Refuting Creationism - Yet Another of Those 'Non-Existent' Transitional Fossils - From 150 Million Years Before 'Creation Week'

Not All Early Birds Evolved Toward Better Flight, Jurassic Fossil Suggests----Chinese Academy of Sciences

Creationists who insist that there are no transitional fossils might wish that palaeontologists would stop finding animals that refuse to respect their imaginary boundaries. A newly described Jurassic bird from China is another such inconvenience: an evolutionary mosaic combining bird-like features with conspicuously dinosaurian anatomy. And, to compound the difficulty for Bible literalists, it lived approximately 150 million years ago — long before their supposed ‘Creation Week’.

The animal, Yuezhuornis yangyuanensis, discovered in the Late Jurassic Zhenghe Fauna of Fujian Province, is described in a paper published in Nature. This crow-sized animal possessed bird-like pelvic and hindlimb features alongside serrated teeth and a hyperextensible second toe bearing a sickle-shaped claw — a combination reminiscent of its close dinosaurian relatives.

Its unusually short forelimbs provide another intriguing part of the story. Analyses of its limb proportions strongly support a terrestrial, flightless lifestyle, despite its placement within Avialae, the evolutionary group containing living birds and their closest extinct relatives. The researchers interpret it as evidence of exceptionally early flight loss. That interpretation necessarily involves reconstructing ancestral capabilities: the fossil provides anatomical evidence about how this animal lived, rather than a direct record of either its behaviour or its ancestors’ flight.

This matters because evolution has no destination. Early birds were not obliged to become progressively better flying machines, any more than every mammalian lineage was obliged to become a bat. Natural selection favours traits according to their consequences in particular environments; it does not work towards a predetermined ideal. A lineage exploiting opportunities on the ground could follow a different evolutionary course from one increasingly dependent on flight.

Creationism Refuted - How Cephalopods Evolved Intelligence - No Magic Needed

3D structure of DNA may explain how cephalopods evolved complex brains

How much new DNA does evolution need to produce a new biological capability? Intelligent design creationists commonly assume that new functions require new “complex specified information”, then insist that only an intelligent designer can supply it. But this overlooks something fundamental about genomes: what matters is not simply which genes an organism possesses, but how, where and when those genes are used. Rearranging existing components can change what a biological system does, without requiring every component to be invented afresh, and, importantly, no new DNA being inserted into the genome.

A new study published in Nature Communications explores this possibility in coleoid cephalopods — octopuses, squid and cuttlefish. These animals have elaborate nervous systems and remarkable behavioural capabilities. The research suggests that part of the explanation for their evolutionary innovations may lie in the three-dimensional organisation of their genomes.

DNA does not lie inside a cell as a neatly stretched-out sequence. It folds, bringing regions that are distant along a chromosome into physical proximity. Those contacts can influence gene regulation. An ancient episode of extensive genome rearrangement in the ancestors of coleoids created opportunities for previously separated regions to acquire new regulatory relationships. The researchers describe the resulting interdependence as “regulatory entanglement”.

Comparing genome organisation and gene activity across species, tissues and developmental stages, the team found a combination of stability and flexibility: larger chromatin domains were broadly conserved, while hundreds of smaller DNA loops varied with species and biological context. Their experiments also went beyond comparisons: deleting a candidate regulatory sequence using CRISPR–Cas9 demonstrated a role for these long-range interactions in neural development.

This is not proof that genome rearrangement alone produced cephalopod intelligence, nor does it mean that no new DNA evolved. The study also considers genome expansion. Its importance is more interesting than either oversimplification: evolutionary novelty can involve changes in the relationships between genetic components, as well as changes to the components themselves.

That leaves the intelligent design argument with a familiar problem. Calling a biological outcome “information” does not demonstrate that it required a supernatural author. Here, scientists are investigating physical mechanisms through which genome evolution can generate new regulatory possibilities. Whether creationists choose to call those possibilities “new information” changes neither the mechanisms nor the evidence. The scientific question is how complexity evolved — and this research offers another testable part of the answer.

Refuting Creationism - Another New Dinosaur From The Isle of Wight For Creationists To Ignore

An artist’s illustration of the new theropod dinosaur, Invictibellatrix amberina (centre of the image), in its ecosystem on the Isle of Wight, United Kingdom in the Early Cretaceous (around 120 million years ago). It lived in what was likely a seasonally wet-to-dry floodplain environment and is surrounded by other dinosaurs including large long-necked rebbachisaurid sauropods (directly behind Invictibellatrix, centre) and relatives of Iguanodon (right). A spinosaurid theropod, potentially the apex predator of the time, fishes (left). Invictibellatrix has just caught and is consuming two small mammals. Gymnosperms dominate the environment as flowering plants (angiosperms) were not common at this time. Other reptiles including relatives to modern lizards, crocodiles and turtles enjoy the warm Early Cretaceous weather of the UK.

