Standing, or bipedalism, refers to the action of walking using two legs. That is to say; It is known as the ability to stay in the upright position, stand foot and move in this way using only your legs. Birds and humans are bipedal. The development of this ability was an important characteristic in the evolution of man.
The question of when the situation began in hominids is a classic in scientific discussions of human evolution. When he was a young man studying at the university, in the 70s of the last century, he was associated with the use of tools by the genus Homo. Therefore, it was related to the emergence of stone technology, since generally two hands are needed to make an instrument, that is, the distal parts of the upper extremities must be free to execute the sequential striking movements, intended to obtain a certain morphology. for later use.
The discovery of the fossilized footprints of Laetoli (Tanzania) 3.2 million years ago, and more similar to those of the species of the genus Homo, opened the door to the contrast of the existence of the erect position in a very ancient period, could It was concluded that Australophitecus afarensis was already walking upright. That is, before the stone technology existed, the erect position was already consolidated.
Bipedalism was probably the physiological transformation that made us men or homo sapiens. Scientists estimate that we have been walking upright for approximately four million years.
Actualmente sabemos que la presencia representa una adquisición importante para que los homínidos se adapten más tarde, y como consecuencia del cambio climático, a la sabana, obteniendo una mayor visión en la distancia, disminuyendo la captura de calor y favoreciendo el posible transporte con extremidades superiores ya liberadas, etc.
