Charles Darwin in 1868. Darwinism is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Charles Robert Darwin (/ ˈ d ɑːr w ɪ n / [5] DAR-win; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, [6] widely known for his contributions to evolutionary biology.
Charles Darwin's grandfather Erasmus Darwin outlined a hypothesis of transmutation of species in the 1790s, and French naturalist Jean-Baptiste Lamarck published a more developed theory in 1809. Both envisaged that spontaneous generation produced simple forms of life that progressively developed greater complexity, adapting to the environment ...
The term was originally coined by Charles Darwin in an 1871 letter to his friend Joseph Dalton Hooker. [ 1 ] [ 2 ] This idea is related to later work such as the Oparin-Haldane hypothesis and the Miller–Urey experiment , which respectively provided a hypothesis for life’s origin from a primordial soup of organics [ 3 ] and a proof of ...
Darwin used various methods of enquiry: usually setting up rigorous controlled experiments which are clearly explained in the text, reporting the results and then drawing general conclusions. Studies of nyctinasty were particularly burdensome, to Darwin's rest as well as to the plants:
Darwin published a detailed account of his evidence and conclusions in On the Origin of Species in 1859. In the 3rd edition of 1861 Darwin acknowledged that others—like William Charles Wells in 1813, and Patrick Matthew in 1831—had proposed similar ideas, but had neither developed them nor presented them in notable scientific publications.

Following the inception of Charles Darwin's theory of natural selection in 1838, the development of Darwin's theory to explain the "mystery of mysteries" of how new species originated was his "prime hobby" in the background to his main occupation of publishing the scientific results of the Beagle voyage.
