Morphometric Analysis of Sus Remains from Neolithic Sites in the Wei River Valley,China, with Implications for Domestication

Size variation of Sus remains within and between sites is examined for the Neolithic sites in the Wei River valley in China. The coefficient of variation [V] for pig measurements at the sites of Wayaogou, Quanhucun and Jiangzhai was calculated, and we observed patterns that show evidence of two populations of different‐size pigs, supporting the likelihood that both wild and domestic pigs were present. Also, size reduction of pigs can be traced within the Neolithic‐early Bronze Age archaeo‐faunal sequence of the Wei River valley. This size reduction was accompanied by an increase of coefficients of variation through the Neolithic. Both of these trends were probably the consequences of pig domestication, and the morphometric differences probably provide evidence for the different stages of pig domestication in this region.

Early Pig Management in the Zagros Flanks: Reanalysis of the Fauna from Neolithic Jarmo,Northern Iraq

In this paper, we present a reanalysis of pig (Sus scrofa) remains from the Neolithic site of Qalat Jarmo, originally excavated in the 1940s and 1950s. Employing modern zooarchaeological techniques, not available during the initial analyses, we explore the nature of swine exploitation strategies and demonstrate that pigs were most likely managed by the early 7th millennium (Pottery Neolithic) and perhaps earlier. Comparing biometric data with those from other sites in the region, we show that the Jarmo pigs exhibit evidence for size decrease associated with intensive management, but had not yet achieved the degree of dental or post‐cranial size reduction seen in later Neolithic domestic populations. Although samples from the earliest (Pre‐Pottery) occupation of the site are small, there is some evidence to suggest that domestic pigs were present at Jarmo as early as the late 8th millennium cal. bc . In either case, Jarmo likely represents the earliest appearance of pig husbandry along the Zagros flanks, and we discuss the mechanisms by which Neolithic technologies, including domesticated animals, spread to new regions. This project emphasises the value of curated faunal assemblages in shedding new light on the spread of Neolithic economies. Copyright © 2013 John Wiley & Sons, Ltd.     

The late adoption of cattle and pig husbandry in Neolithic Central Turkey

This paper summarizes and interprets zooarchaeological evidence for cattle and pig domestication in Neolithic Central Anatolia. Biometric and demographic data indicate that domestic cattle first appear in the region in the late seventh millennium cal BC while domestic pigs are not evident until the mid fifth millennium. This places the origins of cattle and pig husbandry in Central Anatolia considerably later than in neighboring regions. Reasons for this delay in the spread of productive animal husbandry practices are explored.     

Pig domestication and husbandry practices in the middle Neolithic of the Wei River Valley,northwest China: evidence from linear enamel hypoplasia

Linear enamel hypoplasia is a physical deficiency occurring during the process of enamel formation and it is visible on the crowns of mammal teeth. It can be used to trace physical stresses during life. In this study, linear enamel hypoplasia in samples of pigs from three Neolithic sites in the Wei River valley (China) were recorded and analysed, to investigate the status of pigs at these sites, their living conditions, and furthermore to explore husbandry strategies for pigs during the Neolithic in the valley. The results suggest a domesticated status for pigs in the Neolithic and early Bronze Age. Also the frequency of LEH occurrence for the pigs corroborates a presumed intensification processes of pig husbandry, and the presence of environmental fluctuations during the period are considered. Some evidence also points to the fact that for pig, spring farrowing was the most common reproductive strategy in the Neolithic and early Bronze Age in this region.     

Re-evaluating the history of the wheat domestication gene NAM-B1 using historical plant material

The development of agriculture is closely associated with the domestication of wheat, one of the earliest crop species. During domestication key genes underlying traits important to Neolithic agriculture were targeted by selection. One gene believed to be such a domestication gene is NAM-B1, affecting both nutritional quality and yield but with opposite effects. A null mutation, first arisen in emmer wheat, decreases the nutritional quality but delays maturity and increases grain size; previously the ancestral allele was believed lost during the domestication of durum and bread wheat by indirect selection for larger grain. By genotyping 63 historical seed samples originating from the 1862 International Exhibition in London, we found that the ancestral allele was present in two spelt wheat and two bread wheat cultivars widely cultivated at the time. This suggests that fixation of the mutated allele of NAM-B1 in bread wheat, if at all, occurred during modern crop improvement rather than during domestication. We also discuss the value of using archaeological and historical plant material to further the understanding of the development of agriculture.     