Palaeontologists do not need to set out to refute biblical creationism. They merely need to investigate the history of life, and the evidence does the job for them. Another example comes from the Isle of Wight, where a fossil has revealed a previously unrecognised predatory dinosaur that lived about 120 million years ago — long before the supposed ‘Creation Week’ of a literal reading of Genesis. While creationists struggle to squeeze the history of an entire planet into a few thousand years, researchers are reconstructing the evolutionary relationships and geographical movements of animals separated from us by immense stretches of geological time.

The fundamental problem creationists have created for themselves is that, because there is vastly more history pre-'Creation Week' than there is post-'Creation Week', by several orders of magnitude, virtually every palaeontological, geological and archaeological discovery incidentally refutes creationism, so the most risible and dishonest mental gymnastics have to be invoked to dismiss it all, and creationists end up looking both intellectually and morally bankrupt.

For example, as described in a study, published in Royal Society Open Science, a team led by University College London (UCL) researchers has identified Invictibellatrix amberina, the first recognised European member of a group of carnivorous dinosaurs known as megaraptorans. The discovery concerns a partial skull acquired by the Natural History Museum in 1924. CT scanning and anatomical comparisons have now revealed its significance. From its relatives, the researchers infer an animal around three to four metres long, probably feathered and equipped with substantial grasping arms and curved claws.

The discovery also helps fill a geographical gap in the group’s known distribution, supporting the hypothesis that megaraptorans dispersed from Asia through Europe towards the southern continents. This is the sort of question evolutionary science can investigate: how related animals diversified, where they lived, and how changing geography influenced their distribution. A fossil becomes evidence within a wider, testable account of life’s history.

Refuting Creationism - A Newly-Discovered Giant Fungus from A Family That Evolved 65 Million Years Before 'Creation Week'.

Scientists discover ‘D-rex’, a giant fungus from Chinese forests whose unique lineage dates back 65 million years | EurekAlert!

Another newly described species has brought with it an evolutionary history that refuses to fit into creationism’s abbreviated chronology. This time it is a giant fungus from China’s Yunnan Province, named Dianjunus rex, whose family lineage is estimated to have diverged about 65 million years ago — almost 65 million years before the supposed ‘Creation Week’ of young-Earth creationism. Apparently, this fungus’s ancestors failed to wait for the universe to be created.

Described in a new paper in Frontiers in Fungal Biology, the fungus produces imposing reproductive structures reaching 50 centimetres high and weighing up to 2.2 kilograms. Its anatomy and genetic relationships justified the recognition of not merely a new species and genus, but a new family: Dianjunaceae.

The date needs a little care. The researchers are not claiming that today’s species has remained unchanged for 65 million years. Their evolutionary analysis estimates when its family lineage separated from its closest relatives, with a reported range of approximately 50–80 million years. That uncertainty is scientifically significant, but offers no refuge for biblical literalism: even the youngest end of the range is vastly older than the entire history permitted by a young-Earth reading of Genesis.

There is a further irony here. Genesis offers no recognition of fungi as a distinct group of organisms. Although biblical passages refer to conditions translated as mould or mildew, these are hardly an account of fungal biology or evolutionary relationships. We cannot know that the authors simply assumed mushrooms were plants, but we can say that their creation narrative supplies none of the distinctions needed to understand this discovery. That is unsurprising in an ancient religious text; it becomes a problem only when that text is presented as authoritative natural history.

Unintelligent Design - The Prolific Waste of Spawning Coral

Spawning coral release quintillions of eggs each year: new research
spawning coral on the Great Barrier Reef, Australia
One of the most conspicuous features of the living world is its reproductive extravagance. Organisms manufacture enormous quantities of eggs, sperm, seeds and spores, only for the overwhelming majority to leave no descendants. Coral spawning provides a spectacular example: an underwater blizzard of reproductive material, produced at considerable biological expense, from which only a tiny fraction will ultimately contribute to the next generation of breeding corals. If this is intelligent design, its designer appears remarkably comfortable with failure on an industrial scale.

New research by M. M. Bilodeau and K. M. Quigley, published in Ecology and Evolution puts a staggering figure on this reproductive output. The researchers estimate that Indo-Pacific corals could produce approximately 3.46 quintillion eggs — 3.46 × 1018 — during a single hypothetical spawning period. This is a first approximation based on reproductive traits and coral cover, with missing measurements estimated from other traits. It is neither a direct count nor a precise total for all coral reproduction worldwide each year.

Each egg and sperm normally carries one set of chromosomes: half the usual chromosome complement of the parent’s body cells, including a reshuffled selection of its inherited genetic variants. Producing these cells requires resources, and eggs also contain provisions for early development. Yet many gametes never achieve fertilisation, while many resulting larvae fail to establish themselves and survive to reproductive maturity. The study estimates the scale of egg production, not the precise proportion lost, but the distinction between producing eggs and producing successful descendants is fundamental.

