The Denisovan DNA

I think there's a huge story to tell in America, and I'm intending if the universe allows. For decades it was held that there were no human beings in America before 13,000 years ago. Now we know that there were other human species like Neanderthals or people called the Denisovans. The places in the world today where Denisovan DNA survived most strongly are amongst Native American Indians and amongst Aborigines in Australia.
