Experts who investigate the evolution of the human being consider that oral expression, besides being characteristic of evolution, is the result of being able to walk on the two legs.

According to the researchers of evolution, they have been decisive moments of evolution. One of them walk on the two legs. When man learned on foot, he had the opportunity to use his hands freely, but not only that, but also physiological changes of great importance emerged in the future, including speech. When standing up, the relationship between walking and breathing was not as narrow as walking on four legs. This flexibility allowed man to control the respiratory rhythm and, finally, to start talking.
