How Animal Have Conversation
Although a number of different theories have been displayed so far, there is still no direct evidence which tells us how the language has originated. It is certain that divine theory is one of the oldest thesis, suggesting the language as the gift of the God to mankind. Judeo Christians believe that Adam was given the power to name all the things that the world consists of. God communicated with the first people in a language that was easily understood by their brains. In terms of divine creation, many experiments have been carried out since the Ancient Times. For instance, an Egyptian pharaoh, Psammetichus, decided to place two infants in the mountains, isolating them from society. They were only in close contact to mute servants. Surprisingly, after several years they were able to say a word meaning ‘bread’ in a language which had not existed for a long time. Another interesting examination was carried out by James IV of Scotland thousands years after Psammetichus. Indeed, he repeated the same experiment, getting significant results: isolated children were capable of speaking Hebrew. Therefore, James IV formulated a thesis that Hebrew was the language Adam and Eve used in order to communicate in Eden.
Combined with other body language, in a specific context, many gestures such as yawns, direction of vision, and so on all transmit meaning. As with human beings, who may smile or hug or stand a particular way for multiple reasons, many animals reuse gestures as well.
