The Descent of Man, and Selection in Relation to Sex is a book by English naturalist Charles Darwin, first published in 1871, which applies evolutionary theory to human evolution, and details his theory of sexual selection, a form of biological adaptation distinct from, yet interconnected with, natural selection. The book discusses many related issues, including evolutionary psychology, evolutionary ethics, differences between human races, differences between sexes, the dominant role of women in mate choice, and the relevance of the evolutionary theory to society.

As Darwin wrote, he posted chapters to his daughter Henrietta for editing to ensure that damaging inferences could not be drawn, and also took advice from his wife Emma. Many of the figures were drawn by the zoological illustrator T. W. Wood, who had also illustrated Wallace's The Malay Archipelago (1869). The corrected proofs were sent off on 15 January 1871 to the publisher John Murray and published on 24 February 1871 as two 450-page volumes, which Darwin insisted that it was one complete, coherent work, and were priced at £1 4 shillings.

Within three weeks of publication, a reprint had been ordered; and 4,500 copies were in print by the end of March 1871, netting Darwin almost £1,500. Darwin's name created demand for the book, but the ideas were old news. "Everybody is talking about it without being shocked," which he found, "...proof of the increasing liberality of England" (see the 1871 book review in External links).
