Multiregional vs. Out of Africa | john hawks weblog: "Both hypotheses have to account for the same basic set of facts:
Humans 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 behaviorally from archaic people (that is, most humans before 40,000 years ago) anywhere in the world. Recent people are called "modern" humans.
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."
