Human Evolution - Completing the Picture

To me, watching a science grow and develop is what makes it more like an adventure than a dull, academic subject. Discoveries are made and fed into the mix; ideas and opinions are contributed by people who are experts in the field; old ideas are revised, reviewed and discarded if necessary and eventually a new consensus emerges which is, in the long run, a little closer to the truth. All the while the picture grows in clarity, sometime becoming more complex that we thought and sometimes simpler.

How unlike religion where the entire effort is devoted to excusing yet again that which is nothing more than evidence-free dogma, finding new and ever-more creative workarounds for the fact of no evidence, and inventing new ways to bamboozle a diminishing following into believing that, despite the overwhelming evidence to the contrary, and despite the enormous gains of science and its contribution to human welfare since the enlightenment, their Bronze-Age belief in magic is the best explanation of reality.

A couple interesting articles in this week's New Scientist illustrate how our knowledge of human evolution keeps being added to and our understanding of is revised and refined accordingly.

Silly Bible - Lot of Nonsense

Albrecht Dürer Lot Fleeing with his Daughters from Sodom (1498)

The biblical story of Lot is another strange tale with no obvious reason for being in the Bible, at least so far as morality tales go. In fact, it shows the god of the Hebrews in a very poor light, overly obsessed with what humans do with their genitalia but having a low regard for women and no problem at all with incest. It also portrays it as far from omniscient, unsure of what justice means and easily persuaded by a mere human but then capriciously changing its mind and killing innocent people anyway simply for being there at the time.

We also see how the person writing it had difficulty holding a thought across more than a couple of paragraphs.

I have already written about the nonsensical account of God telling Abram that he was going to destroy the cities of Sodom and Gomorrah and Abram bargaining God down from fifty to ten as the number of righteous people to be found in the cities to prevent him killing everyone, innocent or guilty.

There doesn't seem to have been any such attempt to find ten righteous men though and God sets about killing everyone anyway. To accomplish this he sends two angels to the city and they end up at Lot's house, where a mob comprising all the men of the city gather outside demanding to be allowed in to bugger the angels.

More Bible Blunders

Some time ago I wrote about Thomas Paine's debunking of the notion that the Pentateuch was written by Moses, as though supposedly writing about his own death and burial in a secret place wasn't enough. Thomas Paine, in The Age of Reason, written in 1794 showed that the Bible refuted that argument itself. First we are told in Genesis that:

And when Abram heard that his brother was taken captive, he armed his trained servants, born in his own house, three hundred and eighteen, and pursued them unto Dan.

Genesis 14:14

Then later on we discover that it wasn't actually called 'Dan' until much later; before then it was called 'Laish'.

Parasites and Creationists

I've commented before on how parasites are a problem for creationists and, apart from their understandable shyness at discussing parasitism, this probably explains why creationist loons who misrepresent science and misinform scientifically illiterate people for a living never seem to discuss parasites or explain how they fit into an intelligent design model, especially one in which the supposed intelligent designer is omnibenevolent and created everything just for humans.

For example, the leading Discovery Institute (aka Liars For Power and Money, Inc.) propagandist for ID, Michael Behe, avoids completely any reference to the fact that his 'intelligently designed' E. coli flagellum appears to have only one purpose - helping E. coli make us sick.

With their evident discomfort in mind then, it gives me great pleasure to invite creationists to comment on an article and two papers published recently in Science concerning how infection by a parasitic worm (helminth) can appear to aid other parasites by helping them overcome the body's natural immune responses. In particular, I would like them to explain how this phenomenon is better explained by their intelligent-design-by-an-omnibenevolent-designer-who-did-it-all-for-humans model than it is by Darwinian evolution by Natural Selection.

The Incredible Shrinking Dinosaurs

Dinosaurs shrank for 50 million years to become birds - life - 31 July 2014 - New Scientist

I was surprised and more than a little disappointed to to see the angle taken in the above article. It looks almost designed to supply a handy quote for quote-mining creationist pseudo-scientists to mislead their credulous victims with.

"No other dinosaur group has undergone such a long and extended period of miniaturisation," says Mike Lee of the South Australian Museum in Adelaide. "Statistically this trend was far stronger than by chance, analogous to flipping a coin a dozen times and getting all heads."

[...]

The analysis reveals that the ancestors of birds shrank without interruption. "What was impressive was the consistency of the size change along the dinosaur-to-bird transition, with every descendant smaller than its ancestor," says Lee.

It's not till we get to the final sentence in that last paragraph that we discover there is a simple and obvious answer and one moreover which illustrates how Natural Selection makes evolution non-random.

