With Basankusu being the last port of substance before the wilderness of the Lopori Basin and the Lomako River—the bonobo heartland—conservation efforts for the bonobo[103] use the town as a base.[104][105].

Oliver fiel durch seine menschenähnliche Schädelform auf Seite 2 — Der Kongo-Fluss trennte wohl Schimpanse und Bonobo Wie der Genom-Vergleich bestätigt, hat sich ihr Erbgut seit der evolutionsgeschichtlichen Trennung nicht mehr vermischt. Bonobos and Chimpanzees both share close to 98% of their genome in common with humans, meaning that their genomes are more similar to that of humans than they are to that of gorillas. [54][59] The most common form of male–male mounting is similar to that of a heterosexual mounting: one of the males sits "passively on his back [with] the other male thrusting on him", with the penises rubbing together due to both males' erections.
