Fig. 9: Schematic of microbial succession and biogeochemical processes in serpentinite mud at the Mariana forearc.
This schematic depicts lipid biomarker transitions from pelagic sediment communities to extremophiles adapted to high pH and redox conditions in serpentinite mud. The Mariana forearc biosphere is fueled by alkaline serpentinization fluids enriched in H₂, CH₄, DIC, and organic acids, sustaining specialized microbial communities. Lipid and stable carbon isotope data reveal a shift from relict methanogenic archaea, likely engaged in hydrogenotrophic methanogenesis, to a later ANME-SRB community mediating anaerobic oxidation of methane (AOM). Changes in substrate availability likely drove this transition. Distinct lipid signatures, including unsaturated diethers, acyclic GDGTs, and ether-based glycolipids, highlight adaptations to pH stress, phosphate limitation, and fluctuating redox conditions. The presence of in-situ branched GDGTs suggests previously uncharacterized bacterial communities persisting in these ultra-oligotrophic conditions. The Mariana forearc serpentinite biosphere, shaped by episodic fluid flow and substrate shifts, provides insights into deep-sea subsurface habitability.

Fats provide clues to life at its limits in the deep sea

Researchers at MARUM – Bremen University’s Centre for Marine Environmental Sciences – have made a discovery, just published open access in the journal Communications Earth & Environment, which, properly understood, should make depressing reading for creationists.

They have found living organisms both on and within the ocean floor, surviving in conditions where normal life would be impossible. These microorganisms inhabit mud volcanoes with a pH of 14, metabolising hydrogen and carbon to form methane by drawing energy from minerals in the surrounding rock. In other words, they live entirely without oxygen and with almost no organic matter, synthesising all they need from inorganic sources.

Informed creationists will recognise that these organisms directly refute their frequent assertion that life cannot arise from non-life — because producing life from non-life is precisely what these microorganisms are doing.

This also contradicts the biblical claim that all living things were created for the benefit of humans, since there is no conceivable way these organisms could serve any human purpose. Of course, to be fair, the authors of the Bible were completely ignorant of microorganisms, deep-ocean mud volcanoes, and chemosynthetic metabolism. They could only attempt to explain the larger creatures that lived in the limited region around their homes in the Canaanite hills.

And, as any informed creationist should also understand, these are exactly the sort of extreme conditions that biologists believe may have fostered the emergence of the earliest living organisms during the origin of life on Earth — once again undermining any claim that abiogenesis is impossible.

Background^ Chemosynthetic Extremophiles. Chemosynthetic extremophiles are microorganisms that survive in environments too hostile for most known life. Instead of relying on sunlight for energy (as photosynthetic organisms do), they extract energy from chemical reactions involving inorganic compounds such as hydrogen, methane, ammonia, or sulphides.

These organisms thrive in extreme conditions — high pressure, intense heat or cold, high salinity, or extreme acidity or alkalinity — where oxygen and organic nutrients are scarce or absent. They are commonly found around deep-sea hydrothermal vents, cold seeps, and mud volcanoes, as well as in acidic mines and alkaline lakes.

Chemosynthesis typically involves oxidising inorganic molecules (e.g. hydrogen sulphide, hydrogen, or iron) to obtain energy, which is then used to convert carbon dioxide or methane into organic compounds. This allows entire ecosystems — such as those around black smokers on the ocean floor — to exist entirely independent of sunlight.

These extremophiles are of major interest to biologists and astrobiologists because they demonstrate that life can originate and persist in conditions once thought uninhabitable. Their existence supports hypotheses that early life on Earth, and potentially elsewhere in the universe, may have begun in similar environments where energy was derived chemically rather than from sunlight.

The research is explained in a Universität Bremen news item.

Researchers use lipid biomarkers to reveal survival strategies in extreme ecosystems

Diverse life forms exist on and within the ocean floor. These primarily consist of microbes, tiny organisms that can cope with extreme environmental conditions. These include high pressures and salinities, as well as extreme pH values and a limited supply of nutrients. A team of researchers has now been able to detect microbial life in two newly discovered mud volcanoes with very high pH values. Their findings have been published in the professional journal Communications Earth & Environment.