Origins Of The Exodus Myth

With so many to choose from, it's difficult to decide which of the various folk tales, invented 'histories' and origin myths that have found themselves bound up in the same book and presented as the inerrant word of an omnipotent god is the silliest, but one of them has to be the tale of Hebrew enslavement in Egypt and subsequent escape.

It was obviously written by someone who knew little or nothing of the geography or politics of the time and place the tale was set, so we have the idiotic notion of the 'Israelites' escaping from Egypt by crossing the Red Sea to Sinai - which was also in Egypt. That's like 'escaping' from the USA by crossing the Hudson River from New Jersey to Manhattan or escaping from the UK by crossing the Bristol channel from England to Wales. The author also has the 'slaves' building the Egyptian city of Raamses - which wasn't started until some 120 after the traditional date of the Exodus.

Killer Sperms Reinforce the Species Barrier

Killer sperm ravages internal organs of luckless worms - life - 30 July 2014 - New Scientist

I've mentioned before how, as two diverging nascent species each evolve specialisation, hybrids will often be at a disadvantage being good an neither of their parent's specialities. As isolated and diverged populations of finches came back together, at the end of the last Ice Age for example, one might have evolved a long thin beak for eating small seeds and the other a short stout beak for eating large hard seeds. A hybrid with a long stout beak or a short thin one would find feeding difficult so it would be in the interests of both sets of genes to set up barriers to interbreeding.

The very fact that they are diverging accelerates the process of speciation, not as an end in itself but to protect the advantageous genes from being wasted on hybrids which have a lower probability of passing them on (see Why Species?, Creationist's Macro-Evolution Lie and More Mimetic Evolution).

We now have a rather surprising, even shocking example of one such barrier in closely related nematode worms.

More Evolved Mimicry

This is my last blog for a while on the fascinating topic of mimicry in animals and plants. Previously I wrote about Batesian and Müllerian mimicry in Copycat Evolution and More Mimetic Evolution where a harmless species comes to resemble a harmful one and so gains protection from a predator which has learned to avoid the harmful one (Batesian), or two harmful species come to resemble one another and so gain from the evolutionary 'spade-work' of the other (Müllerian).

Now I'm going to look at another form of mimicry where (usually) a plant deceives another species into thinking it's something else, not to repel or avoid it, but to attract it. Almost invariably this improves pollen or spore distribution so it's not hard to understand how any improvement in this system gave the plant an advantage and so natural selection favoured it.

Murmuring Starlings Do It Naturally.

Decisions ripple through flocks of birds like a wave - physics-math - 27 July 2014 - New Scientist

One of the most spectacular sites in nature in Britain is a winter 'murmuration' of starlings, and I'm fortunate enough to live just a short drive from the open stretch of moorland north of Oxford known as the Otmoor, now a wonderful RSPB-owned nature reserve and important inland wetland site, where this spectacle can be seen most winter evenings at sunset in suitable weather.

Watch these videos first, then I'll discuss them. The first was filmed over Otmoor, the second at Gretna in Scotland.

More Mimetic Evolution

Having blogged a couple of days ago about the role of mimicry in evolution I decided to look more closely at the subject, especially the widespread mimicry found in butterflies. The results are fascinating.

But before I get on to that I'll just deal quickly with another aspect to evolution - speciation - following on from something I mentioned in the same blog. I pointed out how mimicry involved a two species both of which are prey to the same predator and where at least one of them is toxic or harmful to the predator.

I mentioned that the selection pressure for one species to become more and more like the harmful one depends on the presence of the predator in the local environment but the species range may well include areas with different predators, different comimics or indeed the absence of one or both. In this case, and in that part of the range there may be no selection pressure and no particular advantage in adopting the colour pattern of the toxic or harmful species, and there may even be a disadvantage because a different predator may not have any aversion to the mimicked colour.

Recent Evolution - That Old Chestnut

Horse chestnut leaves infested with Cameraria ohridella lavae.

If you live in Southern England, for an example of very recent evolution you probably only need walk to your nearest horse chestnut tree. I took this photograph near Sunningwell, Oxfordshire earlier on Saturday when we went out for a last distant look at Didcot Power Station, which is probably England's best-loved 'eyesore' but which is due to disappear in a cloud of dust in a few hours time. The chances are that by now your nearest horse chestnut tree will be becoming infested with the leaf-miner caterpillars of a moth which was unknown before 1985 when the first outbreak was recorded in Macedonia, Greece.

