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’.

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.

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.

Chickens ( Gallus gallus domesticus ) from the Americas have long been recognized as descendants of European chickens, transported by early Europeans since the fifteenth century. However, in recent years, a possible pre-Columbian introduction of chickens to South America by Polynesian seafarers has also been suggested. Here, we characterize the mitochondrial control region genetic diversity of modern chicken populations from South America and compare this to a worldwide dataset in order to investigate the potential maternal genetic origin of modern-day chicken populations in South America. The genetic analysis of newly generated chicken mitochondrial control region sequences from South America showed that the majority of chickens from the continent belong to mitochondrial haplogroup E. The rest belongs to haplogroups A, B and C, albeit at very low levels. Haplogroup D, a ubiquitous mitochondrial lineage in Island Southeast Asia and on Pacific Islands is not observed in continental South America. Modern-day mainland South American chickens are, therefore, closely allied with European and Asian chickens. Furthermore, we find high levels of genetic contributions from South Asian chickens to those in Europe and South America. Our findings demonstrate that modern-day genetic diversity of mainland South American chickens appear to have clear European and Asian contributions, and less so from Island Southeast Asia and the Pacific Islands. Furthermore, there is also some indication that South Asia has more genetic contribution to European chickens than any other Asian chicken populations.

The essays in this special section on early settlement in Island Southeast Asia may be puzzling to readers of Antiquity who are uninitiated to the ways and concerns of archaeologists working in the Pacific. Some of these authors appear almost reluctant to draw conclusions from the evidence they survey. Others champion their own interpretations unequivocally. What is going on here?It may be, as some say, that academics are by nature a quarrelsome lot. Even so, why is the Lapita cultural complex ‘ever a hot source of debate’ (Bellwood & Koon, above, p. 613)? The essays published here may lack the direct cantankerousness of face-to-face confronat international symposia and professional meetings, but they reinforce the suggestion made in Antiquity a year ago that archaeologists in the Pacific today have come to a crossroads where we often find ourselves talking past each other because we are no longer in general agreement on what is interesting about Pacific prehistory and why (Terrell 1988).

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.

Early Farming

Several recent articles in Antiqui (Barker et al. 201 la; Hung et al. 2011; Spriggs 2011), discuss the validity of, and revise, portrayals of an Austronesian farming-language dispersal across Island Southeast Asia (ISEA) during the mid-Holocene (approximately 4000-3000 years ago) . In conventional portrayals of the Austronesian dispersal hypothesis (e.g. Bellwood 1984/85, 1997, 2002, 2005; Diamond 2001; Diamond & Bellwood 2003) , and its Neolithic variant (e.g. Spriggs 2003, 2007), farmer-voyagers migrated out of Taiwan approximately 4500-4000 cal BP to colonise ISEA from 4000 cal BP (Bellwood 2002) and the Mariana Islands and Palau by c. 3500-3400 cal BP (Hung et al. 201 1). The descendants of these voyagers subsequently established the Lapita Cultural Complex in the Bismarck Archipelago by c. 3470-3250 cal BP (Kirch 1997; Spriggs 1997) and became the foundational cultures across most of the Pacific from c. 3250-3100 cal BP (Kirch 2000; Addison & Matisoo-Smith 2010; dates for Lapita in Denham et al. 2012). A major problem with this historical metanarrative is the absence of substantial archaeological evidence for the contemporaneous spread of farming from Taiwan (Bulbeck 2008; Donohue & Denham 2010; Denham 2011 ).
