The correct answer is "Natural selection leads to evolution."
Natural selection is a process by which certain traits become more or less common in a population over time. It occurs because some individuals have advantageous traits that help them survive and reproduce better than others. These advantageous traits are passed down to their offspring, making them more likely to survive and reproduce as well. As a result, over many generations, the frequency of advantageous traits increases in the population, leading to evolution.
Evolution, on the other hand, is the change in the inherited characteristics of a population over time. It can occur through various mechanisms, including natural selection, genetic drift, mutation, and gene flow. However, natural selection is the most widely recognized and studied mechanism of evolution because it can lead to the adaptation of organisms to their environment and the emergence of new species