In their study, first author Palash Kumawat of the Geosciences Department at the University of Bremen and his colleagues used lipid biomarker analyses to decipher the survival strategies of the microbes in this harsh ecosystem. The high pH value of 12 here is especially challenging for deep-sea life; This is one of the highest known value so far in ecosystems. In order to detect life at all, the researchers had to resort to special methods of trace analysis. In this situation, the detection of DNA can be ineffectual where there is a low number of living cells.

But we were able to detect fats. With the help of these biomarkers we were able to obtain insights into the survival strategies of methane- and sulfate-metabolizing microbes in this extreme environment.

Microbial communities metabolize carbon in the deep sea and thereby contribute to the global carbon cycle. However, the communities that the team describe in the publication draws its energy from minerals within rocks and gases such as carbon dioxide and hydrogen to produce methane, for example, an important greenhouse gas. These processes initially take place independently of the ocean above. The lipids also provide clues to the age of the microorganisms. If the cellular biomolecules are intact, they represent a living or recently dead community. If they are not intact, they are geomolecules, which means that they are fossil communities from the past. According to Kumawat, the combination of isotopes and the lipid biomarkers indicates that multiple microbial communities now live in this inhospitable habitat and have lived there in the past.

This distinction helps us when working in areas with extremely low biomass and nutrient deficiency.

Dr. Florence Schubotz, organic geochemist at MARUM – Center for Marine Environmental Sciences at the University of Bremen and co-author of the study, adds:

What is fascinating about these findings is that life under these extreme conditions, such as high pH and low organic carbon concentrations is even possible. Until now, the presence of methane-producing microorganisms in this system has been presumed, but could not be directly confirmed. Furthermore, it is simply exciting to obtain insights into such a microbial habitat because we suspect that primordial life could have originated at precisely such sites.

The samples for the study come from a sediment core that was retrieved by the Research Vessel Sonne in 2022 during Expedition SO 292/2. Not only were the scientists able to discover the previously unknown mud volcanoes of the Mariana forearc during this cruise, but also to sample them.
The samples were obtained as part of the Cluster of Excellence “The Ocean Floor – Earth's Uncharted Interface.” Palash Kumawat and his colleagues are now planning to cultivate organisms in an incubator to find out more about their nutrient preferences in inhospitable environments.

Abstract
Present-day serpentinization systems, such as that at the Mariana forearc, are prominent sources of reduced volatiles, including molecular hydrogen (H₂) and methane (CH₄), and are considered analogs for chemosynthetic ecosystems on early Earth. However, seepage of serpentinization fluids through mud volcanoes at the Mariana forearc seafloor is defined by high pH, and nutrient scarcity, creating challenging conditions for microbial life. We present geochemical and lipid biomarker evidence for a subsurface biosphere shaped by episodic substrate availability, highlighting microbial persistence across steep geochemical gradients within serpentinite mud. Light stable carbon isotope compositions from diagnostic lipids reveal a temporal shift from hydrogenotrophic methanogenesis to sulfate-dependent anaerobic methane oxidation. Membrane adaptations, including unsaturated diether, acyclic and branched tetraether, and ether-based isoprenoidal and non-isoprenoidal glycosidic lipids, reflect microbial strategies for coping with this extreme environment. Our findings establish the Mariana forearc as a unique serpentinite-hosted biosphere, where life operates at the fringes of habitability.

Introduction
The subseafloor biosphere is estimated to harbor up to 15% of the global biomass¹. Recent advances in deep biosphere research have improved our understanding of the distribution and diversity of microbial life in the rocky oceanic crust, especially around hydrothermal vents^2,3. This subseafloor biosphere has to adapt to limited carbon and nutrient availability, accompanied by harsh environmental conditions such as high temperature and pressure, elevated salinity, and/or extreme pH levels⁴. Serpentinization of mantle rocks by seawater can generate high levels of H₂^5,6 that, in turn, drives the abiotic reduction of carbon to form CH₄ and other organic compounds⁷, which can be oxidized by chemosynthetic organisms^8,9,10, forming the foundation for a serpentinite biosphere¹¹. The type locality for such a serpentinite biosphere is the Lost City hydrothermal vent field near the Mid-Atlantic Ridge, where hydrothermal fluids fuel microbial communities in active and inactive vent structures¹². Methanogenic archaea there are found in active brucite-calcite vents, whereas older carbonate chimneys host a syntropic consortium of anaerobic methanotrophic archaea (ANME) and sulfate-reducing bacteria (SRB) that perform the anaerobic oxidation of methane (AOM)^13,14.

