Charles Darwin presented the theory of evolution by in 1859. The theory of evolution is described as the change over time of an organism that gains adaptive traits. These traits increase an organism’s fitness. An organism’s fitness is the organism’s ability to pass on its genes and produce offspring. Certain characteristics increase survivability and fitness. These traits are passed down through the genes. Less favorable traits are less likely to be passed on as the organism’s ability to survive and pass on genes are lowered. Through this, an organism’s traits passed to the offspring allows them to be better adapted to their environment. Van Hooff hypothesizes in his article, “A Comparative Approach to the Phylogeny of Laughter and Smiling”, …show more content…

Van Hooff explains that “the similarity existing between...the silent bared-teeth display and our human smiling...and the similarity between the relaxed open-mouth display and our laughter” reveals a phylogenetic connection. Although humans use smiling and laughter interchangeably, there are certain social scenes where it is inappropriate to use them. This much like how monkeys use the silent bared-teeth and relaxed open-mouth displays for certain situations. Furthermore, he states that smiling and laughing serve a similar function as silent bared-teeth and relaxed open-mouth displays. Smiling and laughter are often used to show friendliness and encourage a playful environment. He performed a study to see what people associated with smiling and laughter. It was found that there was a high correlation between positive attitudes (friendliness, playfulness) and smiling and laughing. There was a low correlation between negative attitudes (aggression, submission) and smiling and laughing. From this, Van Hooff concludes that although they function differently in apes and humans, there is phylogenetic evidence that silent bared-teeth and relaxed open-mouth displays are precursors of human laughter and …show more content…

In selections from Provine’s “Laughter, it explains how some people laughed while looking at each other. Although it the people claimed that they looked at each other because the third person was not funny. Provine explains the subliminal message of this act. By laughing together, an outgroup and ingroup are formed. Those laughing together are the ingroup and those excluded become the outgroup. Much like how the displays monkeys use to retain social hierarchy, laughter functions like so. The social hierarchy of ingroups and outgroups are kept in place by the use of laughter. R. Martin’s “A brief history of the meaning and concept of Humour” relates to Van Hooff’s study that revealed a high correlation between positive attitudes to laughter and smiling. Although Martin looks specifically at humor, the association is still the same. In history. Humour was often seen as a negative thing. The act of laughing at other’s misfortune, a type of superiority, and was seen as aggressive. It was commonly associated with aggressive ways of provoking laughter. However, over time, humor was seen more desirably and received more positively. Humour revealed a sense of intellectuality. It was also related to revealing traits like warmth and friendliness. Like smiling and laughter, humor
