The Expression of the Emotions in Man and Animals

"The Expression of the Emotions in Man and Animals" by Charles Darwin explores how humans and animals communicate feelings through facial expressions, gestures, and body language. Darwin suggests that many emotional expressions are universal, linked to evolutionary history, and serve social functions like warning or bonding. He argues that these expressions develop naturally and are often similar across species, reflecting common origins. The book emphasizes that understanding these signals helps us better interpret others' feelings, fostering empathy and social harmony. Overall, Darwin's work highlights the biological roots of emotional expression shared across the animal kingdom.
