You are an fn idiot. Neither the Sumerians NOR people as far off as China wee 'Africans', you stupid troll. Sumerians were West Asians and people in China were EAST Asians. They derived from proto-Eurasian like people, NOT Sub Saharan Africans, and they don't even cluster genetically close to Sub Saharan Africans. What dingleberries you Afrocentric fools are.OP,the Sumerians were of course African,as was everyone else in the ME as far as China at the time. They were craniometrically identified as such almost a 100 years ago,but as usual some people didn't get the memo.
"Marcel Dieulafoy and M. de Quatrefages observed that the craniometrics of the ancient Elamites of Susa indicate that they were Sub-Saharan Africans or Negroes (Dieulafoy,2010).
Ancient Sub-Saharan African skeletons have also been found in Mesopotamia (Tomczyk et al, 2010). The craniometric data indicates that continuity existed between ancient and medieval Sub-Saharan Africans in Mesopotamia (Ricault & Waelkens,2008). "
"We estimate that Eurasian populations split from ancient Africans at 58,000-120,800 years ago, and the divergence time of Europeans and Asians occurred at 35,750-70,500 years ago."
