Stupid Design - Cannibal Caterpillars


Beet armyworms on tomato leaves. A choice of nasty-tasting leaves or juicy sibling!
Plants under attack can turn hungry caterpillars into cannibals

I almost laughed out loud when I read this one. Not only is it a lovely little piece of biology and so easy to explain in terms of genetic evolution but it's also an example of the mind-numbing stupidity of any sentient designer who had to come up with such a design to solve a problem it had designed!

Abstract
Plants are attacked by myriad herbivores, and many plants exhibit anti-herbivore defences. We tested the hypothesis that induced defences benefit tomato plants by encouraging insects to eat other members of their

Zebra Finches Show How Evolution Works

Zebra finch, Taeniopygia guttata.

Courtship song preferences in female zebra finches are shaped by developmental auditory experience | Proceedings of the Royal Society of London B: Biological Sciences

A paper published recently in Proceedings of the Royal Society B by researcher from McGill University, California, USA, illustrates a couple of interesting aspects to evolution and how species diverge.

The team found that zebra finches (Taeniopygia guttata) reared in the absence of their fathers do no react in the same way to male courtship songs as those raised by both parents.

Now, this in itself might not be particularly important apart from one thing - female sex selection. Females normally select the best singers as their mates and there is growing evidence that the best singers are also the healthiest and fittest males. Females who don't have the ability to discriminate lose out in the competition for the best mates. This, after all, is probably one of the main drivers for the evolution of female sex selection.

Suffer Little Children - For Money

'Pope's hospital' put children at risk as it chased profits

If you're a Catholic and you have a sick child, you know really that prayer doesn't work so you send them to a hospital where they apply science instead, unless of course it's the 'Baby Jesus' children's hospital, run by the Vatican with branches throughout Italy.

These hospitals were dirty, badly run money-making organisations that had little to do with curing and caring or sick children. Corners were cut, safety protocols were ignored and sick children were suffering as a result.

In typical Vatican style, a 2014 report on the secret three-month investigation following complains from staff and patients' families, was itself kept secret. Some of the recommendations were allegedly implemented, but many were not.

What A Carry On At The Vatican!

Msgr. Luigi Capozzi.
Fun-loving Vatican insider with influence.
The truth about the Vatican sex-and-drugs scandal | Catholic Culture

It's reassuring to learn that in the Vatican at least, some things just never change. Everything is carrying on much as it was in the 16th Century.

You might have missed the latest piece of gossip because it seems such events are now scarcely worthy of the epithet 'news'. There simply isn't anything to justify several column inches of news print of several minutes of airtime to report something that scarcely raises an eye-brow these days. It was just another gay sex and drugs party in the Vatican involving a middling official with friends and considerable influence in high places. It was just another example of the hypocrisy we have come to expect of the Catholic clergy.

Now, what would be news is if we went a whole year without another sex and drugs, financial or rent-boy scandal at the Vatican, or even (not that this is even remotely possible) a whole year without another child sexual, emotional and physical abuse scandal involving Catholic priests and/or nuns complete with institutionalised cover-up or even active facilitation of it, somewhere in the world

How Creationists Lie To Us - Carbon Dating Hoax


Diagram of production of carbon-14 in the upper atmosphere by reaction of neutrons with nitrogen, and of the subsequent incorporation of carbon-14 into the biosphere.
Having been called a liar by a creationist for saying there were no scientifically valid examples of 14C dating of dinosaur fossils, and then, despite his claim that there were 'lots' of them, being treated to him prevaricating and deflecting for several days before failing to provide any such examples even after numerous requests, I decided I would look closer at this claim.

First a brief background. For more detail see this article by A. J. T. Jull, a research scientist at the NSF Arizona AMS Facility and Department of Geosciences, University of Arizona, in Tucson, Arizona, USA.

Carbon-14 (14C) dating is, when done correctly on carefully decontaminated specimens, an accurate method of dating an organic specimen within well-known limits of confidence and within a well-defined date range. The date obtained will always be expressed as x years BP ± y years.

Doing it correctly not only means careful decontamination but also understanding its limitations, the major one being the date range over which it is reliable, why this limit exists and, importantly, exactly what carbon you are measuring in the sample and how it got there.

Not all carbon is organic in origin and not all carbon in archaeological samples is derived from the original organic carbon. For example, although carbonates may be present in the mineralised bones of which fossils are made, this does not mean it came from the original bone. After all, fossils will contain large amounts of silicates but bone does not normally contain silicon. The minerals in fossils are replacements for the original material, not necessarily the products of it.

Another Gap Closes. No God Found!

