Refuting Creationism - A Mass Extinction 252 Million Years Before 'Creation Week' - And Why Some Survived It

March: Amphibians bounce-back from Earth’s greatest mass extinction | News and features | University of Bristol

The thing about mass extinctions, apart from the fact that they occurred so long before creationists dogma says there was even a universe, is that they refute any notions of a planet fine-tuned for life, or any notions of a perfect creator creating all life as it is today. In fact, it was the growing interest in palaeontology and the growing realisation that the fossil record contained so many extinct species, which caused people to start to question the notion of divine creation by a perfect god.

It was also the existence of so many intermediate fossils and series showing progressive change over time that fostered the idea of evolutionary change, although, until Darwin and Wallace thought of evolution by natural selection, how it worked was a matter of speculation.

The end-Permian mass extinction was one of the most significant events in the history of life on Earth - a history, 99.9975% of which occurred before creationists think their little god created the small flat planet with a dome over it in the Middle East, that creationists like to imagine was the entire universe.

However, fortunately for subsequent life on the planet, and without whom it is unlikely that humans would exist, a handful of species survived, most notably some amphibians.

New Book - The Evolution of Creationism: How Creationism Has Adapted To Survive


Creationism should have faded into obsolescence long ago, having been thoroughly disproven by the overwhelming scientific evidence for evolution, in stark contrast to the total absence of evidence for a creator or any plausible explanation of how an unproven entity could create anything. Its continued persistence is primarily due to the efforts of a small group of vocal advocates who, in their pursuit of preserving their stake in the creationist movement, have abandoned any semblance of intellectual or personal integrity. These individuals have launched a concerted campaign of deliberate misrepresentation of science, while intentionally fostering profound ignorance among their audience to protect their interests.

The irony is that the creationist organisations such as the Deception Institute are having to adapt their tactics and make subtle changes to how they sell creationism in view of the (mostly) hostile changes in the legislative, educational and scientific environment in which they compete with science in the market place of ideas in exact mimicry of the natural evolutionary process they try to deny and misrepresent.

My latest book, written with the assistance of the AI client, ChatGPT4, the eighth in the series on Intelligent Design, describes how creationism has been adapted to try to compete with science in the struggle for the resource of public and scientific opinion on which it depends.

I use AI to research the subject and provide detailed descriptions of events and how the creationist movement has responded. AI can, in minutes, research and fact-check, then synthesise its findings into a few well-written paragraphs, something that would take weeks to do manually.

From the book's introduction:

Creationism has never been a static ideology. While the core belief in a divine creator remains unchanged, the arguments and strategies used to oppose evolution have continuously adapted. From early biblical literalism to modern Intelligent Design, the Anti-evolution movement has undergone significant transformations in response to scientific discoveries, legal challenges, and cultural shifts.

Unintelligent Design - Flightless Birds Still Have Feathers for Flight


When birds lose the ability to fly, their bodies change faster than their feathers - Field Museum

As though designing birds with wings that they can't fly with wasn't stupid enough, it seems creationism's idiot designer designed them with flight feathers too. That is, if you believe the childish nonsense of special creation of species without ancestors, which is a central superstition of the creationist cult. And presumably, because it's also central to the cult that species don't evolve, it must be assumed that every extinct species was created without ancestors too, so they can't have evolved from ancestors either.

Which makes it all the more puzzling that a study has shown that as flightless birds became flightless over time, they tended to retain feathers that were characteristic of flying birds, and in particular, those of their flying relatives.

In other words, as flightlessness evolved, the last thing to change were their feathers.

Which begs thew question why creationism’s putative designer gave flightless birds feathers that looked as though they had been inherited from flying ancestors.

Of course, there is a rational explanation for this, and it doesn't involve magic creation by a blundering idiot behaving like a mindless process operating without a plan.

Refuting Creationism - How The Ice Giants Created Complex Life In The Oceans


Glacial grooves stemming from the Wisconsin glaciation at Kelleys Island, Ohio

Giant ice bulldozers: how ancient glaciers helped life evolve - News at Curtin | Curtin University, Perth, Australia

It's generally recognised that complex, multicellular life began in the oceans from colonies of single-celled organisms, but what isn't known is what environmental triggers promoted the evolution of this complexity.

