Document Summary
Analogies: similar outcome in different lineages due to common evolutionary pressures. Jane goodall was the first human to be accepted by wild chimpanzees. What she discovered revolutionized our concept of chimps, and of ourselves: a second species of chimpanzees were studied by takayoshi kano, called bonobos. Sometimes chimps have to hunt in groups when other mammals are very small compared to their size, and when they can"t get into the trees to catch them. The only way to solve this is by hunting in groups: bonobos, females play a very different role in bonobo society than they do among chimps. The reigns of power are shared equally among males and females, held by a strong bonded group of high-ranking mothers and their adult sons. Instead of fighting, bonobos have sex to diffuse aggression. In this genuine making love not war society, bonobos have largely divorce sex from its reproductive role.
