China News Service, Beijing, September 2 (Reporter Sun Zifa) A recent study of the paleogenomics of foreign regional populations led by a team of Chinese scientists confirmed from a genetic perspective that the Uzbekistan region located in the western part of the Tianshan Mountains is an active area for migration and communication.
Through the capture, sequencing and analysis of large-scale nuclear genomes, the study revealed the genetic structure changes and genetic continuity of the Uzbekistan population from the Bronze Age to the Iron Age, as well as the genetic connection between the Yueshi population and the Guishuang population.
By the Chinese Academy of Sciences (Vertebrate Paleontology and Paleoanthropology Zhong Keyuan ancient of the spine) paid Qiaomei team with Professor Wang Jianxin Northwestern University-led joint Uzbek Academy of Sciences this important research results Institute of Archeology units together to complete, Recently published online in the professional academic journal "Molecular Biology and Evolution"
Academy of Sciences Zhong ASTRI ASTRI Academy Why carry out the paleogenome research of the Central Asian population?
Why carry out the paleogenome research of the Central Asian population? Researcher Fu Qiaomei, the co-corresponding author of the paper, said that the ancient nomadic people's migration from China to Central Asia was an important event in the process of world history, and it played an important role in the cultural exchanges and interactions between the East and the West on the Silk Road
Archaeological studies have found that the Rabat cemetery located in the Iron Age in southern Uzbekistan has been confirmed as a relic of the Yueshi culture from the perspective of geographical distribution, burial customs and sources, religious culture, and economic formation.
religion Uzbekistan is located on the southern edge of the Eurasian steppe and the western region along the Tianshan Mountains.
Fu Qiaomei said that in order to explore the migration and communication of ancient populations at these sites and other scientific issues, and to directly observe the integration of their genetic components from the perspective of genetics, her research team obtained the Rabat Cemetery in Southern Uzbekistan from International Archaeology.
Analyze the genetic structure of Yueshi and Guishuang culture-related populations
Analyze the genetic structure of Yueshi and Guishuang culture-related populations Previous studies have shown that the main genetic composition of the population of the Bactria Marghiana civilization in the Bronze Age consists of the composition of the Iranian agricultural population (about 60-65%) and the composition of the Anatolian agricultural population (about 20-25%).
The first author of the paper, Zhong Keyuan ancient spine associate researcher Vikas Kumar (Vikas Kumar) said the latest study showed that the ancient genome, Rabat ancient culture Yuezhi people in addition to containing Iran's agricultural population, Anatolia In addition to the genetic components of the farming populations and Eurasian steppe herders, there are also a small amount of genetic components of hunting-gatherer related populations in Western Europe, East Asia, and South Asia
Zhong ASTRI ASTRI Further research found that although compared with the Bronze Age population in the region, the Rabat ancient population in the Iron Age contained more genetic components of the late Bronze Age Eurasian steppe herders, and there was no population turnover related to the genetic components of the Eurasian steppe herders.
In addition, unlike the Bronze Age population in this region, which contained a higher proportion of the genetic components of the Iranian agricultural population, the Iron Age Rabat ancient population contained less genetic components from the Iranian agricultural population, while it contained more genetic components from the Anatolian agricultural population
Regarding the Guishuang culture, this study found that the ancient population of Erhalakat metabolized by ironware mainly contained genetic elements related to Iranian agricultural population, Anatolian agricultural population, and Eurasian steppe herders, as well as a small amount of western Europe and East Asia.
In the Iron Age, the agricultural population was closely connected with the grassland herders
In the Iron Age, the agricultural population was closely connected with the grassland herders Fu Qiaomei concluded that the results of this ancient genome study showed that in the Uzbekistan region of the Iron Age, the connection and communication between the Iranian agricultural population and the Eurasian steppe herders became closer
She believes that although the cultural features of the Rabat cemetery (relatively single) tombs, funeral customs and other cultural features are different from those of the Sher Khalakat cemetery (multiple burial forms and burial customs, and diverse cultures), there are relatively different groups of people involved.
The latest paleogenomic research also found that in the Iron Age, there was a close genetic connection between the Yue culture-related people represented by the Rabat Cemetery and the Guishuang culture-related people represented by the Sher Harakat Cemetery.
As a successful practice of the Chinese team leading the study of population evolution in regions outside East Asia, this study will play an important role in highlighting and enhancing the international influence and discourse power of Chinese paleogenome research
