Go rest high on your mountain.
I don't see how evolution is driven by random mutation. I can see how it is moved forward by an organism adapting to its environment through physiological changes brought about by a biofeedback system which seeks to make it as energy efficient as possible in its new environment. Notice how organisms which live in unchanged environments are almost identical to their ancestors from millions of years ago, while organisms in more dynamic environments have changed quite a bit. If it were simply random mutations, then the species in non changing environments should still be acquiring the same level of changes over time as their more challenged neighbors. Evolution is powered by physiological adaptation and not random mutation IMO.
