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.

Subadult health and disease in prehistoric Tonga, Polynesia

This article focuses on the differential diagnosis of pathologic lesions recorded on the limbs and crania of 17 subadults from two pre-European burial mounds in Tonga, western Polynesia. All affected subadults were between the ages of 6 months and 3 years at death. The lesions described consist primarily of subperiosteal new bone deposition on the limbs and endocranial surface. However, the presence of cribra orbitalia in a number of individuals indicates concurrent iron-deficiency anaemia. A differential diagnosis of haematogenous osteomyelitis, congenital syphilis, yaws, scurvy, hypervitaminosis A, trauma, Caffeys disease, and iron-deficiency anaemia is discussed. It was concluded that the most likely cause for the lesions observed is a synergistic relation between infection (weanling diarrhoea, yaws) and metabolic disease (scurvy and possibly hypervitaminosis A). Trauma is not ruled out as contributing to the development of some pathologic lesions. It is concluded that, in the Pacific Islands at least, multiple causes for skeletal pathology in subadults should be considered rather than a single aetiology.

Complete mitochondrial DNA genome sequences from the first New Zealanders

The dispersal of modern humans across the globe began ∼65,000 y ago when people first left Africa and culminated with the settlement of East Polynesia, which occurred in the last 1,000 y. With the arrival of Polynesian canoes only 750 y ago, Aotearoa/New Zealand became the last major landmass to be permanently settled by humans. We present here complete mitochondrial genome sequences of the likely founding population of Aotearoa/New Zealand recovered from the archaeological site of Wairau Bar. These data represent complete mitochondrial genome sequences from ancient Polynesian voyagers and provide insights into the genetic diversity of human populations in the Pacific at the time of the settlement of East Polynesia.

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.

The First New Zealanders: Patterns of Diet and Mobility Revealed through Isotope Analysis

Direct evidence of the environmental impact of human colonization and subsequent human adaptational responses to new environments is extremely rare anywhere in the world. New Zealand was the last Polynesian island group to be settled by humans, who arrived around the end of the 13th century AD. Little is known about the nature of human adaptation and mobility during the initial phase of colonization. We report the results of the isotopic analysis (carbon, nitrogen and strontium) of the oldest prehistoric skeletons discovered in New Zealand to assess diet and migration patterns. The isotope data show that the culturally distinctive burials, Group 1, had similar diets and childhood origins, supporting the assertion that this group was distinct from Group 2/3 and may have been part of the initial colonizing population at the site. The Group 2/3 individuals displayed highly variable diets and likely lived in different regions of the country before their burial at Wairau Bar, supporting the archaeological evidence that people were highly mobile in New Zealand since the initial phase of human settlement.

First bioarchaeological evidence of probable scurvy in Southeast Asia: Multifactorial etiologies of vitamin C deficiency in a tropical environment

This paper presents the first bioarchaeological evidence of probable scurvy in Southeast Asia from a six-year-old child at the historic-era site of Phnom Khnang Peung (15-17th centuries A.D.) in the Cardamom Mountains, Cambodia. Examination of skeletal material shows evidence consistent with scurvy - specifically, abnormal porosity on the greater wings of the sphenoid bone and hard palate, and vascular impressions on the ectocranial surface of the frontal bone and maxillary alveolar bone. In addition, this individual has evidence of cribra orbitalia indicative of anemia. Although a nutritionally linked etiology is the most common cause of scurvy, a number of other factors influencing ascorbic acid levels need to be considered in an environment with sufficient vitamin C potentially available in the diet. Assessing the environmental evidence, the possibility of a number of interrelated factors contributing to the development of scurvy in this individual seems the most plausible explanation. Factors affecting vitamin C levels may have included social aspects of food allocation or choice of food, genetic predisposition, anemia, pathogens, and nutrient malabsorption.

Possible Gouty Arthritis in Lapita-Associated Skeletons from Teouma, Efate Island, Central Vanuatu

The discovery of the ca. 3,000‐year‐old Lapita cemetery site of Teouma on Efate Island, Vanuatu, has for the first time provided the opportunity for biological anthropologists to begin to address issues of health at a population level in these previously elusive people. Macroscopic observation and radiography have revealed the occurrence of erosive arthritis in seven individuals from Teouma. Differential diagnosis of the disease causing the lesions includes gout, rheumatoid arthritis, and the seronegative spondyloarthropathies. On the basis of the type and pattern of lesions and the epidemiology of erosive arthropathies in the Pacific Islands, a diagnosis of gout may be tentatively proposed, giving a crude prevalence rate of 35% (n = 7/20) in the sample. The occurrence of gout in a skeletal sample of possible Polynesian ancestors provides tantalizing clues to the antiquity of a disease which is a significant modern health problem in some Pacific Island populations.

Biocultural Interpretations of Trauma in Two Prehistoric Pacific Island Populations from Papua New Guinea and the Solomon Islands

Two Pacific Island skeletal samples originating from the inland site of Nebira, Papua New Guinea (1230-1650) and a coastal site on the small island of Taumako, Solomon Islands (1530-1698) were examined for evidence of skeletal trauma using a biocultural approach. The types of trauma identified were cranial trauma, postcranial fractures, and piercing and sharp force trauma. Both samples exhibit trauma (Nebira, n = 9/28, 32.1%; Taumako, n = 17/133, 12.8%). Postcranial fractures are significantly higher in males from Nebira (Fisher Exact P value = 0.025). The prevalence of cranial trauma (n = 6/28, 21.4%) is significantly higher in Nebira individuals (Fisher Exact P value = 0.007). There is no conclusive evidence of piercing trauma at Nebira unlike Taumako, which has four individuals with evidence of piercing or sharp force trauma. Both samples show evidence of interpersonal violence and warfare. The results suggest the environment may have contributed to the pattern of trauma at these sites. These patterns are discussed within their cultural and environmental contexts.

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.
