According to Charles Darwin Emotional Expressions Can Be Explained by Way

According to Charles Darwin emotional expressions can be explained by way of three principles, including the principle of antithesis which holds that:

A) expressive behaviors that helped individuals survive in the past will be more likely to reoccur in the future as compared to expressive behaviors that threatened an individual's well-being in past situations.
B) opposing emotional states will be associated with opposing emotional expressions.
C) the more stressed an individual, the more likely they are to release undirected energy through random expressions.
D) the size of the familial group determines the level of competition between individuals as well as the intensity of the emotional expressions that develop in the offspring within that group.
