The Expression Of The Emotions In Man And Animals Penguin Black Classics

“The Expression of the Emotions in Man and Animals” (Penguin Classics / often issued in black livery) is Charles Darwin’s 1872 study of how humans and other animals show feelings through faces, voices and gestures. It was a central part of his “human” series, arguing that emotional expressions like smiling, frowning or baring teeth have evolved and are shared across species, supporting his broader theory of evolution.
