on the origin of species by means of natural selection

The scientific theory of evolution has itself evolved since Darwin first presented it, but natural selection remains the most widely accepted scientific model of how species evolve. The book was controversial, and generated much discussion on scientific, philosophical, and religious grounds.

Hence the book that appeared after the Origin was, to everyone’s surprise, The Various Contrivances by which British and Foreign Orchids are Fertilised by Insects (1862).

It introduced the theory that populations evolve over the course of generations through a process of natural selection. He would take seemingly intractable subjectslike orchids flowersand make them test cases for natural selection. He said that the mechanism in charge of directing evolution was natural selection. The book's full title is On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. He argued that species were not created, but rather evolved. The Origin of Species is a seminal work in scientific literature and arguably the pivotal work in evolutionary biology. This classic work of scientific literature, presenting the theory of evolution by means of natural selection, is still both relevant and controversial in the twenty-first century.
