2026 is shaping up to be yet another dreadful year for the creationist cult, as palaeontology, archaeology, geochronology, and genetics continue to uncover facts that do not merely show creationism to be a divinely inspired allegory or metaphor, but demonstrate that it is simply and unequivocally wrong at every level.

At times it seems like an unfair contest between myths invented by Bronze Age pastoralists—without the slightest benefit of scientific understanding—and the cumulative output of modern science. It is rather like a chess match between a pigeon and a powerful computer, in which the pigeon’s concept of chess is to knock the pieces over, then strut about on the board declaring victory. This tactic is known in creationist circles as “debate”, and everywhere else as “pigeon chess”.

As usual, the closing months of the year have brought yet more palaeontological evidence that creationism cannot accommodate. This latest find dates to around 37 million years before creationists believe Earth was magicked into existence, bears the unmistakable fingerprints of one of those supposedly “non-existent” transitional forms, and displays the familiar mosaic of archaic and modern features that are commonplace in the fossil record. It also fits precisely into the established timeline of reptilian evolution and was discovered in southern England, in deposits that align exactly with the known geological and climatological history of the region.

The fossil was discovered in 1981 at Hordle Cliff, England, and donated to the Natural History Museum in London, where it has now been identified as a new species. The identification was made by Professor Georgios L. Georgalis of the Institute of Systematics and Evolution of Animals at the Polish Academy of Sciences in Kraków, currently a visiting researcher at the Natural History Museum. His paper, co-authored with Dr Marc E. H. Jones, curator of fossil reptiles and amphibians, has recently been published open access in Comptes Rendus Palevol.

Hordle Cliff, Geology. Hordle Cliff is one of the most important and intensively studied fossil-bearing coastal exposures in southern England. Its significance lies in the exceptional sequence of Eocene marine sediments exposed by continual coastal erosion along the western Solent.



Geological setting

Hordle Cliff lies on the coast of Hampshire, west of Milford-on-Sea, forming part of the Hampshire Basin, a large sedimentary basin that accumulated marine and marginal-marine deposits during the early Cenozoic. The strata exposed here date mainly to the Late Eocene, approximately 41–34 million years ago, a time when southern England lay beneath a warm, shallow sea.

Stratigraphy

The cliff exposes a classic succession of Eocene formations, including:
  • Barton Group (upper Eocene)
    • Dominated by clays, silts, and fine sands
    • Deposited in shallow marine conditions
    • Exceptionally fossil-rich
  • Barton Clay Formation
    • The most famous unit at Hordle Cliff
    • Known for abundant molluscs, sharks’ teeth, rays, fish remains, turtles, crocodilians, birds, and reptiles (including snakes)
    • Indicates warm, subtropical seas with nearby coastal and estuarine environments

These sediments accumulated gradually, layer upon layer, in calm marine settings—exactly the opposite of the chaotic, high-energy deposition required by flood-geology models.



Depositional environment

During the Late Eocene, this region experienced:
  • **Warm greenhouse climates
  • High sea levels
  • Low-energy marine sedimentation

Fine-grained clays settled slowly out of suspension, allowing delicate fossils to be preserved intact. Many beds show bioturbation, shell beds, and orderly fossil assemblages—clear evidence of stable ecosystems persisting over long periods.



Fossil significance

Hordle Cliff is internationally important because it preserves:
  • Highly diverse faunas spanning multiple ecological niches
  • Mosaic evolutionary forms, including transitional reptiles
  • Fossils preserved in situ, not reworked or mixed from different ages

This makes the site particularly valuable for reconstructing Eocene ecosystems and tracing evolutionary change through time.



Structural and erosional features

The cliffs themselves are relatively soft and unstable:
  • Frequent slumping and landslips continually expose fresh material
  • Ongoing erosion has made Hordle Cliff productive for over two centuries
  • The geology is simple and undisturbed, with gently dipping strata—no folding, overturning, or tectonic chaos



Why this matters for creationist claims

The geology of Hordle Cliff presents multiple, independent problems for young-Earth creationism:
  • The sediments record millions of years of gradual deposition
  • Fossils are ordered, local, and ecological, not globally mixed
  • Climatic signals match global Eocene warming trends
  • The strata fit seamlessly into the wider regional and global geological record

There is no evidence whatsoever of rapid, catastrophic deposition, let alone a single global flood. Instead, Hordle Cliff is a textbook example of slow geological processes operating exactly as modern geology predicts.
The discovery and its broader significance were explained in a recent Natural History Museum news item by James Ashworth.
“Weird” new species of ancient fossil snake discovered in southern England
An extinct snake has slithered its way out of obscurity over four decades after its discovery.

The newly described species of reptile, Paradoxophidion richardoweni, is offering new clues in the search for the origin of ‘advanced’ snakes.

In 1981, the backbones of an ancient snake were uncovered at Hordle Cliff on England’s south coast. They’ve now been revealed as the remnants of a previously unknown species.

Research published in the journal Comptes Rendus Palevol has identified that the vertebrae belong to a new species named Paradoxophidion richardoweni. This animal would have lived around 37 million years ago, when England was home to a much wider range of snakes than it is now.

While little is known about this animal’s life, it could shed light on the early evolution of biggest group of modern snakes. This is because Paradoxophidion represents an early-branching member of the caenophidians, the group containing the vast majority of living snakes.

The new species is so early in the evolution of the caenophidians that it has a peculiar mix of characteristics now found in different snakes throughout this group. This mosaic of features is summed up in its genus name, with Paradoxophidion meaning ‘paradox snake’ in Greek.

Its species name, meanwhile, honours Sir Richard Owen. Not only did he name the first fossil snakes found at Hordle Cliff, but this scientist was also instrumental in establishing what’s now the Natural History Museum where the fossils are cared for, giving the name multiple layers of meaning.

Lead author Dr Georgios Georgalis, from the Institute of Systematics and Evolution of Animals of the Polish Academy of Sciences in Krakow, says that being able to describe a new species from our collections was ‘a dream come true’.

