The problem with having a god who exists merely to fill gaps in human knowledge and understanding — as the god of creationism does — is that science has been steadily shrinking those gaps ever since the scientific method emerged and the Church lost its power to persecute scientists for discovering inconvenient truths. Today, only a few small gaps remain, scattered throughout the body of scientific knowledge —particularly in biology, which holds special interest for creationists.

Creationism persists because there are still people with such a poor understanding of science that they believe the authors of ancient religious texts — written during the Bronze Age, when humanity's knowledge gaps encompassed nearly everything in their small world — had access to some deeper, divine insight. Although what they wrote is often naively simplistic and demonstrably wrong in almost every respect, creationists insist that it somehow surpasses anything modern science has produced in terms of accuracy and reliability.

One of the few remaining gaps where creationists attempt to place their god — the abiogenesis gap — has just shrunk further. Predictably, this will be ignored, dismissed, or misrepresented by creationist frauds who exploit carefully maintained ignorance to preserve their cult followings and income streams.

This discovery by chemists at University College London and the Medical Research Council Laboratory of Molecular Biology reveals how a simple RNA molecule can self-replicate under conditions thought to have existed on prebiotic Earth. Many scientists believe this marks the origin of RNA-based life, which eventually gave rise to the more complex protein- and DNA-based life we see today. A self-replicating RNA molecule, competing for limited resources, will naturally evolve to become more efficient — leaving more copies of itself than rival variants. This is classic Darwinian evolution, operating in a context Darwin himself could scarcely have imagined, knowing nothing of RNA or DNA.

The new research is published open access in Nature Chemistry.

Abiogenesis News - Closing Creationism's Favourite God-Shaped Gap - Still No God(s) Found

How membranes may have brought about the chemistry of life on Earth | Department of Biology

Another hefty spadeful of science has just been shovelled into one of creationism’s favourite god-shaped gaps: the ever-shrinking mystery of abiogenesis. This is the gap that, through the intellectually dishonest tactic of the false dichotomy, creationists claim as evidence for their chosen deity.

Not only is this approach scientifically bankrupt, it also conveniently spares them the bother of providing any evidence or a testable mechanism of their own. For a target audience conditioned to see science as an attempt to disprove their god, the logic goes: if science is wrong—or even just incomplete—then “God did it!” wins by default.

But that dreaded moment for creationists, when science finally closes the gap and, like every other gap in history, finds no need for gods or magic in the explanation, draws ever nearer. The latest discovery bringing us closer comes in the form of new research into the origin and function of membranes—an essential step on the path from chemistry to life.

This particular piece of gap-filling comes from a paper published in PLOS Biology, authored by a team led by Professor Thomas Richards, Professor of Evolutionary Genomics in the Department of Biology at the University of Oxford. The researchers demonstrate that early cell membranes could not only have formed through natural processes, but also had the crucial ability to control what passed through them.

In doing so, they explain what had been something of a mystery and a favourite claim of ID creationists - the chirality of 'living' molecules where all amino acids have the same chirality. Creationists claim this shows the hand of an intelligent designer. This work shows it has a natural explanation.

Refuting Creationism - Homing In On Consciousness - No Gods Involved

Landmark experiment sheds new light on the origins of consciousness - Allen Institute

Consciousness, like the Big Bang and abiogenesis, represents a gap in scientific understanding that creationists eagerly exploit as a place to insert their evidence-free deity — the classic “God of the gaps” fallacy. This false dichotomy is the lifeblood of creationism, which appeals to the scientifically illiterate and culturally chauvinistic creationists who view science as a rival to their preferred local religion. According to this view, if science cannot yet explain something, or if it has ever been wrong, then “God did it” wins by default.

However, a major new study suggests that science is closing in on a natural explanation for consciousness. The findings support the idea that consciousness is an emergent property of neurophysiology, leaving no room — or need — for supernatural explanations. In a landmark 2019 collaborative experiment involving human subjects, researchers from the Allen Institute tested two competing theories of consciousness against one another. They published their findings today in Nature, claiming the study marks a pivotal moment in the quest to understand this elusive phenomenon. Further details are available in an Allen Institute news article.

Does planetary evolution favor human-like life? Study ups odds we’re not alone | Penn State University

An interdisciplinary team of astrophysicists and geoscientists has questioned the evolution of a human-like intelligent species. But the question is not about whether, as creationists have been predicting for 50 plus years, but just how easy or difficult was it? That we evolved was never in any doubt.

