Researchers have assembled the complete genome of the bonobo. Some details learned so far:
"Bonobos and chimps — which are very closely related but behave in strikingly different ways, with bonobos relying on sex and chimpanzees relying on aggression to resolve conflict — split from each other about 1 million years ago.

Or perhaps the shared ancestor was more like a bonobo, with some other consequence for human traits. "What branch do humans come from? Is it 'Make love, not war,' or 'Make war, not love'?" wondered John Hawks, an anthropologist at the University of Wisconsin."
