Compare and contrast the Out of Africa (replacement) hypothesis of modern human origins with the Multiregional (continuity) hypothesis. Describe the main points of each as presented in the textbook. What does each say about the where and when of the origins of modern humans? What does the fossil evidence say? What does the genetic evidence say? How does the assimilation model blend elements of these two hypotheses? What is "leaky replacement" and what is the evidence for it?
