Chаnging the rаinfаll has a significant effect оn the beak size оf the island's finches. Little rainfall, causes the small seeds оn the island to die out. This leaves the large seeds as the main food source. This allows birds with large beaks to break open these seeds, eat them, and live long enough to have children who may inherit the large beak trait. Since finches with large beaks are able to eat large seeds, they will have an advantage in this environment. Over time, the population will have more finches with large beaks. Select which graph represents the change in beak size of finches after 100 generations of drought. The dotted line represents the finch population in the first generation. The solid line represents the finch population after 100 generations.