It was my childhood dream to be able to visit the Natural History Museum, let alone do research there, so, when I saw these very weird vertebrae in the collection and knew that they were something new, it was a fantastic feeling. It’s especially exciting to have described an early diverging caenophidian snake, as there’s not that much evidence about how they emerged. Paradoxophidion brings us closer to understanding how this happened.

What’s been discovered at Hordle Cliff?

Hordle Cliff, near Christchurch on England’s south coast, provides a window into a period of Earth’s history known as the Eocene that lasted from around 56 to 34 million years ago.

Dr Marc Jones, our curator of fossil reptiles and amphibians who co-authored the research, says that this epoch saw dramatic climatic changes around the world.

Around 37 million years ago, England was much warmer than it is now, though the Sun was very slightly dimmer, levels of atmospheric carbon dioxide were much higher. England was also slightly closer to the equator, meaning that it received more heat from the Sun year round.

Fossils were first uncovered at Hordle Cliff around 200 years ago. In the early 1800s Barbara Rawdon-Hastings, the fossil-hunting Marchioness of Hastings, collected the skulls of crocodile relatives from the site, one of which Richard Owen would later name after her.

Since then, a variety of fossil turtles, lizards and mammals have also been uncovered at Hordle Cliff. There are also abundant snake fossils, including some particularly important species.

The fossil snakes found at Hordle Cliff were some of the first to be recognised when Richard Owen studied them in the mid-nineteenth century. They include Paleryx, the first named constrictor snake in the fossil record. Smaller snakes from this site, however, haven’t been as well investigated. Paradoxophidion’s vertebrae are just a few millimetres long, so historically they’ve not had a lot of attention.

Dr Georgios Georgalis.

To get a better look at these fossils, Marc and Georgios took CT scans of the bones. In total, they identified 31 vertebrae from different parts of the spine of Paradoxophidion.

We used these CT scans to make three dimensional models of the fossils. These provide a digital record of the specimen which we’ve shared online so that they can be studied by anyone, not just people who can come to the museum and use our microscopes.

Dr Marc E.H. Jones.

The scans show that the fossils are all slightly different shapes and sizes, as the snake’s spine bones gradually taper from head to tail. However, they share some features that show they all belong to one species.

Georgios estimates that Paradoxophidion would have been less than a metre long, but other details about this animal’s life are hard to say. The lack of a skull makes it difficult to know what it ate, while the vertebrae don’t have any sign of being adapted for a specialised lifestyle, such as burrowing.

The backbones of Paradoxophidion are surprisingly similar to those of Acrochordus snakes.

A living link to the past?

Though the vertebrae don’t give much away about Paradoxophidion’s lifestyle, they are strikingly similar to a group of snakes known as the Acrochordids. These reptiles are known as elephant trunk snakes due to their unusually baggy skin.

Today, only a few species of these snakes can be found living in southeast Asia and northern Australia. But they’re among the earliest branches of the caenophidian family tree, with a fossil record extending back over 20 million years.

As Paradoxophidion is really similar to the acrochordids, it’s possible that this snake could be the oldest known member of this family. If it was, then it could mean that it was an aquatic species, as all Acrochordids are aquatic. On the other hand, it might belong to a completely different group of caenophidians. There’s just not enough evidence at the moment to prove how this snake might have lived, or which family it belongs to.

Dr Georgios Georgalis.

Finding out more about Paradoxophidion and the early evolution of the caenophidians means that more fossils will need to be studied. Georgios hopes to continue his work in our fossil reptile collections in the near future, where he believes more new species might be waiting.

I’m planning to study a variety of snake fossils in the collection, including those originally studied by Richard Owen. These include the remains of the giant aquatic snake Palaeophis, which were first found in England in the nineteenth century. There are also several bones with differing morphology that haven’t been investigated before that I’m interested in looking at. These might represent new taxa and offer additional clues about snake evolution.

Dr Georgios Georgalis.

Publication:


Taken together, the geology of Hordle Cliff leaves no room for creationist evasions. The sediments accumulated slowly in warm, shallow Eocene seas, preserving stable marine ecosystems over millions of years. The fossils are local, ordered, and ecologically coherent, embedded within undisturbed strata that fit seamlessly into the wider geological history of southern England and the global Eocene record. None of this resembles the chaotic aftermath of a recent global catastrophe; all of it is exactly what conventional geology predicts.

The newly identified fossil from this site simply adds to the embarrassment. It is neither out of place nor out of time, but sits precisely where evolutionary theory says it should—both stratigraphically and anatomically—displaying the familiar mosaic of ancestral and derived features that creationists insist do not exist. Hordle Cliff has been yielding such transitional forms for over two centuries, and every one of them tells the same story.

For creationism, this presents a recurring and insoluble problem. Each new discovery must be dismissed, distorted, or ignored, not because it is anomalous, but because it fits too well. Hordle Cliff is not an exception to the rule; it is the rule itself—one more quietly devastating reminder that the natural world records its own history with remarkable consistency, and that history bears no resemblance whatsoever to a Bronze Age flood myth.

As Anticipated In My Novels - Wolves Lived With Humans 3,000-5,000 Years Ago

Ancient wolves on remote Baltic Sea island reveal link to prehistoric humans - Stockholms universitet

This article struck a chord with me — not primarily because it refutes creationism, although it certainly does that by presenting evidence that simply should not exist if the biblical flood genocide story contained even a kernel of truth. Such evidence ought either to have been swept away entirely or buried beneath a thick layer of flood-deposited silt containing a chaotic jumble of animal and plant fossils from unrelated landmasses. It was neither.

