| Research Abstract |
An excavations at Hang Cho site in northern Vietnam resulted in the discovery of an early Holocene human skeletons in a relatively good state of preservation. The cultural remains refer to these human remains pre-ceramic Hoabinian period. An AMS radiocarbon date on the tooth sample gave a result of 10,450BP. In debates on the population history of Southeast Asia, it has been repeatedly advocated that Southeast Asia was occupied by an indigenous people akin to present-day Australo-Melanesians prior to an expansion of migrants from North-East Asia into this area. Morphometric analyses were undertaken to test the validity of this hypothesis, and demonstrate that the Hang Cho specimen resembles the Late Pleistocene Australians, suggesting that the Hang Cho skeleton represents a descended member from the Sundaland population during the Late Pleistocene, who may share common ancestry with the present-day Australian aborigines and Melanesians. The excavation of Man Bac site (c.3800BP) in Ninh Binh Province, Northern Vietnam, discovered the large mortuary assemblage. A total of 31 inhumations were recovered during our 2005's excavation. The ratio of children to adults was two to three, indicating unordinary high infant mortality of the Man Bac people. Although a few individuals have the low and wide faces with robust crania common to those of the pre-Neolithic Hoabinhian people, many others bear the long and flat faces. The specimens of the later type have close affinities in the cranial metrics to the Jiangnan people of the Zhou and the Former Han periods in Yangzi Basin, and to the Yayoi migrants in Japan, as well. These findings suggest the existence of initial immigrants from South China, who settled in northern Vietnam. The Man Bac skeletons support the "immigration hypothesis with farming dispersals" in Southeast Asia advocated by Bellwood and others.
