And what about Denisovan-Human hybrids or Denisovan-Neanderthal-Human hybrids? Its not an either or question - there are numerous combinations.
All three of them are humans, for one thing.
The Denisovan sample came from handful of individuals. I carry Denisovan DNA, along with Neandertal DNA, along with DNA from other archaic specimens. Whatever rattles through the daddy-mommy 50% sieve is what each generation gets and preserves, luck of the draw.
> The fossils of five distinct Denisovans from Denisova Cave have been identified through their Ancient DNA (aDNA): Denisova 2, Denisova 3, Denisova 4, Denisova 8, and Denisova 13. Denisova 11 was an F1 Denisovan-Neanderthal hybrid.[8] An mtDNA-based phylogenetic analysis of these individuals suggests that Denisova 2 is the oldest, followed by Denisova 8, while Denisova 3 and Denisova 4 were roughly contemporaneous.[9] During DNA sequencing, a low proportion of the Denisova 2, Denisova 4 and Denisova 8 genomes were found to have survived, but a high proportion of the Denisova 3 genome was intact.
