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 field studies on finches in the Galápagos Islands, documenting changes in beak size and shape in response to environmental changes, which provided concrete evidence for natural selection in action.
