A new, comprehensive review of humans’ anthropological and genetic records gives the most up-to-date story of the “Out of Africa” expansion that occurred about 45,000 to 60,000 years ago.
This expansion, detailed by three Stanford geneticists, had a dramatic effect on human genetic diversity, which persists in present-day populations. As a small group of modern humans migrated out of Africa into Eurasia and the Americas, their genetic diversity was substantially reduced.
In studying these migrations, genomic projects haven’t fully taken into account the rich archaeological and anthropological data available, and vice versa. This review integrates both sides of the story and provides a foundation that could lead to better understanding of ancient humans and, possibly, genomic and medical advances.