Stem caecilian from the Triassic of Colorado sheds light on the origins of Lissamphibia

Scientists working for the Department of Integrative Anatomical Sciences at the Keck School of Medicine of USC have closed another one of those gaps in science that creationists scrabble around in, desperately searching for as somewhere to fit their god.

Although no serious biologist these days sets out to confirm evolution or to refute creationism, papers such as this one do that quite incidentally because they report on the reality of the natural world and objectively assess the evidence. Quite naturally, this refutes any notions such as creationism which are not based on real-world evidence.

Mapping Human Evolution Out of Africa

Neanderthal
Out of Africa; new research explores drive behind early humanity's travels across the world - Royal Holloway, University of London

Interesting news came a few days ago from Royal Holloway, University of London, that a new research project is to start next month, aimed at mapping the spread of humans out of Africa and across the globe, to occupy all major landmasses other than Antarctica. The research is financed by a £450,000 grant from Leverhulme Trust.

As the Royal Holloway press release says:

Creationism's Nightmare - Abiogenesis!

Evidence for early life in Earth’s oldest hydrothermal vent precipitates : Nature : Nature Research

Science is moving closer to an explanation of a process whereby the earliest proto-cells could have developed naturally on Earth. It's looking increasingly as though the best explanation of where suitable conditions could be found - in the rock precipitates around hydrothermal vents on ocean floors - is the right one.

It's also looking as though the process got going even earlier than we thought - when Earth was just few million years old, if the interpretation of the evidence presented in this paper is correct. It is strongly suggestive that the process may have got going at least 3.77 billion and maybe even 4.28 billion years ago.

The evidence was found in rocks from the Nuvvuagittuq belt in Quebec, Canada, which are believed to have been formed by precipitation around seafloor-hydrothermal vents.

An experimental demonstration that house finches add cigarette butts in response to ectoparasites - Suárez-Rodr-guez - 2017 - Journal of Avian Biology - Wiley Online Library

Here is yet another fascinating example of the ingenuity of biological adaptability - and an example that should make any self-respecting intelligent design advocate cringe with embarrassment.

Constantino Macías Garcia at the National Autonomous University of Mexico, and his colleagues have been studying a curious phenomenon observed in the Mexican urban house finch (Carpodacus mexicanus) in which they collect cigarette butts and place then in their nests. There was inconclusive evidence that the effect was to deter parasitic ticks and other nest parasites so they designed a simple experiment to settle the matter. It was strongly suspected that nicotine and other chemicals in the butts acts as a deterrent to parasites. House sparrows (Paser domesticus) have also been observed to use the same strategy.

Anglican Church Colluded in Abuse Cover-up.

Peter Ball
Groomed and abused 18 vulnerable boys and young men.
Church 'colluded' with sex abuse bishop Peter Ball - BBC News

It's ironic really! Just when I go on holiday to Italy, the centre of the organised global Catholic paedophile ring that we discovered existed some ten to fifteen years ago, a similar, though smaller, scandal breaks in England and it's not even involving the Catholic Church!

This one involves a form Anglican bishop, Peter Ball, and a former Archbishop of Canterbury, Lord George Carey. Peter Ball had been Bishop of Lewes and then Bishop of Gloucester during which time he groomed, exploited and sexually abused eighteen young men and boys who went to him seeking spiritual guidance. He was jailed for thirty-two months in October 2015 for these offences but was released last February after just sixteen months.

Now a report into the church's handling of the affair, ordered by the current Archbishop of Canterbury, Justin Welby, and chaired by the former chief executive of Camden Council, Dame Moira Gibb, makes harrowing reading, according to Welby. Carey as Archbishop of Canterbury, a cabinet minister and a high court judge all conspired to protect Ball and wrote letters to the police and the Crown Prosecution Service in his defence.

Cretaceous Bird Mocks Creationists

Bird caught in amber 100 million years ago is best ever found | New Scientist.

It's not often we get to look at creatures from 100 million years ago, displayed in such detail. Normally we have to make do with distorted stone fossils which been subjected to all sorts of pressures and stresses, leaching by water and slow replacement by minerals over centuries. It's sometimes surprising that very much detail has been retained at all.

Preservation in amber is quite another matter, however. The specimen is trapped and coated in resin in a matter of minutes and sealed quickly away from any bacteria other than those trapped with it, and isolated from oxygen, other than the minuscule quantities that can slowly diffuse through the amber. It's almost as though the specimen has been sealed in a time capsule.

