On The Origin of Species is Darwin's most famous work, but he also wrote a much lesser known book titled The Expression of the Emotions in Man and Animals, where he claimed that all humans show emotion through similar behaviors.
This view is one that psychologists today generally agree with, affirming that certain expressions of emotion are common to all of us, regardless of race, culture, or age. One of these universal facial expressions is a smile.
