Explanation:
Detailed explanation-1: -Natural selection occurs when environmental pressures favor certain traits that are passed on to offspring. The “big prize” in natural selection is passing on genetic information. Natural selection acts on populations. Individuals do not evolve in genetic evolutionary terms.
Detailed explanation-2: -In generation after generation, advantageous traits help some individuals survive and reproduce. And these traits are passed on to greater and greater numbers of offspring. After just a few generations or after thousands, depending on the circumstances, such traits become common in the population.
