[Albion Wilde]

The oldest human mtDNA (mother's side) is haplogroup L. It split into L0 and L1-L6. L1-L6 kept diversifying, more or less. Non-africans trace back to L3. L0 did not diversify except into sub-clades and is heavily represented in South Africa.

I would like to understand what you are sharing, but anthropological terminology is outside of my field. Can you explain it a little more for laypersons reading here?

"A haplogroup is a genetic population group of people who share a common ancestor on the patriline or the matriline." The mtDNA is along the matriline. The main sub-Saharan haplogroups are L0, L1, L2, and L3. Some say L0 is extinct, some combine it with L1, others keep them separate.

Through mutation, natural selection (positive and negative), the groups evolve. All non-African groups came from L3 through N, including H, V, and others common in Africa. M went east to give us G, Y and others including those in Native Americans.

Some say this makes the younger haplogroups more evolved. What you take from that is up to you.
