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.
The smooth continuity of the human evolution timeline in physical transformation and location isâunfortunately for those who wish humans had not evolvedâa thing of beauty. This page is reference information for the Evolution of Man page. The Evolution of Man page has excerpts from this chart that clearly show the smooth development in time, morphology, brain size, and location from Ardipithecus ramidus to us. A more graphical human evolution timeline chart is at the bottom of this page, though it's not as updated as the list that follows.
