some scientists think they are yannaya from the grasslands of the Black Sea region of Russia And the descendants of the nomadic afanasievo because of their unusual height, woven wool clothes, and animal husbandry centered culture

another hypothesis is that they are farmers who immigrated from Bactria or now the desert oases of Afghanistan, Turkmenistan and Uzbekistan, which is based on the similarity of their agricultural and irrigation systems

now, the mystery has finally been solved

according to gene sequencing, these well preserved remains can be traced back to stone age hunter gatherers living in Asia about 9000 years ago. They are not immigrants from other regions, but indigenous people who have lived here for a long time

these remains are genetically independent. Miraculously, they have learned the same way of raising livestock and growing grain as other groups

Michael frachetti, an archaeologist at Washington University in St. Louis, said that this discovery shows that cultural exchange is not always accompanied by genetic relationships. These people just communicate, but that doesn’t necessarily mean getting married and having children

Professor Cui Yinqiu, School of life sciences, Jilin University, and researchers from the Institute of Paleovertebrates and Paleoanthropology, Chinese Academy of Sciences, Seoul National University, Harvard University and Max Planck Institute in Germany participated in the study

the remains are well preserved from hair to clothing, which is of great research value

since the beginning of the last century, these remains have been found in the cemeteries of Xiaohe culture, which are scattered in the Taklimakan Desert in Xinjiang, China

these remains were found in a wooden boat shaped coffin covered with cowhide and decorated with horned ox skulls

Alison Betts, an archaeologist at the University of Sydney, Australia, said: “The desert is one of the worst places on earth. There, the bodies are buried in ship shaped coffins wrapped in cow leather. The hot, dry and salty environment in the desert naturally preserves them. So everything from their hair to their clothes is intact. Before this latest research, we knew enough about the physical condition of these people, but we didn’t know him I don’t know who they are or why they are there. ”

she added that the remains were buried over a time span of more than 2000 years, which can be traced back to an important period in the history of Xinjiang, when ancient people were changing from hunter gatherers to farmers.

some late remains were dressed in wool Objects and clothing are similar to those found in western culture. There are millet, wheat, animal bones and dairy products in these tombs. This is evidence that farming and animal husbandry technology has cultural characteristics in other parts of Eurasia. Therefore, the researchers speculate that these people were originally immigrants from the West and passed through Siberia, Afghanistan or central Asia.

gene sequencing shows that The researchers sequenced the genomes of 13 human remains from 4100 to 3700 years ago and five human remains from 5000 to 4800 years ago in Northern Xinjiang hundreds of kilometers away.

then they compared the genetic maps of these human remains with those of more than 100 ancient and more than 200 modern populations from all over the world Groups were compared.

they found that some genomes of individuals in Northern Xinjiang were similar to those of Bronze Age immigrants living in Altai Mountains in Central Asia 5000 years ago, which supported an early hypothesis.

but these 13 remains did not Common ancestor. Choongwon Jeong, a population and evolutionary geneticist at Seoul National University, said that they seem to be related only to hunter gatherers living in southern Siberia and now Northern Kazakhstan about 9000 years ago.

in Tarim Basin (Tarim) Evidence of dairy products was found next to the youngest mummy in the upper layer of the cemetery, so the researchers analyzed the calcified plaque on the teeth of some older mummies to understand the history of dairy products. In the plaque, they found milk protein from cattle, sheep and goats, indicating that even the earliest settlers here ate dairy products.

Research The researchers said in the paper that the earliest Tarim Basin (Tarim) Culture seems to originate from a genetically isolated local population, who adopted the practices of neighboring herdsmen and farmers, which enabled them to settle and prosper in the changing Taklimakan desert river oasis.

Kerry Christina Wariner, a child archaeologist and co-author of the paper at Harvard University in Boston, Massachusetts, said that the study revealed “Diversified ways of population migration and non migration, and how ideas pass through and spread with the population”
