Can you recommend any good books about genetics and natural selection to people who don't have a biology background? I can handle some math, but I just break software for a living and I don't know biology.

Sorry for the sidetrack, but thanks for posting this. I've always wondered about some of the higher order implications of natural selection, and ants are a great example. Like how megacolonies take in ants from other places, that's so crazy because it doesn't make sense once you're looking at a small enough perspective but makes perfect sense at a larger scale. Bees are cool too.
