"Species" is kind of a nebulous concept to some degree. There are different species that can produce fertile offspring, but just don't in the wild in practice because of geographic separation or some similar barrier.

But if they actually do, taxonomists are likely to call them subspecies. My impression about the Neanderthal revelations is that it's pushing people to go back to the classification of neandertalensis as a subspecies of H. sapiens.

And there are humans who will screw anything that moves. Probably always have been.
