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.
Darwin's theory of evolution is based on key facts and the inferences drawn from them, which biologist Ernst Mayr summarised as follows: [6] Every species is fertile enough that if all offspring survived to reproduce, the population would grow (fact). Despite periodic fluctuations, populations remain roughly the same size (fact).
Darwin's first sketch of an evolutionary tree from his First Notebook on Transmutation of Species (1837). Charles Darwin became a naturalist at a point in the history of evolutionary thought when theories of Transmutation were being developed to explain discrepancies in the established faith based explanations of species.
In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859). Darwin's theory, originally called descent with modification is known contemporarily as Darwinism or Darwinian theory.
William Buckland subsequently recommended Darwin's paper for publication, praising it as "a new & important theory to explain Phenomena of universal occurrence on the surface of the Earth – in fact a new Geological Power", while rightly rejecting Darwin's suggestion that chalkland could have been formed in a similar way.

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species. [ 17 ] [ 18 ] By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact .
Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years. And, it may prove Charles Darwin's Theory of Evolution. A ...
The publication of Darwin's theory brought into the open Charles Darwin's theory of evolution through natural selection, the culmination of more than twenty years of work. Thoughts on the possibility of transmutation of species which he recorded in 1836 towards the end of his five-year voyage on the Beagle were followed on his return by ...
