How are finches in the galapagos islands a good example of adaptaition?

Finches in the Galápagos Islands are a prime example of adaptation due to their diverse beak shapes and sizes, which evolved in response to the varying types of available food sources on different islands. For instance, some finches developed larger, stronger beaks to crack open tough seeds, while others adapted with slender beaks to extract insects from crevices. This variation illustrates Darwin's theory of natural selection, as those better suited to their environment were more likely to survive and reproduce. Consequently, these adaptations contributed to the finches' speciation across the archipelago.