Creationism In Crisis - A Jurassic Crocodile With Needle Teeth - 170 Million Years Before 'Creation Week'

New species of Jurassic crocodile had unusually slender teeth | University of Portsmouth

Some 170 million years ago, in the rivers and lakes of what is now Morocco, a crocodile relative was exploiting a feeding niche very different from that of the large-prey predators familiar today. Named Ctenosuchus tenuidens, it had a long, narrow snout armed with exceptionally slender, closely spaced teeth. For young-Earth creationists, its existence presents the familiar chronological problem: an animal was living, feeding and participating in a complex ecosystem more than 169 million years before their preferred biblical chronology allows Earth itself to have existed.

The discovery is described in a paper in the Journal of Vertebrate Paleontology by Hamzah Imran of the School of the Environment and Life Sciences, University of Portsmouth, and colleagues. The animal belonged to the thalattosuchians, an extinct group of crocodile relatives. Its delicate dentition suggests a diet of small aquatic prey, such as tiny fish, shrimps and worms, rather than large, struggling animals capable of breaking those fine teeth.

This makes the fossil particularly informative about evolutionary specialisation. Teeth are not simply more or less effective in some universal sense: their usefulness depends on what an animal eats and how it feeds. A robust tooth suited to restraining substantial prey and a fine tooth suited to retaining small organisms represent different solutions to different ecological problems. An adaptation can therefore open up one feeding opportunity while limiting another. Evolution produces such compromises because natural selection favours reproductive success under particular conditions, rather than engineering an organism that excels at everything.

New crocodile species discovered in rocks used to build the Great Sphinx | UCL News

The Great Sphinx of Giza is an ancient monument carved into something vastly more ancient: rocks recording a world that existed long before humans, let alone Egyptian civilisation. A newly recognised crocodilian from the same geological formation lived about 45 million years ago. For anyone attempting to reconcile Earth's history with a literal reading of Genesis and its young-Earth chronology, the difficulty begins with the material from which the monument itself was carved.

As UCL News reports, researchers have identified Herugavialis cairensis, an extinct gavial, or long-snouted crocodilian, from Egypt's Mokattam Formation. Its nearly complete skull was discovered in the 1920s and had long been assigned to Tomistoma, the genus containing today's false gharial. CT scanning revealed distinguishing anatomical features, including a raised ridge around the eyes, supporting its recognition as a separate genus. The findings are published in Royal Society Open Science.

This is a useful example of how science corrects itself. A fossil does not cease to be informative because it has spent a century in a museum, and an identification does not become unchallengeable merely because generations of researchers have accepted it. Better tools and renewed scrutiny can expose distinctions that earlier investigators missed. Revising the classification strengthens our understanding of evolutionary history; it does not undermine the evidence that such a history occurred.

The animal also belonged to a very different Egypt. Shallow seas covered areas that are now land, and several gavial species inhabited its coastal waters. UCL describes a wider Mediterranean history in which crocodilian diversity fluctuated alongside changes in temperature and sea level, before the region lost its crocodilians around the Mediterranean drying crisis roughly six million years ago. Even that much later episode predates the conventional young-Earth creationist date for the entire Universe by orders of magnitude.

Creationism In Crisis - How Breast Feeding Evolved - 165 Million Years Before 'Creation Week'

Professor Peishu Li coauthors Nature study uncovering ancient origins of mammalian suckling and swallowing

Some 165 million years before creationists imagine Earth existed, an aquatic relative of modern mammals was already carrying anatomical equipment associated with one of our most characteristic abilities: suckling milk. A newly described fossil from Inner Mongolia, China, adds another inconvenient chapter to the evolutionary history that young-Earth creationism insists never happened. Its significance extends beyond its age, however. It also preserves a revealing combination of ancestral and more modern features — precisely the sort of transitional anatomy that creationists routinely claim is missing from the fossil record.

The animal, Megacauda sungei, is described in a new paper in Nature. It belonged to the docodonts, an extinct branch of mammaliaforms, the broader group encompassing mammals and their closest extinct relatives. Living approximately 168–163 million years ago, it had a broad, flattened tail, swimming adaptations and specialised teeth suited to an animal diet. It was a functioning, specialised inhabitant of Jurassic freshwater environments, with an evolutionary history written into its anatomy.

Particularly informative are small bony projections near the back of the palate and specialised throat bones. In living mammals, comparable structures support the muscles and soft tissues involved in swallowing and suckling. Their presence in Megacauda suggests that important components of this feeding apparatus had already evolved by the Middle Jurassic. This does not mean that the fossil identifies the first animal to produce milk, or preserves a youngster caught feeding. The inference concerns the anatomical machinery that made mammal-like suckling and swallowing possible.