Yet Another Of Those 'Missing' Transitional Species

The African cynodont Aleodon (Cynodontia, Probainognathia) in the Triassic of southern Brazil and its biostratigraphic significance

At one time it became quite tedious writing yet another article about yet another of the transitional fossils that creationists dogma says aren't there. Who wants to read more or less the same thing several times a week with only the details changed? The problem of course is that every fossil is transitional because each represents a snapshot in time of a species that is evolving and changing over time.

But this latest one is interesting in that it is clearly transitional not between one genus and another or even between one family and another but between two or three major taxons. It is transitional between the reptiles and the mammals and comes close to the stem amniote that had earlier split from the amphibians to give rise to the land-based egg-laying tetrapods. This group went on to give rise to reptiles, mammals, dinosaurs and birds. The current consensus in palaeontology is that the amniotes probably radiated from a single ancestral species that had evolved an egg able to be laid out of water, so breaking the dependence of the amphibians on water.

More Nastiness From The 'Intelligent Designer'

Zombie soldier beetles: Epizootics in the goldenrod soldier beetle, Chauliognathus pensylvanicus (Coleoptera: Cantharidae) caused by Eryniopsis lampyridarum (Entomophthoromycotina: Entomophthoraceae):

The 'Intelligent (sic) Designer' is ever inventive in its sheer malevolent nastiness, continually coming up with ideas that would have been a credit to a Medieval torturer for the Spanish Inquisition or the organisers of 'entertainments' for a bloodthirsty Roman amphitheatre audience.

This one in particular is the epitome of casual malevolence and indifference to suffering. Its design turns a beetle into a zombie just before killing it, and then grotesquely reanimates its corpse so it can do it all over again to more victims.

Sadly, the copyright holders, Elsevier, want to charge me £22.43 to save you the trouble of clicking on this link, to read in the Journal of Invertebrate Pathology how the team from the University of Arkansas and Cornell University, led by Donald C. Steinkraus, discovered how it works.

The victim is the goldenrod soldier beetles, Chauliognathus pensylvanicus which survives by eating the flowers of frost aster, Symphyotrichum pilosum, common boneset, Eupatorium perfoliatum, and Canada goldenrod, Solidago canadensisnormally. They normally mate on top of a flower. It seems, if you subscribe to the notion of intelligent design, that the intelligent designer (who isn't God by the way, so it isn't religion it's biology and should be taught in schools, but he just happens to be identical in every way to the god of a literal interpretation of the Bible) spotted the opportunity for a bit of fun, so He it designed a fungus, Eryniopsis lampyridarum, to infect these beetles.

When the fungus, which has been living in and consuming the female beetle, is ready it first turns its host into a zombie and makes it clamp itself onto a flower stem with its jaws, immediately before killing it. Then it makes lots of spores inside the dead female's body before reanimating it! 15-22 hours after death the female spreads her wings out wide so the spores can escape through the spiracles she used to breathe through, then her body swells, making her more attractive to males who try to mate with her, so getting infected in the process.

They they find a living female to mate with and infect her with the fungus and the cycle repeats itself.

Neat, eh?

Now, although intelligent (sic) design is 'definitely-biology-not-religion', cDesign proponentsists (sic) will normally resort to 'The Fall' to explain parasites such as this. 'The Fall' is of course a purely religious construction found in the Bible and forming the basis of Christianity, but at least this enables them to dismiss these hideous examples of, if it were the intention of a real conscious being, malevolent intent, as not their god's the intelligent designer's fault. It doesn't explain how turning beetles into zombies and then reanimating them just to spread a fungus infection to the next generation of beetles relates to some mythical event in the Bible (which of course it doesn't because it's definitely-science-not-religion, except it does) but at least it nearly gets God the intelligent designer off the hook - if you don't think too much about it.

Using real science of course, this is exactly the sort of thing evolution predicts because there is no plan, no morality and no concept of punishing anything for 'sin', simply the allele frequency changing over time to maximise the number of reproducing offspring.

Dogs and Wolves Have a Sense of Justice Too

Vetmeduni Vienna : Sensitivity to inequity is in wolves’ and dogs’ blood

To listen to religious apologists you would think there is something special about humans that sets them apart from the rest of nature.

More often than not, in addition to babbling about a 'soul' (although they don't seem to agree whether that's unique to humans or not) they will quote morality, ethics, love, compassion, and a sense of fair-play or justice as setting us about the mere beasts.

This view has repeatedly been refuted by naturalists who can show that, for example, elephants grieve over lost friends and relatives, that several animals including the other apes show compassion and empathy. Now a paper by a team from the University of Veterinary Medicine, Vienna, Austria believe they have shown that not only domestic dogs but wolves have a sense of fairness and equity.

