Research by Rosemary and Peter Grant sheds new light on Darwin's finches. Their study of finch populations on the Galápagos Islands demonstrates that evolutionary changes in beak size and shape occur very rapidly in response to severe environmental changes. In the museum exhibit, visitors take beak measurements of Galápagos finches and learn how the selective effects of environmental change, acting through the abundance of different food types, influence variation in finch beaks.
