>Australian Abos were genetically isolated for at least 50k years before European contact
No. Humans have inhabited Australia for 50k years - this population only became isolated within the last 11.5k-25k, when Sundaland-Sahul experienced a massive flood caused by volcanism and glacial melting.
>The San people diverged 200k years ago
Africans and non-Africans probably diverged 220k years ago based on the dubious Out-of-Africa hypothesis. Y-haplogroup A00 is 338k years old, and all non-African males are descended from BT.
>Behavior Modernity occurred 40-50k years ago
Based on the Levallois technique, it's probably more like 400k years old;

See pic. The name of the paper is 'A high-coverage Neandertal genome from Vindija Cave in Croatia.'
Heterozygosity directly measures how inbred a person or population is, because inbreeding prunes the diversity of alleles which are inherited. Each person inherits two alleles, one from each parent - inbreeding quickly makes these two alleles identical, lowering heterozygosity and increasing homozygosity.
As you can see, Africans have a higher heterozygosity than non-Africans. This implies that;
1: Non-Africans have been subject to founder effects which narrowed their genetic diversity,
2: This involved a diverse population becoming inbred after leaving Africa, or more likely - a handful of people left Africa and had sex with their own sisters.
Basically, the best and brightest created inbred families, and this improved them and led to greater diversity in pigmentation, facial and skull shape, etc than seen in the wild human.