The relevance of the easy/difficult question is that it affects our calculation of the probability of similar intelligent life evolving on other planets. If each step in its evolution was hard (the 'hard step' model), then we may be alone in the Universe; if easy, then the Universe could be teeming with life.

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.

Study uncovers first evidence of resistance to standard malaria treatment in African children with severe malaria

In another twist of the arms race with human medical science Plasmodium falciparum, the malevolently designed parasite that causes malaria and kills hundreds of thousands of children a year, mostly in Africa, has developed resistance to Artemisinin. Scientists were already aware that resistance had arisen in cases of uncomplicated malaria, but this is the first such incidence of resistance in the more severe form of the disease.

Indiana University School of Medicine researchers, in collaboration with colleagues at Makerere University in Uganda have discovered a case of complicated malaria in a child in Uganda.

Mallevolent Design - How Salmonella Sneaks Past Our Defences To Make Us Sick

Salmonella infects the small intestine and alters the colon environment

Intestinal lumen

New study shows how salmonella tricks gut defenses to cause infection

There is a simple paradox at the heart of creationism that I have never even seen an attempt to resolve. It all comes from two beliefs: there is only one designer god capable of designing living organisms and that designer god designed us complete with our immune system with which we can attempt to resist attack by pathogens, and that pathogens are not the work of this design, but are the result of 'genetic entropy' and 'devolution' since Adam & Eve let 'sin' into the world. The fact that Michael J. Behe, who invented that excuse, has let slip that ID Creationism is Bible literalism in a lab coat seems to be lost on his followers who still dutifully insist that it is a scientific alternative to evolution and should be taught in school science class (presumably now with the tale of Adam & Eve taught as real history and 'sin' as a real force in science).

The paradox is, did the designer god give Adam & Eve an immune system, or did it design an upgrade when 'sin' allowed pathogens to exist? If the former, it was anticipating and planning for the so-called 'fall'; if the latter, it lacked foresight so is not omniscient.

But however creationists resolve this paradox they still have to explain why the 'intelligently designed' immune system doesn't work very well and why whatever is designing pathogens seems to be able to overcome it.

The nonsense about 'sin', 'the fall', etc., is trivially easy to refute because any improvement in a parasite's ability to parasitise its host can't possibly be regarded as a devolution from some assumed initial perfection because an improvement can't be worse that what it's an improvement on. The whole nonsense of 'devolution' is biological gobbledygook, intelligently designed to appeal to scientifically illiterate simpletons who want to fit the Bible superstition somewhere in the reasoning without bothering too much about the logic or the biology.

So, the paradox boils down to why an intelligent designer would be having an arms race with itself so the parasites it creates can continue to parasitise the victims it creates complete with their immune system it created to stop them. Creationists normally flee in terror at the mere mention of arms races, which is why you'll never see them discussed in the cult literature apart from where pathogens are waved aside as 'caused by sin', blah, blah, blah...
So, it would be refreshing indeed to see a genuine attempt by an intelligent design creationist try to give some rational explanation, and hopefully without giving away the fact that ID creationism is merely Christian fundamentalism in disguise, for the discovery by a new UC Davis Health study that shows how the Salmonella bacteria, a major cause of food poisoning, can invade the gut even when protective bacteria are present.

As an added embarrassment for creationists, Salmonella is closely related to Escherichia coli (E.coli) that they usually cite Michael J. Behe as 'proving' it must have been designed by their god because its flagellum is 'irreducibly complex'.

First a little AI background information about Salmonella, where it came from and what it does to us:

Tiny worm makes for big evolutionary discovery | UCR News | UC Riverside

The refutation of creationism continues today with news of another one of those 'non-existent' transitional species that turn up with monotonous regularity only to be dismissed by creationists as 'not transitional but fully formed' with now two gaps in the record where there was originally one, or by simply dismissing the dating method as unreliable and coincidentally wrong by an order of magnitude sufficient to make 6-10,000 years look like x-million years.
Another big disappointment for creationists is the fact that this one is from before the Cambrian when their traditional disinformation claims lots of species popped into existence without ancestors by magic in a single event called the 'Cambrian explosion'. The Cambrian 'explosion' was of course a period of some 6-10 million years during which many of the basic body plans of multicellular organisms evolved.

