| Research Abstract |
In debates on the population origin of Southeast Asia, it has been advocated that Southeast Asia was initially occupied by an "Australo-Melanesian" population that later underwent substantial genetic admixture with East Asian immigrants from Southern China associated with the spread of agriculture from the Neolithic period onwards. On the contrary, some recent researchers insist that recent Southeast Asians represent the direct lineal descendants of a prehistoric indigenous population without any intensive admixture with East Asians until the present time. This study undertook analyses of dental and cranial morphology to test the validity of these contrastive hypotheses. Dental characteristics analyses demonstrate close affinities between recent Australo-Melanesian samples and pre-Neolithic Southeast Asia such as the Hoabinhian/Mesolithic series from Southeast Asia. These specimens are considered to be members of a population that originated in late Pleistocene Sundaland and are believed to share common ancestors with Australian Aboriginal people. The dental characteristics of the modern inhabitants of most of Southeast Asia exhibit a mixture of traits associated with Northeast Asians and Australo-Melanesians, suggesting that these people have been genetically influenced by immigrants from Northeast Asia. In the Japanese Islands, gene flow from Northeast Asia also appears to have occurred to a certain extent in the Holocene Jomon people. The morphological analyses of Late Pleistocene to early Holocene human skeletons from Moh Khiew Cave in Thailand, Gua Gunung in Malaysia and Hoabinhian sites in Vietnam resulted that these remains represent a member of the Sundaland population during the Late Pleistocene, who may share common ancestry with the present-day Australian aborigines and Melanesians.
