The second Qinghai -Tibet Science Examination "Geological Evidence and Human Adaptation" special exchange meeting was held -human beings spread to the plateau to the settlement experience of five stages

On the 8th, the seventh "Geological Evolution and Human Adaptation" special exchanges in the second Qinghai -Tibet Science and Tibetan science and examination series of academic exchanges was held at Peking University. Representatives of the Ministry of Science and Technology, the Chinese Academy of Sciences, Peking University, the Ministry of Propaganda and the Central Propaganda Department attended the meeting.

Academician Chen Figu, director of the Qinghai -Tibet Plateau Institute of the Chinese Academy of Sciences, introduced that through investigation and excavation of the Qinghai -Tibet Plateau archeological sites and the analysis of lake deposits and historical documents, the five stages of human beings spread to the plateau to settle in the plateau The physiological adaptation of the plateau in the late world; modern Homo sapiens opened an exploration of the hinterland of the plateau from 40,000 to 30,000 years ago; during the warmth of the climate since the last ice period, the crowd of fine stone spreads to the plateau in a large range; millet works The agricultural population entered the low altitude valley area of ​​the east of Plateau 5200 years ago, and began to settle in the altitude area of ​​3,000 meters in the east of the plateau 4800 years ago; 3500 years ago, Mai Zuo's introduction and animal husbandry economic development helped the crowd to settle in high -altitude areas.

Professor Song Changqing, Minister of Geographical Sciences of Beijing Normal University, said that through the analysis of the ethnic space behavior of the Qinghai -Tibet Plateau in the past 2000, as well as the analysis of important events such as conflict with the eastern part of China The more stable and powerful forces; during the temperature fluctuations, some ethnic groups will move out of the Qinghai -Tibet region; during the cold period, the Qinghai -Tibet ethnic groups that are mainly from the East will set up a separatist regime on the edge of the Qinghai -Tibet Plateau.

Focusing on the latest fossil evidence and research results obtained from the scientific examination, researcher Deng Tao, director of the Institute of Ancient Research Institute of the Chinese Academy of Sciences, introduced many mammals, fish, birds and plants in different geological periods. In the process of spreading around the world, the Qinghai -Tibet Plateau has become an important evolution hub for modern biodiversity. The strong dragon up in the new generation of the Qinghai -Tibet Plateau has profoundly affected the climate environment and ecosystems of the plateau and the edge of the edge, which has a strong driver on the evolution of creatures. Ancient human "shuttle" incidents of ancient humans who have many directions between Asia, Europe, and Africa have revealed that Asia is the "exchange" of human evolution, and reveals the evolution of ancient humans in Asia through spectrum research.

Professor Zhang Jinjiang of the School of Earth and Space Sciences of Peking University said that the research team revolved around the key structure sectors such as the Dunhuang Basin, the Alfin and Beishan Structure Belt, and the Sanwei Mountain Fracture. The distribution map uses the material analysis method to explain the coordinated role of the Qinghai -Tibet Plateau construction activities and the evolution of ancient lakes, and reveals the desertification process of the northeast of the Qinghai -Tibet Plateau in the newly -New Tibetan plateau.

According to reports, in the past five years, the second Qinghai -Tibet science examination has adhered to the joint research of humanities and natural sciences, attached importance to the protection and inheritance of cultural heritage, and in -depth influence of the continuation of the geographical environment on the formation of historical and culture. The "world roof" was portrayed into the evolution process, rewritten the history of the evolution of high -cold civilization, and explained the evolution pattern of the Chinese nation.
