^ You're right about the species thing, I wasn't clear enough. I meant that they're genetically distinct organisms, despite their ability to cross-breed (which, as we've seen, is extremely difficult).

Well, myostatin-related musclar hypertrophy is a condition caused by a genetic mutation (not classified as a disease, though), and I mentioned earlier that it seems very likely Ghouls branched off from humans, but we're talking about a separate genome, not a single gene mutation.

And the RC Cells can't fundamentally be an illness because everyone in the world has them, ghoul and human. You only experience the negative effects of them in your body if you develop ROS, but that's really just a form of cancer, and very rare.

The weird thing about them is shown in the Qs situation, where even though they have a kakuhou, there's a threshold where one can have a good portion of a ghouls powers, but still function as a human. It seems like the course of evolution would pick that route, not just leap to a sudden cannibalizing apex predator.
