Chimpanzee, sometimes colloquially chimp, is the common name for the two extant hominid species of apes in the genusPan. The Congo River forms the boundary between the native habitats of the two species:
Chimpanzees are members of the Hominidae family, along with gorillas, humans, and orangutans. Chimpanzees split from the human branch of the family about four to six million years ago. The two chimpanzee species are the closest living relatives to humans, all being members of the Hominini tribe (along with extinct species of Hominina subtribe). Chimpanzees are the only known members of the Panina subtribe. The two Pan species split only about one million years ago.
A zoo (short for zoological park or zoological garden, and also called a menagerie) is a facility in which animals are confined within enclosures, displayed to the public, and in which they may also be bred.
The term zoological garden refers to zoology, the study of animals, a term deriving from the Greekzōon (ζῷον, "animal") and lógos (λóγος, "study"). The abbreviation "zoo" was first used of the London Zoological Gardens, which opened for scientific study in 1828 and to the public in 1847. The number of major animal collections open to the public around the world now exceeds 1,000, around 80 percent of them in cities.
However, keeping animals in zoos raises concerns for animal rights.
Zoos typically house more wild animals than domesticated ones.
