How Does Natural Selection Lead to Evolution?

Natural selection is a key mechanism in the process of evolution. It occurs when individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over time, this results in a population with a higher frequency of the advantageous traits, leading to evolutionary change. With the survival of the fittest, organisms that are best adapted to their environment will have more opportunities to pass on their genetic material. This process ultimately drives the gradual transformation of species over generations, leading to the diversity of life we see today.
