Question

Quizplus · Accepted Answer

During prolonged drought, the availability of food decreases, leading to competition for resources. Finches with deeper and stronger beaks have an advantage in accessing the remaining food sources, increasing their chances of survival. Therefore, the survival of each bird was strongly influenced by the depth and strength of its beak as the drought persisted.
