Refuting Creationism - How Dogs Spread Across The Americas - Then Survived The Legendary Biblical Global Flood
Ancient DNA reveals new clues about the incredible journey of dogs in the Americas | University of Oxford
According to the Bible, all living things outside Noah’s Ark were destroyed once Noah, his family, and his chosen animals were safely sealed inside (Genesis 7:4). This supposedly happened around 4,000 years ago, according to the biblical narrative — which creationists firmly believe to be inerrant history.
The snag is, the evidence simply doesn’t support that timeline—or a global flood involving mass extinction by drowning. Not only would such a flood have left a distinctive global deposit of sediment, containing a chaotic mix of ancient and modern animal and plant species from disconnected continents, but it would also have erased all archaeological traces of earlier civilisations and palaeontological evidence of past life. In effect, it would have reset the clocks of both archaeology and palaeontology to start around 4,000 years ago.
Unfortunately for biblical literalists, that’s not what we see. The predicted tell-tale layer of silt is conspicuously absent. Instead, both archaeology and palaeontology reveal a pattern of uninterrupted occupation of the planet by animals and humans stretching back tens of thousands—and, in the case of animal and plant species, hundreds of millions—of years. For anatomically modern humans, there is a consistent archaeological record documenting their spread across all land masses (except Antarctica), during which they domesticated animals such as dogs, which migrated alongside them.
One example of this pattern — the migration of domestic dogs with humans into the Americas between 7,000 and 5,000 years ago — has just been published in Proceedings of the Royal Society B, by an international team of scientists led by Dr Aurélie Manin from the School of Archaeology at the University of Oxford. They have shown that all South American dogs prior to the arrival of Europeans, trace their ancestry back to a single female. One strain — the Mexican Chihuahua - still shows evidence of that ancestry.

Refuting Creationism - How We Know The Bible Was Made Up By Scientifically-Illiterate People

The Bible contains no scientific insights or understanding beyond what would have been known to Bronze Age pastoralists—what Christopher Hitchens aptly described as the "fearful infancy of our species." Their knowledge was naturally constrained by the absence of scientific instruments, a lack of understanding of the planet's history, and a worldview shaped by tribal dogma and magical thinking.
Had the Bible truly been written or inspired by the deity it describes — as a vital message to humanity from the creator of the universe — one might reasonably expect it to contain some revelations unknown to its time. Yet it offers nothing by way of evidence to support such a claim. There is no mention of germ theory, no understanding of cells or cellular life, no grasp of atoms, electricity, or metabolic processes like photosynthesis and respiration. All living things are described as strictly male or female, with no recognition of genetics, hermaphroditism or parthenogenesis — except for a single, supposedly miraculous human birth of a genetically impossible male child. In short, the text contains nothing that was not already known or assumed until the development of tools like the microscope and telescope, and much of it was clearly and demonstrably wrong.
The Bible’s authors were storytellers, not scientists. Their goal was not to challenge the cultural assumptions of their time but to frame them within a compelling narrative.
Because religions are not founded on tested hypotheses or objective facts but rather on the best guesses of uninformed people, any alignment with modern scientific understanding is coincidental, not predictive. For example, the biblical phrase *"Let there be light"* is sometimes interpreted as metaphorically reflecting the early high-energy state of the universe following the Big Bang. But there is no indication that the authors understood photons, particle physics, or the quantum nature of space-time. Nor did they suggest that the universe originated nearly 14 billion years ago in a quantum fluctuation of a non-zero energy field.
Recent discoveries illustrate just how far modern science has advanced beyond anything conceivable to ancient authors. For instance, an international team of scientists has recently found evidence suggesting the existence of heavy particles during the universe's first microseconds—particles that influenced the behaviour of other matter. This discovery, utterly incomprehensible to a Bronze Age worldview, is detailed in a peer-reviewed article published in Physics Reports.

