Charles Darwin studied the finches in the galapagos islands and found that their beaks vary in shape and size. Darwin found that the finches that ate mostly insects had long, narrow beaks. Finches that ate seeds had shorter and broader beaks to crush seeds. Which statement below best describes how natural selection resulted in the four types of finches below.
A. The narrow beak finches came first and evolved into broad-beaked finches through a series of mutations.
B. The residents of the Galapagos islands selectively bred together finches having the traits they wanted them to have.
C. The broad-beaked finches wore down their beaks digging for insects and passed their narrower beak to their offspring.
D. Over time the finches that were born with beaks better suited to the available food supply in their habitats survived and reproduced.
