I agree, there's a difference, I would think, between "Natural Selection" and "Evolution".

Here's something they don't say about this particular Butterfly - The little beggars are carnivorous! I'm an avid cyclist. You'll see a cloud of these things hovering over road-kill that's starting to decompose. As you get closer, you'll see that the cat, rat, whatever, is covered with these butterflies. Has anyone else here ever seen anything like that?
