Refuting Creationism - Filling Gaps In The Record - With Neanderthal Tools About 200,000 Years Before 'Creation Week'

Research paper: Insights into Neanderthal technological practices: Evidence of anthropogenic modifications on animal bones at the Abri 122/1200 Middle Paleolithic site (Eastern Carpathians, Romania)

One of creationism’s favourite tactics is to treat every apparent gap in the evidence as evidence of absence - although that never seems to apply to creationists' "God did it!" claims for which definitive evidence either for the god's existence or its actions are invariably absent. If archaeologists have not found something, creationists assume it never existed — or, more usually, that scientists cannot explain its absence without invoking the supernatural.

A study published in the Journal of Quaternary Science provides a neat illustration of what can really lie behind such gaps. In this case, the missing evidence was not missing at all. It consisted of thousands of small, unremarkable-looking fragments of animal bone that earlier archaeologists might easily have overlooked, discarded or left uncollected.

The study, led by Monica Mărgărit of Valahia University of Târgoviște, Romania, examined animal remains recovered from Abri 122/1200, a rock shelter in the Vârghiș Gorges of Romania’s Eastern Carpathians. The site contains an extensive Middle Palaeolithic stone-tool industry and abundant remains of animals, including bovids, goats, wolves and cave bears. Luminescence dating indicates that Middle Palaeolithic occupation extended across a long period, approximately from Marine Isotope Stage 7, about 230,000 years ago, into Marine Isotope Stage 3.

Among more than 10,000 bone fragments, the researchers identified 83 bearing combinations of impact damage, microscopic scratches, smoothing, polish and edge wear consistent with their having been used as tools. They distinguished these traces from damage caused by butchery, carnivore activity, sediment movement and other natural processes, using microscopic examination and comparisons with experimentally used bone fragments.

Some had apparently served as retouchers for shaping or sharpening stone tools. Others had been used to scrape or work softer substances such as hides or plant material, while still others had functioned as wedges, multipurpose implements or simple hammers. Most had not been laboriously carved into specialised shapes. A suitable fragment was selected, used for the task at hand and then discarded—an expedient but effective use of a readily available material.

That distinction is important. The discovery does not show that Neanderthals in Romania possessed an elaborate bone-working industry previously unknown to science. It shows something arguably more revealing about their everyday behaviour: they could recognise the useful properties of an ordinary fragment, adapt it to an immediate problem and employ materials other than stone as circumstances required. “Technologically flexible and resourceful” is therefore more accurate than the rather sensational claim that their technology was simply “more advanced”.

How Can Archaeologists Recognise an Expedient Bone Tool? A broken animal bone is not automatically a tool. Bones can be fractured, scratched, polished or crushed by many processes, including butchery, marrow extraction, carnivore gnawing, trampling, movement through sediment and weathering. Archaeologists must therefore distinguish evidence of deliberate use from damage produced before or after burial.

This study belongs to the field of traceology, or use-wear analysis. Researchers examine the position, orientation and microscopic structure of marks on an object to reconstruct how it may have been used.

Evidence of use

No single scratch or polished patch is normally decisive. Identification depends on combinations of features occurring in places where they would be expected on a working tool:
  • Localised smoothing and rounding can develop where an edge or projection has repeatedly rubbed against another material.
  • Microscopic striations may reveal the direction in which a tool was moved. Repeated scraping tends to produce organised wear rather than randomly orientated scratches.
  • Polish can develop through prolonged contact with relatively soft materials, possibly including hides or plant fibres.
  • Pits, grooves and small impact scars can indicate that a bone was used as a retoucher to shape or resharpen the edge of a stone tool.
  • Crushing, flaking and battered ends may identify bones used as hammers, wedges or intermediate pieces through which force was transmitted.

These marks must be distinguished from other forms of damage. Carnivore teeth can leave pits, punctures, scores and ragged edges; trampling can produce irregular scratches; roots can etch branching patterns into a surface; and movement through sediment can abrade an entire bone. Butchery and marrow extraction also produce characteristic cut marks, impact notches and fracture patterns. Those marks demonstrate human activity, but do not necessarily show that the bone was subsequently used as a tool.

Researchers compare archaeological specimens with experimental reference collections. Modern fragments of similar bone are used for scraping, rubbing, hammering, wedging or working stone. The resulting wear is then examined microscopically and compared with that preserved on the ancient specimens. Archaeological context, fracture history and the distribution of wear across each fragment provide additional evidence.

Even then, conclusions are expressed cautiously. Use-wear may show that a bone contacted a hard or soft material and indicate the kind of movement involved, but it cannot always identify the precise task or material with certainty.

Expedient and formally manufactured tools

A formal bone tool is deliberately manufactured. Its maker selects a suitable bone, produces a blank and modifies it by cutting, scraping, grinding or polishing. The finished object may have a regular shape intended for repeated or specialised use.

