Document Summary
And sexual interactions occur more often among bonobos than among other primates: despite the frequency of sex, the bonobos rate of reproduction in the wild is about the same as that of the chimpanzee. A female gives birth to a single infant at intervals of between five and six years. The split between the human line of ancestry and the line of the chimpanzee and the bonobo is believed to have occurred a mere eight million years ago. The subsequent divergence of the chimpanzee and the bonobo lines came much later. In contrast, bonobos probably never left the protection of the trees. Their present range lies in humid forests south of the congo river, where perhaps fewer than 10,000 bonobos survive. If this evolutionary scenario of ecological continuity is true, the bonobo may have undergone less transformation than either humans or chimpanzees.
