The larvae of butterflies eat the leaves of flowering plants. Many of these larvae are eaten by birds before they can become adult butterflies. In one butterfly population, most larvae eat leaves continuously and ignore other organisms around the leaves. But a few newly hatched larvae stop moving when a shadow suddenly falls on the leaves. In a few years, most of the larvae in this population stop moving when they detect a sudden shadow. b. Write a short paragraph describing the process that occurred in this butterfly population. Use the terms genetic variation, allele frequency, and natural selection in your answer.
