But if it is truly a mutation, then there wouldn't be just one person with one set of animal traits. You would end up with a guy with one bunny ear and horns sticking out his forehead. Maybe have one guy with a fox head and body, but human limbs. The Faunus seem to have clean cut genetics, like instead of blue eyes they get bunny ears. That is why I think they are a species; not because it is easier to think that, but because the species itself seems way too clean to be the result of a mutation or some other kind of outside factor.
