|aMost iguanas in the Galápagos Islands live and eat on land, but one species does something no other iguana does anywhere in the world -- it launches itself into the sea and dives underwater to feed. Descended from a common ancestor and living within sight of one another, the author offers a theory how did land and marine iguanas develop such different appearances and lifestyles.--|cSource other than Library of Congress.
