Malevolent Designer News - How To Keep Ahead In The COVID Game Against Creationism's Divine Malevolence - Keep Being Boosted


How long does immunity last after a COVID infection?

Creationists stuck with the evidence of parasites and viruses that appear to be designed for two purposes only - making more copies of themselves and increasing the suffering in the world by making us sick and die - traditionally try to ride two horses. They blame something else, like 'The Fall' or 'Sin' for them, whilst still arguing that their putative designer god is supreme in all things and the only entity capable of creating complex organisms.

They also get in a terrible muddle when asked whether their 'designer' god included an immune system to protect us from these parasites when it designed us before 'The Fall', in which case it was planning for it all along, or whether there was a subsequent upgrade to V.1.2, in which case it couldn't have been omniscient and had to redo its design to account for the unforeseen.

But whatever rationalisation creationists can think up for these mutually contradictory beliefs, we are left with the fact that viruses like the SARS-CoV-2 virus and our immune system are locked in an arms race, in which human medical science has had to get involved because the immune system isn't fit for purpose, and the protection it gives us is only temporary.

Meanwhile, medical scientists, aware of the fact that evolution by natural selection is going to continually produce new variants of the virus and that these viruses may become better at evading our defences, continue to apply that knowledge and develop new vaccines against the latest variants.

The following article by Lara Herrero, Research Leader in Virology and Infectious Disease, and Wesley Freppel, Research Fellow, Institute for Glycomics, both of Griffith University, Australia explains why regular vaccination with boosters to keep out immune system primed for the latest iteration of the arms race with a latest version of the virus.

Malevolent Designer News - How Bacterial Pathogens Are Cleverly Designed to Invade Their Victim's Body


Functional model for Yen-Tc toxicity. Following ingestion of the Tc, it is likely that the surface-bound chitinases bind to and/or degrade the chitin-rich peritrophic membrane of the insect midgut. Cell surface recognition is likely facilitated by motifs within the A subunits prior to internalization. Similarities to the well characterized bacterial binary toxin systems (e.g., anthrax, cholera, diphtheria) suggest a mechanism involving receptor-mediated endocytosis followed by pore formation and translocation of the B and/or C components into the cytosol (I), although alternative mechanisms (e.g., II, III) cannot be ruled out.

Imagine you're in charge of an invading army laying siege to your enemy's outer defences. How do you neutralise them?

One way would be to send a small group of soldiers, packed with high explosives and deadly toxins on a kamikaze mission into the defences, with instructions to detonate their explosives and so spread the toxins when inside to destroy the defences and kill the defenders. You could improve on that by removing any temptation the suicide bombers might have to not detonate their defences by automating the trigger to fire as soon as they encountered the defender.

That's exactly what a team at the Max Planck Institute for Molecular Physiology (MPI MOPH), Dortmund, Germany, have found bacteria use to gain access to their victim’s body and make their hosts sick and die. The team, led by Stefan Raunser, Director of MPI MOPH, have published their findings, open access, in Nature Microbiology. Their work is described in a MPI MOPH press release:

Creationism in Crisis - Flying Reptiles In The Mendip Hills - 200 Million Years Before 'Creation Week'

200 million years, give or take a few thousand years, before creationists believe Earth and life on it were all created by magic from nothing in a week, gliding lizard-like reptiles related to ancestral crocodiles, were gliding from tree to tree, and probably hunting flying insects, in what is now the Mendip Hills, near Bristol, UK. The area around Bristol was then an archipelago of islands in a sub-tropical, shallow sea.

Fossil remains of these reptiles were found by University of Bristol Masters student Mike Cawthorne, researching numerous reptile fossils from limestone quarries, in what was then the biggest sub-tropical island at the time, called the Mendip Palaeo-island.

As the Bristol University press release explains:
The study, published today in Proceedings of the Geologists’ Association, also records the presence of reptiles with complex teeth, the trilophosaur Variodens and the aquatic Pachystropheus that probably lived similarly to a modern-day otter likely eating shrimps and small fish.

The animals either fell or their bones were washed into caves and cracks in the limestone.

“All the beasts were small,” said Mike. “I had hoped to find some dinosaur bones, or even their isolated teeth, but in fact I found everything else but dinosaurs.

