Most scientists think that a small group of finches colonized the Galápagos Islands thousands of years ago. They would have been the only seed-eating birds on the islands. Suppose one island was very dry and another had plentiful rainfall. What might happen to the finch populations after millions of years? Demonstrate an understanding of evolutionary processes (such as directional selection, stabilizing selection, disruptive selection, sexual selection, gene flow, genetic drift) and variation, heritability, reproductive advantage to natural selection.

Evolutionary adaptations

Evolutionary adaptation is the process through which organisms adapt or adjust to their surroundings to increase the chances of survival, mating, and reproduction. An organism's behavior, physiology, and structure are adjusted or changed to make it more suited to its environment.
