Which of the following is NOT a characteristic of natural selection?

Natural selection is a fundamental mechanism of evolution that drives the adaptation of organisms to their environments over long periods. The correct response reflects the understanding that natural selection typically occurs over extended timescales rather than short periods.

The process of natural selection favors traits that enhance reproductive success, which means that organisms with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation. This gradual shift in traits across generations contributes to the adaptation of species to their environments.

Additionally, competition for limited resources is an essential component of natural selection, as organisms must compete for food, shelter, and mates. This competition can lead to the survival of the fittest, where only those best adapted to their environment thrive.

In summary, the characteristic that states natural selection occurs over short periods is not accurate; true natural selection unfolds over many generations, allowing species to evolve in response to changes in their environment.
