‘The Expression of the Emotions in Man and Animals’ is Darwin’s classic examination of behavior as can be witnessed through the outwardly visible expression of emotions. The timeless question of ‘nature vs. nurture’ is one that has perplexed behaviorial scientists since the inception of the discipline. Is behavior a function of evolution or environment? Darwin’s examination of the subject from the perspective of expression as a proxy for the visible evolution of character in man and animals makes for a detailed study on the subject. Presented here is the fully annotated and illustrated edition.
