In any case, it is likely that the ancestors of the African apes, australopithecines and humans,…
The Human Journey: Migration Routes
When humans first ventured out of Africa some 60,000 years ago, they left genetic footprints still visible today. By mapping the appearance and frequency of genetic markers in modern peoples, we create a picture of when and where ancient humans moved around the world. These great migrations eventually led the descendants of a small group…
