Chimpanzee

Pan troglodytes

The Chimpanzee and its relative the Bonobo are more closely related to humans than to any other ape. Chimpanzee communities number from 20 to 105 apes, but group members will wander alone or in small parties searching for food. They will travel on the ground between trees and bed down wherever darkness overtakes them. When they do assemble in larger parties, it is to share a food source like a fig tree in fruit. Chimpanzees make tools out of grass stems to "fish" for termites, and make hammers and anvils to crack nuts.