An expedient bone tool requires much less preparation. Its user recognises that an existing fragment already has a suitable edge, point, weight or shape, perhaps makes a minor adjustment, uses it for an immediate task and then discards it.

This does not mean that an expedient tool was accidental or that its user lacked the ability to manufacture something more elaborate. It represents a practical decision: there is little benefit in spending time making a specialised implement when a conveniently shaped piece of bone can perform the required task immediately.

Most of the specimens from Abri 122/1200 appear to belong to this expedient category. They were not extensively shaped, but their wear indicates that Neanderthals selected and used them as retouchers, scrapers, wedges, multipurpose implements or percussive tools. Their significance lies in the flexibility with which available materials were exploited, not in elaborate craftsmanship.

How archaeological gaps are created

Expedient tools present a particular problem because they can look like ordinary fragments of food waste. Earlier excavations often concentrated on complete, identifiable or visually impressive bones. Small fragments might be placed in storage without detailed examination—or not collected at all.

Consequently, an apparent absence of bone technology can reflect collection practices, preservation and the questions earlier researchers were asking rather than the behaviour of the people who occupied a site.

The Romanian evidence illustrates why gaps in the archaeological record should not be treated as proof that something never existed. Sometimes the missing evidence is already present, awaiting the methods and research questions needed to recognise it.
No Neanderthal skeletal remains have yet been recovered from Abri 122/1200, so the attribution is indirect. It rests on the age of the deposits, their Middle Palaeolithic stone industry and their wider archaeological context. The researchers are now looking for more direct evidence, including ancient Neanderthal DNA preserved in the cave sediments. This qualification is acknowledged openly by the scientists, unlike creationism, in which uncertainty is habitually concealed beneath declarations of dogmatic certainty.

The Romanian report in Gândul therefore describes more than another addition to the Neanderthal toolkit. The research demonstrates how apparent gaps in the archaeological record can be created by preservation, sampling and the questions researchers previously thought to ask. When those methods and questions improve, the gaps become smaller—not because scientists have invented missing evidence, but because they have learnt how to recognise evidence that was hiding in plain sight.
Auto-translated from Romanian:
Important discovery at a site in Romania. Neanderthals had more advanced technology than previously thought
Archaeologists have made an extremely important discovery right on Romanian territory. Specifically, in the site called Abri 122/1200, a cave in the Vârghiș Gorges occupied in the Middle Paleolithic, approximately 230,000 to 60,000 years ago, specialists have identified things that change what was known so far about the Neanderthals who lived on Romanian territory.
Researchers have identified, in bone fragments, the first evidence that they used bone tools for activities such as scraping, sharpening, or splitting.

The new study, led by Monica Mărgărit from the University of Târgoviște, was published in the Journal of Quaternary Science and focused on animal remains intentionally modified by humans. The researchers tried to determine whether the animal bones were simply remains from food consumption or whether, given the observed modifications, they were also transformed into tools for various activities, such as leather processing.

The context is particularly interesting because the Abri 122/1200 site preserves an important lithic industry and a large amount of faunal remains. Previous research has already identified bones from large herbivores, such as representatives of the bovid family, from the genera Bos and Bison, goats, but also the cave bear (Ursus spelaeus).

The bones show a high degree of fragmentation, compatible with the activities of cutting and exploiting the carcasses. During previous archaeological campaigns, fragments of long bones were discovered that appear to have been obtained by striking, most likely in the process of extracting the marrow. Some of the fragments also showed features compatible with their use as tools, geopop.it shows.

Important discovery on Romanian territory

The new study focuses on this aspect: the animal bones were not necessarily just food scraps. Traceological analyses showed that they were intentionally exploited. Some fragments could be selected and modified for use as tools, which demonstrates that Neanderthal technology was not limited to stone.

Although these fragments were not frequently processed or adapted for a very precise purpose, their shapes and characteristics appear to have been considered useful for carrying out certain activities.

The significance of the discovery goes beyond a single artifact. The intentional use of bones demonstrates a wider range of raw materials exploited by Neanderthals and suggests that, in addition to producing stone tools, these communities may have systematically used materials obtained from animal carcasses.

Abri 122/1200 is also an important site for understanding the presence of Neanderthals in the Carpathian region. The most recent research on the chronology of the site indicates that the archaeological levels with Middle Paleolithic industry could be up to about 230,000 years old.

The discoveries at Abri 122/1200 thus contribute to shaping an increasingly complex picture of Neanderthal technology: a system in which stone represented a fundamental raw material, but in which the bones of hunted and consumed animals could also become useful materials for carrying out technological activities.

