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.”

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.”

Mysterious Minoans Were European, DNA Finds“[T]he research team analyzed DNA from ancient Minoan skeletons that were sealed in a cave in Crete’s Lassithi Plateau between 3,700 and 4,400 years ago…. The researchers found that the Minoan skeletons were genetically very similar to modern-day Europeans — and especially close to modern-day Cretans, particularly those from the Lassithi Plateau. They were also genetically similar to Neolithic Europeans, but distinct from Egyptian or Libyan populations.” see also dienekes.

Dogs and Humans Evolved Together, Study Suggests“[B]oth species underwent similar changes in genes responsible for digestion and metabolism, such as genes that code for cholesterol transport. Those changes could be due to a dramatic change in the proportion of animal versus plant-based foods that occurred in both at around the same time, the researchers said. The team also found co-evolution in several brain processes — for instance, in genes that affect the processing of the brain chemical serotonin. In humans, variations in these genes affect levels of aggression.”

Linguists identify 15,000-year-old ‘ultraconserved words’“A team of researchers has come up with a list of two dozen ‘ultraconserved words’ that have survived 150 centuries. It includes some predictable entries: ‘mother,’ ‘not,’ ‘what,’ ‘to hear’ and ‘man.’ It also contains surprises: ‘to flow,’ ‘ashes’ and ‘worm.’ The existence of the long-lived words suggests there was a ‘proto-Eurasiatic’ language that was the common ancestor to about 700 contemporary languages that are the native tongues of more than half the world’s people.”