“The collections I studied had been made in the 1940s and 1950s when the quarries were still active, and palaeontologists were able to visit and see fresh rock faces and speak to the quarrymen.”

Professor Mike Benton, from Bristol’s School of Earth Sciences, explained: “It took a lot of work identifying the fossil bones, most of which were separate and not in a skeleton.

“However, we have a lot of comparative material, and Mike Cawthorne was able to compare the isolated jaws and other bones with more complete specimens from the other sites around Bristol.

“He has shown that the Mendip Palaeo-island, which extended from Frome in the east to Weston-super-Mare in the west, nearly 30 km long, was home to diverse small reptiles feeding on the plants and insects.

“He didn’t find any dinosaur bones, but it’s likely that they were there because we have found dinosaur bones in other locations of the same geological age around Bristol.”

The area around Bristol 200 million years ago in the Late Triassic was an archipelago of small islands set in a warm sub-tropical sea.

Bristol’s Dr David Whiteside added: “The bones were collected by some great fossil finders in the 1940s and 1950s including Tom Fry, an amateur collector working for Bristol University and who generally cycled to the quarries and returned laden with heavy bags of rocks.

“The other collectors were the gifted researchers Walter Kühne, a German who was imprisoned in Great Britain in the 2nd world war, and Pamela L. Robinson from University College London. They gave their specimens to the Natural History Museum in London and the Geological collections of the University of Bristol.”
Abstract

During the Late Triassic and Early Jurassic, the area around Bristol and South Wales was an archipelago of islands occupied by diverse small-sized tetrapods. The largest of these palaeo-islands was Mendip Island, now forming the Mendip Hills, and the location of some famous fossiliferous sites. These sites have not been described in detail before, and we present new data on three of them. Highcroft has yielded only sparse remains of rhynchocephalians, and Batscombe famously the gliding reptile Kuehneosuchus latissimus. Emborough yielded the richest fauna of the three, abundant pseudosuchians including crocodylomorphs as well as the gliding reptile Kuehneosaurus latus, rare trilophosaurs, a probable thalattosaur, rhynchocephalians, and the mammal Kuehneotherium. These include some of the last known taxa of clades that died out in the end-Triassic mass extinction. We report a new taxon of sphenosuchid crocodylomorph similar to Saltoposuchus and a find of Pachystropheus, an aquatic reptile shared with Holwell and the bedded Rhaetian at Blue Anchor Point, Aust and Westbury Garden Cliff. The discovery of a fish vertebra strengthens the model of Emborough fissure filling in a marginal marine location. The Emborough fauna differs from coeval assemblages from Cromhall, Tytherington and Ruthin in the scarcity of sphenodontians and the absence or great rarity of procolophonids as well as the abundance of kuehneosaurids and crocodylomorphs.

1. Introduction

The Triassic (252–201 Ma) was a crucial time in the recovery, restructuring and diversification of vertebrate life (Benton and Wu, 2022). Many modern groups including lissamphibians, turtles, lizards, crocodiles, and mammals originated or diversified in the Late Triassic, part of the process of the recovery of life from the end-Permian mass extinction, but stimulated by the Carnian Pluvial Episode 233–232 Ma, following which climates became more arid, and the new groups, including dinosaurs, had opportunities to diversify (Brusatte et al., 2010; Chen and Benton, 2012; Benton et al., 2014; Bernardi et al., 2018; Dal Corso et al., 2020; Benton 2021; Benton and Wu, 2022).

