Very good. Maybe add a bit on what the model ISN'T. "So one day a snake gives birth to a bird, but where is there another little bird for it to mate with?; When have you ever seen a rat turn into a human?" etc. One strawman has macro changes in one generation, the other in less than a single generation. That kind of thing.

I thought of that, but it was getting too long even without that stuff. I kinda decided to say what it IS, and deal with the goofy stuff another time. I donno. I'm still mulling it over.
