Modern humans lived in what is now China by 45,000 years ago. This discovery means our species arrived in this region thousands of years earlier than commonly thought, probably via a northern route through present-day Siberia and Mongolia.

A team co-led by Francesco d'Errico Researchers from the University of Bordeaux in France reexamined an archaeological site in northern China called Shiyu. Originally, he was excavated in 1963 during the turbulent period of China's Cultural Revolution. “It couldn't have been a better time to find such an important site,” D'Errico says.

Shiyu is an outdoor site located in a river gorge. There, 30 meters deep, sand and other sediments were deposited, which the first excavators divided into four horizontal layers, from the bottom of which the second layer contained human It was found that there was evidence of residence in

Excavators discovered more than 15,000 stone artifacts and thousands of animal bones. There was also part of a hominin skull, which anthropologist Wu Lukang identified as a modern human.homo sapiens).

Some of the artifacts were later transferred to the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing. However, those left behind at the local facility were lost, including the hominin bones. “We own maybe 10 percent of the stone tools,” D'Errico says.

D'Errico and his colleagues re-excavated Shiyu to determine its age. They dated 15 sediment samples using a technique called photostimulated luminescence and carbon-dated 10 animal bones and teeth. The hominid layer is approximately 44,600 years old.

D'Errico believes the excavator was “knowledgeable” and correctly identified the skull.

The Shuyu tribe is probably homo sapienssay Alina Katzenovic from the Institute of Archeology and Ethnology in Novosibirsk, Russia, was not involved in the study.

The new study therefore suggests that modern humans arrived in northern China about 45,000 years ago. This would postpone the arrival of our species to China by about 5,000 years.Derico claims to be the next oldest homo sapiens China's site Tengen Cave 40,000 years ago.

Some researchers argue that our species may have arrived earlier than that, up to 260,000 years ago. However, D'Errico points out that researchers: criticized much of the evidence As for the presence of such early humans in this region.

Humans probably entered Asia from Africa and spread through multiple routes, Katzenovich said. They not only explored the tropical southern regions of Asia, but also headed further north. Katzenovich says there are signs of modern human presence in the area. Obi Rakhmat Cave Uzbekistan 48,800 years ago. Perhaps our species reached Shiyu and then China via this route. north route.

When modern humans reached new areas, they encountered hominids that were already living there, such as Neanderthals and Denisovans further east. Genetic evidence shows that we interbred with them. There may also have been cultural exchanges, and the Shiyu artifacts also include what appear to be more ancient human tools.

There is also evidence of long-distance contact. The Shiyu team identified four fragments of obsidian, a volcanic glass. They were able to track them as far as 800 and 1000 kilometers northeast of Shiyu. D'Errico said it was unlikely that the residents traveled this distance themselves, so they were probably part of the group's network. In line with this, Kazenovich said some of Shiyu's artifacts resemble items found as far east as Korea.