Highlights
  • Pack-living dogs and wolves show both reward and quality inequity
  • More dominant individuals were more inequity averse for both dogs and wolves
  • Inequity conditions influenced social behaviors in subsequent interactions
  • Inequity aversion is probably linked to the evolution of cooperation in dogs and wolves

Summary
Sensitivity to inequity is thought to be an important mechanism for recognizing undesirable cooperative partners and thus crucial for the evolution of human cooperation [ 1 ]. This link may not be unique to humans, as cooperative non-human primates also react to unequal outcomes [ 2 ], whereas non-cooperative species do not [ 3 ]. Although this hypothesis has not been tested in non-primate species, studies revealed that pet dogs show a limited form of inequity aversion, responding to reward, but not quality inequity [ 4–6 ]. It has been proposed that this primitive form of inequity aversion was selected for during domestication and thus absent in their ancestors, wolves. Alternatively, wolves, which hunt, raise pups, and defend their territory cooperatively, are similarly inequity averse as non-human primates, or at least to the same degree as pet dogs. Testing similarly raised and kept pack-living dogs and wolves, we found both to be inequity averse when their partner was being rewarded but they were not for performing the same action. Additionally, both wolves and dogs reacted to receiving a lower-quality reward than their partner. These results suggest that the inequity response found in pack-living dogs and wolves is comparable to that observed in non-human primates; results from studies on pet dogs may be confounded by the dogs’ relationship with humans. Consequently, our results suggest that inequity aversion was present already in the common—probably cooperative—ancestor of wolves and dogs and thus support the hypothesis of a close link of cooperation and inequity aversion.


This basic instinct in humans is of course the basis of many legal systems including English Common Law - from which the laws of most American states are derived (the exception being that of Louisiana which is derived from French Law). The Law assumes an entitlement to equal and fair treatment in a trial, including the idea that what was good in an earlier case should be good in this one - hence the Law is the body of cases. As we say in English Law, the Law if the cases; the cases are the Law.

Religious apologists have long argued that this this is what makes us 'civilised' and that the moral basis of this is God-given morals (conveniently ignoring the amoral, even immoral nature of their own god according to their holy books).

What the researchers found was that, in experiments where of a pair of dogs completed a task but only one was given a reward, or one was given a lower value reward than the other, the dog treated less fairly refused to co-operate in future experiments. The same phenomenon was demonstrated in a captive wolf pack where the response was also affected by the individual wolf's ranking in the pack heirarchy, with high-ranking dogs reacting more quickly to inequity, presumably because they were less used to being treated unfavourably.

Because a sense of equity is common to wolves and domestic dogs, it is strongly indicative that it was present in their common ancestor.

So, where does this leave the notion that somehow human's are above the animals because they are conscious, have empathy and enjoy civilising morals handed down by an invisible law-giver? It leaves it in tatters, of course. There never was any basis for this anthropocentric arrogance. Morals and ethics are evolved characteristics in social animals where teamwork and cooperation are essential for success.

The press are having one of those, "The textbooks are going to have to be rewritten" days.

Apparently, the textbooks are not just updated with the most recent findings and understanding when a new edition is published; they have to be rewritten because that one little bit of new information shows that everything we thought we knew was wrong. You sometimes wonder if the science news is written by creationists - except of course that the news media don't then make the absurdly childish leap of concluding that because one little bit of science has been revised this proves the entire body of science is wrong - about everything, so God did it!

But, in this case, the entire evolutionary story of humans now needs to be rewritten, so we are told. You might now be wondering what is this amazing discovery? Humans are not apes? Not African apes, maybe? We've evolved from guinea pigs or spontaneously generated? The truth is slightly more prosaic of course, in fact it barely rates as startling at all - interesting and thought-provoking, naturally, but startling? The 'startling' fact is some archaic human fossil remains including skulls, flint tools and animal remains found in Morocco have been dated to about 300,000 years old and may be the oldest fossil Homo sapiens so far discovered.

I Want To Tell You A Story!

How did almost nothing end up making you?

Don't tell the creationists and spoil their delusion but we've pretty much worked it out. It's not what they were hoping for!

From Chapter 10 of my latest book, "What Makes You So Special?":

From that small, unremarkable member of the Cambrian biota; those stiff little chordates that swam around amongst the trilobites and fearsome Anomalocaris with its huge, jaw–like appendages that were once thought to be a different species in their own right, big things were coming; in fact the biggest things to ever live – the blue whale. From that unpromising beginning were to evolve the fasted running animal, the fasted flying animal, birds that can soar on the wind and sing symphonies, two forms of powered flight, echolocation at least twice, a brain capable of doing calculus without realising it, and an ape that can go to the moon.

