Does radiation aid evolution?
Radiation is often considered harmful for us on a personal level, but could it be beneficial for human kind because it will speedup genetic mutation and therefore, our development in general?
Mark D. - An interesting question and a philosophical question. I'm not sure we've been made to evolve that quickly. Radiation plays a very important role in treatment and especially in the treatment of some cancers, but I'm not sure that would be a very effective way for us to try and evolve.
Chris - It's reassuring. I'll avoid Chernobyl in the future then!
