Covidiot News - Now Even More Reason to Get COVID Vaccines

This study provides more evidence that Covid vaccination is safe for both current and future pregnancies, and shows in a mouse model that immunization during the earliest stages of pregnancy provides antiviral antibodies to the fetus throughout the rest of pregnancy.

Data contradict fears of COVID-19 vaccine effects on pregnancy and fertility.

Two of the bogus antivaxxer claims with which the politically-motivated covidiot antivaxxer movement is trying to scare women into not getting vaccinated against COVID-19 are:

1. The vaccines cause birth defects if given during pregnancy.
2. The vaccines reduce fertility or cause sterility in women by producing antibodies against the protein syncytin-1, which in humans and related primates is involved in attaching the placenta during pregnancy.

Now both of these antivaxxer claims have been exposed as lies by Alice Lu-Culligan and her colleagues of the Yale School of Medicine, in a paper published open access today in PLOS Biology.

The second piece of disinformation was based on the fact that a small part of the SARS-CoV-2 spike protein that antibodies are produced against by the vaccines has a short sequence of amino acids that is also found in syncytin-1.

This is hardly surprising since syncytin-1 is the remnant of an ancient retrovirus that has been co-opted to aid in the attachment of the placenta in many primates. In fact, it's one of many pieces of evidence of common descent since it is present in all the old-world primates, but not in the new-world primates. The Wikipedia entry for syncytin-1 reads:

Syncytin-1 also known as enverin is a protein found in humans and other primates that is encoded by the ERVW-1 gene (endogenous retrovirus group W envelope member 1). Syncytin-1 is a cell-cell fusion protein whose function is best characterized in placental development.^[3][4] The placenta in turn aids in embryo attachment to the uterus and establishment of a nutrient supply.

The gene encoding this protein is an endogenous retroviral element that is the remnant of an ancient retroviral infection integrated into the primate germ line. In the case of syncytin-1 (which is found in humans, apes, and Old World but not New World monkeys), this integration likely occurred more than 25 million years ago.^[5] Syncytin-1 is one of two known syncytin proteins expressed in catarrhini primates (the other being syncytin-2) and one of many viral genomes incorporated on multiple occasions over evolutionary time in diverse mammalian species.^[6]

ERVW-1 is located within ERVWE1,^[7][8] a full length provirus on chromosome 7 at locus 7q21.2 flanked by long terminal repeats (LTRs) and is preceded by ERVW1 gag (Group AntiGen) and pol (POLymerase) within the provirus, both of which contain nonsense mutations rendering them non-coding.^[9][10] Syncytin-1 is also implicated in a number of neurological pathologies, most notably, multiple sclerosis, as an immunogen.

Increased genetic contribution to wellbeing during the COVID-19 pandemic | PLOS Genetics

Creationist mode:

A new study by Lude Franke and colleagues of the University of Groningen, Netherlands has shown that some individuals were more affected than others by the COVID-19 pandemic, due to their genes.

Of course, any omniscient designer of those genes and of the SARS-CoV-2 virus, such as the one intelligent [sic] design creationists believe is the creator of everything, will have been fully aware of that fact when it created the virus, so can't escape the charge of deliberately targeting certain individuals because of their genetics.

The difference is to be found in how well or badly individuals coped not so much with infection by the virus, but with the overall social effect of the pandemic, including the measures to mitigate and control it.

The new study was published a couple of days ago in the open-access journal PLOS Genetics.

How seascapes of the ancient world shaped genetic structure of European populations - Trinity News and Events

A group of researchers from Trinity College, Dublin, Ireland, and their international colleagues, have shown how relative isolation on the small Mediterranean islands of Malta (and neighbouring Gozo) produced distinct genomes in the population, due to a combination of the 'founder effect' and a small population reduced at time to just a few hundred inbred individuals.

Contrary to current thinking, which sees oceans as highways at the time, allowing migration and mixing more easily than travel overland, this result suggests that over the period in question, the Mediterranean acted as a barrier to isolate the population of Malta, consequently they failed to acquire some of the genetic signatures that mark migration across the rest of Europe at the time.

