The Multiregional model

The multiregional model An Opposing View of the Dispersal of Homo Sapiens

Basic facts which both models agree on.

•         Hominins first left Africa and established populations in other parts of the world (first southern Asia, China, and Java, later Europe) by 1.8 million years ago.

•         Humans today are quite different anatomically and behaviourally from archaic people (that is, most humans before 40,000 years ago) anywhere in the world.

•         Human populations today are genetically very similar to each other.

•         African populations today are more genetically diverse than populations in other parts of the world.

•         Recent humans in Europe and Asia share a few features with the ancient archaic people who lived in those places before 40,000 years ago.

The multiregional model.

•         Around 1.8 million years ago, Homo erectus left Africa and dispersed across the globe.

•         Over time Homo erectus evolved gradually through other forms of archaic human to become Homo sapiens.

•         This process occurred across the range of Homo erectus.

•         Homo sapiens therefore did not originate solely in Africa.

•         At a basic level, Homo erectus always evolves into Homo sapiens, wherever it lives across the globe.

•         In an extreme form,…
