Chimpanzee, often shortened to chimp, is the common name for the two extant species in the genus ''Pan''. The better known chimpanzee is ''Pan troglodytes'', the Common Chimpanzee, living primarily in West, and Central Africa. Its cousin, the [[Bonobo]] or "Pygmy Chimpanzee" as it is known archaically, ''Pan paniscus'', is found in the forests of the [[Democratic Republic of the Congo]]. The Congo River forms the boundary between the two species.

Most adherents to the theory of evolution hold the view that chimpanzees and humans share a close common ancestor, due to their similar natures and physiology. However, there are millions of species that are similar, due to the fact that they share a common habitat and must have similar structures and physiology in order to survive.  

Most biologists hold the view that chimpanzees and humans share a close common ancestor due to molecular, morphological, physiological, geographical and behavioural similarities. Although in some cases [[convergent evolution]] makes for such similarities in distantly related organisms the similarities between humans and chimps include neutral genetic markers that could not be subject to convergent evolution <ref> A.
