The purpose of this article is to present new oral health data from Neolithic An Son, southern Vietnam, in the context of (1) a reassessment of published data on other Neolithic, Bronze, and Iron Age Southeast Asian dental series, and (2) predictions of the Neolithic Demographic Transition (NDT). To this end, frequencies for three oral conditions (caries, antemortem tooth loss, and alveolar lesions) were investigated for seven Southeast Asian adult dental series from Thailand and Vietnam with respect to time period, age‐at‐death and sex. A clear pattern of elevated rates for oral disease in the Neolithic followed by a marked improvement in oral health during the Bronze and Iron Ages was observed. Moreover, rates of caries and antemortem tooth loss for females were almost without exception higher than that for males in all samples. The consensus view among Southeast Asian bioarchaeologists that oral health did not decline with the adoption/intensification of agriculture in Southeast Asia, can no longer be supported. In light of evidence for (1) the low cariogenicity of rice; (2) the physiological predisposition of females (particularly when pregnant) to poorer oral health; and (3) health predictions of the NDT model with respect to elevated levels of fertility, the most plausible chief explanation for the observed patterns in oral health in Southeast Asia is increased levels of fertility during the Neolithic, followed by a decline in fertility during the subsequent Bronze and Iron Ages.

Humeral morphology has been shown to reflect, in part, habitual manipulative behaviors in humans. Among Central European agricultural populations, long-term social change, increasing task specialization, and technological innovation all had the potential to impact patterns of habitual activity and upper limb asymmetry. However, systematic temporal change in the skeletal morphology of agricultural populations in this region has not been well-characterized. This study investigates diachronic patterns in humeral biomechanical properties and lengths among 174 adult Central European agriculturalists through the first ∼5400 years of farming in the region. Greater asymmetry in biomechanical properties was expected to accompany the introduction of metallurgy, particularly in males, while upper limb loading patterns were expected to be more similar between the Bronze and Iron Ages. Results revealed a divergence in the lateralization of upper limb biomechanical properties by sex between the Early/Middle Neolithic and Early/Middle Bronze Age. Neolithic females had significantly more variable properties than males in both humeri, while Bronze Age female properties became homogeneous and very symmetrical relative to the right-biased lateralization of contemporaneous males. The Bronze Age to Iron Age transition was associated with morphological change among females, with a significant increase in right-biased asymmetry and a concomitant reduction in sexual dimorphism. Relative to biomechanical properties, humeral length variation and asymmetry were low though some significant sexual dimorphism and temporal change was found. It was among females that the lateralization of humeral biomechanical properties, and variation within them, changed most profoundly through time. This suggests that the introduction of the ard and plow, metallurgical innovation, task specialization, and socioeconomic change through ∼5400 years of agriculture impacted upper limb loading in Central European women to a greater extent than men. 相似文献

This paper reports on seeds of Lallemantia (Lamiaceae) found at Bronze Age sites in northern Greece. At several of these sites, the seeds were found in significant
concentrations in storage contexts, suggesting that they were deliberately stored for use by the inhabitants. Oil from the
seeds of Lallemantia can be used for a variety of purposes, including food, lighting and medicine. This genus is not native to Greece, the nearest
modern occurrences of Lallemantia species being in Anatolia from where they extend further east as far as Iran, or beyond. To date, it has not been found in
Neolithic deposits in Greece, despite significant archaeobotanical research, especially in northern Greece. This suggests
that it first appeared in Greece in the early Bronze Age, and indicates long distance contacts with communities to the east
or north at this time. It is difficult to establish whether its continued use indicates that seeds of this genus were repeatedly
brought into Greece throughout the Bronze Age or that the genus was introduced in the early Bronze Age and then locally cultivated.
The presence of seeds, however, may suggest that Lallemantia was locally cultivated, as it would have been possible to import it in the form of oil. The appearance of a new import or
introduction at this time adds to the evidence for external contact during the Bronze Age. Lallemantia may have been part of a group of oil producing taxa which became significant during the Bronze Age in northern Greece paralleling
the increased importance of the olive in southern Greece. 相似文献

