Crop husbandry activities and wild plant gathering,use and consumption at the EPPNB Tell Qarassa North (south Syria)

The Early Pre-Pottery Neolithic B (EPPNB) in southwest Asia is a fundamental period in research on the origins of domesticated plants. However, there are few archaeobotanical data with which to characterise the plant-based subsistence and crop husbandry activities during this time, which hinders the understanding of the factors that triggered the appearance of plant domestication. In this paper, analyses of non-woody plant macro-remains provide new insights into subsistence activities such as crop cultivation (husbandry activities and storage) and plant use (wild plant gathering and food preparation) during the EPPNB at Tell Qarassa North (south Syria). We make comparisons between Tell Qarassa North and the evidence at earlier and later periods as to how plants were used, and highlight similarities and differences in the practices attested, as well as describing some of the consequences that these plant-related activities may have had in terms of labour and social organization during EPPNB.     

Form and Function of Early Neolithic Bifacial Stone Tools Reflects Changes in Land Use Practices during the Neolithization Process in the Levant

For many, climate change is no longer recognized as the primary cause of cultural changes in the Near East. Instead, human landscape degradation, population growth, socioeconomic adjustments, and conflict have been proposed as the mechanisms that shaped the Neolithic Revolution. However, as Bar-Yosef noted, even if there is chronological correlation between climate changes and cultural developments, what is important is to understand how Neolithic societies dealt with these improving or deteriorating environments. Changes in bifacial stone tools provide a framework for examining some of these interactions by focusing on changing land use practices during the Neolithization process. The results of microwear analysis of 40 bifacial artifacts from early Pre-Pottery Neolithic (EPPNB) levels at Motza in the Judean hills document changes during the PPNA-PPNB transition at the onset of the Levantine Moist Period (ca. 8000 cal B.C.) when conditions for agriculture improved. EPPNB villagers added heavy-duty axes to a toolkit they had used for carpentry and began to clear forests for fields and grazing lands. Sustainable forest management continued for the duration of the PPN until the cumulative effects of tree-felling and overgrazing seem to have led to landscape degradation at end of the Pre-Pottery Neolithic C (PPNC), when a cold, dry climatic anomaly (6600-6000 cal B.C.) may have accelerated the reduction of woodlands. Early PPNB components at sites like Motza, with data from nearly five millennia of Neolithic occupations, show how complex hunter-gatherers and early food producers were able to establish sustainable resource management systems even as climate changed, population increased, and social relations were redefined.     

Beyond the Levant: First Evidence of a Pre-Pottery Neolithic Incursion into the Nefud Desert,Saudi Arabia

Pre-Pottery Neolithic assemblages are best known from the fertile areas of the Mediterranean Levant. The archaeological site of Jebel Qattar 101 (JQ-101), at Jubbah in the southern part of the Nefud Desert of northern Saudi Arabia, contains a large collection of stone tools, adjacent to an Early Holocene palaeolake. The stone tool assemblage contains lithic types, including El-Khiam and Helwan projectile points, which are similar to those recorded in Pre-Pottery Neolithic A and Pre-Pottery Neolithic B assemblages in the Fertile Crescent. Jebel Qattar lies ∼500 kilometres outside the previously identified geographic range of Pre-Pottery Neolithic cultures. Technological analysis of the typologically diagnostic Jebel Qattar 101 projectile points indicates a unique strategy to manufacture the final forms, thereby raising the possibility of either direct migration of Levantine groups or the acculturation of mobile communities in Arabia. The discovery of the Early Holocene site of Jebel Qattar suggests that our view of the geographic distribution and character of Pre-Pottery Neolithic cultures may be in need of revision.     

Ancient DNA Analysis of 8000 B.C. Near Eastern Farmers Supports an Early Neolithic Pioneer Maritime Colonization of Mainland Europe through Cyprus and the Aegean Islands