This fossil however was before then and was clearly the ancestral stem species from which a whole range of Cambrian organism, collectively known as Ecdysozoa evolved. These are a group of organisms with an outer cuticle which is shed periodically as the organism grows. The vast group includes nematode worms and arthropods such as insects, spiders, crustaceans like crabs, shrimps, lobsters, and the horseshow crab. So, this discovery, which the palaeontologists have named Uncus dzaugisi sits at the base of this branch of the evolutionary tree. It resembled a nematode worm.

Tell me all about the Ecdysozoa, please. Ecdysozoa is a major clade of animals within the larger group known as Protostomia, distinguished by their unique mode of growth, which involves periodic moulting of an external cuticle. The term "ecdysozoa" comes from the Greek word ecdysis, meaning "to strip off" or "to shed," referring to this moulting process.

Characteristics of Ecdysozoa

1. Moulting (Ecdysis):
   • The defining feature of Ecdysozoans is the shedding of their cuticle—a tough, non-living outer layer made of proteins, polysaccharides (like chitin), or collagen. This process allows them to grow, as the rigid cuticle limits continuous size increase.
   • After moulting, a new, larger cuticle is secreted, which hardens over time.
2. Body Structure:
   • Many have a hydrostatic skeleton, relying on fluid pressure in their body cavity for movement and structure.
   • Most lack cilia or flagella in their adult form, distinguishing them from other protostomes.
3. Diversity:
   • The group includes some of the most diverse and abundant organisms on Earth, ranging from microscopic species to large, visible ones.
4. Nervous System:
   • Typically, they have a ventral nerve cord and a dorsal brain, with varied sensory adaptations.

---

Major Groups Within Ecdysozoa
Ecdysozoa includes eight phyla, with two of the most well-known being Arthropoda and Nematoda:

1. Arthropoda
   • The largest and most diverse group of animals, including insects, arachnids, crustaceans, and myriapods.
   • They have segmented bodies, jointed appendages, and a hard exoskeleton.
   • Examples: Butterflies, crabs, spiders, centipedes.
2. Nematoda (Roundworms)
   • Microscopic to macroscopic worms with a cylindrical, unsegmented body.
   • Found in nearly every habitat on Earth, often as parasites in plants and animals.
   • Examples: Caenorhabditis elegans (a model organism), Ascaris (a human intestinal parasite).
3. Tardigrada (Water Bears)
   • Microscopic, water-dwelling animals known for their extreme resilience to harsh environments.
   • They can survive desiccation, radiation, and even the vacuum of space.
4. Onychophora (Velvet Worms)
   • Segmented, soft-bodied terrestrial animals with slime glands used for capturing prey.
5. Priapulida
   • Marine worms with a tubular body, often found burrowing in sediment.
6. Kinorhyncha
   • Tiny, segmented marine animals often referred to as "mud dragons."
7. Loricifera
   • Microscopic animals inhabiting marine sediment, with a complex, retractable body.
8. Nematomorpha (Horsehair Worms)
   • Parasites as larvae, often controlling the behaviour of their insect hosts.

---

Evolution and Phylogeny

• Ecdysozoa was proposed as a clade in 1997, based on molecular evidence (notably studies of ribosomal RNA).
• They share a common ancestor with other protostomes but diverged early to adopt their unique moulting strategy.
• Their evolutionary success is evident in their sheer numbers and adaptability, especially in arthropods.

---

Ecological and Economic Importance

1. Ecological Roles:
   • Many ecdysozoans are key components of ecosystems as decomposers, predators, prey, and parasites.
   • Insects, a subgroup of arthropods, are critical for pollination and nutrient cycling.
2. Economic Impact:
   • Beneficial: Insects (e.g., bees) aid in agriculture, while nematodes play a role in soil health.
   • Harmful: Some ecdysozoans are pests or parasites causing diseases in humans, animals, and crops.

---

Fun Facts

• Tardigrades can enter a state called cryptobiosis, surviving for decades without water or food.
• Arthropods are the most successful phylum, with over a million described species, and likely many more undiscovered.
• Nematodes may account for about 80% of individual animals on Earth.

