This timeline of prehistory covers the time from the appearance of Homo sapiens approximately 315,000 years ago in Africa to the invention of writing, over 5,000 years ago, with the earliest records going back to 3,200 BC. Prehistory covers the time from the Paleolithic (Old Stone Age) to the beginning of ancient history.
