Correct me if I’m wrong, but right at the very beginning the paper states that the “amount of diversity that has accumulated in the subhaplogroup over the past 10,300 years suggests that previous calibrations of the mtDNA clock may have underestimated the rate of molecular evolution.”
Notice they don’t even try to justify the 10,300 years—it’s an assumption. Notice also that they are casting doubt on previous calibrations of the mtDNA clock because it doesn’t fit their ASSUMPTIONS! Finally, you should also notice that the paper you posted is an attempt to reconcile mtDNA with said assumptions. Given the above, how exactly does this paper “refute” the Noahitic flood?
