No black African society had a written language or a calendar. None used the wheel or practiced joinery or built multi-story buildings. Iron smelting was common but no black Africans built what could be called a mechanical device, even one so simple as a hinge. Africans apparently tamed no animals themselves but received already-domesticated dogs and cattle from north of the Sahara. None used any beast of burden, despite the presence of large mammals that could have been tamed.

Your arguments are futile...Just look at the faces of the people in the artwork, the texture of the hair, bonestructure, etc....None of that is Negroid at all....

Yeah, the presence of red hair in many of the mummies is due to the fact that Caucasians mixed with Blacks.....Right...

It's kind of sad that a people would cling to societies that they have nothing to do with, because every one that they've ever inhabited or moved into has failed miserably..