The end-Triassic mass extinction (ETME), 201 Ma, was probably caused by sharp warming from greenhouse gases erupted by the Central Atlantic Magmatic Province (CAMP), associated with the beginning of rifting and opening of the North Atlantic (Blackburn et al., 2013). The environmental crisis led to widespread extinctions of many tetrapod clades including procolophonids, placodonts, kuehneosaurids, thalattosaurs, allokotosaurians and phytosaurs. Many pseudosuchians such as the rauisuchids also became extinct but the Crocodylomorpha survived leading to the modern living crocodilians. Whether the ETME was a single crisis at the end of the Triassic or began minimally 100 ka before the earliest known eruptions (Davies et al., 2017) is debated. Indeed, there is good evidence for several earlier events, one at the Norian–Rhaetian boundary (Rigo et al., 2020.1) and one equivalent to the middle of the Cotham Member in the British Rhaetian succession (Wignall and Atkinson, 2020.2), both marked by carbon isotope excursions and evidence for substantial loss of marine species. The spacing of these events is entirely dependent on estimates of the duration of the Rhaetian, with its beginning variously dated at 205.7 Ma and 201.7 Ma, making the stage either 4.2 or 0.2 Myr in duration (Maron et al., 2015; Ruhl et al., 2020.3).

These considerations around the importance of the Triassic as a whole, and the Late Triassic in particular, in documenting the origin of modern ecosystems on land and in the sea, as well as the evidence for phased bursts of extinction through the Rhaetian, place fresh importance on understanding the Late Triassic and Early Jurassic fossil faunas found bordering the Bristol Channel, around Bristol and in South Wales. These faunas are preserved across a sub-tropical archipelago (Fig. 1) in fissure fillings, deposits of soil and other debris accumulated in karstic cave systems (Whiteside et al., 2016; Lovegrove et al., 2021.1). First finds were isolated bones of the sauropodomorph dinosaur Thecodontosaurus in the Worrall Road Quarries in Bristol (Riley and Stutchbury, 1836, Riley and Stutchbury, 1840; Ballell et al., 2020.4) and then mammal remains at Holwell Quarry (Moore, 1859), and later recognition by Charles Moore that these were Mesozoic-aged fissures eroded into Carboniferous limestone. The study of the fissures began again in the late 1930s and the 1940s with the work of Walter Kühne and his discoveries of mammal remains at Holwell and elsewhere (Kühne, 1949; Savage, 1993; Whiteside and Duffin, 2017.1; Benton et al., 2024).

(For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
Map from Lovegrove et al. (2021.1).
The fissure faunas have been reviewed several times (Robinson, 1957a; Fraser, 1994; Whiteside et al., 2016), and one of the key land masses was the Mendip Palaeoisland (Lovegrove et al., 2021.1), the site of five fossiliferous fissure sites, namely Emborough, Batscombe, Highcroft, Holwell, and Windsor Hill (Fig. 1). These sites have been reported before (Robinson, 1957a; Fraser, 1994) although not extensively, but Emborough has been featured in several publications (Robinson, 1957a, Robinson, 1957.1b, Robinson, 1962) because of the remarkable specimens of kuehneosaurids, also abundantly represented at Batscombe. These unique finds, however, are not replicated at other fossiliferous fissure sites on the Mendip Island, even at Highcroft and Holwell (Fig. 1). Likewise, although Emborough has produced abundant remains of archosauromorphs, these are very rare at Holwell.

Our aim is to document three of the five Mendip Island fissure localities, Emborough, Batscombe, and Highcroft, whose terrestrial assemblages have not been published in detail before, and to present data on geology and taphonomy as well, to allow comparison with the other Late Triassic fissure faunas around Bristol and in South Wales.

But then what did the authors of Genesis know about the climate in, and location of, what is now south-east England 200 million years earlier, when they didn't even know about Europe and thought Earth was small, flat and just a few thousand years old? This is why so much of it is now having to be reclassified as 'allegorical' or 'metaphorical' by mainstream Christians, leaving only a dwindling cult of fruitloop fanatics still believe it is the inerrant word of an omniscient creator god, laughable though that demonstrably absurd, childish notion is.

Ten Reasons To Lose Faith: And Why You Are Better Off Without It

This book explains why faith is a fallacy and serves no useful purpose other than providing an excuse for pretending to know things that are unknown. It also explains how losing faith liberates former sufferers from fear, delusion and the control of others, freeing them to see the world in a different light, to recognise the injustices that religions cause and to accept people for who they are, not which group they happened to be born in. A society based on atheist, Humanist principles would be a less divided, more inclusive, more peaceful society and one more appreciative of the one opportunity that life gives us to enjoy and wonder at the world we live in.

