Writing to her fellow Malthusian (and atheist) George Holyoake she enthused, "What a book it is! – overthrowing (if true) revealed Religion on the one hand, & Natural (as far as Final Causes & Design are concerned) on the other. The range & mass of knowledge take away one's breath." To Fanny Wedgwood she wrote, "I rather regret that C.D. went out of his way two or three times to speak of "The Creator" in the popular sense of the First Cause.... His subject is the 'Origin of Species' & not the origin of Organisation; & it seems a needless mischief to have opened the latter speculation at all – There now! I have delivered my mind."
Title: On the Origin of Species
Content:  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), published on 24 November 1859, is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. 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 1830s and his subsequent findings from research, correspondence, and experimentation. Various evolutionary ideas had already been proposed to explain 
Title: Genetics and the Origin of Species
Content:  Genetics and the Origin of Species is a 1937 book by the Ukrainian-American evolutionary biologist Theodosius Dobzhansky. It is regarded as one of the most important works of the modern synthesis, and was one of the earliest. The book popularized the work of population genetics to other biologists, and influenced their appreciation for the genetic basis of evolution. In his book, Dobzhansky applied the theoretical work of Sewall Wright (1889–1988) to the study of natural populations, allowing him to address evolutionary problems in a novel way during his time. Dobzhansky implements theories of mutation, natural selection, and speciation throughout his book to explain habits of populations and the resulting effects on their genetic behavior. The book explains evolution in depth as a process over time that accounts for the diversity of all life on Earth. The study of evolution was present, but greatly neglected at the time. Dobzhansky illustrates that evolution regarding the origin and nature of species during this time in history was deemed mysterious, but had expanding potential for progress to be made in its field.

During Darwin's lifetime the book went through six editions, with cumulative changes and revisions to deal with counter-arguments raised. The third edition came out in 1861, with a number of sentences rewritten or added and an introductory appendix, An Historical Sketch of the Recent Progress of Opinion on the Origin of Species, while the fourth in 1866 had further revisions. The fifth edition, published on 10 February 1869, incorporated more changes and for the first time included the phrase "survival of the fittest", which had been coined by the philosopher Herbert Spencer in his Principles of Biology (1864). In January 1871, George Jackson Mivart's On the Genesis of Species listed detailed arguments against natural selection, and claimed it

Content:  On the Origin of Species was first published on 24 November 1859, priced at fifteen shillings. The book had been offered to booksellers at Murray's autumn sale on 22 November, and all available copies had been taken up immediately. In total, 1,250 copies were printed but after deducting presentation and review copies, and five for Stationers' Hall copyright, 1,192 copies were available for sale. Significantly, 500 were taken by Mudie's Library, ensuring that the book would be widely circulated. By then the novelist Charles Kingsley, a Christian socialist country rector, had sent Darwin a letter of praise (dated 18 November) regarding the presentation copy he had received: it was "just as noble a conception of Deity, to believe that He created primal forms capable of self development...as to believe that He required a fresh act of intervention to supply the lacunas which He Himself had made." In the second edition Darwin added these lines to the last chapter, with attribution to "a celebrated author and divine". See the Reactions to On the Origin of Species for developments following publication, in the context of his life, work and outside influences at the time.

They celebrated the ideas which "over the last 150 years have revolutionised our understanding of nature and our place within it". In a survey conducted by a group of academic booksellers, publishers and librarians in advance of Academic Book Week in the United Kingdom, On the Origin of Species was voted the most influential academic book ever written. It was hailed as "the supreme demonstration of why academic books matter" and "a book which has changed the way we think about everything".
