My theory is that ghouls evolved as a natural predator, people started starving so they ate what they could, humans, a few developed a taste for it, after generations of eating nothing but humans their digestive system is irreversibly changed through fighting with out ghouls and hunting humans they evolved a organ/weapon to help them.

They probably started with low number but as the human population grew so did theirs, humans fought back the ones that weren't as strong and fast were killed by humans and so the ghouls passed on their stronger genetics until it became a common trait of ghouls.
