cries some. Now here is my question. Do babies cry because of some evolutionary development that came about during the "dawn" of human evolution? I believe that almost everything that we do, by nature, we do because at some point in our evolutionary development, it was to our advantage to do that thing. It was a help in our survival. Babies cry when something is wrong. If they did not cry, very serious things might go unnoticed. So, do babies cry because of evolutionary lessons learned at the "dawn of time?"
