The story of human evolution (according to the most prominent theory proposed by Darwin) traces our biological origins across seven million years, from the split with chimpanzees to the appearance of anatomically modern Homo sapiens around 300,000 years ago.

The story of human origins rests on evidence so fragmentary that all of prehuman evolution could fit into the back of a pickup truck. Every fossil hominin ever discovered, representing millions of years and countless generations, would barely fill a small room.
