The Evolution of Improved Fitness Introduction he theory of evolution includes a number of ideas that some people find difficult to accept intuitively. One of the most difficult seems to be the notion that the intricate and interdependent structures we observe in modern plants and animals arose through random genetic mutations selected over time. For some people it is much easier to believe that the beautiful and functional features of the human eye, for example, were designed by an intelligent creator than to imagine how they could have been generated through random events. Creationists capitalize on this conceptual difficulty, presenting several arguments that appear to demonstrate that random mechanisms could never lead to even a single functioning protein, let alone an eye. These arguments can be refuted by theoretical counter-arguments; yet many people have difficulty accepting these counter-arguments at an intuitive level. What might be persuasive would be a clear example in living organisms that shows how random mutation plus selection can lead to
