Another topic to add to this why has there there never been an all black successful civilization? I mean had the ancient African built a great empire and subjugated the Europeans it would all look different now.
My theory is civilized development is tied to external requirements. If a tribal hunter gatherer society is adequate than you never advance. (For instance, I live in Hawaaii and I can see why they never modernized, it's perfect all year round)
The earliest civilians evolved around flood plains(Egypt, Mesopotamia, Indus River) in order to properly use the limited resources people were forced to work together. Then as people populated temperate climates learning how to essentially survive the winter pushed people toward technological advances.
None of these scenarios existed in Africa or even the Amazon.
