I know. I said that. I said background radiation (not just cosmic rays, but also natural radioactive decay) is responsible for a large part of the naturally-occurring mutations that drive evolution. Some also occur due to DNA transcription errors and other reproductive variables.

Actually, some of it is. If you turn the brightness and contrast all the way down, you'll still occasionally see bright speckles. About 1% or so of those are due to cosmic rays, IIRC. You can't tell which ones, though.
