Would like to see a more thorough analysis with a broad database of people from the same region. For example Yemen and Ethiopia have long ties, is the gene pool in Yemen classified as Arab? Some of the DNA services don't have deep data from certain regions
How far back are these ties? Ethiopia has existed as a community for 1000s of years, if we go there many people in Europe will be classified by where they migrated from. In that case would Saxon genes place the subject as German?
All that said the Ethiopian community is making moves.
