Addendum(b)
In part, an explanation/translation: Thought of human/reptile connection via the most primitive (or oldest) parts of our brains- which made me think of Adam Sandler's Waterboy- and his argument with Colonel Sanders about the medulla oblongata. Waterboy said something like, "Mama says that alligators are so ornery cuz they have all them teeth and no toothbrushes." The Professor had said the aggressiveness is due to their large medulla oblongatas.