What resonated more personally, however, is that I have just published a novel in which a clan of Neolithic hunter-gatherers forms a close association with wolves, with the animals playing a central role in both their hunting strategies and their folklore. In the novel, The Way of the Wolf: A Stone Age Epic — the second volume in the Ice Age Tales series — Almora is raised alongside a wolf cub that becomes her inseparable guide and protector. This relationship gives rise to several versions of a mythologised hunt in which the wolf, Sharma, saves the day and defends the hunters. Together with her Neanderthal partner, Tanu, Almora later leads a group of exiles who encounter a clan already familiar with these legends, and who have begun adopting abandoned wolf cubs and raising them as part of the community.

It is fiction, of course — but a deliberately realistic depiction of how wolves could have been domesticated through mutual benefit, cooperation, and prolonged social contact with humans.

The article itself concerns the discovery by researchers at the Francis Crick Institute, Stockholm University, the University of Aberdeen, and the University of East Anglia of wolf remains on a remote Baltic island that could only have been transported there by boat. Isotopic analysis shows that these wolves consumed the same food as the humans, and skeletal pathology in one individual indicates long-term care. The findings are reported in a research paper published in Proceedings of the National Academy of Sciences (PNAS).

Unintelligent Design - The Design Blunder That Causes Cancer - Or Was It Malevolent Design?


Graphical abstract

Scientists find cancer weak spot in backup DNA repair system | Scripps Research

Scientists at the Scripps Institute have discovered a defective DNA repair mechanism that would normally trigger cell death but which, paradoxically, keeps cancer cells alive. They have recently published their findings, open access, in Cell Reports. It is exactly the sort of biochemical complexity that creationists routinely mistake for evidence of intelligent design, having been led to believe that well-designed systems must be highly complex. In reality, good intelligent design is minimally complex: complexity increases the risk of failure, is harder to maintain, and is more energetically costly.

The DNA “code” is one of creationism’s favourite props for its familiar ignorance-plus-incredulity-therefore-God-did-it argument — a textbook god-of-the-gaps false dichotomy. Yet even a superficial look beneath the metaphor reveals that DNA replication and repair are very far from the flawless perfection we would expect from an omniscient, omnipotent and omnibenevolent deity — especially when it comes to its supposedly special creation, humankind. What we actually observe is a fragile, error-prone system patched together by evolutionary history rather than foresight.

The system is only needed in the first place because cell replication in multicellular organisms remains essentially identical to that of single-celled organisms. Despite the fact that the benefits of multicellularity arise from cell specialisation into tissues and organs with discrete functions — each requiring only a tiny fraction of the genome — every cell is forced to copy the entire DNA complement every time it divides. This vast waste of energy and resources serves only to multiply the probability of error, and errors are not rare anomalies but routine occurrences. This is not the signature of intelligent design.

The Scripps Institute team have shown that some cancer cells survive precisely because the normal high-fidelity repair system fails. When that happens, a crude backup mechanism takes over — an emergency repair process that is little more than a biological kludge and which introduces further errors as it works. It is rather like calling out an emergency plumber who fixes one leak by installing a long section of pipe riddled with smaller leaks. Would anyone describe that as intelligent workmanship?

Creationism Refuted - A Rich Collection of Dinosaur Fossils from 72 Million Years Before 'Creation Week'


The ancient environment and its fauna.

Reconstruction by Tibor Pecsics
Paleontoligists have discovered an exceptionally rich dinosaur site in Transylvania.

Normally, creationists seize on any concentration of animal fossils that can be attributed to flooding as supposed “evidence” for their favourite Bronze Age myth of a global genocide. On that basis, they should be delighted by recent news from Romania describing a rich deposit of dinosaur fossils that appears to have accumulated as a result of flooding in the Hațeg Basin.

There is, however, a serious snag. These fossils occur in deposits dated to around 72 million years ago — tens of millions of years before creationists believe the Earth even existed — and the evidence points clearly to repeated local flooding events, not a single global catastrophe.

The discovery of the fossil site is reported in the journal PLOS ONE by the Valiora Dinosaur Research Group, a collaboration of Hungarian and Romanian palaeontologists co-led by Gábor Botfalvai and Zoltán Csiki-Sava of the Institute of Geography and Earth Sciences, Department of Palaeontology, ELTE Eötvös Loránd University, Budapest, Hungary.

Creationism Refuted - Highly Accurate Dating of Dinosaur Eggs

Dinosaur eggshells unlock a new way to tell time in the fossil record | Stellenbosch University

This paper will have creationists searching for reasons to dismiss evidence that would, if they were prepared to accept it honestly, force them to concede that their beliefs are wrong. It reports a discovery by researchers at Stellenbosch University showing that dinosaur eggshells can be dated with a high degree of precision using an already well-established technique: uranium–lead (U–Pb) radiometric dating.

Until now, U–Pb dating has been most famously applied to zircon crystals in volcanic ash, where the age can be determined by measuring the ratio of radioactive uranium isotopes to the stable lead isotopes produced by their decay. In this study, however, the same underlying principles are applied to calcite crystals preserved in dinosaur eggshells.

The scientists have published their method, open access, in the journal Communications Earth & Environment.

Unintelligent Design - The Irreducibly Complex Cause Of Alzheimers - Malevolent Design or Evolution?


Clues to Alzheimer’s disease may be hiding in our ‘junk’ DNA

Researchers from the University of New South Wales (UNSW), Sydney, Australia, have identified DNA switches that help control how astrocytes work. These are brain cells that support neurons and are known to play a role in Alzheimer’s disease. They have just published their findings in Nature Neuroscience.

Coming soon after researchers at Aarhus University in Denmark discovered a design defect in astrocytes that contributes to the development of Alzheimer’s, this represents a double embarrassment for those creationists who understand its implications.

Firstly, there is the embarrassment that the cause of Alzheimer’s is indistinguishable from Michael J. Behe’s favourite ‘proof’ of intelligent design — irreducible complexity — in that all the elements must be present for Alzheimer’s to occur.

Secondly, there is the discovery by the Australian team of which triggers ‘switch on’ which genes that affect the astrocytes implicated in Alzheimer’s. These switches are embedded in the 98% of the human genome that is non-coding, or so-called ‘junk’ DNA. Since they can be separated from the genes they regulate by thousands of base pairs, it has been notoriously difficult to identify which switches control which genes. Now, using CRISPR, the team have identified around 150 of these regulatory elements.

