Scenario 3: In the Galapagos islands, a community of plants produced large tough seeds and small soft seeds. Most members of a population of finches are found to have small beaks, while a smaller portion of the group have large beaks. The islands experienced a drought that negatively impacted the community of plants that produced small soft seeds, leaving the island with plants that produced large tough seeds. After the drought, it was observed that the finches with smaller beaks were reduced, and the majority of finches were found to have large beaks.