But first, it had to learn to walk on land and breathe air.

Islam is not the Problem. Faith is the Problem!

The grotesque random slaughter of innocent people, including young children, in the name of Islam, in Britain, France and Afghanistan by Muslim fanatics, and the equally grotesque murders of innocent Norwegians by the Christian fanatic, Anders Breivik a few years ago are the results not of Islam or Christianity; they are the result of faith.

They are the result of people arrogating for themselves the right to determine who can live and who should die, based on nothing but faith and the belief faith gives them certain knowledge of what a god wants, who it wants to punish - and that it requires their help in meting out that punishment.

It would be easy to condemn the deluded, simple-minded fools who carried out these acts as 'evil'; as representative of an inherently 'evil' religion or the products of inherently evil cultures, but that would be missing the point entirely.

The problem is not Islam; the problem is not Christianity. The problem is faith.

The Meaning of Information to a Flightless Cormorant

A genetic signature of the evolution of loss of flight in the Galapagos cormorant | Science

The thing about information is that it means nothing without a reader; a reader moreover that can interpret the information and give it meaning.

Try this for example. Look at the following sequence of letters and see if it means anything:

teave

The chances are, especially if you're reading this in English, it won't mean much. It's information but it doesn't have much in the way of meaning. Maybe something to do with a popular beverage? Is it an accidental typo? Leave, heave, beaver, maybe?

New Book - What Makes You So Special?

My latest book goes on sale today!

It tells your story and how the stuff you are made of came to be and found itself on a tiny speck in the cosmos where the conditions were right to make more stuff stuff that could reproduce itself.

It explains why, 3.8 million years later, you can look at the cosmos and wonder how it all happened.

This book tries to answer that question, not in the technical terms one scientist would use when talking to another but in terms that should be understandable to anyone who wants to know this amazing story - the story of you!

Like all good books it should leave you feeling satisfied but wanting more. Above all, it should leave you feeling both very special and very humble.

From Chapter 1 'Something for Nothing'
The singularity cannot have had a cause because there was nothing to cause it. It could not have exist anywhere because there was nowhere for it to exist. It cannot have had a before because there was no time for it to have been in. It did not exist in space or time because there was no space or time for it to exist in.

For all practical purposes, it did not exist. It is zero; nothing; nada; not.

And yet this nothing gave birth to the entire Universe!

How Science Works - Ancient Egyptian DNA

Geographic context, of the samples used in this study.
Ancient Egyptian mummy genomes suggest an increase of Sub-Saharan African ancestry in post-Roman periods : Nature Communications

The thing about writing science books is that the moment you publish them they start to go out of date. The reason for this is obvious to anyone familiar with how science works and how knowledge is continually improving and being refined. Creationists, with their preference for certainty, no matter how false, over truth, this continual self-checking and self-revising nature of science is both baffling and disturbing.

As though to illustrate this point, no sooner had I put the finishing touches to my most recent book, "What Makes You So Special?", and submitted it for publication, than a paper was published that answered one of the mysteries that I alluded to in it. I had briefly covered, amongst other things, the origin of the Ancient Egyptians and their part of the human story. The mystery was who exactly the Ancient Egyptians were and where they came from.

The answer has been made possible by a new technique which has enabled DNA of sufficient quality to be extracted and compared to the DNA of other human groups. There is probably a lot more yet to come from these studies, including identifying what foreign incursions there were into Egypt in ancient times.

Coming Soon - Your Story!

Several years ago I wrote a blog post based on a much earlier post I originally put in a CompuServe Forum (who remembers those?). It told the story, as I then understood it, from the Big Bang to the evolution of modern humans. I called it What Makes You So Special?

When I promoted it on Twitter it sent several fundies into a frothing rage but the reaction I got from the science and especially Atheist community was surprising. One person said it made her cry and she kept reading it over and over. Another said he's printed it out and given it to his grandson to read. A third said it had changed her life.

Several said I should add more detail and make a book out of it...

That idea had been gestating for several years, and had even suffered one false start. Now it is nearing fruition: I am about to publish the book!

The book is aimed at the curious; at those who want to know and understand a little more about how they got to be alive, here and now and who find mystery and magic wholly unsatisfactory answers.

Yet more confirmation, if any were needed, that Christianity in particular and religion in general are still declining rapidly in the UK. This report by The Benedict XVI Centre for Religion and Society, launched by St Mary's University, Twickenham, has shown that for every one person moving from no religious affiliation ('None') to affiliation with a Christian church, twenty-six leave the Christian faith and identify themselves as 'Nones'.

