Finches are birds that come in many different varieties and fill many different niches within an ecosystem. The beak of a finch is specialized to complement its niche. The ground finch lives on a tropical island and uses its beak to gather and crack open nuts. Over time, as the climate of the island changes, trees start producing nuts that have thicker, harder shells. As this change occurs in the nuts, which change in the finches may be observed in future generations?
