Bonobo

• It shares roughly 98.7% of its genome with humans and is, alongside the chimpanzee, our closest living relative.
• It feeds mainly on fruit, supplemented with leaves, seeds, fungi, eggs and the occasional small vertebrate.
• It lives only in the tropical rainforest south of the Congo River, in the DR Congo.
• comportamientoIt uses sexual contact as a social tool to defuse tension and settle conflicts within the group, beyond its reproductive purpose.
• comportamientoIn recent years wild females have been recorded adopting unrelated infants from another group, a behaviour previously described only anecdotally.
