This coincides with crying when sad, as well. I am not a psychologist, however it is widely known that those who bottle up their powerful feelings develop emotional and psychological problems if the action persists. Those who release their stress however can recover from their problems much faster. Therefore, those who release their problems are able to cope with their trauma. Our ancestors may have evolved the act of crying because the advantages of releasing their stressful emotions through the act of crying may have somehow allowed them to live and find mates better than those who could not release it in such a way. Of course, this is a complete guess as I am not an expert in the matter and do not claim to be.
Any strong emotion can make you cry - crying is a way to release emotion. Often, people will cry if something makes them very happy, or if it is very beautiful.
Imagine if you have two different bacteria. They are just hanging out, doing what they do, enjoying their nice, nutrient rich environment. They get to divide over and over...life is good. Then the nutrients start to dry up, all of a sudden there is no more food! The bacteria that cannot produce endospores shrivel up and they, and all of their offspring die! The bacteria capable of that final internal division and capable of using its internal goo to use as an iron clad capsule to protect its genetic material can then go metabolically dormant for...ever. When the environment improves it can resume its happy division. 2 bacteria enter...one bacteria leaves! There is your evolutionary advantage.
I think that crying is a sign of immense emotion. When you cry-it is a release of that emotion. Sadness/anger and happiness are the two extremes of the emotional phenomena.
