"Descent of Man," written by the seminal naturalist Charles Darwin, was first published in 1871. This landmark work builds upon Darwin's earlier theories of evolution presented in "On the Origin of Species," focusing particularly on human evolution and the role of sexual selection. In this text, Darwin explores the similarities between humans and other animals, arguing for a common ancestry and delving into aspects of psychology and behavior. The book was instrumental in fostering debates on human origins and has had a profound and lasting impact on the fields of biology, anthropology, and the social sciences.
