I observe that the finches on various islands have distinct beak shapes. This may indicate that these birds have adapted to their specific environments over time. The differences in beak shape could be due to the available food sources on each island, suggesting that natural selection is at play. The finches with beak shapes best suited for accessing their food sources would have greater reproductive success, leading to the evolution of these varied characteristics.
Upon arriving, you notice that finches found on different islands have different-shaped beaks.
Pretend you are Charles Darwin who has just landed on the Galapagos Islands. Describe your first observations and how they may relate to your evolutionary theories.
