Multi-Regional and Partial

Replacement Hypothesis.

A. Multiregional Evolution Model

- Old world populations (in and out of Africa) continued evolutionary development

(though an archaic phase) into anatomically modern human (REGIONALLY)

- Support: would need continuity in the fossils from Africa, China and South-east

Asia (from H. erectus, through archaics, all the way to moderns.)

- Only way model works at all assumes extreme gene flow

- Almost no one supports this

B. Partial Replacement (Hybridization) Model

- Middle of road hypothesis