The genetic impact associated to the Neolithic spread in Europe has been widely debated over the last 20 years. Within this context, ancient DNA studies have provided a more reliable picture by directly analyzing the protagonist populations at different regions in Europe. However, the lack of available data from the original Near Eastern farmers has limited the achieved conclusions, preventing the formulation of continental models of Neolithic expansion. Here we address this issue by presenting mitochondrial DNA data of the original Near-Eastern Neolithic communities with the aim of providing the adequate background for the interpretation of Neolithic genetic data from European samples. Sixty-three skeletons from the Pre Pottery Neolithic B (PPNB) sites of Tell Halula, Tell Ramad and Dja''de El Mughara dating between 8,700–6,600 cal. B.C. were analyzed, and 15 validated mitochondrial DNA profiles were recovered. In order to estimate the demographic contribution of the first farmers to both Central European and Western Mediterranean Neolithic cultures, haplotype and haplogroup diversities in the PPNB sample were compared using phylogeographic and population genetic analyses to available ancient DNA data from human remains belonging to the Linearbandkeramik-Alföldi Vonaldiszes Kerámia and Cardial/Epicardial cultures. We also searched for possible signatures of the original Neolithic expansion over the modern Near Eastern and South European genetic pools, and tried to infer possible routes of expansion by comparing the obtained results to a database of 60 modern populations from both regions. Comparisons performed among the 3 ancient datasets allowed us to identify K and N-derived mitochondrial DNA haplogroups as potential markers of the Neolithic expansion, whose genetic signature would have reached both the Iberian coasts and the Central European plain. Moreover, the observed genetic affinities between the PPNB samples and the modern populations of Cyprus and Crete seem to suggest that the Neolithic was first introduced into Europe through pioneer seafaring colonization.     

Synchronous Environmental and Cultural Change in the Emergence of Agricultural Economies 10,000 Years Ago in the Levant

The commonly held belief that the emergence and establishment of farming communities in the Levant was a smooth socio-economic continuum during the Pre-Pottery Neolithic (ca. 12,000-9,000 cal BP) with only rare minor disruptions is challenged by recently obtained evidence from this region. Using a database of archaeological radiocarbon dates and diagnostic material culture records from a series of key sites in the northern Levant we show that the hitherto apparent long-term continuity interpreted as the origins and consolidation of agricultural systems was not linear and uninterrupted. A major cultural discontinuity is observed in the archaeological record around 10,000 cal BP in synchrony with a Holocene Rapid Climate Change (RCC), a short period of climatic instability recorded in the Northern Hemisphere. This study demonstrates the interconnectedness of the first agricultural economies and the ecosystems they inhabited, and emphasizes the complex nature of human responses to environmental change during the Neolithic period in the Levant. Moreover, it provides a new environmental-cultural scenario that needs to be incorporated in the models reconstructing both the establishment of agricultural economy in southwestern Asia and the impact of environmental changes on human populations.     

Crania with mutilated facial skeletons: A new ritual treatment in an early Pre-Pottery Neolithic B cranial cache at Tell Qarassa North (South Syria)

The removal of crania from burials, their ritual use and their disposal, generally in cranial caches, are the most particular characteristics of the funerary ritual in the transition to the Neolithic in the Near East. Despite the importance of this ritual, detailed studies of cranial caches are rare. This funerary ritual has traditionally been interpreted as a form of ancestor‐veneration. However, this study of the cranial caches found at the site of Tell Qarassa North, South Syria, dated in the second half of the ninth millennium BC, questions this interpretation. The 12 crania, found in two groups arranged in two circles on the floor of a room, belonged to male individuals, apart from one child and one preadolescent. In 10 of the 11 cases, the facial skeletons were deliberately mutilated. In the context of the Pre‐Pottery Neolithic B, when the symbolism of the human face played a vital role in ritual practice, this mutilation of the facial skeleton could be interpreted as an act of hostility. In the absence of indicators of social stratification or signs of violence that might indicate more coercive forms of society, the veneration of ancestors has been explained as a mechanism for social cohesion, which would have been necessary in a context of rapid growth in the population of settlements. However, data on the negative nature of some funerary rites, of punishment or indifference rather than veneration, should make us question an over‐idealized view of the first Neolithic societies.

Has the transition to agriculture reshaped the demographic structure of prehistoric populations? New evidence from the Levant

This paper presents the demographic changes that followed the transition from a hunting-gathering way of life (Natufian) to an agricultural, food-producing economy (Neolithic) in the southern Levant. The study is based on 217 Natufian (10,500-8,300 BC) skeletons and 262 Neolithic (8,300-5,500 BC) skeletons. Age and sex identification were carried out, and life tables were constructed. A five-parameter competing hazard model developed by Siler ([1979] Ecology 60:750-757) was used to smooth life-table data. No indication of increased mortality with the advent of agriculture was noted. On the contrary, both life expectancy at birth (24.6 vs. 25.5 years) and adults' mean age at death (31.2 vs. 32.1 years) increased slightly from the Natufian to the Neolithic period (assuming stationary populations). Yet the transition to agriculture affected males and females differently: mean age at death in the Natufian was higher for adult females compared to adult males, while in the Neolithic, it was the reverse. One interpretation given to the distribution of female ages at death is that with the onset of the Neolithic period, maternal mortality increased as a result of a concomitant increase in fertility. If the adoption of agriculture in the Levant increased the rate of population growth at the beginning of the Neolithic, expectation of life may have increased dramatically.     

