The Grants verified Darwin's theory of natural selection by making observations over a long period of time. They studied a population of finches on the Galápagos Islands for over 30 years, documenting changes in beak morphology and other characteristics that were related to environmental changes and selective pressures. Their research provided strong evidence for the role of natural selection in driving evolution.