Refuting Creationism - The Earliest Aquatic Mammal Complete With Transitional Features - 120 Million Years Before 'Creation Week'

Reconstruction of the semi-aquatic life of Dongoconodon platycauda

Drawn by Chen Yu.
A joint study by Professor Bi Shundong of the School of Life Sciences at Yunnan University has discovered the earliest known swimming mammal to date.

Some 120 million years before anyone imagined a six-day creation, a small mammal in what is now northeastern China was combining features that refuse to fit the tidy categories creationists would like nature to obey. Dongoconodon platycauda had adaptations for swimming, an unusual pattern of tooth replacement, and an ear apparatus that retained a connection to its lower jaw. Here was a functioning animal with a mosaic of characteristics, illustrating how evolution modifies inherited structures without waiting for an entire collection of supposedly “mammalian” features to arrive together.

The nearly complete skeleton, from the Early Cretaceous Jiufotang Formation of Liaoning Province, is described by Shundong Bi and colleagues in Nature Communications. The research is also explained in institutional reports from Nanjing University and Yunnan University, both in Chinese.

Its broad hands and feet probably supported webbing, while its flattened, tapering tail appears to have helped with steering and stability. Comparisons with the skeletons of 124 living mammal species supported a semiaquatic lifestyle. This adds to the evidence that mammals living alongside dinosaurs occupied a much wider range of ecological niches than the familiar image of small, uniformly shrew-like creatures might suggest.

Creationism Refuted - A Previously Unknown Extinct Yak - Evolved 400,000 Years Before 'Creation Week'

Previously unknown extinct bovine species discovered in Siberia - Stockholms universitet

For young-Earth creationists, the problem with ancient DNA is that it keeps revealing histories which their preferred chronology cannot accommodate. The latest example is an extinct relative of the yak whose evolutionary separation from living yaks began at least 400,000 years ago — long before the supposed “Creation Week” of a literal reading of Genesis. Its existence has emerged from fragments of Siberian bone too incomplete to identify by their shape, but which retained something much more informative: genetic evidence of a lost branch of the bovine family tree.

In a study published in Current Biology, Jonas Oppenheimer, Alexandre Gilardet and colleagues report 20 ancient nuclear genomes from Denisova Cave and other sites in southern Siberia, spanning more than 200,000 years. The lineage, provisionally known as “yak X”, had previously been recognised from mitochondrial DNA. The new analysis provides much broader genetic evidence that it represented a distinct species that effectively separated from the lineage leading to living yaks by about 250,000 years ago.

This was no static population inhabiting an unchanging world. The genomes reveal a demographic decline and suggest population turnover, accompanied by reduced genetic diversity, around the last interglacial, approximately 130,000–115,000 years ago. Warming may have disrupted the distribution of these cold-adapted animals; an earlier warm interval may also have helped isolate populations during their initial divergence. Those climatic explanations remain hypotheses, but the genetic evidence provides a record against which they can be tested. The youngest specimen analysed is about 27,000 years old; precisely when, and why, the lineage subsequently disappeared remains unknown.

There is an equally instructive lesson in the researchers’ caution. Although they interpret the genomic evidence as identifying a separate species, they have not simply attached a new formal species name to these fragmentary remains. Comparisons with previously described yak-like fossils are needed to establish whether the genetic lineage corresponds to an animal already recognised from its anatomy. Discovering a previously unrecognised genetic history and resolving its taxonomic identity are related but distinct tasks. Scientific confidence in one does not require pretending that the other has already been settled.

For creationism, meanwhile, calling the animal “just another member of the cattle kind” does nothing to resolve the chronological problem. The evidence concerns a branching history of populations, divergence and eventual extinction extending across hundreds of thousands of years. Evolutionary biology supplies the framework for reconstructing that history and asking further questions about it. Compressing everything into a few thousand years would require an alternative explanation for the genetic relationships, the ages of the remains and the succession of populations — not merely a biblical label applied after the evidence has been collected.

Malevolent Design - How Ancient Viral DNA Gave Humans An Advantage But Can Be Co-Opted By Lung Cancer - Malevolent Design, Incompetence or Evolution?

An ancient advantage, hijacked by cancer | Crick

Some 13 million years before anyone could have written a creation myth, a retrovirus inserted its genetic material into the genome of an ancestral ape. Today, part of that viral legacy helps regulate early human development. This presents creationists with several difficulties at once: a history vastly older than their biblical chronology permits, genetic material acquired from a virus, and an evolutionary innovation produced by putting an existing sequence to a new use. There is also an uncomfortable sting in the tail for advocates of a benevolent intelligent designer: cancer cells can exploit the same biological machinery.

