In Darwin’s (1872) evolutionary theory, he postulated that facial expressions of emotion are inherited. On the other hand, scholars have questioned if culture influences one’s bodily expression of emotions. Broadly, the theories can be categorized into two models: The cultural equivalence model predicts that "individuals should be equally accurate in understanding the emotions of ingroup and outgroup members" (Soto & Levenson, 2009). This model is rooted in Darwin’s (1872) evolutionary theory, where he noted that both humans and animals share similar