ABSTRACT
Archeological evidence has demonstrated that Neanderthals utilized mammal bone remains as tools. These findings are geographically widespread, stretching from the Altai Mountains in Central Asia to the Atlantic Ocean. Such an extensive distribution is indicative of a broad pattern of Neanderthal behavior concerning tool use and resource exploitation, although a notable lacuna exists in the archeological record within the Carpathian region that appears as a blank area on the existing map. The main purpose of our study is to address and fill this geographical gap. To this end, we focused on the site of Abri 122/1200 in Romania as a representative case study. The luminescence dating results indicate that the Middle Paleolithic occupation of the cave spans from the Middle Pleistocene (Chibanian) to the Late Pleistocene, approximately from Marine Isotope Stage 7 (MIS 7, around 230 000 years ago) to MIS 3. A crucial aspect of our investigation involved differentiating between taphonomic marks on faunal remains: those resulting from natural processes such as scavenging or environmental factors and those stemming from technological activities like tool production or usewear. Through meticulous analysis, we successfully identified and isolated a consistent set of faunal remains categorized into five distinct typological groups. Our observations reveal that technological interventions on these bones are infrequent; the majority of fragments appear to have been used in their natural state without extensive modification. Fragments show evidence of being used in activities such as the processing of lithic tools, hides, or plant materials, which indicates a more complex utilization pattern than previously assumed. The assemblage from Abri 122/1200 thus exemplifies the importance of re-evaluating other Middle Paleolithic contexts within the Carpathian region. It highlights the variability, origin, and technological significance of bone production and utilization by Neanderthals, challenging traditional perceptions of their technological capabilities and resourcefulness.

The significance of these finds does not lie in the discovery of some spectacularly sophisticated Neanderthal invention. It lies in the evidence of adaptability preserved on apparently insignificant fragments of bone. The occupants of Abri 122/1200 recognised useful shapes and properties in the remains of the animals they exploited, selected suitable pieces for particular jobs and discarded them when those jobs were finished. This was practical problem-solving—the ability to use different materials flexibly rather than depend upon a rigid repertoire of stone implements.

The study also illustrates why creationist arguments based upon gaps in the evidence are so fundamentally dishonest. The apparent absence of Neanderthal bone tools from the Carpathian region did not mean that no such tools had existed. Many were too small and insufficiently modified to attract the attention of earlier excavators. Once researchers asked a more precise question, examined every fragment microscopically and compared its wear with experimentally produced marks, some of the supposedly missing evidence emerged from material that had been present all along.

Nor can the wider archaeological context be reconciled with a young Earth or a recent global flood. Abri 122/1200 preserves Middle Palaeolithic occupations extending through a substantial portion of the Pleistocene, within an independently dated sequence spanning tens of thousands of years. Its stone artefacts, butchered animal remains and expedient bone tools record repeated human activity long before creationists believe their god created the Universe, let alone before their mythical Flood supposedly destroyed the archaeological landscape. The absence of evidence does nothing for creationism; the presence of evidence utterly refutes it.

The researchers are also explicit about the limits of their conclusions. No identifiable Neanderthal remains have yet been found at the site, so the attribution rests upon its chronology, Middle Palaeolithic stone industry and wider European context. Instead of concealing that uncertainty, the team is looking for additional evidence, including ancient DNA in the sediments. That is how science works: conclusions are proportioned to the available evidence and remain open to refinement when new evidence appears.

Creationism predicted none of these discoveries, supplied none of the methods used to recognise them and offers no coherent explanation for their age or archaeological setting. Its only contribution is to rename Neanderthals as descendants of Adam or Noah and dismiss the dating, stratigraphy, genetics and comparative anatomy that show otherwise. Far from exposing a weakness in evolutionary science, the former blank on the Carpathian map demonstrates how science closes gaps, while creationism survives by pretending that every gap must remain permanent.

Refuting Creationism - How Humans Evolved, Migrated And Interacted In The Nile Valley - 34,000 Years Before Creation Week'

Research paper: Bony labyrinth morphology reveals deep population history and isolation among Homo sapiens in prehistoric northeastern Africa (44–3 ka) | Nature Communications

An international team of biological anthropologists has found a novel way to reconstruct tens of thousands of years of human population history in north-eastern Africa: by examining tiny variations in the shape of the bony cavities that once contained people’s inner ears. It's not good news for creationists so it'll be just one more thing for them to ignore one way or another.

The researchers, led by Nicolas Martin and Isabelle Crevecoeur of the PACEA laboratory at the University of Bordeaux and the French National Centre for Scientific Research (CNRS), have published their findings in Nature Communications.

The bony labyrinth is a complex system of cavities within the temporal bone of the skull. It surrounds the cochlea, involved in hearing, and the semicircular canals, involved in balance. Although its shape varies subtly between individuals and populations, much of that variation reflects inherited ancestry. High-resolution micro-CT scanning allows the labyrinth to be reconstructed and measured in three dimensions without damaging the remains.

