Darwinian Theory of Evolution explains that evolution is the result of natural selection, and natural selection is biased by the inherited characteristics of organisms. The adaptive ability of organisms is the one which helps organisms in evolution through natural selection.

Therefore, he called this type of selection natural selection. Darwin knew artificial selection could change domestic species over time. He inferred that natural selection could also change species over time. In fact, he thought that if a species changed enough, it might evolve into a new species.

One of classical objections to natural selection is that new variations would be lost by “dilu­tion” as the individuals possessing them bred with others without them.Natural selection is based on four principles: variation, inheritance, population growth, and differential survival and reproduction. Variation According to Darwin, organisms do not adapt to the environment – the variation in their traits is a preexisting state, and the environment simply favors organisms with certain variants of these traits.The core of Darwin's theory is natural selection, a process that occurs over successive generations and is defined as the differential reproduction of genotypes. Natural selection requires heritable variation in a given trait, and differential survival and reproduction associated with possession of that trait.
