Evolution of emotion Evolution of emotion The study of the evolution of emotions dates back to the 19th century. Evolution and natural selection has been applied to the study of human communication, mainly by Charles Darwin in his 1872 work, "The Expression of the Emotions in Man and Animals". Darwin researched the expression of emotions in an effort to support his theory of evolution. He proposed that much like other traits found in animals, emotions also evolved and were adapted over time. His work looked at not only facial expressions in animals and specifically humans, but attempted to point out parallels between behaviors
Gender and emotional expression involves both detection and expression of emotions or moods. The ability to detect non-verbal cues leads to successful communication of emotions. In computer-mediated communication (CMC), the absence of body language and visibility restricts one's ability to correctly recognize other's emotions.

Surprisingly, there is no static gender difference in the use of emoticons. In some studies, both men and women display an increase in emoticon use in the context of a mixed-gender group chat. Others show that men use more emoticons