The process of serpentinization takes place in a range of geotectonic settings, including rifted continental margins, mid-oceanic ridges, transform faults, and convergent margins. Among the latter, the forearc of the Mariana subduction system is of particular interest because it provides access to serpentinization products from within an active subduction zone. There, dewatering of the subducting Pacific Plate leads to serpentinization of the mantle wedge of the overriding Philippine Sea Plate. Faults reaching 10–25 km deep into the forearc allow serpentinite, together with fluids derived from the subducting slab, to buoyantly rise and form large ‘serpentinite mud volcanoes’ on the seafloor^15,16 (Fig. 1a, c). Fluids venting from the mud volcanoes are cold (<3.5 °C), hyperalkaline (pH up to 12.6), and enriched in H₂ and CH₄ (both up to ~1 mM)^17,18 and slab-derived sulfate (SO₄²⁻; up to 28 mM)¹⁹. These fluids are also enriched in short-chain organic acids like acetate (0.04 mM) and formate (0.1 mM), contributing ~20–30% of the dissolved organic carbon (DOC)²⁰, and in methanol (0.03 mM)^20,21. The δ¹³C of CH₄ (−37‰ to 2‰), acetate (−8‰), formate (4.8‰) and methanol (2.3‰) point to their abiotic formation^17,21. While these serpentinization fluids sustain chemosynthetic life at the seafloor^22,23, the functioning and extent of the chemosynthetic microbial biosphere below the seafloor remains largely unknown. Cell counts in the serpentinite mud are variable, but overall low (101 to 106 cells cm−3)^20,24, presumably because of the high pH and intermittent fluid seepage^13,16. Extremophilic archaea are believed to perform AOM as inferred from the detection of phospholipid-derived diphytanyl diethers and reduced sulfur species in the formation fluids18. Metabolic transcripts for denitrification and AOM were interpreted as evidence for nitrate-dependent AOM within the serpentinite mud volcanoes²⁴. Although AOM is considered thermodynamically favorable here^19,25, direct evidence for AOM and its associated microorganisms is still lacking. Methanogenesis is a common metabolic strategy in serpentinization systems¹³, but since CH₄ formation at the Mariana forearc is dominantly abiotic, the extent of microbial methanogenesis remains uncharacterized.

This study documents AOM coupled to sulfate reduction as a key metabolic process in the Mariana forearc, indicating the importance of methane cycling for the indigenous microbial community. Our findings also provide evidence of relict methanogenesis in the serpentinite mud, where its temporal distribution is possibly controlled by variable substrate availability. We present a comprehensive lipid biomarker and isotopic record from the Pacman and Subetbia mud volcanoes, providing insights into the habitability and survival strategies of extremophilic chemosynthetic life in this serpentinite biosphere.

Creationists often insist that “life cannot come from non-life,” claiming that the origin of life through natural processes — abiogenesis — is impossible. Yet these microorganisms thriving deep beneath the ocean floor undermine that argument completely. They demonstrate that life does not require sunlight, oxygen, or organic nutrients. Instead, it can sustain itself entirely through chemical reactions involving inorganic matter, precisely the kind of chemistry that would have been available on the early Earth long before photosynthesis or complex ecosystems evolved.

These microbes survive by harnessing energy from the oxidation of minerals and gases such as hydrogen and carbon, producing methane as a by-product. In doing so, they show that biological systems can indeed emerge and persist using nothing more than inorganic chemistry and environmental energy sources. If life can continue this way today — in conditions strikingly similar to those thought to exist on the early Earth — then it is perfectly reasonable to infer that the same processes could once have given rise to life itself.

Creationists’ claim that life from non-life violates natural law is based on a false analogy with modern life, which relies on pre-existing organic systems. But these extremophiles illustrate that the boundary between “non-living” chemistry and “living” biochemistry is not a rigid wall — it is a continuum. The metabolic reactions that sustain these organisms are direct chemical extensions of the mineral and geochemical reactions occurring in their surroundings. Life in such places does not appear magically; it emerges naturally from the physical and chemical conditions of its environment.

