Fast Evolution Produced Human Brain

KurzweilAI had a line to this Guardian Unlimited article discussing Bruce Lahn's research on the sophistication of the human brain.

From the article, "Professor Lahn's research, published this week in the journal Cell, suggests that humans evolved their cognitive abilities not owing to a few sporadic and accidental genetic mutations - as is the usual way with traits in living things - but rather from an enormous number of mutations in a short period of time, acquired though an intense selection process favouring complex cognitive abilities."