Analysis of the genome of ancient (4500–5000-year-old) individuals from a cave burial at the Xagħra Circle on Gozo, compared to the genomes of individuals of the same age from burial sites around Europe, show evidence of a small population numbering in the hundreds and of inbreeding, which is to be expected of a small, isolated population. One of the individuals examined turned out to be the offspring of second-degree relatives.

More Bad News for Creationists - Their Putative Designer Designed Death and Suffering, Allegedly.

Buck Scientist Uncovers Clues to Aging in Mitochondria
For the want of a better answer, Bible-literalist creationist will tell you that before Adam and Eve and 'The Fall' there was no death in the world and that death is the result of 'sin', not designed by their god at all, so their god can't be held responsible for all the lethal organisms that cause so much ill health, death and suffering in the world. They never manage to explain where the food Adam and Eve ate was alive during the whole of the eating, digestion and metabolism of it though, or whether their god made an exception in that case and allowed a little bit of death, just not human death.

Now, however, they have some more mental gymnastics to perform with the discovery that it is the mitochondria in all our cells that are responsible for aging - a process that leads ultimately to death unless illness of some sort intervenes. Scientists have known about this for some time, but a team of scientists from the Buck Institute for Research on Aging have worked out how it happens. Mitochondria, the powerhouses inside every eukaryote cell, are believed to be the descendants of a bacteria related to rickettsia which became incorporated with other organelles inside prokaryote cells.

The mitochondria in our cell still have their own DNA and replicate inside our cells, although much of their original genome has been incorporated into the cell nucleus. Because only the head of the sperm penetrates the egg at fertilisation and the head contains no mitochondria, we get all our mitochondria and so all our mitochondrial DNA from our mother and none from our father.

Basically, aging is caused by imperfect mitochondrial replication which is accumulated over the years until the mitochondria start to malfunction. Because they have given up some of the DNA into the cell nucleus, they need to reactivate some of it and import the products of it before they can replicate themselves, and this is where the process begins to go wrong, according to the Buck team.

The Buck News release explains what the team led by Buck Fellow Chuankai (Kai) Zhou, PhD, has discovered:

Evolution News - Tracing Our Cousins the Denisovans

Views of the TNH2-1 specimen.
a. Occlusal, b. inferior, c. mesial, d. distal, e. buccal and f. lingual

Ancient tooth suggests Denisovans ventured far beyond Siberia.

Until recently, the archaic humans, the Denisovans, cousins of the Neanderthals and probably cousins to modern humans, were known only from a few fragments of bone and teeth from a single site - the Denisova Cave in Siberia. One fragment turned out to be from a girl who was the child of a Denisovan father and a Neanderthal mother, showing that the two species co-existed and interbred, at least in Siberia.

Since then, there has been increasing acceptance that, because up to 5% of the genome of many people from South East Asian and Oceania, including Native Australians and people from Papua-New Guinea, is Denisovan DNA, Denisovans probably occupied South East Asia and interbred with modern Homo sapiens as they migrated to and through it.

There was also the intriguing discovery that the genes that help the inhabitants of the Tibetan Plateau live at high altitude were from Denisovans. The initial assumption was that they must have been acquired from people from lower altitudes because Denisovans would probably not have lived on the Tibetan Plateau. This would have meant that the Denisovans must have evolved these genes for a different purpose, possibly related to prolonged physical exertion, and that modern humans exapted them for high altitude survival.

Creationist mode:

Creationism’s beloved malevolence is going to have its work cut out it it is to outdo bio-medical science in their search for a definitive cure for the COVID-19 virus it created to cause the current COVID-19 Pandemic. So far, it has come up with several variants, the latest being the Omicron variant that is much more contagious than earlier variants, but, at least in a population where a large proportion of the people have been vaccinated, is mostly, though not always, a relatively mild infection.

Nevertheless, it has managed to achieve nearly 6.3 million deaths worldwide, 1 million of them in the USA where, due to the incompetence and narcissistic Dunning-Kruger stupidity of the president when the pandemic started and was most dangerous in 2020, and because of the opposition to measures to control it by fundamentalist Christians and the super spreader events they insisted on holding in their churches, deaths were far in excess of anything seen in most other advanced economies.

