What will be an ideal response?
Mutations are the source of genetic change. Neutral or beneficial mutations may remain in a population even though they have not become prominent. At some point the need may arise, due to changes in the environment, to select a new trait. Mutations have provided a pool of possible alternatives. Natural selection will work on those traits by selecting for the one or ones that provide the best reproductive success, or in other words are the most "fit."