Far from being a problem for evolutionary science, discoveries like this one strengthen the case for a natural origin of life. They show that even today, the chemistry of life and the chemistry of rocks remain intimately connected. To deny that such chemistry could, under the right conditions, cross the threshold into life is to deny the very evidence creationists claim to seek — evidence that life can, and demonstrably does, arise from the non-living world through the workings of natural law.

Sadly, the same creationists who continue to parrot the 'no life from non-life' fallacy won't have understood a word of that and will continue to make proven false claims.

Refuting Creationism - Diverging Sloth Genomes - Just As The TOE Predicts

[left caption]

[right caption]

Deforested genomes: scientists find signs of environmental degradation in the genomes of the endangered Maned Sloths - Leibniz Institute for Zoo and Wildlife Research

The discovery fits seamlessly within the framework of Darwinian evolution. Two once-connected populations became isolated and exposed to different ecological conditions, followed their own evolutionary paths. Over time, their genomes accumulated distinct mutations reflecting adaptation, genetic drift, and local environmental pressures. The result is two clearly defined species whose divergence can be explained entirely by natural processes acting over generations — a textbook demonstration of evolution in action.

Yet this same process now drives both species along a far more perilous trajectory. As their habitats continue to shrink and fragment, their populations are losing genetic diversity and becoming increasingly inbred. Evolution has no foresight or purpose; it cannot plan for the future or reverse the consequences of environmental destruction. The very mechanism that once diversified life on Earth can, under relentless human pressure, just as readily lead to extinction.

There is no sign of “intelligent design” in this grim reality — only the blind, natural workings of selection, drift, and chance operating within a degraded environment. If a designer were guiding life towards some higher purpose, it would hardly produce a situation where its own creations are being driven to extinction by the ecological collapse of their habitats. The plight of the maned sloths stands as a vivid reminder that life’s diversity, beauty, and tragedy arise not from supernatural intent, but from the impersonal and unyielding logic of evolution.

As world leaders prepare for COP30 in Brazil, the message from the maned sloths’ genomes could not be clearer: conservation must be guided by evolutionary science and ecological understanding, not by comforting myths of divine oversight. Only by recognising the true, natural processes that shape life can we hope to protect what remains of it.

Half-billion-year-old parasite still threatens shellfish | UCR News | UC Riverside

It’s Coelacanth time for creationist disinformers again.

Hilariously, I’ve known creationists claim that the 'fact' that coelacanths haven’t changed for 200 million years somehow proves the “evilutionists” are wrong and that Earth is only 6,000–10,000 years old. How they managed to examine the genome of a 200-million-year-old fossil remains a mystery, but DNA appears to play no part in a creationist’s definition of evolution.

So, for an alternative fallacious argument, here’s an even older fossil that’s still around today, apparently in much the same form as it was almost half a billion years ago. It’s a parasitic worm that attacks oysters. The details have just been published in the journal iScience by scientists led by University of California, Riverside palaeobiologist Karma Nanglu, with colleagues from Harvard.

The parasitic, soft-bodied bristle worm belongs to a group called the spionids. It’s common in today’s oceans and feeds on the shells of mussels and oysters, leaving a characteristic question mark-shaped track in their shells. Their parasitism doesn’t kill the shellfish but probably shortens their lifespan.

The story of our origins is written in the ground of Africa. It is real, tangible, and objective — a record that doesn’t rely on belief or interpretation, but on physical evidence left behind by our ancient ancestors. A fresh chapter of that record has just been described in a new open-access paper in Nature Communications, authored by an international team of palaeoanthropologists led by Professor David R. Braun of the Center for the Advanced Study of Human Paleobiology at George Washington University, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

By comparison, the origins narrative found in Genesis reflects the worldview and assumptions of people who believed the Earth was small, flat, and covered by a solid dome. It is astonishing that, even today, some treat that ancient cosmology as a more reliable account of human history than the rich and expanding fossil and archaeological record in Africa. Yet such individuals continue to seek influence over policy, law, morality, and social institutions, grounding their authority not in evidence, but in pre-scientific tradition — a worldview formed long before the wheel, let alone modern science.