The existence of this non-coding DNA has long been an embarrassment for creationists, who have been unable to explain why an intelligent designer would produce so much DNA that does not contain the roughly 20,000 genes that actually code for proteins. Why such prolific waste, adding massively to the risk of errors that can result in cancer?

The creationist response has been to conflate the terms ‘non-coding’ and ‘non-functional’, and then proclaim this ‘functional DNA’ as intelligently designed — reducing, but by no means eliminating, the amount of ‘junk’ they still have to explain away. Of course, ‘non-coding’ does not mean ‘not transcribed’, only that the RNA does not code for a functional protein. However, this non-coding but functional DNA does play a role in gene expression, in that the resulting RNA can act as controls or ‘switches’ that turn genes on and off.

So, creationists — having triumphantly waved ‘functional, non-coding DNA’ as evidence for intelligent design after all — are now presented with the fact that it is part of the ‘irreducible’ cause of Alzheimer’s, and probably the cause of many other diseases with a genetic basis.

Creationism Refuted - A Massive Evolutionary Arms Race 130 Million Years Before 'Creation Week'

Apex predators in prehistoric Colombian oceans would have snacked on killer whales today: McGill study | Newsroom - McGill University

Two researchers at McGill University, Montréal, Québec, Canada, have uncovered evidence of an ecosystem teeming with giant marine predators some 130 million years ago. The largest of these predators could, quite literally, have eaten something the size of a modern orca as little more than a snack. This will make depressing reading for creationists, not only because it all happened deep in the long pre-“Creation Week” history of life on Earth, but because the evolutionary arms races that led to these giants are precisely what the theory of evolution by natural selection predicts.

The two researchers, Dirley Cortés and Professor Hans C. E. Larsson, have just published their findings, open access, in the Zoological Journal of the Linnean Society.

It doesn’t get any easier for creationists. Just because it’s Christmas week doesn’t mean the awkward facts are going to go away, or that scientists are going to stop uncovering more of them. No matter what they post on social media; no matter how loudly they shout; or how fervently they gather on Sundays to collectively drown out their doubts, Santa is not going to deliver evidence that the Bronze Age creation myths in the Bible contain even a grain of historical truth. The problem is that truth remains true whether a creationist believes it or not, and regardless of whether their parents believed it. No amount of looking the other way or pretending the facts aren’t there will ever change that.

The palaeontologists reached their conclusions by reconstructing an ecosystem network for all known animal fossils from the Paja Formation in central Colombia. They used body sizes, feeding adaptations, and comparisons with modern animals, and then validated the results against one of the most detailed present-day marine ecosystem networks available: the living Caribbean ecosystem, which they used as a reference. The Paja ecosystem thrived with plesiosaurs, ichthyosaurs, and abundant invertebrates, giving rise to one of the most intricate marine food webs known. This complexity emerged as sea levels rose and Earth’s climate warmed during the Mesozoic era, including the Cretaceous, triggering an explosion of marine biodiversity.

How We Know The Bible is Wrong - Human Artifacts That Would't Exist If The Bible Was Real History


World’s Earliest Botanical Art Discovered By HUJI Archeologists, and Evidence of Prehistoric Mathematical Thinking - The Canadian Friends of Hebrew University
Geometric and mathematical patterns on Halafian pottery.

Scientists have once again — almost certainly unintentionally — produced evidence that the Bible is profoundly wrong about human history. This time it comes in the form of pottery shards dating back more than 8,000 years to the Halafian culture of northern Mesopotamia (c. 6200–5500 BCE). These artefacts show that people were not only producing sophisticated ceramics, but were decorating them with complex mathematical patterns long before the formal invention of numbers and counting systems.

The findings of the archaeologists, Professor Yosef Garfinkel and Sarah Krulwich of the Hebrew University of Jerusalem, are published, open access, in the Journal of World Prehistory.

According to the biblical account of global history, Earth was subjected to a catastrophic genocidal reset, inflicted in a fit of pique by a vengeful god who had failed to anticipate how his creation would turn out. Rather than simply eliminating humanity and starting again with a corrected design, this deity allegedly chose to preserve the same flawed model in a wooden boat while drowning everything else beneath a flood so deep it covered the highest mountains. The implicit hope appears to have been that repeating the experiment would somehow yield a different result.

As implausible as that story already is, we now possess a vast body of archaeological and palaeontological evidence showing not only that Earth is vastly older than the biblical narrative allows, but that this supposed catastrophic reset never occurred. The latter is demonstrated by the existence of civilisations that predate the alleged flood and continue uninterrupted through it, as though it never happened at all. Their material remains include artefacts that would have been completely destroyed or displaced by such a deluge, and settlement sites that show no sign of burial beneath a chaotic, fossil-bearing sedimentary layer containing mixed local and foreign species.

No such global layer exists. Instead, human artefacts are found precisely where they were made and used, unaffected by any mythical torrent scouring the planet clean.

The designs on the Halafian pottery themselves are particularly revealing. They include repeating patterns — for example, binary progressions such as 2, 4, 8, 16, 32 — suggesting that this culture possessed systematic ways of dividing land or goods to ensure equitable distribution.

A new fossil face sheds light on early migrations of ancient human ancestor | EurekAlert!

Palaeontologists at the College of Graduate Studies, Glendale Campus of Midwestern University in Arizona, have reconstructed the head and face of an early Homo erectus specimen, DAN5, from Gona in the Afar region of Ethiopia on the Horn of Africa. In doing so, they have uncovered several unexpected features that should trouble any creationist who understands their significance. The research has just been published open access in Nature Communications.

