Drs. Peter and Mary Grant verified Darwin’s theory of natural selection by making observations over a long period of time. They conducted extensive research on Darwin's finches in the Galápagos Islands, observing how variations in beak size and shape corresponded to changes in food availability, demonstrating natural selection in action.
