Answer:

Charles Darwin was fascinated by the finches on the Galapagos Islands. He noticed that the finches with long, narrow beaks were able to eat bugs, while other finches that had shorter and thicker beaks were able to crush and eat nuts. Darwin suggested that these different species of finches must have from a single species of finch that came to the islands a long time ago. When the single species of finch experienced breeding, some of the small changes in beak shape and size may have turned into an trait that would help that finch give birth and pass on the trait to its offspring.
