There are many theories. Some speculate it is a fear response. Others think it may have had an evolutionary advantage as a development in communication. If you want a good book on the subject try Robert R. Provine's Laughter: A Scientific Investigation.

The main theory is that in caveman times, laughing expressed relief at the passing of danger when, for example, they just missed being charged by bulls. Also, laughter clears the system of negative or confused emotions due to stress and the like.
