That biological heritage could be interesting, but it'll have to be brought convicning and quite detailed. You'd almost need a fairly big flashback to the origin of ghouls where we relive the past to get to know how they surfaced on our planet. I doubt that's going to happen, what's more. Tokyo Ghoul isn't that much about 'ghoul' itself, but more about the characters living in the group of either ghoul or human. It's the psychology, more then the history. They can go together, but there first needs to be a crucial point where it's clear history is a big part of what can solve the issue, which is not yet the case.
