The Descent of Man, and Selection in Relation to Sex

"The Descent of Man, and Selection in Relation to Sex" by Charles Darwin, published in two volumes in 1871, expands on his theory of evolution, focusing on human evolution and the concept of sexual selection. Darwin explores how human traits and behaviors have evolved not just through natural selection but also through the preferences of mates. This work delves into the similarities between humans and other animals, arguing that many human characteristics are the result of evolutionary processes shared across species.
