Title: Charles Darwin
Content:  Darwin was a prolific writer. Even without publication of his works on evolution, he would have had a considerable reputation as the author of The Voyage of the Beagle, as a geologist who had published extensively on South America and had solved the puzzle of the formation of coral atolls, and as a biologist who had published the definitive work on barnacles. While On the Origin of Species dominates perceptions of his work, The Descent of Man and The Expression of the Emotions in Man and Animals had considerable impact, and his books on plants including The Power of Movement in Plants were innovative studies of great importance, as was his final work on The Formation of Vegetable Mould through the Action of Worms.
Title: The Autobiography of Charles Darwin
Content:  The Autobiography of Charles Darwin is an autobiography by the English naturalist Charles Darwin. Darwin wrote the text, which he entitled Recollections of the Development of my Mind and Character, for his family. He states that he started writing it on about May 28, 1876 and had finished it by August 3. The text was published in 1887 (five years after Darwin's death) by John Murray as part of The Life and Letters of Charles Darwin, including an autobiographical chapter. The text printed in Life and Letters was edited by Darwin's son Francis Darwin, who removed several passages about Darwin's critical views of God and Christianity. The omitted passages were later restored by Darwin's granddaughter Nora Barlow in a 1958 edition to commemorate the 100th anniversary of the publication of The Origin of Species. This edition was published in London by Collins under the title of ''The Autobiography of Charles Darwin 1809-1882. With the original omissions restored. Edited and with appendix and notes by his granddaughter Nora Barlow''.

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: The Voyage of the Beagle

Title: Natural Selection (manuscript)
Content:  Natural Selection is a manuscript written by Charles Darwin, in which he presented his theory of natural selection and its role in biological evolution. He did not publish the work while he was alive, but wrote an abstract, titled On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, which he published in 1859. Darwin regarded Natural Selection as his main work, while On the Origin of Species was written for a wider audience. He always intended to finish Natural Selection, but because of frail health, the publicity and work involved in publishing six editions of On the Origin of Species, plus other research and publications, he never got around to finish it. Natural Selection was transcribed after Darwin's death, and first published in 1975.

Darwin struggled for thirteen months to produce an abstract of his "big book", suffering from ill health but getting constant encouragement from his scientific friends. Lyell arranged to have it published by John Murray. On the Origin of Species proved unexpectedly popular, with the entire stock of 1,250 copies oversubscribed when it went on sale to booksellers on 22 November 1859. In the book, Darwin set out "one long argument" of detailed observations, inferences and consideration of anticipated objections. In making the case for common descent, he included evidence of homologies between humans and other mammals. Having outlined sexual selection, he hinted