Since then, Cameraria ohridella has spread at an average of 60 Km per year across western Europe reaching England in 2002, where it is now widespread, causing the leaves of horse chestnut trees (Aesculus hippocastanum) to turn brown, wither and fall off by late summer. Devastating though this attack appears, the general health of the trees seems not to be unduly affected since they come back into leaf and grown normally the following spring.

Although this moth was a newly-discovered species in 1985, specimens of it were accidentally collected and pressed in botanical specimens as early as 1879 only to be rediscovered when a team of researchers carried out a systematic search of specimens stored in herbaria.

Abstract
Determining the native geographic range or origin of alien invasive species is crucial to developing invasive species management strategies.

Copycat Evolution

Which ones would you pick up?

A friend asked me the other day to explain how mimicry can play a role in evolution. This is my attempt to do so.

There are in fact two main types of mimicry recognised by biologists, although the distinction is quite technical and is blurred anyway. For all practical purposes, they can both be regarded as forms of the same thing. They are known to biology as:

• Batesian mimicry. Named after the English naturalist Henry Walter Bates. This is where a harmless species evolves to resemble a harmful species if it and the harmful species share a common predator.
• Müllerian mimicry. Named after the German biologist Fritz Müller. This is where two harmful species evolve to resemble one another if they both share a common predator.

"We'll find a new earth within 20 years" | Around the World with Ken Ham

Signs that Ken Ham may be beginning to panic at the thought that science could soon find evidence of life on another planet emerged recently with this desperate attempt to harness his fundamentalist audience in a bid to stop NASA looking for it, dismissing it as a waste of money which is bound to fail. His panic can be gauged from the horrible muddle he gets into with his argument where he inadvertently 'proves' that there isn't non-human life on Earth either.

He also showed his traditional propensity for making things up, even about the Bible, and relying on his ignorant audience not checking.

The Sacred Conclusion

Most theists will deny that they do it but it's usually easy to demonstrate that religious beliefs are not based an objective assessment of the evidence but on a received conclusion which is then protected and reinforced by highly selective cherry-picking of the evidence which is often heavily weighted whilst contradictory evidence is minimised, ignored or dismissed on spurious grounds.

'Evidence' can even include assumed evidence such as that 'list of eyewitnesses of the life of Jesus', 'all those fulfilled prophecies in the Bible which have been independently verified', or, in the case in point, 'all the historical names, places and events' mentioned in the Bible.

Nothing wrong with these as examples of evidence, of course, apart from just one thing - they are all false. There are no authenticated eyewitness of the life of Jesus; there are no fulfilled prophecies in the Bible which can be independently verified and there are no historical names, places or events in the Bible which give it an authenticity as a holy book.

It's been another bad week for the Intelligent Design industry. No wonder their secretive five year 'Wedge Strategy' is now well into it's sixteenth year, during which the number of non-believers in the USA has gone up from about 4% to about 20%, conservative Christianity has become the preserve of the white right fringe and court after court has thrown out their attempts to subvert the Constitution and smuggle fundamentalist Christian extremism into the US public school system disguised as science.

Clearing Up the Unintelligent Designer's Mistakes

I'm homing in on the genetic essence of life - opinion - 14 July 2014 - New Scientist

In an interview published in New Scientist a few days ago, 1978 Nobel Laureate and synthetic biologist Hamilton O. Smith said:

The other thing we want to know is... how much can we rearrange the genes? Evolution has sloppily put them together. A lot of the cell's processes are scattered around. We're putting them together into one neat form.

He was explaining how his synthetic and bioengineering group at the J. Craig Venter Institute in La Jolla, California, USA is using the genome of a bacterium Mycoplasma mycoides to investigate the minimum number of genes needed to function as a viable, living organism.

Their greatest challenge is to work out exactly what DNA is junk, i.e., which has been included over billions of years but which now doesn't serve any purpose. Hamilton Smith estimates that it only needs 400-450 genes to make an organism viable. The other task is to rearrange these genes more efficiently instead of being scattered around the genome in the haphazard and 'sloppy' way they are in M. mycoides.

Altruism and Tits

Long-tailed Tit (Aegithalos caudatus)

Browsing through my Royal Society for the Protection of Birds (RSPB) magazine, Nature's Home, just now I came across a reader's letter asking about something he had seen with nesting long-tailed tits recently. He had noticed that several adults were helping to feed the young in addition to the parents and wondered if this was normal.

It is. It is a lovely example of altruism in one of my favourite birds.

