On the Origin of Species (or more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favored Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle-expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.
Summary:- When Charles Darwin published The Origin of Species 150 years ago, he deliberately avoided the subject of the origin of life. This, coupled with the mention of the 'Creator' in the last paragraph of the book, led us to believe he was not willing to commit on the matter. An international team now refutes that idea and shows that the British naturalist did explain in other documents how our first ancestors could have come into being.
