Question
select the correct answer. an organism was hunted almost to extinction, but the population bounced back. which evolutionary change did this species most likely experience? a. bottleneck effect b. migration c. mutation d. sexual reproduction e. disruptive selection
The bottleneck effect occurs when a population is drastically reduced in size (like being hunted almost to extinction) and then rebounds. This event can lead to genetic drift as the small surviving population may not represent the original genetic diversity. Migration involves movement of individuals, mutation is a change in DNA, sexual reproduction is about how offspring are produced, and disruptive selection is a type of natural selection—none of these match the scenario of a population being nearly wiped out and then recovering. So the correct answer is related to the bottleneck effect.
