Common Ancestor or Direct Descendent?

WHERE AND WHEN DID WE EVOLVE?

What is the Origin of Modern Human Populations? Multiregional Hypothesis Homo sapiens evolved from an ancient stock of Homo ergaster/erectus that originated in Africa (~ 1-1.8 mya) Out of Africa Hypothesis Homo sapiens evolved from a relatively recent stock of archaic sapiens that originated in Africa (~ 30,000-200,000 ya)

Multiregional Hypothesis How Can We Test These Hypotheses With Archaic and Contemporary Morphological Data? Multiregional Hypothesis Predicts greater morphological similarity between archaic and modern Homo within regions Out of Africa Hypothesis Predicts greater morphological similarity between modern forms from different regions than between modern and archaic forms within regions

Neanderthals are distinct from Homo sapiens
