How Old Is Man?

Anatomically modern humans, as man or mankind is scientifically known, have existed for approximately 200,000 years. This is according to the oldest known Homo sapiens sapiens fossils ever found: The Omo remains were discovered in Ethiopia, by paleoanthropologist Richard Leakey between 1967 and 1974, then dated in 2004.

Anatomically modern humans are a subspecies of the larger species, Homo sapiens, which includes other extinct subspecies, such as Homo sapiens idaltu, Homo sapiens neanderthalis, Homo sapiens heidelbergensis, Homo sapiens rhodesiensis and Homo sapiens antecessor. The last three listed are considered archaic human groups, while the Neanderthals are a separate group that possibly interbred with early modern human groups.