The research, reported in Science Advances, concerns a remnant of an ancient retrovirus known as HERVH. This sequence acts as a switch controlling a form of calbindin, a protein involved in buffering calcium inside cells. Removing the switch or calbindin disrupted the growth and developmental behaviour of human embryonic stem cells and the organisation of models of early embryonic structures.

The evolutionary distinction matters. The original acquisition of viral DNA represents horizontal genetic transfer: genetic material crossed from a virus into its host, rather than arriving through ordinary inheritance from a parent. Once incorporated into the germ line, however, that material could pass vertically through successive generations. Its recruitment to regulate a host gene is an example of exaptation — the co-option of an existing feature for a different function. The virus did not need to invent calbindin, nor did evolution need to create an entirely new protein from scratch. A new regulatory relationship could arise by combining material with different evolutionary histories.

This is precisely the sort of process obscured by the creationist slogan that new genetic “information” requires an intelligent author. Biologically useful novelty can involve changes in when, where and how an existing gene is expressed. Imported DNA can supply a regulatory element; subsequent evolution can preserve and modify its contribution. Calling the result “information” does not erase the natural processes that produced it, still less establish that someone intended the outcome.

The chronology is equally inconvenient. Comparative primate evidence places this insertion roughly 13 million years ago, after the lineage leading to humans and the African great apes had separated from the orangutan lineage. Orangutans are themselves great apes; the relevant event occurred within the broader great-ape family tree. Either way, this is inherited molecular history extending far beyond the few thousand years allowed by a literal young-Earth reading of Genesis.

Yet a mechanism useful during development need not remain beneficial in every context. Earlier research showed that lung squamous cell carcinoma can activate this viral switch, helping cancer cells avoid senescence — a state in which cells stop dividing. The cancer biology is complex, but the central evolutionary point is clear: machinery that supports normal development can also become available for malignant cells to exploit.

That is consistent with an evolutionary cost-benefit trade-off. Natural selection can preserve a developmental advantage despite a vulnerability elsewhere in life; it has no foresight with which to guarantee lifelong protection from every possible consequence. But if intelligent-design advocates insist that useful genetic arrangements demonstrate deliberate engineering, they must apply that reasoning consistently. A designer credited with the developmental benefit cannot simply be excused responsibility for the exploitable weakness. On their own premises, the result raises questions about competence, benevolence, or even malevolent design. Evolution requires no such theological contortions: an ancient infection, inherited variation and the opportunistic reuse of existing material are sufficient ingredients for the story.

Creationism Refuted - Polynesian Genetics Refute Biblical Mythology And Confirm Evolutionary Theory

Polynesian Wayfinding Is Written in the Genomes of Island Populations

Human history is written in more than ancient texts. It is also preserved in the genetic material passed from generation to generation, where migrations and changes in population size leave patterns that scientists can investigate. For creationists who would compress humanity’s ancestry into the descendants of a single family emerging from a mythical global flood, this presents a demanding test: their story must explain the actual distribution of genetic variation, rather than merely assert that people dispersed.

A new study published in Science on 8 October 2026 examines whole-genome sequences from 1,050 Polynesian people. It reveals successive founder effects associated with the settlement of Pacific islands: small founding groups carried only part of their source population’s genetic diversity, and subsequent departures repeated that sampling process.

The result is a nested pattern of inheritance. Particularly striking is the close genetic relationship between the populations of Hawaiʻi and Rapa Nui, despite their separation by roughly 7,000 kilometres. The researchers interpret this as evidence that both populations have deeper ancestral roots in Mangareva. Their reconstruction also involves repeated movement between islands, rather than a simple procession of isolated, one-way journeys.

These demographic events have medical consequences too. Variants that were rare in an ancestral population can become relatively common among descendants of a small founding group. The study identifies several disease-associated variants at elevated frequencies, showing how the legacy of settlement can remain relevant to health today.

This is also an accessible example of why evolution cannot be reduced to natural selection alone. Genetic drift — chance changes in the frequencies of genetic variants — can shape populations without making them better adapted. A variant does not have to be beneficial to become more common; sometimes its frequency reflects who happened to found a community and which descendants subsequently reproduced. The voyages were purposeful human achievements, but their genetic consequences required neither foresight nor a designer.

The challenge for biblical literalism is therefore more substantial than finding room for Polynesian voyagers somewhere after Noah. A scientific explanation must account for which populations share particular variants, how those variants are distributed, and which demographic history best explains the pattern. These findings do not, by themselves, constitute a test of every claim about a global flood. They do demonstrate what an evidence-based account of human dispersal looks like: a reconstruction open to scrutiny and revision, with consequences that can be checked against independent evidence. Simply invoking Genesis supplies none of that explanatory detail.

