延边地区为中国朝鲜族的最大聚居区,朝鲜族先民从朝鲜半岛移居该地的同时便建立了一些早期社会团体。这些社会团体标榜代表朝鲜族垦民利益,争取参与和协助当地政府有关朝鲜族垦民事务。然而,由于社会团体组织者的阶级成分复杂,政治立场模糊,不仅未能真正代表广大朝鲜族垦民的切身利益,而且团体之间为争夺垦民和扩大势力勾心斗角,结果两败俱伤,很快退出历史舞台,这表明了朝鲜族早期社会团体的不成熟性和团体组织者的阶级局限性。 相似文献

Traditional syntheses of the archaeology of the late Pleistocene period in South America have focused primarily on the peopling of the continent by North American cultural groups and on identifying associations among regional sites. This focus has tended to ignore the widespread culture diversity of the period and the possible effects of different paleolandscapes on human migration and colonization, such as the presence of unglaciated tropical and temperate environments in the northern lowlands, the gateway to the interior. The earliest known cultural assemblages are characterized by various unifacial and bifacial lithic industries that may represent regional processes reminiscent of an Archaic lifeway. The major archaeological sites and associated artifact assemblages are examined in terms of regional and continental patterns of environmental and cultural change. Results suggest that the Pleistocene archaeological record of South America must be explained in its own terms and that the events and processes producing this record either occurred earlier than previously thought or are very different from those in North America. 相似文献

Current interest in the origins of anatomically modernHomo sapiens has focused attention on early modern human remains and related archaeological materials associated with the southern African Middle Stone Age. While the anatomically modern status and a Last Interglacial or later age for the human fossils enjoy general support, issues related to the definition of the Middle Stone Age, its dating, and the interpretation of human behavior lack consensus. Available evidence suggests that the anatomically modern human skeleton appeared well before many aspects of the subsistence and symbolic behavior that characterize recent foragers and that Middle Stone Age technology persisted longer in southern Africa than its northern hemisphere counterpart. 相似文献

The domesticated Red Jungle-fowl G. gallus is believed to have been dispersed by man from India during the Holocene. The distal end of a radius from the Ipswichian Interglacial deposits at Crayford, Kent, was indistinguishable from that of the wild form of Red Jungle-folw. A coracoid from the early Middle Pleistocene of N Norfolk was also very similar to that species but showed differences comparable with those found between different species of Gallus. At least one species referable to Gallus is known from the Pliocene of South-eastern Europe. Extrapolating from zoogeographical speciation patterns it would be possible for a Gallus species to have evolved through Pleistocene speciation in the European region. The species might have become extinct during a glaciation or have been exterminated by early man. A new species Gallus europaeus is described with the coracoid as a holotype, and the radius from Kent is tentatively referred to it. 相似文献

Toward the end of the Pleistocene, North America lost some 35 genera of mammals. It has long been assumed that all or virtually all of the extinctions occurred between 12,000 and 10,000 years ago, but detailed analyses of the radiocarbon chronology provide little support for this assumption, which seems to have been widely accepted because of the kinds of explanations felt most likely to account for the extinctions in the first place. Approaches that attribute the losses to human predation depend almost entirely on the assumed synchroneity between the extinctions and the onset of large mammal hunting by North American peoples. The fact that only two of the extinct genera have been found in a convincing kill context presents an overwhelming problem for this approach. Climatic models, on the other hand, are becoming increasingly precise and account for a wide variety of apparently synchronous biogeographic events. While a role for human activities in the extinction of some taxa is fully possible, there can be little doubt that the underlying cause of the extinctions lies in massive climatic change. 相似文献

Imported Mediterranean pottery recovered from 5th–7th century settlement sites along the south Wales coast indicates that trade and contact between Wales and Byzantium continued following the collapse of the Roman Empire in the early-5th century. It is hypothesised that people as well as pottery continued to travel to Wales from Byzantium, some of whom subsequently settled amongst the local communities. Strontium and oxygen isotope analysis was undertaken on human remains (n = 33 individuals) from four early medieval cemeteries from south Wales. The study identified individuals who may not have been local to the British Isles, thus demonstrating that the isotopic analysis of human remains from Wales can further our understanding of migration to Britain during the early medieval period. 相似文献

A trial excavation was carried out on the near-submerged crannog at Ederline Boathouse, Loch Awe, in July 2004. A trench measuring 3 × 5 m was opened on the northern side, in c .3 m of water. Around 1 m of organic deposits was encountered, along with structural timbers and animal bones. Despite a previous 4th century BC radiocarbon determination from a structural timber, a sherd of E ware from a sealed context gives an Early Historic date for the deposits excavated in 2004. The results from this first intrusive investigation of a Loch Awe crannog demonstrate that these sites are complex and long-lived.
