No. It sparked more questions. Why did scientist find ancient DNA (from 3,000 to 8,000 years ago) in West Africa that was matched with ancient East African DNA?
To Dr. Prendergast’s surprise, none of the people at Shum Laka were closely related to Bantu speakers at all.
The fourth group, which Dr. Reich and his colleagues call “Ghost Modern,” is far more mysterious.
The ancient Shum Laka people have a substantial amount of Ghost Modern ancestry. So does the ancient Mota man from Ethiopia. But ancient remains from Morocco and South Africa had none. Today some people in Sierra Leone have a tiny trace of Ghost Modern ancestry, the researchers found.
A separate group of East Africans moved west, encountering and mixing with Central African hunter-gatherers and
eventually becoming the first West Africans. The people of Shum Laka may be the descendants of this group.

I think the next logical question should be what other populations contain this “ghost modern” DNA.
