Bonobos are also a species known for odd relationships between female members. Adolescent females, the book reports, often find an older female to pair up with. It looks like they're falling in love. It will be exciting to learn more about what happens to allow an adolescent to widen her network of support. The only reason I mention it here is its outworking in foreign policy.
Chimpanzees make war upon other tribes or groups of chimps.
Bloody battles ensue when groups of foraging chimps encounter one another. But not bonobos. One afternoon, when two tribes met, they sat down near each other in a clearing, and looked at each other. Which suggests an entirely new paradigm for the United Nations. Bonobos have shown us the trap can be broken through female alliances.