This makes it especially valuable in regions such as north-eastern Africa, where heat and other environmental conditions have frequently destroyed ancient DNA. When molecular evidence is unavailable, the shape of the inner ear can preserve an anatomical record of biological relationships between ancient populations.

Martin and his colleagues analysed 194 bony labyrinths belonging to 148 individuals. Their sample included people who lived between approximately 44,000 and 3,000 years ago in the Middle Nile Valley, the Horn of Africa and Central Africa, together with comparative specimens from elsewhere in Africa, Europe and the Levant. The researchers applied three different methods of shape analysis, all of which produced the same broad patterns.

Those patterns reveal a long and complicated history of regional continuity, isolation, migration, interaction and partial population replacement. Late Pleistocene and Early Holocene hunter-fisher-foragers from the Middle Nile Valley showed broad morphological similarities both to one another and to still earlier African Homo sapiens. This is consistent with deep regional ancestry and substantial biological continuity extending across many thousands of years.

That continuity was disrupted during the Neolithic transition. Beginning about 8,000 years ago, food-producing populations with distinctly different inner-ear morphologies appeared in the Middle Nile Valley, supporting the conclusion that pastoralism and agriculture arrived with migrating people rather than being adopted solely by the region’s existing foragers.

This was not necessarily a simple or complete replacement. Individuals retaining affinities with the earlier foragers survived for several millennia in areas bordering the Nile Valley, while some remains display combinations of characteristics consistent with limited interaction or admixture between the old and new populations. Samples from the Horn of Africa and Central Africa also showed considerable morphological diversity, indicating population substructure and differing regional demographic histories.

These results independently support earlier research by Martin and many of the same colleagues, which detected a similar Neolithic population discontinuity from the internal structure of ancient teeth. A CNRS account of that earlier study explains how enamel–dentine junctions revealed population replacement and continuing interaction along the Nile and its Saharan margins. Now two independent anatomical systems—teeth and inner ears—have produced compatible reconstructions of the region’s population history.

This presents creationists with the familiar problem of evidence that should not exist if their mythology were true. According to the young-Earth version of the biblical story, the entire human population was reduced to Noah’s family only a little over 4,000 years ago. Every population on Earth must therefore have descended from that tiny group after an extraordinarily rapid dispersal from somewhere in the Middle East.

Refuting Creationism - Rapid Evolution In Andean Potato Eaters

Indigenous Andeans have a digestive superpower; researchers think it may be linked to potatoes  | UCLA

The results of a study co-led by researchers at UCLA and the University at Buffalo, published in Nature Communications in May 2026, provide another straightforward counterexample to the creationist claim that natural processes cannot add genetic material to a genome without the intervention of their particular magic creator. They also show how relatively recent human evolution can be detected, reconstructed and quantified from the DNA of living populations.

What cannot be observed is the intelligently designed caricature of evolution that creationists are conditioned to mistake for the scientific theory: a single dramatic event in which one species suddenly transforms into an unrelated form. There is no plausible biological mechanism for such a transformation, which is why evolutionary biologists have never proposed one. Biological evolution is a change in the frequency of heritable variants within a population over successive generations; larger differences, including those associated with speciation, accumulate through many such changes.

Young-Earth creationists are nevertheless prepared to invoke evolution at an absurdly accelerated rate when their mythology requires it. To squeeze the present diversity of life into the few millennia supposedly available after their genocidal global flood, a small number of vaguely defined ancestral “kinds” would have needed to diversify into hundreds of thousands of beetle species and countless other forms almost overnight. Yet the same creationists baulk at evidence that human populations have undergone much more modest evolutionary changes over thousands of years.

The new research concerns AMY1, the salivary amylase gene. Salivary amylase begins the digestion of starch in the mouth, and people differ considerably in the number of AMY1 copies they carry. An early duplication of the gene occurred in the hominin lineage at least 800,000 years ago, after which repeated duplications, deletions and inversions generated numerous structural variants containing different numbers of copies. These are mutations that change the amount and arrangement of genetic material in the genome — precisely the sort of naturally arising variation that creationists insist cannot occur.

Crucially, cultivating potatoes did not cause the ancestors of Indigenous Andeans to acquire additional AMY1 copies because they needed them. High-copy variants were already present in the population. When potatoes and other starch-rich crops became dietary staples, people carrying more copies probably produced more salivary amylase and obtained a reproductive or survival advantage. Natural selection then increased the frequency of those pre-existing variants — evolution acting as a filter, not as a designer working towards a predetermined goal.

The researchers analysed AMY1 copy numbers in 3,723 people representing 85 populations. Indigenous Peruvian Andeans had among the highest numbers found, with the Quechua participants carrying a median of ten copies, compared with six among the closely related Maya comparison group and seven across the worldwide sample. The genetic evidence indicates that a high-copy haplotype increased in frequency among Andeans from about 2 per cent to approximately 45 per cent after around 10,000 years ago, coinciding with permanent settlement of the high Andes and the domestication of potatoes between about 10,000 and 6,000 years ago.

