[ via Nalo ] Human female promiscuity is a valid evolutionary strategy, according to some recent work:
Anthropologists claim, good judgment aside, evolution has nudged women a bit toward promiscuity and sexual adventure. In all well-studied primates, females exhibit a polyandrous tendency when given the opportunity to stray. Some who cheat appear to be more fertile, and the offspring of most are more likely to survive. Fooling around appears to have helped our ancestral mothers equip their little ones for success — the sexual equivalent of reading to them every night or enrolling them in the after-school chess club.
