The chimp "war"

[Undertoad]

But this scientist says humans are just as closely related to bonobos

and bonobos are basically the sex nuts of the primate world.

Bonobos do not form permanent monogamous sexual relationships with individual partners. They also do not seem to discriminate in their sexual behavior by sex or age, with the possible exception of abstaining from sexual activity between mothers and their adult sons. When bonobos come upon a new food source or feeding ground, the increased excitement will usually lead to communal sexual activity, presumably decreasing tension and encouraging peaceful feeding.

Oh, wow, it's a apple grove! Well, let's all get laid! That way nobody will feel like they have to fight over this fruit!
