The Nature article is paywalled.
Unlike the Neanderthal interbreeding that may have been a single event
that resulted in the Neanderthal DNA that modern human populations have
there is pretty good evidence that multiple interbreeding events in
different parts of the world occurred between modern humans and
Denisovans. They identify 4 distinct populations of Denisovans that may have interbred with modern humans. The overhype of the Science Daily article includes South America as a possible place where Denisovans may
have existed, but the evidence for this in the review article was
minimal. They could have made it over to America, but didn't leave much evidence of their existence. Denisovans probably lived through around 5
ice ages in Asia. So there were likely as many chances to get over to America as there was to get to the Philippines and New Guinea. The
review claims that better analytical methods need to be developed to
figure out where the Denisovan DNA came from in South America. The Denisovans interbred with Asians multiple times, and there is even the possibility that the bits of genome came over with genomes coming in
after the European colonization.

Yes there was something called a 'modern human' at the time that
was totally, totally different from these other primitive apish beings.
We know this because Bill and Ted took these guys to the phone booth
next to the Circle K.
