It's not the only mechanism of evolution, though. If mutation existed without natural selection, evolution could not take place. They work hand in hand.

I believe if someone could prove the rate of positive mutations that are both beneficial and passed on they would learn that there has not been close to enough time to have all the variations we see of life on this planet. Even if this earth is 4.6 billion years old. I think they are saying it is even older now.
