COMMUNICATION{bow-bow theory}

We all know that when a dog bark it goes'bow-bow. But how does that explain the orgi of langauge?
According to the bow-bow theory, langauge began as initation of the sound made by the animals andoter natural sounds. Thus the word 'moo'describes the noise of cow, while 'meow' sound just like a kitten cry and 'plop'sound just like a drop of water falling.
But this is only a theory and many people don't agree with it.
