Bonobos and chimpanzees look very similar and both share 98.7% of their DNA with humans—making the two species our closest living relatives. Bonobos are usually a bit smaller, leaner and darker than chimpanzees. Their society is also different—bonobo groups tend to be more peaceful and are led by females. They also maintain relationships and settle conflicts through sex. However, bonobo life isn’t entirely violence free; if two groups of bonobos come together, they may engage in serious fighting.
Wild bonobos can only be found in forests south of the Congo River in the Democratic Republic of Congo (DRC). Sometimes known as the pygmy chimpanzee, bonobos weren’t recognized as a separate species until 1929.
Civil unrest and increasing poverty in the area around the bonobos’ forests have contributed to bonobo poaching and deforestation.