Refuting Creationism - A 600-Million-Year-Old Common Ancestor of Cnidarians and Bilaterians.
Bodybuilding in Ancient Times: How the Sea Anemone Got Its Back
Childish creationist claims of a young Earth, the spontaneous magical generation of all living organisms without ancestry, and the supposed absence of evidence for the evolution of life from a common ancestor have taken another blow with the publication of compelling new research that refutes these basic creationist dogmas.
An open access paper published in Science Advances describes a candidate ancestral mechanism for establishing bilaterality — symmetry along a central axis — in both bilaterians (animals with bilateral symmetry) and the sea anemone Nematostella. The study, conducted by four researchers from the Department of Neurosciences and Developmental Biology at the University of Vienna, provides crucial insights into the deep evolutionary origins of body plan organisation.
It is also clear from both the paper and the researchers' explanation in a University of Vienna press release that they regard the Theory of Evolution as essential to interpreting their findings. Their discovery fits squarely within the evolutionary framework and aligns with the established timeline for the diversification of animal life from a common ancestor.
What Is Bilateral Symmetry? Bilateral symmetry is a body plan in which an organism can be divided into roughly mirror-image halves along a single plane—from head to tail. Most animals, including humans, insects, and vertebrates, display this type of symmetry.
Why Is It Evolutionarily Significant?
- Directional Movement: Bilateral symmetry enables streamlined, forward-facing movement—ideal for seeking food, mates, and avoiding danger.
- Cephalisation: This symmetry is often associated with the development of a head region where sensory organs and the brain concentrate—an evolutionary advantage for processing information efficiently.
- Complexity and Specialisation: It allowed for greater internal organisation and the evolution of specialised body systems (e.g., digestive, nervous, and circulatory).
Evolutionary Milestone
Bilateral symmetry is thought to have evolved over 600 million years ago in a common ancestor of all bilaterians. This innovation marked a major turning point in the history of life, leading to the vast diversity of animal forms we see today.
Bodybuilding in Ancient Times: How the Sea Anemone Got Its Back
New insights into the evolution of the back-belly-axis.
A new study from the University of Vienna reveals that sea anemones use a molecular mechanism known from bilaterian animals to form their back-to-belly body axis. This mechanism ("BMP shuttling") enables cells to organize themselves during development by interpreting signaling gradients. The findings, published in Science Advances, suggest that this system evolved much earlier than previously assumed and was already present in the common ancestor of cnidarians and bilaterians.
Most animals exhibit bilateral symmetry—a body plan with a head and tail, a back and belly, and left and right sides. This body organization characterizes the vast group known as Bilateria, which includes animals as diverse as vertebrates, insects, molluscs and worms. In contrast, cnidarians, such as jellyfish and sea anemones, are traditionally described as radially symmetric, and indeed jellyfish are. However, the situation is different is the sea anemones: despite superficial radiality, they are bilaterally symmetric – first at the level of gene expression in the embryo and later also anatomically as adults. This raises a fundamental evolutionary question: did bilateral symmetry arise in the common ancestor of Bilateria and Cnidaria, or did it evolve independently in multiple animal lineages? Researchers at the University of Vienna have addressed this question by investigating whether a key developmental mechanism called BMP shuttling is already present in cnidarians.
Shuttling for development
In bilaterian animals, the back-to-belly axis is patterned by a signaling system involving Bone Morphogenetic Proteins (BMPs) and their inhibitor Chordin. BMPs act as molecular messengers, telling embryonic cells where they are and what kind of tissue they should become. In bilaterian embryos, Chordin binds BMPs and blocks their activity in a process called "local Inhibition". At the same time, in some but not all bilaterian embryonic models, Chordin can also transport bound BMPs to other regions in the embryo, where they are released again – a mechanism known as "BMP shuttling". Animals as evolutionary distant as sea urchins, flies and frogs use BMP shuttling, however, until now it was unclear whether they all evolved shuttling independently or inherited it from their last common ancestor some 600 million years ago. Both, local inhibition and BMP shuttling, create a gradient of BMP activity across the embryo. Cells in the early embryo detect this gradient and adopt different fates depending on BMP levels. For example, in vertebrates, the central nervous system forms where BMP signaling is lowest, kidneys will develop at intermediate BMP signaling levels, and the skin of the belly will form in the area of maximum BMP signaling. This way, the body's layout from back to belly is established. To find out whether BMP shuttling by Chordin represents an ancestral mechanism for patterning the back to belly axis, the researchers had to look at bilaterally symmetric animals outside Bilateria – the sea anemones.
An Ancient Blueprint
To test whether sea anemones use Chordin as a local inhibitor or as a shuttle, the researchers first blocked Chordin production in the embryos of the model sea anemone Nematostella vectensis. In Nematostella, unlike in Bilateria, BMP signaling requires the presence of Chordin, so, without Chordin, BMP signaling ceased and the formation of the second body axis failed. Chordin was then reintroduced into a small part of the embryo to see if it could restore axis formation. BMP signaling resumed—but it was unclear whether this was because Chordin simply blocked BMPs locally, allowing a gradient to form from existing BMP sources, or because it actively transported BMPs to distant parts of the embryo, shaping the gradient more directly. To answer this, two versions of Chordin were tested—one membrane-bound and immobile, the other diffusible. If Chordin acted as a local inhibitor, both, the immobile and the diffusible Chordin would restore BMP signaling on the side of the embryo opposite to the Chordin producing cells. However, only diffusible Chordin can act as a BMP shuttle. The results were clear: Only the diffusible form was able to restore BMP signaling at a distance from its source, demonstrating that Chordin acts as a BMP shuttle in sea anemones—just as it does in flies and frogs.
A shared strategy across over 600 million years of evolution?
The presence of BMP shuttling in both cnidarians and bilaterians suggests that this molecular mechanism predates their evolutionary divergence some 600-700 million years ago.
Not all Bilateria use Chordin-mediated BMP shuttling, for example, frogs do, but fish don't, however, shuttling seems to pop up over and over again in very distantly related animals making it a good candidate for an ancestral patterning mechanism. The fact that not only bilaterians but also sea anemones use shuttling to shape their body axes, tells us that this mechanism is incredibly ancient. It opens up exciting possibilities for rethinking how body plans evolved in early animals.

Our new study showed that.

