Emergence of Individuality in Genetically Identical Mice – “Our results show that factors unfolding or emerging during development contribute to individual differences in structural brain plasticity and behavior.” – the nuture side of nature-nuture. – see also Mice, Men, and Fate.

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.

Chinese project probes the genetics of genius – “Bid to unravel the secrets of brainpower faces scepticism.”

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.”

The self-domestication hypothesis: evolution of bonobo psychology is due to selection against aggression – “[T]he self-domestication hypothesis provides a plausible account of the origin of numerous differences between bonobos and chimpanzees, and note that many of these appear to have arisen as incidental by-products rather than adaptations. These results raise the possibility that self-domestication has been a widespread process in mammalian evolution, and suggest the need for research into the regulatory genes responsible for shifts in developmental trajectories in species that have undergone selection against aggression.”
