A mutation scenario that can lead to natural selection is when the mutation provides a selective advantage to an organism or a population in a particular environment. Organisms with the advantageous mutation are more likely to survive and reproduce, passing on their genes to their offspring. Over time, the frequency of the advantageous mutation will increase in the population, while the frequency of the original gene will decrease. Natural selection favors traits that increase an organism's fitness, or ability to survive and reproduce. Therefore, any mutation that results in an increased fitness and the ability to adapt to changing environments can lead to natural selection.
