Paleodiet of domestic turkey,Shields Pueblo (5MT3807), Colorado: isotopic analysis and its implications for care of a household domesticate

Isotopic analysis of domestic turkey (Meleagris gallopavo) bones from Shields Pueblo, southwest Colorado, USA, suggests that these birds consumed a diet high in C4 plants. This contrasts with the diet of local herbivores, where much lower percentages of C4 plants were recorded. In view of the prevalence of maize (Zea mays) in the human diet of Ancestral Puebloan people, we suggest that turkeys were fed food scraps and surplus maize, rather than being allowed to forage for themselves. This suggests that turkeys were carefully tended in the household. Analysis of specimens from other sites in the northern Southwest shows that this pattern of turkey feeding characterizes all of the sampled horticultural communities.     

The relationship of the Mimbres to other southwestern and Mexican populations

Previous aDNA research in the Southwest provides a framework to understand the Mimbres population which maintains a unique identity in the archeology of the desert Southwest of North America. Both the mitochondrial DNA (mtDNA) haplogroups and haplotypes of a sample of 46 Mimbres individuals were identified from skeletal remains and compared to those of other ancient and modern populations in the American Southwest and Mexico. The haplogroup frequency distribution of the Mimbres resembles that of other Southwestern populations, suggesting a close relationship between the Mimbres and the neighboring populations and population continuity for a long period of time. However, their relatively low frequency of haplogroup A (11% n = 5) is consistent with a clinal distribution of haplogroup A from Mesoamerica to the Southwest. Moreover, unlike other Southwestern populations, the Mimbres share haplotypes with populations to the south, such as the Cora, Huichol, and Nahua, suggesting gene-flow from Mesoamerica. Here we discuss this data in light of the origin of the Mimbres population and their relationship to other Southwestern and Mexican populations.     

Recent research in west Mexican archaeology

The last decade has seen the greatest increase in archaeological research in western Mexico since the 1940s. Unlike previously heralded renewals, this one is accompanied by widespread skepticism of the dominant culture-historical paradigm linking west Mexico to the rest of Mesoamerica, to the American Southwest, and to South America. Current research offers substantive new data and interpretations bearing on issues such as the definition of Mesoamerica, the role of South American long distance contacts, the human ecology of highland lakes, the role of river systems in Mesoamerican prehistory, and the nature/role of prehispanic elite exchanges.     

Reduced Population Variance in Strontium Isotope Ratios Informs Domesticated Turkey Use at Chaco Canyon,New Mexico,USA

Traditionally, strontium isotopes (⁸⁷Sr/⁸⁶Sr) have been used as a sourcing tool in numerous archaeological artifact classes. The research presented here demonstrates that ⁸⁷Sr/⁸⁶Sr_bioapatite ratios also can be used at a population level to investigate the presence of domesticated animals and methods of management. The proposed methodology combines ecology, isotope geochemistry, and behavioral ecology to assess the presence and nature of turkey (Meleagris gallopavo) domestication. This case study utilizes ⁸⁷Sr/⁸⁶Sr_bioapatite ratios from teeth and bones of archaeological turkey, deer (Odocoileus sp.), lagomorph (Lepus sp. and Sylvilagus sp.), and prairie dog (Cynomys sp.) from Chaco Canyon, NM, USA (ca. A.D. 800–1250). Wild deer and turkey from the southwestern USA have much larger home ranges and dispersal behaviors (measured in kilometers) when compared to lagomorphs and prairie dogs (measured in meters). Hunted deer and wild turkey from archaeological contexts at Chaco Canyon are expected to have a higher variance in their ⁸⁷Sr/⁸⁶Sr_bioapatite ratios, when compared to small range taxa (lagomorphs and prairie dogs). Contrary to this expectation, ⁸⁷Sr/⁸⁶Sr_bioapatite values of turkey bones from Chacoan assemblages have a much lower variance than deer and are similar to that of smaller mammals. The sampled turkey values show variability most similar to lagomorphs and prairie dogs, suggesting the turkeys from Chaco Canyon were consuming a uniform diet and/or were constrained within a limited home range, indicating at least proto-domestication. The population approach has wide applicability for evaluating the presence and nature of domestication when combined with paleoecology and behavioral ecology in a variety of animals and environments.     

