The Teouma Lapita site and the early human settlement of the Pacific Islands

The Teouma site, on Efate in central Vanuatu, was uncovered during quarrying in 2003 and has proved to be one of the most significant discoveries to date for the colonisation of Remote Oceania. Not only did it bring to light a fine assemblage of the famously diagnostic Lapita ceramics, but a cemetery of more than 25 individuals along with the pots. The skeletons offer an opportunity to investigate the origins of the �Lapita people� who first appeared in the Bismarck archipelago around 3300 years ago and rapidly moved through island Melanesia and Western Polynesia over the next few centuries.

Lapita migrants in The Pacific's oldest cemetery: isotopic analysis at Teouma, Vanuatu

Teouma, an archaeological site on Efate Island, Vanuatu, features the earliest cemetery yet discovered of the colonizers of Remote Oceania, from the late second millennium B.C. In order to investigate potential migration of seventeen human individuals, we measured isotopes of strontium (87Sr/86Sr), oxygen (δ18O), and carbon (δ13C), as well as barium (Ba) and strontium (Sr) concentrations, in tooth enamel from skeletons excavated in the first two field seasons. The majority of individuals cluster with similar isotope and Ba/Sr ratios, consistent with a diet of marine resources supplemented with plants grown on the local basaltic soils. Four outliers, with distinctive 87Sr/86Sr and δ18O, are probably immigrants, three of which were buried in a distinctive position (supine, with the head to the south) with higher Ba/Sr and δ13C, consistent with a terrestrial, nonlocal diet. Among the probable immigrants was a male buried with the crania of three of the locally raised individuals on his chest.

Genomic insights into the peopling of the Southwest Pacific

The appearance of people associated with the Lapita culture in the South Pacific around 3,000 years ago marked the beginning of the last major human dispersal to unpopulated lands. However, the relationship of these pioneers to the long-established Papuan people of the New Guinea region is unclear. Here we present genome-wide ancient DNA data from three individuals from Vanuatu (about 3,100–2,700 years before present) and one from Tonga (about 2,700–2,300 years before present), and analyse them with data from 778 present-day East Asians and Oceanians. Today, indigenous people of the South Pacific harbour a mixture of ancestry from Papuans and a population of East Asian origin that no longer exists in unmixed form, but is a match to the ancient individuals. Most analyses have interpreted the minimum of twenty-five per cent Papuan ancestry in the region today as evidence that the first humans to reach Remote Oceania, including Polynesia, were derived from population mixtures near New Guinea, before their further expansion into Remote Oceania. However, our finding that the ancient individuals had little to no Papuan ancestry implies that later human population movements spread Papuan ancestry through the South Pacific after the first peopling of the islands.

Megafaunal meiolaniid horned turtles survived until early human settlement in Vanuatu, Southwest Pacific

Meiolaniid or horned turtles are members of the extinct Pleistocene megafauna of Australia and the southwest Pacific. The timing and causes of their extinction have remained elusive. Here we report the remains of meiolaniid turtles from cemetery and midden layers dating 3,100/3,000 calibrated years before present to approximately 2,900/2,800 calibrated years before present in the Teouma Lapita archaeological site on Efate in Vanuatu. The remains are mainly leg bones; shell fragments are scant and there are no cranial or caudal elements, attesting to off-site butchering of the turtles. The new taxon differs markedly from other named insular terrestrial horned turtles. It is the only member of the family demonstrated to have survived into the Holocene and the first known to have become extinct after encountering humans.

New Extinct Mekosuchine Crocodile from Vanuatu, South Pacific

Abstract We describe a new species of crocodile (Reptilia: Crocodyloidea: Mekosuchinae) from a maxilla recovered at the Arapus archaeological site, on the island of Efate, Vanuatu, South Pacific. As with mekosuchine species in New Caledonia and Fiji, Mekosuchus kalpokasi sp. nov. was a small, possibly terrestrial carnivore that is now extinct. The differences between the Efate specimen and previously described species of Mekosuchus warrant recognition of a new species. Based on its association with Efates earliest known human inhabitants, dating approximately 3000 cal yr B.P., the extinction of M. kalpokasi and other insular mekosuchines may have been anthropogenic. The lack of adequately dated pre-Quaternary and Quaternary vertebrate fossil records from Vanuatu, New Caledonia, and Fiji (as well as other smaller islands) precludes determining the timing and route of dispersal of mekosuchine crocodyloids.

