Document Summary
Ranges for h ergaster and h erectus vary -> best to know dates for subspecies. Point at which they end -> depends if you subscribe to multiregional model or regional continuity model. Amh origins -> under multiregional framework there was only one migration out of africa into georgia, e and se asia about 1. 7-1 mya. Reason they moved -> maybe because of envr change, following resources we don"t know. Went on to develop into amh in each of the varied parts of the world in which they settled. > regular gene flow between pops in these regions would"ve been necessary to maintain species diversity. We don"t know exactly how and why they evolved into amh. Recent african origins (rao model) most subscribed model. Amh evolved in africa by those hominins that stayed -> h erectus pops in other parts of the world remained evolutionary static.
