Chimpanzees (sometimes shortened to chimps) represent our closest living relative, sharing 98% of our genetic DNA.


Do chimps live in groups?

Chimps live in vast social communities, consisting of up to about 100 individuals and comprising of several family groups. They have strict hierarchies, with one dominant alpha male.


How do chimps get round?

They get around by by swinging through trees and by walking on all fours (knuckle-walking), but they can also walk upright on two feet if they want to.

Females will reach reproductive maturity by age 13 and can give birth at any time of the year, usually to one baby. The infant will cling tightly to its mother’s fur, and then takes rides on her back until two years of age.


Can chimps use tools?

Are chimps in danger?

Chimpanzees are classed as Endangered on the IUCN Red List – numbers are decreasing because of habitat loss and fragmentation, killing for bushmeat and the infant pet trade and disease.


Are chimps and bonobos the same?

Chimpanzees are one of only two species in the genus Pan, the other being the bonobo, and both are found sub-Saharan Africa. It was once thought that chimpanzees and bonobos were one species, but they are now recognised as two distinct species.


The chimpanzee (Pan troglodytes) is found north of the Congo river and is split into 4 sub-species. The bonobo (Pan paniscus) is found south of the Congo river and has not been split into any sub-species.
