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 finches in the Galápagos Islands, monitoring changes in beak size and shape among different finch populations in response to varying environmental conditions, which provided empirical evidence supporting natural selection.
