Why Modern Forests Evolved

Plant Ecological Strategies Shift Across the Cretaceous–Paleogene Boundary | PLOS Biology, September 16, 2014

The thing about science is that it all fits together to form a large picture, so it's always rewarding when one little piece of evidence is found which confirms another piece, or, if not exactly confirms it, certainly goes a long way towards supporting it. Take for example, the evidence from the fossil record that the

Something Is Bugging Creationism.

Evolution doesn't read any rules and feels no obligation to conform to any norms, so we should expect the unexpected. If we didn't get the occasional surprise it would start to look just a little too predictable. If things were as the creationist loons and frauds like to claim, we would expect an intelligent, perfect designer, to at least show bit of consistency.

After all what perfection is there in randomness and how does no pattern at all look like design according to a plan? No doubt though the frauds will fall back on the traditional woo-woo excuse of ineffability and mystery and beyond human comprehension which renders their crackpot notion redundant as a

Scotland And The United Kingdom

This Thursday's Scottish referendum on independence from the rest of the United Kingdom is a pivotal moment, not only in the history of Scotland but in the history of the United Kingdom. It's worth passing briefly over the history of Scotland and its considerable part in the history of the British Isles.

A great deal is made by the pro-independence movement of Scotland's 'distinct identity' with very little analysis of the truth of the claim. For example, industrial Glasgow, Aberdeen or Dundee probably have far more in common culturally with Newcastle, Liverpool, Sheffield, Manchester, Birmingham or Southampton than they do with Wester Ross,

Neanderthal Extermination Mapped in Detail.


Neanderthal demise traced in unprecedented detail - life - 20 August 2014 - New Scientist

The story of the demise of the Neanderthals and their replacement by modern Homo sapiens in Europe became a little more clear a couple of weeks ago but the clarifying picture is beginning to look bad for us moderns humans.

It's beginning to look like we were one of the first invasive species; one which was not just a disinterested observer of the demise of our cousin

Atheism Increasing In Line With Intelligence

Brain drain: Are we evolving stupidity? - life - 20 August 2014 - New Scientist

An article by Bob Holmes in New Scientist this week reports that there appears to be a slight reversal in recent years of a trend in IQ scores which had been almost invariably upwards since records began to be collected in the 1950s.

The primary data comes from a standard IQ test given to 18 year-old Danish males as part of their conscription into military service. With the exception of a brief downward trend in the late 1970s, the reported IQ scores increased sharply until about 1995, then plateaued and now appear to have gone into reverse.

This sharply upward trend has been seen in every country where living standards and nutrition have improved, as they did in most of post-war Europe from the 1950s onwards. This change is known as the

Creationism, Amber And Mitey Ants.

Mite and ant locked together in amber - Nature | News.

You don't have to go scrabbling around in gravel beds, old quarries or Jurassic Coast beaches like Lyme Regis to find fossils. You can find them in old museums or they can simply arrive in the post as this one did. It was sent to Jason Dunlop, an arachnologist at the Leibniz Institute for Evolution and Biodiversity Science in Berlin, Germany, by a serious collector of fossil spiders who buys quantities of amber and searches through them.

This Baltic Amber is 44-49 million years old (fairly young by geological standards) and contains a rare example of of a fossilised mite and the first of this particular species (Myrmozercon sp.). Significantly, this is also the earliest example of a mite being found attached to its host, in this case the ant Ctenobethylus goepperti, a social

How Transitional Fish May Have Learned To Walk

Polypterus senegalus
How fish can learn to walk : Nature News & Comment

A fascinating piece of research published a few days ago shed some light on how transitional fish/amphibians may have learned to walk on land as they moved from an aquatic to a terrestrial existence.

The researchers from the University of Ottawa, Canada, led by Emily Standen, took juvenile bichir (Polypterus senegalus) - a freshwater fish from Africa which has a primitive lung as well as gills and so can live on land - and raised them on land for eight months. The control group was raised in water as normal.

The land-raised bichir showed not only a noticeably more sophisticated style of walking but there were

Abuse-Aware Cardinal Brady Retires On Full Pension

Pope accepts resignation of head of scandal-plagued Irish church - Reuters.

In a demonstration of his determination to clean up the Catholic Church and show the world his remorse for the decades of institutional child abuse and systematic cover-up by senior clerics, Pope Francis has allowed Cardinal Sean Brady, "Primate of All Ireland", to retire quietly at the normal age of 75 when Cardinals are expected to retire, or at least to formally offer their resignation, anyway.