The so-called long-tailed tit - it's actually closer to the warbler family than the tits - is one of the UK's smallest bird. Were it not for it's long tail it would actually equal the size of our smallest two, the

A Message From 270 Million Years Ago

Amphibians' swim stroke has lasted 270 million years - life - 15 July 2014 - New Scientist

Fascinating pictures of 270 million year-old fossils tracks from the Alps were published today, sadly most of them behind a paywall. They show the tracks laid down, probably by a salamander, as it paddled across a shelving patch of mud from shallow into deeper water and eventually taking to swimming. This is the first recorded instance of the transition from walking to swimming.

Abstract
Exceptionally preserved Early Permian tetrapod trackways from the Orobic Basin (Central–Western Southern Alps) offer a unique opportunity to investigate in detail locomotion in fossil vertebrates that lived on continental European landmasses. Herein are reported the results of a study on several tetrapod trackways that display a large variety of behavioral, gait and substrate related extramorphologies. They clearly document the transition from terrestrial–underwater walking to swimming and are assigned to the compound ichnotaxon Batrachichnus C Lunichnium. The use of the “C” symbol is here introduced for the first time as nomenclatural indication of a Compound trace. Producers were probably small-sized temnospondyl

Here's a fascinating piece of research from Sweden which is enough to give any self-respecting creationist pseudo-scientists a split personality.

Incidentally, thanks to Helmer von Helvete, a friend from Google+, for bringing this to my attention.

Catholic Church "Untrustworthy"

The Catholic Church in Germany is witnessing an astonishing collapse in public trust and is haemorrhaging members at an unprecedented rate.

According to a Forsa poll recently 65% of Germans said they found the Catholic Church untrustworthy.

This trend has been linked to the 'bling bishop' scandal in which Catholic Bishop Franz-Peter Tebartz-van Elst was found to have spent millions of euros of church money on his own private house. He later 'resigned'. Once again ordinary Catholics had to endure the embarrassment of yet another Catholic cleric abusing the power and trust his position gave him.

In Germany, a tax is levied on church members by the

A detailed study led by Alfonso Valencia, Vice-Director of Basic Research at the Centro Nacional de Investigaciones Oncologicas (National Cancer Research Centre - CNIO) in Spain, and published in the journal Human Molecular Genetic found that about 90 percent of protein-coding genes found in humans are common to the earliest metazoans (multicellular organisms), that 99 percent of them pre-dated the emergence of the primates 50 million years ago.

Uncontacted tribe in Brazil ends its isolation | Science/AAAS | News

News that a previously isolated Amazonian tribe has made voluntary contact with a group of Brazilian government scientists from (FUNAI) marks a departure from the Brazilian Department of Indian Affairs' 'no contact' policy but was deemed necessary in this case because there was a serious threat to the welfare of the tribe from other tribes in the ares, following reports of raids on crops and theft of tools.

The reason for the 'no contact' policy is because of the very real threat to isolated people from the viruses we often take for granted such as influenza, measles and mumps. Between 1983 and 1985 some 60% of the

Consciously Evicting God From Another Gap

Consciousness on-off switch discovered deep in brain - life - 02 July 2014 - New Scientist

One of the favourite arguments used by religious apologists is that somehow materialism can't explain conscious thought and that a 'random' [sic] process like evolution could only ever give rise to random thoughts and not rational arguments.

Of course, this argument is never revised to accommodate developments in science and in our understanding of neurophysiology and the microscopic structure of neurons, so it is identical in form whether used by C.S.Lewis, William Lane Craig or Ken Ham even though our understanding of the science has been transformed immeasurably in the intervening half century.

But then we need to remember that religious apologists are not seeking to make converts but to keep believers believing and thus to ensure their income stream is maintained and the arrogant claims they make to

Green River Exposes Layers of Creationist Lies

Green River Formation varves

One of my favourite creationist pseudo-scientists must be the psychologist with no qualifications in science or record of research in the subject, Dr. Paul D. Ackerman, who supplements his income from teaching psychology as an assistant professor at a minor university by writing bad science books and articles for creationists who also seem to have little knowledge or understanding of science. He ranks as one of my favourites becaiue he is so bad at it.

He is the notorious author of what must rank as one of the worst 'science' books for creationists ever published (it now has to be given away by the Institute for Creation Research) called It's A Young World After All: Exciting Evidence For Recent Creation. I've already dealt comprehensively with this book in a series of blogs so I won't dwell any more on it here, save to quote Dr Ackerman on what is one of the few nearly true things he said in his book:

Still Not Yeti!