Deciphering the mechanisms of genome size evolution - Current events - University of Barcelona

For years, creationists have confidently assured anyone who’ll listen that evolution can’t possibly work, because losing genetic material is always disastrous — rather like claiming a book can’t be edited without collapsing into meaningless gibberish. Yet nature has an unhelpful habit of ignoring such pronouncements and getting on with things regardless. And now, a tiny spider living quietly in the Canary Islands has delivered another inconvenient data point: it’s been shedding DNA at a remarkable rate, and doing perfectly well in the process.

Researchers led by Julio Rozas and Sara Guirao, from the Faculty of Biology and the Biodiversity Research Institute (IRBio) at the University of Barcelona, have shown that a spider endemic to the Canary Islands has lost almost half its genome in only a few million years.

The spider, Dysdera tilosensis, is a close relative of the mainland species D. catalonica and the familiar British woodlouse-hunter, D. crocata, yet is morphologically almost identical to both.

The findings have been published in the journal Molecular Biology & Evolution.

This discovery runs counter to a general pattern in evolutionary biology, in which adaptation to oceanic island environments often involves increases in genome size. Rather than undermining evolution, this unexpected result enriches the scientific debate over how and why genome size changes during evolution.

It also raises awkward questions for creationist dogma. Why would an intelligent designer equip spiders with almost twice as much genetic material as they actually need? And how would one distinguish such closely related species or show a transition from one to the other in the fossil record, if genome size — the key difference — leaves no trace in fossils?

Ancient fish was hiding in plain sight hundreds of years after its believed extinction, study shows - Taylor & Francis Newsroom

A recent re-examination of museum coelacanth fossils has shown that there was more than one taxon in the Late Triassic and that, where we believed there were just four specimens, there are actually more than fifty. These fossils were hiding in plain sight, mis-identified for decades in collections across Britain. This significantly expands the known diversity of coelacanths at that time and neatly illustrates how science continually refines and improves its understanding as new evidence and careful re-analysis emerge.

Coelacanths have long been a favourite talking-point for creationists, who seized on the 1938 discovery of living Latimeria — a lineage once known only from the fossil record and thought extinct — as supposed proof that evolution had somehow stalled. Because the modern species still carries the name “coelacanth”, they leap to the assumption that the fish has remained unchanged for over 200 million years, and therefore evolution must be false. I have even seen creationists claim that if coelacanths have “not evolved” in all that time, the Earth must therefore be only a few thousand years old. It’s an extraordinary logical contortion — and one born of misunderstanding both biology and evidence.

In reality, the modern coelacanth is not the same species as the ancient Triassic forms, nor is evolutionary change required to be dramatic or constant for every lineage. Species can remain broadly similar when their ecological niche remains stable — a concept perfectly consistent with evolutionary theory. What this study demonstrates, once again, is the iterative, self-correcting nature of science: questions are never closed, evidence is always open to re-examination, and conclusions adapt as new data emerges.

Unintelligent Design - Flatworms Can Regenerate Body Parts - So Why Can't Humans?

The planarian Schmidtea mediterranea

Schmidtea mediterranea

New research shows a tiny, regenerative worm could change our understanding of healing Stowers Institute for Medical Research

Researchers at the Stowers Institute for Medical Research have uncovered new details explaining how the planarian flatworm, Schmidtea mediterranea, can regenerate not just a missing body part, but an entire organism from a tiny tissue fragment. Their findings have just been published in Cell Reports and represent a major advance in our understanding of regeneration at the cellular and genetic level.

This little worm continues to surprise scientists. Remove its head? It grows a new one. Slice it into pieces? Each piece becomes a complete worm. Such astonishing powers naturally prompt two very different kinds of questions – one scientific, one theological.

If one temporarily accepts creationist premises for the sake of argument, we are forced into a series of uncomfortable and contradictory conclusions.

Why would a supposedly omniscient, omnipotent, and omnibenevolent designer grant a humble flatworm the ability to regenerate an entire body, yet deny this life-saving ability to humans and virtually all other organisms? If this designer could abolish suffering, disease, and limb loss – and knowingly chose not to – what does that imply about its nature?

