'People like to think of modern human biology, and especially mental biology, as being the result of selections that took place 100,000 years ago,' said University of Chicago geneticist Bruce Lahn. 'But our research shows that humans are still under selection, not just for things like disease resistance but for cognitive abilities.'
Lahn recently published the results of a study demonstrating that two key genes connected to brain size are currently under rapid selection in populations throughout the globe."
