Is having a genetic advantage enough for evolution to occur? Doesnt a organism require some sort of knowledge (or instinct) in order to use such an advantage in order for it to be any sort of advantage? Example: we say the first step in the formation of a eye is a cell that is sensitive to light. Well wouldnt the organism with this advantage have to be aware of it in order to use it. It cannot be taught how to use it as there wouldnt be no any one to teach it. Without and knowledge or instinct of how to use this new trait, this organism would have no advantage at all. A organism with the ability to sense light means nothing if it does not know how to apply it. If you don't know how to use it you lose it.