How Creationists Lie To Us - Zuul crurivastator

New ankylosaurine from Montana | Open Science

The discovery by palaeontologists of one of the most complete fossils of an ankylosaurine dinosaur which they have named Zuul crurivastator is interesting to creationists only in that it can be misrepresented as evidence of a very young Earth and of the idiotic notion that humans and dinosaurs co-existed. The problem of dinosaurs for creationists is that they are evidence of a very old Earth with life having gone through lots of stages with diversification and extinctions commonplace tens of millions of years before humans evolved. They thus refute the myths and invalidate the Bible's account of creation. So, creationists are desperate to mislead their followers about this evidence.

Stupid Designer - Oak Joke

It always amuses me how creationists often resort to "It's all around you! You only have to open your eyes and look!", when asked for evidence of design in nature.

The simple truth is that if you really open your eyes and look, you find abundant evidence of stupidity in 'design' in nature. Even leaving aside the obvious evidence of callous indifference to suffering which if it were evidence of intent, would also be evidence of grotesque malevolence, there is abundant evidence 'all around you' that there is only dumb, unthinking and unplanned... I was going to say stupidity, but even that implies some sort of inept intent and culpability. It's just unthinking; literally mindless!

Walking our grandson to school this morning we came across this tree in the photographs. From the leaves and bark it looks to me like a species of oak. It's not the usual English oak, so I don't know what species it is, but the species isn't important. What is important is the fantastically wasteful method is uses to reproduce. Who in their right mind would regard this as an intelligent design?

Over it's lifetime, a tree needs to produce just one tree for the population to remain stable. Just a single tree over a lifetime of maybe a couple of hundred years!

You would expect good design to be efficient design. Who in their right mind would buy bread from a baker who is so bad at baking bread that you need to buy two, let alone tens or hundreds of thousands of loaves, just to get a slice that's fit to eat?

Moral Compass - Ohio Televangelist Used Slaves

Televangelist Ernest Angley ordered to pay $388,000 for using unpaid labor at Cuyahoga Falls buffet | cleveland.com

The finest old Christian traditions are being maintained in Cuyahoga Falls, Akron, Ohio, USA!

Unfortunately, a federal judge, Benita Pearson, didn't agree that he had a right to own slaves and ordered televangelist preacher, 95 year-old Ernest Angley, to pay $388,000 to his victims. Judge Pearson ruled that Angley and his managers at the Grace Cathedral Buffet had put undue pressure on members of his church to work as volunteers in his for-profit restaurant to save money, so they were entitled to be paid for their labour.

In an astonishing letter to "The Parishes and Chaplaincies of the Church of England", the Archbishops of Canterbury and York came as close as they dared to urging Christians to vote Conservative.

This is not because Conservatives under Theresa May or any other leader have shown any compassion for the poor and sick or subscribe to any notions of the essential equality of Man, quite the opposite in fact, but because they see this as the best way to maintain and extend their 'entitled' special privileges and assumed right to discriminate against the minorities of their choice.

How Xenophobia Evolved

Overt xenophibia, used during the United Kingdom EU referendum.
Subconscious fear of infection may explain skepticism towards immigrants - ScienceDaily:

Xenophobia, one of the most irrational and destructive of human emotions, may have an evolutionary basis as a defence against infection, so argue scientists from Aarhus University, Upsala, Sweden in a published in American Political Science Review yesterday.

It is readily understandable how an aversion to excrement and putrefaction evolved, even evolving olfactory mechanisms which interpret the scents given off as repulsive. It is maybe not quite so easy to understand why some people at least overreact and are repelled by such signs of difference as physical deformity, birthmarks, skin colour and dress and yet these reactions are strong enough and commonplace enough to prevent successful integration of immigrant and refugee populations. The internal immune system, which attempts to cope with potential pathogens once they have gained access to our bodies, is supplemented by a behavioural immune system which helps prevent infection in the first place. The authors argue that this is an overreaction of a hypersensitive behavioural immune system.

Bonobos Refute Creationism!

Bonobo, Pan paniscus.

Bonobo anatomy reveals stasis and mosaicism in chimpanzee evolution, and supports bonobos as the most appropriate extant model for the common ancestor of chimpanzees and humans | Scientific Reports

A paper published a few days ago is bound to cause a frenzy of denialism amongst creationists of all varieties and not just because of the length of its title. It appears to confirm what many people have suspected for a very long time - that the closest living relative of Homo sapiens is the bonobo, Pan paniscus.

