About
The Common Chimpanzee (Pan troglodytes), also known as the Robust Chimpanzee, is a great ape. The name troglodytes, Greek for 'cave-dweller', was coined by Johann Friedrich Blumenbach in his Handbuch der Naturgeschichte (Handbook of Natural History) published in 1779. Colloquially, it is often called the chimpanzee (or simply 'chimp'), though technically this term refers to both species in the genus Pan: the Common Chimpanzee and the closely-related Bonobo, or Pygmy Chimpanzee.
Basic Facts :: Common Chimpanzees are found in the tropical forests and wet savannas of Western and Central Africa. They once inhabited most of this region, but their habitat has been dramatically reduced in recent years. Adults in the wild weigh between 40 and 65 kilograms (88 and 143 lb); males can measure up to 160 centimetres (63 in) and females to 130 cm (51 in). Its body is covered by a coarse dark brown 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. Its gestation period is eight months. Infants are weaned when they are about three years old, but usually maintain a close relationship with their mother for several more years; they reach puberty at the age of eight to ten, and their lifespan in captivity is about fifty years.
Diet :: Although omnivorous, its diet is mainly vegetarian (but eats meat whenever it is available) consisting of fruits, leaves, nuts, seeds, tubers, and other miscellaneous vegetation. There are also instances of organized hunting; in some cases, such as the killing of Leopard cubs, this primarily seems to be a protective effort, since the Leopard is the main natural predator of the Common Chimpanzee. However, meat is a necessary source of nutrient, and the Common Chimpanzee sometimes band together and hunt prey such as the Western Red Colobus Monkeys (Piliocolobus badius). Isolated cases of cannibalism have also been documented, as well as preying on human flesh. The West African Chimpanzee (Pan troglodytes verus) is the only animal besides humans known to routinely create and use specialized tools specifically for hunting. Chimpanzees near Kédougou, Senegal were observed to create spears by breaking off tree limbs, stripping them of their bark, and sharpening one end with their teeth. They then used these weapons to kill galagos sleeping in hollows.
Link with HIV type 1 :: Two types of Human Immunodeficiency Virus (HIV) infect humans: HIV-1 and HIV-2. HIV-1 is the more virulent and easily transmitted, and is the source of the majority of HIV infections throughout the world; HIV-2 is largely confined to west Africa. Both types originated in west and central Africa, jumping from primates to humans. HIV-1 has evolved from a Simian Immunodeficiency Virus (SIVcpz) found in the Common Chimpanzee subspecies, Pan troglodytes troglodytes, native to southern Cameroon. Kinshasa, in the Democratic Republic of Congo, has the greatest genetic diversity of HIV-1 so far discovered, suggesting that the virus has been there longer than anywhere else. HIV-2 crossed species from a different strain of SIV, found in the Sooty Mangabey, monkeys in Guinea-Bissau
