The closest living relatives of humans are chimpanzees (genus Pan) and gorillas (genus Gorilla).

Chimpanzee, sometimes colloquially chimp, is the common name for the two extant hominid species of apes in the genus Pan.

The genus Pan is considered to be part of the subfamily Homininae to which humans also belong.

A less frequent usage includes the two species present-day of the genus Pan (the Common Chimpanzee and the Bonobo).

Proconsul africanus had a brachial index of 96 which is comparable to the extant genus Pan.

Chimpanzees and bonobos are closely related to each other and they represent the two species in the genus Pan.

Some earlier classification schemes include the genus Pan (chimpanzees) within the Hominini, but this classification is now rarely followed.

Molecular evidence further suggests that between 8 and 4 Ma, first the gorillas, and then the chimpanzee (genus Pan) split from the line leading to the humans.

Chimpanzees are great apes of the genus Pan.

The closest relative among the other living Primates, the genus Pan, represents a branch that continued on in the deep forest, where the primates evolved.
