Genetic variation (population has variations within it), Overproduction of offspring (more offspring are produced than survive), Struggle for existence (some variations are favorable), and differential survival & reproduction ( those that survive have favorable traits which they pass on. Natural selection, Darwin argued, was an inevitable outcome of three principles that operated in nature. First, most characteristics of organisms are inherited, or passed from parent to offspring, although how traits were inherited was unknown. Second, more offspring are produced than are able to survive.Natural selection is the way by which nature selects suitable and the fittest organism for evolution.

There are two major components to the theory. The first is the mechanism of natural selection, which was proposed independently by Charles Darwin and Alfred Russell Wallace in 1858. Abstract. In his qualitative theory of natural selection, Darwin (1859) proved that selection is able to produce adaptive heritable changes in populations. His qualitative reasoning, however, did not satisfy the founders of theoretical population genetics. Their major task was to establish a quantitative theory which could derive the rates of ...Components of Natural Selection. 1) Variation- individuals in a population differ from one another 2) Inheritance- some of these differences are inherited by offspring from their parents 3) Differential reproductive success- individuals with certain traits are more successful than others at surviving and reproducing in their environment.What is natural selection?