In fact, in some respects the difference between humans and bonobos is less than the difference between different varieties of creationist. Creationism has been evolving and diversifying at warp speed since its invention in the 19th century in response to the discovery by science of biological evolution.

Now the differences are so wide it's difficult to find two creationists who agree on anything very much. They can't agree on such basic as whether evolution occurs at all, whether it occurs at a fantastic speed or slowly, how intelligent an intelligent (sic) designer would need to be, how well or badly the evidence fits old religious myths, whether there is any value in scientific evidence. They can't even agree on what shape Earth is, how old it is and whether it orbits the sun or the sun orbits Earth.

Does the 'Intelligent (sic) Designer' Hate Humans?

Plague Bacteria Take Refuge In Amoebae

For those who claim to subscribe to the intelligent (sic) design notion, parasitism is always embarrassing and not something they will normally bring themselves to discuss.

Take the battles medical science is having with the zika virus, the ebola virus, the malaria parasites, antibiotic resistent in pathogens, etc., for instance. If we assume for a moment that resistance to the various treatments is by design, not evolution, then one has to conclude that the designer is on the side of the parasites and is actively trying to out-manoeuvre medical science's efforts.

This study serves as a proof of principle that amoebae can support prolonged survival of Y. pestis in the environment.

Now we have the example of one of the most devastating disease organisms ever to hit mankind - the Black Death-causing Yersinia pestis - has been 'designed' to take refuge in the common amoeba which is abundant in soil and so provides a ready safe haven for Y. pestis to hide in.

Quietly and without fuss, and quite unintentionally, science again refutes creationism.

As it often does, in fact as it almost invariably does, another piece of scientific research based on observations of the real world, incidentally refutes the primitive superstition that the Universe and Earth were created by magic just a few thousand years ago. It also refutes the myth that there was a global flood even more recently, within the written history of civilisations such as those of Ancient Egypt, China and Northern India - who all seem to have forgotten to record it or even notice that there was anything amiss.

Homo naledi is only 250,000 years old – here’s why that matters | New Scientist

Creationists now have another problem and it's not just 250,000-year-old fossils in a 10,000-year-old Universe. It's even more fundamental than that.

First, a little background:

Homo naledi is from South Africa and, like another South African hominid, Australopithecus sediba, has a mixture of very human physical characteristics and some very primitive ones. With A. sediba, the primitive characteristics are enough to place it in the Australopithecus genus and so either an ancestor of the Homo genus or a cousin of one of our ancestors.

The Little 'Hobbit' is a Big Problem for Creationists

Origins of Indonesian hobbits finally revealed:

In its slow, methodical way, science shed a little more light on one of the mysteries of the evolution of the hominid family tree - the origin of the so-called hobbit, Homo floresiensis. The remains of H. floresiensis were found in a cave in Liang Bua in the Indonesian island of Flores in 2003. Initially, they were thought to be about 12,000 years old but later analysis has pushed this back to about 50,000 years.

The mystery isn't so much now how they came to be still living in isolation up to 12,000 years ago or why they are so small, being only about 1 metre tall, but where they fit in the hominid evolutionary tree and how they got to Flores Island.

Now a team from The Australian National University (ANU) has carried out a detailed statistical analysis and

New Book With A Difference

Cover photo:
Some of the children of Fawler about to be given a ride by Fred Able, "The Donkey Man." About 1955-56.
Part of the reason I haven't been blogging quite so much in recent weeks is because I have been writing another books.

No, not another book about my usual subjects - general science, biology, atheism, religion and it's fallacies - but a much more personal book; a book about my childhood in rural Oxfordshire in the 1950s and 60s.

Of course, I cover my realisation that I was an Atheist and how my love of nature and science developed but I also cover life in general in a small agricultural hamlet. I talk about how important the countryside was to us as a playground and in particular how important the River Evenlode was to us children.

We spent the summer swimming, diving or lying half asleep with noses buried in fresh clover on the river bank and generally showing off to the local girls whose bodies were taking on strangely fascinating shapes. Some of the girls even began to wrap themselves in towels when they got changed. It was all very strange!

Give The Designer The Clap it Deserves!

Neisseria gonorrhoeae infection in the human endocervical tissue is visualized by immunofluorescence microscopy. Bacterial (red) colonization causes columnar endocervical epithelial cells to shed and lose the barrier function, which allows bacteria to enter the endocervical tissue. Frozen tissue sections were stained for immunofluorescence with specific antibodies to the apical junctional protein ZO1 (green) and N. gonorrhoeae (red) and the nuclear dye DAPI (blue).

