Pan

Pan is a genus of great apes, family Hominidae, alongside humans, gorillas and orangutans, comprising two extant species, the chimpanzee, Pan troglodytes, and the bonobo, Pan paniscus, native to sub-Saharan Africa; chimpanzees range further north into West Africa and around the Congo jungle region, while bonobos are confined south of the Congo River. Chimpanzees are somewhat larger, more aggressive and male-dominated, while bonobos are more gracile, peaceful and female-dominated, though both share dark hair, hairless faces and extremities, and arms longer than their legs; genetic studies place Pan as humanity's closest living relative, differing by roughly 1 to 1.2 percent in DNA and diverging from the human lineage an estimated five to twelve million years ago.