Refuting Creationism - More Problems for Creationists As Science Reveals Yet More Evidence Falsifying The Bible Creation Myth

New study suggests animals may have evolved vastly earlier than fossil evidence suggests | Oxford University

One of the strengths of science is that its conclusions remain open to revision. An assumption that once appeared reasonable can be tested against new evidence, found wanting, and replaced with something better. For creationists, who frequently portray such revisions as evidence that science cannot be trusted, this must seem a peculiar way of acquiring knowledge. Yet it is precisely how science improves its understanding: by allowing the evidence to correct the explanation, rather than requiring the evidence to conform to a predetermined answer.

A new study published in Science Advances provides another example. Researchers have challenged an assumption used in some recent estimates of when animals originated. Their analyses support an origin approximately 700–800 million years ago, potentially extending animal evolutionary history by around 200 million years beyond estimates based on a younger maximum-age constraint.

The issue is a deceptively simple one: if a fossil deposit preserves microscopic organisms in exquisite detail, but contains no definite animals, does that mean animals had not yet evolved? Some researchers have used the approximately 590-million-year-old Weng’an Biota of China in this way, reasoning that animals would have been preserved there had they existed. Its lack of unequivocal animal fossils has therefore helped set a proposed upper age limit for animal origins.

The new research exposes a difficulty with that reasoning. The younger Kheseen Biota of Mongolia also preserves exceptionally detailed microfossils, yet none can confidently be identified as animals. In this case, however, animals are known from other deposits of comparable age. Their absence from Kheseen therefore cannot demonstrate their absence from the world. Particular environments and conditions of fossilisation can leave animals out of the record, even when other organisms are beautifully preserved.

This matters because molecular clocks — methods that use genetic differences between living organisms to estimate when their ancestors diverged — require calibration against geological and fossil evidence. Change an unjustified age constraint, and the resulting estimates can change substantially. Using alternative constraints from older deposits, the researchers recovered a much earlier possible origin for animals. They have not discovered an 800-million-year-old animal, nor established a final date for the animal kingdom’s beginnings. They have shown why one argument for restricting those beginnings to a much later interval is unreliable.

For young-Earth creationism, neither chronology offers any comfort. The debate concerns events hundreds of millions of years ago, not whether animal history can be squeezed into the few thousand years allowed by a literal reading of Genesis. Uncertainty over precisely when animals originated does not make every proposed date equally credible, any more than uncertainty over a mountain’s exact height makes it plausibly a molehill.

Revolutionary Feathered Dinosaur Discovery in China Suggests Flight Evolved Multiple Times : ScienceAlert

For creationists who insist that complex adaptations could only have appeared as complete, purpose-built packages, another feathered dinosaur has provided an awkward piece of evidence. Evolution does not require a finished flight apparatus to materialise in a single miraculous leap. It can modify inherited structures, combine them in new ways, and produce similar adaptations along different branches of the family tree. A newly described dinosaur from China adds evidence that even among the close relatives of birds, there was more than one evolutionary route towards an aerial lifestyle.

In a paper published in Nature Communications, Xuri Wang and colleagues describe Norellraptor barsboldi, a small microraptorine dinosaur from the Lower Cretaceous Jiufotang Formation of Liaoning, north-eastern China. Its remarkably complete, 57-centimetre skeleton preserves traces of plumage, including on its forelimbs and hindlimbs. It belonged to the group of feathered dinosaurs famous for their four-winged forms: evolutionary relatives of birds, rather than evidence that modern birds appeared fully formed and unrelated to other dinosaurs.

The crucial finding concerns the sequence in which adaptations arose. The researchers’ evolutionary analysis indicates that approximately 30 per cent of the derived anatomical features identified in microraptorine evolution also evolved independently in the bird lineage. However, they appeared in different orders. This supports the gradual assembly of flight-associated anatomy under different selective pressures, rather than the inheritance of an already completed flight apparatus from a common ancestor.

Fossils confirm human ancestors first appearance, News, La Trobe University

Two million years ago, southern Africa was home to different human relatives sharing the same landscape and following different evolutionary trajectories. That is the picture strengthened by newly described fossils from Drimolen Main Quarry in South Africa’s Cradle of Humankind. For creationists, the difficulties begin with the date: these hominins lived almost two million years before the supposed magical creation of the Universe out of nothing in a literal reading of Genesis. But the evidence also challenges the familiar caricature of human evolution as a single procession of increasingly human creatures, marching towards a predetermined destination.

In a paper published in Annals of Human Biology, Jesse M. Martin and colleagues describe 18 previously undescribed cranial and mandibular specimens from Drimolen. Among them is DNH 127, an adult skull fragment attributed to Homo erectus. This provides valuable support for the earlier identification of DNH 134, a young child’s partial skull from the same site. Identifying a species from an immature individual can be difficult because some diagnostic features develop during growth; an adult specimen provides an additional test of that interpretation.