Landscape Alteration by Pre-Pottery Neolithic Communities in the Southern Levant – The Kaizer Hilltop Quarry,Israel

This study focuses on Kaizer Hill, a quarry site located in the vicinity of the city of Modiin where remains of a single prehistoric cultural entity assigned to the Pre-Pottery Neolithic A were discovered. A systematic survey revealed that large-scale quarrying activities have left damage markings on the bedrock of the Hilltop and its slopes. We aim to present here our findings from the Hilltop, which are concerned with the human impact on rock surfaces and the lithic artifacts retrieved during the survey. It is evident that the Pre-Pottery Neolithic A inhabitants of the area changed their landscape forever, “stripping” the caliche surface and penetrating it in search of flint bedded in the bedrock.     

Reconsidering the Early Neolithic of Anatolia. Recent recoveries,some excerpts and generalities

In the course of last decades Neolithic research has taken a new pace in Turkey, while projects in the western and the central parts of the of the country have been working mainly on the later stages of the Neolithic era, those in south-eastern Turkey had their focus on the incipient stages of neolithization. Work in the south-eastern parts, highlighted by the results attained at Göbeklitepe has been carrying out large scale excavations at several Pre-Pottery Neolithic sites, most of them having their earliest layers by the very beginning of PPNA, evidence of antecedent stages being highly debatable. Recent recoveries have been greatly elaborating our understanding on the entire span of Neolithic way of living, also displaying the differences among distinct core areas of neolithization. However, more significant is the outcome of new research taking place in the Upper Euphrates-Upper Tigris basins of south-eastern Anatolia, revealing ground breaking results so different from our conventional perceptions that redefining what is implied by the term Neolithic is now stands as an absolute necessity; inevitably some more time is necessary for the newly emerging picture on Neolithic process to sink in. However, some of the recent findings being unexpectedly different is apt to lead to speculative misconceptions, particularly when coupled with deeply rooted biases of research history. In this respect, the paper will present a conspectus on the progressive stages of Neolithic research in Anatolia, touching upon some biases in retrospect. Accordingly, the paper neither intends to cover an exclusive narrative of research history nor to bring the highlights of present research; it is targeted to surface the modalities that patterned past research so as a provide a subtle bases to future prospects.     

Musculoskeletal stress markers in Natufian hunter-gatherers and Neolithic farmers in the Levant: the upper limb

This paper attempts to quantify the changes in activity patterns of early farming populations in the Levant through the musculoskeletal stress markers (MSM) of the upper limb as seen in skeletal remains. The transition to an agricultural way of life resulted in higher loads on the upper limb in Neolithic populations compared to the Natufian hunter-gatherer populations that preceded them. The MSM pattern for males and females indicates a gender-based division of labor both in the Natufian and the Neolithic. It may also suggest that people in the Neolithic period were engaged in different (new) activities and occupations compared to the Natufian.     

Human dental microwear from Ohalo II (22,500-23,500 cal BP), southern Levant

Dietary hardness and abrasiveness are inferred from human dental microwear at Ohalo II, a late Upper Palaeolithic site (22,500-23,500 cal BP) in the southern Levant. Casts of molar grinding facets from two human skeletons were examined with a scanning electron microscope. The size and frequency of microwear was measured, counted, and compared to four prehistoric human groups from successive chronological periods in the same region: pre-pottery Neolithic A, Chalcolithic (this study); Natufian, pre-pottery Neolithic B (Mahoney: Am J Phys Anthropol 130 (2006) 308-319). The Ohalo molars had a high frequency of long narrow scratches, and a few small pits, suggesting a tough abrasive diet that required more shearing rather than compressive force while chewing. These results imply that the diet of the two late Upper Palaeolithic hunter-gatherers did not focus on very hard foods. Aquatic foods with adherent contaminants, as well as grit from plant grinding tools seemed likely causal agents. The size of the pits and scratches on the Ohalo molars were most similar to microwear from the pre-pottery Neolithic A period, though they also compared well to the Chalcolithic period. These results contrasted with the larger pits and scratches from the Natufian hunter-gatherers and pre-pottery Neolithic B farmers, implying that there is no simple increase or decrease in dietary hardness and abrasiveness across the late Upper Palaeolithic to Chalcolithic development in the Southern Levant.     

