What did Charles Darwin observe about finches in the Galápagos Islands that was critical to the development of his theory of natural selection?

• All finches on the islands were identical.

• Finches on different islands had different types of beaks, suited to their specific diets.

• Finches changed the color of their feathers depending on the season.

• All finches on the islands ate the same type of food.