Ancient DNA confirms a local origin of domesticated chenopod in eastern North America

Domesticated chenopod was an important starchy seed crop in eastern North America before the rise of maize agriculture. Domesticated chenopod first appeared in North America during the fourth millennium B.P., however its wild progenitor and site of domestication remain unresolved. Archaeological evidence suggests a local domestication in the Eastern Woodlands, while morphological similarities with modern Mexican cultivars indicate a possible introduction from Mesoamerica. To distinguish between these two scenarios, we isolate chloroplast DNA (cpDNA) from modern and archaeological North American chenopods sampled from across their geographic range. Our results demonstrate that the chenopod grown in the Eastern Woodlands was locally-derived, indicating that independent domestication events gave rise to the ancient eastern North American and modern Mexican cultivars. These results strengthen the argument for an entirely native pre-maize crop complex with chenopod as a major component.     

The evolution of rice: molecular vignettes on its origins and spread

The domesticated species Oryza sativa or Asian rice evolved starting approximately 9,000 years ago and from its centers of origin in China and India has subsequently spread throughout the Old World (and in historical times in the New World as well). This species is one of the key domesticated crop plants in the world and has emerged as a model for studying the origins and spread of domesticated taxa as well as in investigating the genetic basis for plant variation under domestication. Archaeological data has been critical in dissecting the origins and spread of rice throughout Asia, but molecular information has also provided a complementary approach to examining the evolutionary dynamics of this species. The evolutionary history of a species can leave its footprints within its genome. Moreover, genetic studies allow us to study the history of traits that do not leave an archaeological record—for example, grain stickiness or flowering time—which can provide insights into how crop species are adopted by different cultures. In this review, several molecular studies into the origin and spread of Asian rice are discussed and we explore the advances these genetic studies offer in our understanding of the evolution of domesticated species. We also explore how archaeological data can provide critical insights that can help refine genetic models of the origin and spread of domesticated species.     

关于中国稻作起源证据的讨论与商榷

本文是对傅稻镰等人最近的文章批评中国栽培水稻起源研究缺乏证据、提出长江下游水稻栽培开始于公元前4000年这一观点一文的回应。我们首先考察中国从野生稻采集到水稻栽培过程研究的相关文献．进而从水稻形态学和考古学的角度对早期水稻遗存加以研究。讨论集中在以下三个方面：长江流域最早水稻栽培的时间：长江下游和淮河流域初期栽培水稻的遗存;考古遗存所见水稻粒形态大小变化的意义。我们也考察了傅文用来区分野生水稻和栽培水稻的几个标准：考古纪录中所见的未成熟稻遗存、水稻粒的增大和水稻粒的形态。根据已经发表的资料和我们对水稻的研究,我们认为到全新世早期（距今9000年前后）,南北中国的新石器时代居民就可能已经收获野生稻并开始水稻栽培了。     

Plant exploitation of the last foragers at Shizitan in the Middle Yellow River Valley China: evidence from grinding stones

China is one of the few centers in the world where plant domestication evolved independently, but its developmental trajectory is poorly understood. This is because there is considerably less data from the terminal Pleistocene and early Holocene documented in China than in other regions, such as the Near East and Mesoamerica, and previous studies on Paleolithic subsistence in China have largely focused on animal hunting rather than plant gathering. To resolve these problems the current research investigated the range of plants used by late Paleolithic hunter–gatherers in the middle Yellow River region where some of the earliest farmers emerged. We employed usewear and starch analyses on grinding stones to recover evidence for plant use in a hunting–gathering population at a late Paleolithic site, Shizitan Locality 9 in Jixian, Shanxi (ca. 13,800–8500 cal. BP). The usewear analysis shows that all artifacts preserved a range of usewear patterns best matching multiple tasks and indicating multi-functional use. Starch remains recovered from these tools indicate that the Shizitan people collected and processed many types of grass seeds (Panicoideae and Pooideae subfamilies), acorns (Quercus sp.), beans (Phaseoleae tribe) and yams (Dioscorea sp.). The Shizitan people represented some of the last hunter–gatherers in the middle Yellow River region. Their broad spectrum subsistence strategy was apparently carried on by the first Neolithic farmers in the same region, who collected similar wild plants and eventually domesticated millets. The trajectory from intensified collection of a wide range of wild plants to domestication of a small number of species was a very long process in north China. This parallels the transition from the “broad spectrum revolution” to agriculture in the Near East.

