Another one of those selective facts with BS arguments. Africa has got the highest amount of genetic diversity. Sub Saharan Africa is very different from the rest. For some reason, only the sub saharan individuals were chosen. Also, no one knows what Homo Erectus DNA looked like because there is no intact DNA left from them. We just know Africans due to being the origin had more ancestors than the ones who migrated towards Europe and Asia. The only DNA available for any comparison is from ancient homo sapiens, neandertals, denisovans and unknown ancestors in Africa. What is also true is after population left Africa, they mutated further then mixed among each other + populations who left Africa first like Aboriginies from Australia. Some of those tribes came back into Africa and brought neandertal DNA with them. Neadertals and Homo Erectus themselves originally came from Africa.
The European who emigrated from Africa to Europe don't exist anymore in large parts. They died out. They were replaced by settlers from middle east and mammoth hunters from central Asia. Most of Europeans are around 50% from middle east and 50% from central asia (autosomale DNA). The only true Europeans are Saami from Finnland. Most dominant male line in Europe is R1a1a and R1a1b, they both emerged in central Asia. R* haplotype is from Sibiria.
The scale of phenotypes between Khoi and San is amazing. Have a look at the phenotype variation in Africa:

African Americans don't represent African culture at all, any of it. Their blood is diluted by DNA of European settlers and native peoples of America. They came from certain parts of Africa. They don't have much in common with Africans from Africa at all so any study conducted on Africans in Africa barely relates to African Americans. Most slaves brought to the Americas weren't from bellow the sub saharan line, they were Bantu people. Sub saharan Africans aren't tall or specially strong. They're built like bushmen.

Fitting account name.
never change it.
