Quizplus · Accepted Answer

The concept of natural selection refers to the process by which more adaptive variants of an organism become more common in a population, while less adaptive variants become less common or even go extinct. This occurs because the more adaptive variants have genetic traits that make them better suited to survive and reproduce in their environment, allowing them to pass on those traits to their offspring. Over time, this can lead to significant changes in the traits of a population and even the evolution of new species.
