Homo Neanderthalensis and Homo Denisovanensis were both descended from Homo Heidelbergensis, who shared a common ancestor with Homo Sapiens. The Neanderthals and Denisovans assimilated back in to Homo Sapien populations who came out of Africa. "Homo Sapien Sapiens" are just really more recent Homo Sapiens, and, depending on their ethnic phenotype, they have more or less Neanderthal or Denisovan DNA.