Now researchers from Curtin University, Perth, Australia, in collaboration with the University of Portsmouth and St. Francis Xavier University, Canada, believe they have shown a correlation between this event, or series of events and the melting of vast ice sheets which covered Earth in a period known as snowball Earth. The trigger was not so much the melt-water and rise in sea levels as the minerals this melt-water brought with it. This sudden abundance of minerals was the result of the slow grinding of Earth's surface by giant glaciers as they gouged their way across the planet.

The inner ear of Neanderthals reveals clues about their enigmatic origin

Creationists will confidently tell you that a loss of genetic information is invariably fatal so can play no part in evolution. They believe this because the frauds at the Discovery Institute have misled them into believing that every piece if DNA and therefore every piece of genetic information has a purpose.

And yet researchers have shown that it was a loss of genetic information following a population bottleneck that gave rise to the classic Neanderthals as a distinct species from their pre-Neanderthal ancestors.

This was the conclusion from a study led by Alessandro Urciuoli (Institut Català de Paleontologia Miquel Crusafont, Universitat Autònoma de Barcelona) and Mercedes Conde-Valverde (Cátedra de Otoacústica Evolutiva de HM Hospitales y la Universidad de Alcalá), researchers measured the morphological diversity in the structure of the inner ear responsible for our sense of balance: the semicircular canals.

Malevolent Designer News - How Cancer is Cleverly Designed to Trick Our Immune System


Mitochondrial transfer and metabolic reprogramming of the tumor microenvironment aid cancer immune evasion.
How Cancer Cells Trick the Immune System by Altering Mitochondria - Okayama University

There is an ongoing arms race between medical science and cancer - and guess whose side creationism's intelligent designer appears to be on.

Yep, it's the same intelligent designer who designed cancers in the first place by creating an error-prone DNA replication mechanism that goes wrong, as does the error-correction mechanism it designed to try to rectify its faulty design with an added layer of complexity. And one of the results of it going wrong is cancer.

One of the more hopeful treatments for cancer was a tailor-made immunotherapy in which specific antibodies to the cancer cells were used to attack the cancer and treat it like a parasitic pathogen, by training the immune system to recognise the cancer and attack and destroy it.

But, true to form, creationism's divine malevolence has hit back by designing a response by cancer cells to attack by cells of the immune system.

We can be sure this is the work of creationism's intelligent designer because William A Dembski, the Discovery Institute's flunky and pseudoscientist in residence, tells us that any genetic sequence that produces a function must have been given 'specified information' in the form of the DNA that codes for that specific protein because, so he claims, specified information is too complex to have evolved.

Abiogenesis News - Closing Another of Creationism's God-Shaped Gaps - Still No God Found


How life’s building blocks took shape on early Earth: the limits of membraneless polyester protocell formation – ELSI|EARTH-LIFE SCIENCE INSTITUTE

Creationism’ ever-shrinking little god that sits in the abiogenesis gap, just got smaller with the news that researchers led by PhD student Mahendran Sithamparam of the Space Science Center (ANGKASA), Institute of Climate Change, National University of Malaysia, working at the Earth-Life Science Institute (ELSI) in the Institute of Science, Tokyo, Japan, have shown how primitive protocells could have formed under a wide range of realistic probiotic Earth conditions. The research team included scientists from Taiwan and China.

The research showed that membraneless protocells could have formed by polymerization of alpha-hydroxy acids (αHAs) to form polyester microdroplets, not to be confused with the modern plastic polyester. These polymers were polymers of esters - simple organic compounds which are chemically similar to the monomers that make modern polyester fibres.

Unintelligent Design - How Creationism's Heath-Robinson Designer Muddles Through But Still Messes Up.


Quality control during splicing: When an error in the precursor mRNA is detected, the spliceosome is blocked, the recruited control factors interrupt the “normal” cycle, and a molecular short circuit causes the spliceosome to disassemble.