Creationism requires its adherents to imagine that there are no intermediate fossils showing a transition from the common Homo/Pan ancestor to modern Homo sapiens, whom they claim were created as a single couple just a few thousand years ago with a flawless genome designed by an omniscient, omnipotent creator. The descendants of such a couple would, of course, show no genetic variation, because both the perfect genome and its replication machinery would operate flawlessly. No gene variants could ever arise.

The reality, however, is very different. Not only are there vast numbers of fossils documenting a continuum from the common Homo/Pan ancestor of around six million years ago, but there is also so much variation among them that it has become increasingly difficult to force them into a simple, linear sequence. Instead, human evolution is beginning to resemble a tangled bush rather than a neat progression.

The newly reconstructed face of the Ethiopian Homo erectus is no exception. It displays a mosaic of more primitive facial traits alongside features characteristic of the H. erectus populations believed to have spread out of Africa in the first of several waves of hominin migration into Eurasia. The most plausible explanation is that the Ethiopian population descended from an earlier expansion within Africa, became isolated in the Afar region, and retained its primitive characteristics while other populations continued to evolve towards the more derived Eurasian form.

The broader picture that has emerged in recent years—particularly since it became clear that H. sapiens, Neanderthals, and Denisovans formed an interbreeding complex that contributed to modern non-African humans—is one of repeated expansion into new environments, evolution in isolation, and subsequent genetic remixing as populations came back into contact. DAN5 represents just one of these populations, which appears to have evolved in isolation for some 300,000 years.

Not only is this timescale utterly incompatible with the idea of the special creation of H. sapiens 6,000–10,000 years ago, but the sheer existence of this degree of variation is also irreconcilable with the notion of a flawless, designed human genome. Even allowing for old-earth creationist claims that a biblical “day” may represent an elastic number of millions of years, the problem remains: a highly variable genome must still be explained as the product of perfect design. A flawless genome created by an omniscient, omnipotent creator should, moreover, have been robust enough to withstand interference following “the Fall” — an event such a creator would necessarily have foreseen, particularly if it also created the conditions for that fall and the other creative agency involved (Isaiah 45:7).

As usual, creationists seem to prefer the conclusion that their supposed intelligent creator was incompetent—either unaware of the future, indifferent to it, or powerless to prevent it—rather than accept the far more parsimonious explanation: that modern Homo sapiens are the product of a long, complex evolutionary history from more primitive beginnings, in which no divine intervention is required.

Origins of Homo erectus
Homo erectus
Homo erectus appears in the fossil record around 1.9–2.0 million years ago, emerging from earlier African Homo populations, most likely derived from Homo habilis–like ancestors. Many researchers distinguish early African forms as Homo ergaster, reserving H. erectus sensu stricto for later Asian populations, although this is a taxonomic preference rather than a settled fact.

Key features of early H. erectus include:
  • A substantial increase in brain size (typically 600–900 cm³ initially, later exceeding 1,000 cm³)
  • A long, low cranial vault with pronounced brow ridges
  • A modern human–like body plan, with long legs and shorter arms
  • Clear association with Acheulean stone tools and likely habitual fire use (by ~1 million years ago)

Crucially, H. erectus was the first hominin to disperse widely beyond Africa, reaching:
  • The Caucasus (Dmanisi) by ~1.8 Ma
  • Southeast Asia (Java) by ~1.6 Ma
  • China (Zhoukoudian) by ~0.8–0.7 Ma

This makes H. erectus not a single, static species, but a long-lived, geographically structured lineage.



Homo erectus as a population complex

Rather than a uniform species, H. erectus is best understood as a metapopulation:
  • African populations
  • Western Eurasian populations
  • East and Southeast Asian populations

These groups experienced repeated range expansions, isolation, local adaptation, and partial gene flow, producing the mosaic anatomy seen in fossils such as DAN5.

This population structure is critical for understanding later human evolution.



Relationship to later Homo species
Neanderthal (H. neanderthalensis)
From H. erectus to H. heidelbergensis

By around 700–600 thousand years ago, some H. erectus-derived populations—probably in Africa—had evolved into forms often grouped as Homo heidelbergensis (or H. rhodesiensis for African material).

These hominins had:
  • Larger brains (1,100–1,300 cm³)
  • Reduced facial prognathism
  • Continued Acheulean and early Middle Stone Age technologies

They represent a transitional grade, not a sharp speciation event.



Divergence of Neanderthals, Denisovans, and modern humans

Genetic and fossil evidence indicates the following broad pattern:
  • ~550–600 ka: A heidelbergensis-like population splits
    • African branch → modern Homo sapiens
    • Eurasian branch → Neanderthals and Denisovans

Neanderthals
  • Evolved primarily in western Eurasia
  • Adapted to cold climates
  • Distinctive cranial morphology
  • Contributed ~1–2% of DNA to all non-African modern humans

Denisovans
  • Known mostly from genetic data, with sparse fossils (Denisova Cave)
  • Closely related to Neanderthals but genetically distinct
  • Contributed genes to Melanesians, Aboriginal Australians, and parts of East and Southeast Asia, including variants affecting altitude adaptation (e.g. EPAS1)

Modern Homo sapiens
  • Emerged in Africa by ~300 ka
  • Retained genetic continuity with earlier African populations
  • Dispersed out of Africa multiple times, beginning ~70–60 ka
  • Interbred repeatedly with Neanderthals and Denisovans



The key point: no clean branching tree

Human evolution is reticulate, not linear:
  • Species boundaries were porous
  • Gene flow occurred repeatedly
  • Populations diverged, adapted, re-merged, and diverged again

Homo erectus is not a side branch that “went extinct”, but a foundational grade from which multiple later lineages emerged. DAN5 fits neatly into this framework: a locally isolated erectus population retaining ancestral traits while others continued evolving elsewhere.



Why this matters

This picture:
  • Explains mosaic anatomy in fossils
  • Accounts for genetic admixture in living humans
  • Makes sense of long timescales and geographic diversity
  • Is incompatible with any model of recent, perfect, single-pair creation

Instead, it shows that our species is the outcome of millions of years of population dynamics, not a single moment of design.

