If you accept evolution as your source of existence and foundation. You find you don't really have a choice or a free will. Then the court system would be pretty silly. Everyone could just say, it's because of evolution that I did this or that I have no will of my own. It's just silly.

O'nus there is also a group of people that believe bigfoot is your father. There are some holes in this theory but they are still working on it. Further investigation and inquiry is needed. Or maybe it's an insane theory.
