Note: A more recent taxonomic scheme for apes places humans together with three of the other great apes (gorilla, common & pygmy chimp) under the common family Hominidae, which then branches into two subfamilies: 1. Homininae, which includes modern Homo sapiens and exctinct ancestor species, and 2. Gorillinae, which includes chimpanzees and gorillas. The orangutans, under this scheme, are placed under a different family: Pongidae. Here we follow a more traditional scheme.
