Stable Isotope Analysis of Human and Animal Remains at the Qijiaping Site in Middle Gansu,China

Intercontinental exchanges between communities living in different parts of Eurasia during the late prehistoric period have become increasingly popular as a topic of archaeological research. The Qijia culture, found in northwest China, is one of the key archaeological cultures that can shed light on trans‐Eurasian exchange because a variety of imports are found in this cultural context. These imports include new cereals and animals, which suggest that human diets may also have changed compared with previous periods. To understand human and animal diets of the Qijia culture, carbon and nitrogen isotope ratios from human and animal skeletal remains were analysed from the type site of the Qijia culture at Qijiaping. The results demonstrate that human diet at the site mainly consisted of millet and animals fed on millet. C₃ cereals, such as wheat and barley, did not contribute significantly to human diet, and no isotopic differences were found between adult and subadult diets. Furthermore, three outlying human results raise the possibility of exogenous individuals, perhaps in relation to the parallel movement of animals, crops and goods. This study provides human and animal dietary information for evaluating the nature of exchange and diffusion in eastern Eurasia at this time. Copyright © 2013 John Wiley & Sons, Ltd.     

Diverse lifestyles and populations in the Xiaohe culture of the Lop Nur region,Xinjiang, China

The archaeological culture found in Xiaohe Cemetery (1980–1450 BC) is one of the early Bronze Age cultures in Xinjiang, northwestern China. The material assemblages from Xiaohe culture display features with both eastern and western influences. These east-west cultural and dietary interactions may be observed via the diet of the Xiaohe population. This paper examined the stable carbon and nitrogen isotopes of human and animal bones and human hairs from the Xiaohe Cemetery and compared with those of human bones from the Gumugou Cemetery, another Xiaohe culture site. The results indicate that the diets of the peoples from the Xiaohe culture varied significantly over different periods. The unified diets of the earlier periods reflect that an admixed population first settled in the Lop Nur region and primarily engaged in animal husbandry. In the later periods, the transformations in the human diets in this region reflect that new immigrants constantly relocated here and promoted population complexity over time. Moreover, this population occasionally produced small quantities of domesticated wheat and millet. The complex population and diversified economy of the Xiaohe culture were due to the expansion of the coeval cultures in the Eurasian steppe and eastern immigrants. Additionally, the millet cereal was probably mainly used for ritual practices rather than for staple food in the later periods.     

Dietary change in Fijian prehistory: isotopic analyses of human and animal skeletal material

We examine evidence for prehistoric diet in the Fiji Islands through the analysis of stable isotope ratios (δ¹³C and δ¹⁵N) for 26 samples of human and animal bones from various archaeological sites, time periods, and local environments. The oldest individuals in this study, dating to about 2700 BP and living on the small island of Waya, consumed a predominantly marine-based diet. Subsequent populations on this island showed reduced consumption of marine resources, with greater reliance on terrestrial ones, throughout the cultural sequence. In contrast, populations of humans and pigs living inland on Viti Levu, the largest island, relied on terrestrial resources since at least 1500 BP. Thus, our results suggest that human and pig diets throughout Fijian prehistory relied variably on marine or terrestrial resources, and this distinction is largely a product of geography. This finding and our analyses provide a model for understanding ancient diets in Remote Oceania.     

Stable isotope investigations of charred barley (Hordeum vulgare) and wheat (Triticum spelta) grains from Danebury Hillfort: implications for palaeodietary reconstructions

Palaeodietary studies typically focus on the analysis of bone collagen due to the limited availability of plant remains. Isotopic analysis of plant remains, however, allow for a more extensive consideration of the contribution of plants to the human diet and can potentially provide information about the environment in which the crops were grown. This paper reports the results of carbon and nitrogen isotope analyses performed on charred barley and wheat grains recovered from pits within Danebury Iron Age hillfort. To the best of our knowledge, this is the first Iron Age site in Britain from which charred grains have been isotopically analysed. Our results suggest that cereals found at the hillfort were grown in several different environmental contexts. The isotope data demonstrate that the herbivores were not consuming a diet primarily based on grains as the δ¹⁵N values of the grains are very similar to those of the herbivores. Palaeodietary investigations typically assume that humans eating plant protein only would have the same δ¹⁵N value as the local herbivores. This assumption is clearly invalid at Danebury, where the humans and animals appear to have consumed either different parts of the same plants or different plants. Researchers typically interpret high differences between human and animal δ¹⁵N values as indicative of diets high in animal protein, however where major plant resources have δ¹⁵N values similar to those of the herbivores our ability to distinguish between plant and animal sources of protein in the diet is limited. Our research has demonstrated that whenever possible it is desirable to measure the isotopic signatures of potential major plant resources in order to understand past subsistence strategies.     

