The Expression of the Emotions in Man and Animals, livre ebook

The Expression of the Emotions in Man and Animals is Charles Darwin's third major work of evolutionary theory, following On the Origin of Species, and The Descent of Man. In this book, Darwin sets out some early ideas about behavioural genetics, and explores the animal origins of such human characteristics as the lifting of the eyebrows in moments of surprise and the mental confusion which typically accompanies blushing.
