Where did languages originate?
Languages originated from mans basic desire to communicate needs and wants. First through body language and grunting and then into pictures drawn in the sand, dirt and on other surfaces. So when people began to draw pictures and make grunts or word like sounds the community in which this took place began to make the same sounds for a particular picture thus verbal communication was born. Different languages resulted from wide spread communities of prehistoric men. It stands to reason that as man was first developing verbal skills, no two communities used the same sounds to describe the same object of reference as Darwinism took its toll on early man and communities died out, some grew. When they did, man would travel in search of food and mingling with other tribes of early man sharing new technology and speech. Eventually one language was adopted per region.
