The Descent of Man

"The Descent of Man" is a book by Charles Darwin, published in 1871. In it, Darwin extends his theory of evolution, originally introduced in "On the Origin of Species," to humans. He argues that humans share a common ancestor with other primates and that our physical and psychological traits have evolved through natural selection. The book also explores the role of sexual selection in shaping human characteristics, such as mate choice and competition. Overall, it emphasizes the continuity between humans and the animal kingdom, challenging traditional views of human uniqueness.
