"Evolution of Laughter"

It turns out that we use laughter as a part of survival. Animals such as apes used it when they are playing so that the other ape knows he is not trying to hurt him. In humans , laughter brings us together because it helps us connect. It is believed that is allowed ancient humans who were not biologically related to cooperate with each other. Laughter bonds us and we create babies and then the babies laugh which then bonds us to the babies and so on.
