An organism was hunted almost to extinction, but the population bounced back. Which evolutionary change did this species most likely experience?

bottleneck effect

migration

mutation

sexual reproduction

disruptive selection

The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful, which rarely represents the actual genetic makeup of the initial population. This leaves smaller variation among the surviving individuals.

It's disruptive selection, because the process of natural selection was disrupted by the hunting.
