@wallischris10 welcome to the forum. I saw your comment on: Did All Species Arise about 200,000 Years Ago?. We can pick up the question here. You found Jeanson’s article on this paper.
I’d be curious to hear @Joel_Duff’s thoughts, but it appears there is an error in all this. Mitochondrial coalescence does not imply a bottleneck. Why would we grant that?
