Natural Selection in Nature
Land and marine iguanans on The Galapagos Islands also differ. Marine Iguanas, pictured above, are darker and more social than light-colored, territorial Land Iguanas,
Darwin also studied the Galapagos finches. These birds have different types of beaks, depending on their diet. This Medium Ground-Finch uses its large beak to crush seeds.
