How did some of the Galapagos finch species, which traditionally were seed eaters, evolved over generations to prefer insects over seed?
Darwin observed that the Galapagos species differed from each other in beak size and shape. He also noted that the beak varieties were associated with diets based on different foods. He concluded that when the original South American finches reached the islands, they dispersed to different environments where they had to adapt to different conditions. Over many generations, they changed anatomically in ways that allowed them to get enough food from insects and survive to reproduce. ChaCha!