The significance is therefore corroboration: DNH 127 strengthens the case that Homo erectus was present in South Africa approximately 2.04–1.95 million years ago. It does not, by itself, establish that the species originated there. The earliest fossil yet recognised is evidence of a species’ presence at a particular place and time, rather than a birth certificate identifying its evolutionary birthplace.

One of the recurring mistakes in creationist arguments is to assume that a complex biological system must always have performed its present function. If its components now work together, the argument goes, they must have been created together for that purpose. Evolution, however, can recruit existing machinery for new roles. Two papers in *Science* now provide evidence that this process may help explain the origin of an important form of microbial immunity—with the intriguing possibility that bacteria acquired the precursors of their antiviral weapons from viruses themselves.

To appreciate the discovery, it helps to understand what CRISPR immunity actually is. Although CRISPR is familiar as a tool for editing genes, its natural role is defence. Many bacteria and archaea possess CRISPR–Cas systems that retain molecular records of past invaders. Short pieces of foreign DNA are incorporated into the cell’s genome, between repeated sequences. These stored fragments provide templates for small RNA molecules, which guide CRISPR-associated—or Cas—proteins to matching genetic material during subsequent infections. Depending on the system, the resulting response can destroy invading DNA or RNA. This is adaptive immunity: protection directed against particular threats, with a genetic memory that can pass to descendants.

CRISPR stands for “clustered regularly interspaced short palindromic repeats”, a description of the DNA arrangement in which those memories are stored. The best-known gene-editing protein, Cas9, belongs to class 2, whose targeting machinery centres on one large protein. Class-1 systems instead use assemblies of several proteins to recognise their targets. It is the evolutionary origin of this latter machinery that the new research addresses.

The studies, published on 17 September 2026 investigate a compact system called VIPR, short for viral interference programmable repeat. Found in viruses and bacteria, it combines a small protein with a guide RNA. The researchers propose that an ancestral VIPR-like system involved in competition between viruses was recruited into bacterial defence, eventually contributing to the evolution of class-1 CRISPR. This would be evolutionary co-option: machinery favoured in one context becoming useful in another.

Malevolent Design - A Newly-Identified Tick-Borne Virus That Teams Up With Another Virus And Kills People - Malevolent Intelligence Or Evolution?

One of the problems with claiming that biological complexity proves intelligent design is that the argument cannot stop conveniently at butterflies, flowers and the human eye. If complex biological machinery requires a designer, then the same reasoning must apply to parasites and pathogens. A virus’s ability to infect us cannot become an unfortunate accident merely because crediting the supposed designer would now be embarrassing. Nor can the animal that carries it from host to host be excluded from the reckoning.

A newly identified tick-borne virus in China provides another uncomfortable example. Described in a correspondence in The New England Journal of Medicine, Asian longhorned tick nairovirus, or ALTNV, is associated with fever, fatigue, gastrointestinal symptoms and, in some patients, reduced platelet counts. Its vector is the already familiar Asian longhorned tick, Haemaphysalis longicornis; experiments demonstrated transmission to mice. “New” here means newly recognised by science, not shown to have come into existence recently.

The clinical findings deserve care. All 56 patients reported with ALTNV alone recovered without lasting effects. However, seven of 38 patients infected with both ALTNV and Dabie bandavirus died. These deaths do not establish that ALTNV alone is lethal, or determine its contribution to the fatalities. They do place the discovery within a system of tick-borne infections capable of causing serious illness and death.

Now apply the creationist rule that functional complexity and genetic information require an intelligent author. On that premise, the designer must take responsibility for the infectious agent and its means of delivery. Here is a blood-feeding animal whose activities provide a route for viruses to enter other animals, including humans. If every relevant adaptation was knowingly intended by an all-knowing creator, then the resulting suffering cannot be dismissed as an unforeseen side-effect. The alleged designer knew what its creations would do.

That is the force of the malevolent-designer argument. It does not require us to believe that a supernatural intelligence actually makes viruses. It asks why features that serve pathogens should count as evidence of loving craftsmanship when equivalent features serving their victims are routinely presented as precisely that. If the designer receives credit for our defences, it must also answer for the threats those defences sometimes fail to overcome. Deliberately creating the means of making people ill is hardly an obvious expression of benevolence.

Creationism Refuted - A Stem Amphibian from 309 Million Years Before 'Creation Week'.

One of the recurring problems for young-Earth creationism is that Earth’s history contains so much life before the supposed beginning of Earth’s history. A newly recognised fossil species from Illinois adds another example: a small, amphibian-like animal that lived approximately 309 million years ago, when the area around modern Chicago was a swampy river delta. That places it more than 300 million years before the creation event that biblical literalists insist accounts for all life on Earth. Explaining away a discrepancy of that magnitude requires rather more than pointing to an uncertainty in a scientific paper.