Early Neolithic diets at Baijia,Wei River valley,China: stable carbon and nitrogen isotope analysis of human and faunal remains

Stable carbon and nitrogen isotope values are presented for faunal and human bone collagen from Baijia, in the Wei River valley region of Shaanxi Province, China. The remains have a calibrated age range of ca. 5709–5389 BC, and correspond with the early Neolithic Laoguantai Period. Stable isotopic results indicate that human diets included millet and probably aquatic foods such as fish and shellfish. Bovid samples are tentatively identified as water buffalo, and have a mean δ¹³C value of −14.6‰, which reflects some millet consumption. Whether bovids were grazing on wild millet, or had diets directly influenced by humans, is not known. The single Sus sample from Baijia had a diet dominated by C3 plants and is thus unlikely to have been a domesticated animal. Overall, the stable isotope results presented here conform to the current concept that the people of the Laoguantai culture were millet farmers, who had subsistence strategies that included hunted wild foods.     

Stable isotope analysis of humans from Xiaojingshan site: implications for understanding the origin of millet agriculture in China

Millet agriculture originated in Northern China in the early Neolithic period (ca. 8000 BP), however, the actual importance of millet in human diets is still not clear. To determine the relative contribution of millet in human diets in this period we undertook stable isotope analysis of humans from Xiaojingshan site and fauna from Yuezhuang site, both of which are attributed to the Houli Culture and date to about 8000 years ago. The carbon isotope values of human bone collagen showed that millet (as a C₄ plant) only contributed approximately 25% of dietary protein, with the rest from C₃ based plant and animal sources, if a simple mixing model is used. We did not observe any statistical dietary difference between males and females at the site, although it has been argued that the Houli Culture was a matriarchal society. Finally, we compared our data with other published isotopic data from the contemporary Jiahu site and Xinglongwa site and a number of sites from the subsequent Yangshao Culture and found that millet only became a significant source of dietary protein approximately 1000 years later, as human carbon isotope values from these later sites indicated that almost all of dietary protein came from C₄ (i.e. millet) sources.

Jasbir K. Puar,Terrorist Assemblages: Homonationalism in Queer Times

The importance of studying human–animal relationships and animal subjectivity is increasingly recognised by social and cultural geographers, particularly in agricultural pursuits. Little research, however, has been undertaken on animals in sport, resulting in a limited understanding of the perceptions and treatment of animals in society. To address this concern, we interrogate print media coverage of the construction and positioning of horses and humans in the controversial activity of jumps racing (National Hunt) in Australia between February 2008 and December 2009. We highlight the importance of seemingly contradictory human–animal relationships involving close frequent contact of some jumps racing advocates in contrast to the distanced, mediated relationships of jumps racing opponents. This paper highlights how the particular activity of jumps racing generates specific human–animal relationships and emphasises the need to reflect on the attitudes that shape and constrain human–animal relationships in varying contexts, including how these attitudes are mediated and the potential consequences for humans and other animals. These findings form the basis for a suggested research agenda that recognises the importance and articulation of proximity and mediation in human–animal relationships, particularly those focused on activities labelled ‘sport’.     

Integrating isotopes and documentary evidence: dietary patterns in a late medieval and early modern mining community,Sweden

This study explores the relationship between dietary patterns and social structure in a pre-industrial mining community in Salberget, Sweden c. 1470 to 1600 A.D. using a combination of different research approaches and tools, including archaeology, osteology, bone chemistry and history. The correlation between demographic criteria (sex and age) and archaeological variables (burial type and burial location) shows that Salberget was a highly stratified community. Group diets were investigated through analyses of stable isotopes (carbon, δ ¹³C, and nitrogen, δ ¹⁵N) of bone collagen from a sub-sample of individuals buried at the site (n = 67), interpreted alongside data from human dental lesions and deficiencies, animal bone waste and information on eating habits extracted from the extensive historical documents regarding mining activities at Salberget. These integrated analyses provide a clear association between social status and diet and confirm that social status, and to a lesser extent sex, gender and age, likely governed food choice and opportunity in this diverse community.     

