Charles Darwin's On the Origin of Species Celebrates 150 Years

On the Origin of Species, published on 24 November 1859, is a seminal scientific work, considered to be the foundation of evolutionary biology. Darwin's book introduced the 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.

Though, Darwin's book did not address directly the question of human evolution, saying only that "Light will be thrown on the origin of man and his history", the possibility of linking humans with earlier apes by descent became clear after 1859 with the publication of On the Origin of Species which argued for the idea of the evolution of new species from earlier ones.

At the time, ideas about the transmutation of species were controversial as they conflicted with scientific mainstream and religious beliefs that species were unchanging parts of a designed hierarchy and that humans were unique, unrelated to animals. As a result, Darwin's evolution theories were met with ridicule by the scientific community and hostility by the Church before moving to the front line of science.
