Switzerland. Geneva. An old woman walks in the street and passes-by a derelict building with walls covered with graffitis. A chimpanzee and a black african man. Chimpanzees, sometimes colloquially chimps, are two extant hominid species of apes in the genus Pan. Chimpanzees are members of the family Hominidae, along with humans. Chimpanzees split from the human branch of the family about four to six million years ago. 16.03.14 © 2014 Didier Ruef
