The beaks of finches on the Galapagos Islands enlarged over generations in response to variations in food sources. Larger beaks were favored for cracking tougher seeds during periods of drought when softer seeds were scarce. This adaptation allowed finches with larger beaks to better survive and reproduce, passing on their genes for larger beaks to the next generation.