This discovery poses a significant problem for creationist claims because it provides clear molecular and developmental evidence for a shared evolutionary origin between animals with bilateral symmetry and simpler organisms like sea anemones, which lack such symmetry as adults. The fact that the genetic and developmental mechanisms for establishing a "back" or body axis predate the emergence of bilaterally symmetrical animals suggests that these features evolved gradually through modification of existing biological systems—not through sudden, miraculous creation.Abstract Bone morphogenetic protein (BMP) signaling patterns secondary body axes throughout Bilateria and in the bilaterally symmetric corals and sea anemones. Chordin-mediated “shuttling” of BMP ligands is responsible for the BMP signaling gradient formation in many bilaterians and, possibly, also in the sea anemone Nematostella, making BMP shuttling a candidate ancestral mechanism for generating bilaterality. However, Nematostella Chordin might be a local inhibitor of BMP rather than a shuttle. To choose between these options, we tested whether extracellular mobility of Chordin, a hallmark of shuttling but dispensable for local inhibition, is required for patterning in Nematostella. By generating localized Chordin sources in the Chordin morphant background, we showed that mobile Chordin is necessary and sufficient to establish a peak of BMP signaling opposite to Chordin source. These results provide evidence for BMP shuttling in a bilaterally symmetric cnidarian and suggest that BMP shuttling may have been functional in the potentially bilaterally symmetric cnidarian-bilaterian ancestor.
INTRODUCTION
Bone morphogenetic protein (BMP) signaling acts in secondary body axis patterning across Bilateria, and its functions as morphogen have been studied in diverse animal species (1, 2). The mechanisms of the BMP-dependent axial patterning are similar between arthropods and vertebrates, indicative of the shared origin of the secondary, dorsoventral axis in protostome and deuterostome Bilateria, a notion strengthened once broader phylogenetic sampling became available (2–7). Intriguingly, the same mechanisms appear to regulate the secondary axis patterning in the bilaterally symmetric cnidarian Nematostella vectensis, indicating that a BMP-dependent secondary body axis may have evolved before the evolutionary split of Cnidaria and Bilateria [(8, 9), reviewed in (1, 10)]. However, a scenario in which BMP-mediated secondary axes evolved convergently in Bilateria and bilaterally symmetric Cnidaria is also possible (2).
BMPs are secreted signaling proteins of the transforming growth factor–β superfamily frequently acting as heterodimers (11–13). Signaling through the BMP receptor complex (Fig. 1A) results in phosphorylation and nuclear accumulation of the transcriptional effector SMAD1/5, which regulates the expression of many crucial developmental transcription factors and signaling pathway components [(14–18), reviewed in (19, 20)]. BMP signaling is tightly controlled by a plethora of intracellular (14, 21) and extracellular regulators (22–29) of which Chordin (= short gastrulation in insects) is, arguably, the most famous one. Like many other secreted BMP antagonists, Chordin binds BMP ligands, blocks the interaction with their receptor, and thereby inhibits BMP signaling (30). However, Chordin can also have pro-BMP effects and promotes long-range activation of BMP signaling in Drosophila, Xenopus, sea urchins, and in the sea anemone Nematostella (7, 31–34). The phylogenetic distribution of Chordin and two central BMP ligands, BMP2/4 and BMP5-8, and their importance for the secondary axis patterning across phyla suggests that, during early animal evolution, these molecules may have represented the minimum requirement for the formation of the bilaterally symmetric body plan (2, 10). However, to evaluate such a possibility, we need to understand the “mode of action” of BMPs and Chordin outside Bilateria, and our model, the sea anemone Nematostella, allows exactly that.
Fig. 1. Possible modes of action of BMP signaling during axial patterning in Nematostella.
(A) BMP signaling pathway. BMP dimers bind the heterotetrameric receptor complex, resulting in the phosphorylation of SMAD1/5. pSMAD1/5 forms a complex with the Co-Smad SMAD4, which regulates transcription in the nucleus. Chordin binds BMPs preventing them from activating the receptor complex. Metalloproteases like Tolloid and BMP-1 cleave Chordin and release BMP ligands from the inhibitory complex in Bilateria. (B) Expression domains of BMPs and BMP antagonists in an early Nematostella larva. Oral view corresponds to the optical section indicated with grey dashed line on the lateral view. Pink circles show the nuclear pSMAD1/5 gradient. (C) The shuttling model suggests that in Nematostella, a mobile BMP-Chordin complex transports BMPs through the embryo. Receptor binding is inhibited in cells close to the Chordin source due to high concentrations of Chordin. On the opposite side of the directive axis, BMPs bind their receptors and activate signaling upon release from Chordin. Tolloid might be involved in the cleavage of Chordin and release of BMPs from the complex with Chordin also in Nematostella. (D) In the local inhibition model, Nematostella Chordin acts locally to inhibit BMP signaling and promote the production of BMP2/4 and BMP5-8 mRNA. Chordin mobility is not required for asymmetric BMP signaling.
BMP signaling in Nematostella becomes detectable during early gastrula stage in a radially symmetric domain: The phosphorylated form of the BMP signaling effector SMAD1/5 (pSMAD1/5) is detected in the nuclei around the blastopore (14, 35). Shortly after the onset of BMP activity, the radial symmetry of the embryo breaks, establishing the secondary, “directive” body axis with minimum BMP signaling intensity detectable on the side of BMP2/4, BMP5-8, and Chordin expression and maximum BMP signaling on the side opposite to it (Fig. 1B) (14, 34, 35). The symmetry break occurs despite the fact that mRNAs of the type I BMP receptors Alk2 and Alk3/6 and the type II receptor BMPRII are maternally deposited (36) and remain weakly and ubiquitously expressed in the embryo (fig. S1) gradually developing a slight bias toward the “high pSMAD1/5” side of the directive axis by early planula stage (14). BMP2/4 and BMP5-8 are co-expressed in the late gastrula/early planula, and both these ligands are crucial for BMP signaling and directive axis patterning because knockdown of either ligand abolishes pSMAD1/5 immunoreactivity and completely radializes the embryo (34). Individual knockdowns of either BMP2/4 or BMP5-8 result in a strong up-regulation of transcription of both BMP2/4 and BMP5-8 in a radially symmetric domain showing that both these genes are negatively controlled by BMP signaling. Despite transcriptional up-regulation of BMP2/4 in BMP5-8 morphants and BMP5-8 in the BMP2/4 morphants, no nuclear pSMAD1/5 is observed in such embryos (9, 34, 35), suggesting that BMP2/4 and BMP5-8 signal as an obligate heterodimer during axial patterning in Nematostella.
The “core” BMPs, BMP2/4 and BMP5-8, are not the only BMP ligands present in the embryo at this stage. GDF5-like (GDF5L) is a BMP ligand expressed on the side of strong BMP signaling (Fig. 1B). GDF5L expression is abolished in the absence of BMP2/4 and BMP5-8, and the role of GDF5L appears to be in steepening the pSMAD1/5 gradient making it a “modulator” BMP (14, 34, 37). The BMP signaling gradient is stable over many (>24) hours during which it patterns the directive axis (9, 14, 34, 35, 37). Considering the short half-life of phosphorylated SMAD1/5 reported in other systems (15, 21), this indicates that long-range transport (~100 μm) of BMP2/4 and BMP5-8 and constant receptor complex activation is necessary to maintain BMP signaling. How it exactly happens that the core BMP ligands, BMP2/4 and BMP5-8, are expressed on one side of the embryo and the peak of BMP signaling activity is on the opposite side is currently unknown.
One possible explanation involves Chordin-mediated shuttling of BMP ligands, described in the dorsoventral patterning in Drosophila and Xenopus (7, 34, 38). In this model, Chordin inhibits BMP function locally, close to the Chordin source cells, but promotes long-range BMP signaling by forming a mobile complex with the BMP dimer, which is released once Chordin is cleaved by the metalloprotease Tolloid. The probability that this BMP dimer will bind its receptors rather than another, yet uncleaved Chordin increases with the distance to the Chordin source (Fig. 1C). In Nematostella, the shuttling model was proposed when we found that, unlike in all bilaterian models studied thus far, depletion of Chordin results in the loss of BMP signaling rather than in its enhancement (34). However, given that, in Nematostella, BMP signaling indirectly represses the transcription of the core BMPs, BMP2/4 and BMP5-8, and activates the transcription of the modulator BMP, GDF5-like (14), an alternative explanation is also possible: In this “local inhibition” scenario, Chordin locally represses BMP signaling enabling BMP2/4 and BMP5-8 production. BMP2/4 and BMP5-8 diffuse into the area of low or no Chordin (i.e., to the GDF5-like side of the directive axis) and bind the receptors there. In this scenario, Chordin knockdown results in a transient de-repression of the BMP2/4/BMP5-8–mediated signaling, which, in turn, leads to the repression of the BMP2/4 and BMP5-8 transcription. Because, in the absence of BMP2/4 and BMP5-8, GDF5-like expression is also lost (9), we may end in a situation when no BMP ligands are produced and no BMP signaling takes place, as it is the case in the Chordin morphant (9, 34). This local inhibition model, in which Chordin acts exclusively as a local repressor of BMP signaling (Fig. 1D), is similar to the situation in zebrafish, where extracellular mobility of Chordin is not required (39–41). Here, we address the role of Chordin in the BMP-dependent axial patterning in the sea anemone Nematostella and test these two alternative models.

