Twelve bonobo facts, fact-checked
Bonobos (Pan paniscus) are, with chimpanzees, our closest living relatives — and behave very differently from them. Full profile in our bonobo guide.
1. As closely related to us as chimpanzees
Roughly 98.7% shared DNA. Bonobos and chimps split from each other around two million years ago.
2. Females lead
Groups are female-dominated, with coalitions of unrelated females outranking individually larger males.
3. They defuse conflict rather than escalate it
Tension over food or territory is commonly resolved through social and sexual contact instead of aggression.
4. They share with strangers
Experiments show bonobos will voluntarily give food to individuals they have never met — behaviour not seen in chimpanzees.
5. Lethal violence is essentially unrecorded
Unlike chimpanzees, coordinated killing between bonobo groups has not been documented.
6. One river decided everything
The Congo River separated the two species. Bonobos live only south of it, in habitat with less competition for food, which likely shaped the difference.
7. They walk upright more readily
Longer legs and a more upright posture than chimpanzees, and they carry objects bipedally more often.
8. Distinctive appearance
Dark faces from birth, pink lips and hair parted centrally — a chimpanzee's face lightens to dark with age.
9. They are Endangered
Bushmeat hunting, habitat loss and civil conflict across their single-country range drive decline.
10. They are hard to count
Insecurity across much of their range makes survey work difficult, so population estimates are uncertain.
11. Their whole range is one country
Found only in the Democratic Republic of the Congo — no other country holds a wild population.
12. They complicate the story we tell about ourselves
Arguments that human aggression is inevitable often cite chimpanzees. Bonobos are equally related to us and behave the opposite way.