The discovery was made by a team from University of California, Riverside (UCR), led by Professor Mary Droser a distinguished professor of geology. The have explained their findings in the journal, Current Biology, and in a UCR press release:

Tiny worm makes for big evolutionary discovery

---

UC Riverside scientists have described ‘Uncus,’ the oldest ecdysozoan and the first from the Precambrian period

---

Everyone has a past. That includes the millions of species of insects, arachnids, and nematode worms that make up a major animal group called the Ecdysozoa. Until recently, details about this group’s most distant past have been elusive. But a UC Riverside-led team has now identified the oldest known ecdysozoan in the fossil record and the only one from the Precambrian period. Their discovery of Uncus dzaugisi, a worm-like creature rarely over a few centimeters in length, is described in a paper published today in Current Biology.

Scientists have hypothesized for decades that this group must be older than the Cambrian, but until now its origins have remained enigmatic. This discovery reconciles a major gap between predictions based on molecular data and the lack of described ecdysozoans prior to the rich Cambrian fossils record and adds to our understanding of the evolution of animal life.

Mary L. Droser, co-author Earth and Planetary Sciences University of California, Riverside
Riverside, CA , USA.

The ecdysozoans are the largest and most species-rich animal group on Earth, encompassing more than half of all animals. Characterized by their cuticle — a tough external skeleton that is periodically shed — the group comprises three subgroups: nematodes, which are microscopic worms; arthropods, which include insects, spiders, and crustaceans; and scalidophora, an eclectic group of small, scaly marine creatures.

Like many modern-day animal groups, ecdysozoans were prevalent in the Cambrian fossil record and we can see evidence of all three subgroups right at the beginning of this period, about 540 million years ago. We know they didn’t just appear out of nowhere, and so the ancestors of all ecdysozoans must have been present during the preceding Ediacaran period.

Ian V. Hughes, first author
Organismic and Evolutionary Biology
Harvard University, Cambridge, MA, USA.

DNA-based analyses, used to predict the age of animal groups by comparing them with their closest living relatives, have corroborated this hypothesis. Yet ecdysozoan fossil animals have remained hidden among scores of animal fossils paleontologists have discovered from the Ediacaran Period.

Ediacaran animals, which lived 635-538 million years ago, were ocean dwellers; their remains preserved as cast-like impressions on the seabed that later hardened to rock. Hughes said uncovering them is a labor-intensive, delicate process that involves peeling back rock layers, flipping them over, dusting them off, and piecing them back together to get “a really nice snapshot of the sea floor.”

This excavation process has only been done at Nilpena Ediacara National Park in South Australia, a site Droser and her team have been working at for 25 years that is known for its beautifully preserved Ediacaran fossils.

Nilpena is perhaps the best fossil site for understanding early animal evolution in the world because the fossils occur during a period of heightened diversity and we are able to excavate extensive layers of rock that preserve these snapshots. The layer where we found Uncus is particularly exciting because the sediment grains are so small that we really see all the details of the fossils preserved there.

While the team didn’t set out to find an early ecdysozoan during their 2018 excavation, they were drawn to a mysterious worm-like impression that they dubbed “fishhook.”

Sometimes we make dramatic discoveries and sometimes we excavate an entire bed and say ‘hmmm, I’ve been looking at that thing, what do you think?’ That’s what happened here. We had all sort of noticed this fishhook squiggle on the rock. It was pretty prominent because it was really, really deep.

Because it was deep, we knew it wasn’t smooshed easily so it must have had a pretty rigid body. At this point we knew this was a new fossil animal and it belong to the Ecdysozoa.

Ian V. Hughes

After seeing more of the worm-like squiggles the team paid closer attention, taking note of fishhook’s characteristics. Other defining characteristics include its distinct curvature and the fact that it could move around — seen by trace fossils in the surrounding area. Paul De Ley, an associate professor of nematology at UCR, confirmed its fit as an early nematode and ruled out other worm types.

The team called the new animal Uncus, which means “hook” in Latin, noting in the paper its similarities to modern-day nematodes. Hughes said the team was excited to find evidence of what scientists had long predicted; that ecdysozoans existed in the Ediacaran Period.

It’s also really important for our understanding of what these early animal groups would have looked like and their lifestyle, especially as the ecdysozoans would really come to dominate the marine ecosystem in the Cambrian.

Ian V. Hughes

The paper is titled “An Ediacaran bilateran with an ecdysozoan affinity from South Australia.” Funding for the research came from NASA.

