A simplified scenario of early human migration routes and dates. Modern humans originated in Africa, probably around 200,000 years ago (200 KYA). One or more routes out of Africa are possible, but the number of individuals involved was very limited, with perhaps only 600 females. Migration probably followed a coastal route, with humans arriving in the Indian subcontinent about 70,000 years ago. The analysis by Shi et al. [2] suggests that humans arrived in southern East Asia around 60,000 years ago and then proceeded north to occupy northern East Asia and Japan.
