By now, unless you live under a rock, you should have heard the news: New genetic studies indicate that Neanderthals and modern humans likely interbred: Among the findings, published in the May 7 issue of Science, is evidence that shortly after early modern humans migrated out of Africa, some of them interbred with Neanderthals, leaving bits of Neanderthal DNA sequences scattered through the genomes of present-day non-Africans. "We can now say that, in all probability, there was gene flow fro........ Read more »

Terrifying, painful, exhausting. When I have spoken with people who identify as having Morgellons disease, these are the words I hear. Most researchers and medical professionals consider Morgellons Disease (MD) to be synonymous with Delusory Parasitosis (DP), a false, unshakable belief that insects are living in or on your skin or inside your body. Yet, [...]... Read more »

Astute observers will have noticed that there's been something of a crisis in the financial world over the past couple of years. The EU's just coughed up €500 billion in the latest an effort to stem the panic... or, alternatively, to fend off the predators.
And that gets to the heart of the matter. Is the crisis just one of those things - part of a natural economic cycle that is beyond anyone's ability to predict or control? Or is it a result of moral or intellectual failures among those who........ Read more »

...and what can word-learning in dogs teach us about the evolution of language in humans?
What is involved in the learning of a single new word? Consider the word "tiger", being learned by a child with already a modest vocabulary, at least for animal words. First the child must make a new entry in the mental lexicon - that "tiger" is a word in the first place. He has to categorize it as a noun. It has to be categorized under "animal" (a supernym) and related to its hyponyms, like "Sumatran tige........ Read more »

Prohaska and Gailey (2010) refer to the practice of men who seek 'out women they [those men] perceive as fat or unattractive for sport or sexual gratification’ as 'hogging' (p.13). The big ticket issue, therefore, pivots between men who hate women absolutely and men who love other men for all the wrong reasons. In short, misogyny and homosociality.

Among the great American exports to the rest of the world, there are a bewildering variety of religious cults and sects. Not all have take root, but the most successful - groups like the Mormons, the Jehovah’s Witnesses, and the Seventh Day Adventists - now number in the millions.
Their success is mostly down to prosyletisation, in addition to any endogenous growth (due to fertility) that was the topic of the previous post.
So why are they so successful, and perhaps more importantly where ar........ Read more »

Israeli biologists Feder et al report on Selective breeding for dominant and submissive behavior in Sabra mice.Mice are social animals and like many species, they show dominance hierarchies.

For such a small area, the Five Points really has a great deal of history connected to it. Walking through present day Chinatown, I was really struck by how various elements of the Five Points have persisted through time, and have managed to impart some of the old character into the neighborhood. The streets bustle with throngs of Asian residents, reminiscent of the earlier immigrant settlers

In a paper entitled, “Leisure College, USA“ Philip Babcock and Mindy Marks have documented dramatic declines in study effort since 1961, from 24 down to 14 hours per week. This decline occurred at all different sorts of colleges and is not a result of students working for pay.
At the same time, colleges are handing out better grades. In other work, Babcock presents strongly suggestive evidence that the two phenomena are related. That is, lower grading standards lead to less st........ Read more »

The Moroccan Ministry of Culture has a press release (in French) about the cave site of Ifri n’Ammar, about 50km south (i.e., away from the coast) of Nador, indicating that the Moroccan-German team that has been working there for the past seven years has identified Aterian levels dating to about 175,000 BP. If these dates are correct, they push back the age for the earliest Aterian assemblages by some 65,000 year, since to date, the oldest Aterian levels had been identified at the Moroccan sit........