Genetic analysis of hair samples attributed to yeti, bigfoot and other anomalous primates

Last October I reported on a tentative claim by geneticist Bryan Sykes of the Oxford-Lausanne Collateral Hominid Project that he might have solved the Yeti question, only the Yeti is a descendant of a Paleolithic bear known from a single jawbone from northern Norway. This bear is believed to be ancestral to both the polar bear and the brown bear. His claim was based on a comparison of mitochondrial DNA (mtDNA) from samples of hair claimed to have come from Yetis with those of known species held on the GenBank database, an international database of genetic information.

mtDNA is inherited in mammals from the female line only and, because it doesn't recombine during sexual reproduction, tends to be stable over time, mutating at a more or less constant rate. It thus makes an excellent means of tracing female line populations and evolutionary relationships. The biological significance of this find was not so much that it might have solved the Yeti question but that it might have revealed a living population of this Ice-Age bear in the Himalayas, where it might have taken refuge as the ice retreated.

Now Bryan Sykes has reported on a much more extensive investigation of mtDNA from hair samples of 'Yeti', 'Bigfoot', and

Ever since Richard Dawkins coined the term, 'meme' in The Selfish Gene we have known that cultures, like genomes, are passed on through the generations by replicators which can gradually change over time and which can be subject to selection pressures, just like genes and combinations of genes. The difference is that memes are inherited after birth and so, unlike genes, we can change them and chose which to accept and which to reject. We can also chose which to pass on and which to allow to be consigned to history.

You can say one thing about The Intelligent Designer - it doesn't let liberal sentimentality, compassion or morality get in the way of a good idea. In fact, it's almost exactly like The Intelligent Designer doesn't have any emotions or compassion, nor any idea of right and wrong.

I'll take that back. There is no 'almost' about it. It's exactly like The Intelligent Designer doesn't have any emotions, compassion or sense of right and wrong. It's exactly like The Intelligent Designer doesn't have any intelligent plan or any real purpose for its designs either.

Fighting Back Against Evolution

Antibiotic resistance focus of UK’s Longitude Prize : Nature News Blog

Great news that, by popular vote, the £10 million ($17 million) Longitude Prize will be awarded to the group which comes up with "a cost-effective, accurate, rapid, and easy-to-use test for bacterial infections" within the next five years. The intention is to help target antibiotic use so reducing the rate at which bacteria are evolving resistance.

This comes close behind a stark WHO report which stated:

Antimicrobial resistance (AMR) within a wide range of infectious agents is a growing public health threat of broad concern to countries and multiple sectors. Increasingly, governments around the world are beginning to pay attention to a problem so serious that it threatens the achievements of modern medicine. A post-antibiotic era—in which common infections and minor injuries can kill—far from being an apocalyptic fantasy, is instead a very real possibility for the 21st century.

Parasite Problem for Creationists

Stone Age worm egg hints at origins of modern scourge - health - 20 June 2014 - New Scientist

News that the earliest known evidence of the parasitic flatworm which causes schistosomiasis in human has been found, reminds me how rarely we see creationist pseudo-scientists discussing parasites, least of all parasites on humans. Maybe they are just sensitive to the subject for understandable reasons given their generally parasitic lifestyle but that would require a social conscience. It's much more likely that it's impossible to fit them into a biblical model where a magic, benevolent god created everything for humans because it loves us.

Parasites, by definition, take from their hosts but give little or nothing in return. They also often make their hosts sick in the process.

Magnetic Reversal For Creationism

What would it take to convince a creationist that Earth is not just a few thousand years old?

To be frank, the answer to that is probably nothing - nothing on Earth would convince them because nothing on Earth convinced them it was just a few thousand years old in the first place. They were told that was the right thing to believe and that to be immune to reason and blind to contradictory evidence is something to be admired. The conclusion is sacred so facts must be ignored.

But imagine if there was some way Earth could have recorded its age in a way that is irrefutable, like a prisoner in a cell making a mark on the wall every day, and suppose this mark was not just marked on stone or even carved in stone but embedded forever in the structure of the stone itself, so no-one could have forged it or changed it and the only way to get rid of it was to destroy the stone itself.

Silly Bible - The Fishy Tale Of Jonah

It's sometimes fun to read through the Bible and work out which of the tales in it is the least plausible, the most pointless, the least well thought out, etc.

A strong contender for all three of these is the story of Jonah. It must rate alongside the Noah's Ark and the Tower of Babel stories as the silliest and, given that the Tower of Babel tale actually tries to explain why different people speak different languages so has some point to it, like Noah's Ark, the tale of Jonah doesn't actually offer anything by way explanation for anything we can observe.

Nor is it any more plausible because the scientific evidence shows that it couldn't have happened, although, to be fair to whomsoever made up the Jonah myth, at
