y'all know about tetronomes(y'know the kinda tumors that can grow eyes, teeth, nerves, organs, etc), well if they can do that, and someone gets one, if under the right(or wrong) circumstances it gets cut out in a weird way, it can still grow and become a seperate entity, and if it was able to reproduce solo, then it could cause the creation of a whole new species of animal(s) that'll probably evolve to adapt to our environment and surroundings, process that for a moment, the chances of that happening are ridicoulsly low, but never zero....