Highlights

• A new, motile bilaterian is described from the Ediacaran of South Australia
• Features including morphology and movement suggest an ecdysozoan affinity
• This discovery firmly places ecdysozoans in the Precambrian

Summary
Molecular clocks and Cambrian-derived metazoans strongly suggest a Neoproterozoic origin of many animal clades.^1,2,3,4 However, fossil bilaterians are rare in the Ediacaran, and no definitive ecdysozoan body fossils are known from the Precambrian. Notably, the base of the Cambrian is characterized by an abundance of trace fossils attributed to priapulid worms,^5,6 suggesting that major divisions among ecdysozoan groups occurred prior to this time. This is supported by ichnofossils from the latest Ediacaran or early Cambrian left by a plausible nematoid,^7,8,9 although definitively attributing this inferred behavior to crown-Nematoida remains contentious in the absence of body fossils.¹⁰ Given the high probability of the evolution of Ecdysozoa in the Proterozoic, the otherwise prolific fossil record of the Ecdysozoa, and the identification of more than 100 distinct Ediacaran genera, it is striking that no Ediacaran body fossils have been confidently assigned to this group. Here, we describe Uncus dzaugisi gen. et. sp. nov. from the Ediacara Member (South Australia), a smooth, vermiform organism with distinct curvature and anterior-posterior differentiation. The depth of relief of Uncus is unique among Ediacara fossils and consistent with a rigid outer cuticle. Ecological relationships and associated trace fossils demonstrate that Uncus was motile. Body morphology and the inferred style of movement are consistent with Nematoida, providing strong evidence for at least an ecdysozoan affinity. This validates the Precambrian origin of Ecdysozoa, reconciling a major gap between predicted patterns of animal evolution and the fossil record.⁴

I think my favourite quote from one of the scientists is "We know they didn’t just appear out of nowhere, and so the ancestors of all ecdysozoans must have been present during the preceding Ediacaran period", which just about describes the difference between someone who knows the Theory of Evolution is correct because he understands the evidence for it, and a creationists who believes in fully formed living organisms made from nothing, magically popping into existence from nowhere, with magic spells cast by an unproven supernatural deity their mummy and daddy told them about.

The ancestral form, the transitional species, was in exactly for rock formation of exactly the right age which the theory of evolutionary decent with modifiction from a common ancester predicted.

And in case a creationist is tempted to try the 'radiometric dating is flawed/wrong/faked fallacy. The Ediacaran rock formation these fossils were found in was independently dated several different ways that all converged on a 98-million-year span from 635 to 538 million years ago known as the Ediacaran. The Most important being the Uranium-Lead (U-Pb) dating of zircons found in the layers of volcanic ash sandwiched within the rocks. To compress 600 million years of radioactive decay into less than 6-10,000 years would have caused Earth's rocks to melt and the seas to boil away. And the weak nuclear force would have been so weak that atoms could not have formed, let alone life, and there would have been no planet and no universe to fine tune for it either.

Common Ancestry - Ancient Choanoflagellates Genes Used To Make A Mouse

Scientists recreate mouse from gene older than animal life - Queen Mary University of London

If there is one thing designed to get creationists chanting 'Common Designer!' it's evidence of the same gene doing the same thing in lots of different organisms, no matter how distantly related they are.

But when that gene is needed because of a basic design blunder long ago in the evolution of multicellular organisms, that chant looks increasingly forlorn.

For example, scientists have just shown how SOX and POU genes isolated from a single-celled choanoflagellate can be used to convert a mouse cell to function as the stem cell to clone another mouse. The reason this works is because something needs to reset the epigenetic setting in specialised cells. In a multicellular organism like a mouse, this effectively means any cell produced after the first few cell divisions of the fertilised zygote.

But why would a single-celled organism like a choanoflagellate need to do that? The answer it that epigenetics originally evolved to make an organism more able to respond to environmental changes and stresses.

The two accumulation phases of the Mediterranean salt layer during the Messinian Salinity Crisis.
In the first phase, salt accumulated in a Mediterranean Basin filled with brine; in the second phase, salt accumulated in a Mediterranean completely isolated from the Atlantic Ocean, as a result of the significant drop in sea level in the western and eastern Mediterranean sub-basins.

