Two Layer Model

AbstractTwo distinct population models have been put forward to explain present-day human diversity in Southeast Asia. The first model proposes long-term continuity (Regional Continuity model) while the other suggests two waves of dispersal (Two Layer model). Here, we use whole-genome capture in combination with shotgun sequencing to generate 25 ancient human genome sequences from mainland and island Southeast Asia, and directly test the two competing hypotheses. We find that early genomes from Hoabinhian hunter-gatherer contexts in Laos and Malaysia have genetic affinities with the Onge hunter-gatherers from the Andaman Islands, while Southeast Asian Neolithic farmers have a distinct East Asian genomic ancestry related to present-day Austroasiatic-speaking populations. We also identify two further migratory events, consistent with the expansion of speakers of Austronesian languages into Island Southeast Asia ca. 4 kya, and the expansion by East Asians into northern Vietnam ca. 2 kya. These findings support the Two Layer model for the early peopling of Southeast Asia and highlight the complexities of dispersal patterns from East Asia.

The Caribbean

Many books have been written about the incorporation of the Caribbean region, South Asia, Africa and Latin America into the global economy. Remarkably, few have dealt with Island Southeast Asia or Maritime Southeast Asia as a macro-region. For the Caribbean nations, it has been amply discussed how the legacies of the plantation economies consisted of meagre economic growth and massive unemployment. Conversely, scant attention has been given to the question how societies in Island Southeast Asia were turned into providers of cheap commodities and how this impacted their long-term development prospects. This silence is even more remarkable considering some striking parallels with Caribbean socio-economic trajectories. Today, emigration of millions is the fate of Island Southeast Asia, as it is for the Caribbean region. To break the silence and to invite further discussion I wrote The Making of a Periphery: How Island Southeast Asia Became a Mass Exporter. After reading the review by Dr Aguilar on this book in a previous issue of this journal, I felt that it could be worthwhile to highlight some of the main points of my argument about the peripheral integration of Island Southeast Asia in the global economy. I am grateful to the editors of the International Journal of Asian Studies for granting me the opportunity to do so.

The spread of modern humans into and across Island Southeast Asia and the Pacific represents the earliest confirmed dispersal of humans across a marine environment, and involved numerous associated technologies that indicate sophisticated societies on the move. The later spread of ‘Austronesian’ over the region shows language replacement on a scale that is reminiscent of the period of state-sponsored European colonization, and yet the Austronesian languages present a typological profile that is more diverse than any other large language family. These facts require investigation. This chapter examines the separate, but intertwined, histories of the region. It shows that the dispersal of Austronesian languages, originating in Taiwan, should not be portrayed as a technological and demographic steamroller. This involves discussion of the nature of pre-Austronesian society and language in the south-west Pacific, and the degree to which it has and has not changed following ‘Austronesianization’.

History Of

The Holocene history of Island Southeast Asia (ISEA) is dominated by the ‘Out-of-Taiwan’ hypothesis and derivatives, such as the spread of the Island Southeast Asian Neolithic. According to these ideas, approximately 4500–4000 years ago, farmer-voyagers from Taiwan migrated southward into ISEA to subsequently acculturate, assimilate or displace pre-existing inhabitants. These processes are considered to have produced a consilience between human genetics, Austronesian languages and the archaeological record within ISEA, although recurrent critiques have questioned these putative correspondences. These critiques have proposed that each line of evidence should be independently evaluated and considered, rather than assumed to correspond. In this paper, the authors advocate a fuller engagement with and a deeper understanding of the spatial and temporal processes that structure archaeological, genetic and linguistic distributions within Island Southeast Asia. Geography and history are often marginalized in discussions of the Holocene history of ISEA, yet both are fundamental to the interpretation and reconciliation of multidisciplinary data within the region. These themes are discussed using aphorisms that are designed to be illustrative, namely to promote thought and reflection, rather than to be comprehensive.

Background Considerations

This chapter presents some background considerations relevant to the patterns of language dispersal and diversification in Island Southeast Asia and Oceania. First an overview of languages and language families is given, including three large families—the widely dispersed Austronesian family, the Trans New Guinea (TNG) family in New Guinea, and the Pama-Nyungan family in Australia—as well as many smaller families and isolates. Then the main distinctive typological features of Austronesian languages, New Guinea and Australia are presented. Australia shows surprising structural homogeneity when compared to New Guinea and even to Austronesian. Subsequent sections cover the history of the study of the languages in the region, the history of the region itself, and issues for further research, including the mechanisms in the spread of Austronesian and the language development of New Guinea. The chapter concludes with a brief summary of the chapters in the book regarding the region.

