Peter and Rosemary Grant

Peter and Rosemary Grant are renowned evolutionary biologists who studied finches on the Galápagos Islands. Over decades, they observed how finch populations adapt their beak sizes and shapes in response to changes in the environment, like food availability. Their work provides clear evidence of natural selection in action, demonstrating how species evolve over relatively short periods. Their research has significantly advanced our understanding of evolutionary processes and the dynamic relationship between organisms and their habitats.
