Stable carbon and nitrogen isotope variations in tooth dentine serial sections from Wharram Percy

Here we report δ¹³C and δ¹⁵N measurements of serial sections of human deciduous and permanent tooth dentine from archaeological samples taken from the medieval village site of Wharram Percy, Yorkshire, UK. We found a pattern of enrichment, for both δ¹³C and δ¹⁵N, where the tooth crown was greater than the cervical part of the root, which in turn was greater than the apical portion of the root and the associated rib collagen values. This pattern reflects a decrease in the consumption of isotopically enriched breast milk and the introduction of less enriched weaning foods in the diet. The (mean±SD) difference between the deciduous second molar crowns and corresponding rib samples from the same individuals after 2 years of age was 1.2±0.4‰ for δ¹³C and 3.2±0.8‰ for δ¹⁵N. The δ¹⁵N values are as predicted, but as there were no C₄plants at Wharram Percy, this 1.2‰ enrichment in δ¹³C represents clear evidence of a carbon trophic level effect in collagen from breastfeeding infants. Carbon and nitrogen results also show that the infant diet among those who died in infancy did not differ from those who survived into childhood. This study demonstrates the promise of using dentine serial sections to study the temporal relationships of breastfeeding, weaning, and dietary patterns of single individuals.     

Prey Choice During the South African Middle Stone Age: Avoiding Dangerous Prey or Maximising Returns?

Scrutinising prey choice allows the testing of hypotheses on whether the hunting capabilities of Middle Stone Age (MSA) people were as sophisticated as those of Later Stone Age hunter–gatherers. I apply an optimal foraging perspective to investigate whether MSA prey choice was constrained by the danger associated with hunting certain species. Here, I study the relative importance of elands, buffalo and suids. Eland was the most attractive prey to hunter–gatherers because it is large and docile. Buffalo and suids are more aggressive. When additional species to eland needed to be exploited, we would expect unsophisticated hunters to prefer the smaller suids over buffalo. If hunting prowess was sufficient to deal with both buffalo and suids, buffalo should be preferred. Due to their size, exploitation of buffalo would be more profitable than exploitation of suids. I show that, taking environmental circumstances into account, buffalo were preferred to suids, suggesting that MSA people were capable, sophisticated hunters.     

Archaeobotanical and GIS-based approaches to prehistoric agriculture in the upper Ying valley,Henan, China

Archaeobotanical survey has sampled a series of late Neolithic to early Bronze Age settlements in the upper Ying valley (part of the central plain of China) and provided useful data for understanding prehistoric arable ecology and farming during a period of increasing local social complexity. A combination of the modelling functions offered by Geographic Information Systems (GIS) and the data reduction possibilities offered by Principal Component Analysis (PCA) allow us to explore possible relationships between local arable ecology, crop-processing strategies and the natural environment. The results should be treated cautiously given the size of the analytical sample but suggest that differences in the natural environment around each site may explain varying patterns of wild food collection, while social and cultural factors may better explain variation in farming practice and crop-processing at different sites.     

Twenty-First-Century Historical Archaeology

The practice of historical archaeology has exploded over the past two decades, and especially since 2000. Methodological advances and new theoretical insights mean that archaeological research requires periodic evaluation, and this overview builds on the work of three earlier assessors of the discipline. Here, I concentrate on four areas of research currently being pursued by historical archaeologists: analytical scale, capitalism, social inequality, and heritage and memory. I conclude that historical archaeologists have made major strides in understanding the modern world and that future research promises to offer diverse perspectives that will deepen our appreciation for how the past influences the present.     

The Prehistoric Development of Clothing: Archaeological Implications of a Thermal Model

This paper presents a thermal model for the prehistoric origin and development of clothing. A distinction is drawn between simple and complex forms of clothing, with broad implications for the interpretation of paleolithic technological transitions and the emergence of modern human behavior. Physiological principles and paleoenvironmental data are harnessed to identify conditions requiring simple, loosely draped garments and the more challenging conditions that demanded additional protection in the form of complex garment assemblages. No actual clothing survives from the Pleistocene, yet the archaeological record yields evidence for technological and other correlates of clothing—more evidence than is generally supposed. Major innovations and trends in the distributions and relative frequencies of lithic and other tool forms may reflect the changing need for portable insulation in the context of fluctuating ice age climates. Moreover, the nonthermal repercussions of complex clothing can be connected with archaeological signatures of modern human behavior, notably adornment. Alternative models are less parsimonious in accounting for the geographical and temporal variability of prominent technological and other behavioral patterns in association with environmental change.