Paleopathology and the origin of agriculture in the Levant

This study addresses changes in health which were consequential to the Neolithic transition in the southern Levant, judged on the basis of the study of specific and nonspecific stress indicators, trauma, and degenerative joint disease in 200 Natufian (hunter‐gatherer) skeletons (10,500–8300 BC) and 205 Neolithic (agricultural) skeletons (8300–5500 BC) from the southern Levant. The comparison of the health profiles of pre‐Neolithic (Natufian) and Neolithic populations reveals a higher prevalence of lesions indicative of infectious diseases among the Neolithic population, and an overall reduction in the prevalence of skull trauma among males. No change over time was observed in the prevalence of degenerative joint disease. These results indicate that in the southern Levant the Neolithic transition did not simply lead to an overall deterioration in health but rather resulted in a complex health profile which was shaped by 1) an increase exposure to disease agents, 2) changes in diet, 3) population aggregation in larger and denser settlements, 4) changes in activity patterns and the division of labor, and possibly 5) a higher resistant immunological system and response capacity to environmental aggressions (mainly infections).

The pre-Natufian Epipaleolithic: long-term behavioral trends in the Levant

Few cultural developments have taken on as much archeological significance as when people began living in villages and producing their own food. The economic, social, technological, and ideological transformations immediately preceding and following these changes were profound. Early models of culture change associated with pre-agricultural societies of the Levant focused on the sudden, late origin of settled farming villages triggered by climate change. Accompanying this new economic and living situation was durable stone-built architecture; intensified plant and animal use; a flourishing of art and decoration; new mortuary traditions, including marked graves and cemeteries; elaborate ritual and symbolic behavior-a new way of life. This new life style arguably had a slow start, but really took off during the Epipaleolithic period (EP), spanning more than 10,000 years of Levantine prehistory from c. 23,000-11,500 cal BP. The last EP phase, immediately preceding the Neolithic, is by far the best-studied in terms of its cultural and economic contributions to questions on the origins of agriculture.1-4 Recently, archeologists have considered the earlier parts of the EP to be more culturally dynamic and similar to the later phase (Natufian) than was previously thought.3-10 The earlier EP is increasingly seen as demonstrating the behavioral variability and innovations that help us to understand the economic, technological, and social changes associated with complex hunter-gatherers of the Natufian and farmers of the Neolithic. This paper traces the cultural and biological developments of the EP period leading up to the Natufian and considers the long-term trajectory of culture change, social complexity, and village life in the Near East.     

Stable isotopes and dietary adaptations in humans and animals at pre-pottery Neolithic Nevalli Cori, southeast Anatolia

Human and animal bones from the Pre-Pottery Neolithic B site of Nevali Cori (southeast Anatolia) were analyzed with regard to stable carbon and nitrogen isotopes in bone collagen, and stable carbon and oxygen isotopes in bone carbonate. The reconstruction of the vertebrate food web at this site revealed that humans may have faced difficulties with meat procurement, since their stable-isotope ratios reflect a largely herbivorous diet. This is in contrast with the preceding Pre-Pottery Neolithic A contexts and late Neolithic sites in the Fertile Crescent, where humans are located at the top of the food chain. Conceivably, Nevali Cori represents a community in the transition from a hunting and gathering subsistence to an economy with agriculture and animal husbandry, since domesticated einkorn and sheep, pigs, and probably also goats are in evidence at the site. In the second half of the 9th millennium calibrated (cal.) BC, however, the contribution of stock on the hoof to the human diet still seems modest. Animals kept under cultural control obviously had a dietary spectrum different from their free-ranging relatives. We conclude that these animals had been deliberately nourished by their owners, whereby the overall low delta(15)N-signatures in both humans and livestock might result from the consumption of protein-rich pulses.     

The Neolithic of the southern Levant

The Neolithic period of the southern Levant was an era of tremendous change. Over the course of the Neolithic, the gradual transition from foraging to agriculture involved not merely economic innovations, but also profound shifts in population size, social organization, and technology. This represents possibly the earliest, and certainly one of the earliest, instances of the transition to agriculture. The advent of farming altered human demography, health, and diversity; it shaped the spread of the world's dominant cultures, genes, and languages. 1 , 2 It recast humans' relationship with the natural world, increasing modification of the environment. It both enabled and required the development of new social structures as humans learned how to live in increasingly large and densely packed groups. These transformations were not easily achieved. This paper traces the development of the southern Levantine Neolithic through two thousand years of socioeconomic elaboration and expansion; a major social recalibration in the middle Neolithic; and a final millennium‐and‐a‐half of smaller‐scale and materially simpler adaptations.