Eggshell and the archaeological record: new insights into turkey husbandry in the American Southwest

Eggshell in the archaeological record has interpretive potential beyond simple species identification. Structural features of eggshell itself indicate the degree of development of the embryo. Using a scanning electron microscope, a reference collection of modern eggshell characteristics has been produced that can be used for species determination and for the assessment of embryo development of prehistoric eggshell. We apply this technique to a sample of prehistoric eggshell from northwestern New Mexico and conclude that purposeful breeding of captive turkey populations is present during the 12th century AD. These preliminary results suggest a behavioral shift in turkey husbandry, concomitant with the well documented phenomenon of intensified turkey utilization after about AD 1100 in the American Southwest.     

The prehistoric drug trade: widespread consumption of cacao in Ancestral Pueblo and Hohokam communities in the American Southwest

We propose the existence of extensive trade and interaction among the peoples of the American Southwest and Mesoamerica. We base this inference on our detection of the widespread presence of theobromine, the biomarker for cacao, in 50 of 75 vessels used by Ancestral Puebloans (previously referred to as Anasazi) elites and non-elites from the Four Corners area and Hohokam elites of the Gila and Salt river valleys in the prehistoric American Southwest. We used a non-invasive, non-destructive aqueous sampling procedure that provides conservation advantages over the current methods that require crushing and boiling sherds or removing residues from vessel surfaces. Analysis of these samples by sensitive LC-MS instrumentation capable of detecting nanogram quantities of material revealed theobromine in non-local vessel forms found in elite burials in great house and platform mound sites as well as in local vessel forms used by non-elites living in small unit-pueblos. After elimination of plants native to the Southwest as the source of theobromine, we conclude that either Theobroma cacao or Theobroma Bicolor was imported from its homeland in the Mesoamerican tropical coastal lowlands. Our results are at odds with the current consensus that there was little systematic commerce between Mesoamerican and Southwestern polities. We suggest that cacao was exchanged for high quality turquoise such as that mined in the Cerrillos, New Mexico mining district. We conclude that, far from being isolated developmentally, this trade integrally tied populations in the American Southwest to the socio-political and economic activities of Mesoamerican states.     

Ancient olive DNA in pits: preservation,amplification and sequence analysis

The olive tree (Olea europaea) was domesticated by vegetative propagation of selected wild individuals with superior fruit. Later, new cultivars were established repeatedly from feral trees or from crosses between wild, feral, and domesticated trees. Thus the genetic background of many contemporary domesticated lines is a mixture of ancient cultivars and local wild trees. Ancient DNA may illuminate the complicated process of olive domestication because such DNA sequences provide data about ancient genomes that existed closer to the domestication events. Well preserved DNA must be available for such studies, even though in the Mediterranean region, where olive cultivation took place, the climatic conditions are not favorable for DNA preservation. To select for well preserved pits we measured their proportions of lignin by IR spectroscopy, and correlated this with parameters of DNA quality such as template length in an olive-specific repeat array, and template quantity as determined by real-time PCR amplification. Archaeological pits that passed these tests did contain high quality ancient DNA. We present the first ancient olive DNA sequences and compare them to modern wild, feral and domesticated lines.     