Two almost complete and articulated skeletons of a small-sized 15-year-old shorthorn ox and of a 3-4-year-old dog were found associated to Iron Age human burials at Madonna del Piano, in Sesto Fiorentino, near Florence. The two skeletons were ritually buried. The find adds to another case of cattle burial also found in the area, and therefore attests to a penetration and persistence of late Neolithic and Bronze Age northern and eastern European practices in Italy. The specimens provide important evidence on the habits and believes of Iron Age circum-Mediterranean human populations. The ox reveals that castration was accomplished late in the animal’s growth, but also that cattle were used for heavy work, though being worshiped animals. 相似文献

The house mouse progression in Eurasia: a palaeontological and archaeozoological approach 总被引:2,自引:0,他引:2

A palaeontological and archaeozoological survey has allowed us to establish the different steps in the colonization of western Eurasia and northern Africa by the house mouse Mus musculus . After successive immigration waves of the genus Mus into this zone from the late Pliocene to the upper Pleistocene, the house mouse appeared and remained confined to the easternmost Mediterranean Basin at the uppermost Pleistocene. The first progression of this species into the Mediterranean Basin occurred in the Middle East from the Epipaleolithic to the Neolithic. Subsequently, this species was found in the western Mediterranean Basin during the Bronze Age and in north-west Europe during the Iron Age. In comparison to this latter zone, north central Europe was colonized relatively early, from the Neolithic to the Bronze Age which may, in fact, not only correspond to a much earlier invasion of Europe by M. musculus musculus but also suggest that the distribution of this subspecies extended much further west than it does nowadays, at a time when M. musculus domesticus was restricted to the Mediterranean zone. This archaeological survey is in agreement with genetic data which provide indications as to the speed, steps and pathways of progression of house mouse populations in western Eurasia. 相似文献

Development of the cultural landscape in a village situated by the inner fjords of western Norway is investigated by pollen analysis and quantitative reconstruction methods. Pollen samples from lake sediments and a soil profile were analysed and represent different spatial scales. The Landscape Reconstruction Algorithm (LRA) is applied to a large and a small lake to convert pollen percentages from the small lake into estimated local vegetation cover in selected time periods starting from 2800 cal bc (Middle Neolithic A). This reconstruction shows that estimated forest cover has fluctuated through time, and changes in openness related to human impact are distinct from the Early Bronze Age (1800–1200 cal bc). Pollen analyses from the soil profile indicate forest clearances from the Late Neolithic (2300–1800 cal bc). Gradual intensification of farming is recognized in both pollen diagrams throughout the Bronze and Iron Ages with increasing openness and spatial differentiation in land-use practices. Presence of pollen of cereals and flax record the cultivation of these plants from the Iron Age, and intensification of land-use may have caused erosion and re-sedimentation in the lake in medieval times. To identify a possible landscape in the past, HUMPOL software has been used with the Late Neolithic as a case study. The LRA-based estimates of forest cover are supported by the HUMPOL simulations, but several solutions to the Late Neolithic landscape pattern exist. The results clearly demonstrate how implementation of LRA and HUMPOL improve the understanding of cultural landscape development. 相似文献

我国新疆地区自古以来即是东西方文明相互交融的摇篮,以往的考古学、体质人类学研究表明,该区域内不同文化之间的互通有无早在我国青铜-早期铁器时代便已经发生。关于这种交流与融合产生的原因,目前学术界仍未有定论。新疆于田流水墓地(2950±50 BP)是由中国社会科学院考古研究所于2003-2005年主持发掘的青铜时代墓葬群,该墓地共发掘墓葬65座,被视为是昆仑山北麓发现的最早人类文化遗存。本文从采集自流水墓地108例人骨标本的19项牙齿非测量性状研究入手,将其与欧亚大陆范围内的古今人群进行比较研究,并进行史密斯生物学距离的计算以及主成分分析。结果表明:生活在新疆流水地区的古代人类与南西伯利亚地区、日本绳纹、阿富汗/巴基斯坦、中国姜家梁地区人群之间在牙齿非测量性状方面存在某种程度上的相似性,这或许可以说明至少在3000年前,我国新疆西南部地区可能已经存在了东西方的人群迁徙。 相似文献