Northern Vanuatu as a Pacific Crossroads: The Archaeology of Discovery, Interaction, and the Emergence of the "Ethnographic Present"

Northern Vanuatu is a significant crossroads region of the Southwest Pacific. This paper outlines current archaeological research being undertaken in the area, focusing on defining initial human settlement there some 3000 years ago and subsequent cultural transformations which led to the establishment of the ethnographic present. The study to date has contributed to a more detailed picture of inter- and intraarchipelago interaction, settlement pattern, subsistence, and cultural differentiation. The research contributes to regional debates on human colonization, patterns of social interaction, and the drivers of social change in island contexts.

Lapita Diet in Remote Oceania: New Stable Isotope Evidence from the 3000-Year-Old Teouma Site, Efate Island, Vanuatu

Remote Oceania was colonized ca. 3000 BP by populations associated with the Lapita Cultural Complex, marking a major event in the prehistoric settlement of the Pacific Islands. Although over 250 Lapita sites have been found throughout the Western Pacific, human remains associated with Lapita period sites are rare. The site of Teouma, on Efate Island, Vanuatu has yielded the largest burial assemblage (n = 68 inhumations) of Lapita period humans ever discovered, providing a unique opportunity for assessing human adaptation to the environment in a colonizing population. Stable isotope ratios (δ13C, δ15N, δ34S) of human bone collagen from forty-nine Teouma adults were analyzed against a comprehensive dietary baseline to assess the paleodiet of some of Vanuatus earliest inhabitants. The isotopic dietary baseline included both modern plants and animals (n = 98) and prehistoric fauna from the site (n = 71). The human stable isotope data showed that dietary protein at Teouma included a mixture of reef fish and inshore organisms and a variety of higher trophic marine (e.g. marine turtle) and terrestrial animals (e.g. domestic animals and fruit bats). The domestic pigs and chickens at Teouma primarily ate food from a C3 terrestrial environment but their δ15N values indicated that they were eating foods from higher trophic levels than those of plants, such as insects or human fecal matter, suggesting that animal husbandry at the site may have included free range methods. The dietary interpretations for the humans suggest that broad-spectrum foraging and the consumption of domestic animals were the most important methods for procuring dietary protein at the site. Males displayed significantly higher δ15N values compared with females, possibly suggesting dietary differences associated with labor specialization or socio-cultural practices relating to food distribution.

A Preliminary Report on Health and Disease in Early Lapita Skeletons, Vanuatu: Possible Biological Costs of Island Colonization

ABSTRACT The human colonization of Near Oceania has an antiquity of over 40,000 years but colonization of Remote Oceania, including Vanuatu, did not begin until around 3200–3100 BP. Just before this time a distinctive form of dentate-stamped pottery known as the Lapita style appeared in the Bismarck Archipelago northeast of the island of New Guinea. The only direct evidence of health in these Remote Oceanic settlers is their skeletal remains, but until recently only small samples of late Lapita skeletons have been found. Here we report the preliminary findings on some aspects of health of the first large sample (36 individuals) of early Lapita-associated skeletons from Teouma, Vanuatu, dated to ca. 3100–3000 BP. Dental health, trauma and degeneration of joints show they were well adapted to the rigors of island life and lived a physically active life while coping with a significant disease burden. The discovery of skeletal remains of pioneer settlers on islands is extremely rare. The Teouma sample provides insights into the possible biological cost of such a colonization and is applicable to other contexts where human migration into virgin landscapes may have demanded biological adaptation to ensure success.

Lapita Burial Practices: Evidence for Complex Body and Bone Treatment at the Teouma Cemetery, Vanuatu, Southwest Pacific

ABSTRACT Excavation of the 3,000-year-old Lapita cemetery of Teouma (Efate, Central Vanuatu) has allowed the first detailed investigation of mortuary practices of these initial colonizers of the Vanuatu archipelago. Focusing on one component of funerary practice: the adult corpse and bone treatment of 25 mortuary contexts recovered at the site during excavations in 2004 and 2005, the present study reveals that beyond a complex procedure common for all the deceased, there is marked diversity of funerary behavior. Utilizing current knowledge and practice regarding the method of field anthropology or archaeothanatology, including the chronology of joint disarticulation sequences, we were able to establish the following practices: treatment of corpses by inhumation in a container—pit or wrappers—not immediately filled with sediment, followed by exhumation of the skull and other bones of the upper part of the skeleton, and secondary deposition of bones, including the cranium. The identified variations reflect particular attitudes toward human remains which might be connected to the social position of the deceased and/or individual choice.

The Pacific's earliest painted pottery: an added layer of intrigue to the Lapita debate and beyond

Lapita pottery, the herald of the settlement of the wider island Pacific, turns out to have been painted with lime and clay, to give a red and white finish over the decorated surface. The find of a pot in Vanuatu, its sherds in different states of deterioration showed why painted Lapita has previously gone unrecognised. The author suggests that it was widespread from 1000 BC and reminds us that pottery was painted in China 7000 years ago.