Creationism relies on the assertion that complex body plans appeared abruptly, fully formed, and without evolutionary precursors. However, the findings in this study directly contradict that idea. They show that the genetic toolkit required for bilateral body structures was already present in the common ancestor of cnidarians (like sea anemones) and bilaterians and was likely repurposed and elaborated upon over millions of years. This is exactly what evolutionary theory predicts.
Moreover, the study aligns neatly with the established evolutionary timeline based on genetics, developmental biology, and the fossil record. There is no need to invoke supernatural causes or to assume that animals were created independently and without shared ancestry. Instead, the evidence points to deep continuity in the genetic architecture of life—a hallmark of common descent and a major blow to the isolated, one-off acts of creation claimed by young-Earth and Intelligent Design creationists alike.

Refuting Creationism - Co-Evolution of Trees And Mastodons In South America
The disappearance of mastodons still threatens the native forests of South America - Universitat Autònoma de Barcelona - UAB Barcelona

For creationists who claim that life existed in its present form from the very beginning, this revelation is deeply unsettling. The discovery undermines the belief that forest ecosystems were always fully functional without the need for extinct megafauna—those massive mammals were not mere background actors but ecological engineers whose disappearance left communities of fruit‑bearing plants stranded, fragmented, and genetically impoverished.
Most strikingly, nearly 40 % of plant species once reliant on these now‑vanished seed spreaders are currently classified as threatened—up to four times the rate seen in regions still served by extant dispersers like tapirs or monkeys [2]. For creationists, this means that the natural world was far more dynamic—and far more dependent on evolutionary processes over deep time—than their models allow. If entire forests trebled on species interactions across thousands of years, then the simplistic view that everything was created perfectly, all at once, is seriously called into question.
A new study led by the University of O’Higgins, Chile, with key contributions from Institut Català de Paleoecologia Humana i Evolució Social, Centres de Recerca de Catalunya (IPHES-CERCA), demonstrates for the first time—based on direct fossil evidence—that these extinct elephant relatives regularly consumed fruit and were essential allies of many tree species. The researchers have just published their findings in the journal Nature Ecology & Evolution.