To save the poor man embarrassment by being sacked, he had been effectively on gardening leave for the past year while his duties as Bishop of Armagh had been undertaken by the specially appointed "coadjutor", Monsignor Eamonn Martin, who will now formally take up Brady's old job.

Cardinal Brady became notorious in 2012 when a BBC documentary revealed that he had known about, but had failed to warn parents, of the child-abusing priest, Father Brendan Smyth, who was sentenced to 12 years in prison after pleading guilty to 75 charges of indecent and sexual abuse of boys and girls over a period of more than 30 years. Brady always claimed the documentary was misleading, but apologised for his part in the scandal.

Malignant Melanoma - Another Gift From The Intelligent Designer?

We've just spent a glorious week in the South of France on the Côte d'Azur where the sun beats down from an azure sky on the more or less sun-tanned or sun-burned bodies, prostrate on the beaches wearing next to nothing and exposing skin normally hidden where the sun don't shine - and most of them European from further north.

You see, pale skin is generally recognised as an adaptive feature in Euro-Asian peoples because darker skin, which evolved in Africa, filtered out too much sun to make enough vitamin D - which is made in the skin in response to sunlight and we don't normally get enough in our diets.

Wandering Stones - A Lesson for Creationists

'Wandering stones' of Death Valley explained : Nature News & Comment

The 'mystery' of the 'Wandering Stones' of Death Valley, California has been definitively solved by, surprise! surprise!, science - and there is a subtle but crushing lesson for creationists and other magical thinkers in the mystery. Actually, the stones aren't in Death Valley but in Racetrack Playa in a valley in nearby mountains. The mystery was how they move across the flat dried-up lakebed, apparently without any assistance.

The answer had been proposed earlier but observation - the basis of all good science - has finally proved that thin ice sheets form when the normally dry ancient lakebed floods to a depth of a few centimeters and then freezes

Yawning Wolves Show Empathy

Yawning Spreads Like a Plague in Wolves | Science | Smithsonian

More evidence emerged this week that the ability to empathise with members of the same species, and even, in some cases, across species, is not unique to humans but is also present in non-humans. A paper published today in PLOS One by a team of researchers from Tokyo University showed that yawning is contagious in wolves (Canis lupus).

Yawning is generally regarded as an empathetic response when it is copied. It is very difficult for

How Creationists Lie To Us - Age Of The Sun

Spot the liar.

Dr Paul D. Ackerman, Creationist:

Around the turn of the century, the famous scientist Lord Kelvin created difficulties for evolutionists by presenting a number of powerful arguments against the long ages needed by their theory. In a widely heralded debate with the famous evolutionist Thomas Huxley, Lord Kelvin tore the evolutionists' position to shreds with simple and straightforward physical arguments that the earth and solar system were not old enough for life to have arisen by Darwin's proposed evolutionary process. Among Lord Kelvin's arguments on the age issue was the time factor for the sun's survival based upon Helmholtz's accepted model of gravitational collapse. Lord Kelvin had the theory of evolution on the ropes and had seemingly dealt the knockout blow.

Pests and Creationism

The German Cockroach, Blatella germanica.

Meet the lodgers: Wildlife in the great indoors - life - 24 August 2014 - New Scientist

The german cockroach, Blatella germanica, lives almost everywhere that humans live. It lives in our homes, our hospitals and hotels, in our shops and factories and sewers and offices. In fact it lives in practically any buildings built by humans and especially heated ones with food in. But it is completely unknown in the wild and quickly dies if stranded outdoors. (It is probably all too obvious already what question I'll be asking creationists at the end of this blog.)

Quite when and where it took up with humans and evolved its complete dependence on us is unknown but it is believed to have been somewhere in Africa, probably before we were modern humans. Its ancestors might well have lived in caves like several other species of cockroach.

B. germanica has shown itself to be capable of rapidly evolving. In the 1980's the control method of choice was to use sugars laced with insecticides then, in the 1990s, this stopped being effective. Cockroaches had not, as might seem probable, evolved a resistance to, or tolerance of, insecticides; they had evolved

Vatican Still Avoiding Responsibility For Abusive Priests

Top Vatican figure in row over child abuse comments.

A senior Vatican Official astounded the Australian victims of peodophile priests by telling the Australian Royal Commission into Institutional Responses to Child Sexual Abuse that the Catholic Church had no more legal responsibility for the actions of its priests than a truck firm has for the actions of its truck drivers.