Austronesian languages are spread across half the globe, from Easter Island to Madagascar. Evidence from linguistics and archaeology indicates that the "Austronesian expansion," which began 4-5 thousand years ago, likely had roots in Taiwan, but the ancestry of present-day Austronesian-speaking populations remains controversial. Here, focusing primarily on Island Southeast Asia, we analyze genome-wide data from 56 populations using new methods for tracing ancestral gene flow. We show that all sampled Austronesian groups harbor ancestry that is more closely related to aboriginal Taiwanese than to any present-day mainland population. Surprisingly, western Island Southeast Asian populations have also inherited ancestry from a source nested within the variation of present-day populations speaking Austro-Asiatic languages, which have historically been nearly exclusive to the mainland. Thus, either there was once a substantial Austro-Asiatic presence in Island Southeast Asia, or Austronesian speakers migrated to and through the mainland, admixing there before continuing to western Indonesia.

AbstractThis study reports a cranio-morphometric analysis of female human remains from seven archaeological sites in China, Vietnam and Taiwan that date between 16,000 and 5300 BP. The aim of the analysis is to test the “two-layer” model of human dispersal in eastern Eurasia, using previously unanalysed female remains to balance the large sample of previously-analysed males. The resulting craniometric data indicate that the examined specimens all belong to the “first layer” of dispersal, and share a common ancestor with recent Australian and Papuan populations, and the ancient Jomon people of Japan. The analysed specimens pre-date the expansion of agricultural populations of East/Northeast Asian origin—that is, the “second layer” of human dispersal proposed by the model. As a result of this study, the two-layer model, which has hitherto rested on evidence only from male skeletons, is now strongly supported by female-derived data. Further comparisons reveal that the people of the first layer were closer in terms of their facial morphology to modern Africans and Sri Lankan Veddah than to modern Asians and Europeans, suggesting that the Late Pleistocene through Middle Holocene hunter-gatherers examined in this study were direct descendants of the anatomically modern humans who first migrated out of Africa through southern Eurasia.

Abstract There has been a long-standing debate concerning the extent to which the spread of Neolithic ceramics and Malay-Polynesian languages in Island Southeast Asia (ISEA) were coupled to an agriculturally driven demic dispersal out of Taiwan 4000 years ago (4 ka). We previously addressed this question using founder analysis of mitochondrial DNA (mtDNA) control-region sequences to identify major lineage clusters most likely to have dispersed from Taiwan into ISEA, proposing that the dispersal had a relatively minor impact on the extant genetic structure of ISEA, and that the role of agriculture in the expansion of the Austronesian languages was therefore likely to have been correspondingly minor. Here we test these conclusions by sequencing whole mtDNAs from across Taiwan and ISEA, using their higher chronological precision to resolve the overall proportion that participated in the “out-of-Taiwan” mid-Holocene dispersal as opposed to earlier, postglacial expansions in the Early Holocene. We show that, in total, about 20 % of mtDNA lineages in the modern ISEA pool result from the “out-of-Taiwan” dispersal, with most of the remainder signifying earlier processes, mainly due to sea-level rises after the Last Glacial Maximum. Notably, we show that every one of these founder clusters previously entered Taiwan from China, 6–7 ka, where rice-farming originated, and remained distinct from the indigenous Taiwanese population until after the subsequent dispersal into ISEA.

Established chronologies indicate a long-term ‘Hoabinhian’ hunter-gatherer occupation of Mainland Southeast Asia during the Terminal Pleistocene to Mid-Holocene (45 000–3000 years ago). Here, the authors re-examine the ‘Hoabinhian’ sequence from north-west Thailand using new radiocarbon and luminescence data from Spirit Cave, Steep Cliff Cave and Banyan Valley Cave. The results indicate that hunter-gatherers exploited this ecologically diverse region throughout the Terminal Pleistocene and the Pleistocene–Holocene transition, and into the period during which agricultural lifeways emerged in the Holocene. Hunter-gatherers did not abandon this highland region of Thailand during periods of environmental and socioeconomic change.

The dispersal of Austronesian-speaking farmer-voyagers from Taiwan into Island Southeast Asia (ISEA) and out into the Pacific is one of the great metanarratives of global history. In this chapter, the major lines of multidisciplinary evidence for the “Austronesian” dispersal into ISEA are critically evaluated. Several key points emerge: usage of the term “Austronesian” should be restricted to languages and not be applied to genetic attributes or material culture; the dispersals of genes and Austronesian languages do not correspond within ISEA; and, there is limited evidence for the dispersal of farming across ISEA together with the spread of Austronesian languages from Taiwan. An alternative, multidirectional, distance-decay scenario is advanced for the spread of domesticated animals and plants, cultivation practices, and other material cultural items, in which the inhabitants of ISEA are active participants in the creation of their own history.
