Digesting Milk in Ethiopia: A Case of Multiple Genetic Adaptations – “A team of geneticists from UCL, University of Addis Ababa and Roskilde University have shown that five different alleles are found in the Ethiopian population that cause adult lactase production, one of which is newly confirmed.” – h/t andrew badenoch!
Friendship and Natural Selection – “More than any other species, humans form social ties to individuals who are neither kin nor mates, and these ties tend to be with similar people. Here, we show that this similarity extends to genotypes. Across the whole genome, friends’ genotypes at the SNP level tend to be positively correlated (homophilic); however, certain genotypes are negatively correlated (heterophilic). A focused gene set analysis suggests that some of the overall correlation can be explained by specific systems; for example, an olfactory gene set is homophilic and an immune system gene set is heterophilic.” – via charles!
Bone dates ‘earliest northerner’, say archaeologists in Liverpool – “Liverpool John Moores University and the University of Nottingham analysed a leg bone found in Cumbria and found it to be more than 10,000 years old.” – [winter is coming….]
Convergent evolution seen in hundreds of genes – “Bats and dolphins may have developed echolocation via similar mutations.”
Darkness in Anthropology: A Conversation with Napoleon Chagnon – “Probably the single most anthropologically unacceptable thing I did was to take ‘biology’ seriously…. I began using commonly known ways to ‘measure’ relatedness between organisms — Sewall Wright’s coefficient of inbreeding and its extended concept, the coefficient of relatedness. This was very unusual in cultural anthropology. In short, I was discussing Yanomamö kinship with *the biological meaning* of kinship in mind — at a time when the vast majority of cultural anthropologists assumed that ‘kinship’ and ‘the biological meaning of Yanomamö kinship’ were, at best, only vaguely similar and any allusion to this was generally ‘suspect.’ But since ‘kinship’ was traditionally a central focus of anthropological theory, I began developing ways to show precisely, using my meticulous genealogies on the Yanomamö, that people took sides in fights according to how closely *genetically* they were related to each other and fought against people they were *less related to genetically*. Many of the most prominent anthropologists held the extreme view that ‘kinship’ among humans had *nothing* to do with the biological meaning of kinship as is assumed in the fields of biology, genetics, or animal husbandry. A common claim was something to the effect that ‘whatever kinship among humans was about, it was NOT about biology.'” – h/t g-nice!
Penn Biologists Show That Generosity Leads to Evolutionary Success – stewart and plotkin “examined the outcome of the Prisoner’s Dilemma as played repeatedly by a large, evolving population of players. While other researchers have previously suggested that cooperative strategies can be successful in such a scenario, Stewart and Plotkin offer mathematical proof that the *only* strategies that succeed in the long term are generous ones.”

On the Relevance of Science to Morality – “[I]ssues of morality can’t be answered by scientific experiments because there are no such entities as issues of morality…. Moral emotions are part of the behavioral repertoire of several species of animals, including human beings.” – helian makes me smile. (^_^)
The Clannish World of Organized Crime – “[T]he way clannishness and OC go hand in hand like described above can’t be a coincidence. Rather, it makes perfect sense given the very definitions of these concepts. Clannishness is taking care of yourself and your group, often with violence, at the expense of other people and society. OC can be described in the exact same way.” – oh, yes. – from staffan.
Obesity in Germany: The fault-line divides the nation again – from agnostic.
Why are we the naked ape? – “Loss of body hair was a long-term evolutionary trend in ancestral hominids and even ancestral primates, being perhaps a response to a greater need for social signaling. In ancestral humans, the selection pressure seems to have gone through three stages, initially targeting infants and only later women and then men.” – from peter frost.
Are girls too normal? Sex differences in intelligence – “Girls are more normal, boys are more extreme, so there are more boys at extremes, and the more extreme the extremes, the more boys.” – from dr. james thompson. – [are girls too normal? – i’m not! (~_^) ]

The New Science of Mind – “Any discussion of the biological basis of psychiatric disorders must include genetics. And, indeed, we are beginning to fit new pieces into the puzzle of how genetic mutations influence brain development.”
Ability to delay gratification may be linked to social trust – “A person’s ability to delay gratification — forgoing a smaller reward now for a larger reward in the future — may depend on how trustworthy the person perceives the reward-giver to be, according to a new study….”
A Game of Homs – “What striking about Syria is how so many people insist on speaking about it in profoundly moralistic, Manichaean terms. This is complete nonsense, given that its civil war isn’t a showdown between democracy and dictatorship, but an ethnic and religious conflict. Here’s a more realistic guide.” – really good stuff from anatoly!
America’s greatest days lie ahead – provided she is true to herself – t.greer says: “Daniel Hannan(!) reviews America 3.0 and its Emmnauel Todd theory of America.”
Children with behavioral problems more at risk of inflammation – “Children with behavioral problems may be at risk of many chronic diseases in adulthood including heart disease, obesity, diabetes, as well as inflammatory illnesses (conditions which are caused by cell damage).”
Slaughtered bodies stripped of their flesh – a gruesome glimpse of Iron-Age massacre at UK’s largest hill fort – “Hundreds if not thousands stripped of their flesh and chopped up, say archaeologists.”
Carbon dating shows ancient Egypt’s rapid expansion – “The powerful civilisation of ancient Egypt took just a few centuries to build, according to a radiocarbon dating study that sets the first solid chronology for the period…. Archaeologists have assumed it developed gradually from the pastoral communities that preceded it, but physicist Mike Dee from the University of Oxford and his colleagues now suggest that the transition could have taken as little as 600 years.” – see also A chronology of ancient Egypt @dienekes’.
Declassified spy photographs reveal lost Roman frontier – “Declassified spy photography has uncovered a lost Roman Eastern frontier, dating from the second century AD. Research by archaeologists at the Universities of Glasgow and Exeter has identified a long wall that ran 60 kilometers from the Danube to the Black Sea over what is modern Romania. It is considered the most easterly example of a man-made frontier barrier system in the Roman Empire.” – trajan’s rampart!
Melting Snow Reveals Iron Age Sweater – “A boat neck sweater made of warm wool and woven in diamond twill was a dominating fashion trend among reindeer hunters 1,700 years ago, according to researchers who have investigated an extremely well preserved Iron Age tunic found two years ago under melting snow in Norway.”
