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.     

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。     

Mutualism on Australian heritage breed farms

For millennia, humans and domesticated animals have lived interdependently. In return for shelter, feed and care, animals have provided people with diverse material and symbolic resources within high-stakes mutualistic relationships. However, mutualisms are always susceptible to ‘cheaters’, where one partner enjoys the benefits without providing adequate reciprocation. When considering mutualisms on an ethnographic scale, industrial agriculture's reduction of animals to unidimensional commodities can be seen to constitute such cheating. By analyzing the practices of nourishment, procreation and protection on Australian heritage breed farms, where breed diversity and convivial interspecies reciprocity are valued above profit, this essay offers a case study of a more nuanced mutualism within the domestication nexus. Since partners in a mutualistic relationship tend to face a shared fate, protecting the integrity of these relationships is critical in an era where climate change and ecosystem decline are both hastened by and detrimental to agriculture.     

The Uncertain Origins of Mesoamerican Turkey Domestication

The turkey (Meleagris gallopavo) is the only domesticated vertebrate to originate from North America. Accurate reconstructions of the timing, location, and process of its domestication are thus critical for understanding the domestication process in the ancient Americas. A substantial amount of recent research has been devoted to understanding turkey domestication in the American Southwest, but comparatively little research has been conducted on the subject in Mesoamerica, despite the fact that all modern domestic turkeys descend from birds originally domesticated in Mexico during pre-colonial times. To address this disparity, we have conducted a review of the available literature on early turkeys in the archaeological record of Mesoamerica. We evaluate the evidence in terms of its accuracy and use this evaluation as a stepping off point for suggesting potential avenues of future research. Although the lack of available data from Mesoamerica currently precludes detailed cross-cultural comparisons, we briefly compare the origins and intensification of turkey rearing in Mesoamerica with the American Southwest to generate more dialogue among researchers independently studying the topic in these two distinct but interconnected cultural regions.     

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.     

Chickpea domestication in the Neolithic Levant through the nutritional perspective

An alternative approach to the process of selection and domestication of grain crops in early history based on nutritional value is proposed. Selection by a long trial and error process among a number of wild large seeded legumes gave rise to a nutritionally superior domesticated chickpea among the selected “founder crops” of the Neolithic Near Eastern agriculture. We found considerably higher free tryptophan levels in cultivated stocks (44 desi and 29 kabuli types from 25 countries; 1.10 mg/g seed dry weight), compared with the wild progenitor Cicer reticulatum (15 accessions; 0.33 mg/g seed dry weight). Dietary tryptophan determines brain serotonin synthesis, which in turn affects certain brain functions and human behaviour. We suggest that these nutritive facts may explain the decision of prehistoric farmers to choose this rare species and struggle to keep such an agronomically complicated crop under domestication.     

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.     

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.

     

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.     

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.     

Measured domestication rates in wild wheats and barley under primitive cultivation,and their archaeological implications

Man's (or, more probably, Woman's) first cereal crops were sown from seed gathered from wild stands, and it was in the course of cultivation that domestication occurred. Experiments in the measurement of domestication rates indicate that in wild-type crops of einkorn, emmer, and barley under primitive systems of husbandry: (a) domestication will occur only if they are harvested when partially or nearly ripe, using specific harvesting methods; (b) exposure to shifting cultivation may sometimes have been required; and (c) under these conditions, the crops could become completely domesticated within 200 years, and perhaps only 20–30 years, without any conscious selection. This paper (a) considers possible delays in the start of domestication due to early crops of wild-type cereals lacking domestic-types mutants; (b) examines the husbandry practices necessary for these mutants to enjoy any selective advantage; (c) considers the state of ripeness at harvest necessary for the crops to respond to these selective pressures; (d) outlines field measurements of the selective intensities arising from analogous husbandry practices applied experimentally to living wild-type crops; (e) summarizes a mathematical model which incorporates the measured selective intensities and other key variables and which describes the rate of increase in domestic-type mutants in early populations of wild-type cereals under specific combinations of primitive husbandry practices; (f) considers why very early cultivators should have used those husbandry methods which, we suggest, led unconsciously to the domestication of wild wheats and barley; and (g) considers whether these events are likely to leave archaeologically recognizable traces.     

