Chimpanzees lack the prominent sagittal crest and associated head and neck musculature of gorillas. [14] [41] Chimpanzee hand (left) compared to human hand. Chimpanzee bodies are covered by coarse hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Chimpanzees lose more hair as they age and develop bald spots.
Existing chimpanzee populations in West and Central Africa are separate from the major human fossil sites in East Africa; however, chimpanzee fossils have been reported from Kenya, indicating that both humans and members of the Pan clade were present in the East African Rift Valley during the Middle Pleistocene.
The central chimpanzee averages 59.7 kilograms (132 lb) in males and 45.8 kilograms (101 lb) in females. [4] Standing they measure on average 96 cm (38 in) for males and 80 cm (31 in) for females. Central chimpanzees usually have a lifetime in captivity of 30 to 40 years, but some have been seen to live over 50 years. In the wild, the average ...
The bonobo (/ b ə ˈ n oʊ b oʊ, ˈ b ɒ n ə b oʊ /; Pan paniscus), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus Pan (the other being the common chimpanzee, Pan troglodytes).

The chimpanzee's body is covered with coarse black hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Both of its thumbs and its big toes are opposable, allowing a precision grip. Like most chimpanzee populations, the eastern chimpanzees have amber to brown irises and dark sclerae.
Homininae (the hominines), is a subfamily of the family Hominidae (hominids). (The Homininae— / h ɒ m ɪ ˈ n aɪ n iː / —encompass humans, and are also called "African hominids" or "African apes".) [1] [2] This subfamily includes two tribes, Hominini and Gorillini, both having extant (or living) species as well as extinct species.
The western chimpanzee or West African chimpanzee [1] (Pan troglodytes verus) is a Critically Endangered subspecies of the common chimpanzee. It inhabits western Africa, specifically Côte d'Ivoire , Guinea , Liberia , Mali , Senegal , Ghana , Guinea-Bissau , but has been extirpated in three countries: Benin , Burkina Faso , and Togo .
Biologists classify humans, along with only a few other species, as great apes (species in the family Hominidae).The living Hominidae include two distinct species of chimpanzee (the bonobo, Pan paniscus, and the chimpanzee, Pan troglodytes), two species of gorilla (the western gorilla, Gorilla gorilla, and the eastern gorilla, Gorilla graueri), and two species of orangutan (the Bornean ...