Refuting Creationism - A Technologically Advanced Civilisation in the Philippines - 25,000 Years Before 'Creation Week'

It’s shaping up to be another difficult week for creationists. Hot on the heels of news that humans were fighting and killing in northern Italy 7,000 years before the alleged ‘Creation Week’ and ‘The Fall’—events which biblical literalists claim introduced death into the world—comes fresh evidence of a sophisticated maritime culture flourishing in what is now the Philippines 18,000 years before that.
Another significant challenge for the creationist narrative is that, like the skeletal remains found in Italy, this archaeological evidence in the Philippines was not obliterated by the supposed global flood—an essential element of young Earth creationism for which there is no credible supporting evidence.
The discoveries in the Philippines were made by scientists from Ateneo de Manila University, in collaboration with international experts and institutions. Their research reveals early human migration, technological innovation, and long-distance intercultural connections dating back more than 35,000 years. The findings have been published in Archaeological Research in Asia, and are also explained in a news release from Ateneo de Manila University.

Refuting Creationism - Human Conflict And Death - 7,000 Years Before 'Creation Week'
Shanxi Provincial Museum, Taiyuan.
17,000-year-old skeleton reveals earliest evidence of Stone Age ambush and human conflict | Archaeology News Online Magazine
Towards the end of that immensely long pre-Creation Week period of Earth’s history — when 99.9975% of everything had already happened before creationists believe their god made a small, flat Earth with a dome over it in the Middle East, as described in the Bible — humans were already fighting battles in what is now northern Italy. To be precise, this occurred around 7,000 years before 'Creation Week'.
This conclusion comes from the analysis of a 17,000-year-old skeleton belonging to a man aged between 22 and 30, bearing unmistakable injuries caused by flint-tipped projectiles—likely arrows or spears. The skeleton, discovered in 1973 at the Riparo Tagliente rock shelter in the Lessini Mountains of northeastern Italy, only recently revealed its violent past thanks to modern forensic techniques.
The findings, led by bioarchaeologist Vitale Sparacello of the University of Cagliari, were published in the journal Scientific Reports.

Refuting Creationism - Co-Evolution of Humans and Influenza Viruses - Just as the TOE Predicts
In a striking confirmation of evolutionary theory—and a clear rebuttal of several fundamental creationist claims—scientists have demonstrated a close correlation between population-level immunity and the evolution of influenza viruses to evade that immunity. The findings, reported in eLife, align perfectly with predictions made by evolutionary biology: as the immune landscape of a population shifts, so too does the genetic makeup of viruses in an ongoing evolutionary arms race.
Disappointingly for creationists hoping for signs that biomedical science is abandoning evolution in favour of supernatural explanations, there is no such evidence. Nowhere in the study is there a hint that scientists are retreating from evolutionary principles or embracing a non-falsifiable belief system involving mysterious, unexplained entities. On the contrary, the researchers are clear and unequivocal: their results reinforce the view that viral evolution is a dynamic, adaptive process shaped by natural selection in response to host immunity.
Even more troubling for proponents of Intelligent Design (ID) is the unavoidable implication that the viral mutations observed in this study constitute what William A. Dembski calls "complex specified information"—which he argues can only arise through the intervention of an intelligent designer. If one follows that line of reasoning, the logical (if deeply uncomfortable) conclusion is that this designer is actively modifying viruses to undermine the very immune systems it supposedly created to protect us. Such behaviour can hardly be described as intelligent and is incompatible with the benevolent deity so often associated with the Intelligent Design movement.

Malevolent Design - The Sneaky Way TB Keeps On Making Us Sick
Study discovers DNA switch that controls TB growth – and could help unlock its antibiotic resistance secrets | University of Surrey
If you're an omniscient, omnipotent, malevolent designer of parasites — such as the bacterium that causes tuberculosis in humans — then you're hardly going to let a little thing like the immune system (which you supposedly also designed to protect them) or even the development of medical science and antibiotics spoil your fun in causing random suffering, are you? Naturally, you'd equip your creation with mechanisms to overcome these obstacles.
Within the framework of Intelligent Design creationism, that's precisely what this recent discovery should look like — at least to those creationists who don't simply ignore the obvious and pretend it isn't there. Scientists from the Universities of Surrey and Oxford have discovered that Mycobacterium tuberculosis uses a reversible process known as ADP-ribosylation to modify its DNA, controlling both replication and gene expression. This allows the bacterium to remain dormant for extended periods and reactivate when environmental threats, such as immune responses or antibiotics, have passed.
This presents a problem for creationists who insist on believing in a benevolent creator deity and simultaneously hold that features such as irreducible complexity and complex specified information are sure signs of intelligent design—claims promoted by Discovery Institute fellows Michael J. Behe and William A. Dembski. Since Mycobacterium tuberculosis displays these very characteristics, so either it was designed specifically to cause suffering, or those characteristics are not the reliable indicators of divine design that Behe and Dembski claim, and their entire argument collapses.
This discovery was recently published open access in The EMBO Journal, and further details are available in the University of Surrey press release:
How Evolution Works - Co-opting Old Genes For New Functions

