If you’re interested. Paleo-africans (Khoisan and Pygmy hunter gatherers) branch of early from the family tree (Y-chromosomes A and B, mtDNA groups L0, L1, L5) around 140-150 thousand years ago. Y chromosome E and mtDNA type L3, long claimed to be african, branch off around 70 kya, around the same time all the other major Y chromosomes and mtDNA groups do (Y chrom. C,D, and F; mtDNA groups M and N. We are supposed to believe that this all happened in Africa and then all the Cs and Ds and Fs left africa en masse, as well as half of the Es and that all of mtDNA groups M and N and half of L3 also left africa and moved in to eurasia. This is a preposterous explanation. This study asserts that the obvious explanation is that these groups left Africa much earlier and differentiated in Asia. Y chromosome E and mtDNA type L3 migrated to the middle east where people still have these types and then some continued back in to africa. There’s a little map that shows the migrations if you don’t want to read the whole thing. https://www.researchgate.net/profile/Vicente-M-Cabrera/publication/325856764_Carriers_of_mitochondrial_DNA_macrohaplogroup_L3_basal_lineages_migrated_back_to_Africa_from_Asia_around_70000_years_ago/links/5b2b913f4585153d2b7b7662/Carriers-of-mitochondrial-DNA-macrohaplogroup-L3-basal-lineages-migrated-back-to-Africa-from-Asia-around-70-000-years-ago.pdf
