Human MtDNA Diversity Before Migration Out Of Africa
Interestingly, the results also suggest that there was little to no intermingling of these branches for the next 50,000 to 100,000 years! The L0 branch comprises 60% of the Khoisan people (two ethnic groups named the Khoi and the San) of Southern Africa. The L1 5 branch comprises all other branches of the mtDNA tree, which includes the N and M matrilines that eventually spread out from Africa. The results of the study also suggest that humanity was once comprised of a relatively small number of individuals (as few as 2,000, according to another study cited by the researchers).
