduce it.

The theological problems this raises are never discussed in polite creationist circles, except for the lazy fallback of blaming everything on “The Fall.” But this move exposes intelligent design for what it really is — Bible-literalist religion in disguise. And that sits awkwardly against over half a century of insistence by the Discovery Institute that ID is not a religious idea, but rather a scientific one that should be taught in American public schools at taxpayer expense — a direct violation of the Establishment Clause and the U.S. Supreme Court’s ruling in Edwards v. Aguillard (1987).

The paradox lies in the fact that the very same so-called evidence — Michael J. Behe’s “irreducible complexity” and William A. Dembski’s “complex specified genetic information” — can be found in the genomes, structures, and processes of parasites and pathogens, making them devastatingly effective at exploiting and destroying their hosts. In fact, Behe himself has, probably without realising it, used precisely such examples. The bacterial flagellum he highlights enables E. coli to move efficiently through our gut, causing sometimes fatal food poisoning. And his example of resistance to anti-malarial drugs in Plasmodium parasites illustrate how evolution equips them to continue killing hundreds of thousands of children every year while condemning millions more to cycles of malarial fever.

Now, new research has highlighted another gruesome example. The bacterium Yersinia pestis — responsible for multiple waves of plague throughout the Middle Ages — has been shown to have evolved into its highly lethal form only in relatively recent human history. Beginning with the “Plague of Justinian” about 1,500 years ago, Y. pestis unleashed pandemics that killed between 30% and 50% of Europe’s population.

An interdisciplinary team at the University of South Florida (USF) and Florida Atlantic University (FAU), with collaborators in India and Australia, has now confirmed genomically that the Justinian plague was indeed caused by Y. pestis, as long assumed. Analysing DNA from plague victims buried in a mass grave at the ancient city of Jerash, Jordan — the epicentre of that pandemic — one group identified the culprit, while another team traced the bacterium’s evolutionary changes that made it one of history’s most notorious killers.

Creationism Refuted - Filling The Gaps That Ignorant Creationists Never Knew Existed

There was a gaping hole in our knowledge of evolution which, had creationists been aware of it, we would never have heard the end of. They would have claimed that their gap-shaped god fitted it perfectly, like a puddle in its hollow. Of course, it was no secret. Biologists—especially those studying the evolution of lizards—knew about it well enough. No one was hiding it from creationists. Their blissful ignorance was simply the result of their fear of engaging with real biology.

We knew that today’s large-bodied lizards must share common ancestors, but the gap lay in the fossil evidence to support that view—what creationists dismissively call “conjecture” or claims made without evidence. Yet the Theory of Evolution always predicted that such ancestral and transitional forms must have existed.

Creationists, however, have missed that particular boat because the gap has now been filled. The prediction of evolutionary theory has, once again, been vindicated.

The gap-filling discovery was made by Dr Hank Woolley of the Dinosaur Institute while examining a jar of bones at the Natural History Museum of Utah, simply labelled “lizard bones.” Dr Woolley identified them as belonging to the Monstersauria—a group of lizards with a 100-million-year history, but until now an incomplete fossil record. A modern member of this group is the Gila Monster, one of only two venomous lizards alive today. The fossil, belonging to a large-bodied lizard which Dr Woolley has named Bolg amondol after a character in J.R.R. Tolkien’s The Lord of the Rings, was found in the Kaiparowits Formation of the Grand Staircase–Escalante National Monument, Utah—a palaeontological treasure trove and one of North America’s richest dinosaur-dominated records. Alongside dozens of new species, the site offers a vital window into the deep past. The age of this fossil places it squarely in the age of the dinosaurs, a crucial factor in lizard evolution.

Incidentally, the picture above shows the Kaiparowits Formation. Perhaps a creationist would like to explain how those vast sedimentary strata could have been deposited in a single global flood.

Dark ages: Genomic analysis shows how cavefish lost their eyes | Yale News

Some days there are so many papers in which the authors casually — and with no intention of doing so — comprehensively refute basic creationist claims, that there just aren’t enough hours in the day to keep up with them. For creationists, of course, the task is simple: never read a scientific publication. The last thing any dedicated creationist wants is those pesky, “Satanic” scientists trying to make them lose ‘faith’, or worse, consider the possibility of being wrong when confronted with nasty, toxic facts.

