Evolution

My question concerns evolution. In your book you made the statement of how a cell “knows” what it will become without any evidence of how it knows this. You state something to the effect that this is because God tells it what it will be (bad paraphrase but you get my meaning). I was wondering if this applies to evolution also. I always wondered how does a cheetah know to make its fur yellow and black? How does an organism know to make an eye to see the world? Survival of the fittest cannot explain this because the chance of something randomly making an eyeball to see the world would seem slim.
