Scientists have proven that people have become simple when they still lived in trees

The most comprehensive skeletal analysis of a human ancestor, conducted by a research collaboration with the participation of the University of Liverpool, provides compelling evidence that our Ancestors were simple even when they were actually animals and lived in trees.

First skeleton bones by age The 3.67 million-year-old StW 573, titled Little Foot, had 12 foot bones and fragments of the leg bone described in the 1990s The other part of the skeleton survived two decades of difficult excavations, purifications, restorations and analyzes. She was found in a very deep cave: the bones became a concrete matrix, informs UkrMedia.

As part of a study published in the journal Nature Science, Professor Robin Crompton, honorary researcher in the field of bone and muscle biology at the University of Liverpool, and his colleagues. analyzed how Little Foot could walk.

More than 90% of this skeleton belongs to the representatives of the Australopithecus. Skettle Little Foot is the first of the bases that perfectly retain the limbs.

Studies confirm the hypothesis of Professor Ronald Clark of the University of the Witwatersrand, who discovered the skeleton. He thinks that two species of Australopithecus, Australopithecus africanus, a smaller species that lived in trees, and Australopithecus Prometheus, which probably resembled a modern man, lived simultaneously in South Africa.

"In this hominid, the first of all revealed, the lower limbs were longer than the upper limbs – as we have." This is an important finding, because in the earlier hominids, the archipedents preceding Australopithecus, the arms were longer than the legs, like superior primates, such as gorillas, explains Professor Crompton.-It means that she has moved a lot on two limbs In addition, Little Foot had a femoral joint, like ours, that could carry the action of the trunk to the leg and back.Although the legs of Little Foot are longer than their hands, they have Not yet reached a relatively long length, like that of humans.This way she could not carry objects as well as us.However, it was much easier for her to climb trees than modern man.
