Language function originates face expression

Australian scientists say human language functions can emerge very early and are marked by the phenomenon of monkey mouth copy when they communicate with each other. This study was published in the recent issue of the issue of contemporary digital biology.

Mr. Tecumseh Fitch, head of the Department of Biological Cognition at the University of Vienna and colleagues from Princeton University, conducted the study.

The results showed that most monkeys have mouth-copy movements when they meet. This process though only emits very small sounds, but they are not vibrations into the sound that comes from the throat.

According to initial recognition, this sound is caused by the continuous movement of the lips. However, observing the monkeys through X-ray, the scientists discovered that the sound above due to a series of complex movements quickly coordinate between lips, tongue, jaw and small U-shaped nail bones. The frequency of these movements is 5 times per second. It is similar to the speed of movement of related organs in the oral cavity of the person when speaking.

Scientists say, when we say, the organs involved in the oral cavity also move so fast and rhythmically. At the same time adjusting these vocal cords creates basic sounds, so that it turns into consonants and vowels.

When monkeys communicate with each other, the mouth-to-mouth movements and related organs used by monkeys communicate with each other strangely with the movements of the organs involved when speaking in humans.

Therefore, scientists believe that human language function does not originate from the call of primates, but derives from facial expressions when monkeys communicate and spread. through long-term evolution.