One common way creationist apologists attempt to mislead the scientifically uninformed is by claiming that the Laws of Thermodynamics are somehow relevant to the evolution of information within a species' genome. They argue that any increase in genetic information would violate both the Second and Third Laws of Thermodynamics—asserting that increased biological complexity equates to a decrease in entropy (disorder), and that new information is akin to energy and thus cannot increase due to the Law of Conservation.
This argument is fundamentally flawed on several levels but continues to be repeated despite being repeatedly refuted by both biologists and physicists. First, it completely ignores the fact that Earth is not a closed system. The input of energy from the Sun, for example, allows local decreases in entropy (such as in the formation of complex biological structures) while the total entropy of the universe still increases, fully complying with the Second Law. The Third Law, which relates to the entropy of systems at absolute zero, is entirely irrelevant to biological evolution.
Second, the idea that genetic information is conserved like energy is a misrepresentation. Genetic information can and does change in multiple ways through mutation. A mutation can involve the loss of information (e.g. deletion of a DNA segment), a change in information (e.g. substitution of one or more nucleotides), or an increase in information (e.g. insertion of additional sequences, or the movement of transposable elements—“jumping genes”—to new locations in the genome). None of these processes require a change in the total amount of matter or energy; they simply involve the rearrangement of existing molecular components. Any local increase in biological order is offset by energy expenditure elsewhere, typically via the hydrolysis of ATP to ADP and phosphate within metabolic pathways.
Moreover, these objections rest on the false assumption that evolution is about the quantity of information. In reality, it is the function and meaning of genetic information that drives evolutionary change. A sequence of DNA that once encoded a protein with one function can, through mutation and natural selection, take on a new function entirely—a process known as exaptation.
A well-known example is the evolution of the mammalian middle ear bones. In ancestral fish, certain jawbones played a structural role in the jaw joint. Over time, in early synapsids, these bones were repurposed and miniaturised to become part of the auditory system, transmitting sound vibrations from the eardrum to the cochlea.

Malevolent Design - How Creationism's Divine Malevolence is Helping Cholera Win An Arms Race Against A Virus
How cholera bacteria outsmart viruses - EPFL

A striking example of such an evolutionary arms race has just been uncovered by a team from École polytechnique fédérale de Lausanne (EPFL), who found that a notorious strain of cholera possesses a suite of sophisticated immune systems to fend off viral attack. According to ID proponents like William A. Dembski, both this cholera strain and the viruses that infect it should qualify as products of ‘complex, specified information’. Likewise, under Michael J. Behe’s definition, both would be considered ‘irreducibly complex’. By their logic, this makes them the result of intelligent design by a supernatural creator.
In other words, creationism’s designer god has supposedly created viruses that infect the cholera bacterium—then equipped the bacterium with complex machinery to defend itself.
To make matters worse for creationists, this virus-resistant cholera strain was behind a devastating epidemic across Latin America. That is, the designer god not only enabled the bacterium to resist viruses, but in doing so gave it a better chance of surviving to infect and harm humans—using its ‘intelligently designed’, ‘irreducibly complex’ viral defences.
The research is published open access in Nature Microbiology.

Creationism Refuted - Exquisite Fossils From 226 Million Years Before 'Creation Week'

In the realm of palaeontology, few discoveries are as illuminating as those that offer a window into ecosystems long vanished. A recent study published in The Conversation by palaeontologist Rosemary Prevec of Rhodes University, South Africa, unveils such a discovery: an exquisitely preserved fossil site in South Africa's Northern Cape province, dating back 266 million years to the middle Permian period. This site reveals a thriving ecosystem teeming with diverse plant life and a myriad of insect species, providing an unprecedented glimpse into pre-dinosaur terrestrial life.[1]
The significance of this find extends beyond its immediate scientific value; it directly challenges fundamental creationist assertions. By presenting concrete evidence of complex ecosystems existing millions of years before the advent of humans, it undermines the young-Earth creationist timeline that posits a 6,000 to 10,000-year-old Earth. The detailed stratigraphy and radiometric dating techniques employed corroborate the Earth's ancient history, aligning with the broader scientific consensus on geological and biological evolution.
Moreover, the discovery underscores the continuity and gradual progression of life forms, countering the notion of sudden creation. The intricate details preserved in these fossils—ranging from delicate insect wings to diverse plant structures—highlight the complexity and diversity of life well before the emergence of humans. Such findings reinforce the evolutionary narrative of life's development over hundreds of millions of years, offering tangible evidence against creationist models that reject evolutionary theory.