Domestic Pigs in Africa

The history of African pig breeds is still controversial due to the relative scarcity of archaeological and genetic data clarifying their origins. While these breeds might descend from Near Eastern pigs entering the continent via Egypt during the Neolithic, Africa may be a primary domestication locus for pigs, as indicated for other species such as cattle and donkeys. In this regard, characterisation of the mitochondrial gene pool of African pig breeds has revealed a very low frequency of Near Eastern alleles, suggesting that, if Fertile Crescent pigs played a part in the foundation of African breeds, their genetic signature has been substantially erased. Interestingly, genetic analysis of western and eastern African pig breeds has revealed a strong phylogeographic pattern, with the latter harbouring Far Eastern alleles at high frequencies. This finding is consistent with data obtained for chickens and confirms that livestock was transported in ancient times, from the Far East to Africa as a consequence of the Indian Ocean trade. European colonisation of Africa also involved the introduction of exotic swine breeds such as Iberian pigs. The confluence of the highly divergent European and Far Eastern Sus scrofa gene pools contributed to significantly enrich the genetic reservoir of African swine breeds, favouring their adaptation to environmental conditions that are often harsh. Conservation of this genetic legacy will be of utmost importance to ensure the prosperity of current resource-based subsistence farming systems in Africa.     

The sheep of early jericho

A re-examination of the ruminant remains from the excavations of the Jericho Tell has shown that sheep were certainly present, both in the pre-pottery Neolithic A levels and in the pre-pottery Neolithic B levels. Details are given of the osteology of the fourteen bones that have been identified as sheep and the implications of their origin in the context of early domestication are discussed.     

Feeding Management Strategies among the Early Neolithic Pigs in the NE of the Iberian Peninsula

The socio‐economic relevance of domesticated animals during the Early Neolithic in the Iberian Peninsula is indisputable, yet we essentially know little about the way they were managed. Among domesticated animals, pig (Sus domesticus ) was a common food source, and previous studies have shown the potential of stable isotopes for assessing variability in pig diet in relation to husbandry practices. Nevertheless, this approach has never been applied to the earliest pigs in the Iberian Peninsula. We analysed the carbon and nitrogen stable isotope composition of pig bone collagen from several Early Neolithic sites in the NE Iberian Peninsula. While pig δ¹³C values were similar across different populations, there were significant differences in δ¹⁵N values between sites. These are attributed to different pig husbandry systems, which may reflect distinct social and spatial organisation and interaction with environmental conditions during the Early Neolithic in this region.

A Metrical Analysis of a Collection of Modern Goats (Capra hircus aegargus and C. h. hircus) from Iran and Iraq: Implications for the Study of Caprine Domestication

A critical comparison of two commonly used markers of initial animal domestication, size reduction and demographic profiling, is presented. A metrical analysis of a large collection of modern wild and domestic goats (Capra hircus aegargus and C. h. hircus) from Iran and Iraq clearly demonstrates that sex is by far the most significant factor affecting size in goats. In all post-cranial bones examined, those of males, even the unfused bones of males over 1 year of age, are absolutely larger than the bones of females. Region also plays a significant role in the size of these animals, but domestic status seems to have little impact. Similarly, a re-analysis of archaeological assemblages from Upland Sites the eastern fertile crescent shows no evidence of population-wide size reduction over a period that encompasses the transition from hunting to herding goats in the region, from the Middle Palaeolithic to the Early Neolithic. The apparent rapid reduction in the size of caprines during the early phases of domestication noted in earlier studies is likely attributable to a shift in the sex ratio of the adult breeding population of managed herds towards female domination, plus the differential destruction and loss of the bones of male animals killed at younger ages, as well as biases introduced by standard methodological practices. Building on the earlier work of Hesse, and using the empirical understanding of the factors influencing size in modern goats gained in this study, a new approach is proposed that combines both size and long-bone fusion data to construct high resolution, sex-specific age profiles of male and female goats that can be used to detect the hunting to herd management transition which marks the initial stages of the domestication process.     

Mitochondrial DNA Analysis of Ancient Domestic Goats in the Southern Caucasus: A Preliminary Result from Neolithic Settlements at Göytepe and Hacı Elamxanlı Tepe

This study presents preliminary results of mitochondrial DNA analyses of modern and ancient domestic goats in the southern Caucasus in order to examine their phylogenetic relationship with modern and ancient goats. For this purpose, seven ancient samples were obtained from two early agricultural villages in west Azerbaijan (Göytepe and Hacı Elamxanlı tepe, dated to ca. 6000–5500 cal bc , the Pottery Neolithic period), in addition to five modern goat samples in the same region. In the study, mitochondrial DNA segments of the control region (216 bp for the Neolithic samples and 481 bp for the modern samples) were amplified, and phylogenetic analyses were performed using previously published reference DNA sequences. As a result, all the haplotypes found in this study were grouped in the haplogroup A of goats. The finding of the haplogroup A among domestic goats in the southern Caucasus in the early sixth millennium bc can be interpreted as part of the geographic expansion of this lineage from the areas of initial domestication to surrounding areas that include also South and Southeast Europe. In the southern Caucasus, the haplogroup A probably continued to be a major lineage among domestic goats since their emergence in this area to the present. In contrast, this lineage has not been detected among local wild goats including Capra aegagrus , indicating the external origin of domestic goats. This possibility is consistent with archaeological records that indicate sudden appearance of agricultural lifeways in the southern Caucasus and cultural connections with northern Mesopotamia.

