A surprising link between Africans and Denisovans and More on the surprising link between Africans and Denisovans – from dienekes.

Burn victim identified by maggots on body“When Mexican police found a body in the woods it was burned beyond recognition, its DNA too damaged to be used for identification. Luckily, investigators were able to extract DNA from elsewhere – the digestive systems of maggots that had been feeding on the body. This is the first time that human DNA from a maggot gut has been analysed in this way to successfully identify a victim in a legal case.”

The Marketplace in Your Brain“Neuroscientists have found brain cells that compute value. Why are economists ignoring them?”

Trans-species polymorphisms“It’s not just that we see the same gene in distantly related species. We also see the same gene with the same set of alleles—a trans-species polymorphism (Klein et al., 1998). A good example is the ABO blood group system. On the basis of that gene marker, I probably have more in common with certain apes than I do with some of my readers.” – (^_^) from peter frost.

bonus: I’m Spantacus! Slave ants rebel“[O]n average 95 per cent of the parasitic ant larvae survived to pupa stage – but then the slave ants attacked or neglected them. Only 45 per cent of the parasite’s offspring survived to adulthood. In comparison, the survival rate for host pupae in their own free-living nests is 85 per cent.”

  2. “Ancient stinging nettles reveal Bronze Age trade connections”

    Similar findings, discovered for Pre-Columbian Americans, are often used to ‘prove’ that American-Indians were actually superior to backwards contemporaneous Europeans, a popular left-wing talking point.

    It’s fun to watch the Amerindian Supremacists (most of whom are White by race but ‘SWPL’ by allegiance) defend the obviously-inferior aspects of Amerindian cultures. No culture in the Americas in 1491 had the wheel, for instance. Imagine being in the position of having to defend the superiority thesis, when someone brings up the Wheel issue.