Spliceosome: How Cells Avoid Errors When Manufacturing mRNA

Q. How can you tell when something is designed by a supreme intelligence with the inerrant ability of foresight?

A. It works perfectly, without errors and does exactly what it was intended to do, nothing more and nothing less.

Q. How can you tell when something is 'designed' by a natural, utilitarian process like evolution by natural selection?

A. It works most of the time, even if not very efficiently, is over-complex and so prone to errors and doesn't anticipate change. It also frequently requires additional layers of complexity to compensate for its errors and inefficiency.

Sadly for intelligent design advocates, structures and processes found in nature are almost never perfect and free from errors and, when examined closely, are seen to be error-prone, suboptimal and requiring additional complexity to compensate for the errors and inefficiencies. And these error-correction mechanisms are themselves error-prone and prone to failure.

One such mechanism, the details of which have just been worked out by researchers at the Heidelberg University Biochemistry Center (BZH) in collaboration with colleagues from the Australian National University, is the system of spliceosomes found in eukaryote cells, that correct the errors in messenger RNA (mRNA) before they are transcribed into functional proteins.

The reason these large nuclear proteins are required is because the DNA the mRNA is transcribed from is contains 'introns' - small sequences that are not part of the gene being coded for. Imagine a computer database of words, which, when a retrieved, inserts random letters in the middle of the word.

Unintelligent Design - An Arms Betwen The Sexes!


Male flies' better vision called the females' bluff | University of Gothenburg
When dance flies mate, females make themselves more attractive by swallowing air and laying their hairy legs along their bodies to look like they are full of eggs. New research shows that the males have developed better eyesight, probably to detect the deception.
As I showed in my books, The unintelligent Designer: Refuting the Intelligent Design Hoax and Unintelligently Designed Arms Races: How Nature Refutes Intelligent Design, the natural arms races that are ubiquitous in nature make no sense as the work of an intelligence. It is simply not an intelligent act to have an ultimately pointless arm race with yourself.

Arms races happen because one side doesn't know the other side's next move but falling behind could be ultimately fatal. Both sides have no option but to use the 'Red Queen strategy' of running ever faster just to stand still. It makes as much sense as playing poker with yourself. As the act of an intelligence, it would mean the designer sees the solution to yesterdays' problem as today's problem to be solved. It probably tells us a great more than they might wish us to know that creationists think this is a sign of supreme intelligence.
The latest such arms race to be revealed by science makes even less sense from an intelligent design perspective if that's possible. This one is an arms race between the sexes in an order of insects known as dance flies and is the result of the two different strategies the males and females use to ensure they get the best mate and so produce the fittest offspring.

Dance flies are (mostly) predatory flies that kill and eat other insects. To attracts a female, males perform a dance with other males in a flying display. The females attract a male by showing him her abdomen in full of eggs and she is ready to be inseminated. The male then pursues the female and presents her with a dead insect as food. She then allows him to mate with her. They will then go off and repeat the mating rituals so both will mate with multiple partners. The female then lays her fertilised eggs in damp soil where they hatch and live as larvae and pupa until ready to hatch and repeat the cycle.

It is in the females reproductive interest to attract the fittest males and she does this by flying in front of him to display a large body full of eggs, while the male concentrates his efforts of pursuing the female most likely to produce a large batch of eggs, and presenting her with a nutritious meal in return for mating with her.

Malevolent Design - How Sudan Virus is Cleverly Designed to Kill 50% of Its Victims

New Study Reveals How Sudan Virus Binds to Human Cells | Midwest Antiviral Drug Discovery (AViDD) Center

It's shaping up to be a thrilling month for devotees of creationism's divine malevolence as science finds out just how brilliantly its nasty little parasites are designed to make us sick and increase the suffering in the world, although quite why any normal person would worship a hate-filled sadistic psychopath is even more of a mystery than the mechanism by which it designs and creates organisms.

