when are hominids now thought to have differentiated from the ancestors shared with the african apes
Hominidae Within the taxon Hominidae, a number of extant and known extinct, that is, fossil, genera are grouped with the humans, chimpanzees, and gorillas in the subfamily Homininae; others with orangutans in the subfamily Ponginae (see classification graphic below). The most recent common ancestor of all Hominidae lived roughly 14 million years ago,[5] when the ancestors of the orangutans speciated from the ancestral line of the other three genera.[6] Those ancestors of the family Hominidae had already speciated from the family Hylobatidae (the gibbons), perhaps 15 million to 20 million years ago.[6][7]
