Final answer:
Human-induced selection regimes in natural populations highlight scenarios like hunting that alter species' traits over time. Hunting is an example of an anthropogenic impact leading to evolutionary changes, as opposed to natural events or conscious selective breeding. Option b is answer
Step-by-step explanation:
An example of human-induced selection regimes in natural populations would be hunting. This practice can lead to directional selection, whereby certain traits become more prevalent in a population because they offer a survival advantage in an environment changed by human activities.
For instance, if hunters preferentially target large deer, over time the deer population may evolve to be smaller on average. Unlike global warming, volcanic eruptions, and plate tectonics, which are not directly caused by human activities, hunting can cause a shift in the population's genetic variance toward traits that confer a higher survival rate under hunting pressure. Option b is answer
