On the Origin of Species (Sixth edition)

The sixth and final edition of Charles Darwin's groundbreaking work that introduced the theory of evolution by means of natural selection.

First published in 1859, Charles Darwin'sOn the Origin ofSpecies introduced the scientific theory of evolution by means of natural selection, a revolutionary idea at the time. Fiercely debated on its release, Darwin's famous work was revised several times over the following decade, partly to refute the scientific and religious objections of the author's contemporaries. In this sixth edition ofOn the Origin of Species, Darwin lays out his theory by citing his studies done in the Galpagos aboard the HMSBeaglein the 1830s, as well as his follow-up research over the ensuing two decades.
