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.
