The Descent of Man

Focusing on human evolution, Darwin's work delves into the origins of humanity and the development of physical and mental traits. He examines the concept of race, arguing against the notion that different human races are separate species. The book introduces his theory of sexual selection and discusses natural selection's influence on society, laying groundwork for eugenics and Social Darwinism. As a pivotal text in evolutionary science, it remains relevant in contemporary discussions on human development and diversity.
