... island have distinct habitats, diets, and behaviors, but the mechanisms involved in speciation continue to operate. A single year of drought on the islands can drive evolutionary changes in the finches. Drought diminishes supplies of easily cracked nuts but permits the survival of plants that produce larger, tougher nuts. Droughts thus favor birds with strong, wide beaks that can break these tougher seeds, ... producing populations of birds with these traits. It has been estimated that if droughts occur about once every 10 years ... disguising coloration), the organisms carrying that ge...