© Giovanni Aloisi

Despite living not a stone's throw from it, the authors of Genesis appear to have known next to nothing about the Mediterranean, and, having guessed that Earth was created about 4,000 earlier they blundered on with their preposterous, counterfactual mythology. Had they been away of real history they might have made a better fist of it, but there was no way they could have known that about 5.5 million years earlier there was no sea to speak of; instead there was a salt-filled depression due to what is now called, The Messinian Salinity Crisis.

This event was caused by land rising up under the straights of Gibraltar restricting inflow from the Atlantic and eventually closing it altogether, and, as water levels fell, the ridge between Sicily and the North African coast formed another barrier, effectively dividing the Mediterranean into two seas.

New Book - The Failure Of Creationism: The Theory That New Was

The Failure of the Wedge Strategy

AI generated image (ChatGPT4o)

While writing my previous book, Refuting Creationism: Why Creationism Fails In Both Its Science and Its Theology I realised what a monumental failure the creationist movement, in particular the Discovery Institute's 'Wedge Strategy', had been.

Just about every paper published in the fields of biology, palaeontology, cosmology and archaeology refuted just about every claim on which creationism rests, whether the claims of a young earth with the YEC obsession with a global flood, the supposed absence of 'transitional fossils', the proclaimed 'impossibility of 'life' or genetic information arising without a magic creator', or Michael J Behe's 'irreducible complexity'.

None of them have garnered the slightest degree of support on the scientific community and it holds as true today as it did When Behe was forced to admit under oath in the Kitzmiller case, "...there are no peer reviewed articles by anyone advocating for intelligent design supported by pertinent experiments or calculations which provide detailed rigorous accounts of how intelligent design of any biological system occurred."

Despite the regular repeated claims by creationists that the Theory of Evolution is a theory in crisis, about to be overthrown in scientific circles by Intelligent design theory, there is not the slightest indication of that happening. False witnessing remains the single most important tactic of the creationist movement as it seeks to fool ignorant people of the scientific validity of the childish superstition. Scientific support for Darwinian evolution remains as strong today as it was in 1991 when the Discovery Institute launched its campaign to confuse and misinform public and scientific opinion about the strength of the evidence for the TOE and the claimed 'gaps' and 'defects' in the theory.

The so-called 'controversy' was never anything of the sort and attempt to 'teach the controversy' and introduce Christian fundamentalism into public school science classes disguised as a legitimate science have been met with barrage of condemnations and detailed rebuttals from major science professional bodies and teaching estabishments.

The only success the Discovery Institute can claim, is in its campaign to confuse American public opinion about the level of support for creationism in biomedical science circles. While some 98-99% of biomedical scientists fully accept the TOE as the only explanation for humans in their modern form, American public opinion believes only some 66% do and that there is a debate to be had.

This new book, The Failure of Creationism: The Theory That Never Was, is an exposé of that failure with examples of recent scientific papers that implicitly refute creationism and appendices containing the absurd claims by creationists of the TOE imminent demise, the published opposition to teaching creationism in science classes by major scientific and educational bodies and the Discovery Institute's politically subversive 'Wedge Strategy'.

Refuting Creationism - How The Grand Canyon Reveals Life On Earth 540 Million Years Before 'Creation Week',

The Grand Canyon's Horseshoe Bend, where creationisst believe a raging torrent of flood water did a 180 degree turn and headed back the way it came.

USU Geologist, Colleagues Rewrite Textbooks With New Insights From Bottom of the Grand Canyon

The Grand Canyon often features in creationist disinformation websites because it needs to be explained away in terms of a history of Earth lasting only some 6-10,000 years and because it is easy to fool people who want to be fooled that it is somehow evidence if a global flood, and in particular how the water in the alleged flood ran away. Cult frauds also pretend the different rock layers in the canyon wall can all be explained in terms of sediment deposited during their god's supposed genocidal flood.

The truth, as usual with creationist claims, is nothing like the childish myth they like to pretend is real history. In fact, the walls of the Grand Canyon are a record of plate tectonics and climate change over hundreds of millions of years and mesh completely with what is known of Earth's history from other sources.

An indication of how creationists cult leaders are terrified of the information in the walls of the Grand Canyon, can be gauged from the notorious creationist purveyor of disinformation, Andrew Snelling's article on the creationists disinformation site, Answers in Genesis and the lengths he went to to obtain sample without disclosing exactly where he got them from, as related in this article in science. Snelling argued that it discriminated against his religion to require him to provide GPS coordinates of his samples! Clearly, Snelling believes his religion requires his 'science' to lack precision and reproducibility in case someone else tried to replicate his measurements and finds his to be bogus.

