摘要
Genetic distances were calculated for Han subpopulations in different provinces, cities and au-tonomous regions and ethnic minorities in China by using gene frequency data of 38 loci, and genetic trees were con-structed. The results showed that, among both Han and ethnic minorities, there were two types, i.e. southern and northern Mongoloids, with Yangtze River as boundary. Therefore, both African origin theory and local origin theory about the modern man should answer the question; when did these two types separate and how did they develop. This paper also conclusively proved genetically that the Han subpopulations in different regions are genetically close to the lo-cal ethnic minorities, which indicates that much blood of ethnic minorities has mixed into Han, at the same time, some blood of Han also has mixed into the local ethnic minorities.
