Archaeology breakthrough: Harvard scientists sequence the DNA of 8,000 year old children

This implies present-day Bantu speakers in western Cameroon and across Africa did not descend from the sequenced children’s population.

One individual’s genome includes the earliest-diverging Y chromosome type, found almost nowhere outside western Cameroon today.

The results show that this oldest lineage of modern human males has been present in that region for more than 8,000 years, and perhaps much longer.

Genetic analyses indicate there were at least four major lineages deep in human history, between 200,000 and 300,000 years ago.
