Couple of wide ranging topics, herein. I had Dr. Seuss's classic "Go Cat Go!" on my mind, and this is the exact opposite, done in model trains. The chick at the end credits is an artist's conception of what a Neanderthal beauty queen might have looked like, as a means to explain how Neanderthals and Homo Sapiens got together. (In case you didn't get the memo, we all got about 2% Neanderthal DNA. That's a lot). I ponder at how we all went from hand axes to model trains in the course of time. Or moon landers, or whatever other yardstick you want to use.