But now, a collaborative effort between scientists at the Scripps Institute and scientists in Italy and France may have found an antibody to the SARS-CoV-2 virus that not only treats and prevents known variants of COVID-19 but will probably be effective against future variants. The antibody is currently undergoing stage II/III clinical trials in Italy. The antibody, known as J08 was isolated from the blood of people who had recovered from COVID19 by scientists at the Scripps Institute and Toscana Life Sciences.

The question creationist devotees of the magic, pestilential sky man whom they believe designs these things, is just how is it going to find a way round this new prevention/treatment so it can continue the chaos and suffering it created? Only time will tell.

Evolution News - Ecology Before the 'Cambrian Explosion'

Creationists are fascinated by the so-called Cambrian Explosion, believing it to have happened over a very short time span and claiming it to be evidence of spontaneous creation of a wide variety of body plans. Of course, it took place over tens of millions of years and was preceded by the Ediacaran biota in which a number of novel body plans evolved in the second major wave of multicellular evolution.

Now, According to a study by Rebecca Eden, Andrea Manica1 and Emily G Mitchell of the Zoology Department, Cambridge University, UK, published today in the open access online journal, PLOS Biology, these early animals formed complex ecological communities more than 550 million years ago, setting the evolutionary stage for the Cambrian explosion.

The Ediacaran period is itself divided into three periods of evolutionary radiation, named after the locations where representative fossils have been found: the Avalon, White Sea and Nama radiation. The Avalon (575-565 million years ago), shows relatively limited ecological and morphological diversity, unlike the White Sea radiation which shows a large increase in morphological diversity, including probable bilateralism and with it an increase in ecological diversity and environmental influence. Some this was followed by a mass extinction leading to a loss of taxonomic diversity but the evolution of biomineralization, such as shells, in the third, Nama, radiation.

Biomineralization implies the need for protection and that implies the prior evolution of motility and predation and the beginnings of evolutionary arms races between predator and prey, and with that would have come environmental pressure to evolve sensory organs such as eyes. Predation also requires digestive and excretory systems.

Evolution News - How the Environment Made a Difference with Penduline Tits

Eurasian penduline tit, Remiz pendulinus

Chinese penduline tit buries eggs to prevent them from blowin’ in the wind | Science Linx News | Science LinX | University of Groningen

First off, if you came here attracted by the title, hoping to see something about large busty substances, you're in the wrong place. This is about a couple of closely related birds known as the Eurasian and Chinese penduline tits and about how subtle differences in their environments can cause differences in behaviour that act as barriers to hybridisation and so reinforce the evolving divergence into different species. If you're so shallow as to be looking for the former on line, you're probably too shallow to be interested in the latter.

The Eurasian penduline tit, Remiz pendulinus, is so called because males build a relatively large, dangling (penduline) nest on the end of thin willow branches or reeds, often over water. He then tries to attract a female to use the nest and, if she approves, he mates with her, and she begins to lay a batch of eggs over the next 14 days but won't permit the male to enter the nest. This choice of location is probably to make it difficult for predators to reach the nest.

The strange thing is each day she covers the eggs in the bottom of the nest before going off to feed herself. This is thought to be due to inter-sex rivalry because either one or the other parent is going to take responsibility for the incubation of the eggs and rearing the chicks and the female needs the male to hang around to mate with her and the male needs her to stay and use his nest so his offspring are in the eggs she lays.

When the batch of eggs is complete, the female, more often than not, incubates them and the male leaves to find another mate, but frequently, it's the female who leaves the male to do the incubation and rearing. Very occasionally, neither parent takes responsibility, and the nest and eggs are abandoned. But the male won't start to incubate the eggs until the batch is complete. Burying the eggs is thought to be an evolved strategy for keeping the male interested until the batch is complete.

Chinese penduline tit, Remiz consobrinus

However, a closely related species, the Chinese penduline tit, Remiz consobrinus, has a different pattern of behaviour. The make builds the next in the same way and in a similar position to his Eurasian cousin, and attracts a female to use it. However, she doesn't exclude him from the nest but they both roost in it together at night, and both sexes share responsibility for incubation and rearing the chicks. But, like her Eurasian cousin, the female Chinese penduline tit still assiduously buries her eggs every day. The question is, if this isn't due to inter-sex rivalry as with the Eurasian species, what is it due to? The answer has turned out to be due to subtle environmental differences.

