中国稻作起源的动因

本文依据中西方学者对农业起源研究的成果,对中国稻作起源的动因进行了探讨.认为中国的稻作起源于长江中游偏南的武夷山及南岭一线以北的生态脆弱带,始于距今12000年前的旧石器时代向新石器时代过渡期,生态环境的变迁是稻作起源的主要诱因,解决人口增长的压力是稻作起源的直接动因,而人类的生产力及技术水平的进步则是稻作起源的动能.这三者相互作用的结果催生了稻作农业的产生.     

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。     

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.     

Modelling the Neolithic transition in a heterogeneous environment

The Neolithic transition, involving the change of subsistence from foraging to agriculture, can fruitfully be modelled mathematically, as, e.g., in the three-population model of Aoki et al. (1996). Here that model is modified to include some features of population dynamics in a realistic, two-dimensional environment, and including population pressure, competition for resources between farmers and foragers, and the dependence of the population carrying capacities and diffusivities on the environmental conditions. This modified model allows for the survival of foragers in regions where environmental conditions do not favour farming. The model is tentatively applied to the Indian subcontinent, which is a complicated example of this transition involving multiple domestication centres. The results are briefly compared with published archaeological data.     

Gazelle exploitation in the early Neolithic site of Motza,Israel: the last of the gazelle hunters in the southern Levant

We studied the faunal remains from the Early and Middle PPNB site of Motza, Judean Mts., Israel, in order to gain insight into the economic basis prior to livestock husbandry, with a focus on gazelle hunting. Taphonomic analysis showed that bone preservation at the site was excellent. The subsistence economy in Motza was based on a broad spectrum of hunted species, with mountain gazelle (Gazella gazella) as the dominant prey, similar to many Epipalaeolithic and Pre-Pottery Neolithic sites in the southern Levant. We studied gazelle exploitation patterns, in order to learn about the interaction of humans with this species prior to ungulate domestication. Analysis of the demography of the gazelle herd, which included aging and sexing, revealed no age preferences and no selective culling. Moreover, the PPNB gazelle population of Motza does not exhibit allometric changes in morphology, that are allegedly correlated to increased hunting pressure on gazelle populations prior to livestock domestication.     

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.     

Was the Dog Locally Domesticated in the Danube Gorges? Morphometric Study of Dog Cranial Remains From Four Mesolithic–Early Neolithic Archaeological Sites by Comparison With Contemporary Wolves

In this article, we test a hypothesis about local dog domestication in the Danube Gorges of the central Balkans in the course of the Mesolithic period. Morphometric features of dog mandibles and teeth from Mesolithic–Early Neolithic sites of Vlasac, Padina, Lepenski Vir, and Hajdučka Vodenica have been analysed and compared with recent wolves from the central Balkans. Decrease in size and changes in proportions of dog's dental features were tracked diachronically. We identified specimens which manifested mixed wolf/dog features. Such specimens originate from the Early Mesolithic contexts, the time when a decrease in size began. On the basis of this pattern, we suggest that dog domestication may have taken place in the Danube Gorges during the Early Mesolithic (ca 9500–7500 cal. bc ). The reduction of size continued throughout Late Mesolithic (ca 7500–6300 cal. bc ), but there were still individuals that might be regarded as ‘transitional’ in comparison with wolves on account of their size, and a distinct difference in size between wolves and dogs did not develop. Accordingly, if local domestication was in progress here, the domestication process might have lasted for more than just few generations and even several millennia.

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.     

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.     

The first hair remains from an aurochs (Bos primigenius) and some medieval domestic cattle hair

A new find of hair on a 13th century aurochs bone from Pultusk, Poland provides the first hair measurements from what is certainly a wild ox and supports previous suggestions regarding the hair of early domestic cattle. Two rare samples of British medieval cattle hair provided more measurements throwing light on coat changes since domestication.     

陕西近年出土的水牛遗存及中国本土水牛的进化

本文分析了陕西渭河流域新出土的更新世杨氏水牛和全新世的圣水牛头骨和颅后骨,并对比了其他地区出土的水牛标本。作者根据新的资料讨论了水牛种属的分类、进化及驯化问题。渭河流域在更新世时期至少有圣水牛,它很可能是更新世短角水牛的后代。它在进入全新世之前形体也许有所减小;但全新世早、中期(距今8000-3000年),没有迹象表明它的形体有所缩小,圣水牛的这一变化应该不是受人类活动影响(如驯化)的结果,但是否为适应气候变化而发生还有待研究。     

Early Neolithic pig domestication at Jiahu,Henan Province,China: clues from molar shape analyses using geometric morphometric approaches

The zooarchaeology of pig domestication in China is a challenging task due to its wild boar ancestors being widespread throughout Eurasia. However using geometric morphometric approaches on molar tooth (M₂), shape and size variations, from modern and Neolithic suids, using Yangshao pigs as a surrogate for the Neolithic domestic form, we have addressed the identification of morphological change during the early step of domestication in three early Neolithic sites where claims of pig domestication have been made. Phenetic relationships here have revealed clear and interpretable phenotypic signatures in the samples of modern and Neolithic pigs; which provide evidence for pig domestication at the site of Jiahu from at least 6600 BC cal., re-establishing the Yellow River region as one of the earliest centre of independent Chinese pig domestication.

江苏泗洪韩井遗址水稻驯化的植硅体证据及相关问题

韩井遗址顺山集文化一期由洼地和水沟组成的水稻田,很可能是目前发现的最早与人类驯化水稻相关的遗迹,植硅体分析也在一定程度上对这一论断给予支持。从顺山集文化一期到二期,韩井遗址均以水稻双峰型植硅体居多,而且其百分比和浓度(均值)均呈现增多的态势;水稻扇型和横排哑铃型植硅体表现出相反的规律。与同时期顺山集遗址相比,韩井遗址的水稻扇型植硅体尺寸偏小。水稻扇型植硅体鱼鳞状纹饰个数和水稻双峰型植硅体形态测量用于水稻驯化程度的判定上,表现出非协同性。陶胎中掺入破碎稻壳是韩井遗址水稻栽培与驯化实践的又一反映。     

Understanding the Carbonization and Preservation of Sunflower and Sumpweed Remains

Abstract

In this paper, I describe important chemical and physical properties of carbonized sunflower and sumpweed achenes and examine how those properties influence both the preservation and interpretation of these remains. Specifically, I designed a series of laboratory experiments to understand better the changes in chemical composition associated with the carbonization of achenes and to evaluate more thoroughly the use of measurements as a method to identify morphological changes linked with domestication. I also discuss how other factors, including the natural environment and processing technologies, may affect achene size and preservation.     

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.     

Mammalian fauna from Palaeolithic sites in the Upper Yenisei River basin (southern Siberia): Review of the current zooarchaeological evidence

The palaeontological data on mammal remains from two Middle Palaeolithic (ca. 125 000 years ago – 27 200 BP) and 34 (ca. 34 000–12 000 BP) Upper Palaeolithic cultural complexes in the upper part of the Yenisei River basin (southern Siberia) are considered. General features of the faunal assemblages are established. Several issues are discussed, including (a) changes in species composition through time and palaeoenvironmental implications of the zooarchaeological records; (b) patterns of human exploitation (hunting) of mammals; (c) issue of mammoth hunting and (d) possibility of domestication of dog in the late Upper Palaeolithic in the Yenisei River basin.

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.     

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。     

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.