A new fossil face sheds light on early migrations of ancient human ancestor
A New Fossil Face Sheds Light on Early Migrations of Ancient Human Ancestor
A 1.5-million-year-old fossil from Gona, Ethiopia reveals new details about the first hominin species to disperse from Africa. Summary: Virtual reassembly of teeth and fossil bone fragments reveals a beautifully preserved face of a 1.5-million-year-old human ancestor—the first complete Early Pleistocene hominin cranium from the Horn of Africa. This fossil, from Gona, Ethiopia, hints at a surprisingly archaic face in the earliest human ancestors to migrate out of Africa.

A team of international scientists, led by Dr. Karen Baab, a paleoanthropologist at the College of Graduate Studies, Glendale Campus of Midwestern University in Arizona, produced a virtual reconstruction of the face of early Homo erectus. The 1.5 to 1.6 million-year-old fossil, called DAN5, was found at the site of Gona, in the Afar region of Ethiopia. This surprisingly archaic face yields new insights into the first species to spread across Africa and Eurasia. The team’s findings are being published in Nature Communications.

We already knew that the DAN5 fossil had a small brain, but this new reconstruction shows that the face is also more primitive than classic African Homo erectus of the same antiquity. One explanation is that the Gona population retained the anatomy of the population that originally migrated out of Africa approximately 300,000 years earlier.

Gona, Ethiopia

The Gona Paleoanthropological Research Project in the Afar of Ethiopia is co-directed by Dr. Sileshi Semaw (Centro Nacional de Investigación sobre la Evolución Humana, Spain) and Dr. Michael Rogers (Southern Connecticut State University). Gona has yielded hominin fossils that are older than 6.3 million years ago, and stone tools spanning the last 2.6 million years of human evolution. The newly presented hominin reconstruction includes a fossil brain case (previously described in 2020) and smaller fragments of the face belonging to a single individual called DAN5 dated to between 1.6 and 1.5 million years ago. The face fragments (and teeth) have now been reassembled using virtual techniques to generate the most complete skull of a fossil human from the Horn of Africa in this time period. The DAN5 fossil is assigned to Homo erectus, a long-lived species found throughout Africa, Asia, and Europe after approximately 1.8 million years ago.

How did the scientists reconstruct the DAN5 fossil?

The researchers used high-resolution micro-CT scans of the four major fragments of the face, which were recovered during the 2000 fieldwork at Gona. 3D models of the fragments were generated from the CT scans. The face fragments were then re-pieced together on a computer screen, and the teeth were fit into the upper jaw where possible. The final step was “attaching” the face to the braincase to produce a mostly complete cranium. This reconstruction took about a year and went through several iterations before arriving at the final version.

Dr. Baab, who was responsible for the reconstruction, described this as “a very complicated 3D puzzle, and one where you do not know the exact outcome in advance. Fortunately, we do know how faces fit together in general, so we were not starting from scratch.”

What did scientists conclude?

This new study shows that the Gona population 1.5 million years ago had a mix of typical Homo erectus characters concentrated in its braincase, but more ancestral features of the face and teeth normally only seen in earlier species. For example, the bridge of the nose is quite flat, and the molars are large. Scientists determined this by comparing the size and shape of the DAN5 face and teeth with other fossils of the same geological age, as well as older and younger ones. A similar combination of traits was documented previously in Eurasia, but this is the first fossil to show this combination of traits inside Africa, challenging the idea that Homo erectus evolved outside of the continent.

I'll never forget the shock I felt when Dr. Baab first showed me the reconstructed face and jaw. The oldest fossils belonging to Homo erectus are from Africa, and the new fossil reconstruction shows that transitional fossils also existed there, so it makes sense that this species emerged on the African continent,” says Dr. Baab. “But the DAN5 fossil postdates the initial exit from Africa, so other interpretations are possible.

It is remarkable that the DAN5 Homo erectus was making both simple Oldowan stone tools and early Acheulian handaxes, among the earliest evidence for the two stone tool traditions to be found directly associated with a hominin fossil.

Future Research

The researchers are hoping to compare this fossil to the earliest human fossils from Europe, including fossils assigned to Homo erectus but also a distinct species, Homo antecessor, both dated to approximately one million years ago.

Comparing DAN5 to these fossils will not only deepen our understanding of facial variability within Homo erectus but also shed light on how the species adapted and evolved.

There is also potential to test alternative evolutionary scenarios, such as genetic admixture between two species, as seen in later human evolution among Neanderthals, modern humans and “Denisovans.” For example, maybe DAN5 represents the result of admixture between classic African Homo erectus and the earlier Homo habilis species.

We’re going to need several more fossils dated between one to two million years ago to sort this out.

Taken together, the evidence leaves little room for the idea that Homo erectus was a dead-end curiosity, neatly replaced by something entirely new. Instead, it represents a long-lived, widely dispersed, and internally diverse population complex that provided the evolutionary substrate from which later human lineages emerged. Its descendants were not produced by sudden leaps or special creation events, but by the ordinary, observable processes of population divergence, isolation, and adaptation acting over deep time.

Modern Homo sapiens, Neanderthals, and Denisovans did not arise as separate “kinds”, nor did they follow clean, branching paths. They represent regional outcomes of this erectus-derived heritage, shaped by geography, climate, and repeated episodes of contact and interbreeding. The genetic legacy of those interactions is still present in living humans today, providing independent confirmation of what the fossil record has long been indicating.

What emerges is not a ladder of progress but a dynamic, reticulated history: populations spreading, fragmenting, evolving in isolation, and reconnecting again. Fossils such as DAN5 are not anomalies to be explained away; they are exactly what we should expect from evolution operating on structured populations across continents and hundreds of thousands of years.

For creationism, this is deeply inconvenient. For evolutionary biology, it is precisely the kind of rich, internally consistent picture that arises when multiple independent lines of evidence converge on the same conclusion: humanity is the product of a long, complex evolutionary history, not a recent act of design.