To investigate this difference and the lack of aggression between the sexes by which the Eurasian female keeps the male from entering the nest while she is laying her batch of eggs, Jia Zheng, who had completed her master’s degree under Professor Zhengwang Zhang, from Beijing Normal University, and was now completing her PhD at the University of Groningen, conducted a number of experiment to test out various hypotheses.

The Groningen University News release explains how she went about it:

Malevolent Designer News - Creationism's Favourite Malevolence Suffers Another Blow From Science

Congenital melanocytic nevus.
These can be very large and often involve the head, face or genitalia.

Skin drug treatments may regress dangerous birthmarks and prevent melanoma

Creationist mode:

The malevolent designer that creationists worship must be getting really pissed off with modern bio-medical scientist, the way they keep finding ways to combat the nasty things it designs to increase the suffering in the world, and all because someone scrumped one of its apples, allegedly.

Fresh from science's partial victory over the SARS-CoV-2 virus with which the divine malevolence caused a major pandemic, killing millions, ruining economies and businesses and making even the survivors suffer long-term complications, we have news that scientists led by investigators at Massachusetts General Hospital (MGH), MA, USA may have come up with a treatment for a rare form of melanoma that about 20,000 babies a year are born with.

The congenital melanoma is usually in the form of a large mole or 'giant nevus' that covers part of the face, head or other parts of the body and carries a very high risk of becoming malignant. Because of the high risk of malignancy, the treatment up to now had been surgical removal, which was not always successful in that the melanoma could recur, and which often left a large, permanent scar. Congenital giant nevi are normally caused by a mutation in the gene NRAS, which, as any intelligent [sic] design creationist will tell you, only happens by design.

QAnon/COVID Conspiracy News - The Flights of Fancy Go Stratospheric

"Covid-19 is not a virus, it's snake venom" [sic]

The King Cobra Venom Pandemic: Stew Peters Unveils a New COVID-19 Conspiracy Theory | Right Wing Watch

It's amazing how, the more QAnon's ludicrous conspiracy theories are debunked, the more risible they became in trying to justify them, like toddlers caught with their hands in the cookie jar, rather than admit the game's up and they've been rumbled.

The even more amazing thing is that adults, even adults holding responsible positions, like Representative Marjorie Taylor-Green (R-GA 13) and Senator Doug Mastriano (R-PA 33) continue to fall for these tactics.

One example of how far into the stratosphere QAnon conspiracists have gone in the justification for opposing measures to mitigate the COVID-19 pandemic, which is about to achieved its millionth American death, on the grounds that it's all a plot, somehow linked to a Satanic, cannibalistic paedophile, deep state conspiracy run by Hillary Clinton, Barak Obama and the Pope, and including Bill Gates, Andrew Faucci and others, is the so-called 'explosive report' by medical quackticioner, Dr. Bryan Ardis.

His 'explosive' report which he revealed on the far right Stew Peters Show, is that the SARS-CoV-2 virus that causes COVID-19 is not a virus at all but a modified snake venom which is passed on deliberately in drinking water. Seriously!

Here is how he arrived at that conclusion, not by analysis of drinking water, or by subjecting samples of the virus to biochemical analysis, but by a form of logic of which any self-respecting toddler might be proud, until they grew up enough to cringe in embarrassment at their childish thinking.

Here is his 'reasoning':

SCOTUS Now Represents Only a Small Minority of American Religious Extremists.

Attitude towards abortion by religiosity and political leanings. States set to make abortion illegal in all circumstances will be complying with the opinion of Americans who attend church every week, especially Republicans.

Personal Religiosity and Attitudes Toward Abortion

The evidence from Gallop is that, if SCOTUS as expected overturns the 1973 ruling in Roe v Wade and allows the criminalisation of abortions in all or most cases, they will be empowering states to impose the views of a small minority of religious extremists on the rest of America, as the following charts show.

SCOTUS, whose prime purpose is to uphold the Constitutional constraints on government action, will be explicitly endorsing a flagrant imposition of Conservative Christian dogma by incorporating it into state laws.

On every measure, the opinion that abortions should be illegal in all circumstances - including where pregnancy is the result of rape or incest or the woman is very young, and even when there is severe foetal abnormality such that independent life will be impossible or there is a serious risk to the woman's life - is an opinion not shared by most Americans. It's not even the majority opinion of those Americans who go to church every week.