Snelling was subsequently given permission to collect samples under supervision and then wrote up his findings to try to explain away the fact that his findings didn't conform to his YEC preconceptions. His excuses include the creationists go-to excuse - the unsubstantiated claim that the uniformly old age of the rock he obtained must be because radioactive decay rates used to be different by several orders of magnitude!
One of Snellings stated objectives was to prove that the deformed Tapeats sandstone deposits, which he assures his readers are not fractured, despite the fact that photographs show fractures, were soft when deformed. He mentions this early in his article but then quietly drops the subject, presumably because his findings contradict his claim.

His findings are soundly refuted here.

Clearly, it is important to creationist cult leaders that their dupes are badly misinformed about the date of the rocks in the walls of the Grand Canyon, and it is obvious why, as this paper by geologists from Utah State University, together with colleagues from the University of New Mexico, Boise State University, Idaho, the University of Las Vegas, Nevada and the Denver Museum of Nature & Science, Denver, Colorado, shows. The rocks at the bottom of the canyon are from the Cambrian, 540 million years before creationists dogma says Earth was made from nothing by magic.

Other rocks map exactly onto what is known of changes in sea level and climate due to plate tectonics and how the canyon itself was carved into those strata is fully explainable in terms of erosion by a river flowing over a river bed that was rising slowly due to forces beneath Earth's crust over a period of millions of years.

Perhaps the most embarrassing thing for creationists is the thing they normally avoid like the plague - the famous Horseshoe bend, which requires their credulous dupes to believe a raging torrent of water, for no apparent reason, changed direction by over 180 degrees and headed back the way it came, when raging torrents of water are notoriously uni-directional.

And why on Earth anyone would imagine the water from a global flood would flow through a canyon in the middle of North America into the Pacific Ocean is anyone's guess and not something Andrew Snelling or any other creationist apologist has ever attempted to explain, simply leaving it to their parochial and culturally chauvinistic dupes to assume that anything important that happened in world history must have happened in the USA.

SARS-CoV-2 “steals” our proteins to protect itself from the immune system

Although COVD-19 has been mostly brought under control by medical science and the vaccination campaign, it still kills thousands of people a year, but nowhere near the volume of deaths during the initial wave when world-wide health services came close to collapse and economies were on the point of ruin.

But there is still much to learn about why it was so virulent and successful.

To an admirer of creationism’s divine malevolence it must have seemed like a triumph of design, as it filled hospitals, killed millions and wrecked economies, helped by its supporters in the evangelical Christian churches who opposed measures to mitigate the worse effect of the virus, and then opposed the vaccination campaign with lies, scare tactics and the most infantile conspiracy theories imaginable, to help ensure the virus got to as many people as possible.

Now, a team of researcher from the Medical University of Vienna together with colleagues from the Medical University of Innsbruck have discovered how the virus protects itself from the immune system creationists believe their putative intelligent designer designed to protect us from the virus’s and other pathogens it designs to make us sick, would grace the pages of another 'intelligent design' polemic by Michael J. Behe and his Deception Institute. It depends on several components of a system being present in a classic 'irreducibly complex' system that creationists wave around as 'proof' that the locally-popular creator god is real because they can't understand how it could have evolved.

New insights into the Denisovans – the new hominin group that interbred with modern day humans - News & Events | Trinity College Dublin

In marked contrast to the childish creationist notion of a single founder couple being magically created without ancestors 6-10,000 years ago, evidence is growing that one ancestral species that contributes some of its DNA to modern non-African humans, the Denisovans, were once widespread especially in Southeast Asia and may have reached South America, or at least people carrying some Denisovan DNA may have done, but not via the traditional route - Siberia, Beringia and Alaska - followed by later Homo sapiens.

My understanding is that they and Neanderthals were most likely direct descendants of H. erectus that migrated out of Africa some 2 million years ago and gave rise to the Denisovans in Eastern Eurasia and Neanderthals in Western Eurasia. These two then interbreed with the H. sapiens migrants as they came up out of Africa and spread throughout Eurasia and down to Melanesia, Austronesia and Oceania.

So, rather than a single ancestral couple magically created out of dirt, without ancestors, as creationists believe, modern non-African humans don't have an ancestral couple, they don't even have a single ancestral species but are the result of hybridization between at least three ancestral species.

