This isn’t evolution, but it’s too amazing not to post. It’s a movie of an entire rotation of Jupiter, made over several hours by Damian Peach in Barbados. (Jupiter, huge as it is, rotates on its axis in a bit less than ten Earth hours.) I found this at Bad Astronomy, where Phil Plait gives the details. Peach’s website has even more photos and information.
