How are shapeshifters and vampires NOT human? Shapeshifter routinely breed with women (so much so that the unphased ones are not called as such), vampires are turned humans, and occasionally manage to breed themselves again with women. They're all humans allright, without unduly stretching the definition.

Now, if Edward an Jacob managed to breed with each other, THAT would really shake the whole edifice...