There is also evidence, according to two researchers from Trinity College, Dublin, Ireland, that there may have been several regional populations of Denisovans, each of which contributed to the Homo sapiens genome at different times. As with other hominin species, they were diversifying as they spread in what may have been the beginnings of classical allopatric speciation.

The Denisovan DNA that was retained by H. sapiens as they migrated into the different environments in Asia was that which gave them an advantage, such as the ability to survive in the low oxygen partial pressure of the Tibetan Plateau - something that the Tibetans have inherited - immunity to certain endemic pathogens and an improved ability to keep their body temperature up during cold weather by burning stored body fats - something that Innuits have inherited.

Refuting Creationism - How Bird's and Bat's Wings Evolved

Unlike birds, the evolution of bats’ wings and legs is tightly coupled, which may have prevented them from filling as many ecological niches as birds.

Bats’ and birds’ evolutionary paths are vastly different | Cornell Chronicle

Unlike an intelligent designer, the process of evolution can't go back to basic and start again. It is normally an additive process that has no control over what it has to work with and simply refines and improves on what is there. That's not to say new structures can't evolve but they do so by enlarging or remodelling something that was already there - the membrane of a bat's wing, for example is the webbing that exists in the tetrapod embryo between the fingers and toes, while the feathers of a bird's wing are highly modified scales. Both those structures evolved out of tissues that were already there. It would have been impossible for a bat to grow wing feathers instead of a membrane, for example, because the earliest mammals had lost their scales and evolved fur.

But of course, that would not have been a problem for an omnipotent intelligent designer who, having designed one wing would not need to set about designing another way to do the same thing.

So, constrained as evolution was by what it could use, it's not really surprising that birds and bats evolved on two different trajectories, with the only thing in common being flight (and of course the basic vertebrate skeletal body plan).

Unintelligent Design - How Evolution Rescued an Unintelligent Heath-Robinson Design Blunder

The thing about evolution that distinguishes it from intelligent design is that evolution is utilitarian. It settles for something that works better than what preceded it, which is different from designing a perfect solution to a problem. Near enough is good enough because anything which is an improvement gets pushed up the frequency listing in the gene pool. So, organisms over time have accumulated sub-optimal systems that sometimes fail and cause other problems.

One of those systems is the way DNA is replicated - which is so error prone that error correction mechanisms have evolved over time, but they don't always work either, so we have the phenomenon of the 'jumping genes' that get inserted in the wrong place in the genome, sometime in the middle of a functional gene or in a control section adjacent to a functional gene, causing genetic defects.

So, in the best Heath-Robinson approach to design, rather than abandoning that design and starting again, the way any intelligent designer would do, another layer of complexity is needed to try to mitigate the occasion when the system fails.

So, what organisms have evolved over the years is a process for neutralising these 'jumping genes' by attaching methyl groups to one of the bases which prevents it being transcribed. This is a part of the epigenetic system by which the specialised cells of multicellular organisms turn of unwanted genes and only allow the genes for their speciality to be active - a layer of complexity needed because the way cells replicate was inherited from their single-celled ancestors where the whole genome needs to be included in every daughter cell.

Animals, such as mammals have two enzymes which attach this methyl group depending on the DNA 'context', but plants have multiple enzymes for doing the same thing. The question is why do plants need these multiple enzymes?

The egg or the chicken? An ancient unicellular says egg! - Medias - UNIGE

Scientists believe they may have cracked the chicken and egg 'problem' that creationists have been fooled into thinking is a killer problem for the Theory of Evolution. With their child-like understanding of evolution, creationists can't imagine how species emerge over time from earlier species by a process of evolution and think that their mythical magic creation without ancestors is actually what happens, or at least what evolutionary biologists think happens. So, they imagine explaining how the first chicken hatched from the first egg before there was a chicken to lay it, is an insurmountable problem.

In fact, of course there never was a first chicken just as there never was a first human, and eggs are simply a phase in the life cycle of, in this case, chickens, so hens' eggs are chickens just as much so as adult hens are. The ancestral species that the Southeast Asian jungle fowl evolved from had been laying eggs ever since they diverged from the egg-laying avian dinosaurs that had evolved from the egg-laying theropod dinosaurs, etc, etc, back to the egg-laying tunicates and chordates in the Cambrian and their egg-laying ancestors...
