Charles Darwin said evolution was too slow to be observed, but modern studies have corrected this assertion. The Grants discussed their decades of work studying Darwin’s finches on the Galápagos Island of Daphne Major, as chronicled in the Pulitzer Prize-winning book The Beak of the Finch: A Story of Evolution in Our Time. Their research showed that Darwin’s finches evolve repeatedly when the environment changes. They have even observed the initial stages of new species formation!