Wild lentil and chickpea harvest in Israel: bearing on the origins of Near Eastern farming

Several small seeded plants were domesticated as grain crops in the Near East and other domestication centers. In this study we investigate the potential of small seeded wild lentils, and chickpea as a food source for hunters-gatherers. The yield potential and the return in terms of grams of seeds per hour of collection time were evaluated in several wild populations in Israel. The yield figures never exceeded 50 g/h, and in most cases were below 20 g/h. These data reaffirm Ladizinsky's claim that wild lentils are unlikely to have been a staple resource for hunter-gatherers prior to plant domestication. The result presented herein may be significant vis-a-vis the role attributed to small seeded (‘inefficient’) plants in the Broad Spectrum hypothesis concerning late Paleolithic, pre-agricultural societies. It may also contribute to a more careful interpretation of plant remains recovered from pre-agricultural sites.     

Wild or domesticated: DNA analysis of ancient water buffalo remains from north China

Recent zooarchaeological studies on water buffalo (Bubalus sp.) remains from China and south Asia question the traditional view that water buffalo were first domesticated in Neolithic China over 7000 years ago. The results from several recent population genetic studies of modern domesticated buffalo (Bubalus bubalis) are not consistent with each other, placing the original center of buffalo's domestication in south Asia, southeast Asia, or China. This paper reports a study using an ancient DNA approach to analyze water buffalo remains from Neolithic sites in north China to investigate their affinities with modern domesticated water buffalo, and to shed light on the origin of modern domesticated water buffalo in China.A 169 bp fragment of D-loop mitochondrial DNA was successfully amplified and verified for 13 of 24 bone samples obtained from seven archaeological sites along the Wei River valley in Shaanxi Province, China. The bone samples which yielded positive DNA can be dated to 8000–3600 cal. BP. The phylogenetic analysis of the obtained DNA sequences along with modern water buffalo sequences indicated that the ancient water buffalos were not the direct ancestor of modern domesticated water buffalo. However, the phylogenetic analysis, along with BLAST searches of these ancient DNA sequences, did demonstrate their relatedness to water buffalo more so than to any other bovid species, confirming the existence of indigenous wild (but now extinct) water buffalo species (B. mephistopheles) in ancient China.The DNA analysis of these ancient remains failed to establish direct links between modern domesticated water buffalo (B. bubalis) and indigenous water buffalo (B. mephistopheles) from ancient China. If further DNA studies of more ancient remains from other regions of China confirm the observation of solely indigenous water buffalo species in ancient China, it would suggest modern water buffalo might not have been first domesticated in China.     

On the Origins and Dissemination of Domesticated Sorghum and Pearl Millet across Africa and into India: a View from the Butana Group of the Far Eastern Sahel

Four decades have passed since Harlan and Stemler (1976) proposed the eastern Sahelian zone as the most likely center of Sorghum bicolor domestication. Recently, new data on seed impressions on Butana Group pottery, from the fourth millennium BC in the southern Atbai region of the far eastern Sahelian Belt in Africa, show evidence for cultivation activities of sorghum displaying some domestication traits. Pennisetum glaucum may have been undergoing domestication shortly thereafter in the western Sahel, as finds of fully domesticated pearl millet are present in southeastern Mali by the second half of the third millennium BC, and present in eastern Sudan by the early second millennium BC. The dispersal of the latter to India took less than 1000 years according to present data. Here, we review the middle Holocene Sudanese archaeological data for the first time, to situate the origins and spread of these two native summer rainfall cereals in what is proposed to be their eastern Sahelian Sudan gateway to the Red Sea and the Indian Ocean trade.     

