Now we're in the midst of the next mutation in evolutionary theory: Human evolution didn't slow as we advanced from nature to culture. It accelerated and changed. Culture, born of natural selection, became natural selection's driving force.
This is the message of a new study of the human genome. If true, it radically complicates the debate between nature and nurture. The question is no longer simply whether our genes are the source of civilization, but whether they're also its product.
