Abstract: The dental morphological traits of the people of Zhanguo period (2000 years BP) unearthed in Longxian of Shaanxi province were observed. The comparisons and statistical analyses show that compared with Neolithic people of north China, the dental morphology of Longxian specimens not only has the typical Mongoloid characteristics but also shows closer similarity with modern north Chinese. The authors believe in the past 10,000 years the physical traits of north Chinese experienced some regular evolution in the direction to the modern north Chinese. This process reflects the trend of microevolution of physical characters of the people of northeast Asia.
