Creationism Refuted - A 'Transitional Species' That is Probably Another Ancestral Hominin

A brief communication, published last November in the American Journal of Biological Anthropology may, if creationists never read past the title (as usual), have produced a frisson of excitement in those circles. It questioned the taxonomic status of one of the most complete fossil skeletons of an early ancestral hominin, Australopithecus prometheus, popularly known as “Little Foot”.

However, reading even a little further would have turned that excitement into disappointment — assuming, of course, that they understood what they were reading. The authors were not questioning whether the fossil was ancestral at all, but whether it had been assigned to the correct position in the hominin family tree, or whether it should instead be recognised as a distinct ancestral hominin species. In other words, this was a discussion about how many transitional species there are, not whether transitional species exist at all.

The only crumb of comfort available to creationists is the familiar claim that this demonstrates how science “keeps changing its mind”, something they take as evidence that science is fundamentally unreliable—presumably including even those parts they routinely misrepresent as supporting their beliefs.

For anyone who understands the scientific method, and the importance of treating all knowledge as provisional and contingent on the best available evidence, this paper represents the principle functioning exactly as it should. Far from being a weakness, this willingness to revise conclusions in the light of new information is what makes science self-correcting and progressively more accurate over time.

The authors of the paper — a team led by La Trobe University adjunct Dr Jesse Martin—carried out a new analysis of the “Little Foot” fossils and concluded that the specimen was probably placed in the wrong taxon when first described on the basis that it does not share the same “unique suite of primitive and derived features” as Australopithecus africanus. Since that initial assessment, additional fossils of A. prometheus have been discovered, and it has become clear that “Little Foot” also differs from those specimens. At the same time, it remains sufficiently distinct from A. africanus that reassignment to that species is not justified. In short, it possesses its own unique combination of primitive and derived traits and should therefore be recognised as a separate species.

Naturally, there is no real comfort here for creationists. The phrase “suite of primitive and derived features” is simply palaeontological shorthand for evidence of descent with modification—what Darwin referred to as transitional forms. It follows that the researchers involved have no doubt whatsoever that the species under discussion evolved from earlier ancestors, and there is no hint that they believe it was spontaneously created, without ancestry, by magic.

Refuting Creationism - Now It's Evidence of Bipedalism in a Hominin From 7 Million Years Ago

Anthropologists Offer New Evidence of Bipedalism in Long-Debated Fossil Discovery

We are only three days into 2026 and already creationism is facing an avalanche of new evidence against it and in favour of evolution on an ancient Earth in a vastly older Universe — directly contradicting the Bronze Age origin myths that creationists cling to with the desperation of a drunk clutching a lamppost.

The latest blow comes from the New York University Department of Anthropology, where a team of researchers led by Associate Professor Scott Williams, working with colleagues from the University of Washington, Chaffey College, and the University of Chicago, have carried out a detailed re-examination of fossil remains attributed to Sahelanthropus tchadensis. Their analysis provides strong evidence that this species was bipedal and shared several key skeletal characteristics with later bipedal hominins, including the australopithecines and members of the genus Homo.

Sahelanthropus tchadensis was discovered in the early 2000s, and its place in human evolution has been debated ever since. Some researchers argued it might represent an extinct ape rather than a stem hominin. Evidence for habitual bipedalism, however, strongly favours the latter interpretation, making S. tchadensis the earliest known human ancestor currently identified in the fossil record.

As such, it becomes yet another example of the transitional species that creationists continue to insist do not exist, often under the mistaken belief that Charles Darwin — whom they treat as the final authority on all matters evolutionary — admitted that the absence of transitional forms was a serious problem for his theory. In reality, Darwin explicitly predicted that such fossils would eventually be found, and the subsequent century and a half of palaeontology has repeatedly confirmed that prediction.

The discovery is of a point of attachment on the femur of a ligament only found in bipedal hominins. The importance of bipedalism in human evolution cannot be overstated. Habitual upright walking is one of the defining characteristics that separates hominins from other apes, reflecting a fundamental shift in anatomy, locomotion, and behaviour. It requires extensive reorganisation of the skeleton, including changes to the position of the foramen magnum, the curvature of the spine, the shape of the pelvis, the proportions of the limbs, and the structure of the feet. Because these adaptations are complex, interdependent, and leave clear signatures in fossilised bones, bipedalism is not a trivial or ambiguous trait. Evidence for it in Sahelanthropus tchadensis therefore places this species firmly on the human lineage and pushes the origin of upright walking — and with it the human evolutionary trajectory — back far earlier than creationist models allow.

Scott Williams’ team have now published their findings, open access, in Science Advances.

Metabolic Analyses of Animal Fossils Helps Scientists Reconstruct Million-Year-Old Environments

The bad news for creationism continues unabated. Scientists led by Professor Timothy G. Bromage of the Department of Molecular Pathobiology at New York University College of Dentistry have developed a technique that opens an entirely new window onto the deep past. By analysing metabolites preserved in fossilised bones, the researchers are able to extract detailed biological and environmental information from animals that lived between 1.3 and 3 million years ago.

The team have published their findings in Nature, describing a method that pushes palaeobiology well beyond traditional morphology-based reconstruction.

The significance of this technique lies in its ability to reconstruct ancient environments with remarkable precision. From the chemical signatures locked within fossil bone, researchers can infer temperature, soil conditions, rainfall patterns, vegetation, and even the presence of parasites. The resulting picture is one of ecosystems changing over time, with animals adapting in step with shifting environments — exactly what evolutionary theory predicts, and wholly incompatible with the childish notion of magical creation a few thousand years ago or a recent biological reset caused by a genocidal flood.

Creationism Refuted - A Terrible End to a Bad Year for Creationism - a 37-Million-Year-Old Transitional Fossil Snake

“Weird” new species of ancient fossil snake discovered in southern England | Natural History Museum

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).

Creationism Refuted - Highly Accurate Dating of Dinosaur Eggs


The Gobi Desert, where many dinosaur eggs have been found.
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.

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.

        ├── 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
Photo credit: Ze Wei, Plant Photo Bank of China

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.

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.
