Morocco Mystery Man

A composite reconstruction of what its discovers believe is the earliest known Homo sapiens fossil (from Jebel Irhoud), based on scans of multiple specimens. The virtual imprint of the braincase (blue) indicates that brain shape, and possibly brain function, evolved within the H. sapiens lineage, the scientists say.

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 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.

Declining Faith - The Fall Continues

Catholic Research Forum Reports 3 - The 'no religion' population of Britain | The Benedict XVI Centre for Religion and Society

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 so much as 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 and Slave Owner, Ernest Angley
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.

The Same Old Appeal For Special Priviledges

Archbishop of York, John Sentamu, and Archbishop of Canterbury, Justin Welby
Co-signatories of the letter
Church of England Election Letter

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 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?

Scanning electron micrograph of a mass of Yersinia pestis, apparently thriving inside Acanthamoeba castellanii.
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.

Another Ape-Man Makes a Fool of Creationists

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 6000 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 hominin, 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

An artist's impression of Homo floresiensis based on recent research. Dubbed a human "hobbit", the species of humanoid was about a metre tall and died out about 54,000 years ago.

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).

Neisseria gonorrhoeae infects the human endocervix by activating non-muscle myosin II-mediated epithelial exfoliation

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.