Combining Odontochronology,Tooth Wear Assessment,and Linear Enamel Hypoplasia (LEH) Recording to Assess Pig Domestication in Neolithic Henan,China

Mandibles of Sus scrofa (wild boar/pig) from ritual pits H160 and H208 of Longshangang, a Late Yangshao Neolithic site in Xichuan County, Henan, were analyzed for evidence of domestication. Three methods of dental analysis were applied: odontochronology, tooth wear assessment, and linear enamel hypoplasia (LEH) recording, which provide age at death, season of kill, and season of birth data. We investigate whether: (i) the LEH height frequencies on the second molars of the mandibles correspond with the possibility of double farrowing and (2) double farrowing is supported by the season of and age at slaughter data. If so, these data suggest a substantial degree of human management of suids at the site. 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。     

Beyond Boundaries: Nature,Culture and a Holistic Approach to Domestication in the Levant

The main objective of this paper is to suggest an alternative approach for the investigation of domestication in the Levant. First, basic data regarding domestication in the Levant are presented. Then the various traditional approaches towards domestication in the prehistoric Levant, labeled (1) environmental, (2) social and anthropological, and (3) cognitive, are briefly reviewed. This discussion forms the basis for a proposal of a “holistic approach,” in which domestication is regarded as a long-term, multidimensional and multirelational phenomenon, including many elements—such as plants, animals, humans, material culture and ancestors—with increasing human manipulation of these various constituents. After a presentation of the theoretical framework, a growth metaphor is used to reconstruct the process of domestication (ca. 20,000–6500 B.P.) as a number of phases: (1) germination in the Kebaran; (2) development in the Early Natufian; (3) retreat/dormancy in the Late/Final Natufian; (4) growth in the Pre-Pottery Neolithic A; (5) florescence in the Early- and Middle Pre-Pottery Neolithic B: (6) further development in the Late Pre-Pottery Neolithic B; (7) dispersal in the Final Pre-Pottery Neolithic B and the Pottery Neolithic. In each of these phases, relations between the various elements are dealt with, special attention being paid to symbolical relations, as evidenced by “art” and ritual.     

Analyzing the process of domestication: Hagoshrim as a case study

Recent excavations at the Neolithic site of Hagoshrim, northern Israel, have yielded a large assemblage of skeletal fragments, representing mostly caprines, cattle and pigs. The three layers of the site's occupation span approximately 2000 years of a crucial period in the domestication of these taxa in the southern Levant, including Pre-Pottery Neolithic C (Layer 6, 7562 ± 85 BP and 7735 ± 55 BP) and the Pottery Neolithic cultures, Jericho IX (Layer 5, 6725 ± 120 BP) and Wadi Raba (Layer 4, 6505 ± 120 BP). Therefore, this site provides an outstanding opportunity to study the process of domestication in a comparative manner, both across taxa and through time. We used kill-off patterns, size reduction and changes in body proportions, and introduced statistical methods to discern the different stages of the domestication process for each taxon. Pig remains reflect simultaneous changes at the end of the 7th millennium BP: kill-off patterns, size and proportions of cranial and post-cranial elements all change between Layer 5 and 4 with no significant changes between Layer 6 and 5. Gradual changes—both between Layer 6 and 5 and between Layer 5 and 4—were found only for cattle, while caprine remains exhibit no changes throughout the site's occupation. These results can be explained in light of the differences between the taxa in terms of their life history strategies, among other things, that can be viewed as pre-adaptations to domestication.     

Agricultural Origins and Frontiers in South Asia: A Working Synthesis

The accumulation of recent data from archaeobotany, archaeozoology and Neolithic excavations from across South Asia warrants a new overview of early agriculture in the subcontinent. This paper attempts a synthesis of these data while recommending further systematic work and methodological developments. The evidence for origins and dispersals of important crops and livestock from Southwest Asia into South Asia is reviewed. In addition evidence for indigenous plant and animal domestication in India is presented. Evidence for probable indigenous agricultural developments in Gujarat, the Middle Ganges, Eastern India, and Southern India are reviewed. An attempt is made to highlight regions of important frontiers of interaction between early farmers and hunter-gatherers. The current evidence suggests that the Neolithic trajectories in different parts of South Asia differ from each other. Indigenous centers of plant domestication in India also differ from the often discussed trajectory of Southwest Asia, while suggesting some similarities with agricultural origins in Africa and Eastern North America as well as secondary agricultural developments on the peripheries of Eurasia.

