Some gestures such as shaking the head and sticking the thumb or middle middle finger up have different meanings in different societies. The smile is universally accepted as a symbol of happiness or good faith. Some thought suggests that this is related to behavior developed in apes.
Here's a thought I had. If there were ever any societies that did not use the traditional smile as a sign of happiness and good faith they would have disappeared quickly. When they contacted other societies they would be viewed with distrust or anger because the non-smiling society would never appear to be happy. Each time the non-smilers attempted to show openness and good faith to the smilers they would make some kind of face that may look horrible to us. Hence they would be shunned or attacked.
Ultimately, it is useful for all societies to have a common way to show good will towards one another. This promotes cooperation.