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.     

High-Altitude Agro-Pastoralism in the Kyrgyz Tien Shan: New Excavations of the Chap Farmstead (1065–825 cal b.c.)

ABSTRACT

The highlands of Central Asia posed considerable challenges to early agriculturalists, yet the processes of human subsistence strategies there remain poorly understood. In this paper, we present results from the excavation of the Chap in Kyrgyzstan. The recovery of a rich macrobotanical assemblage consisting of several crop species and crop processing debris, together with skeletal remains of pastoral livestock, indicate a localized agro-pastoral complex at 2000 masl dating to 1065–825 cal b.c. Aerial photogrammetry, magnetometry, and topographic modeling reveal local irrigation systems, while stone artifacts are linked with cultivation and crop processing. Furthermore, the ceramic assemblage reveals a local production tradition and stylistic similarities with communities of neighboring regions. Overall, data from Chap contribute to a new understanding of human ecology and agricultural development in the mountains of Central Asia, suggesting that domesticated plants and animals were integral for the intensive occupation of high-elevation valleys in Central Asia.     

The Beasts At Large – Perennial Questions and New Paradigms for Caribbean Translocation Research. Part II: Mammalian Introductions in Cultural Context

Looking to clarify outstanding questions about human-animal dynamics in the pre-Columbian Caribbean, archaeologists have recently renewed investigation into the sociocultural context of mammal translocations to the islands. In this second instalment of a three-article series, I examine Amerindian ethnophoresy, that is, the process of anthropogenic species dispersal and its associated cultural practices, drawing on archaeological, ethnographic, and ethnohistoric evidence. Building on the ethnozoogeographic baselines established in Part I, I consider the tangible and intangible roles of introduced mammals, with particular attention given to subsistence, status, symbolic and ritual dimensions. I discuss enduring speculation over the management and incipient domestication of these species and its broader significance. Collectively, these topics are important because they inform explanation of the cause, extent and consequences of non-native animal introductions and allow us to understand translocation as an adaptive response to the natural and cultural environment. I conclude that resolution of the managed/domesticated status of non-native animals, in particular, constitutes the most critical research area in Caribbean ethnophoresy since this bears directly on the environmental impact and ecological legacy of mammal introductions in the region. This last topic is addressed in Part III of the series.     

从龙虬庄遗址个案看史前家猪饲养与农业发展的相关性

一般而言,农业的发展会促进家猪饲养业的相应发展,但龙虬庄遗址个案研究则展示了另一种相关性。该遗址周围相对丰富的野生动物资源在弱化人们对家猪饲养的依赖方面扮演了重要角色,这从更深的层次上印证了家畜饲养的被动发展的本质。龙虬庄遗址个案还显示了较强的区域代表意义。     

Reconstruction of diets based on the Δ15N values of individual amino acids at three sites in Sichuan,China

This study analyzes the nitrogen isotope composition of individual amino acids in collagen extracted from human bone samples from the Gaoshan, Yingpanshan, and Xinyicun sites in Sichuan, where the isotope baseline is unavailable or incomparable with the isotopic data derived from human remains. It aims to understand the food compositions of the inhabitants at these sites, spanning the period from the late Neolithic to the middle Bronze Age, during which time agriculture and domestication of animals were introduced to the region and became increasingly important. The δ¹⁵N values of two amino acids, phenylalanine (δ¹⁵N_Phe) and glutamic acid (δ¹⁵N_Glu), indicate that the peoples on the Chengdu Plain mainly consumed terrestrial foods. The contribution of aquatic resources to their diet was limited. A possible explanation for the low dependence on aquatic foods is that the developed agriculture and domestication of animals offered sufficient foods. Such subsistence economies and dietary patterns were shaped in the early Baodun period (ca. 2,500–2000 BCE) at the latest and did not seem to change when transiting to the Bronze Age. This study also assesses the significance of these subsistence practices in supporting the social development of the Chengdu Plain.
