Abstract: The morphological traits of teeth from Neolithic Miaozigou site in Inner Mongolia were observed with ASU Dental Anthropology System proposed by Dr. Turner. The frequencies of morphological traits of Miaozigou teeth show greater similarities with those of NE Asians, especially Anyang of Shang Dynisty than with SE Asians. The multivariate statistics of MMD and cluster anlysis indicate that the people of Miaozigou has closer affinities with NE Asian populations. The authors believe that the present study supports the two-fold divisions of Sinodonty and Sundadonty among East Asian peoples. But some more researches are needed to reveal the mechanism of the above result.
