Wait so you’re taking about 10- 8000yrs ago?? That’s disingenuous to say that current Somalis only carry only 10% of ancient Somali ancestry because how do they know going back that far? Do they have a pure sample of ancient Somali dna from 10000 yrs ago to come to this conclusion? Like a control group that we don’t know about? Also with that logic we can safely assume none of the modern populations have more than few %s of the ancient ancestry of where they reside today as virtually every population has migrated in the last 10000 years.
We are talking ~5,000 years ago when the proto-Cushites entered Somaliweyn and displaced the local hunter-gatherers. Prior to that, these groups were unrelated for over 50,000 years. They weren't the same people.
In the period between 8,000 to 2,000 years ago many large population movements happened that completely changed the racial make up of the world. Southeast Asia went from black looking hunter-gatherers to Chinese looking Asians for example in that period or the Bantus from West-Central Africa (roughly East Nigeria) started displacing the Pygmies and Khoisan in Central and South Africa.
We are still waiting on the study that will sequence the human remains of people that lived in Somalia ~7,000 years ago.
In the 1980s, an excavation was done at the Buur Heybe which yielded multiple specimens and two full skeletons. Photos of the excavation. I emailed the man who conducted the excavation out of curiosity of what happened to the samples and if DNA could be extracted from them. Turns out the...
