Briefly describe the "out of Africa" and "multiregional" views to describe the transition from Homo
erectus to Homo sapiens. What will be an ideal response?
Early modern humans evolved from a single woman in Africa, whose offspring then migrated from
Africa, perhaps as recently as 100,000 years ago, and populated Europe and Asia, driving the earlier
hominid populations to extinction. Alternatively, early modern humans did not have an isolated origin
in Africa, but rather they established separate populations throughout Eurasia. Occasional contact and
interbreeding between these populations enabled our species to maintain its overall cohesiveness while
still preserving the regional differences in people that we see today.
