[Cronos]

Sub-Saharan Africa is 99% black, not because few white people have happened to wander there

Sub-saharan Africa is 99% black/Negroid BECAUSE NO white/Caucasians managed to cross the dividing Sahara desert in any great numbers. When they did, they formed Arabic desert states. Ditto in the East, white/Caucasians from Central Asia/India/Persia moved into China -- the Tocharian culture but never managed to get past the Gobi desert or Siberia.

Sub-saharan Africa is 99% black/Negroid BECAUSE NO white/Caucasians managed to cross the dividing Sahara desert in any great numbers.

Caucasians at one time or another colonized most of Africa (by boat, not through the Sahara) yet they are 1% of the population there. America was also a colony yet Caucasians are 75% of the population here. What was the difference?