The latest is the details of how the Sudan virus (a variant of Ebola with a 50% 'success' rate in terms of deaths of its victims) has an improved method of binding to our cells to gain entry and start the killing process. Like Ebola, it binds to receptors on the cell surface, but because it has just 4 different amino acids in its coat proteins, it binds much more efficiently - a factor which probably contributes to its high kill rate.

Malevolent Design - More Brilliance from Creationism's Divine Malevolence

Hijacking of plasmin by dengue virus for infection - NUS Faculty of Science | NUS Faculty of Science

If you're a creationists who follows the latest science (if there is such a thing), you must be bursting with admiration for the ingenuity of your beloved intelligent designer for the way its brilliance at making us sick and spreading more suffering in the world is being revealed by science.

In the last few days, I've reported on how HIV, the virus that causes AIDS, is designed to hijack our cell's metabolic processes to ensure its own survival, and how the zika virus that cause the serious birth defect, microcephaly, in children if their mothers become infected during pregnancy, is brilliantly designed to make our skin produce more of the scent that attracts mosquitoes, so ensuring it is spread as widely as possible.

Now we have a superb example of this skill in malevolent design revealed by researchers from the National University of Singapore (NUS) who have discovered how the dengue virus is designed to make sure as many people as possible are infected by it. And this is breath-taking in its ingenuity. It is spread by the divine malevolence's favourite insect vector - the mosquito.

Refuting Creationism - How Bonobos Help Us Find Something When They Know We Don't Know Where It Is

Don't know something? Apes can tell | Hub

The thing about Creationists is that, whilst they can't make testable predictions and their claims are non-falsifiable, they nevertheless make claims, based not on what the evidence shows, but on what they would like to be true to be as important as they like to imagine they are.

For example, they claim that there are certain features of humans that distinguish us from all the other species (ignoring that all species have unique features, which is what makes them distinct species). Most of these claims will be about our intelligence, social interactions and ethics and our artistic and aesthetic abilities.

Curiously, because they reject the idea that our ability to empathise is the basis of our social ethics, preferring to claim they get their morals from their god because that makes them feel superior to people with a different religion or none, they nevertheless will assert that compassion is one of those uniquely human characteristics that sets us apart from the other animals, so is evidence of our special creation by a magic creator who created everything just for us.

But like so many of their claims, this one turns out to be not only not unique to humans but evidence of common ancestry with the other apes - in this case bonobos, our closest relative. Bonobos have the ability to realise when there is something we don't know and to understand when we need to be educated - something that psychologists beleved was a uniquely human ability.

Unintelligent Design - Sex Determination in Octopuses - For 480 Million Years

Octopuses have some of the oldest known sex chromosomes | OregonNews

Although few of them will know enough to understand why, the genetic basis for sex determination in different organisms is a problem for intelligent design advocates because it illustrates a few embarrassing things which can't be explained as the design of an intelligent designer.

Firstly, there are several ways in which gender is determines, rather than the single method a single intelligent designer of all living things would have settled for (see the AI information panel). Secondly, the actual basis is consistent within major clades such as mammals, birds and orders of insects such as Hymenoptera (Bees, wasps and ants), and thirdly, because the methods are unstable over evolutionary time, since the sex chromosomes are unpaired in the heterozygous gender, so the unpaired chromosome tends to acquire mutations, which are not corrected by cross over during meiosis, and the non-sex-determining genes tend to be conserved on the chromosome which is paired in the homozygous gender.

In mammals, this means that the Y-chromosome tends to degenerate; in some species of rodents, which have a short generation time and large litters, so evolution can progress faster than in most other mammals, the Y-chromosome has disappeared, to be replaced by an alternative sex-determining system. No intelligent designer worthy of the name would design a process that degenerates and need to be replaced every few million years.

Malevolent Design - How Zika Is Designed to Spread Maximum Suffering.

Zika uses human skin as ‘mosquito magnet’ to spread virus further | LSTM

January was something of a joyous month for devotees of creationism's divine malevolence. Following closely behind the news of how it brilliantly designed HIV to use our cells defences against us so making it better at infecting and killing us, we have news of another breathtakingly brilliant design of a nasty little pathogen - the zika virus that causes microcephaly in children if their mothers become infected during pregnancy.

