Strontium isotope evidence of migration and diet in relation to ritual tooth ablation: a case study from the Inariyama Jomon site,Japan

Ritual tooth ablation was extensively practiced among Jomon (Japanese Neolithic) societies in their final phase (ca. 3000-2300 BP). This tradition includes two different tooth ablation patterns, type 4I and type 2C, referring to extraction of the mandibular incisors and canines, respectively. However, the reason for this difference is unclear. Previous carbon and nitrogen stable isotope analysis of human remains from the Inariyama shell mound revealed that type 4I individuals were more dependent on terrestrial resources and type 2C individuals on marine resources. To test this hypothesis, we performed strontium (Sr) isotope (⁸⁷Sr/⁸⁶Sr) analyses on the same skeletal remains and on modern plants around the site. Because Sr isotope ratios of plants differ according to the local geology and seawater has a consistent Sr isotope ratio, the Sr isotope ratios of tooth enamel can reveal both migration and diet. Comparing Sr isotope ratios in plants and seawater with those of tooth enamel, we identified four possible immigrants. Type 4I locals had significantly higher Sr isotope ratios than type 2C locals. The ratios of the type 4I and type 2C locals were close to those of terrestrial plants and seawater, respectively, suggesting that type 4I locals had incorporated much Sr from terrestrial resources and type 2C locals from marine resources. These results support the hypothesis that ritual tooth ablation reflects dietary differences throughout an individual’s life, and they suggest possible occupational differentiation among the Jomon people.     

The origin of black pigmentation in a sample of Mexican prehispanic human bones

The study of black patches and spots in prehispanic bones of Tlatelolco and Tlapacoya is presented. The chosen characterization techniques, X-ray Fluorescence, X-ray Diffraction, Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy, Infrared Spectroscopy and Gas Chromatography are complementary and they all conclude that the bone black pigment is constituted, mainly, by amorphous carbon and some mineral inclusions. Gas Chromatography and Infrared Spectroscopy show that the pigment is constituted by organic compounds as aromatic hydrocarbons, mainly bitumen. An explanation on how the spots were formed is proposed.     

Ways In and Out of Vulnerability to Climate Change: Abandoning the Mubarak Project in the Northern Nile Delta,Egypt

Abstract: Climate change is already exerting significant pressure on humanity, but some people have the resources to cope, while others do not. What, then, determines vulnerability to climate change? This article presents a case study of one site of vulnerability in Egypt, known as the Mubarak Project villages on the shores of the Mediterranean. The soil of these villages is now undergoing rapid salinization, forcing farmers to apply sand to “elevate” their fields above the rising salty water table—but not all farmers can afford to buy the requisite sand. Accumulation by dispossession under the Mubarak regime has pushed some people towards the frontline of climate change, while at the same time denying them the resources to stay there. Using our case, we explore the connection between accumulation by dispossession and vulnerability to climate change and ask if an end to the former could reduce the latter in Egypt.     

Banking Nature? The Spectacular Financialisation of Environmental Conservation

Abstract: In this paper I emphasise the financialisation of environmental conservation as 1. the turning of financiers to conservation parameters as a new frontier for investment, and 2. the rewriting of conservation practice and nonhuman worlds in terms of banking and financial categories. I introduce financialisation as a broadly controlling impetus with relevance for environmental conservation. I then note ways in which a spectacular investment frontier in conservation is being opened. I highlight the draw of assertions of lucrative gains, combined with notions of geographical substitutability, in creating tradable indicators of environmental health and harm. I disaggregate financialisation strategies into four categories—nature finance, nature work, nature banking and nature derivatives—and assess their implications. The concluding section embraces Marx and Foucault as complementary thinkers in understanding the transforming intensifications of late capitalism in environmental conservation, and diagnosing their associated effects and costs.     

Cutmark systematics: Analyzing morphometrics and spatial patterning at Palangana

Cutmarks have played an important role in addressing whether our hominid ancestors were hunters or scavengers, describing ritual modification of human bone, defining the origin of metallurgy, and highlighting the diversity of prehistoric butchering behavior. The widespread occurrence of cutmarks on animal bones and their variability allows archaeologists to use this kind of evidence to address a broad range of questions. One goal in examining cutmark diversity is to identify diagnostic cutmarks of prehistoric butchering, processing, and consuming behaviors. Linking cutmarks to specific activities allows us to test fine-grained hypotheses concerning the nature of an archaeological site, and to do this a systematic method for addressing variability in both the appearance and anatomical position of cutmarks is essential. An analysis of caribou bones collected by Lewis Binford from the Palangana site in Alaska is used to build and test a diagnostic cutmark classification using their morphometric and spatial properties. This case study demonstrates that cutmarks can be used to simultaneously address large-scale anthropological questions and reveal intra-site behavioral variability in the archaeological record.     

