Figure 1 shows the human throat under the throat of the jaw. Most mammalian throats are usually placed at a height high enough to be used intranasally for simultaneous breathing and swallowing. This development is also seen in small babies. As humans ages, throats slowly begin descending to the final position of adulthood and arrive within 3 to 4 years (Fitch, 2000). A similar decline in the throat is most likely to occur during human evolution.
The emergence of throat decline is an important innovation in the evolution of speech, but this sound production mechanism involves cost. This is causing and warning of human-specific dysphagia (such as swallowing disorder), but the well-known Heimlik motility asphyxia is the fourth leading cause of accidental death in the USA (USA Injury report) . It is expensive to have a throat at the top of the trachea, so there are already forms of voice and vocalization before our various human vocal folds evolve (Lieberman, P., 2007). Furthermore, with the risk associated with the development of such a pathway, evolution is motivated to advance its own advantages and is most likely to increase the benefits of voice function. That is, the benefits of throat drop (voice communication system) make biological risk worthwhile.
Several theories suggest that people formed communication in the process of evolution. Audio is its main means. However, many researchers believe that speech is a secondary factor in sound, order and combination. Music here serves as a bridge between the original screams and can be observed as a means of communication between animals and human languages. Like a speech, music follows certain rules, has a structure, and is somewhat language. The most attractive feature of music is that it aligns certain human abilities with one another. Music is more than just a sound. It is also melody and rhythm, and often it is text. Therefore, when people listen to music, they experience movement (sports reaction), experience the image, and feel emotion. In addition, there is an important social element
