Overview
The only surviving hominin species. Earliest known fossils are from Jebel Irhoud, Morocco (~315 KYA), with a pan-African origin. Characterized by a globular braincase, reduced brow ridges, prominent chin, and gracile skeleton. Uniquely capable of fully symbolic thought, complex language, and cumulative culture. Dispersed from Africa beginning ~70 KYA, eventually reaching all continents. Interbred with Neanderthals (1-4% DNA in non-Africans), Denisovans (up to 5% in Melanesians), and unknown archaic "ghost" populations in Africa.

Tools & Technology
Associated Tool Traditions
Middle Stone Age
African stone tool tradition roughly contemporaneous with the European Middle Paleolithic. Includes prepared cores, points, and blades. Associated with early H. sapiens and the emergence of symbolic behavior.
