Bonobos use sex the way other species use diplomacy

Food arrives, tension rises, and the tension is resolved sexually.

Bonobos share as much DNA with humans as chimpanzees do, and behave nothing like them. Where a chimpanzee troop settles a dispute with violence, a bonobo troop settles it sexually: between males and females, between females and females, between adults and adolescents, in almost every combination, and usually for a few seconds at a time.

Most of it has nothing to do with reproduction. It happens when a food source is discovered, when two groups meet, when an individual is anxious. Female bonobos form coalitions through this contact, and those coalitions are why bonobo society is female-led — the only great ape society that is.