First Approach to Study the Presence of Domesticated Camelids (Lama glama) in the Chaco‐Santiago Region,a Marginal Zone of the South Central Andes

We analysed bone remains of camelids from the Maquijata site, assigned to the late pottery‐making and farming stage (ca. 800–400 BP), in order to differentiate between domestic and wild species in the Chaco‐Santiago archaeological region. This region is considered marginal to the Argentine Northwest regarding its cultural development and has received less attention than other regions. South American camelids have been one of the major resources in this continent, with domestication recorded in the South Central Andes at around 4400–3000 BP. We applied osteometric techniques and multivariate statistical analyses to proximal phalanges; the results showed interspecific differentiation of archaeological specimens, though with some methodological application issues. These results are the first contribution regarding the presence of domesticated animals in the study area. Copyright © 2012 John Wiley & Sons, Ltd.     

Faunal changes in farming communities from Basketmaker II to Pueblo III (A.D. 1–1300) in the San Juan Basin of the American Southwest

The San Juan Basin of the American Southwest is home to some of the best known architecture in pre-Columbian North America. Although many faunal assemblages have been reported for individual sites, there has been little synthesis of hunting and husbandry in these farming communities. In an attempt to understand changing animal usage over time in the San Juan Basin, we use three indices to investigate the usage of artiodactyls, lagomorphs and turkeys. These three taxonomic groups formed the bulk of meat diets between Basketmaker II and Pueblo III times (A.D. 1–1300). Our analysis indicates that artiodactyls declined over time in relation to lagomorphs. Turkeys increased in the northern regions when compared to lagomorphs. Cottontails increased when compared to jackrabbits over time. We suggest that as human populations increased in the San Juan Basin, artiodactyls were more intensely hunted. People then began to raise more turkeys in favorable regions, and also hunted more lagomorphs in relation to artiodactyls. Deforestation, also as a result of increased human populations, would have created conditions more favorable for cottontails than jackrabbits in many areas.     

Transition From Wild to Domesticated Pearl Millet (Pennisetum glaucum) Revealed in Ceramic Temper at Three Middle Holocene Sites in Northern Mali

Imprints of domesticated pearl millet (Pennisetum glaucum (L.) R. Br.) spikelets, observed as temper in ceramics dating to the third millennium BC, provide the earliest evidence for the cultivation and domestication process of this crop in northern Mali. Additional sherds from the same region dating to the fifth and fourth millennium BC were examined and found to have pearl millet chaff with wild morphologies. In addition to studying sherds by stereomicroscopy and subjecting surface casts to scanning electron microscopy (SEM), we also deployed X-ray microcomputed tomography (microCT) on eleven sherds. This significantly augmented the total dataset of archaeological pearl millet chaff remains from which to document the use of the wild pearl millet as ceramic temper and the evolution of its morphology over time. Grain sizes were also estimated from spikelets preserved in the ceramics. Altogether, we are now able to chart the evolution of domesticated pearl millet in western Africa using three characteristics: the evolution of nonshattering stalked involucres; the appearance of multiple spikelet involucres, usually paired spikelets; and the increase in grain size. By the fourth millennium BC, average grain breadth had increased by 28%, although spikelet features otherwise resemble the wild type. In the third millennium BC, the average width of seeds is 38% greater than that of wild seeds, while other qualitative features of domestication are indicated by the presence of paired spikelets and the appearance of nondehiscent, stalked involucres. Nonshattering spikelets had probably become fixed by around 2000 BC, while increases in average grain size continued into the second millennium BC. These data now provide a robust sequence for the morphological evolution of domesticated pearl millet, the first indigenous crop domesticated in western Africa.

