Human Evolution Enters an Exciting New Phase“In the most massive study of genetic variation yet, researchers estimated the age of more than one million variants, or changes to our DNA code, found across human populations. The vast majority proved to be quite young…. ‘Most of the mutations that we found arose in the last 200 generations or so….’ said geneticist Joshua Akey of the University of Washington, co-author of the Nov. 28 Nature study. ‘We have a repository of all this new variation for humanity to use as a substrate. In a way, we’re more evolvable now than at any time in our history.’ – i think greg cochran and henry harpending are now permitted to say — “we told you so!” — as much as they like and as often as they like. even to the point when it becomes annoying.

Native Americans and Northern Europeans more closely related than previously thought“According to Nick Patterson, first author of the report, ‘There is a genetic link between the paleolithic population of Europe and modern Native Americans. The evidence is that the population that crossed the Bering Strait from Siberia into the Americas more than 15,000 years ago was likely related to the ancient population of Europe.'” – see also peter frost.

Expectations and reality: a window into the liberal-conservative baby gap“Genotypically, White Americans are getting more conservative, and the future will come to be dominated them (and the non-White groups in the country).” – from jayman.

The Beatings Will Continue Until Morale Improves – from malcolm pollack.

Ancient poo gives clues to human impact on environment“Researchers were able to use prehistoric poo to establish the presence and size of a population dating back over 7,000 years.”