In the bizarre world of faith, things must be true if you believe them by faith. After all, faith is the sure and certain way to “just know” the truth without all that bothersome learning. It’s also the sure and certain way to know that yours is the only true faith and that all other faiths are wrong.

So this new research about the convergent evolution of blind cavefish will need to be kept firmly behind the impregnable shield of faith, because faith must be protected from cold, harsh reality at all times — even at the cost of personal integrity. A creationist would much rather be thought of as intellectually dishonest than wrong.

The news comes from researchers at Yale, who have discovered how blind cavefish lost their eyes through something creationists insist can’t happen because it is invariably fatal: loss of genetic information. And not just once, but in several species of blind cavefish — all of which lost their eyes by essentially the same mechanism.

The researchers showed, using a new “mutational clock,” that the oldest blind cavefish, the Ozark cavefish (Troglichthys rosae), began degenerating up to 11 million years ago. This technique also establishes a minimum age for the caves these fish inhabit, since the caves must have existed before the fish colonised them.

In a nice confirmation of the Theory of Evolution — which predicts that environmental change will drive evolutionary change and that species will evolve towards greater fitness in that environment — several species of cavefish exhibit broadly similar adaptations such as a flattened skull, a long, thin body, and the loss or reduction of pelvic fins.

Refuting Creationism - Another Fossil; Another Thorny Problem for Creationists

“Bizarre” armoured dinosaur, Spicomellus afer, had spikes sticking out from its neck, fossils show - University of Birmingham

A newly-identified bizarre dinosaur fossil from Morocco has presented creationists with yet another thorny problem to ignore.

It is that of an ankylosaur from early in the evolutionary history of that group. Not only is its great age a problem for those who believe Earth was magicked into existence by a god with all living things fully formed and an environment perfectly tuned for life (i.e. human life — supposedly the god’s favourite), but at 165 million years old it comes from the vast span of Earth’s pre-“Creation Week” history — that 99.9975% of the planet’s history which creationists pretend never happened. This is, in fact, the oldest ankylosaur yet discovered.

Unlike later ankylosaurs, however, this one had long spikes firmly attached to its bones. These appear to have been lost as the group evolved, showing relatively rapid change. That in itself runs counter to the creationist dogma that evolution cannot proceed by loss of genetic information and must always involve increasing complexity for it to be “real” evolution. This claim, like so many creationist assertions, ignores abundant evidence — such as the reduction in genome size and anatomical complexity in many endoparasites.

Now they have yet another example to ignore while busily constructing their infantile strawman versions of evolution to attack.

The discovery by palaeontologists co-led by Professor Susannah Maidment of Natural History Museum, London, and the University of Birmingham, has just been reported in Nature and is explained in a news item from the University of Birmingham and an accompanying YouTube video:

Chemists recreate how RNA might have reproduced for first time | UCL News - UCL – University College London

The day creationists dread — the final closure of their favourite god-shaped abiogenesis gap — moved a little closer last May, when scientists at University College London (UCL) announced that they had shown how the first RNA could have reproduced. In a selective environment with competition for resources, this would have led inevitably to ever-increasing efficiency in replication, kick-starting the whole evolutionary process and the emergence of self-organising systems (or “life”) from prebiotic precursors (or “non-life”). This is, of course, the very process that creationists insist is “impossible”, clinging to the idea that “life” is some magical essence that must be granted by a supernatural deity.

When this God-shaped gap is finally and conclusively closed — as all the others have been — creationists will need to scramble once again to reframe their beliefs and cling to whatever shrinking space remains for their god. Just as their old claim that evolution was “impossible” collapsed, to be replaced with notions of a short burst of warp-speed evolution “within kinds” after “The Flood” (and supposedly still happening today, but conveniently “guided” by God), so too will abiogenesis inevitably be rebranded as yet another process directed by divine intention — naturally, with the eventual production of (American) humans as the goal.

