Ancient human genetic maps in the Tianshan area in the Tianshan area

A few days ago, the China Science and Technology Exchange Center organized experts to conduct comprehensive performance evaluation of projects for the national key research and development plan strategic international science and technology innovation cooperation, and the "Ancient Human Genetics Research Research" project undertaken by Northwestern University was successfully passed assessment.

This is the first time that my country's team has led an ancient basis research on foreign regional populations. The expert group discussed the evaluation that the project "achieved the expected goal with high levels of results" and "the breadth and depth of the research of the ancient genome information lack and evolutionary research showed innovation, bringing many new evidence that had not been discovered before. Revisiting the new understanding of the evolution of ancient people in Tianshan. "

The project focuses on genetic evolutionary spectrum

As an important channel for connecting Eastern and Western culture and crowd, the Tianshan Corridor is very well known for the formation characteristics and genetic relationships of people under different archeological cultural relics along the line.

The "Research on Ancient Human Genetics Evolution of Tianshan District" project was appointed by Northwestern University, the molecular biological research team of the ancient vertebrate and the ancient human research institute of the Chinese Academy of Sciences, and the Northwest University Captain of the Central Asian Archaeological Team, and Wang Jianxin The professor's research team jointly completed the units and other units of the Institute of Archeology of the Academy of Academy of Sciences of the Republic of Uzbekistan.

The project focuses on the key scientific issues of "the genetic characteristics and relationship between different cultural people in the Tianshan area". Focusing on the research of ancient genome studies, combined with archeological research and international cooperation, the genetic characteristics of different cultural groups along Tianshan and drawing Tianshan An important breakthrough in the genetic evolution map of the ancient crowd.

Since the project was officially launched in November 2017, the research team has worked together to deeply integrate the research advantages of multi -disciplinary integration of members of the team. It has made breakthroughs in archeological investigation and excavation of archeological investigations and crowd in western Tianshan. Through joint surveys of overseas archeological surveys with foreign cooperation units, the project team has made important progress in the identification and confirmation of cultural relics such as the ancient moon, Guishuang, and Kangju in the western region of Tianshan.

Further ancient DNA analysis shows that there is a close interaction between Yue and Guishuang people, confirming that Uzbekistan is an active area for crowd migration and exchanges, and it has shown a enhanced trend since the bronze to the iron era. This is the first time that my country's team has led an ancient base research on foreign regional populations. The systematic reveals the genetic structure and genetic continuity of the Uzbekistan people from the Bronze Age to the Iron Age. Provide important genetic evidence with integration history.

Fill in regional human gene gaps

In the eastern part of Tianshan, the project team conducted research on human bone samples of more than forty sites of Dongtian Mountain through modern scientific and technological means (carbon 14 testing, isotope analysis, ancient genome capture sequencing, etc.). Hundreds of cases of mitochondria and nuclear genome of the crowd during the historical period fill the gaps of human paleogen in the relevant time and region.

During the study of nuclear -based groups, the project team found that early people in the Bronze Age of northwestern Xinjiang in Dongtian Mountain have shown the characteristics of the ancient people and various surrounding people's genetic composition fusion; Form the genetic structure of the Xinjiang population today.

On the whole, the project's new archeological new data and rich genetic data based on the project have achieved a series of important academic achievements, published 25 academic papers, one publishing academic monograph, and high -influential research results are scientific interpretation of culture along Tianshan. It has provided an important basis with the diversity and integration of the crowd, and further clarified that the Silk Road played an important role in the interactive integration and cultural exchanges and mutual learning of the relevant population of the Silk Road.

The international cooperation model of the project reflects the diversity and innovation. The Chinese team and the Institute of History and Archeology of the Tagikistan Academy of Sciences of the Chinese Team and the Academy of the Academy of Sciences of the Academy of Sciences of the Academy of Sciences of the Academy of Sciences of the Academy of Sciences of the Academy of Sciences have not only achieved major breakthroughs in the joint archeological excavations and research of Central Asia, such as in A large number of joint archaeological surveys were conducted in the Central Asian region of Xitian Mountain, and more than 30 new settlements and urban sites were newly discovered. It was confirmed that the characteristics and distributions of the ancient Yueshi and Kangju culture were confirmed.

Through the field of project expansion cooperation

The project is the first national key research and development plan project undertaken by Northwest University during the "Thirteenth Five -Year Plan" period, and it is also an important part of the archeological work of Northwest University in Central Asia.

The implementation of the project was obtained by the International Cooperation Department of the Ministry of Science and Technology, the China Science and Technology Exchange Center, the Shaanxi Provincial Department of Science and Technology, and the Institute of Ancient Human Research of the Chinese Academy of Sciences, the Institute of Archeology of the Academy of Sciences of the Republic of Uzbekistan, and Xi'an International Protection The center of the Center, the Institute of History and Archeology of the Tajikistan Academy of Sciences, the Uzbekistan National History Museum, the Palace Museum and other units.

The project has launched close cooperation in the aspects of international academic conferences, high -level talent training, and scientific research platform co -construction. Two meetings and two issues of "International Training Class of World Heritage Declaration and Management of the Silk Road", co -construction "China -Central Asian Humans and Environment 'Belt and Road Integration Lab" "Silk Passerby and Animal Orthopedic Chemistry and Five scientific research cooperation platforms including DNA Archeology International Joint Laboratory.

By expanding the field of project cooperation, to promote the sharing and technological promotion of achievements with scientific and technological exchanges, promote the training of talents and platforms in depth cooperation, promote local economic development and ecological construction with heritage protection The interaction of civilization plays an active role in improving my country's international discourse rights and research leadership in the protection and inheritance of the Silk Road Archeology and Cultural Heritage.Northwest University will further strengthen cooperation with relevant units to strengthen cooperation with countries along the Silk Road, promote the construction of existing high -level international cooperation platforms, and lay the foundation for subsequent larger and more diversified international cooperation.(Pangbo)
