How or finches in the Galapagos islands good example of adaptation?

The finches of the Galápagos Islands, famously studied by Charles Darwin, exemplify adaptation through their diverse beak shapes and sizes, which evolved in response to varying food sources on the different islands. For instance, some finches developed larger, stronger beaks to crack open hard seeds, while others evolved narrower beaks to capture insects. This adaptive radiation allows them to exploit different ecological niches, showcasing natural selection in action. Their variations illustrate how species can evolve traits that enhance survival and reproduction in specific environments.
