Admit it. You've always wondered about cicadas

Why do 13- and 17-year cicadas live on those cycles? Wired Science today tells all. Yes, 13 and 17 are both prime numbers, and that could be part of the story. Very interesting. Did a divine hand do it or did the cicadas evolve that way? (Or was it ... both???)
