What is the Meaning & Definition of theory of Darwin

Charles Robert Darwin was one of the scientists and naturalists most notable in the history of English origin, Darwin, would shake the world of science in the nineteenth century with his theory of natural selection which postulated that all living species of planet Earth have managed to evolve over time and an ancestor shared by a process called just as natural selection. So that natural selection was the great proposal of Darwin when it comes to an explanation about biological evolution.
According to the work of Darwin natural selection is a phenomenon typical of the evolution which has a character of general law and consists of the differential reproduction of the information Genetics (in the form of DNA) of a biological community. Meanwhile, natural selection has to present in a given natural environment conditions help, or failing that complicate, the reproduction of the organisms.
Now, Darwin, enunciated the need for the existence of three conditions: the feature or property subject to the selection should be plausible of inheritance; must have variability of the trait among the beings of a population; and this variability must give way to differences in survival or reproductive success, creating what some new features may spread in the population. Meanwhile, the accumulation of all the changes across generations is what will produce the phenomenon of evolution.
In the work written by Darwin and titled the origin of species, published in the year 1859, is left seated in a forceful way that we mentioned lines above with regard to that if there are variations in the reproduction of the organisms and the environment does not accept a population in development agencies, those that have features little adapted tend to die , while those who have secure good adaptation features that will survive.
Repetition over time indicated by Darwin schema consists of the evolution of species.