Refuting Creationism - Ancient Hunters Targeted Female Mammoths - 20,000 Years Before 'Creation Week'

Ancient DNA reveals Ice Age hunter-gatherers preferentially targeted female mammoths - Stockholms universitet

A heap of ancient bones does not come with a label explaining how it was formed. When large accumulations of woolly mammoth remains are found at Upper Palaeolithic sites, archaeologists must determine whether the animals were killed by people, scavenged after natural deaths, or accumulated through entirely natural processes such as floods, landslides or animals becoming trapped in bogs.

Cut marks, deliberately broken bones and stone projectile points embedded in mammoth remains show that humans sometimes hunted and butchered these enormous animals. But such evidence is not present on every bone, leaving open the possibility that some of the great mammoth bonebeds of Eurasia resulted largely from natural mortality rather than sustained human exploitation.

Now an international team led by researchers at the Centre for Palaeogenetics in Stockholm has approached the problem from an ingenious new direction: instead of asking only what happened to the bones, they used ancient DNA to determine whether the mammoths were male or female.

As described in a newly published paper in Current Biology, the researchers analysed genome data from 521 woolly mammoths, Mammuthus primigenius, recovered across Eurasia and North America. These included 448 animals sequenced for the first time, making this one of the largest palaeogenomic studies yet undertaken on an extinct species.

The contrast was striking. Among 421 mammoths recovered as dispersed remains from natural depositional settings, 66 per cent were male and only 34 per cent female. That male bias is consistent with the behaviour of modern elephants: adult males commonly leave their natal herds and live alone, making them more likely to take risks or become caught in natural traps such as bogs, sinkholes and landslides.

However, among 100 mammoths from large bone accumulations associated with Upper Palaeolithic people, the ratio was almost exactly reversed: 70 per cent were female and only 30 per cent male. As the researchers explain, this substantial difference provides population-scale evidence that human activity, rather than natural mortality alone, was the principal force creating these bone accumulations.

That does not necessarily mean that hunters deliberately selected females simply because they were smaller than adult males. If mammoths lived like modern elephants, females and their young would have travelled in matriarchal herds capable of mounting a formidable collective defence. However, such herds may also have followed more predictable routes than solitary males, making them easier for hunter-gatherers to locate repeatedly. People may have hunted them, scavenged animals that died along those routes, or—most probably—used a combination of both strategies.

Either way, the result opens a remarkable window onto human behaviour between about 30,000 and 20,000 years ago. Mammoths supplied meat and fat for food, hides for clothing and shelter, bones for construction, and ivory for tools, ornaments and works of art. By combining genetics with archaeology and knowledge of elephant social behaviour, scientists can now reconstruct something of how Upper Palaeolithic people located and exploited this critically important resource.

And all this human ingenuity, accumulated ecological knowledge and repeated interaction with mammoth herds was taking place tens of thousands of years before creationists believe their god created Earth and everything upon it. Once again, the evidence reveals not a recently created world interrupted by a global flood, but a deep and richly documented human past—one preserved not merely in tools and bones, but in fragments of ancient DNA surviving within those bones.

Creationism Refuted - The Neanderthal Genes We Inherited Are Still Making A Difference.

Neandertal growth hormone receptor increases muscle mass in people today | Max-Planck-Gesellschaft

Evolutionary history is often represented as a neatly branching tree: an ancestral population divides, its descendants diverge, and each resulting lineage continues along its own independent path. Real evolution, however, is frequently much less tidy.

As I explained in my previous post on the Hawaiian honeycreepers, lineages that have begun to diverge can subsequently meet again and exchange genes through hybridisation. The result is reticulated evolution: an evolutionary history that is partly tree-like but also contains connecting branches where genes have passed between related populations.

The same principle applies to our own ancestry.

Modern humans, Neanderthals and Denisovans were not separately created, genetically sealed “kinds”. They were closely related human lineages produced by population separation and divergence, but that separation was never absolute. When populations encountered one another again, they sometimes interbred, allowing genes from one evolutionary branch to enter another—a process known as introgression.

Much of the resulting Neanderthal-derived DNA carried by people today may have little or no detectable effect. Some introgressed variants, however, continue to influence human biology. An international team led by Philipp Kanis of the Max Planck Institute for Evolutionary Anthropology and Hugo Zeberg of Karolinska Institutet has now investigated one particularly interesting example: the Neanderthal version of the growth-hormone receptor.

Their peer-reviewed paper in Current Biology examines two amino-acid substitutions in the receptor that were characteristic of Neanderthals. The growth-hormone receptor sits on the surface of cells and transmits the signal produced when growth hormone binds to it, helping to regulate the growth of bone, muscle and other tissues.

