More specifically, the chimpanzee is classified as Pan troglodytes . Biologically, chimpanzees are more than 98 percent genetically identical to humans. Chimpanzees grow to the size of adolescent humans and reach sexual maturity between the ages of six and ten. Their gestation period is the same as that of humans, and they give birth most often to single offspring, sometimes twins, with whom they form lifelong bonds. They live up to 40 years in the wild and 55 years in captivity.
Chimpanzees share numerous sociological and behavioral traits with humans.
In the wild, they live in small communities and spend their days gathering food, playing, grooming, and resting. They use sticks to get ants and termites out of dirt mounds, and leaves to clean their bodies and to absorb water from holes in trees for consumption.