The lake sediment record was used to reconstruct past vegetation dynamics and human impacts from the middle Neolithic (6500 cal. b.p.) to the Middle Ages (1500 cal. b.p.) around Lac d’Antre in the southern Jura mountains of France. This lake was surrounded by the Gallo-Roman sanctuary of Villards d’Héria, which has been widely investigated by archaeologists and enables a comparison between palaeoenvironmental proxies and archaeological data. Pollen and microscopic charcoal analyses were conducted on a 500 cm sediment core with eleven radiocarbon dates providing the chronological control. In a mixed oak woodland context, the successive development of Taxus, Fagus and Abies were mainly caused by climatic variations during the Neolithic, in which there was weak human impact. The first significant signs of human activity were detected during the Bronze Age from 3900 cal. b.p., followed by an increase of human pressure and woodland clearances during the Iron Age, from 2700 cal. b.p. The occupation of the Gallo-Roman sanctuary was continuous with the Iron Age occupation. All the analysed palaeoenvironmental data indicate that the strongest human impact occurred during the Gallo-Roman period, which matches the occupation of Villards d’Héria previously dated by archaeologists from 2000 to 1700 cal. b.p., 1st to 3rd century a.d. Moreover, there appears to have been a new period of human settlement close to the lake at the beginning of the Middle Ages. The low charcoal accumulation rate (CHAR) recorded during the Bronze and Iron Ages suggests that fire was not the main agent used to clear the dense woods to create new cultivated fields and pastures. High CHAR values recorded during the Roman period may represent fire use for domestic and agro-pastoral activities. 相似文献

Although Uzbekistan and Central Asia are known for the well-studied Bronze Age civilization of the Bactria–Margiana Archaeological Complex (BMAC), the lesser-known Iron Age was also a dynamic period that resulted in increased interaction and admixture among different cultures from this region. To broaden our understanding of events that impacted the demography and population structure of this region, we generated 27 genome-wide single-nucleotide polymorphism capture data sets of Late Iron Age individuals around the Historical Kushan time period (∼2100–1500 BP) from three sites in South Uzbekistan. Overall, Bronze Age ancestry persists into the Iron Age in Uzbekistan, with no major replacements of populations with Steppe-related ancestry. However, these individuals suggest diverse ancestries related to Iranian farmers, Anatolian farmers, and Steppe herders, with a small amount of West European Hunter Gatherer, East Asian, and South Asian Hunter Gatherer ancestry as well. Genetic affinity toward the Late Bronze Age Steppe herders and a higher Steppe-related ancestry than that found in BMAC populations suggest an increased mobility and interaction of individuals from the Northern Steppe in a Southward direction. In addition, a decrease of Iranian and an increase of Anatolian farmer-like ancestry in Uzbekistan Iron Age individuals were observed compared with the BMAC populations from Uzbekistan. Thus, despite continuity from the Bronze Age, increased admixture played a major role in the shift from the Bronze to the Iron Age in southern Uzbekistan. This mixed ancestry is also observed in other parts of the Steppe and Central Asia, suggesting more widespread admixture among local populations. 相似文献

嫩江流域是中国东北地区古代先民的重要栖息地之一。自新石器时代开始这里的先民一直以渔猎经济为主要生活方式,直到新石器时代晚期至早期青铜时代才开始兼营畜牧业和少量的种植业。嫩江流域青铜时代的生业模式的转变是否伴随着外来人群的融合与替代一直是考古研究的热点。为了探讨嫩江流域新石器时代与青铜铁器时代人群的构成是否改变,我们对嫩江流域新石器时代至青铜铁器时代的24个个体进行了线粒体全基因组分析。分析结果表明:嫩江流域青铜铁器时代人群与新石器时代人群具有一定遗传连续性的同时,晚期人群与西辽河地区古代人群有着更近的遗传联系,表明西辽河地区古代居民对嫩江流域青铜铁器时代人群具有部分遗传贡献。结合考古学文化、古气候学数据以及语言学证据,我们推测距今4000-3000年间,西辽河地区古代居民曾迁入到嫩江流域,并留下遗传印记。 相似文献