Creationism in Crisis - Hagfish Genome Shows How Genetic Information Arises Without Magic


Hagfish, until now the only vertebrate that hadn't had its genome sequenced.
Image credit: Juan Pascual Anaya
January: Hagfish | News and features | University of Bristol

One of the mysteries of vertebrate evolution is from where did all the genetic information come, but a recently completed sequencing of the hagfish genome has solved that mystery.

Creationists traditionally parrot the claim that information can't increase without magic because of some half-baked notion that it is like energy, so is subject to the third law of thermodynamics, which states that energy can neither be created nor destroyed.

But it only takes a moment's thought to realise that every time a cell replicates, the amount of genetic information normally doubles, without the help of magic, because it is simply a controlled organisation of existing matter. Similarly, if the genome gets doubled, or lengths of DNA get accidentally duplicated, this is simply the incorporation of existing matter into the resulting genome. No new matter is created yet the amount of information in the genome increases.

The other source of creationist confusion stems from them not understanding the difference between information and meaning. Meaning is information in the context of the environment. I'll illustrate this with a simple analogy:

How Science Works - Correcting A Mistake About Megalodons - But Still Biting A Chunk Out Of Creationism


The Megalodon may have neem slimmer but longer than this illustration shows.
Catmando/Shutterstock
The Megalodon was less mega than previously believed | News

A scientific principle that creationists seem to find baffling, is based on the intellectually honest position that opinion must be guided by evidence. It is that scientific opinion is always provisional and subject to change if the evidence changes, so evidence is frequently re-examined and reassesses, and scientific opinion is adjusted accordingly. This is why science textbooks are revised periodically and new editions produced, incorporating the newer thinking,

A simple analogy is that of driving to an airport to catch an important flight. You might check the expected driving time by checking in an old route planner from the 1950's, which might tell you the journey, in the days before traffic congestion, would take about 90 minutes, then you might check a few days before the flight, using an online route planner and learn that the journey will take about 2 hours at that time of day.

Do you just regard the 1950's version as an indisputable fact and plan your journey accordingly? How about the one a few days ago? No! A sensible person, regards both those as provisional pending more up-to-date information, and checks again on the day, when they might discover that there is a road closure and a diversion in place, or there is a serious incident on the motorway, reducing the traffic to a slow crawl for 20 miles, so the journey will now take 3 hours. Was the first estimate wrong? Which is the best estimate to go with now? The old ones based on information available at that time, which might have caused you to miss your flight, or the new one based on updated information?

On that analogy, creationists are in the position of using information not from the 1950s, but from the Bronze Age, some of it from a time before even the wheel was invented, let alone air-transport, motor cars or motorways!

In 2022, based on very scant information (a tooth and some vertebrae), a team of researchers estimated the size of an extinct shark, the megalodon (big tooth) shark, Otodus megalodon, to be at least 50 feet long, and possibly as much as 65 feet. This was based in the assumption that O. megalodon was like a scaled up great white shark, Carcharodon carcharias, so its dimensions could be estimated by comparing what they had with those of C. carcharias.

Now a team or researchers co-led by biologist, Phillip Sternes of the University of California Riverside (UCR), and DePaul University paleobiology, Professor Kenshu Shimada, have reassessed the evidence and concludes that O. megalodon was slimmer than the great white but probably considerably longer than the earlier estimate. This greater length would probably have meant a more efficient digestive system having longer to digest food and extract nutrients from it, so its hunting and predation would have had less impact on the ecosystem than first thought. It would still have been an apex predator but maybe not as voracious as first thought.

Their research is published in the journal Palaeontologia Electronica, an explained in a UCR news release:

Malevolent Design - How The Divine Sadist Makes One in Three Infected Babies' Future Lives Difficult Even If They Recover From Bacterial Meningitis

Bacterial meningitis damages one in three children for life | Karolinska Institutet Nyheter

Left untreated, bacterial meningitis is usually fatal, but even if it is treated with antibiotics and the patient recovers, creationism's divine sadist who designed the bacteria, ensures one in three of them will be lefts with varying degrees of disability, including mental impairment, blindness, deafness or loss of motor control that will be with them for life.