Ancient DNA maps ‘dawn of farming’


The flood of evidence that YECism and Creationism are notions (I won't grace them with the scientific term, 'theories') in crisis continues with news that two of the largest assemblages of ancient human genomes have revealed that the origins of European farmers was in Turkey, but that population originated many thousands of years earlier from diverse hunter-gatherer populations in Europe and Asia.

Of course, there is absolutely no evidence that all humans are descended from a single founder couple who lived just a few thousand years ago in the Middle East, as creationism's favourite myths claim.

The advances in recovering high quality genomes from ancient remains would be terrifying creationist cult leaders if they weren't safe in the knowledge that their dupes would never dream of checking facts or reading scientific publications in case they had to admit they could be wrong, so articles in science magazine such as Nature or New Scientist will go unnoticed and ignored.

The evidence in question was published in two open access papers in Cell and BioRxiv a few days ago. These works build on the 2016 findings by Lazaridis, Iosif, et al, who showed that:

…the earliest populations of the Near East derived around half their ancestry from a ‘Basal Eurasian’ lineage that had little if any Neanderthal admixture and that separated from other non-African lineages before their separation from each other. The first farmers of the southern Levant (Israel and Jordan) and Zagros Mountains (Iran) were strongly genetically differentiated, and each descended from local hunter–gatherers. By the time of the Bronze Age, these two populations and Anatolian-related farmers had mixed with each other and with the hunter–gatherers of Europe to greatly reduce genetic differentiation. The impact of the Near Eastern farmers extended beyond the Near East: farmers related to those of Anatolia spread westward into Europe; farmers related to those of the Levant spread southward into East Africa; farmers related to those of Iran spread northward into the Eurasian steppe; and people related to both the early farmers of Iran and to the pastoralists of the Eurasian steppe spread eastward into South Asia.

Well, I'll leave you to fill in the obvious punchline, but Barton epitomises the old adage that when you show the world you know you need to lie for your faith, you show the world you know your faith needs fools to believe falsehoods. As Mark Twain said, "Lying is trying to fool someone into believing something you know ain’t so!"

The question is, why does David Barton and his extremist Christian supporters need Americans to believe something they know ain’t so? The answer is because they don't want them believing things they know are so, of course.

The origin of life: a paradigm shift - LMU Munich

It doesn't seem to have dawned on creationists who forlornly claim, despite the daily torrent of evidence to the contrary, that the Theory of Evolution is a theory in crisis. Far from the TOE being a 'theory in crisis', the reality is that it's the childish notion of creationism that's in crisis and which is being increasingly rejected even by religious people as a valid explanation for how life diverged. It's only by creative misrepresentation of the data, or by dismissing it out of hand, that creationist frauds are still able to pull the wool over the eyes of their credulous dupes, to maintain their cult’s superstitions.

One of their mainstays as an 'argument' which they invariably fall back on when confronted with unarguable evidence for evolution by natural selection and other mechanisms, is that none of the mechanisms explain the origin of 'life' itself (abiogenesis, life from non-life'), and without that, evolution would have nothing to work on. It is, of course, irrelevant to the mechanisms by which life diversified once replicators did get going, but, as usual with childish notions, the relevance of using the false dichotomy fallacy is lost on creationists who lack the critical thinking skills to spot the trick, and few if any of them could define the term 'life' in a scientifically meaningful way, anyway, so assume it means some magic ingredient that separates organic' molecules from inorganic ones. It is one of the last remaining gaps which they insist must contain their god and their belief is that, of all the gaps closed by science, this will be the one where a god is found. Their ever-shrinking little god has degenerated to the size of this one remaining gap. The magician that magicked 'life' from non-life and made them 'speshul'.

There are, of course, many possible alternative explanations for how a simple replicator could have got going and, indeed, there doesn't even need to be a single explanation since two or more replicators could have got together early on. If the result had given them an advantage over remaining separate, then this symbiosis would have been almost inevitable.

One of the more popular hypotheses amongst biologists is the 'RNA world hypothesis' that says, because RNA is still the functional unit of biological activity and it is simpler than DNA, it probably came first and DNA followed on as an evolved improvement, acting as RNA's data store and so became the functional organ of inheritance of genetic data.

