The Yangtze River Delta is the best-known homeland of wet-rice agriculture. From the Middle Neolithic, rice farming expanded from the Yangtze region to both the north and the south. However, poor preservation of ancient human skeletal remains in the region has meant that the population history of these expansions has not been fully understood. In order to clarify the ancestry of early wet-rice farmers in East Asia, we conducted a cranial morphometric analysis and comparison of a Middle Neolithic skeletal assemblage excavated from the Guangfulin site, Shanghai. The results of bivariate and multivariate analyses showed that: (1) Neolithic wet-rice farmers from the lower Yangtze retained local morphological characteristics, but were nevertheless morphologically more similar to Neolithic and later populations in northern China, which was home to early millet farmers, than to Neolithic populations in south China; and (2) Neolithic and later agricultural populations in East Asia were morphologically homogeneous compared to pre-Neolithic hunter-gatherer groups even though the area occupied by both was equally vast. These results suggest, respectively, that: (1) Middle Neolithic wet-rice farmers in the Yangtze Delta experienced significant gene flow from regions of northern China such as the Central Plains and Shandong even though there is currently no evidence that millet cultivation itself had yet reached the delta region; and (2) Neolithic populations resulting from interaction between the Yangtze Delta and northern China dispersed widely across much of East Asia including the Japanese archipelago together with the spread of wet-rice agricultural technologies. These two proposals are paralleled by recent stable isotope analyses using tooth enamel and bone collagen, as well as archaeological evidence from Shandong. Finally, a facial approximation was conducted using a cranium (M252) excavated from Guangfulin for the purpose of visually expressing the results of this study.

In this study, nine nonmetric cranial traits were recorded for ancient human remains excavated at early prehistoric (the late Pleistocene, early Holocene, and Pre-Pottery Neolithic) and late prehistoric (the Neolithic and early Iron age) archeological sites in northern Vietnam. The comparative samples consist of prehistoric and early historic crania from the lower Yangtze River basin, together with recent cranial series from Vietnam, Thailand, South China, and Australia. The results, based mainly on the measure of divergence, are as follows: (1) the early prehistoric northern Vietnam group is distinct from the subsequent inhabitants of northern Vietnam and neighboring populations; (2) the cranial series of northern Vietnam and the surrounding region from the late prehistoric to recent times through early historic period exhibit relative homogeneity, suggesting population continuity; (3) the recent Han Chinese from southern China, one of the possible representatives of East Asians, are relatively distant from all groups from the prehistoric age onwards; and (4) a clear separation of Aboriginal Australians from all the comparative samples, including the early prehistoric northern Vietnamese, is evident. These findings suggest partial support for the two opposing hypotheses, i.e. the two-layer model and the regional-continuity model, for the population history of Southeast Asians, at least, in the northern Vietnamese region. This may be further compatible with the recent hypothesis for modern human dispersals: an earlier out-of-Africa expansion of Australians than other contemporary Eurasians including Southeast Asians.
