Scientists have discovered a new one Predka Allovica Who lived in South Africa two million years ago. According to a new study, he was supposed to walk upright like a modern man, but climb trees like a monkey, the portal writes daily Mail.
Scientists have discovered the bones of a species known as Australopithecus sediba, which could close a decades-old debate about how early human ancestors moved. Scientists refer to the discovery of the spine as having no connection with other human species. According to the available information, this species spent a long time on two legs, but also used its upper limbs – to climb trees.
An international team of researchers from New York and Johannesburg worked on the study. Bones of our ancestors were found in a cave in South Africa and Based on them, they were able to create the most complete picture of the spine of all known species of humankind.
Australopithecus sediba species first described in 2010A scientist named Lee Berger. Berger and his son discovered the remains of this species in Malaba Cave. Later it became clear that the remains may have belonged to the child and his mother.
The fossils mentioned in the new work were discovered in 2015, near Malaba Cave. Specifically, four vertebrae and a bone were found that connect the spine to the lumbar bone. It is likely that the remains belong to a woman called the scholar Issa. Its name in Swahili means “protector”.
Analysis of the remains showed that, like people, Even this species only has five lumbar vertebrae.
“The lumbar region is key if we are to understand bipedal locomotion, especially in the context of our ancestors. At the same time, we can understand how our ancestors initially stood on two legs and how they adapted to this change,” said Professor Scott Williams, of New York University.
An intermediary between two types of ancestors
When scientists discovered the remains of Isa, a woman of the genus Australopithecus sediba became one of the two skeletons of our ancestors that retained the lower back. At the same time, these remains are among the best preserved. This allowed scientists to gain a unique insight into the anatomy of this species.
They note the curvature of the spine, which clearly indicates that this species has already learned to walk on two legs. However, there are other factors related to this fossil. Most likely Jesus had a strong body. It is primarily associated with primates. This indicates that although Jesus could walk on two legs, But it has also been adapted for climbing.
Even previous studies suggested these types australopithecus sediba can be a transitional species between ancestors who walked upright and those who still climbed trees.
