Hendrina Smit - African mtDNA (L5) a puzzle.

I'm curious re: Private User's L7a via Hendrina Steenkamp versus Private's L0d via Johanna Tol. My grandfather was L0d, my cousin Private User is L0d too. I'm curious how L0d compares with L7a. Especially in terms of its "uniqueness".

Reading the article, the emphasis appears to be on "the oldest singleton branch in the human mtDNA tree". I take that to mean Private User's line has a unique mutation not shared by the other lines. Am I correct this is typical of lines that developed/diverged in isolation i.e. perhaps abrupt (geographical?) isolation, where the other lines continued to develop unabated?

Wow, that's interesting. I'll take a look too..

So, even autosomal DNA descendents, Danielle?

We could start a project and collectively target all of these individuals. Recommend testing to all of them. :D

3054 individuals, not taking into consideration potential zombies etc.

I'm trying to alert mtDNA descendants here - https://www.geni.com/discussions/251987?msg=1573557 - but there are more than I expected :-/

Can get it down to 68 living individuals if we filter for L7a and living status=living:

I've uploaded the longer article for people to look at: https://www.geni.com/documents/view?doc_id=6000000186005154834

Excerpts:
African mitochondrial haplogroup L7: a 100,000‑year‑old maternal human lineage discovered through reassessment and new sequencing.
Here we describe L7, an eighth haplogroup that we estimate to be~ 100 thousand years old and which has been previously misclassifed in the literature. In addition, L7 has a phylogenetic sublineage L7a*, the oldest singleton branch in the human mtDNA tree (~80 thousand years)....

The~80 kya relict sequence L7a* from a primarily European woman of South African matrilineal descent is very intriguing. It exposes the process of lineage extirpation, either due to tens of thousands of years of low Ne, or a recent bottleneck (or both). Given that there is<1% detectable sub-Saharan ancestry in the individual, and the next closest sequence is 80 kya removed, it is imprudent to speculate about the history of this lineage. With time and intensive sampling in southeastern Africa, it is possible more L7a* sequences will be discovered and will help resolve the mystery.

Drummond Corrie too - he did the recommended testing work. Jolly impressive. Hope something comes out of it :-)

That's so exciting. Well done Willem Eugene Basson :-)

My pleasure Private User; piqued my interest. Pleased to know Willem Eugene Basson has tested. Same branch as you, both descendants of Josina Christina Marais.
