Bonobos
Bonobos are the closest relatives of humans. They are a tiny bit more similar to humans than chimpanzees.
Bonobos live in the dense jungle in the Congo Basin. During a dry phase in Africa’s history, the settlement area of the chimpanzee/bonobo ancestor split into two parts and the groups in these two areas evolved into today’s bonobos and chimpanzees.
Bonobos are somewhat slimmer and more graceful than chimpanzees. Bonobos eat fruit, plant pulp, leaves and occasionally hunt. Tool use has not yet been observed in bonobos.
Bonobo groups consist of several males and females. As with chimpanzees, the females change groups. Within the group, the females dominate the bonobos.
Bonobo females consistently show genital swellings that signal their readiness to mate. Bonobos have a lot of sex with many partners. Males do not succeed in monopolizing females for themselves.
