The Selfish Gene Theory is the title of a text published by the zoologist and evolutionary biologist Richard Dawkins, which talks about the theory of evolution. This theory was formulated in 1976 through the dissemination of this text. In it you can see how the author tries to explain how genes really are and not people or species, which are chosen by nature.
Although this theory does not alter at all the already established concept of evolution, it does bring into consideration the principle of an idea that was understood and that was deeply examined (taking into account its pros and cons), by the scientific community, the which in certain aspects has rejected it and in others has accepted it.
Nowadays, when trying to explain evolution, it is impossible not to touch on the subject of genes. The theory formulated by Dawkins establishes that it is the genes that have originated a convenient response of an organism to its environment. This genetic contribution given to evolutionary theory was necessary to be able to explain certain physical and behavioral characteristics that were developed through previous works, such as that of the theory of species, shaped by Darwin. Here he said that only the fittest organism was the one that had the possibility of leaving offspring. However, the selfish gene theory says that only the fittest genes are responsible for a subject leaving offspring, something that is totally true.
Dawkins tries to redefine the concept of gene by qualifying it as a heritable unit, capable of generating one or more specific effects. These genes take advantage of organisms to be able to disperse among the population and thus be able to ensure their transitory prolongation beyond the individual.
Dawkins makes use of the rhetorical figure, in this case a metaphor, when he refers to selfish genes, trying to make the reader more easily assimilate the information, something that he was able to achieve since the theory was very popular with his audience, where most were not scientists
