Another source for mutations are the copies of DNA
men make. Women have X number of eggs, and they are produced very early on while in the womb. Biology gets it right to a high degree at this stage. Men make gazillions of copies throughout their life so by the sheer numbers some errors are made. Cosmic rays and radition from minerals are very important to supply the random chance of mutation.In my study of science I can't help miss how important random chance is. Mutation is a good example. When I look beyond a single random event
to a bigger picture order does come out of randomness. At the moment of the big bang when
our universe winked into existance it was lucky there was exactually the right amount of energy and matter so our universe did not explode or implode in a wink. The frequency at which every atom vibrates was set at the instant of creation, had it been slightly different we could of gotten space but no time of vise versa; out physical laws whould of been very different. Reality is not an illusion but level in Quantum Mechanics.Please take this only as my view, I realize that no one's view can hope to answer all the questions. I think it is more important to find what works for you and allow others to do the same.