This is the idea currently being expanded by a team at the Ludwig-Maximilians-Universität München, Germany. Their work has just been published, open access in Nature. They believe they have solved one of the outstanding problems with the theory - how RNA began catalysing the production of chains of amino acids to form peptides and short proteins without the peptides it codes for - a classic chicken and egg conundrum.

Like all chicken and egg conundrums, if this scenario is correct, it turns out that neither of them came first; they both emerged simultaneously and part of a developing complex out of simple pre-existing precursors.

I thought devotees of creationism's malevolent designer might like to read about an astonishingly successful organism it allegedly created. It is the organism known to medical science and biology as Toxoplasma gondii, the organism responsible for the disease, toxoplasmosis.

According to the WHO over 1 million people in the European area alone become infected by it and, according to Professor Justine R. Smith, Professor of Eye & Vision Health, Flinders University, Australia and Assistant professor João M. Furtado, Assistant professor of Ophthalmology, Universidade de São Paulo, Brazil, writing in The Conversation, 30%-50% of the world's population could be infected by it, making it the most successful pathological organism known. Once infected a person carries it for life and it is one of the most zoonotic organisms, capable of infected almost any animal or bird.

Unintelligent Designer News - More on the Blunder That is RuBisCo

Photosynthesis unaffected by increasing carbon dioxide channels in plant membranes | RIPE

Readers may recall how I wrote recently about the enzyme RuBisCo, and how, if they understood its significance, it would be a major embarrassment for devotees of creationism's putative intelligent [sic] designer. To give it it's full chemical name, ribulose-1,5-bisphosphate carboxylase/oxygenase is probably the least efficient enzyme in all biology and yet is absolutely essential for the energy almost all living things ultimately depend on.

It is responsible for 'fixing' the inorganic carbon in atmospheric carbon dioxide (CO₂) as the first stage in building the carbon chain that is the backbone of the organic sugar, glucose, which is the end product of photosynthesis, along with free Oxygen (O₂) as a by-product.

Indeed, so inefficient is RuBisCo that it is the reason there is so much green in the world, wherever there are growing plants. RuBisCo manages about 4 reactions a second against the hundreds or thousands of reactions that most other enzymes are capable of, and, because it frequently mistakes a molecule of O₂ for one of CO₂, it frequently wrecks the process and causes a loss of carbon. It can also go wrong and produce xylulose-1,5-bisphosphate which actually poisons it!

Because of this inefficiency, there is great pressure on scientists to come up with an alternative, or to develop an improved version, in order to increase food production, and, to that end, multiple universities and research institutes have established the RIPE Project, led by the University of Illinois, USA in partnership with The Australian National University, Chinese Academy of Sciences, Commonwealth Scientific and Industrial Research Organisation, Lancaster University, UK, Louisiana State University, USA, University of California, Berkeley, USA, University of Cambridge, UK, University of Essex, UK, and U.S. Department of Agriculture, Agricultural Research Service.

But one of the programs run by RIPE has just reported a failure. The researchers at the Division of Plant Sciences, Research School of Biology, The Australian National University, Acton, ACT, Australia, had been hoped that, if they could improve the supply of CO₂ to RuBisCo, they could improve its efficiency. However, they discovered that the limitation was not the availability of CO₂ itself but the ability of RuBisCo to utilise it that was the bottleneck in the process.

Bali-like temperatures in Wyoming? Fossils reveal tropically hot North America 95 million years ago | University of Michigan News

Gullible fools who have been conned into believing, despite all the evidence showing otherwise, that planet Earth is just a few thousand years old, for no better reason than their mummy and daddy had been fooled into believing it, will need to ignore this evidence as well.

It is evidence that not only were fossils of highly evolved species being laid down in Wyoming, USA, 95 million years ago, but that the climate there at that time was more like that in tropical regions of Earth today.

The new study, by researchers from the University of Michigan shows that much of western North America, 95 million years ago, was covered by a shallow sea as warm as today’s tropics. The existence of this sea coincided with the "Cretaceous Thermal Maximum", one of Earth's hottest periods in the past 100 million years.

As we have seen before, most of these nasty little organisms that creationists believe were created by their favourite god, have been designed to evade or even suppress their host's immune system so they can make life as miserable, or as short, as possible.