New crocodile-relative “hypercarnivore” from prehistoric Patagonia was 11.5ft long and weighed 250kg | EurekAlert!

Seventy million years before creationists believe the universe even existed, a ferocious crocodile was prowling the rivers of what is now Brazil. Its fossil remains, recently described in an open-access paper in PLOS One and summarised in a press release from EurekAlert, add yet another line to the mountain of evidence that life has a vast, deep history stretching back hundreds of millions of years.

For creationists, however, discoveries like this present a problem. To remain in the cosy confines of their self-referencing dogma, they must either ignore such evidence or twist it into their narrative that evolution is a Satanic lie and the universe is only a few thousand years old because the Bible says so. Their mission, as they see it, is to defend God’s revealed truth from the “deceptions” of science.

But even if one accepts, for the sake of argument, that a god created the universe and a demonic adversary named Satan exists, the logic collapses under its own weight. Surely it would have been easier for Satan to forge a single book than to fabricate all the astronomical, geological, radiometric, genetic, and fossil evidence pointing to an ancient universe and the evolutionary diversification of life. The alternative is that the creator itself deliberately falsified the evidence science uncovers—yet creationists prefer to believe that this same deceiver told the truth in just one book.

And so the walls of the creationist cult remain, impervious to evidence. But outside those walls, science continues to reveal the true story of life on Earth, in discoveries like this ancient crocodile from long before “Creation Week”—from a time when, according to creationist belief, nothing at all should have existed.

Malevolent Design - How a Spider Uses Captive Fireflies To Lure More To Their Death - Malevolence or Evolution?

Sheetweb spiders have outsourced prey attraction to their prey's own signals.

Firefly caught in a sheetweb spider's web

Spider uses trapped fireflies as glowing bait - BES

This news will thrill devotees of a creationist god of divine malevolence; but for those who prefer their deity to resemble the all-loving god of the New Testament, it will be a cause for concern. Even more worrying for the latter, the current campaign by creationist organisations such as the Discovery Institute—trying to promote the pseudoscience of Intelligent Design as a scientific alternative to evolutionary biology—unwittingly strengthens the case for a malevolent designer. After all, Michael J. Behe’s notion of irreducible complexity and William A. Dembski’s concept of complex specified genetic information apply just as well to parasites and stealth predators as they do to supposed “beneficial” features such as human intelligence or the biological systems that keep us alive.

The latest example comes from scientists at Tunghai University, Taiwan, who have shown that a sheet-web spider has evolved a particularly nasty trick for luring fireflies to their deaths. The method is brutally simple: once the spider captures a firefly, it keeps it alive, so its flashing courtship signal continues to glow. Instead of attracting a mate, the unfortunate insect draws more fireflies into the spider’s web—and to certain death.

To an evolutionary biologist, this is a fascinating demonstration of how a mindless natural process can hone behaviour in whatever direction produces more offspring, regardless of whether humans judge the outcome “good” or “evil.”

This image, which combines infrared data from the James Webb Space Telescope with submillimetre observations from the Atacama Large Millimetre/submillimetre Array (ALMA), shows the doughnut-shaped torus and interconnected bubbles of dusty gas that surround the Butterfly Nebula’s central star. The torus is oriented vertically and nearly edge-on from our perspective, and it intersects with bubbles of gas enclosing the star. The bubbles appear bright red in this image, illuminated by the light from helium and neon gas. Outside the bubbles, jets traced by emission from ionised iron shoot off in opposite directions.

JWST observations of Butterfly Nebula reveal how cosmic dust is made in space - News - Cardiff University

There’s a double whammy for creationists in this new paper. Not only does it expose the Bible’s description of the Universe as laughably naïve, but it also shows how organic molecules — in the form of polycyclic aromatic hydrocarbons (PAHs) — that may have formed the basis of life on the prebiotic Earth, could have been created in deep space and later incorporated into our planet either at its formation or via impacts from space debris.

The paper, by a team of scientists led by Cardiff University, has just been published in Monthly Notices of the Royal Astronomical Society. Using data from the James Webb Space Telescope (JWST), the researchers reveal how stars generate space dust, organic material, and the fundamental building blocks from which rocky planets like Earth are formed. Their study focuses on the Butterfly Nebula (NGC 6302), a spectacular stellar remnant.

