  5. Finch Evolution • Their beaks have evolved over time to be best suited to their function. • Finches who eat grubs have a thin extended beak to poke into holes in the ground and extract the grubs. • Finches who eat buds and fruit would be less successful at doing this, while their claw-like beaks can grind down their food and thus give them a selective advantage in circumstances where buds are the only reliable food source. • Darwin's finches are an excellent example of the way in which species have evolved in response to their environments.