Creationists are left defending a worldview in which their designer appears either: unwilling to prevent suffering; unable to create beneficial traits consistently; or deliberately designing suffering into its creation. None of these options are theologically tidy – and they certainly do not align with the claim of a universally benevolent designer. The creationist framework produces contradictions, apologetics acrobatics, and moral dilemmas rather than answers.

By contrast, when we ask the evolutionary question – “How did this ability evolve?” – the picture becomes coherent.

Planarians have followed a unique evolutionary trajectory in which extreme regeneration conferred a significant survival advantage. Natural selection acted on stem-cell behaviour, gene regulation, and patterning networks over deep time, refining a mechanism that happens to be far beyond the needs of most other species.

Other organisms have regenerative abilities too – salamanders, zebrafish, sea stars, even humans to a limited extent – but the selective pressures and biological constraints differed. Regeneration is complex, energetically costly, and evolution works from what already exists. Most lineages simply did not follow that path. To borrow Michael Behe’s favourite term, planarian regeneration may appear “irreducibly complex” – and yet, as usual, complexity proves to be a testament to gradual evolutionary refinement, not evidence for supernatural assembly.

Great Apes

Humans evolved fastest amongst the apes | UCL News - UCL – University College London

A newly published paper in Proceedings of the Royal Society B by researchers from University College London (UCL) shows that the human skull evolved relatively rapidly compared to that of other apes. The evolutionary changes involve modifications in the size and shape of the facial and cranial bones.

This serves as a reminder of just how artificial and functionally useless the creationist concept of a “kind” is. It should also show creationists the fallacy of the frequent claim that biologists are abandoning the Theory of Evolution, since this paper discusses the results of evolution, not some infantile notion of magical intervention by an unevidenced supernatural entity.

Creationists are quite content to regard all cats—from domestic tabbies to tigers—as belonging to the same “kind”, even though the main difference between them lies in the size of their skeletons. Yet they balk at the idea that humans and the great apes could belong to the same “kind”, despite the fact that the key distinctions between us and them are also differences in size and proportion—most notably in the bones of the skull.

But then, “kind” is precisely the sort of term creationists favour because it has no fixed definition and can be expanded or contracted to suit whatever argument they are trying to make. The only consistent rule seems to be that whatever constitutes a “kind”, it must always exclude humans. This sometimes leads to the absurdity of defining an “animal kind” and a separate “human kind”.

The UCL team suggest that the rapid evolution of the human skull can be explained by the considerable advantage conferred by a larger brain and advanced cognitive abilities.

Our complex cognition allows us to communicate abstract ideas through both words and gestures—what we call “body language”—much of which depends on facial expression. A flat, forward-facing face enhances our ability to convey and interpret these subtle cues. As social animals, we identify acquaintances and strangers by their faces; we watch the faces of those who speak to us; and we instinctively read emotions such as pleasure, anger, confusion, or distress in their expressions.

In short, it is our large brain and expressive face that make us human — not the addition of new organs or limbs, as creationists often insist marks a change above the genus level, but rather differences in the size and shape of the bones of the skull. Given the close similarity of our genomes to those of other apes, these differences arise not from the amount of genetic information, but from the way that information is regulated during embryonic development.

Urban civilization rose in Southern Mesopotamia on the back of tides – Woods Hole Oceanographic Institution

Researchers at Woods Hole Oceanographic Institution have shown, in a paper just published in PLOS ONE, that the rise of Sumerian civilization in Mesopotamia was strongly influenced by the dynamic interplay of tides, rivers, and sedimentation at the head of the Arabian Gulf. In doing so, they remind us just how parochial and derivative the culture that produced the origin myths in Genesis really was.

According to Genesis — which places the Middle East, and the Hebrews in particular, at the centre of everything — humans were created fully formed, without ancestry, in a ready-made Bronze Age civilisation.

Within just five generations of a supposed genocidal global flood that allegedly reset life on Earth, eight survivors are said to have produced a population large and skilled enough to embark on a massive civil engineering project: building a tower up to Heaven. In this worldview, Heaven lay just above the clouds over the Middle East, on a flat Earth watched over by a creator god who could apparently be taken by surprise.

