My sense exactly.
That, also, is likely to not hold up when we start looking at genomic data. Because mtDNA is a single locus, without recombination, it is going to be subject to things like Muller’s ratchet and all the limits a stochastic single measurement.
For example, looking at mDNA for humans and Neanderthals, you’d think they were totally isolated species. Look at their genomic DNA, and you see interbreeding. No surprise, as genomic DNA is much more loci, with recombination, and a much more sensitive test.
Btw @Joel_Duff, great to see you. Looking forward to discussing the Genealogical Adam with you all.