This news is that it turns our skin into a living 'magnet' to attract the vector that spreads it - mosquitos - so ensuring it gets transmitted to as many victims as possible. It does it by altering a gene and protein expression in dermal fibroblasts, causing the skin to produce odours that are attractive to mosquitoes. In effect, calling them to come and feed.

Before creationists start bleating unscientific and biologically non-sensical nonsense about 'genetic entropy' and devolution allowed by 'sin' I should point out that no mutation that conveys a benefit on an organism can be regarded as 'devolutionary'. It is classic evolution by natural selection. And, as per William Dembski's gibberish about 'specified complexity', any complex DNA or RNA sequence that codes for a specific function must be regarded as 'specified complexity', using his argument, so must have been specified by a magic designer, according to his misuse of statistics and probability. Or perhaps a creationist could explain why such a highly specific function of converting a human gene to make special mosquito-attracting scents, is not an example of Dembski's 'specified complexity'.

So, how was this, in creationist terms, intelligently designed virus, discovered to have this touch of brilliance in its design? That was the result if a new study by an international team led by Liverpool School of Tropical Medicine. Their findings are published, open access, in Communications Biology.

Refuting Creationism - Humans Have Been Selectively Breeding Sheep Since 1000 Years Before 'Creation Week'

Ancient DNA history of sheep and humans - News & Events | Trinity College Dublin

Domesticated animals are an embarrassment for creationists who believe that their god created all the animals for the convenience of mankind, because just about every domesticated animal (or plant for that matter) has been highly modified by selective breeding to make it suitable for whatever purpose it was domesticated for.

An intelligent god could have made them fit for purpose in the first place, if it had really created them for mankind's convenience. This shows that either the creation myth is wrong, or the creator god lacked the foresight to know what humans would be using the animals for. So, we've had to modify them, in some cases. almost beyond recognition as the descendants of their wild ancestors, to make them fit for purpose.

And it gets worse when we discover that the domestication process began long before the same creation myth says all the animals were created in the same week as humans.

Sheep, for example, according to a study by an international and interdisciplinary team of researchers led by geneticists from Trinity College Dublin, and zooarchaeologists from Ludwig Maximilian University Munich and the Bavarian State Collections of Natural History (SNSB) were first domesticated over 11,000 years ago. An analysis of their genome also reflects patterns of migration in the human population, with whom sheep have been intertwined for over 11,000 years.

Unintelligent Design - Vestigial 'Fossil' Ear Muscles Still Try to Function


Muscles of the ear

‘A neural fossil’: human ears try to move when listening, scientists say | Biology | The Guardian

In my book, The Body Of Evidence: How the Human Body Refutes Intelligent Design I list very many examples of the sort of design only a fool would produce - examples of sub-optimal compromises in structures and processes that could have been less error-prone and more efficient in terms of resource use or function.

These also included vestigial structures and system that still exist, sometime causing problems such as appendicitis when the functionless appendix becomes infected, and the wasted metabolism in making all the tiny hairs on your body stand up in cold weather using the tiny arrector pili muscles and the autonomic nerves that supply them.

Now we have another example, involving the superior and posterior auricular muscles that once moved the ears in a remote simian ancestor, but now only serve as party tricks for the few of us that can wiggle our ears.

Refuting Creationism - How Horseshoe Crabs Have Evolved And Diversified


Indo-Pacific Horseshoe Crab, Tachypleus tridentatus

Preserving Asian horseshoe crab populations through targeted conservation strategies

In creationist mythology, horseshoe crabs have remained unchanged for 400 million years, so they prove there is no such thing as evolution and Earth is only 6-0,000 years old. Apart from the typical lack of joined-up thinking in that non sequitur, there are a couple of fallacy at work here.

