Abstract: The human skeletons studied in this article were buried ca.5000Bp and unearthed at Guangrao Neolithic Site of Shandong. We observed 61 human skulls of them in eight minor skeletal variants and calculated the frequency of their occurrence. The results from the cluster analysis and the principle component analysis based on the mean measure of divergence (MMD) of eight groups of Mongoloids show that the Guangrao skeletons belong to the East Asian Mongoloid group and we also find that mylohyoid bridge, double hypoglossal canal and supraorbital foramen contribute more to differenti- ate the geographical types of Mongoloids.