Sheep were among the first domesticated animals to appear in Estonia in the late Neolithic and became one of the most widespread livestock species in the region from the Late Bronze Age onwards. However, the origin and historical expansion of local sheep populations in Estonia remain poorly understood. Here, we analysed fragments of the hypervariable D‐loop of mitochondrial DNA (mtDNA; 213 bp) and the Y‐chromosome SRY gene (130 bp) extracted from 31 archaeological sheep bones dated from approximately 800 BC to 1700 AD. The ancient DNA data of sheep from Estonia were compared with ancient sheep from Finland as well as a set of contemporary sheep breeds from across Eurasia in order to place them in a wider phylogeographical context. The analysis shows that: (i) 24 successfully amplified and analysed mtDNA sequences of ancient sheep cluster into two haplogroups, A and B, of which B is predominant; (ii) four of the ancient mtDNA haplotypes are novel; (iii) higher mtDNA haplotype diversity occurred during the Middle Ages as compared to other periods, a fact concordant with the historical context of expanding international trade during the Middle Ages; (iv) the proportion of rarer haplotypes declined during the expansion of sheep from the Near Eastern domestication centre to the northern European region; (v) three male samples showed the presence of the characteristic northern European haplotype, SNP G‐oY1 of the Y‐chromosome, and represent the earliest occurrence of this haplotype. Our results provide the first insight into the genetic diversity and phylogeographical background of ancient sheep in Estonia and provide basis for further studies on the temporal fluctuations of ancient sheep populations. 相似文献

Multiple geographical regions have been proposed for the domestication of Equus caballus . It has been suggested, based on zooarchaeological and genetic analyses that wild horses from the Iberian Peninsula were involved in the process, and the overrepresentation of mitochondrial D1 cluster in modern Iberian horses supports this suggestion. To test this hypothesis, we analysed mitochondrial DNA from 22 ancient Iberian horse remains belonging to the Neolithic, the Bronze Age and the Middle Ages, against previously published sequences. Only the medieval Iberian sequence appeared in the D1 group. Neolithic and Bronze Age sequences grouped in other clusters, one of which (Lusitano group C) is exclusively represented by modern horses of Iberian origin. Moreover, Bronze Age Iberian sequences displayed the lowest nucleotide diversity values when compared with modern horses, ancient wild horses and other ancient domesticates using nonparametric bootstrapping analyses. We conclude that the excessive clustering of Bronze Age horses in the Lusitano group C, the observed nucleotide diversity and the local continuity from wild Neolithic Iberian to modern Iberian horses, could be explained by the use of local wild mares during an early Iberian domestication or restocking event, whereas the D1 group probably was introduced into Iberia in later historical times. 相似文献

Questions: (i) Can sampling of soil wood charcoals at high spatial resolution produce new evidence concerning the presence of chalk grassland before or during the Neolithic, Bronze and Iron Ages? (ii) Are there correlations between vegetation history and archeological data during these periods at this particular site? Location: The chalk hillsides of Saint‐Adrien in the lower Seine Valley, Upper Normandy, northwest France. Methods: The study was carried out at a high spatial resolution in chalk grassland using soil wood charcoal analysis, in which charcoals found in the soil were identified and dated in an area of several hundred square meters. Results: Late‐successional woody species (Fagus sylvatica, Quercus sp.) were still present in the study site in an area inconsistent with the existence of large chalk grassland herbaceous plant communities (several hectares) in the Neolithic (6500–3800 BP) and Bronze Age (3800–2700 BP). Conclusions: The presence of late‐successional woody species on the studied hillside suggests that fires in the Neolithic were linked to forest clearance for pastoral activities, as already demonstrated for similar ecosystems in eastern France and Germany. Nevertheless, our methodology clearly demonstrates that palaecological studies need to take into account the spatial organisation of plant communities as a complementary element to validate their potential existence in former times. 相似文献

Recent research from the site of Pella in Jordan examines the process and timing of olive cultivation. The frequent presence of olive remains from the Pottery Neolithic, beginning in the Yarmoukian, suggests that exploitation of the olive dates from as early as c. 6200 cal bce, with evidence of oil pressing from at least c. 5200 cal bce. Morphometric data, spanning the Late Neolithic to the Middle Iron Age II, using the measurement of olive endocarp length and width, demonstrates a reduction in the size variation of olive endocarps through time, in addition to an increase in their length, likely the result of selection pressure on trees. At Pella, this change occurs sometime after the Chalcolithic and before the Late Bronze Age, probably post-dating the earliest phases of the Early Bronze Age. Domestication is thus later than Teleilat Ghassul (Jordan), which has the earliest morphological evidence for olive domestication, and suggests that olive domestication was a regionally and temporally diverse process. 相似文献