Unintelligent Design - Why Your Toothache Has Ancient Origins - In Your Ancestral Fish

Have you ever taken a mouthful of ice cream or cold water, only to be rewarded with a sudden, stabbing pain in your teeth? It vanishes in a few seconds, but for that brief moment, it’s excruciating.
You might wonder what kind of intelligent designer would produce such a feature—one that serves no apparent purpose other than to make you suffer. The answer, of course, is that it wasn’t designed at all.
Like so much else about the human body, the sensitivity of our teeth is the product of evolution—a long, meandering process shaped not by foresight or intent, but by whatever natural selection happened to favour at the time. That over-sensitive layer of dentine beneath the enamel traces its origins back to ancient jawless fish, whose bony body armour included sensory structures capable of detecting changes in their environment. These structures were crucial for survival and heavily favoured by selection.
As evolution repurposed this structure over millions of years—eventually becoming part of our teeth—there was no strong selection pressure to reduce its sensitivity. In the aquatic world of those primitive fish, a keen sensory system might have meant the difference between life and death. In modern humans, however, it serves no meaningful function. A momentary sting when we drink something cold doesn’t affect our survival or reproductive success, so we’re left with a redundant sensory feature that occasionally causes pain.
If ever there were a perfect illustration of how evolution works—and why no intelligence is required—this is it. Unless, of course, you believe the designer in question is a malevolent deity with a particular interest in toothaches.
The discovery of this direct connection with our remote ancestral past was made by researchers at the University of Chicago who have just published their findings, open access in Science.

Creationism Refuted - New Finding Shows That Reptiles Were Around At Least 350 million Years Before 'Creation Week'
Fossil tracks revise march of early life on Earth – News
In a paper that creationists will no doubt feel compelled to ignore, misrepresent, or dismiss, scientists report the discovery of reptile tracks in 350-million-year-old Australian rocks. This remarkable find pushes back the earliest known trace of reptiles by some 40 million years.
For mainstream science, this discovery provides further clarification of the timeline for the evolution of terrestrial tetrapods. However, for creationists—who continue to compress Earth's 3.8-billion-year history into a mere 6,000 to 10,000 years in order to preserve a literal interpretation of Genesis—it presents yet another challenge to their beliefs.
It is the kind of evidence that science routinely uncovers, forcing creationists into ever more creative contortions to avoid confronting the reality of evolution.
The discovery was made by Professor John Long of Flinders University and colleagues, who have detailed their findings and their significance in a Flinders University press release. Additionally, Professor Long, together with Grzegorz Niedzwiedzki and Professor Per Ahlberg of Uppsala University, Sweden, has published an open-access article discussing the research in The Conversation.

Refuting CReationism - A Transitional Salmon Ancestor from 73 Million Years Before 'Creation Week'
New ancient fish species earliest known salmon ancestor | UAF news and information

It’s no surprise then that this is just another such paper. It reports on the discovery of fossil ancestors of modern salmon which lived in Alaskan rivers, 70 million years ago, pushing back the earliest ancestral salmon so far discovered by 20 million years.
The discovery was made by palaeontologists from the University of Alaska, Fairbanks led by Patrick Druckenmiller, director of the University of Alaska Museum of the North. They have just published their findings, open access, in the journal, Papers in Palaeontology. Their work is also explained in a University of Alaska, Fairbanks, news item:

Malevolent Designer - How The Influenza Virus Appears To Be Intelligently Designed to Make Us Sick

In their attempts to pass creationism off as legitimate science, Discovery Institute fellows William A. Dembski and Michael J. Behe have unwittingly undermined their own case. Their arguments—largely based on a classic god-of-the-gaps fallacy and a false dichotomy—can just as easily be turned against the very idea that their supposed intelligent designer is the God of the Christian Bible.
While they stop short of making that claim explicitly, the infamous Wedge Document [1.1], which outlines the political aims and strategy of the Discovery Institute, leaves no doubt: their ultimate goal is a fundamentalist Christian theocracy governed by so-called "Christian principles" and that selling the idea that 'Intelligent Design' creationism is real science, is a fundamental aspect of that strategy because it would enable them to teach creationism to children at taxpayers' expense, under the guise of real science.
And yet, even within their own paradigm, the evidence points not to a benevolent deity but to something far more disturbing.
Take, for example, recent research from the Helmholtz Centre for Infection Research, which offers a striking illustration of what Dembski might call "complex specified information" and what Behe might regard as "irreducible complexity". The study reveals how the influenza virus is 'designed'—if one accepts their terminology—with remarkable sophistication to circumvent our defences and invade human cells. Ironically, these very defences are what the same creationists insist were intelligently designed to protect us—against, among other things, intelligently designed viruses. We are left, according to this worldview, with the absurd spectacle of a designer who engineers both the pathogens and the immune system meant to defend us from them—a system that, demonstrably, does not always work.
And this is held up as evidence of a supreme intelligence!
Far from supporting creationist claims, these findings align far more convincingly with what we would expect from a blind, indifferent process of evolution—one that requires no designer at all. Once again, creationists are faced with an uncomfortable dilemma: either accept the notion of a malevolent and inept designer or acknowledge the explanatory power of natural selection and evolutionary biology.
Refuting Creationism - What T. Rex's Ancestors Were Doing More Than 70 Million Years Before 'Creation Week'.
T. rex’s direct ancestor crossed from Asia to North America | UCL News - UCL – University College London

During that immense period, something remarkable was happening: a distant ancestor of Tyrannosaurus rex, destined to become one of the most formidable land predators the planet has ever seen, was making its way across a land bridge from Asia into North America.
That’s the conclusion of a new study led by researchers at University College London (UCL), recently published in Royal Society Open Science. The team found that this transcontinental migration—via the Beringian land bridge over 70 million years ago—marked a key moment in the evolution of tyrannosaurids. They also noted a rapid increase in body size that appears to have coincided with a global cooling event following a climatic peak around 92 million years ago. The study was a collaboration between scientists from UCL and the universities of Oxford, Pittsburgh, Aberdeen, Arizona, Anglia Ruskin, Oklahoma, and Wyoming.

