I'm currently reading a book by a Russian biologist and paleontologist Alexander Markov. Today, while reading the book, I came across an interesting idea exploring the origin of human language. However I must say that it wasn't the first time I encounter this theory. It suggests that human language originated from the human need to find out who is trustworthy and who is not. The way of finding it out were gossips. As an example he provides experiences that Jane Goodall observed by chimpanzees. There was a cannibal chimpanzees who kidnapped children from other chimpanzees and ate them. One day a chimpanzee whose children were attacked by the cannibal chimpanzee spotted the cannibal chimpanzee. The attacked chimpanzee was in a group of other male chimpanzees and she started making sounds and noise while approaching the cannibal chimpanzee, as though she was trying to say that the cannibal chimpanzee was bad. The male chimpanzees started behaving towards the cannibal chimpanzee aggressively as though they wanted to punish her. This scene can be a clear example of how the human language came into existence.