Ritual Patterns in the Deposits of Fauna Associated with Iberian Burials: The Necropolis of El Poblado During the Fourth to Second Centuries bc (Archaeological Complex of Coimbra del Barranco Ancho,Murcia)

The study of grave goods, including animal deposits, offers a deeper understanding of social issues. This paper presents the results of the analysis of human and animal bone samples from the Iberian necropolis of El Poblado, Murcia. The examination focusses on 18 deposits of ovicaprids radii and ulnae, mostly of the left side, that were derived from 14 cremation tombs of the 74 studied. By considering the human and animal remains together, it is possible to highlight differences in the rituals of certain graves and variations in animal symbolism related to human sex and age. This provides a new understanding of the social and cultural differentiation that existed in the Iberian communities of this period. Copyright © 2012 John Wiley & Sons, Ltd.     

The impact of manuring on nitrogen isotope ratios in cereals: archaeological implications for reconstruction of diet and crop management practices

Recent archaeological studies of human diet have used stable nitrogen isotope ratios (δ¹⁵N) from human bone collagen to infer the relative importance of terrestrial plant and animal foods. This approach is based on widely observed enrichment of δ¹⁵N up the food chain, plants having distinctly lower values than the herbivores that consume them. Studies of early farming diets in Britain, Denmark and Germany have tended to detect relatively high δ¹⁵N values (e.g. c. +9‰), interpreted as evidence of a diet largely based on animal products, though archaeobotanical evidence for crop cultivation (e.g. carbonised cereal grain and chaff) is widespread. This paper investigates the impact of manuring on δ¹⁵N values in modern cereals, and of charring on these cereal values. The results from two long-term experiments demonstrate that manuring significantly raises δ¹⁵N in cereal grain and chaff. Depending on manuring levels and frequency, it appears that human diets with a major component of such grain would conventionally be interpreted as indicating a largely animal-based diet or a mixed plant/animal diet. Moreover, preliminary analyses of experimentally charred grain and chaff from manured and unmanured conditions are promising for the extraction of reliable ancient δ¹⁵N values from archaeobotanical cereal remains. The wider implications of these results, and the need for further work, are discussed.     

AN INVESTIGATION INTO DIET AT THE SITE OF YARNTON, OXFORDSHIRE, USING STABLE CARBON AND NITROGEN ISOTOPES

This paper reports the results of stable isotopic analyses conducted upon animal and human bones recovered from Yarnton, Oxfordshire. Spanning the Neolithic to Saxon periods, it is in many ways a typical site, but is unusual in that a small Middle Iron Age cemetery was discovered.
All of the data presented here lie within the expected isotopic ranges for the European Holocene, although both faunal and animal δ¹⁵N values are higher than is commonly found. The faunal data show the expected pattern for the animals studied (horse, cattle, sheep/goat, pig and dog), with pigs being more omnivorous than ruminants, and dogs eating an isotopically similar diet to humans. The animals' diets had higher δ¹⁵N values during the Roman period as compared to the Iron Age, although it is unclear if this reflects an environmental change or alteration in animal management practices. Despite the site's riverine location, there is no isotopic evidence for fish consumption. No distinctions were found based on gender or burial position within the Iron Age cemetery. Age-based distinctions were found in δ¹³C values, although these cannot be fully explained. As expected, infants have a higher nitrogen isotopic value than other individuals, reflecting the consumption of their mother's milk.     

Beyond the grave: variability in Neolithic diets in Southern Germany?

Carbon and nitrogen stable isotope analyses were undertaken on human and faunal remains from two Neolithic sites in Southern Germany; the LBK settlement at Herxheim and the middle Neolithic cemetery at Trebur. Stable isotope data were used to reconstruct the diets of individuals buried at these sites and to look at dietary variation between groups classified by their sex, age, grave goods and cultural affiliation. Overall there was surprisingly little variation in the diet between the groups, as described by the stable isotope analysis, despite significant differences in the composition of grave goods. Also surprising, considering the archaeological evidence for extensive grain cultivation in this region during the Neolithic, was that the majority of individuals had δ¹⁵N values consistent with the consumption of significant amounts of animal protein.     

Ancient molecules and human prehistory

Abstract

DNA and other molecules found in ancient remains are yielding new information about the origins, spread, interaction, and culture of early humans. Molecules of animal fats preserved in archaeological pottery have shown that in medieval societies people ate non-ruminant animals, such as pigs, but burned tallow from ruminants, such as sheep and cattle. Geochemical analysis of bitumen in the Middle East has documented ancient trade routes. Studies of molecular genetic diversity have shed light on when and how cattle were domesticated. Analysis of human hair from remains up to 5200 years old has revealed the diets of those ancient people. DNA recovered from other remains has also provided evidence for theories about the origins and spread of agriculture, and human migration into the Pacific.     

