All of your premises are based on faulty facts. You see, Charles Darwin was sailing on the Mayflower while Walt Disney was teaching alchemy to Captain Kirk, at which point humans realized or failed to realize they could evolve, revolve, devolve, unvolve or dissolve, and vice versa. The necessarily unnecessary need of necessities was unnecessarily re-necessitated, gerbils were subject to prosecution, light was invented, then the Germans bombed Atlantis. And, well, you can fill in the blanks, the rest is pretty obvious.