The Intelligent (sic) Designer really does deserve a big clap! It has come up with a brilliant solution to the problem it caused by its lack of a plan!

You see, the Intelligent (sic) Designer, that imaginary being so beloved of creationists but definitely not God because that would make it religion, not science, wants to make life unpleasant for humans (for strictly scientific reasons, obviously, and nothing to do with The Fall because that's religion) so it designed nasty little organisms like Neisseria gonorrhoeae to infect them when they had sex because it doesn't like them having sex the way it designed them to.

The trouble was, in a forgetful moment, it had designed humans so they could cope with nasty little organisms like N. gonorrhoeae and not be made sick by them. Now though, it has briiantly redesigned N. gonorrhoeae so it gets around the protection if gave humans.

In an open access paper published in PLOS Pathogens today, a team of scientists led by Liang-Chun Wang of the University of Maryland, College Park, have worked out how it got around the problem it had created. It does it by exploiting the very defence mechanism the Intelligent (sic) designer designed in the first place.

Layers of Evidence Against Creationism

There is science; and there is creationism. They have nothing in common.

Science looks at evidence and bases its opinions on it. When the evidence changes, science changes its mind. How could it be otherwise when the evidence is in charge? Creationism, on the other hand, starts with opinions as dictated by a holy book and then tries to force-fit the evidence around those opinions so they look sort of sciency to the scientifically illiterate and less like irrational superstitions and magical thinking. When that fails even for the gullible credulity of creationists, the fact are simply ignored and the main problem for creationists becomes how to get away with dismissing what can be plainly seen without looking too dishonest and deluded.

Parasites Bug Creationists

Cimicid Remains Found in Oregon Caves are Oldest Ever Found – Entomology Today

Newly discovered bat-bugs from the floor of a cave in Oregon are the earliest so far found - and it's bad news for creationists, again.

Parasites are a problem for creationists for number of reasons and not just that so many creationists are susceptible to parasitic frauds who sell them spurious confirmation of their superstition for large amounts of money. It's no accident that so many creationist charlatans are multi-millionaires while the people they live off are amongst the poorest of people.

How Evolution Works - Squirrels and Pine Martens

Sometimes, evolution can produce intriguing and unexpected results. At first glance it may be hard to see why introducing a predator can result in an increase in the population of a species. This is especially pleasing when the species benefiting is a charming and endangered species, the European red squirrel and the predator is an almost equally beautiful member of the stoat family, the pine marten.

So, having been away from blogging for a couple of weeks with other distractions, it gives me considerable pleasure to write about this open access paper, albeit from 2014, which reports just that from Ireland.

Observable Evolution Over Nine Generations!

Real-time divergent evolution in plants driven by pollinators | Nature Communications.

Until a few years ago, almost all creationists had no doubt at all; evolution simply didn't happen. All living things were created in a couple of days exactly as they are today. There was no debate; evolution didn't happen because it wasn't mentioned in the Bible and that was that.

This is still the position maintained by a large number of creationists who believe the world was created just a few thousand years ago, as we see it today, and nothing has changed since.

Noses Run Counter To Creationism

Investigating the case of human nose shape and climate adaptation | PLOS Genetics

Scientists believe they have uncovered evidence that the different human nose types are at least partly or even mostly adaptations to different climates as humans spread out from our ancestral homeland in Africa.

An important function of the nasal cavity and the nasopharynx is to humidify the sir before it reaches the lower respirator tract and the lungs.

Using 3D facial imaging, the team measured the width of the nostrils, the distance between nostrils, the height of the nose, nose ridge length, nose protrusion, external area of the nose and the area of the nostrils. They found the two measures: the width of the nostrils and of the base of the nose differed between different human populations by more than would be expected from genetic drift alone. They found a positive correlation between the width of the nose and the warmth and humidity of the climate in which the populations lived.

Unintelligently Designed Epigenenetics

Creationists, especially those who try to disguise their religious cult as 'Intelligent (sic) Design' and pretend it's science, seem to be getting themselves over-excited by the relatively new science of epigenetics.

It's easy to see why, given the abysmal ignorance which characterises creationism, because it superficially seems to challenge some of the basic principles of Darwinian evolution because it appears to open up the possibility that changes acquired after conception can be passed on. This is, of course Lamarckian, not Darwinian inheritance.

Given the creationist assumption that if they can show any science to be ever so slightly wrong in any way, the entire body of science if proven false and their primitive, evidence-free superstition wins by default, they grasp desperately at epigenetics like a drowning man grasps at straws and wave it in triumph.