Cardinal Pell, a former archbishop of both Melbourne and Sydney, was personally appointed to a top job in the Vatican, as head of the finance ministry, by Pope Francis

Unintelligently Designed Hummingbirds

Evolution of sweet taste perception in hummingbirds by transformation of the ancestral umami receptor

Hummingbirds are unique amongst birds in living off nectar and being able to detect sweetness. Typically, hummingbirds only feed from flowers with nectar containing more than 10% sugars. The way this evolved illustrates a couple of basic principle of diversification by evolution and the lack of a directing intelligence or plan behind it. Something else for creationists to misrepresent, lie about or ignore but never, under any circumstances, face up to.

Chimp Eyes Show Evolution of Ethics

Chimps show empathy by mimicking pupil size - life - 22 August 2014 - New Scientist

More evidence guaranteed to trigger the avoidance reflex in creationists was published in PLOS ONE this week. It shows two things which any creation pseudo-scientist worthy of the name will need to misrepresent, lie about or ignore altogether. It shows evidence that humans and chimpanzees share a common ancestor and that chimpanzees too have empathetic ability - the basis of a ethics and the ability to make ethical decisions. In other words, chimpanzees have morality and they,

More Manny Insanity

As regular readers will know, some two years ago I posted a challenge to a Twitter user then using the account name @Sacerdotus who had been posing as a Catholic priest in training and claiming multiple university degrees in philosophy, physics, theology, psychology - in fact almost anything you cared to mention. He had been claiming to have irrefutable, scientific proof that the Christian god existed and that no other go did, and challenging people to debate him.

After one hilarious day during which, in the small hours of the morning in the UK, he posted dozens of challenges to me, one every few seconds and then declared victory claiming I had ignored him, I decided to call his bluff and challenged him to a formal, neutral and independently refereed debate,

Pygmies - Another Big Problem for Creationists

Baka pygmies, West Africa
African pygmies evolved their short stature twice - health - 18 August 2014 - New Scientist

A paper published in PNAS last month is interesting for what it tells us of human evolution and of evolution in general, and it raises a major question for creationist loons to carefully avoid.

Significance

Tropical rainforest hunter-gatherer populations worldwide share the pygmy phenotype, or small human body size. The evolutionary history of this phenotype is largely unknown. Here we studied DNA from the Batwa, a rainforest hunter-gatherer population from east central Africa, to identify regions of the Batwa genome that underlie the pygmy phenotype. We then performed population genomic analyses to study the evolution of these regions, including comparisons with the Baka, a west central African rainforest hunter-gatherer population. We conclude that the pygmy phenotype likely arose due to positive natural selection and that it arose possibly

Scientists At War!

Scientists at war over claim that Flores hobbit man is modern human with Down's syndrome | Science | The Observer

This slightly alarming headline from the Observer leads neatly into a comparison between how scientists wage 'war' what's going on in the Middle East at the moment where theists are waging war - and happily killing one another and innocent civilians including women, children and other non-combatants as a matter of routine.

Another contrast of course is that, whereas the scientists' 'war' will undoubtedly end in agreement with almost

Abiogenesis - The Day of Reckoning For Creationists is Nigh

Meet your maker: Homing in on the ancestor of all life - life - 12 August 2014 - New Scientist

Creationist pseudo-scientists have a problem, and not the obvious one of more and more people seeing through their deceptions, working out why they are necessary and realising a rational, scientific explanation is preferable to a magical one which requires lies and misinformation to promote it. The problem they have is, like the problem of the virtual certainty that at some point in the near future, scientists will find evidence of life on another planet, probably in another planetary system, the problem of one of their fundamental arguments being shown to be without any foundation.

I'm talking about the fact that science is getting closer

Religious Intolerance

Someone posted a question in our Why Atheism? Facebook group the other day asking which religion was the worst, especially in the context of the Middle East where the three Abrahamic religions are currently slugging it out for control of Iraq, Syria and Palestine, and in Africa where Muslims and Christians are also fighting and killing for their religions.

Looking at the history of Europe and the Middle East particularly, and later the history of European colonialism, it's probably true to say that, until 1948 the one Abrahamic religion that had generally been on the receiving end of persecution and atrocity and yet had no history of retaliation or counter atrocity was Judaism.

In fact, the contribution of Jews to European and Middle Eastern philosophy, art, politics, science, medicine,