A cautionary note on the use of captive carnivores to model wild predator behavior: a comparison of bone modification patterns on long bones by captive and wild lions

A study with wild lions in Tarangire National Park (Tanzania) and with captive lions in Cabárceno Reserve (Spain) has yielded two different bone modification patterns, probably as a result of the differences in environmental contexts. Captive lions have modified bones more intensively, both in the form of total number of tooth-marked bones and number of tooth marks per tooth-marked bone, probably because of stereotypic behaviors. This emphasizes the importance of environmental contexts to understand carnivore behavior and their resulting bone modification patterns. It also shows that analogical models based on experiments carried out with captive carnivores may be biased and inadequate as proxies for wild carnivore bone modification behaviors.     

Reconstructing Life Histories Using Multi‐Tissue Isotope Analysis of Commingled Remains from St Stephen's Monastery in Jerusalem: Limitations and Potential

The examination of isotope ratios from multiple tissues offers new life to interpretations of commingled assemblages where information regarding individual biological history has been lost. Here, life histories from a commingled sample of Byzantine monks were reconstructed using enamel and bone δ¹³C and δ¹⁵N values. The δ¹³C values suggest a diet dominated by C₃ products, while the δ¹⁵N ratios indicate variable contributions of animal protein. After correcting for tissue‐specific enrichment factors, bone δ¹³C values were significantly enriched over enamel; this may be due to an increase in protein consumption, but could also reflect structural differences between tissues or correction factors used to compare these data.     

Cross-cultural interaction on Wuvulu Island,Papua New Guinea: the perspective from use-wear and residue analyses of turtle bone artifacts

Recent studies have emphasized the importance of Indigenous producers and traders in the formation of ethnographic museum collections, but have found difficulty in finding concrete evidence for their active roles. A use-wear and residue study of turtle bone cleavers from Wuvulu Island, Papua New Guinea provides the opportunity to test whether objects that comprise a significant component of early collections were made specifically for sale, as hypothesized by contemporary observers in the late 19th century. Comparative studies of used and unused turtle bone artifacts from the Caroline Islands and Papua New Guinea identified differences between wear traces resulting from manufacture and use. Analyses of the Wuvulu turtle bone cleavers showed they had been heavily used prior to sale. Rather than produce artifacts to meet the high demand from German traders, the local people sold old, worn-out objects, many of which had been repaired. The study demonstrates that archaeological approaches to ethnographic museum collections can trace Indigenous agency within cross-cultural interaction. It also showcases the potential of use-wear and residue analytical techniques for the analysis of bone tools and the utility of digital, hand-held microscopes for the analysis of large artifacts.     

Stable isotopic analysis of human bones from Jiahu site,Henan, China: implications for the transition to agriculture

We have investigated change in subsistence during the transition to agriculture in the site of Jiahu, Henan Province, China, using stable isotopic analysis of collagen and apatite in human bones. Millet agriculture is well documented at drier high latitudes of the Yellow River Valley, while rice agriculture predominated at wetter lower latitudes of the Yangtze Valley region. The early Neolithic site of Jiahu lies near the boundary between the drier north and wetter south. Archaeobotanical evidence shows that rice was a significant component of diet at Jiahu, but its δ¹³C value is similar to that of other foods, and therefore cannot be conclusively identified by carbon isotope analysis. Foxtail and broomcorn millets are the only C₄ crops known for the Chinese Neolithic. Because of their high δ¹³C values, their consumption can be evaluated by stable carbon isotope analysis of human bone. Collagen reflects mainly the δ¹³C value of dietary protein, and apatite accurately records that of the whole diet. Isotopic analysis of 15 well-preserved samples from three periods shows that collagen δ¹³C values were very low for almost all individuals, suggesting C₃-based foods dominated their diets. However, apatite carbonate δ¹³C values and δ¹³C spacing between collagen and apatite (Δ¹³C_ap-co) indicate that millet may have been a minor component of the diet in this region. Individuals, who consumed the smallest amounts of animal protein, as indicated by low δ¹⁵N, generally had the highest apatite δ¹³C values. Archaeobotanical evidence for millet at Jiahu is needed to support this interpretation.