This is the conclusion of a new study published two days ago in JAMA Network Open. It was conducted by a team under the leadership of Federico Iovino, associate professor in Medical Microbiology at the Department of Neuroscience, Karolinska Institutet.

The team compiled data on 3,500 people who contracted bacterial meningitis as children between 1987 and 2021 and compared them to just over 32,000 matched controls from the general population. The average follow-up time was 23 years.

As the news release from the Karolinska Institutet explains:

Creationism in Crisis - How Mammalian Brains All Work The Same Way - Just Like They Evolved From A Common Ancestor

Study reveals a universal pattern of brain wave frequencies | MIT News | Massachusetts Institute of Technology.

It's a central dogma of creationism that humans are a special form of life created distinct from all other animals. This is one of the appeals of creationism to those who have such a high opinion of themselves that they like to believe they were created by and have a special relationship with the creator of the entire Universe, which it created specifically with them in mind.

However, when we look for evidence of this biological difference, we find instead evidence that we have the same biology as all other mammals and have much more in common than the relatively small differences that, like all other species, place us in a separate taxon. The similarities for a nested hierarchy which shows how closely (or distantly) related we are to the other mammals, particularly, in descending order, the other African great apes, the other anthropoid apes, the old-world monkeys and the other primates.

But creationists particularly like to point to our greater intelligence and aesthetic appreciation of art and music, and our ability to communicate. However, they too can be shown to be fat from unique to humans, who differ in those respects only by degree. Having special abilities with an organ of our body no more makes us a special creation than an elephant's special abilities with its trunk makes elephants a special creation, or a dolphin's special abilities with sonar makes dolphins a special creation.

Now, a team of neuroscientists from Massachusetts Institute of Technology (MIT), Cambridge, MA, USA and Vanderbilt University, Nashville, TN, USA have shown that there are six distinct layers of the mammalian brain cortex and that each of these is associated with the same distinctive pattern of electrical activity. Their results were the subject of an open access paper in Nature Neuroscience a few days ago.

Creationism in Crisis - When Creationists Believe The Universe Was Being Made From Nothing, People Were Chewing Gum and Eating Trout, Deer And Nuts In Scandinavia

How could the Bible's authors possibly have known what people were doing in Scandinavia when they didn’t even know where Scandinavia was because they thought Earth was a small flat place with a dome over it to keep the water above the sky out, centred on the Middle East?

The answer is that they couldn't of course. Had they done so, they would have concocted much less parochial tales about the things they didn't understand and would have known that Earth was much older than the few thousand years they imagined.

But now we know much better than they did. For example, modern science is able to take the resin people were chewing on (probably to make glue from it) and analyse the DNA in it to see what they had been eating and what organisms they had living in their mouths. It turns out that just about the time when the Bible's authors were setting their creation tale, people in Scandinavia were eating trout, deer and hazelnuts, and suffering from pathogenic bacteria, oblivious of the creation allegedly going on far away in the Canaanite Hills.

Although creationists now tell us that pathogens and other parasites didn't exist before the supposed 'Fall' and must have been made since by a thing called 'Sin', there is no biblical support for this modern invention which has been hurriedly cobbled together to defend the alleged creator god from the charge of malevolence in the design of pathogens which do nothing other than make more copies of themselves and add to the suffering in the world.

Embarrassingly for those creationist apologists, the same study presents compelling evidence of commensal and pathogenic organisms in the mouths of these Scandinavians, just as there are today in modern humans, including bacteria that cause teeth to fall out.

How scientists discovered this is the subject of an open access paper in Scientific Reports and a news release from Stockholm University:

Creationism in Crisis - Biologist Watch Dawinian Evolution Happen - No Magic Was Involved


How does one species become many? | Newsroom - McGill University

Classical (Darwinian) evolution theory explains diversification of one species into several by hypothesising that an advantageous trait in any given environment will convey a fitness advantage in that environment, so carriers of that trait will have more descendants than non-carriers. As the environment varies so the advantageous traits with vary.

Although the logic of that is indisputable, formal proof of it in terms of observing it leading to diversification is hard to come by for several reasons, not the least of which is that speciation can only really be identified retrospectively when a large enough population exists to be able to say this is a new species, and not just a variant. There was no way to predict that a given individual or small population would actually become a new species so no reason to watch what happened. I explained this some time ago in a blog post about monkey diversification, subsequently confirmed by observation.