What Are PAHs?

Polycyclic aromatic hydrocarbons (PAHs) are complex organic molecules made of fused benzene rings — essentially arrangements of carbon and hydrogen in hexagonal patterns. On Earth, they are often associated with combustion (for example, in car exhaust fumes, cigarette smoke, or charred food). In space, however, they form naturally in the outflows of dying stars and in the dense molecular clouds that give rise to new stars and planetary systems.

PAHs are of great interest to astrobiologists because they are thought to be among the earliest organic compounds to have existed in the Universe. They can undergo chemical transformations to form more complex molecules, including amino acids and nucleotides, which are the essential components of life. Their presence in meteorites and interstellar dust suggests that the seeds of life were widespread long before Earth even formed.

Refuting Creationism - Oceanic Oxygenation Spured Rappid Evolution - 390 Million Years Before 'Creation Week'

How oxygen made the deep ocean home to animals, spurring rapid evolution | UW News

Another wave of reality breaks over the impervious rocks of creationist dogma, in the form of news that an international team of researchers led by the University of Washington has shown a correlation between the rapid radiation of marine vertebrates and the evolution of plants on land. As trees and other vascular plants spread, more atmospheric carbon became locked into their woody stems, reducing carbon dioxide levels. At the same time, increased photosynthesis raised atmospheric oxygen levels, which in turn oxygenated the oceans, making oxygen available in depths that had previously been anoxic.

Creationists will, of course, need to ignore the fact that this finding flatly contradicts their claims that evolution only occurs within “kinds” and that all diversification happened in a brief burst of warp-speed evolution following a genocidal global flood some 4,000 years ago. The timeline alone is utterly inconsistent with their favourite creationist fairy tale.

Scientists once believed this major oxygenation event had occurred about 500 million years ago, but the new research shows that episode was short-lived. A more significant oxygenation occurred around 390 million years ago. Initially, oxygenation would have taken place in shallow coastal regions where vertebrates first evolved. As oxygen penetrated deeper into the oceans, vertebrates followed into the newly opened niches, leading to a rapid proliferation of jawed vertebrate species — the ancestors from which terrestrial tetrapods later evolved.

The team reached their conclusions after measuring selenium isotopes in 97 sedimentary rock samples from five continents, dated between 252 and 541 million years ago. These rocks had been deposited near the edges of continental shelves, where shallow seas transition into the deep ocean. Selenium occurs naturally in several isotopic forms, and the ratios in which they were deposited depend on the level of oxygen dissolved in seawater. These isotopic signatures thus provide an indirect measure of oxygenation levels at the time the rocks were laid down.

2025: Ancient squid-like creatures are not squid after all, study finds | School of Biological Sciences | University of Bristol

The bad day for those creationists who haven't yet closed their minds to contrary information continues. Close on the news of a 220-million-year-old fossil ichthyosaur from Japan comes the discovery of a 500-million-year-old fossil worm from Greenland.

The identification of this Cambrian fossil, Nectocaris, as an ancestor of arrow worms rather than an early squid, as once thought, is a fine example of something creationists pretend to find incomprehensible: scientists changing their minds when new evidence demands it. Wedded to simple certainties, right or wrong, creationists insist that science must be either wholly right or wholly wrong. If a conclusion is shown to be mistaken, they assume the entire scientific enterprise collapses into a cloud of vacuous uncertainty. In their black-and-white world of false dichotomies, that somehow means their evidence-free superstition wins by default.

About 15 years ago, a study of fossils from the Burgess Shale concluded that Nectocaris was a cephalopod mollusc. But that classification posed problems since what could be discerned of its anatomy did not match that of cephalopods. That difficulty has now been resolved by a detailed examination of the ventral ganglion – part of the nervous system – which is revealed to consist of paired structures consistent with being ancestral to arrow worms.

This breakthrough was made possible by the exceptional preservation of fossils at Sirius Passet in northern Greenland, a remarkable Cambrian fossil site.