A good example of this, and an example of the inventive genius of anything that designed it, is in fact Trypanosoma cruzi, the microorganism that causes Chagas disease, which affects millions of people in Central and South America, causing thousands of deaths every year. Researchers at the Karolinska Institutet, Sweden, have discovered just how brilliantly this parasite has been designed so it can continue to do what it was designed to do. They have shown that it can form new variants from hybrids of different strains that are often better at circumventing the immune system and causing disease.

As the Karolinska Institutet news item announcing the team's publication of their findings in the online journal, eLife, explains:

Malevolent Designer News - How a Mutation Made Us More Susceptible to Cancer

A single genetic mutation made humans more susceptible to cancer | New Scientist

Creationist mode:

Creationism’s favourite divine malevolence could have given humans the same protection from cancer that it gave to elephants, but it chose not to.

Instead, it gave us a mutated version of a gene that makes us more likely to develop life-threatening cancers when the replication mechanism it designed for our cells, goes wrong and the faulty DNA doesn't get repaired. This replication mechanism, where the entire genome is replicated even though most cells will use only a small fraction of it, is necessary because the designer used the same method for us multicellular animals that it created for single-celled organisms, so being massively wasteful and increasing the danger of something going wrong, of course, but that's a slightly different issue.

I have more to say on this phenomenon in my popular, illustrated book, The Malevolent Designer: Why Nature's God is not Good

What scientists have recently discovered is that the gene, BRCA2, which plays a key role in repairing the DNA when it isn't replicated properly, has been modified in humans to make it less effective at doing what it was designed to do in other mammals, including chimpanzees. This repair mechanism was already far less efficient than that in elephants which get multiple copies of these repairing genes, so, although they have very many more cells than us and so very many more cell replications as they grow, they very rarely get cancers.

Even in our closest relative, the other great apes, cancers are relatively rare. Between 1901 and 1932, of the 971 non-human primates that died in Philadelphia Zoo, only 8 were found to have tumours on autopsy. so there is no doubt that humans, supposedly the favourite creation of creationism's favourite creator, are designed to get cancers more than most mammals and the decision to design us that way was a choice.

Creationist must believe, because they are obliged to, that this change in the BRCA2 gene can't have been accidental because nothing happens in nature without the intention and involvement of their magic creator, so we can only assume it wants us to get cancer.

Creationist mode:

Now to the science, which, unlike creationism and the childish notion of intelligent design, makes sense of the facts:

Unintelligent Designer News - Another Arms Race between Bats and Owls is Another Problem for Batty Creationists

Greater mouse-eared bat, Myotis myotis

Bats mimic the sound of bees and hornets to scare away predators | New Scientist

Italian scientists have recently discovered a fascinating example of Batesian mimicry, using sound rather than colour and shape, to deter predators.

Batesian mimicry is where a species comes to resemble a harmful or distasteful species although being harmless and edible itself. Examples are the beetles and butterflies that resemble wasps, or the eyes on a butterfly's wings that resemble the eyes of a predatory animal. These often result in arms races where the predator evolves to be able to tell the difference, but the prey then evolves to improve the mimicry.

The phenomenon of arms races is a subject most intelligent [sic] design creationists understandably steer well clear of. They are almost invariably features of host-parasite and prey-predator relationships. A prey species will benefit from any changes that improve its ability to avoid being prey and a predator will benefit from any changes that improve its ability to catch its prey, so arms races are major drivers in evolution.

It's difficult to see how a single designer switching back and forth between two species, seeing every solution it has just designed for one species as a problem to be overcome for the other species, can possibly be regarded as the behaviour of an intelligent designer. Creationists, by the dogma of the religion they invariably subscribe to, are forbidden from explaining this as the acts of two or more competing creators, of course, so are obliged to continue to present their favourite god as, frankly, a rather stupid amnesiac, not knowing from one day to the next what it is supposed to be achieving and forgetting what the solution it designed yesterday was all for.

I cover these evolutionary arms races and the problem they present for intelligent [sic] design advocates in my popular book, The Unintelligent Designer: Refuting the Intelligent Design Hoax.

But enough of the problems creationists have in sustaining their childish superstition and the absurd mental gymnastics they need to perform.