     

Early North African Cattle Domestication and Its Ecological Setting: A Reassessment

Nearly four decades have passed since an independent North African centre for cattle domestication was first proposed in 1980, based on the Combined Prehistoric Expedition’s work in the Nabta Playa—Bir Kiseiba region of southern Egypt, and the initial rigorous debates between Andrew B. Smith and Fred Wendorf, Romuald Schild and Achilles Gautier. More recently, geneticists have entered the fray with determinations on the spread of haplotypes, and the timing thereof, that extend the scope and increase the complexity of the debate. Here, a new look at the botanical data and a re-analysis of the geology of Bir Kiseiba–Nabta Playa rejects the ecological foundations of the early African domestication model, while a detailed examination of the published osteological and radiometric data from the same area reveals a more nuanced picture than has been recognised to date. These results are placed into context by a wider review of the genetic and other archaeological evidence from the Western Desert of Northeast Africa, where no other cattle remains designated as domesticated have been found. It is concluded that (a) Bos remains from the early Holocene at Nabta Playa—Bir Kiseiba were those of hunted aurochs; (b) domesticated caprines were likely present in Northeast Africa before domesticated cattle; and (c) the domesticated cattle spreading across Northeast and northern Africa, including Nabta Playa—Bir Kiseiba, from the late seventh millennium BC or early sixth millennium BC onwards were descendants of Bos taurus domesticated in the Middle Euphrates area of the Middle East.     

The Archaeology of Food and Social Diversity

This article reviews current archaeological research on the interactions between food and intrasocietal diversity. Today’s archaeology of food and diversity is theoretically diverse but generally views food as biologically necessary and cognitively prominent material culture that plays an active role in constructing and negotiating social distinctions. Areal foci in the literature include Europe, Southwest Asia, Mesoamerica, the U.S. Southwest, and the Andes; thematic emphases include economic, status, ethnic, gender, and religious distinctions. Methodological issues that must be considered when assessing the social implications of food remains include not only the contexts and characters of specific samples but also the integration of multiple data sets that may all differ with respect to their taphonomic histories and the aspects of food behavior they reflect.     

The Secondary Products Revolution, Horse-Riding, and Mounted Warfare

Andrew Sherratt included horseback riding and chariotry in his conception of the Secondary Products Revolution, but his emphasis on the role of horses in warfare and on a Near Eastern influence in the earliest episode of horse domestication is viewed here as as an important shortcoming in his understanding of the process of horse domestication. Current evidence indicates that horses were domesticated in the steppes of Kazakhstan and Russia, certainly by 3500 BC and possibly by 4500 BC. Tribal raiding on horseback could be almost that old, but organized cavalry appeared only after 1000 BC. Riding might initially have been more important for increasing the productivity and efficiency of sheep and cattle pastoralism in the western Eurasian steppes. The earliest (so far) direct evidence for riding consists of pathologies on the teeth and jaw associated with bitting, found at Botai and Kozhai 1. Recent developments and debates in the study of bit-related pathologies are reviewed and the reliability of bit wear as a diagnostic indicator of riding and driving is defended.     

The Status Problem of Iberian Holocene Equids: New Data from Cueva de El Mirador (Sierra de Atapuerca,Spain)

Equid remains are scarce and very fragmented in Iberian Neolithic and Bronze Age sites. Evidence suggesting that horses were domesticated does exist, but it is often inconclusive, thus leaving the question unanswered. Today, DNA analyses have provided information about a, most likely Iberian, nucleus of horse domestication, making it crucially important to expand the database. The Holocene sequence (6^th and 3^rd millennium cal bc ) of the Cueva de El Mirador (Sierra de Atapuerca, Spain) has yielded 92 equid remains distributed in 12 Neolithic and Bronze Age levels. In this paper, we present the study of the equid remains from the Cueva de El Mirador from an archaeozoological perspective, giving indirect evidence of horse domestication. Our results vary widely and lead to open interpretations about horse domestication and how humans used these animals. This study of horse remains focuses on species identification and on determining how humans economically used these animals. Copyright © 2014 John Wiley & Sons, Ltd.     

Research Themes in the Cultural Geography of Domesticated Animals, 1974-1987

Ten themes have characterized recent studies of the cultural geography of domesticated animals. They are: origins of earliest animal domestication, domestication and dispersal of particular species, domesticated animals as agents in vegetation change, dairying and lactose intolerance, the cattle complex of Africa, the sacred cow of India, the pig complex of Melanesia, pastoralism, domesticated animals and human food, and domesticated animals and human disease.
