Chapter 20: Human Evolution

African Replacement Hypothesis

H. Sapiens evolved in Africa, then migrated to Europe and Asia, H.sapien replaces local without hybridization. No genes from these early populations persist in modern human populations

Hybridization and Assimilation

H. sapiens evolved in Africa, then migrated to Europe and Asia, H.sapiens largely replaced the local population. Hybridization between newcomers and residents. Genes from local populations were assimilated and persist in Modern Human populations

Multiregional Evolution Model

H Sapiens evolved concurrently in Europe, Asia, and Africa. Sufficient gene flow among populations to maintain their continuity as a species. The gene pool is derived from a mixture of distant and local populations

Candelabra Model

H Sapiens evolved independently in Europe, Asia, and Africa. No gen flow among populations

Catarrhini

Humans belong to the __________ suborder of primates