In laboratory-grown cells, the Neanderthal form of the receptor produced a stronger response to growth hormone than the common modern-human version. Under the experimental conditions used, cells carrying it grew by about 40 per cent more, with most of the increase attributable to one of the two Neanderthal-derived substitutions.

Refuting Creationism - The Complex Origins of Modern Humans - No Just A Single Couple - Not Even A Single Species

New technique pinpoints human DNA inherited from ‘ghost’ ancestors - Berkeley News
Using genealogical relationships in DNA, UC Berkeley researchers have uncovered hidden contributions from extinct human populations that left no sequenced genomes.
Meaghan Marohn

The evolutionary ancestry of modern Homo sapiens is far more complex than anything the authors of the Bible’s absurdly simplistic origin myths could have imagined. We already know that populations of our species migrating out of Africa interbred with Neanderthals and Denisovans, and that these two archaic lineages also exchanged genes with one another. Consequently, most people with ancestry outside Africa carry some Neanderthal DNA, while many Asian and especially Oceanian populations also carry Denisovan DNA.

Now, according to a paper just published in Science, our ancestry is even more complicated. A team led by researchers at the University of California, Berkeley, with colleagues at Johns Hopkins University and 54Gene, has identified genetic material inherited from two previously unknown archaic hominin lineages. These are described as “ghost” lineages because no sequenced genome from either population is available: their existence must be inferred from the traces they left in the genomes of living people.

The researchers developed a computational method called TRACE — TRacking Archaic Contributions via ARG Estimation — which reconstructs genealogical relationships among segments of DNA. By identifying regions whose ancestry extends unusually far back in time, TRACE can detect contributions from extinct populations without requiring DNA recovered from their bones.

Creationism Refuted - Humans Were Carving Birds Out Of Mammoth Ivory 30,000 years Before 'Creation Week'

Young Earth creationists insist that Earth—and everything upon it—was created only about 6,000–10,000 years ago, with the entire human population subsequently reduced to eight survivors of a global flood. Unfortunately for that mythology, archaeologists continue to uncover abundant evidence that humans were living, thinking and creating art tens of thousands of years before the supposed “Creation Week”, within cultures whose archaeological remains show no trace of having been interrupted by a planet-drowning flood.

The latest examples are two tiny bird figurines discovered in Hohle Fels Cave in the Swabian Jura of south-western Germany. Carved from mammoth ivory approximately 40,000 years ago, during the Aurignacian period, they were recovered in 2025 from the cave’s well-documented archaeological sequence by a University of Tübingen team led by Professor Nicholas Conard.

Each figurine is scarcely larger than a thumbnail, yet both display remarkable anatomical and behavioural detail. One appears to represent a resting or possibly brooding bird, with its head drawn close to its body and its legs tucked beneath it. The other has its wings spread and its neck extended, perhaps depicting a bird in flight, landing, threatening a rival or displaying during courtship. At just two centimetres long and weighing about 0.7 grams, the latter is the smallest known piece of Ice Age figurative art from the Swabian Jura World Heritage region.

Creationism Refuted - People Were Painting and Drawing On Cave Walls in France Thousands of Years Before 'Creation Week'

First absolute dating of Palaeolithic paintings in the Dordogne | CNRS

For the first time, scientists have obtained direct radiocarbon dates for Palaeolithic paintings in the Grotte de Font-de-Gaume in what is now southwestern France. A black-line drawing of a bison was created between 13,461 and 13,162 calibrated years before present (cal BP), while two parts of a mask-like figure produced dates ranging from about 16,000 to 14,200 cal BP. In other words, people were producing accomplished works of art in France more than 3,000 years before even the upper limit of 10,000 years that young-Earth creationists commonly allow for the entire age of Earth.

Not that this evidence is likely to persuade many creationists to reconsider their beliefs, of course. Once a preferred conclusion has been declared infallible, any evidence that contradicts it can simply be dismissed as fraudulent, mistaken or somehow “wrong”. One stock evasion is the evidence-free suggestion that radioactive decay rates must once have been different. In the case of radiocarbon dating, even known variations in atmospheric carbon-14 are measured and incorporated into the calibration curves. But no amount of calibration can correct a chronology that is wrong by design.

For anyone more interested in discovering the truth than in finding excuses to protect a preordained conclusion, however, these paintings are fascinating glimpses into how members of our species perceived the world around them, with its bison, horses, cave lions, mammoths and other Ice Age animals. Having visited the Grotte du Pech Merle in the Lot and the Lascaux II faithful reproduction of the famous Lascaux cave in the Dordogne, I can testify to the breathtaking magnificence of these monumental works.

