A meal on the hoof or wealth in the kraal? Stable isotopes at Kgaswe and Taukome in eastern Botswana

Iron Age sites associated with the Toutswe tradition in Eastern Botswana date between CE 700–1300 and share a variety of settlement patterns, economic features and material culture. The presence of domestic fauna, settlement structures and concentrations of vitrified dung provide archaeological evidence for herding economies. However, due to factors of preservation and past retrieval techniques, evidence for plant remains is still somewhat limited for the Toutswe sites in Botswana. Additionally, archaeological remains such as flora, fauna and material culture often provide only indirect evidence for their contributions to diet. This study provides new evidence for the diet of individuals from the Toutswe tradition. Given the large numbers of animal remains and residues at Toutswe sites, the expectation is that animal domesticates were also an integral part of the diet. Stable isotopic analysis of human remains indicates that even though domestic cattle and sheep occur in great abundance at Toutswe sites, their contribution to the diet may be minimal. The main source of protein for individuals at Kgaswe and Taukome comes from C4 plants such as sorghum and millet and to a lesser extent, animal products. The practice of maintaining large domestic herds for economic and social reasons rather than for primary subsistence in southern Africa today may have its roots in the Iron Age populations of the region.

The Environment and Subsistence of the Early Neolithic Settlement Area at Těšetice-Kyjovice,Czech Republic

This paper presents a reconstruction of environmental conditions and subsistence strategies in the Early Neolithic (6th Millenium BC) settlement area at Tě?etice-Kyjovice (Czech Republic). Our detailed reconstruction of the environment contributes to the unravelling of the genesis and spread of steppes and the formation of secondary anthropogenic forest-free areas in the Holocene in eastern-Central Europe. Mollusc shells, charcoals and plant macroremains were used as on-site evidence of a settlement environment. A relatively warm and dry anthropogenic forest-free area is reconstructed for the immediate vicinity of the Early Neolithic settlement. Communities of mixed deciduous forests are recorded in the surroundings of the settlement. Plant macroremains reflect the characteristic Neolithic range of cultivated plants (e.g. Triticum monococcum, Triticum dicoccon, Lens culinaris and Pisum sativum). Papaver somniferum seeds were also found, possibly constituting the oldest evidence of its presence and cultivation in the territory of the Czech Republic.     

Settlement and Subsistence in the Remote Western Pacific: Archaeological and Radiocarbon Data from Alamagan,Northern Mariana Islands

Small, remote islands were marginal environments for prehistoric human populations. We report archaeological and radiocarbon data from Alamagan, a small and isolated island in the northern part of the Mariana Islands archipelago. Challenging environmental conditions, including rugged terrain, active or recent volcanism, and uncertain freshwater availability posed significant challenges for permanent settlement throughout the Northern Islands. The Alamagan archaeological investigations documented 14 megalithic domestic structures, or latte sets, as well as isolated and non-portable Latte Period artifacts, and one historical site. Test excavations were undertaken at two of the latte features. These investigations add to a growing body of data suggesting colonization of the Northern Islands during the middle part of the Latte Period (probably during the late a.d. 1200s or early 1300s). We consider the implications of these data for the study of human adaptations to marginal insular environments in the Pacific.     

Evaluation of bone strontium as a measure of seafood consumption

The recognition that bone strontium/calcium ratios reflect dietary levels of strontium and that seawater has a high strontium content led some archaeologists to infer that seafood consumption produces high Sr/Ca ratios in bone. Analyses of seawater and of marine organisms reveal, however, a marine trophic effect comparable to the trophic effect seen in terrestrial food chains. This marine trophic effect reduces the Sr/Ca levels in seafood such that marine dietary resources have Sr/Ca levels comparable to those of terrestrial resources. Thus, bone Sr/Ca ratios can not differentiate consumption of marine and terrestrial resources. Also, Sr/Ca of bones from archaeological sites where seafood was an important component of diet were found to be within the range of entirely terrestrial diets.

Geographical Influences on Settlement-Location Choices by Initial Colonizers: a Case Study of the Fiji Islands

From 3200 to 2850 cal BP (1250–900 BCE), the Lapita people of the Bismarck Archipelago (Papua New Guinea) undertook voyages eastward that led to their colonization of the eastern outer Solomon Islands, Vanuatu, New Caledonia, Fiji, Tonga and Samoa. The earliest (Lapita) settlements in Fiji were along the Rove Peninsula in southwest Viti Levu Island. At the time of colonization, sea level was 1.5 m higher than today. The Rove Peninsula was then a smaller island off the coast of larger Viti Levu, with a broad, fringing reef along its windward coasts, which was probably the main attraction for Lapita colonizers. As elsewhere during Lapita times in the western tropical Pacific Islands, settlement choice for the initial colonizers of the Fiji Islands was at one level driven by site access, at another by the presence of broad, fringing coral reefs suitable for marine foraging. The earliest settlement along the Rove Peninsula was at Bourewa, occupied first in 3050 cal BP (1100 BCE), where people lived in houses on stilt platforms built along the axis of a subtidal sand barrier; on one side was a broad coral reef, on the other a partly-enclosed tidal inlet. There is no evidence that the Bourewa settlers practised horticulture or agriculture at this time, their subsistence being predominantly marine foraging. After some 300 years of following this subsistence strategy, the inhabitants of Bourewa responded to sea-level fall and the arrival of cultivars (of taro and yam) by including horticulture. As sea level fell further, a total of 550 mm during the Lapita era, the tidal inlet dried up and marine-food resources diminished to a point where the natural environment of the Rove Peninsula could no longer sustain its Lapita inhabitants. All Lapita sites in the area were abandoned about 2500 cal BP (550 BCE), at the same time as the Lapita culture, marked by the end of dentate-pottery manufacture, came to an end in Fiji.     

Activity-induced musculoskeletal stress markers (MSM) and subsistence strategy changes among ancient Hudson Bay Eskimos

Although archaeological evidence may express the results of several seasons of activity, the human skeleton, when correlated with archaeological and ethnographic data, provides information concerning daily activities performed throughout an individual's lifetime. Studies in occupational and sports medicine, along with electromyographic analysis of movement, have shown that different activities place different amounts of stress on human bone. In the present study, analysis of upper extremity musculoskeletal stress markers (MSM) has been used to clarify habitual activity patterns of two ancient Thule Eskimo groups from northwest Hudson Bay, Canada. Distinct pattern differences in muscle use occurred between Thule adult males and females and suggest possible gender-specific activity patterns that are not always discernible from the archaeological record alone. Temporal applications of the MSM data for Early and Late Period Thule support McCartney's theory of a substantial change in subsistence strategies through time, particularly among the adult males.
