Previous evaluations of the potential advantage of farming over foraging have been based on experimental harvesting of wild cereals in Near Eastern ecosystems. The highly successful combination of cereals and legumes, “the Near Eastern crops assemblage”, is considered a natural choice due to the complementary nutritional value of the two crop types. Yet, legumes were rarely referred to in models describing early farming and the transition from foraging to farming. Wild legumes differ from wild cereals in several attributes pertaining to domestication, including population density (patchy vs. dense), growth habit (indeterminate vs. determinate), dispersal units (camouflaged seeds vs. awned spikelets), seed dormancy (90–80% vs. 50%), and year to year establishment (erratic vs. regular). We have analyzed the yield potential of three wild pea species (Pisum elatius, P. humile, and P. fulvum) in several ecosystems in Israel. All three pea species have patchy distribution patterns and the yield potential of the wild populations is highly variable. A harvest rate of 0.6–610 grams (calculated per collector) of clean dry grain per hour of harvest time was estimated. Among the three species studied the one adopted for domestication appears to be the least productive. This suggests that the potential productivity of wild peas was not the only or even the major consideration for domestication.  相似文献

Harvest experiments of wild crop relatives are essential for our understanding of the biology of wild plants embodied in the economy of ancient forager communities. Most of the previous experimental harvest reports spanned a single season and therefore are unable to address questions concerning long-term yield potential. Herein we report on six consecutive harvest seasons taking place at four sites in Israel that harbour wild pea populations: three typical Pisum fulvum sites and one typical Pisum elatius site. Three out of the four sites showed no indication of a decline in grain yield as a result of repeated harvest and the removal of a considerable portion of mature seeds. Site-specific factors seem to have a strong influence on the grain yield as no seasonal yield similarity was observed between adjacent and ecologically similar sites harbouring the same wild pea taxon. The erratic year-to-year wild pea yield we observed calls for a reassessment of the presumed role of grain legume species in Near Eastern hunter–gatherers' diet. Combined with published data on cultivation of wild pea, our results are inconsistent with models suggesting protracted domestication of Near Eastern grain legumes or with the preliminary attempts to apply Niche Construction Theory to the study of plant domestication in the Near East.  相似文献

Particular geographic features of the Mediterranean Levant underlie the subsistence patterns and social structures reconstructed from the archaeological remains of Epi-Paleolithic groups. The Kebaran, Geometric Kebaran, and Mushabian complexes are defined by technotypological features that reflect the distributions of social units. Radiocarbon dating and paleoclimatic data permit us to trace particular groups who, facing environmental fluctuations, made crucial changes in subsistence strategies, which, in the southern Levant, led to sedentism in base camps on the ecotone of the Mediterranean woodland-parkland and the Irano-Turanian steppe. The establishment of Early Natufian sedentary communities led to a regional change in settlement pattern. The relatively cold and dry climate of the eleventh millennium B.P. forced Negev groups into a special arid adpatation. The early Holocene onset of wetter and warmer conditions favored the earliest Neolithic (PPNA) development of village life based on the cultivation of barley and legumes, gathering of wild seeds and fruits and continued hunting.  相似文献

This research aims to shed light on the early stages of agricultural development in Northern Africa through the analysis of the rich macro-botanical assemblages obtained from Ifri Oudadane, an Epipalaeolithic–Early Neolithic site from North-East Morocco. Results indicate the presence of domesticated plants, cereals (Hordeum vulgare, Triticum monococcum/dicoccum, Triticum durum and Triticum aestivum/durum) and pulses (Lens culinaris and Pisum sativum) in the Early Neolithic. One lentil has been dated to 7611 ± 37 cal BP representing the oldest direct date of a domesticated plant seed in Morocco and, by extension, in North Africa. Similarities in both radiocarbon dates and crop assemblages from Early Neolithic sites in Northern Morocco and the Iberian Peninsula suggest a simultaneous East to West maritime spread of agriculture along the shores of the Western Mediterranean. Wild plants were abundantly collected in both the Epipalaeolithic and the Early Neolithic periods pointing to the important role of these resources during the two periods. In addition to fruits and seeds that could have been consumed by both humans and domesticated animals, fragments of esparto grass (Stipa tenacissima) rhizomes have been identified. This is a western Mediterranean native plant that may have been used as a source of fibres for basketry.  相似文献

