Pan Troglodytes

Chimpanzee; three subspecies recognized. Occupies variable habitats ranging from savanna to tropical rain forest throughout western and central equatorial Africa. Sexual dimorphism in both body and canine size; males weigh 56-80 kg, females 45-68 kg. Since the 1960s chimps have been studied extensively; they are considered an important model for early human evolution. Among the findings relating to human evolution are that chimps make and use tools, that they are capable of learning language in a laboratory situation, and that males hunt small mammals; food sharing occurs through begging. Molecular evidence shows that chimp DNA is 98.4% identical to human DNA. The word chimpanzee itself comes from a Congolese dialect and means mock man.
