The study finds that a million -year -old skull is found in China can rewrite the timetable for human development, “This changes a lot of thinking”

A study found that the digital reconstruction of a million -year -old skull indicates that humans may have moved away from our old ancestors 400,000 years before thought and Asia, not Africa.

Researchers said that the results published on Thursday are based on the rebuilding of a discovered skull in China in 1990 and have the ability to solve “Muccle in the Middle” of human development.

But experts who did not participate in the work warned that the results are likely to be disputed and pointed to the continuous uncertainty in the timetable of human development.

It was previously believed that the skull, named Yunxian 2, belongs to a human pioneer called Homo Erectus.

But modern reconstruction techniques revealed the features closer to the species that had previously been believed to have existed only in human development, including recently discovered Homo Longi and Homo Sapiens.

“This changes a lot of thinking,” said Chris Strenger, an anthropologist at the London Natural History Museum, who was part of the research team.

“It indicates that a million years ago, our ancestors had already divided into distinctive groups, noting a former and more complex humanitarian division than he had previously thought.”

The results were shocked by the research team.

“From the start, when we got the result, we thought it was incredible. How could this be in the depth of the past?” Xijun Ni, Professor at the University of Vodan participated in the analysis, I told BBC News. “But we have experienced it again and again to test all the models, use all methods, and we are now confident of the result, and we are very excited.”

The researchers said that if the results were correct, this indicates that there would have been previous members of the early early factors, including primitive humans and Homo Sapiens.

Michael Petraglia, director of the Australian Research Center for Human Development at the University of Griffiths, who did not participate in the study, said that he “knocks water” on long -term assumptions stating that the first human beings were separated from Africa.

“There is a big change that is likely to happen here, as East Asia is now playing a major role in the development of hominin,” he told France Pascal.

“A lot of questions”

Search, It was published in the magazine ScienceAdvanced tomography techniques, lighting lighting and apparent reconstruction techniques for the full Yunxian 2 design. Then the team printed the symmetrical copies on a 3D printer, according to BBC News.

Scientists partially relied on another skull similar to the formation of their model, then compared it to more than 100 other samples.

The researchers said the resulting model “shows a distinctive mix of features,” some of which said, such as Homo Erectus, including the lower face.

But the other aspects, including their larger brain ability, are closer to Homo Longi and Homo Sapiens, according to the study.

“Yunxian 2 may help us to solve the so -called” muccle in the center “, a confusing group of human excavation between one million and 300,000 years,” Stinger said in a press statement.

Much of human development is still discussed, and Petraglia said that the results of the study are “provocative” although it is based on strong work.

“It is sound, but I think the jury is still outside. I think there will be many questions that were raised,” he said.

Andy Herves, an archaeologist at the University of La Trop, said he was not convinced of conclusions and that genetic analysis showed fossil formation, or form, “was not always an ideal indication of human development.”

“They have obtained this interpretation, which I do not think takes into account the genetic dates of these things that we know,” he told AFP.

“Although the study’s conclusions were reasonable, it was far from the temporary, and more evidence was needed to confirm.

He told BBC News: “This image is still completely unclear to us, so if the conclusions of this research are supported through other analyzes, perfectly from some genetic data, I think we will start with increasing confidence in it.”

The results are only the latest in a series of modern research that led to the complexity of what we thought we know about our origins.

pole Also known as “Dragon Man”, “ His name was only his name as a new type and human relatives in 2021, by a team that included Strenger.

The authors said that their work shows the complexity of our common history.

“Excavations like Yunxian 2 shows how much we still have to learn about our origins,” Stinger said.
