Having jus listened all the way through the article, I have a couple of comments/questions.
It seems reasonable to me that homo sapienssapiens, whatever the correct description is, might well have been around for longer than conventional history states.
Do you think the Denisovans were a separately evolved branch of ancestor apes from homo sapienssapiens, but with enough similarity to still be able to breed with homo ssapienssapiens?
Have the various archaeological findings of, say bones, beenn established as being of this apparent race of Denisovans rather than from a deformed homo s-s one?
I wish I could see the long thin blade you describe. It is so interesting that artistry was so evidently a strong survival skill of all brances of humans.
