Seduction: chimp style.

What does a man want when he invites a woman to dinner and why will he always (on the first date at least) try and pay? 

Evolutionary psychologists have suggested that early male hominids traded meat with females for sex and the best male hunters had more sex and more babies. There has been little evidence to support this hypothesis, until now. Primatologists studying wild chimps have found evidence that males do trade meat for sex with females. Christina Gomez one of the scientists stated that:

"Our results strongly suggest that wild chimpanzees exchange meat for sex, and do so on a long term basis. Males who shared meat with females doubled their mating success, whereas females, who had difficulty obtaining meat on their own, increased their calorific intake without the energetic costs and potential risk of injury related to hunting. Previous studies might not have found a link because they focused on short term exchanges, or perhaps in those groups access to females was driven by male coercion so females rarely chose their mating partners. This will have an impact on our studies of men and women"
