Researchers from the Chinese Academy of Sciences, in a paper published in the journal Science, used genomic data to analyze the pattern and migration and mixing of prehistoric populations in the north and south of China. The researchers collected and sequenced the genomes of 25 9,500-4200-year-old individuals and one 300-year-old individual at 11 sites in Shandong, Inner Mongolia and Fujian in the south, adjacent to Liangdao and Lock harbor.
They found that in the population along the Yellow River basin up to the eastern Siberian grasslands, at least 9,500 years ago, there has been a group of ancient northerners represented by Neolithic Shandong individuals, while the people of the coastal and Taiwan straits in mainland China have carried a group of ancient southerners represented by Neolithic Fujian and its adjacent islands since at least 8,400 years ago, and the two components are very different.

“That is to say, as early as 9,500 years ago, the population of china’s north and south was divided, ” said Fu Qiaomei, the head of the study. Over time, however, the degree of inter-ethnicity and division between the north and south began to narrow gradually, a change that suggests that since the Neolithic period, there has been frequent migration and mixing between the north and the south. “
