7 million years ago!It is known that the earliest people belong to the upright walking time determined

The British "Nature" magazine recently published a paleontology report. Scientists showed the analysis of legs and forearm fossils that the earliest known people -Chad Shahe people walked with both feet 7 million years ago. These discoveries are based on the analysis of similar conclusions before.

In 2001, a large number of fossils discovered in Chad made people naming a new species of early people (including existing human and other categories of extinct relatives) -Chadsha, which dates back to about 7 million years. forward. Analysis of a nearly complete skull when discovery shows that Chadsha people may walk in both feet. This is a typical feature of human genus as an upright walking animal. The arms and leg bones discovered at the same place were not described before, which provided an opportunity for verifying the assumption.

These arms and leg bones 3D models. From left to right: femoral; left and right ulnar.

The Research Team of the University of Pavitier provided an analysis of a left thigh bone (femoral) and a pair of forearm bones (ulnar). These bones came from the original location of the Chadsha people in 2001. The author revealed that the anatomical structure of the femur shows that about 7 million years ago, the Chada people walked with both feet on the ground and supported the prediction of skull evidence. In addition, the author emphasizes that the characteristics of the ulnar are consistent with the characteristics of adapting climbing, but the conclusion needs to be treated with caution. For example, the functional pattern of the ulnar indicates that the Charlodes can climb trees up and down, which may be mounted through some form of grip and limb.

The research team said that shortly after the differentiation of humans and chimpanzees, early humans evolved their ability to walk, while retaining the characteristics of bone bones that allowed climbing.
