We report palaeogenetic analysis of domesticated dog (Canis familiaris) remains excavated from three archaeological sites from southeast France and dating from Middle Neolithic. Ancient DNA analysis was attempted on teeth and bone samples taken from 11 dogs. Three 266-base-pair fragments of the mitochondrial genome Hypervariable Region I (HVR-I) could be retrieved and revealed two haplotypes belonging to HVR-I lineage C. These three sequences were compared to the sequences of Swedish and Italian Neolithic dogs and permitted to confirm that clade C was largely represented all over Western Europe during this period. One haplotype defined in Neolithic French dog was observed for the first time in Canis mtDNA, underlining the loss of mitochondrial diversity in Europe since the Neolithic. Finally, these results point out mitochondrial lineage replacement in Europe, since lineage C represents only 5% of extant European dogs. Altogether, these results support the proposition that palaeogenetic studies are essential for the reconstruction of the past demographic history and the domestication process of dogs. 相似文献

The combined application of remote sensing techniques is often the most effective way for deepening the knowledge on very large archaeological sites (several hectares). In particular, geophysics and aerial photography could yield very detailed information on buried structures not only outlining their location but also, in many cases, defining their planimetry. Moreover, the accurate geocoding of different data sets and the use of GIS for their integration allow to extract the most comprehensive information from a combined study. 相似文献

In traditional Bantu-speaking societies in southern Africa, drought is caused by breaches in rules of pollution. At times of severe drought (3–5 consecutive seasons), rainmakers ascend special hills to perform special rituals. The archaeological signature of this unique activity forms a cultural proxy for drought. New research shows that burnt daga structures also correlate with high δ15N values for small stock. Burnt structures thus form a new component to the proxy. According to the ethnography, farmers implicated in the cause burnt their grain bins, and sometimes houses, as a ritual of cleansing. The dating of these structures provides a revised climatic sequence for the plateau portion of the summer rainfall region. Among other new results, there was a drought at the end of the Mapungubwe period (ca. AD 1300). At about AD 1650, droughts associated with the arrival of maize caused people to stop growing it as food for a while. 相似文献

The lithic assemblage from the Middle Palaeolithic site of Payre (Rhone Valley, France) contains a large number of convergent tools and pointed tools of various shapes, sizes and retouch types. These were excavated from several archaeological units, dating from marine isotopic stages 8–5, which also yielded human skeletal remains. Consideration of this large tool kit has led to an improved analysis of Middle Palaeolithic tools with two retouched convergent edges. The 350 tools were not described within the classical typological framework, but, rather, from a lithic technological perspective in relation to a discoid debitage. In addition, an initial macroscopic use-wear analysis aided in establishing whether they were used according to their technical and/or morphological features. The Middle Palaeolithic convergent tools from Payre are shown to be quite diversified, and the question of the significance of the retouch and the definition of the various types is addressed. Initial functional results indicate that a clear relationship between shape and function cannot be easily established, and that these tools were used as hand tools. This study contributes to the debate on the use of stone tip spears in the Early European Middle Palaeolithic. 相似文献

ABSTRACTFrom 1945, consistent with its broader South Pacific ambitions, Australia sought to strengthen its economic position in New Caledonia. The leaders of the European-descended ‘Caledonian’ community wanted economic autonomy for the territory and improved trade with Australia. Yet the opportunity proved illusory. France remained committed to imperial preference and economic dominance. Its revival was underwritten by Marshall Plan aid, including in New Caledonia. Australia failed to provide enough of the coal that appeared to offer economic influence. In the 1950s the Melanesians gained the vote, and the Caledonians lost political power. Conservative governments in Australia showed less interest than their Labor predecessors. Australia would have welcomed an economically autonomous New Caledonia with close Australian links, but this idea clashed with France's centralist and unitary traditions. In the tension between New Caledonia's geography and its history, France had ensured that history won. 相似文献

The following article corrects the mistaken assumption held by a number of historians that during the reign of Charles VI of France it was necessary for the Parlement de Paris to publish and register all important royal ordinances before they could be executed. Individual cases are discussed to show the nature of the prerogatives of the Parlement and the methods used for the ratification and registration of royal acts. 相似文献

大同南郊北魏墓群研究 总被引:1,自引:0,他引:1
通过对时代特征强、演变快的陶器进行分析,可将大同南郊北魏墓群进行重新分组,167座墓葬共划分为五组,其中包含两个数量不多的过渡特征组。遗迹现象表明,第三组时是大同南郊墓地形成史上的巨变时期,此时北魏经历了太和改革和迁都洛阳,第三组墓葬所表现的维持和破坏并存的状况,当是当时现实社会的真实写照。 相似文献
