Biology paper - Essay Example Human beings are members of the tribe Hominina together with vanishing species of sub-tribe Hominina. Also, Chimpanzees are the only recognized members of the sub-species Panina. The two species of Panina divided about one million years ago. Chimpanzees display very minimal morphological variances between subspecies. They have a more robust body than bonobos Pan paniscus. Additionally, they are faintly sexually dimorphic. On average, females weigh averagely from 32 to 47 kg (70.5 to 104 lb) while males weigh averagely from 40 to 60 kg (88.2 to 132 lb) (Rowe 1996). Both females and males have a typical height of 816 mm (2.68 ft) (Rowe 1996). The chimpanzee taxonomy hierarchy is as follows; Suborder: Haplorrhini Infraorder: Simiiformes Superfamily: Hominoidea Family: Hominidae Genus: Pan Species: P. troglodytes Subspecies: P. t. schweinfurthii, P. t. troglodytes, P. t. vellerosus, P. t. verus. This essay discusses on the taxonomy of chimpanzee family and their biography. All Chimpanzees are black in color, but have pale faces and a white tail tuft, which later darkens with age. Chimpanzees are seen to have bulkier thick bodies with long arms that lengthen past their knees (Rowe 1996). They also have short legs, large thumbs and no tails. A large portion of their body is protected with long black hair except their faces, ears, fingers, and toes which have skin alone. These living creatures have protruding ears for both males and females, which entails white beards (Rowe 1996). Their movement array encompasses quadruped knuckle walking and irregular bipedalism. Chimpanzees are both land-dwelling and arboreal, with the quantity of time spent on the ground wavering among different case study sites and between sexes. Moreover, Chimpanzees create their sleeping nests in trees when darkness falls (Rowe 1996). A normal life span of chimpanzees is 40 to 45 years. All the same, the life span for captive chimpanzees is