Malevolent Design - The Diseases That Wouldn't Exist if an Intelligent Designer Was Real


Genomic Maps Untangle the Complex Roots of Disease

In another major embarrassment for those creationists who understand it, researchers at the Gladstone Institutes and Stanford University have developed a method for linking the genome of a cell to diseases caused by specific gene variants. They have recently published their findings, open access, in Nature.

Creationists insist that the human genome was intelligently designed, with every outcome the result of “complex specified information” which, according to Discovery Institute Fellow William A. Dembski, constitutes definitive evidence of intelligent design. If this were true, it would follow that genes which cause disease were intelligently designed to cause those diseases.

The difficulty deepens for creationists when one considers that many diseases involve multiple genes, sometimes hundreds or even thousands, all of which must possess the “correct” variants for the disease to emerge. In other words, some diseases not only depend on Dembski’s “complex specified genetic information”, but also conform to Michael J. Behe’s proposed hallmark of intelligent design: irreducible complexity.

Unless creationists invoke an additional creator—one over whom their reputedly omnipotent and omniscient god has no control—their supposedly intelligent designer must have deliberately created these gene variants to produce the suffering they cause.

By contrast, the evolutionary explanation requires no such mental gymnastics. The existence of genetic variants is exactly what evolutionary theory predicts, and provided such variants remain rare within a population, there is little selective pressure to remove them. A genome produced by an omniscient, perfect designer, however, would contain no such variants: the original design would be flawless, as would the mechanisms responsible for replicating it. The very existence of gene variants is therefore evidence against intelligent design.

The technique developed by the research team is sensitive enough to examine the entire genome and determine which genes influence which cell types. This makes it possible to identify which genes contribute to particular diseases. In cases where a single gene is involved, this can be relatively straightforward, but where many genes are implicated, it can be extremely difficult to disentangle their individual effects—precisely the problem this new technique helps to overcome.

Refuting Creationism - How Consciousness Evolved - No God-Magic Required


Why Do We Have a Consciousness? | Newsportal - Ruhr-Universität Bochum

Having recently watched a grey squirrel carefully plot a route through a line of trees, I was struck by the sophistication of its behaviour. It was not simply moving at random. It clearly knew where it wanted to go and was able to take into account such factors as how much slender branches would bend under its weight, how wide a gap it could safely jump, and—perhaps most importantly—exactly where it was within its own mental map of the environment. It is difficult to see how such behaviour could be possible in a creature that was not conscious and, to some degree, self-aware.

In animal psychology, there is now little doubt that many vertebrates possess some level of self-awareness and therefore consciousness. The remaining debate has centred not on whether consciousness exists in non-human animals, but on how it arose. The fact that consciousness is found across a wide range of vertebrates, and even in molluscs such as cephalopods, suggests either that it originated in a remote common ancestor or that it evolved independently multiple times through convergence. Either way, this strongly points to an evolutionary origin.

According to two papers published in a special edition of the journal Philosophical Transactions of the Royal Society B, by working groups led by Professors Albert Newen and Onur Güntürkün at Ruhr University Bochum in Germany, consciousness can indeed be explained as the outcome of an evolutionary process, with each step conferring a selective advantage. Moreover, consciousness only makes sense as an evolved biological function. The two open-access papers can be found here and here.

This work is bound to provoke another bout of denialism among creationists, for whom consciousness remains one of the standard “impossible to explain without supernatural intelligence” fallback arguments. As with abiogenesis and the Big Bang, the reasoning typically amounts to: “Science hasn’t explained it and I don’t understand how it could, therefore God did it.” This false dichotomy conveniently removes any obligation to provide evidence in support of the supernatural claim. Creationists also like to flatter themselves that consciousness is a uniquely human trait and thus evidence of special creation. In scientific terms, however, this does not even rise to the level of a hypothesis: it proposes no mechanism, makes no testable predictions, and is unfalsifiable by design. It is, in essence, wishful thinking rooted in the belief that the Universe is obliged to conform to personal expectations.

By contrast, the Ruhr University team have identified three distinct levels of consciousness and demonstrated the evolutionary advantage of each, drawing on detailed studies of birds that show parallel forms of consciousness to those seen in humans. These levels are:
  1. Basic arousal — such as the perception of pain, which signals that harm is occurring and that corrective action is required.
  2. General alertness — awareness of the broader environment, allowing threats and opportunities to be recognised and responded to appropriately.
  3. Reflexive (self-)consciousness — the ability to place oneself within an environment, learn from past experience, anticipate future outcomes, and formulate an action plan; in other words, to construct a narrative with oneself as a participant.

Refuting Creationism - Balanophora And Why Creationists Pretend Not To Notice Them

Balanophora laxiflora

A selection of the sampled Balanophora plants. (a) B. japonica (left and center: Kyushu, Japan; right: Taiwan), (b) B. mutinoides (Taiwan), (c) B. tobiracola (from left: Okinawa, Japan; Taiwan), (d) B. subcupularis (Kyushu, Japan), (e) B. fungosa ssp. fungosa (from left: Okinawa, Japan; Taiwan), (f) B. yakushimensis (from left: Kyushu, Japan; Taiwan), (g) B. nipponica (Honshu, Japan).
Among flowering plants, few groups look as alien as Balanophora. These strange, tuberous parasites lack leaves, lack roots in any conventional sense, and contain no chlorophyll. They spend almost their entire lives embedded within the roots of other plants, emerging only briefly to flower. To a casual observer, they barely resemble plants at all — and that superficial oddity has sometimes been exploited by creationists as evidence that they represent a fundamentally distinct “kind”.

In reality, Balanophora are not evolutionary outliers. They are a textbook example of what happens when natural selection acts over long periods on a parasitic lineage.

