Translation: "I will be back again, dumb as stump, talking out of the other side of my mouth, citing evidence obtained by methods I have denounced."
I have been troubled that the questions raised by the Duke study have been--so far as I know--ignored. At any rate, mtDNA analysis continues to be widely used. I can only shrug and hope that nuclear DNA studies will follow eventually. That, and maybe some of the problems in mtDNA research have been quietly addressed. Maybe nuclear DNA studies have been mostly confirming mtDNA results, which would indicate that the Duke study may have by chance overstated the problem. Just now, I can't tell what's going on but I expect it will be clearer, later.
Some of the hypotheses I personally don't favor (such as Out-of-Africa, the complete replacement version) depend heavily on mtDNA. (But not entirely in the OOA case.) Everyone sooner or later someday hopes that thing A is true versus thing B. Nevertheless, the siren song of hearing what you want to believe must be resisted if you're going after the truth. If you don't know how things are going to come out, it's best to just say so. The trick is not to make a religion out of your preferences. That is the difference between your approach and mine.
Since all you can do regarding my scientific demolition of evolution in Post# 1868 is insult and spout irrelevancies, you clearly are unable to refute my argument and there is no sense continuing this discussion.
