This is interesting:

Humans have moved into the evolutionary fast lane and are becoming increasing different, a genetic study suggests.

In the past 5,000 years, genetic change has occurred at a rate roughly 100 times higher than any other period, say scientists in the US.

This is in contrast with the widely-held belief that recent human evolution has halted.

The research has been published in the Proceedings of the National Academy of Sciences (PNAS).

Professor Henry Harpending, an author of the study from the University of Utah, Salt Lake City, US, said: “The dogma has been these [differences] are cultural fluctuations, but almost any temperament trait you look at is under strong genetic influences.

“Genes are evolving fast in Europe, Asia and Africa, but almost all of these are unique to their continent of origin,” he added. “We are getting less alike, not merging into a single, mixed humanity.”

Fascinating.
