The authors compare pottery assemblages in the Marianas and the Philippines to claim endorsement for a first human expansion into the open Pacific around 1500 BC. The Marianas are separated from the Philippines by 2300km of open sea, so they are proposing an epic pioneering voyage of men and women, with presumably some cultivated plants but apparently no animals. How did they manage this unprecedented journey?

We have used electron probe microanalysis to examine Southeast Asian nephrite (jade) artifacts, many archeologically excavated, dating from 3000 B.C. through the first millennium A.D. The research has revealed the existence of one of the most extensive sea-based trade networks of a single geological material in the prehistoric world. Green nephrite from a source in eastern Taiwan was used to make two very specific forms of ear pendant that were distributed, between 500 B.C. and 500 A.D., through the Philippines, East Malaysia, southern Vietnam, and peninsular Thailand, forming a 3,000-km-diameter halo around the southern and eastern coastlines of the South China Sea. Other Taiwan nephrite artifacts, especially beads and bracelets, were distributed earlier during Neolithic times throughout Taiwan and from Taiwan into the Philippines.Austronesian languages ͉ electron probe microanalysis ͉ nephrite trade ͉ Southeast Asian archaeology ͉ Taiwan

This cranio-morphometric study emphasizes a “two-layer model” for eastern Eurasian anatomically modern human (AMH) populations, based on large datasets of 89 population samples including findings directly from ancient archaeological contexts. Results suggest that an initial “first layer” of AMH had related closely to ancestral Andaman, Australian, Papuan, and Jomon groups who likely entered this region via the Southeast Asian landmass, prior to 65–50 kya. A later “second layer” shared strong cranial affinities with Siberians, implying a Northeast Asian source, evidenced by 9 kya in central China and then followed by expansions of descendant groups into Southeast Asia after 4 kya. These two populations shared limited initial exchange, and the second layer grew at a faster rate and in greater numbers, linked with contexts of farming that may have supported increased population densities. Clear dichotomization between the two layers implies a temporally deep divergence of distinct migration routes for AMH through both southern and northern Eurasia.

This study presents the first direct evidence of millet cultivation in Neolithic southeast coastal China. Macroscopic plant remains and phytoliths, together with direct accelerator mass spectrometry (AMS) radiocarbon dates on crops, have shown that both foxtail millet and broomcorn millet were cultivated with rice in the Huangguashan and Pingfengshan sites in Fujian province around 4000-3500 cal. BP. Ratios of different parts of crop remains revealed that crop processing activities such as dehusking and sieving were conducted within the site and thus demonstrated the local production of these crops. The new data, especially the discovery of foxtail millet and broomcorn millet, have greatly changed the current knowledge about the ancient distribution of millet in South China and have now identified southeast China among the potential source-region of Neolithic crops transported overseas to Taiwan and Island Southeast Asia. This study further draws a potential dispersal route of Austronesian languages and people from southern China through Taiwan throughout Southeast Asia.

New research into the Neolithic of Island Southeast Asia is broadening the old models and making them more diverse, more human – more like history: people and animals can move through the islands in a multitude of ways. The domestic pig is an important tracker of Neolithic people and practice into the Pacific, and the authors address the controversial matter of whether domestic pigs first reached the islands of Southeast Asia from China via Taiwan or from the neighbouring Vietnamese peninsula. The DNA trajectory read from modern pigs favours Vietnam, but the authors have found well stratified domestic pig in the Philippines dated to c. 4000 BP and associated with cultural material of Taiwan. Thus the perils of relying only on DNA – but are these alternative or additional stories?

According to direct evidence from archaeology and supporting evidence from comparative linguistics, the Neolithic cultures of the Yangtze alluvial plain played a significant role in the origins of rice cultivation and agricultural populations in East and Southeast Asia. The ultimate results of these developments, according to many authorities, were the dispersals of Austroasiatic and Austronesian-speaking peoples into Mainland and Island Southeast Asia. New archaeological discoveries suggest that some of the earliest pottery in the world also occurred in southern China. Therefore, the historical significance of this region cannot be overlooked. This paper provides a brief review of cultural developments and settlement histories in southern China from the early Neolithic (c. 11,000–8000 b.c .) to the terminal Neolithic (2000 b.c .). Geographically, we examine the middle and lower Yangtze alluvial plain, the Lingnan (southern Nanling Mountains) and Fujian region, and the Yungui Plateau of southern China. Against the backdrop of the waxing and waning of Neolithic cultures in the Yangtze Valley we plot the spread of material culture, rice farming and animal domestication out of the Yangtze region to the Lingnan-Fujian region and the Yungui Plateau, and later into Taiwan and Southeast Asia. This study suggests that the origins of rice agriculture and the process of farming dispersal were more complicated than previously assumed.