The animal is Jeanerpeton mazonensis, described by Allison J. Sefcovic, Payton J. Kohlberg and colleagues in a new paper in the Journal of Vertebrate Paleontology. Its recognition resulted from a fresh examination of a fossil already held in a museum collection. Previously assigned to Amphibamus grandiceps, the specimen proved sufficiently different in its skull and skeleton to warrant a genus and species of its own. The authors also suggest that other known specimens conceal more diversity among these early amphibamiforms than has previously been recognised.

The fossil comes from the exceptionally productive Mazon Creek deposits. Its preservation includes a body outline, scales, tiny abdominal skeletal elements called gastralia, and even impressions of the eyes. The genus honours the two student lead authors’ mothers, both named Jean. This is a reminder that important discoveries can begin with someone taking a closer look at a specimen collected long ago.

Of particular interest are structures previously interpreted as toe pads resembling those of living amphibians. Alongside the skeletal anatomy, such features help researchers investigate the combinations of characteristics present in these ancient animals. That does not establish Jeanerpeton as the direct ancestor of modern frogs or salamanders: resemblance and evolutionary relationship are not proof of direct ancestry. Its significance lies in adding another anatomically distinctive animal to the record against which explanations of amphibian evolution must be tested.

Why Science Works - And Creationism Fails - A Fossil From Mongolia Changes Scientific Minds, But Creationists Will Just Ignore It

One of the most revealing differences between science and creationism is what happens when new evidence challenges an established explanation. In science, that is an opportunity to improve our understanding. In creationism, where the conclusion has already been declared unquestionable, it becomes a problem to explain away. A remarkable fossil from Mongolia’s Gobi Desert provides a particularly instructive example: a small mammal whose combination of teeth, skull and limb bones has prompted scientists to reconsider an enduring hypothesis about mammalian evolution. Predictably, there is no comfort here for anyone hoping that revising an evolutionary family tree means abandoning evolution.

The animal, Tamirkhan balcarceli, is described in a paper in Nature by Andres Giallombardo and colleagues. Discovered in 2004, the exceptionally informative specimen preserves a skull and part of a hind limb. This provides something researchers had previously lacked for the enigmatic mammals known as zhelestids: teeth and substantial skeletal remains belonging to the same individual.

Until now, zhelestids were known principally from teeth and fragmentary jaws. Their relatively low, rounded molar cusps resembled those of plant-eating hoofed placental mammals, encouraging suggestions that they represented an early radiation of placentals during the Cretaceous. The new fossil tests that interpretation against a much broader sample of anatomy. Its zhelestid-like molars occur alongside distinctive incisors, skull structures and hindlimb features characteristic of another ancient mammalian group, the zalambdalestoids. The researchers conclude that zhelestids belong within that group. Their apparently revealing resemblance to later herbivorous placentals arose through convergent evolution.

The significance extends beyond moving a name from one branch of a family tree to another. Identifying which ancient mammals belong within the placental radiation helps establish when that radiation began and how its early members diversified. An animal can possess teeth resembling those of a later group without belonging to that group: similar feeding demands can favour similar dental adaptations in separate evolutionary lineages. More complete fossils allow researchers to distinguish those similarities from the wider anatomical evidence of ancestry. This discovery therefore changes how an important set of Cretaceous fossils contributes to the history of placental origins; it does not, by itself, settle every question about their timing.

For young-Earth creationists, the chronological problem remains as severe as ever. This is a Late Cretaceous mammal, part of a world that existed tens of millions of years before the few thousand years into which they attempt to compress the history of Earth and its inhabitants. Revising its evolutionary relationships does nothing to bring that world within the biblical timetable. Nor does a previously mistaken interpretation of its teeth supply evidence for separately created “kinds”. To establish that claim would require positive evidence of separate creation, not merely the discovery that one proposed relationship needs correction.

Tiny fossils found in 1.7 billion-year-old mud yield clues to the evolution of complex life

For young-Earth creationists, some of the most troublesome evidence comes in the smallest packages. Microscopic fossils preserved in ancient Australian mudstones record organisms living approximately 1.75–1.4 billion years ago — an antiquity impossible to reconcile with the few thousand years allowed by a literal reading of the biblical genealogies. These organisms were already part of aLayers of 1.7 billion-year-old sedimentary rocks, Kakadu National Park, Northern Territoryn evolving biosphere more than a billion years before the supposed “Creation Week”. Their existence presents a chronological problem that no amount of argument about the meaning of “kind” can resolve.

These fossils are the subject of a paper in Nature, by Maxwell A. Lechte and colleagues, investigating the environments inhabited by some of the earliest known eukaryotes. Eukaryotes are organisms with structurally complex cells, typically containing a nucleus and specialised internal compartments; they include animals, plants, fungi and numerous microscopic organisms. Here, “complex life” refers to cellular organisation, not to miniature animals swimming through those ancient seas. Understanding these early cells helps explain the evolutionary foundations upon which much later forms of life depended.