So, to the consternation of creationists, an international group of biologists led by McGill University have set about providing the evidence to validate the hypothesis, and, to make matters worse for creationists, they did it using the Galápagos finch, also known as Darwin's finch, that gave Charles Darwin the idea of evolution by natural selection as the explanation for biodiversity. So, this work not only validates basic Darwinian theory but also validates Darwin's choice of an example of it.

The biologists’ findings, based on 17 years of observations, are published open access in Evolution and are explained in a McGill University press release:

Creationism in Crisis - An Early Mammal Was Preying On Dinosaurs 125 Million Years Before Earth Existed (According To Creationists)


Fossil: Mammal attacks dinosaur - Canadian Museum of Nature
The fossil sowing the entangled skeletons of the dinosaur (Psittacosaurus) and the mammal (Repenomamus). Scale bar equals 10 cm.
125 years before Earth was magicked out of nothing, according to creationists, there were early mammals preying on dinosaurs in Canada. The problem creationist have is that they get all their information from tales made up by primitive people who knew nothing of Canada, dinosaurs or early mammals and though Earth was created by magic just a few years earlier.

This is how we can tell that their favourite source book is worthless as an account of real science, biology, geography and history. It is quite simply demonstrably and unarguably so wrong about just about everything, as we now know, that it's laughable that grown adults believe any of it.

Q: How do we know that early mammals were preying on dinosaurs 125 million years ago?

A: Because we have the evidence.

It comes in the form of a fossil of an early mammal attacking a dinosaur, dated to 125 million years old, as described in a paper published in the journal Scientific Reports. The fossil shows a (smaller) mammal in the process of attacking or maybe even eating alive, a (larger) dinosaur. The pair were suddenly engulfed in a volcanic debris flow.

Creationism in Crisis - The Travels Of An Alaskan Mammoth 4,000 Years Before 'Creation Week'


Mammoths lived in interior and Arctic Alaska up until about 13,000 years ago. By analyzing the tusk of a mammoth, we can learn about where it lived throughout different times of its life.

Woolly mammoth movements tied to earliest Alaska hunting camps | UAF news and information

Readers may remember a blog post from last November which described how scientists had tracked the lifetime movements of a male Alaskan mammoth that lived 17,100 years ago, by analysing the isotope record in its tusks.

This is possible because mammoth tusks, like those of elephants, grow continually throughout their lifetime and contain a record of the stable isotopes of strontium (87Sr and 86Sr) in their food, deposited in annual growth rings similar to those of trees, which is dependent on the ratios of those isotopes in the soil the plants grew in. By comparing the record in their tusks with known isotope maps, their movement can be mapped.

Creationists should note that these are naturally-occurring, stable, i.e., not radioactive, isotopes of strontium, so they do not decay to other elements over time, nor do the ratios change significantly over time, so modern maps of these isotope ratios in the soil are valid for tens of thousands of years ago.

Now the same team who used this technique to work out the travels of a male Alaskan mammoth, 17,100 years ago, have repeated used it to map the travels of a female which lived 3,000 years late, and have shown that humans had established encampments close to the routes these mammoths used. The mammoth tusk used was excavated from the Swan Point archaeological site along with the remains of two juvenile mammoths and signs of a campfire, stone tools and the butchered remains of other animals.

The account of the discovery is published, open access in Science Advances and is explained in a news release from the University of Alaska at Fairbanks:

Creationism in Crisis - How Mammoths Evolved During The 700,000 Years They Lived in Siberia Prior To 'Creation Week'


Woolly mammoths evolved smaller ears and woolier coats over the 700,000 years that they roamed the Siberian steppes | ScienceDaily
What could the authors of Gensis know about the fauna of Alaska when they thought Earth was a small, flat planet centered on the Canaanite hill country? They didn't even know much about the history of their close neighbours in Egypt and Mesopotamia, let alone the remote areas of Asia.

