Thanks to Charles Darwin we now know that it’s not just the eyes that are “the windows to the soul”. He first wrote about the subject of facial expressions in his 1898 book titled The Expression of the Emotions in Man and Animals (the link includes the work in its entirety).

Ekman and Friesen (1969) expounded on Darwin’s theory, hypothesizing that universal facial expressions were to be found in the relationship between distinctive patterns of the facial muscles and particular emotions. In 1971 they traveled to Papua New Guinea to test the Fore tribe, a people who had minimal contact with outsiders. The researchers found that the Fore were able to accurately identify the expressions of emotion in photographs of people from cultures with which they were not yet familiar (here’s a link to a fascinating NPR Ekman podcast).
