The universal wonder we share and experience is our ability to make noise without mouths, and so transmit ideas and thoughts to each other"s minds.

If we reduce it to basic terms, it"s an ability for communicating information to others, by varying sounds we make as we breathe out. Not that we don"t have other powers of communication. Our facial expressions convey our emotions, such as anger, or joy, or disappointment. The way we hold our heads can indicate to others whether we are happy or sad. This is so-called "body language". Bristling (直立的) fur is an unmistakable warning of attack among many animals. Similarly, the bowed head or drooping tail shows a readiness to take second place in any animal gathering. Such a means of communication is a basic mechanism that animals, including human beings, instinctively acquire and display. Is the ability to speak just another sort of instinct?