Pig exploitation in the southern Kanto region,Japan

This study investigates changes in past human and animal relationships by focusing on pig (Sus scrofa) remains excavated from archaeological sites in southern Kanto, Japan. Pigs and humans have had a close relationship since prehistoric times and the process of change in this relationship, including possible domestication, is one of the major issues in Japanese zooarchaeology. This study attempts to gain a better understanding of the nature of past interaction between humans and pigs by investigating their relative importance compared with other vertebrate remains, kill‐off patterns, and changes in their size and shape at these sites. The materials used for this study date from the Earliest to Final Jomon (ca. 10,000–2500 BP), Yayoi (ca. 2500–1700 BP) and Kofun (ca. 1700–1300 BP) periods. The relative proportions of pigs were calculated to show the overall trend of pig exploitation in each site. Age at death was obtained based on the state of tooth eruption. Bucco‐lingual crown measurements were taken on the third and fourth premolars and on each cusp of the first and second molars of the mandible, and the logarithmic ratio technique was then applied to these data. The age structure of Sus varies between different sites in the Jomon Period, and significant changes were observed in the Yayoi and Kofun Periods. A decrease in the relative proportion of pigs in the faunal assemblages was observed from Jomon to Kofun. Three major differences were observed in the size of pigs. The overall size of pigs significantly increased from Early to Middle Jomon, whilst a decrease in size occurred in the Yayoi Period. Finally, overall size increased significantly during the Kofun Period. Together with the archaeological evidence—such as the ritual burial of pigs accompanying human burial—we suggest that the interaction between pigs and humans became gradually stronger at some sites during the Late Jomon Period, and the relationship intensified in the Yayoi Period.

A Pilot Study in Odontochronology for the Pig Domestication Question in North‐Central China

In this paper, we report results of the pilot study in which we apply skeletochronological analysis of teeth to a collection of modern Chinese wild boar (Sus scrofa) of known age and date of death. This is the first time that odontochronology has been applied to suids in China. This work allowed us to establish parameters for subsequent analysis of a limited number of Neolithic‐aged Sus (wild boar and possible early domesticated pig) samples from Henan Province. The goal of the research is to contribute to the ongoing reconstruction of Neolithic dietary, health and economic patterns along the Yellow River. Our results are encouraging in that regular seasonal growth patterning is observed in the northern control sample, which is from the same region as our archaeological investigation.

Identifying donkey domestication through changes in cross-sectional geometry of long bones

The initial phases of donkey domestication are difficult to identify in the archaeological record due to late and inconsistent changes in morphology and body size in the earliest domestics. Use of donkeys for load carrying and the management of captive herds resulted in a distinctive behavioral shift away from the free-ranging speed and mobility characteristic of wild asses toward slower, more steady pacing. Given the ability of bone to adapt to its mechanical environment, bone remodeling in the limbs of wild asses and donkeys are evaluated using cross-sectional geometry to determine whether weight bearing or locomotor differences between the wild and domestic forms may be used to recognize early domestication. Cross-sectional data were collected on the humeri, radii, metacarpals and metatarsals of eight wild ass and six donkey skeletons. Wild ass forelimbs have greater overall strength and more cylindrical humeral diaphyses, indicating better resistance to a varied locomotor repertoire. These results demonstrate that analyses of shaft geometry can provide information on changes in locomotor behavior during domestication. Our finding that shifts in gait had greater effects on the morphology of early domestic donkeys than did load-carrying places a new emphasis on understanding selection for gait changes in domestication dynamics.     

GEOGRAPHICAL PATTERNS IN BIOLOGICALLY AVAILABLE STRONTIUM,CARBON AND OXYGEN ISOTOPE SIGNATURES IN PREHISTORIC SW GERMANY*

In order to interpret strontium and oxygen isotope values in Neolithic human skeletons analysed previously, we begin to map the biologically available strontium, carbon and oxygen isotopic signatures of prehistoric southern Germany by analysing tooth enamel of pigs from archaeological sites distributed around the region. The mapping shows a marked upland–lowland difference in biologically available ⁸⁷ Sr/ ⁸⁶ Sr values, ranging between 0.7086 and 0.7103 in the sedimentary lowlands, and from 0.710 to as high as 0.722 in the crystalline uplands of the Odenwald, the Black Forest and the Bavarian Forest. In addition, carbon isotopes in the carbonate fraction of pig enamel were generally about 1–2 more enriched in ¹³ C in the uplands. Despite the expected depletion of ¹⁸ O with altitude, oxygen isotopes in pig enamel showed little correlation with site altitude, although for pig samples not older than the Iron Age there was some geographical correlation withδ¹⁸O patterns in modern precipitation.     

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.
