Quizplus · Accepted Answer

Drought conditions caused a scarcity of small, soft seeds, which were the primary food source for Geospiza fortis with smaller beaks. Therefore, birds with larger beaks had higher fitness, as they were able to eat larger and harder seeds that were still available, and were better able to survive and reproduce. This resulted in a change in the population in which the next generation had larger beaks than the previous one.