The transition from the Neolithic to the Early Bronze Age in Central Europe has often been considered as a supra-regional uniform process, which led to the growing mastery of the new bronze technology. Since the 1920s, archaeologists have divided the Early Bronze Age into two chronological phases (Bronze A1 and A2), which were also seen as stages of technical progress. On the basis of the early radiocarbon dates from the cemetery of Singen, southern Germany, the beginning of the Early Bronze Age in Central Europe was originally dated around 2300/2200 BC and the transition to more complex casting techniques (i.e., Bronze A2) around 2000 BC. On the basis of 140 newly radiocarbon dated human remains from Final Neolithic, Early and Middle Bronze Age cemeteries south of Augsburg (Bavaria) and a re-dating of ten graves from the cemetery of Singen, we propose a significantly different dating range, which forces us to re-think the traditional relative and absolute chronologies as well as the narrative of technical development. We are now able to date the beginning of the Early Bronze Age to around 2150 BC and its end to around 1700 BC. Moreover, there is no transition between Bronze (Bz) A1 and Bronze (Bz) A2, but a complete overlap between the type objects of the two phases from 1900–1700 BC. We thus present a revised chronology of the assumed diagnostic type objects of the Early Bronze Age and recommend a radiocarbon-based view on the development of the material culture. Finally, we propose that the traditional phases Bz A1 and Bz A2 do not represent a chronological sequence, but regionally different social phenomena connected to the willingness of local actors to appropriate the new bronze technology. 相似文献

After the beginning of metal processing at the transition from the Neolithic to the Bronze Age, further knowledge of ore mining
and smelting had spread from the Near East to central Europe. In the copper ore deposits of Schwaz, in the central part of
the Alps, the oldest traces of copper mining derive from the early to middle Bronze Ages. Investigation of a middle to late
Bronze Age (1410–920 cal B.C.) slag-washing site in the area revealed a carbonised seed of Nigella damascena (Ranunculaceae) (love-in-a-mist) together with individual other food plants. The plant remains had become incorporated into
the slag sediments by chance and had been preserved in an excellent state due to toxic copper salts contained in the soil.
Nigella damascena, like N. sativa (black cumin), is traditionally used as a condiment and healing herb in southern Europe and the Near East, but has never
grown in the wild in central Europe. Until now, there has been no evidence of prehistoric large-scale cultivation of N. damascena in central Europe. This leads to two possible conclusions: the find may either originate from an exchange of goods with the
cultures in the Mediterranean during the Bronze Age, or indicate an introduction of the plant by an immigrant population from
that area. Implicating the latter alternative together with the archaeological context of the ore processing site suggests
that Nigella damascena had been introduced to the Alps by foreign miners in the course of ore exploitation during the middle to late Bronze Age. 相似文献

The population history of Southeast (SE) China remains poorly understood due to the sparse sampling of present-day populations and limited modeling with ancient genomic data. We report genome-wide genotyping data from 207 present-day Han Chinese and Hmong-Mien (HM)-speaking She people from Fujian and Taiwan Island, SE China. We coanalyzed 66 Early Neolithic to Iron Age ancient Fujian and Taiwan Island individuals obtained from previously published works to explore the genetic continuity and admixture based on patterns of genetic variations of the high-resolution time transect. We found the genetic differentiation between northern and southern East Asians was defined by a north–south East Asian genetic cline and our studied southern East Asians were clustered in the southern end of this cline. The southeastern coastal modern East Asians are genetically similar to other southern indigenous groups as well as geographically close to Neolithic-to-Iron Age populations, but they also shared excess alleles with post-Neolithic Yellow River ancients, which suggested a southward gene flow on the modern southern coastal gene pool. In addition, we identified one new HM genetic cline in East Asia with the coastal Fujian HM-speaking She localizing at the intersection between HM and Han clines. She people show stronger genetic affinity with southern East Asian indigenous populations, with the main ancestry deriving from groups related to southeastern ancient indigenous rice farmers. The southeastern Han Chinese could be modeled with the primary ancestry deriving from the group related to the Yellow River Basin millet farmers and the remaining from groups related to rice farmers, which was consistent with the northern China origin of modern southeastern Han Chinese and in line with the historically and archaeologically attested southward migrations of Han people and their ancestors. Our estimated north–south admixture time ranges based on the decay of the linkage disequilibrium spanned from the Bronze Age to historic periods, suggesting the recent large-scale population migrations and subsequent admixture participated in the formation of modern Han in SE Asia. 相似文献
