In 200,000 BP, Africans (e.g.,
Mitochondrial DNA studies also provide evidence that the San carry high frequencies of the earliest haplogroup branches in the human mitochondrial DNA tree. This DNA is inherited only from one's mother. The most divergent (oldest) mitochondrial haplogroup, L0d, has been identified at its highest frequencies in the southern African San groups.[17][21][22][23]

The genomes of Africans commonly found to undergo adaptation are regulatory DNA, and many cases of adaptation found among Africans relate to diet, physiology, and evolutionary pressures from pathogens.[24] Throughout Sub-Saharan Africa, genetic adaptation (e.g., rs334 mutation, Duffy blood group, increased rates of G6PD deficiency, sickle cell disease) to malaria has been found among Sub-Saharan Africans, which may have initially developed in 7300 BP.[24] Sub-Saharan Africans have more than 90% of the Duffy-null genotype.[28] In the Kalahari Desert region of Africa, various possible genetic adaptations (e.g., adiponectin, body mass index, metabolism) have been found among the ǂKhomani people.[24] Sub-Saharan Africans have more than 90% of the Duffy-null genotype.[28] In South Africa, genetic adaptation (e.g., rs28647531 on chromosome 4q22) and strong susceptibility to tuberculosis has been found among Coloureds.[24]