Firstly, evolution does not necessarily involve major changes in the phenotype because it happens at the genetic level, so the genome is where we need to look to find evidence of it (or lack of it); secondly there is no requirement for a species that is already adapted to its environment to change unless its environment changes in a way that requires adaptation. This might include increased predation, depletion of food resource, major changes in temperature or oxygenation, increased competition from another species, etc.

With their child-like understanding of evolution, creationists assume a species must change into something else for evolution to happen.

In fact, as a team a research team led by Associate Professor Frank Rheindt from the Department of Biological Sciences at the National University of Singapore (NUS) Faculty of Science have now shown, there are four different species of horseshoe crab which have all diversified from a common ancestor.

Refuting Creationism - How The Common Barn Swallow Shows Evolution In Progress

A front-row seat to evolution: What common barn swallows can teach us about how new species form | CU Boulder Today | University of Colorado Boulder

This paper in Science passed me by last December but it's too good to ignore because it is an example of something that creationists insist has never been seen because it doesn't happen - evolution in progress. And, to annoy creationists even more, it's an example of something Charles Darwin proposed as a mechanism for speciation - mate selection - as the isolating mechanism.

Barn swallows are one of the species that has formed a commensal relationship with humans that does not, like many other commensal species, involve it in consuming our crops either in the fields or in storage, from when we began building permanent or semi-permanent buildings. They are now dependent on our barns and out-houses as nesting places.

Unitelligent Design - How The Giant Clam Has a Needlessly Complex Way To Get Nutrients


How tiny algae shaped the evolution of giant clams | CU Boulder Today | University of Colorado Boulder

You can depend on creationism's idiot designer to never do something the obvious uncomplicated way when there is an obscure and much more complicated way to achieve the same result. It's almost exactly like it's a mindless fool, blundering about without a plan who sometimes happens across something that works and sticks with it, trying to make the best of it with more blundering.

Quite the opposite of what anyone other than a creationist would call intelligent, in fact.

For example, having designed a giant clam to live in nutrient poor coral reefs, it then designed them to have algae living symbiotically inside them, supplementing their megre diet got by filtering the seawater, with sugars manufactured by photosynthesis. This enables the giant clam to grow up to 4.5 feet (1.4 metres) in length and weigh over 700 pound (317 Kg).

Any intelligent designer could have either designed them to live in a less nutrient-poor environment or given them the chloroplasts the algae have to achieve the same result far more simply.

But of course, the giant clam wasn't intelligently designed; it evolved by the utilitarian evolutionary process that is constrained by its evolutionary history and so finds suboptimal but functional processes that a needlessly complex. This complexity impresses creationists because, not understanding how evolution works, they imagine it reflects intelligent design, instead of refuting it.

Refuting Creationism - Beetles Were Feeding on Dinosaur Feathers - 100 million Years Before 'Creation Week'


Fossils reveal a 100-million-year-old relationship between feathered dinosaurs and feather-feeding beetles | University of Oxford

To normal people, the discovery of feather-eating beetles and feather fragments in 105-million-year-old amber, 30 million years before there were birds might be a clue that something had feathers before bird had them, suggesting that birds might have evolved from whatever that was.

Not so, creationists, however. Creationists conclude that any evidence that doesn't agree with them must be wrong because their evidence-free dogma is sacred and therefore uninfluenced by real-world evidence.

So, the following is just something else for creationists to ignore while they pretend to know better than the experts who have, unlike creationists, actually studied the subject.

It is news that a study, co-led between the Geological and Mining Institute of Spain of the Spanish National Research Council (CN IGME-CSIC) and Oxford University Museum of Natural History (OUMNH) has shown that beetles fed on the feathers of dinosaurs about 105 million years ago. This is based on an analysis of spectacular fossil amber fragments, from the locality of San Just in north-eastern Spain, revealed moults of tiny beetle larvae tightly surrounded by portions of downy feathers.

The feathers belonged to an unknown theropod dinosaur that lived around 105 million years ago, during the Early Cretaceous. This means that the feathers could not have come from a ‘modern bird’ species, since current evidence indicates that this group appeared about 30 million years later in the fossil record, during the Late Cretaceous.
