Last Updated: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture-bearing, upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Modern humans are of the species Homo sapiens. There is evidence that modern humans evolved from various human ancestors like those within the Ardipithecus Group, Australopithecus Group, and the Paranthropus Group.