Intact growth factors are conserved in the extracellular matrix of ancient human bone and teeth: a storehouse for the study of human evolution in health and disease

For the first time we have extracted, solubilized and identified growth factors, such as insulin growth factor II (IGF-II), bone morphogenetic protein-2 (BMP-2), and transforming growth factor-beta (TGF-beta), from archaeological compact human bone and tooth dentin dating from the late pre-ceramic pottery Neolithic (late PPNB) and the early Middle Ages. These factors are typical of special physiological or pathological situations in the metabolism of bone. The extracellular matrix proteins from bone and teeth of individuals from the late PPNB and early Middle Ages were separated by 2-D electrophoresis and more than 300 different protein spots were detected by silver staining. The matrix protein patterns of compact bone and tooth from the same individual (early Middle Ages) are very different and only 16% of the protein spots were detected in both compact bone and tooth dentin.     

From foraging to farming in the southern Levant: the development of Epipalaeolithic and Pre-pottery Neolithic plant management strategies

This paper reviews the archaeobotanical record of the transition from foraging to farming in the southern Levant. The concise presentation of the published botanical evidence follows a critical assessment of: (a) the nature of Epipalaeolithic plant management strategies, (b) the place of the southern Levant in the polycentric development of Near Eastern plant cultivation and domestication, and (c) region-specific pathways for the emergence of domesticated crop “packages”. Some inferences are drawn and suggestions are made concerning the potential contribution of archaeobotanical research to questions of broader archaeological significance about socio-economic change in the southern Levant during the Pre-pottery Neolithic.     

Tooth wear and dental pathology at the advent of agriculture: new evidence from the Levant

Differences in patterns of diet and subsistence through the analysis of dental pathology and tooth wear were studied in skeletal populations of Natufian hunter-gatherers (10,500-8300 BC) and Neolithic populations (8300-5500 BC, noncalibrated) from the southern Levant. 1,160 Natufians and 804 Neolithic teeth were examined for rate of attrition, caries, antemortem tooth loss, calculus, periapical lesions, and periodontal processes. While the Natufian people manifest a higher rate of dental attrition and periodontal disease (36.4% vs. 19%), Neolithic people show a higher rate of calculus. Both populations manifested low and similar rates of caries (6.4% in the Natufian vs. 6.7% in the Neolithic), periapical lesions (not over 1.5%), and antemortem tooth loss (3.7% vs. 4.5%, respectively). Molar wear pattern in the Neolithic is different than in the Natufian. The current study shows that the dental picture obtained from the two populations is multifactorial in nature, and not exclusively of dietary origin, i.e., the higher rate and unique pattern of attrition seen in the Natufian could result from a greater consumption of fibrous plants, the use of pestles and mortars (which introduce large quantities of stone-dust to the food), and/or the use of teeth as a "third hand." The two major conclusions of this study are: 1) The transition from hunting and gathering to a food-producing economy in the Levant did not promote changes in dental health, as previously believed. This generally indicates that the Natufians and Neolithic people of the Levant may have differed in their ecosystem management (i.e., gathering vs. growing grains), but not in the type of food consumed. 2) Changes in food-preparation techniques and nondietary usage of the teeth explain much of the variation in tooth condition in populations before and after the agricultural revolution.     

Insights into the Social Structure of the PPNB Site of Kfar HaHoresh,Israel, Based on Dental Remains

One of the central questions of the transition from mobile hunter-gatherers to sedentary farming communities concerns the establishment of new social structures and group identities. Along with other important factors, such as territory, ideology or economy, biological relationships might have played a decisive role in defining social groups. We therefore systematically analyzed teeth and jaw remains from nine sites in the Near East dating from the Natufian to the Late PPNB as primary proxy data for the reconstruction of familial relationships. This paper presents the results of morphological analyses on the teeth of the individuals from Kfar HaHoresh, one of the investigated Pre-Pottery Neolithic B sites. Kfar HaHoresh is located in the Nazareth hills of Galilee (32°42''20'''' N 35°16''28'''' E), Israel. Different statistical methods were applied to our data of epigenetic traits with the aim of determining biological relationships within the community, whereby the data of the eight other sites were used as cross-references. Our comparison of the traits of all individuals from Kfar HaHoresh indicates a rather heterogeneous community, but clearly shows one cluster belonging to a quite homogenous group, suggesting close biological relations between females and sub-adults. Interestingly, none of the male individuals belongs to this cluster, although their number outweighs that of the female individuals. This might suggest matrilocal residence patterns. However, due to the incomplete preservation of the teeth along with several other uncertainties, our conclusion must be seen as preliminary. A cross-examination of the results on skeletons excavated after our investigation should also be taken into consideration.