‘Of place’ or ‘of people’: exploring the animal spaces and beastly places of feral cats in southern Ontario

Feral cats are contentious and transgressive, with opposing views on whether to classify them as abandoned pets, wild animals, or invasive species. Concerns about their welfare often conflict with fears that they are impacting native fauna. This paper presents the results of a case study of human–feral cat relations that took place in southern Ontario, Canada in 2014. This research investigates the discursive constructions of feral cats and their ‘animal spaces’ using the results of 40 semi-structured interviews. Following recent calls to move beyond human representations of animals and better integrate animals’ geographies, this study also explores the ‘beastly places’ of feral cats using the results of field observations of 20 feral cat colonies and anecdotal evidence from colony caretakers. The results emphasize the diversity of free-living contexts and the complexity of management options. This paper ends by discussing the place-making practices of cats, along with their potential ethical ramifications. Overall, it illustrates the importance of spatial factors in understanding the complex social and ethical dynamics of human–animal relations, and advances an understanding of nonhuman animals as inhabitants of personally meaningful homes.

Neolithic Hedgehogs (Erinaceus europaeus) from the Island of Gotland show early contacts with the Swedish mainland

Previous research probing early migrations and contacts in the Baltic Sea area is characterized by the analysis of different chronologies and subsistent strategies on all sides of the Sea. Several studies performed on artifact typology, ceramics, grave rituals and physical anthropology ended with varying results. Although the question of human origins remains inconclusive, in this study, we rely on the phylogeography of an animal associated with humans to elucidate findings regarding prehistoric human migration and contacts.Hedgehogs, along with other fauna on Gotland, were brought over to the island by humans. We examined hedgehog mitochondrial DNA from the Pitted Ware Culture (Middle Neolithic). The genetic signatures of the animals on the island were investigated to determine the animal’s origin.From the 23 bones originally examined, twelve bones from all five locations studied yielded reliable results and resembled published extant Erinaceus europaeus sequences from Sweden, Norway and Denmark. We postulate that a western heritage for the Neolithic hedgehogs on Gotland indicates early human contact with the Swedish mainland.     

Palaeodiet at Eton College Rowing Course, Buckinghamshire: isotopic changes in human diet in the Neolithic, Bronze Age, Iron Age and Roman periods throughout the British Isles

Through isotopic investigations of directly dated human remains recovered from the Eton College Rowing Course, we examine changes in diet from the Neolithic to the Roman period. The human isotope signatures point to a diet based on C₃ terrestrial resources. A significant correlation is visible between human ??¹³C values and time, but no such trend is observed in ??¹⁵N. The animal isotope data from Eton are unevenly distributed, making it difficult to determine if the human values mirror the animal values. To assess whether the results from Eton are typical, we compare our results to isotope data from other British sites dating from the Neolithic to the Roman period. Across this time period, we see a strong correlation between the mean ??¹⁵N of the humans and that of the main domesticated herbivores, with an offset of ??4.5?? between the two. Thus, the changes in the human isotope values are likely linked to changes in the isotopic signatures of the herbivores rather than changes in the protein composition of human diets. By contrast, no clear temporal relationship is observed between the mean ??¹³C of the humans and that of the main domesticated herbivores, with an offset of ??1.4?? between the two. There is, however, a weak correlation observed between the mean ??¹³C of the humans and that of the cattle, which may account for some of the variation in human ??¹³C values between sites. The absence of a strong correlation between mean human and animal ??¹³C suggests that the primary factor influencing human ??¹³C values between sites is dietary composition. The lack of co-variation between ??¹³C and ??¹⁵N is likely to reflect the different representation of dietary macronutrients. Given that the nitrogen results suggest that the animal protein consumption patterns are similar across sites, the human ??¹³C variation between sites is likely to reflect the plant portion of the diet.

Reconstructing ancient Maya animal trade through strontium isotope (87Sr/86Sr) analysis

This study explores the potential for using strontium isotope analysis (⁸⁷Sr/⁸⁶Sr) to study ancient Maya animal exchange. Traditional zooarchaeological methods of studying trade rely on the identification of animals found outside their natural geographic or habitat ranges. Isotopic analysis provides an additional means of identifying and sourcing non-local animals. ⁸⁷Sr/⁸⁶Sr values from Maya zooarchaeological remains indicate that regional and long-distance transport and exchange of animal goods was more common than previously recognized. Widely distributed animals including deer and peccary were among the animals exchanged, which questions their common interpretation as locally-acquired resources. The isotopic results contribute to our understanding of how animal products were integrated into Maya economic and exchange networks. The research is also relevant to human mobility studies in Mesoamerica.