So, they were oblivious of the fact that there were woolly mammoths there and had been for some 700,000 years. This is why there are no mammoths in the Bible, nor their relatives, Asian and African elephants, for that matter. To Bronze Age Canaanite hill farmers these animals, and where they lived and the people who lived alongside them, simply didn't exist. So, they concocted tales which to us are ludicrously unrealistic, such as tales about a magic man magically making stuff from nothing with magic words, about 5,000 years before they were making the tales up, followed by an equally ludicrous tale of a genocidal flood about two thousand years later with two of all known species surviving for a year, sealed in a wooden box with no ventilation. They thought breath was something to do with 'life' and didn't know about oxygen or why the animals would have needed it, so didn't see anything wrong with a tale about hundreds of animals and 8 humans being sealed in a floating wooden box for a year.

But now, thanks to science, we know better and can see what they got wrong, and why they could not have privy to real scientific knowledge, or knowledge about real geography and history.

One of the things they got spectacularly wrong was the childish belief that all the animals around them and the planet they lived on, were all created in a few days and none of the animals had ancestors, because they didn't even know their domestic animals like goats, sheep, cattle, doves and pigs had all been selectively bred from wild ancestors.

And of course, they couldn't even have guessed that there were mammoths in Siberia which had been evolving there for 700,000 years until going extinct about 9,000 years earlier.

But a team of Swedish and Russian scientists, led by David Díez-del-Molino of the Centre for Palaeogenetics and Department of Zoology, Stockholm University, Stockholm, Sweden, has now examined the genomes of 23 woolly mammoths, including that of the oldest known remains from 700,000 years ago, and compared them to 28 genomes of modern Asian and African elephants, to gain an understanding of the evolution of this species of mammoth. Their findings are published in an open access paper in Current Biology and explained in a Cell press release (taken here from the copy in Science Daily):

Creationism in Crisis - Revealing The Mysteries of Earth's Fourth Mass Extinction - 200 Million Years Before 'Creation Week'.

Mysteries of Earth’s ancient mass extinction event revealed

In that multi-billion year history of planet Earth, long before creationism's little god allegedly created a small, flat planet with a dome over it, and put living things on it, the real Earth had already had several mass extinctions when the ecosystem changed so radically and quickly that most species couldn't evolve fast enough to survive.

This give the lie to creationist claims that Earth is finely-tuned for life because, quite frankly, very few of the species that have evolved on it last more than a few million years before being killed off by one catastrophe or another that any omniscient deity worthy of the description could and should have foreseen and planned for.

The fourth of those mass extinctions occurred at the end of the Triassic period when a dramatic rise in greenhouse gasses due to volcanic activity led to rapid global warming and a significant shift in the planet’s biosphere, ending the Triassic period and launching the Jurassic.

The parallel with today when a rise in greenhouse gasses has been caused by industrial pollution and burning fossil fuels is striking.

Now a new insight into this mass extinction has been revealed by researchers from the University of Southern California's Dornsife College of Letters, Arts and Sciences, using a novel "ecospace framework" method that categorizes animals beyond just their species. It accounts for ecological roles and behaviors — from flying or swimming predators to grazing herbivores and from ocean seafloor invertebrates to soil-dwelling animals on land.

As the press release from UCSDornsife explains:

Bigotry News - UK Christians May Retain The Right To Abuse Victims Of Their Choice

Ministers accused of watering down rules around abortion clinic buffer zones | Abortion | The Guardian

Last year, MPs in the House of Commons voted overwhelmingly to back an amendment to the Public Order Act which would have established 'safe zones' around clinics offering pregnancy termination services to women who need them.

This would have made it unlawful for anyone to harass or approach women entering the clinics in an attempt to prevent their access or to influence their choice by publicly shaming them.

Those routinely harassing women in this way are invariably Christians using various underhand tactics and disinformation and even threatening to photograph the women and post their picture on the social media. Women are routinely subjected to abuse and shouts of 'murderer' by sanctimonious bigots exercising what they claim is a God-given right to impose their views on others and deny others basic human rights.

The traditional passive-aggressive threat of 'praying' for the women and the foetus was used routinely with ostentations 'silent' prayer, clearly intended to shame and embarrass women. Only a Christian could weaponise 'prayer' while ignoring what Jesus allegedly told them about casting the first stone and not judging others.

