"The ethio-somali component is a mix of west eurasian and african." But is ethio-somali a mix of Westeurasian+ subsaharan african or a mix of Westeurasian+northafrican? Cause i think I've read somewhere it's northafricanIf we're being frank, it's 40-60, west eurasian and african. This mix happened prehistory. Probably in the neolithic era. A group similar to natufians and the dinka were the mix. The cause was most like forced migration due to the desertification of the sahara and arabia. 5000 years ago it was green.
