Final answer:

Darwin's finches exhibit different beak shapes that are specialized for obtaining specific food sources, showcasing natural selection.


Explanation:

The main difference between Darwin's finches was the size and shape of their beaks. Darwin observed that different beak shapes among finch species were adaptations to acquire various food sources, supporting his theory of natural selection.
