Answer

Brief Explanation:

Natural selection favors traits that increase survival and reproduction. Since birds with short and long beaks can eat seeds that medium - beaked birds can't, over time, the frequency of short and long beak lengths may increase, shifting the average beak length. The original average is in the middle (medium - beaked). As natural selection acts, the new average will shift towards the more favored short and long beak lengths.