Their purpose can only be surmised. They may have formed part of rituals intended to influence or appropriate the power of the animals; they may have recorded stories, conveyed knowledge or helped to instruct younger members of the group. None of these interpretations can yet be demonstrated conclusively. A controversial paper published in 1998 compared certain features of Upper Palaeolithic cave art with drawings made by a young autistic child with exceptional artistic ability. It did not, however, establish that any particular Palaeolithic artist was autistic.

During my visit to Pech Merle, our guide suggested that one of the great animal friezes might have been drawn in a matter of hours by a single artist, using bold, confident lines in black pigment. That interpretation may remain speculative, but the powers of observation, memory and control evident in those sweeping lines are unmistakable.

The new dating study was carried out on paintings in the Grotte de Font-de-Gaume, near Les Eyzies in the Dordogne, by an interdisciplinary research team led by CNRS researcher Ina Reiche. Direct radiocarbon dating had previously been considered impossible because the black pigments used at Font-de-Gaume, Lascaux and other decorated caves in the region were assumed to consist solely of iron and manganese oxides, which contain no carbon. However, the absence of carbon had never actually been demonstrated.

Using non-invasive Raman microspectrometry and hyperspectral imaging, the researchers examined black-line drawings of a bison and a figure interpreted as a human or animal face, or “mask”. These techniques revealed that charcoal was distributed uniformly throughout the black lines, rather than occurring only in isolated patches, helping to rule out contamination from graffiti or tourist activity.

New DNA Study Unlocks Origins, Social Structure of Neolithic Shimao Civilization----Chinese Academy of Sciences

In my last blog post, I pointed out that ancient Egypt’s archaeological and written record extends continuously from long before the date young-Earth creationists assign to Noah’s Flood, through that supposed catastrophe and into biblical times. Nowhere is there any sign that Egypt was destroyed by a global flood and subsequently repopulated by migrants from Mesopotamia. I also showed that the biblical writers who set stories in Egypt possessed only a tenuous understanding of its real history and culture.

Ancient China presents creationists with much the same problem. Its archaeological record contains long regional sequences extending across the supposed date of the Flood, with local populations, cultures and economies continuing to develop. If every human outside Noah’s immediate family had been exterminated, the existing peoples of East Asia should disappear from the record and be replaced by a rapidly expanding population of recent Mesopotamian origin. That is not what archaeology shows—and ancient DNA now provides an especially clear test of the claim.

The evidence comes from a paper published in Nature in November 2025 by an international team led by Professor Qiaomei Fu of the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) at the Chinese Academy of Sciences, working with researchers from several other Chinese institutions.

The team analysed genome-wide data from 169 ancient individuals recovered from Shimao and surrounding settlements in northern China. Population analyses were conducted using 144 unrelated individuals, while the remaining close relatives enabled the researchers to reconstruct pedigrees extending across as many as four generations.

Shimao, in northern Shaanxi Province, was one of the largest fortified settlements in Late Neolithic China. Occupied from approximately 2300 to 1800 BCE, it covered about four square kilometres and contained massive stone walls, separate inner and outer enclosures, specialised craft production, elite cemeteries and unmistakable evidence of a highly stratified society. Its occupation therefore began at about the very time when, according to the conventional young-Earth creationist chronology, the world should have been struggling to recover from a global extermination and repopulation by Noah’s immediate descendants.

Instead, the genomes showed that the people associated with Shimao were predominantly descended from populations already living in northern Shaanxi at least 1,000 years earlier. Those earlier inhabitants were associated with the Yangshao cultural tradition of the Yellow River’s Loess Plateau. The researchers found regional genetic continuity from the Middle to the Late Neolithic—continuity extending from before the supposed Flood into the centuries following it.

This was not a completely isolated or genetically static population. The researchers detected continuing contact with Yumin-related people from Inner Mongolia, close connections with the contemporary Taosi population farther south, and some ancestry from southern East Asian populations, possibly associated with the northward spread of rice cultivation. These were the ordinary movements, exchanges and intermarriages expected among neighbouring prehistoric farming and pastoral communities. They did not interrupt the dominant local ancestry, and there was no sign of wholesale population replacement by descendants of a family recently arrived from Mesopotamia.

The genetic evidence also revealed much about the organisation of Shimao society. Pedigrees reconstructed from elite burials indicated a predominantly patrilineal system in which status and wealth commonly passed from high-ranking men to their sons. Male members of these lineages showed relatively little diversity in their Y-chromosome ancestry, whereas the women displayed much greater mitochondrial diversity. This is consistent with women frequently marrying into communities dominated by established male lineages, although the evidence for strictly patrilocal residence remains suggestive rather than conclusive.

The study also uncovered a possible sex-related pattern in Shimao’s practice of human sacrifice. Nine of the ten sampled victims buried beneath the East Gate were male, contradicting earlier identifications based on skeletal anatomy. In contrast, most sampled sacrificial victims accompanying elite burials were female: six of seven at Hanjiagedan and fourteen of nineteen at Huangchengtai. This suggests that male and female victims may have been selected for different rituals conducted in different places, although the researchers caution that the number of genetically sexed victims remains too small to establish the pattern conclusively.