Creationism in Crisis - Scientist Got A Date Wrong - But It's More Bad News For Creationists

Pacific kelp forests are far older than we thought | Berkeley

It used to be thought that the ecosystems along California's coasts, which are centred on kelp forests, evolved about 14 million years ago but the discovery of 32-million-year-old fossil kelp means that estimate needs to be revised to a time before the modern marine mammals, urchins, birds and molluscs which now depend on these ecosystems had evolved.

It also means that kelp was probably an important food for a now-extinct hippopotamus-sized marine mammals, the desmostylians, probable relatives of manatees, sea cows and their terrestrial relatives, elephants.

The 14-million-year-old estimate assumed that all components of an ecosystem co-evolve, but this finding shows that the same foundation can lead to different ecosystems to evolve around them, consistent with new niches providing evolutionary opportunities in which mutation and variance can be selected for. In other words, the meaning of the genetic information is changed by the environment.

The discovery of the fossil kelp holdfasts and its significance is explained in a published paper In Proceeding of the National Academy of Science (PNAS) and in a news release from the University of California at Berkeley (UC Berkeley):

Malevolent Design - No Fun For Creationists As The Candida Family of Fungi Are Evolving To Keep Infecting Us

Candida evolution disclosed: new insights into fungal infections | IRB Barcelona

The Candida genus of fungi are related to yeasts (i.e., single-celled fungi) but are specialists at living in or on our bodies and are common infections in body cavities such as the mouth, anus, vagina and urethra and the genito-urinary and respiratory tract, and other moist areas like armpits, inner surfaces of joints like the elbow and knee, groins and fold beneath breasts and buttocks.

They can also become systemic infections causing organ failure and death, especially in people who are immune compromised for any reason. So, they are a threat to people who are in generally poor health, who have had transplants and need to take immunosuppressive drugs, or people receiving chemotherapy for cancer.

And, like some bacterial pathogens, they are good at evolving immunity to anti-fungal medication.

One species, Candida auris, has evolved multiple drug resistance and is now a serious threat to people in hospital for other conditions.

Now, a research group from the Institute for Research in Biomedicine (IRB Barcelona) and the Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS), led by the ICREA researcher Dr. Toni Gabaldón, has identified hundreds of genes subject to recent, clinically-relevant selection in six species of the fungal pathogen Candida. In other words, the genes that have given Candida species their clinically-relevant drug resistance.

First a little AI background to the Candida genus:

Creationism in Crisis - How Human Skin Colour Evolved in Africa Long Before 'Creation Week'

While creationism's god was creating a small flat Earth with a dome over it to keep the water above the sky out, the people of Africa were evolving and diversifying according to local conditions and gene flow between populations that has resulted in a whole range of skin tones and a genetic variance that is greater in a small population of Africans than in the whole of the extra-African population of the world, reflecting the genetic bottleneck of a small band of migrants moving out of Africa into Eurasia.

Africans had of course had several hundred thousand years to diversify prior to the mythical 'Creation Week' when creationists believe a magic man made of nothing came from nowhere and magicked a universe out of nothing with some magic words, spoken in a language that no-one understood because there was no-one to understand it.

Abiogenesis News - Going! Going! Gone! - How Creationism Favourite Gap Just Got Smaller


ancient hot springs - Press Office - Newcastle University

Hardly any debate about evolution with a creationist will go more than a few exchanges before the creationist gives up trying the traditional fallacies and avoidance tactics and falls back onto ground he or she feels safer on - abiogenesis - with the demand that you explain how the first cell arose fully developed, with the parrot squawk assertion that 'you can't get life from non-life'.

But ask them to define 'life' and they'll break off the debate because it's a term creationists think involves something that science can't explain, but they've no idea what it is or why it should present science with a problem. Ask them to explain how dead food becomes living tissue through the process of digestion and metabolism, if it's impossible, and you probably won't hear from them again.

The gap creationists are trying to shoehorn their favourite creator god into is what they've been programmed to believe is unclosable by science, so it must have been done by the locally popular god. They will of course be unaware of the fallacy of the false dichotomy because it's probably what someone fooled them with, so they just assume it'll work on everyone else.
