Chimpanzees are a type of ape that is more closely related to humans than to gorillas. They live in Africa. Chimpanzees are very intelligent and are good at problem solving and using simple tools. They are very social animals which live in groups of 15 to 100 called communities, lead by a dominant male called the “Alpha” male.

The bonobo (Pan paniscus), formerly called the pygmy chimpanzee and less often the dwarf or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus Pan; the other is Pan troglodytes, or the common chimpanzee. Although the name "chimpanzee" is sometimes used to refer to both species together, it is usually understood as referring to the common chimpanzee, whereas Pan paniscus is usually referred to as the bonobo.