We Can Tell The Bible Was Written By Ignorant People - Not Just By What's In It, But By What Isn't

One of the clearest indications that the Bible was written by people with a severely limited knowledge of the world is, in addition to the factual errors in it, such as Earth being flat with a dome over it, there is the evidence of what is not in it. Its authors wrote as though the small part of the ancient Near East familiar to them was effectively the whole inhabited Earth, so there is nothing in the Bible from outside a small area around the Middle East. They had no conception of a southern hemisphere, knew nothing of continents such as South America, and had no awareness of the peoples, cultures and complex histories that had existed there for thousands of years.

That parochial view of the world is exposed every time archaeologists and palaeoecologists reconstruct the history of regions the Bible’s authors did not even know existed. Far from being a divinely inspired account of the whole planet, the Bible reflects the geographical horizons and cultural assumptions of the scientifically illiterate people who composed it.

The latest example comes from the cold highlands of southern Brazil, where an international team of researchers has reconstructed how climate, fire and Indigenous land management shaped the distinctive mosaic of Araucaria forest and campos grassland during the past 6,000 years. The research is described by Oliver J. Wilson, a lecturer in the School of Natural Sciences at the University of Lincoln, in an article in The Conversation and was published in Scientific Reports.

The researchers combined several independent sources of evidence: pollen and microscopic charcoal preserved in continuously accumulating bog sediments, radiocarbon-dated archaeological evidence, a rainfall record preserved in a cave speleothem, and ecological models showing how the forest should have responded to climatic change. Together, these sources reveal a detailed history of gradual climatic shifts, changing fire regimes, forest expansion and human modification of the landscape.

Refuting Creationism - Population Collapse And Migration in Neolithic Europe - And No Evidence Of A Genocidal Flood


The researchers have conducted DNA analyses of the skeletons from a burial site like this one in France and found traces of several different diseases.

A paper published in Nature Ecology & Evolution by a large international team led by researchers at the University of Copenhagen, reports evidence that simply should not exist if the Bible creation myth, and its later global genocidal flood myth, had any basis in reality. The evidence shows a significant population collapse among Neolithic farming communities in what is now northern France about 5,000 years ago, followed by migration into the depopulated area by people with strong genetic links to southern France and the Iberian Peninsula.

The study is based on ancient DNA from 132 individuals buried in the allée sépulcrale at Bury, a large megalithic tomb about 50 kilometres north of Paris. The site was used during two distinct burial phases, separated by a hiatus associated with the wider Neolithic decline around 3000 BC. The researchers found that the people buried before and after this decline were not simply later descendants of the same local population, but belonged to largely discontinuous genetic groups. In other words, this was not merely a change in burial custom; it was a major population turnover.

The problems this presents for creationism are multiple. First, there is the evidence of established farming populations in northern Europe at a time when, according to Young Earth Creationist chronology, the world had only recently been magicked into existence. Secondly, there is the embarrassing survival of archaeological and genetic evidence which, under the same mythology, should either have been destroyed in a global flood a few centuries later, or buried beneath a distinctive, worldwide layer of fossil-bearing flood silt — a layer which is conspicuous by its absence. Thirdly, there is the evidence that the human population of Europe had already diversified into regionally distinct genetic populations by about 3000 BC, with enough structure for ancient DNA to distinguish northern French and German-like Neolithic farmers from later migrants with strong southern French and Iberian affinities.

None of this, of course, will cause creationists to reconsider the mythology. We can confidently predict that it will instead be treated as another test of faith: one more opportunity to demonstrate the strength of their determination never to let evidence change their minds. In creationist apologetics, refusal to learn is often mistaken for intellectual victory. The more compelling the evidence, the greater the achievement in ignoring it.

The reason for the population decline is not yet clear. The human remains contained genetic traces of pathogens, including the plague bacterium, Yersinia pestis, and the louse-borne relapsing fever bacterium, Borrelia recurrentis, but the evidence does not support plague as the sole cause of the collapse. The more likely explanation is a combination of disease, environmental stress, demographic disruption and social breakdown. Earlier burials contained multiple generations from the same extended families, suggesting stable, kin-based communities. Later burials were more selective and were dominated by a single male lineage, indicating a marked change in social organisation after the population turnover.

This adds to the growing picture of the so-called Neolithic decline as a widespread phenomenon affecting much of northern and western Europe, not just Scandinavia and northern Germany. It also offers a plausible explanation for the abrupt disappearance of megalithic tomb-building and other monumental traditions across parts of Europe at about the same time. The people who built those monuments did not merely change their minds about architecture; in places such as the Paris Basin, the population itself appears to have collapsed and been replaced.
