Every day we experiencc one of the wonders of the world around us without even realizing it It is not the amszing plexity of television. Nor the impressive tcchnology of transport The universal wonder we share and
Experience is our ability to make noises with our mouths, and so transmit ideas and thoughts to each other’s minds. This ability es so naturally that tend to forget what a miracle（奇迹）it is.
Obviously, the ability to talk is something that marks humans off from animals. Of course, some animals have powers just as amazing. Birds can fly thousands of miles by observing positions of the stars in the sky in relation to the time of day and year. In Nature’s went show, humans are a species of animal that have deve pod their own special act. If we reduce it to basie ferms, it’s a ability for municating information to ther by varying sounds we make as we breathe out.
Not the to don’t have other powers of munication. Our facia. expressions convey our emotions, such as anger, or jout or disappointment. The way we hold our beads 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 bead or drooping tail shows a readiness to take second place in any animal gathering.
Such a means of munication is a basic mechanism that animals, including human beings, instinctively acquire and display. Is the ability to speak just another sort of instinct? If so, how did human beings acquire this amazing skill? Biologists can readily indicate that particular area of our brain where speech mechanisms function, but this doesn’t tell us how that part of our bodies originated in our biological history.
