The Descent of Man, and Selection in Relation to Sex
![](https://commons.wikimedia.org/wiki/Special:FilePath/Darwin_-_Descent_of_Man_(1871).jpg?width=300)
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.
