Human ancestors had a strange gait

The latest study of anatomy immediate ancestors of man can shed light on his life, and not only. For example, researchers have suggested that human ancestors went a completely different way than previously believed. It is possible that before people moved slightly pigeon-toed gait.

First Australopithecus sediba skeletons were found in 2008, 9-year-old son of one of the scientists in South Africa — the cradle of humanity, where archaeologists have repeatedly found the remains of our ancestors. Australopithecus — a "southern apes" and sediba — a word from the language Sotho, one of the 11 official languages of South Africa, meaning 'fountain, the water column. " Scientists believe that man evolved from this very type of hominid.

Sediba lived almost 2 million years ago — scientists believe that this was when there were species Homo. These Australopithecus was a strange mixture of human and primate traits that supports the theory of the origin of man is from sediba.

Scientists have carefully studied the anatomy of sediba remains found. Archeologists have found skeletons of young men and women, as well as the tibia of an adult male. Discovery allowed scientists to learn more about the anatomy of early hominids. By the way, members of the family of hominids are as modern Homo sapiens and their immediate ancestors.

The researchers add that a predisposition to climbing our ancestors in the trees tells shape of the blades, similar to the anatomy of the orangutans.

In addition, the sediba were fingers with which you can keep any gun. "They have a firm grip needed not only to climb trees, but also to hold fast to implement — the researchers explain. — However, there is still no precise evidence of the existence of any guns. "

Judging by the structure of the legs sediba, they moved quite unusual way. For example, a small heel means that they go by rotating the knees and hips inward. Perhaps this primitive gait — a transition from tree-climbing to upright posture.

Analysis of the spine sediba revealed that they had a curved waist, almost like modern humans, but it was longer and more mobile. The researchers suggest that this feature helps them to travel. During the walk we will slightly rotate the torso, waving his arms at the sides. Did sediba just turning the body from side to side.

Such findings demonstrate the need for further research remains in South Africa — the region may hide many more archaeological mysteries.
