The theory of evolution predicts sustained beneficial changes in life forms based on random crap (radiation, bad DNA transcription, etc) and reactions to the environment, among others. Beneficial changes don't always spread to the entire population and lifeforms with these traits will simply die out, but there have been enough observed occurrences of this to provide evidence for this theory (Darwin and the finches, and how each different finch fed itself from different, non-competing parts of the eco-system, or the brown/white moth study in industrial England, etc) There's a lot more that real biological scientists can get into, but my field isn't biology. There should be quite a bit available even from just googling.
