This collection brings together two landmark works by Charles Darwin — The Descent of Man, and Selection in Relation to Sex and The Expression of the Emotions in Man and Animals — in an Italian-edition titled Scritti antropologici. It addresses themes of human evolution, sexual selection, and the biological basis of emotion and expression. Darwin’s style remains rigorous yet accessible, blending scientific observation with philosophical reflection and broadening the scope of his evolutionary theory into the realm of anthropology. The book’s contribution lies in situating humanity within the natural world and applying a unified evolutionary framework to behavior, anatomy, and culture.
