Skull Fossil Suggests Simpler Human Lineage“Early, diverse fossils — those currently recognized as coming from distinct species like Homo habilis, Homo erectus and others — may actually represent variation among members of a single, evolving lineage. In other words, just as people look different from one another today, so did early hominids look different from one another, and the dissimilarity of the bones they left behind may have fooled scientists into thinking they came from different species.” see also: Skull of Homo erectus throws story of human evolution into disarray @the guardian. see also john hawks: The new skull from Dmanisi. and greg cochran: All One Species?

speaking of species: Roe Deer × Domestic Sheep“This rather distant cross, which represents a case of interbreeding between separate mammalian families (Cervidae × Bovidae) was reported in the last decade of the 18th century by the Finnish academic Carl Niklas Hellenius (1745-1820), also known as Carl Niklas von Hellens (or af Hellens).” – say what?!

Mysterious Ancient Human Crossed Wallace’s Line“Scientists have proposed that the most recently discovered ancient human relatives — the Denisovans – somehow managed to cross one of the world’s most prominent marine barriers in Indonesia, and later interbred with modern humans moving through the area on the way to Australia and New Guinea.”

Mysterious Minoans Were European, DNA Finds“The Minoans, the builders of Europe’s first advanced civilization, really were European, new research suggests…. ‘They were very similar to Neolithic Europeans and very similar to present day-Cretans,’ residents of the Mediterranean island of Crete.”

People Born With Certain Gene More Likely to Suffer Cognitive Decline After Heart Surgery“Long-term memory loss, difficulty understanding verbal or written communication or impaired ability to pay attention may still occur five years after heart surgery if a patient has a certain gene variation…. This gene was found to be related to a decline in cognitive capabilities compared to those who do not have the variation…. ‘Our study found that if a patient has this gene variation (APOE4), that person is more likely to have cognitive decline five years after surgery.'” – h/t hbd bibliography!

Genetics of eye colours in different rural populations on the Silk Road“[R]egression tree analysis showed that individuals carrying a given combination of haplotypes have a significant probability to show a blue or green/grey iris colour as compared with brown, with a gradient from west to east.” – h/t neuroskeptic!

Scanning for Recent Human Evolution

Evolution is not a one-way road towards complexity“[T]he fact that the highly complex larval muscular bodyplan is so similar in both groups [aplacophorans and chitons] but is only carried over into the adult stage in one of them — the chitons — strongly suggests that the common ancestor of both groups was of similar complexity; thereby implying that the worm-like groups lost these complex traits and became secondarily simplified over evolutionary time.”

What I actually said about genes, IQ and heritability“Rational public debate about genes and intelligence…has proved impossible in Britain and America….”

Heritability estimates and the analysis of variance“In terms that R.A. Fisher might have used, if you plant different strains of wheat in uniformly well ploughed, well mixed, well fertilised soil, then the differences between the different strains will be due to their inherent qualities, and not the vagaries of the soil. On the other hand, if the soil varies considerably then the yields will vary partly because of seed quality, and partly because of soil quality.” – from dr. james thompson.

Intelligence is just another privilege you inherited from mummy and daddy“[I]t is considered bad form for the clever to point out that their advantage is inherited. Yet this has the effect of giving the intellectually privileged the false idea that they have earned their advantage, and eroding the feeling of *noblesse oblige* that the wealthy once felt when they knew their fortune depended on luck. Rather we should regard intelligence as just another privilege you inherit from mummy and daddy…. That would make the world a more, not less, just place.” – from ed west.

US regions exhibit distinct personalities, research reveals“Americans with similar temperaments are so likely to live in the same areas that a map of the country can be divided into regions with distinct personalities, according to new research published by the American Psychological Association. People in the north-central Great Plains and the South tend to be conventional and friendly, those in the Western and Eastern seaboards lean toward being mostly relaxed and creative, while New Englanders and Mid-Atlantic residents are prone to being more temperamental and uninhibited, according to a study published online by APA’s Journal of Personality and Social Psychology.”

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!

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.”

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.