Where Balanophora fit in the plant kingdom

Molecular phylogenetics places Balanophora firmly within the angiosperms, in the order Santalales. This is the same order that includes mistletoes, sandalwood, and a range of hemi- and holoparasitic plants. Their closest relatives are photosynthetic or partially parasitic species, providing a clear evolutionary gradient from free-living autotrophs to obligate parasites.

This placement is not controversial. It is supported by nuclear, mitochondrial, and plastid gene sequences, as well as by reproductive and developmental traits. Balanophora are deeply nested within the flowering plant family tree, not perched mysteriously at its base.
Angiosperms

├── Basal angiosperms (Amborella, water lilies, etc.)

├── Monocots

└── Eudicots

    ├── Rosids
    │
    ├── Asterids

    └── Santalales

        ├── Hemiparasites (e.g. Viscum – mistletoe)
        └── Holoparasites
            ├── Balanophoraceae (Balanophora)
            └── Other parasitic families


Why this placement matters
  1. Balanophora are deeply nested, not basal.

    They are not an early-diverging angiosperm lineage. They sit well within the eudicots, inside an order dominated by parasitism. This is exactly what evolution predicts for a lineage that became parasitic rather than being created as such.

    Creationism would expect either:
    • A distinct, isolated “kind”, or
    • No consistent phylogenetic signal at all

    Instead, Balanophora fall precisely where descent with modification says they should.
  2. Transitional relatives exist

    Within Santalales you can trace a graded series:
    • Fully photosynthetic plants
    • Root parasites that still photosynthesise
    • Plants with reduced photosynthesis
    • Fully holoparasitic forms like Balanophora

    This gradient is phylogenetic, not just ecological. It maps cleanly onto the tree.
  3. Plastid phylogeny seals the case

    Even though Balanophora plastids are massively reduced, the genes that remain:
    • Cluster with chloroplast genes of Santalales
    • Show derived mutations consistent with long-term loss of photosynthesis
    • Cannot be explained as independently created organelles

    In other words, the plastids themselves remember their ancestry.

Creationism, which insists on fixed, separately created categories, has no principled way to explain why these plants fall exactly where evolution predicts they should.

Creationism Refuted - Evolution of Parasitic Plants by LOSS of Complexity

Balanophora

Species of Balanophora are parasitic plants that live underground and emerge above ground only during the flowering season — and some species even reproduce exclusively asexually. This collage shows species studied to establish how the plants of that group relate to each other, how they modified their plastids and how their reproduction fits into their ecology.

How parasitic, asexual plants evolve and live | Kobe University News site

A recently published paper in New Phytologist on the biology of the parasitic plants *Balanophora*, by three botanists from the Okinawa Institute of Science and Technology, Japan, together with Kenji Suetsugu of Kobe University, should cause consternation in creationist circles — if only they were not so practised at dismissing any evidence that contradicts their superstition.

Not only does the study highlight the well-known problem of parasitism, which creationists typically attempt to wave aside by invoking “The Fall” — thereby exposing any claim that creationism is a genuine science rather than a form of Christian fundamentalism as a lie — it also reveals that the evolution of this group of plants has involved a loss of complexity, coupled with the repurposing of redundant structures. The result is what creationists themselves would describe as irreducible complexity, accompanied by precisely the kind of “complex specified genetic information” that William A. Dembski insists should be regarded as evidence for intelligent design.

Then there is the problem of an overly complex solution, in that, instead of simply giving the plants the genes they need, some essential genes have been included in cell organelles These are clearly repurposed chloroplasts that no longer perform photosynthesis, produced by an evolutionary process that creationists deny - leaving them to explain why an intelligent designer opted for such an overly complex solution.

Finally, the findings rely entirely on the Theory of Evolution to explain and make sense of the observations, with no hint of any need to invoke the supernatural magic upon which creationism depends — despite repeated assurances from creationist cult leaders to their followers that such a moment is imminent, a promise they have been making for over half a century.

Creationism Refuted - Dugongs and Manatees Blow Creationism Out of the Water.

Dugong
Manatee

Dugongs and manatees — the surviving members of the order Sirenia — are among the most revealing mammals when it comes to understanding evolution. Fully aquatic yet air-breathing, specialised yet constrained by their ancestry, they provide one of the clearest examples of how complex organisms arise through gradual modification rather than sudden creation.
Unlike whales, which are now well known as a textbook evolutionary transition, sirenians are less familiar to the public. That makes them especially valuable, because their fossil record is remarkably complete, their evolutionary trajectory is straightforward, and their genetic relationships were discovered independently of their anatomy. Taken together, they present a problem for creationism that cannot be explained away.

Terrestrial origins. The earliest known sirenians lived around 50 million years ago and were unmistakably terrestrial or semi-aquatic mammals.

Ancient Manatee Relative Reveals That Sea Cows Have Engineered the Arabian Gulf’s Seagrass Ecosystems for Over 20 Million Years | Smithsonian Institution

Scientists from the Smithsonian’s National Museum of Natural History, together with collaborators at Qatar Museums, have just announced the discovery of 20-million-year-old fossils of a sea cow that was a miniature version of living dugongs, and which almost certainly lived in the same seagrass meadows as modern dugongs.

The scientists have published their findings in the journal PeerJ.

If there is one thing that has creationists scraping the bottom of their barrel for reasons to dismiss evidence, it is news of fossils that are tens of millions of years older than they believe the universe is — simply because Bronze Age authors of their favourite source book, the Bible, said so.

In their determination to show the world that nothing can make them change their belief in the demonstrably absurd, creationists will resort to false accusations of lying against scientists, claim they are incompetent, or insist that they used dating methods they claim (incorrectly) to have been proven false, all in an attempt to preserve their beliefs. It is as though they imagine the entire global scientific community, and all the research institutions within it, exist solely to disprove the Bible in order to make creationists change their minds.

For rational people without such an egocentric view of the world, however, discoveries such as these miniature dugongs help to paint a fascinating picture of how species — and the ecosystems of which they are a part — have evolved over time. The fossils were found about 10 miles from a bay of seagrass that is prime habitat for modern dugongs.
