Charles Darwin wrote this seminal work that deals with the relationship between the environment, nature, evolution, the complete genera of species, and how nature selects via reproduction the most efficient beings to inhabit the future of that particular specie.

He established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.