The Middle Neolithic Pitted Ware Culture on the Baltic Sea islands comprised a common identity distinguished, in part, by an almost exclusively marine diet. Based on evidence from the first stable isotope analysis on Pitted Ware skeletal material from the Eastern Central Swedish mainland, we suggest that this identity was shared by PWC groups in the archipelago of the west side of the Baltic. Fifty-six faunal and 26 human bone and dentine samples originating from the Pitted Ware site Korsnäs in Södermanland, Sweden were analysed, and the data clearly shows that the diet of the Korsnäs people was marine, predominantly based on seal. The isotope data further indicate that the pig bones found in large quantities on the site emanate from wild boar rather than domestic pigs. The large representation of pig on several Pitted Ware sites, which cannot be explained in terms of economy, is interpreted as the results of occasional hunting of and ritual feasting on wild boar, indicating that the animal held a prominent position, alongside seal, in the hunting identity and cosmology of the Pitted Ware people. Further, eleven new radiocarbon dates are presented, placing the Korsnäs site, with a large probability, within Middle Neolithic A.  相似文献

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.

The archaeological record of dry rockshelters in the Red River Valley of eastern Kentucky contains botanical remains of several weedy annual seed-bearing plants that point to the independent development of agriculture during the Late Archaic and Early Woodland Period. The objective of this study is to gather quantitative data through the chemical and physical analysis of soils collected within a valley transect to gain insights into landscape processes and soil fertility that may have played a role in the early development of plant domestication and the location of garden plots in relation to rock shelter sites in the upper Cumberland Plateau region of eastern Kentucky. Soils on upland benches formed in limestones have soil fertility values that are comparable to fertile floodplain soils. Upslope outcrops of calcareous bedrock are contributing basic cations to these bench soils. Additionally, in comparison to other landscape positions these upland soils have high levels of organic carbon, available P and greater C:N ratios. Soil morphology, radiocarbon dates, and archaeological evidence indicate that many of the numerous earthflows and debris flows within the region are Early to Middle Holocene in age. These slides were likely generated by Mid-Holocene climatic shifts in which the frequency and intensity of summer precipitation increased across the southeastern United States. These slope failures may have contributed to the development of plant domestication by creating forest canopy gaps and disturbed soils in which weedy plants thrived.  相似文献

Current knowledge about the Mesolithic–Neolithic transition in the Central and Western Mediterranean European regions is deeply limited by the paucity of Late Mesolithic human osteological data and the presence of chronological gaps covering several centuries between the last foragers and the first archaeological evidence of farming peoples. In this work, we present new data to fill these gaps. We provide direct AMS radiocarbon dating and carbon (δ13C) and nitrogen (δ15N) stable isotope analysis were carried out on bone collagen samples of two single burials from the recently discovered open-air Late Mesolithic site of Casa Corona (Villena, Spain). The results shed new light on the chronology and subsistence patterns of the last Mesolithic communities in the Central Mediterranean region of the Iberian Peninsula. Radiocarbon results date the human remains and funerary activity of the site to 6059–5849 cal BC, statistically different from other Late Mesolithic sites and the earliest Neolithic contexts, and bridging the 500 yrs chronological gap of the Mesolithic–Neolithic transition from the area. Isotopic evidence shows that diet was based on terrestrial resources despite the proximity to the site of lagoon and marine ecosystems. This and previous isotope studies from the region suggest a lower reliance upon marine resources than for Atlantic and Cantabrian sites, although intra-regional patterns of neighbouring Mesolithic populations exhibit both fully terrestrial diets and diets with significant amounts of aquatic resources in them. We hypothesize that in the Central Mediterranean region of Spain the Late Mesolithic dietary adaptations imposed structural limits on demographic growth of the last foragers and favoured rapid assimilation by the earliest Neolithic populations.  相似文献

Direkli Cave is an Epipalaeolithic site in the central Taurus mountain range in southeastern Turkey that was used by mobile hunter-gatherer communities. The assemblage of beads from the cave, made primarily from shell (marine and freshwater) and stone, shows new evidence both that bead materials were brought to the site from the shores of the Mediterranean and that the material culture of the site has relationships to the Levant, northern Mesopotamia, and inner Anatolia. This article questions how such a bead assemblage should be interpreted in the light of existing evidence for the Near Eastern and Anatolian Epipalaeolithic and what it adds to our understanding of the better known contemporary Natufian culture of the Levant. It considers the long-distance movement of materials, interregional material cultural influences, and the way the Epipalaeolithic period is conceptualized more broadly.  相似文献

