Comparison of mtDNA sequences revealed that all humans shared a common mtDNA ancestor around 200,000 years ago. What was the predicted date of the common ancestor under the multiregional hypothesis of modern human origins?

Question

Quizplus · Accepted Answer

The multiregional hypothesis of modern human origins posits that modern humans evolved from earlier human species starting around 2,000,000 years ago, with continuous gene flow between geographically separated populations. This contrasts with the "Out of Africa" model, which suggests a more recent common ancestor.
