On the Origin of Species or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life [3] is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology ; it was published on 24 November The book 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 collected on the Beagle expedition in the s and his subsequent findings from research, correspondence, and experimentation. Various evolutionary ideas had already been proposed to explain new findings in biology. There was growing support for such ideas among dissident anatomists and the general public, but during the first half of the 19th century the English scientific establishment was closely tied to the Church of England , while science was part of natural theology. Ideas about the transmutation of species were controversial as they conflicted with the beliefs that species were unchanging parts of a designed hierarchy and that humans were unique, unrelated to other animals.

Although in the Origin of Species, the derivation of any particular species is never discussed, yet I thought it best, in order that no honourable man should accuse me of concealing my views, to add that by the work in question 'light would be thrown on the origin of man and his history. Natural history. Chapter XI deals with evidence from biogeography , starting with the observation that differences in flora and fauna from separate regions cannot be explained by environmental differences alone; South America, Africa, and Australia all have regions with similar climates at similar latitudes, but those regions have very different plants and animals. The book produced a wide range of religious responses at a time of changing ideas and increasing secularisation. Darwin Online: On the Origin of Species , He had not completely avoided the topic: []. Retrieved 24 November Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring Reminded of his lack of expertise in taxonomy , Darwin began an eight-year study of barnacles , becoming the leading expert on their classification. In a May letter, Darwin mentioned a print run of 2, copies, but it is not clear if this referred to the first printing only, as there were four that year. Darwin expected species to change slowly, but not at the same rate — some organisms such as Lingula were unchanged since the earliest fossils. Darwin did not publish his own views on this until He notes that both A. He suggested that bees that make hexagonal cells evolved in steps from bees that made round cells, under pressure from natural selection to economise wax.

Georges Cuvier strongly disputed such ideas, holding that unrelated, fixed species showed similarities that reflected a design for functional needs. Charles Darwin. Carefully reasoned and well-documented in its arguments, the work offers coherent views of natural selection, adaptation, the struggle for existence, survival of the fittest, and other concepts that form the foundation of modern evolutionary theory. While some, like Spencer, used analogy from natural selection as an argument against government intervention in the economy to benefit the poor, others, including Alfred Russel Wallace , argued that action was needed to correct social and economic inequities to level the playing field before natural selection could improve humanity further. Darwin Online, p. Chapter XIII starts by observing that classification depends on species being grouped together in a Taxonomy , a multilevel system of groups and sub-groups based on varying degrees of resemblance. The text of Origin itself has been subject to much analysis including a variorum , detailing the changes made in every edition, first published in , [] and a concordance , an exhaustive external index published in Much of the chapter responds to George Jackson Mivart 's criticisms, including his claim that features such as baleen filters in whales, flatfish with both eyes on one side and the camouflage of stick insects could not have evolved through natural selection because intermediate stages would not have been adaptive. Darwin published his own explanation in the Descent of Man On 28 March Darwin wrote to Lyell asking about progress, and offering to give Murray assurances "that my Book is not more un -orthodox, than the subject makes inevitable. Why is not all nature in confusion, instead of the species being, as we see them, well defined?