Within the framework of the French archaeological mission ‘Caucasus’, in a previous paper we have presented new geochemical analyses on geological obsidians from the southern Caucasus (Armenia, Georgia) and eastern Turkey. We present here the second part of this research, which deals with provenance studies of archaeological obsidians from Armenia. These new data enhance our knowledge of obsidian exploitation over a period of more than 14 000 years, from the Upper Palaeolithic to the Late Bronze Age. The proposed methodology shows that source attribution can be easily made by plotting element contents and element ratios on three simple binary diagrams. The same diagrams were used for source discrimination. As the southern Caucasus is a mountainous region for which the factor of distance as the crow flies cannot be applied, we have explored the capacity of the Geographic Information System to evaluate the nature and patterns of travel costs between the sources of obsidian and the archaeological sites. The role of the secondary obsidian deposits, which enabled the populations to acquire raw material at a considerable distance from the outcrops, is also considered.  相似文献

In this paper we evaluate the relative analytical capabilities of SEM-EDS, PIXE and EDXRF for characterizing archaeologically significant Anatolian obsidians on the basis of their elemental compositions. The study involves 54 geological samples from various sources, together with an archaeological case study involving 100 artifacts from Neolithic Çatalhöyük (central Anatolia). With each technique the artifacts formed two compositional groups that correlated with the East Göllü Da? and Nenezi Da? sources. The non-destructive capabilities of these methods are emphasized (albeit with certain analytical limitations in the case of SEM-EDS), suggesting important new techniques for Near Eastern obsidian provenance studies.  相似文献

Abstract

On archaeological sites where livestock dung was a major fuel source, plant material that survives digestion intact may well be preserved in the remnants of dung-fuelled fires. Preserved plant remains which were derived from dung relate to the diet of animals, and thus provide a way of investigating the agro-pastoral economies of the past. In order to improve our understanding of the taphonomic processes to which plant material is exposed to during digestion, we applied archaeobotanical methods to the analysis of dung from sheep fed a known diet of cereal and wild plant material. Two clear patterns emerge from these investigations. First, cereal material (grain or chaff) survives digestion poorly and was rarely found in the dung analysed. Second, large proportions of seeds of various wild species survive digestion in an identifiable form, probably due to their small size and/or protective coating. These findings are crucial for reliable interpretation of dung-derived plant material in archaeological settings.  相似文献

本文根据盐湖卤水的地球化学特征以及盐湖生态系统等盐湖知识和理论,结合古人对盐湖湖色和浑浊度相关记载,校正《水经·涑水注》安邑盐池文字当为"紫色澄渟,渾而不流"。该段文字反映了盐湖在特定时间段内盐度增高,而盐度变化引起盐湖生物链顶端的优势种群卤虫体内产生红色素,进而将卤水染成紫色或者深红色;同时,这些悬浮于高浓度卤水中的卤虫,极大地影响了湖水对光线的吸收和散射,带来湖水浑浊的盐湖地理现象。郦道元提取了盐湖湖表卤水湖色和浑浊度的感官性状指标,强调其在盐天然结晶前的指标作用,是传统时代汉文文献中记载结晶前高盐度卤水中湖色和浑浊度变化精度最高的文本。  相似文献

A large analytical programme involving both obsidian source characterization and obsidian artefact sourcing was initiated recently within the framework of the French archaeological mission ‘Caucasus’. The results will be presented in two parts: the first part, this paper, deals with the presentation and characterization of obsidian outcrops in the southern Caucasus, while the second presents some results obtained from a selection of artefacts originating from different Armenian sites dated to between the Upper Palaeolithic and the Late Bronze Age. The same analytical method, LA–ICP–MS (laser ablation inductively coupled plasma mass spectrometry), has been used to characterize all the studied samples (both geological and archaeological). This method is more and more widely used to determine the elemental composition of obsidian artefacts, as it causes minimal damage to the studied objects. We present in this first part new geochemical analyses on geological obsidians originating from the southern Caucasus (Armenia, Georgia) and eastern Turkey. These data enhance our knowledge of the obsidian sources in these regions. A simple methodology, based on the use of three diagrams, is proposed to easily differentiate the deposits and to study the early exploitation of this material in the southern Caucasus.  相似文献
