Natural selection is a process by which organisms get adapted to their environment. This adaptation is based on the selective reproductive changes in the genetic material. Those changes in the genotype that increase the probability of survival of organisms are preserved and are transferred to the next generations. The evolution of species is brought about by the consequences of this process.
The differences in the survival, in the process of fertility, in the developmental rate, in the success of mating, and in any other life cycle aspect all give rise to the process of natural selection. These differences that lead to natural selection have a definite effect on the number of progenies left by an organism. Moreover, natural selection increases the beneficial changes and eliminates those that are harmful.
