Answer:

Darwin noticed that fruit-eating finches had parrot-like beaks, and that finches that ate insects had narrow, prying beaks Later, Darwin concluded that several birds from one species of finch had probably been blown by storm or otherwise separated to each of the islands from one island or from the mainland.

A
It is directional selection since there is a loss of medium sized nuts it allows more birds with small or large beaks to thrive