Refuting Creationism - Why Gaps In The Fossil Record Are To Be Expected, Naturally
registered at the Museum d’histoire naturelle de Marrakech.
Why did some ancient animals fossilize while others vanished?
One of creationism’s favourite fallacies is the claim that gaps in the fossil record disprove evolution, based on a misrepresentation of something Charles Darwin wrote. According to this argument, Darwin supposedly insisted there should be a complete and continuous series of transitional fossils and admitted that any gaps would be fatal to his theory.
As with many creationist arguments, this is a distortion of both Darwin’s actual words and how science works. It reflects a peculiar misunderstanding of science as a belief system centred on the writings of historical figures — Darwin, in this case, cast as the ‘prophet’ of ‘evolutionism’. The implication is that by discrediting Darwin personally, or selectively quoting his early uncertainties, one can somehow bring down an entire field of modern science built on nearly two centuries of accumulating evidence.
The tactic ignores the fact that Darwin's style was to introduce the reader to a seemingly unaswerable problem, or potential difficulty for his theory, before explaining how his theory of evolution by natural selection provided an answer.
But why would any reasonable person expect the fossil record to preserve every generation of every species, in every habitat, across hundreds of millions of years—and for those remains to be conveniently accessible to palaeontologists today? The idea that scientists expect such completeness betrays a deep scientific illiteracy. Fossilisation is an exceptionally rare process requiring very specific conditions. There are many reasons why an organism is unlikely to fossilise, and relatively few that make fossilisation even possible.

Refuting Creationism - Giant Fast-Running Croccodiles In the Caribbean - 11 Million Years Before 'Creation Week'

Six million years before biblical literalist creationists assert Earth and all living creatures were created ex nihilo, giant long-legged, crocodile-like predators known as sebecids were hunting their prey on Caribbean islands. Remarkably, these creatures persisted long after similar species had vanished from South America, where sebecids had become apex predators following the extinction of the dinosaurs 66 million years ago.
Although sebecids went extinct on mainland South America about 11 million years ago, new evidence from Caribbean fossil records shows they survived considerably longer on islands, continuing as apex predators. This finding comes from recent research conducted by a team of palaeontologists from the Florida Museum, who have been compiling evidence over the past three decades. The team's detailed findings have now been published in the journal Proceedings of the Royal Society B. Further insights and context are available in an accompanying Florida Museum news article.

Refuting Creationism - How Plate Tectonics Allowed The Interchange of Species, Including Human Ancestors, Between Africa and Asia
How Activity in Earth’s Mantle Led the Ancient Ancestors of Elephants, Giraffes, and Humans into Asia and Africa | Jackson School of Geosciences | The University of Texas at Austin
An international team of geophysicists has uncovered compelling evidence that tectonic activity approximately 20 million years ago created a land bridge between Eurasia and Africa via the Arabian Peninsula. This geological event facilitated the migration of various animal species, including the ancestors of modern elephants, giraffes, and hominins, from Eurasia into Africa, which had been relatively isolated since the breakup of the supercontinent Gondwana.
The formation of this land bridge resulted from the collision between the Arabian and Eurasian tectonic plates. This collision led to the uplift of the Arabian Peninsula and the closure of the Tethys Seaway, effectively splitting it into what are now the Mediterranean and Arabian Seas. The closure of the Tethys Seaway had significant climatic and ecological consequences, including alterations in ocean circulation patterns and the aridification of regions such as the Sahara Desert.
The newly formed land connection enabled a significant faunal exchange between Eurasia and Africa, known as the Proboscidean Datum Event. This event is marked by the migration of proboscideans (elephant ancestors) and other species into Africa, as well as the dispersal of African species into Eurasia . This biogeographical interchange had profound implications for the evolutionary trajectories of numerous species, including primates.

Refutiing Creationism - How Environmental Variability in Africa Produced Co-operative, Intelligent Humans
This article is best read on a laptop, desktop, or tablet
Environmental Variability Promotes the Evolution of Cooperation Among Humans: A Simulation-Based Analysis | Research News - University of Tsukuba
In a compelling example of how environmental change can drive evolutionary development, two researchers, Masaaki Inaba and Eizo Akiyama, of the University of Tsukuba, Japan, have used computer simulations grounded in evolutionary game theory to demonstrate how intensified environmental variability in Africa during the Middle Stone Age may have promoted the evolution of cooperative behaviour and enhanced cognitive abilities in archaic hominins.
Fundamental to this research is the scientific consensus that Darwinian evolution is the only credible framework for explaining the patterns observed in the fossil record and the genomic evidence for natural selection.
The study also directly challenges a common creationist misrepresentation: that Richard Dawkins’ metaphor of the “selfish gene” implies that evolution inherently favours selfishness and therefore cannot account for altruism or cooperation. This flawed interpretation ignores the fact that evolutionary processes often favour cooperative strategies—especially in complex, fluctuating environments—without invoking supernatural causes.
Severe environmental change can fragment populations into small, isolated groups, where genetic drift plays a significant role in evolution. In such settings, beneficial mutations can rapidly drift to fixation, potentially giving the group a competitive advantage over neighbouring populations when contact is re-established. This process can produce a pattern in the fossil record that resembles 'punctuated equilibrium', with the apparent 'sudden' appearance of a major innovation.
