Darwin's primary legacy, the theory of evolution, has robustly withstood years of scientific challenges. But now a team of Stanford researchers has published a paper in Science claiming they can top Darwin's second monster: sexual selection theory.

The Stanford group says sexual selection theory wrongly models interactions between the sexes as competitive. The group has a new theory, social selection, which models mate selection as a cooperative game where parties seek to maximize group welfare.
