Answer 1

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 the Galápagos finches, studying changes in beak size and shape in response to environmental changes, which provided concrete evidence for natural selection in action.
