What is Impossible in Evolution?

Season 9 Episode 3 | 19m 29s | Video has closed captioning.

Could humans ever evolve to have wings? Why don’t fish have propellers? Why don’t tigers have wheels? Why don’t zebras have laser turrets? These might all seem like stupid questions (and maybe they are!) but they can teach us a lot about how evolution actually works, and how it doesn’t work.
