-There is an extremely good chance that the Sumerians where White. Sumer was founded on the Tigris and Euphrates which both have there origin high up in Anatolia which was White at the time. Sumer was also close to Iranian Plateau which again was mostly White; North Africa also received some White migration .   -Sumer was also Non-Semitic .So who where the only other people around the area if they where not Semitic ..       I'd say the Iraqis of today are the descendants of Sumerians.   -Ya right a lot as happened in the last 5000 years....
