On May 15, the American Journal of Science published online the research paper "ancient DNA indicators human population shifts and accommodation in northern and southern China" completed by Fu qiaomei, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences China, from the perspective of genetics, has solved some puzzles on the major academic issues of prehistoric population pattern and migration and mixing in the north and south of China. It is an important scientific discovery and research achievement on the genetic characteristics, gene exchange and migration fusion of ancient populations in China and East Asia. The relevant research results show the genetic and evolutionary history of prehistoric population in China, and provide important information on the genetic, evolutionary and adaptive aspects of prehistoric human in the East, especially in China.
This paper is the first to officially publish the results of large-scale analysis of prehistoric human genome in North and South China, which has made important contributions to the exploration of Chinese ethnic group and its culture and the revision of the evolution model of South East Asia population. In terms of the origin of the Chinese nation, it is found that the continuous evolution of the main population in China and East Asia is the main theme. The ancient groups in the north and south of China have been divided as early as 9500 years ago. At least 8300 years ago, the process of the integration and cultural exchange between the north and the South began. 4800 years ago, the trend of strengthening appeared, and it is still continuing. In terms of the revision of the evolution model of the population in the south of East Asia, it is clear that the ancient southern population in Fujian and its surrounding areas 8400 years ago does not belong to the "first level" ancestor population, that is, the ancient population from South Asia and the Pacific Islands. In fact, they are the ancestral sources of the South Island language group (now mainly living in Taiwan, Pacific Islands and other places); there are genetic connections between the entire East Asian coastal groups, which provides the genetic basis for revising the "two-tier hypothesis" of the origin of the ancient groups in the region, and provides important evidence for the agricultural language communication model and related research. By improving and innovating the ancient DNA technology, this achievement is the first to obtain the nuclear genome of people in the south of China, which makes it possible to study the genetic information of people in East Asia on a large scale, and the related technology has an important application prospect.
this academic achievement is the important breakthrough made The important findings are of great academic value and social significance for the effective protection and utilization of human genetic resources and information, and for the exploration project of Chinese nation and Chinese civilization.
In recent years, many achievements have been made in the study of ancient human genetic evolution in Southeast Asia, Siberia and other places adjacent to East Asia. But up to now, East Asia, especially the South and north of China, as the origin center of rice farming and millet farming respectively, little information about prehistoric human genome is known. Previously, Fu qiaomei's team's research on the tianyuandong people 40000 years ago revealed the diversity of prehistoric populations in East Asia and the complexity of their genetic history, opening up the situation for the study of the ancient genome of the East Asian population, and also stimulating the urgent need for a series of sampling studies on the ancient human samples from different periods and regions in East Asia.
In order to solve this problem, Fu qiaomei's team cooperates with the Institute of Archaeology of Fujian Museum, Pingtan International South Island language group research institute, Fujian Longyan and Zhangping Museum, Shandong Institute of Archaeology and cultural relics, Jilin University, Shandong University, Shandong Museum, Peking University, Inner Mongolia Institute of cultural relics and Archaeology, Northwest University and other units to jointly develop Youguan The ancient DNA technology of linkage successfully captured and sequenced the genomes of 25 individuals 9500-4200 years ago and 1 individual 300 years ago from 11 sites in Shandong, Inner Mongolia and southern Fujian, adjacent to Liangdao and suogang in northern China (Fig. 1a and b). This provides important genetic evidence for the study of the migration and evolution history of the ancient populations in East Asia, especially the modern people under the framework of large space-time. It is also the first systematic paleogenomic study of the largest time span for the population in North and South China.
The origin of ancient DNA in the South and north of East Asia
A survey of prehistoric population patterns in East Asia reveals the genetic differences, fusion process and main body continuity of ancient populations in North and South China
The institute involves early Neolithic population samples, including 7 individuals from 5 sites (Bian Dong, Xiao Jing Shan, Xiao Gao, Bo Shan, Yu Min) in northern Shandong and Inner Mongolia, 9500-7700 years ago, and 3 individuals from 2 sites (Qihe Dong, Liang Dao) in Southern Fujian and Taiwan Strait, 8400-7600 years ago. By studying the genomes of these populations, it is found that the population along the the Yellow River River Valley to the eastern Siberia steppe carries at least 9500 years ago a component of the ancient North population represented by the Neolithic Shandong individuals (Figure 3). The mainland China coast and Taiwan Strait Islands have a Neolithic Fujian and its adjacent islands since at least 8400 years ago. The body is the representative composition of ancient southern people (Fig. 1c and D), and the two components are quite different (Fig. 3a). However, over time, the differences and differentiation between the populations in the north and the south of the East Asian continent have gradually decreased (FIG. 4A), suggesting that since the Neolithic era, the north and the South
