Apparently, the man began to walk on two legs because of the rocky terrain, but not because of climate change

Man became bipedal because of the abundance in Eastern and Southern Africa, the mountains - a landscape in this region was formed in the Pliocene through volcanic activity and a shift of tectonic plates. Hominids, our ancestors were forced to use the gorge, crevices and caves, because it could help make it easier to lure prey into a trap. In addition, the natural formation of the natural man used as a shelter.

According to traditional theory, the man began to walk upright because our ancestors had to leave the trees and begin to live on the earth because of climate change and reduce the number of forest. York researchers believe that the reason is not only that: the vertical position of the body gave hominids benefits when driving over rough terrain - so they could climb the rocks, better balance and faster for them to move in earlier unnatural conditions.





Change hands and fingers from bipedal hominids allowed them to develop the necessary skill and learn how to use tools, which contributed to their further evolution. Vertical development of the spine and legs hominids given the opportunity to study the surrounding plain from a height and efficiently search for prey and find new places to hide.

The mountainous terrain could also contribute to the development of cognitive skills such as navigation and the ability to communicate, which influenced the development of the human brain and social functions - the ability to work and team cooperation.
