The
common chimpanzee (
Pan troglodytes), also known as the
robust chimpanzee, is a species of
great ape. Colloquially, the common chimpanzee is often called the
chimpanzee (or "chimp"), though this term can be used to refer to both
species in the
genus Pan: the common chimpanzee and the closely related
bonobo, formerly called the pygmy chimpanzee. Evidence from fossils and DNA sequencing shows both species of chimpanzees are the
sister group to the modern
human lineage.