Meanwhile, several other ancient civilisations were continuing uninterrupted, apparently unknown to the author of Genesis — despite the fact that some of the stories in Genesis are clearly derived from older Mesopotamian and Egyptian myths. Both the genocidal flood myth and the Tower of Babel narrative draw directly on Mesopotamian sources: the flood from the Epic of Gilgamesh, and the tower itself from the Great Ziggurat at Ur.

What the Genesis myths fail to acknowledge is the fundamental role of geological and environmental change in shaping human civilisation. The authors of these myths believed they lived in an unchanging world, created especially for them by a perfect god. There is no hint of plate tectonics shifting continents, no awareness that volcanic gases can alter climates, or that major rivers can change course or silt up. Yet such processes could and did disrupt the regular flooding on which early agriculture depended. Silting and delta formation could leave once-coastal communities stranded inland, while blocking the twice-daily tidal ebb and flow that once reached deep upriver.

Refuting Creationism - A Tiny Fossil From New Zealand Is Another Huge Problem For Creationism

Apart from the fact that this fossil is a million years old, there is nothing in this discovery that creationists will struggle to dismiss with one of their well-worn stock phrases — “It was just a bird ‘kind’,” “It wasn’t transitional,” and so on. This is despite the fact that their Bible is remarkably vague about how many bird ‘kinds’ there were, includes bats as birds, and says absolutely nothing about anything outside a few square miles of the Middle East.

And of course, the date — like the entire fossil record — will be casually brushed aside as forged, fabricated, or “wrongly dated using proven false carbon dating” [sic].

But to anyone who actually values evidence and truth, and is not intent on proving their strength by clinging to demonstrably false beliefs in defiance of all contrary evidence, this find is genuinely fascinating. It provides strong evidence that the bowerbirds, today confined to Australia and New Guinea, were once far more widespread. This conclusion is based on the fact that the fossil was discovered in New Zealand. It is also suggested that climate change may have brought about its extinction in New Zealand and driven the bowerbirds' range back to its present distribution.

The discovery is reported in the journal Historical Biology by researchers from University of Cambridge, University of Otago, and Museum of New Zealand Te Papa Tongarewa. A [news release from the University of Otago]() explains the significance of the find and four of the authors have also written an article about the find in The Conversation.

Natural Japanese and Taiwanese Hinoki Cypresses Genetically Differentiated 1 Million Years Ago | Research News - University of Tsukuba

Japanese plant geneticists, led by scientists from University of Tsukuba, have shown that the Japanese and Taiwanese Hinoki cypresses began to diverge around one million years ago, following the destruction of a land bridge that once connected Taiwan to the Japanese archipelago.

This is a textbook example of allopatric speciation, in which an isolated population diverges from its parent population through a combination of founder effects, genetic drift, and natural selection in response to different environmental pressures.

The now-vanished land bridge once linked Taiwan to the southern Japanese island of Kyushu. Its remnants form the Ryukyu Arc — a chain of small islands marking the south-eastern boundary of the South China Sea.

Faced with such clear evidence of speciation, creationists typically resort to a familiar tactic: redefining evolution into a straw man. They insist that “evolution” means one species turning in a single event into something utterly unrelated — for instance, that these cypresses should transform into daisies, cabbages, mammals, or birds. If such an absurd event ever occurred, it would in fact falsify evolutionary theory and throw the entire fields of biology and taxonomy into chaos. This is the standard creationist tactic on social media: misrepresent science, then demand that science defend the misrepresentation, and claim victory when it doesn’t.

The reality remains, however, that the divergence of these related species of cypress — and the fact that this divergence can be correlated precisely with geological change — stands as powerful evidence for Darwinian evolution. Charles Darwin knew nothing of genes, alleles, or genetic drift, yet his description of descent with modification through inherited traits is elegantly confirmed here by modern genetics and biogeography. The genus Chamaecyparis — commonly known as the false cypresses — is an evolutionarily interesting group of conifers in the cypress family Cupressaceae. Their distribution and divergence provide a good illustration of how geological change, climate oscillations, and geographic isolation have shaped the evolution of temperate conifers.
