I can't answer your question.
I have read that Denisovian DNA is the most completely/thoroughly examined DNA in the world though.
Denisovan Find Hints The Extinct Humans Colonized The ‘Roof of the World’
I read your link and several questions came to mind. Since the Denisovans may have had an adaptation for high altitude living, have the people of the high Andes been tested for Denisovan genes? They are said to have very large teeth. I have very large molars (D) and shoveling of two upper lateral incisors (N). My maternal grandmother came from the petit aristocracy of East Prussia which no doubt had some blood lines from the conquering Mongols. I know that if you go to some of the popular DNA testers they will give you your Neanderthal DNA percentage. Are there any that now give Denisovan figures?
