The desert and arid steppes of Mongolia and northern China were geographically central to the spread of pastoralism and the rise of pastoralist states, but research on the organizational strategies of pre-pastoralist hunter-gatherers and the spread of herding has been extremely limited. Until recently, catalogues of sites collected by Westerners in the 1920s and 1930s comprised the body of English-language publications on Gobi Desert prehistory. This article introduces a wealth of new site-specific and interpretive data, drawing on English-language sources as well as Russian- and Mongolian-language publications to create a synthesis for the prehistory of the Gobi Desert from the end of the Last Glacial Maximum to the adoption of herding. Special emphasis is placed on the relationship between a major shift in desert ecosystems, comparable to the ‘greening of the Sahara’, the establishment of an oasis-based broad-spectrum foraging strategy, and progressive desertification and deforestation after 2000 BC. We conclude that an oasis-based adaptation was contemporaneous with the expansion of forests and wetlands and persisted throughout the early stages of herding. A major decline in these economies occurs after 1000 BC, in conjunction with continuing trends towards heightened aridity and major societal changes across Northeast Asia. The persistent co-existence of Bronze Age burials and microblade-based habitation sites around oases, as well as similarities in material culture, suggest that these groups overlapped geographically or were the same entity.  相似文献

The development of large agglomerations is one of the most important phenomena in later Eurasian prehistory. In west-central temperate Europe, the origins of urbanism have long been associated with the oppida of the second to first centuries BC. However, large-scale excavations and surveys carried out over the last two decades have fundamentally modified the traditional picture of early centralization processes. New results indicate that the first urban centres north of the Alps developed over time between the end of the seventh and the fifth century BC in an area stretching from Bohemia to southern Germany and Central France. Sites such as the Heuneburg, Závist, Mont Lassois and Bourges produce evidence of a process of differentiation and hierarchization in the pattern of settlement that was concurrently an expression of, and a catalyst for, increasing social inequality. Although contacts with the Mediterranean world would certainly have played a role in such processes, endogenous factors were primarily responsible for the development of these early Central European agglomerations. This paper summarizes recent fieldwork results, showing the heterogeneity and diversity of Early Iron Age central places and outlining their diachronic development. The fragility and ephemeral character of these centres of power and their territories is highlighted. Their demise was followed by a period of decentralization that constitutes a prime example of the non-linear character of history.  相似文献

Although debate continues, there is agreement that dogs (Canis lupus familiaris) were first domesticated in Eurasia, spreading from there to other parts of the world. However, while that expansion already extended as far as Europe, China, and North America by the early Holocene, dogs spread into (and south of) the tropics only much later. In South America, for example, the earliest well-attested instances of their presence do not reach back much beyond 3000 cal. BC, and dogs were still absent from large parts of the continent—Amazonia, the Gran Chaco, and much of the Southern Cone—at European contact. Previous explanations for these patterns have focused on cultural choice, the unsuitability of dogs for hunting certain kinds of tropical forest prey, and otherwise unspecified environmental hazards, while acknowledging that Neotropical lowland forests witness high rates of canine mortality. Building on previous work in sub-Saharan Africa (Mitchell in Archaeol Res Afr 50:92–135, 2015), and noting that the dog’s closest relatives, the grey wolf (C. lupus) and the coyote (C. latrans), were likewise absent from South and most of Central America in pre-Columbian times, this paper explores instead the possibility that infectious disease constrained the spread of dogs into Neotropical environments. Four diseases are considered, all likely to be native and/or endemic to South America: canine distemper, canine trypanosomiasis, canine rangeliosis, and canine visceral leishmaniasis caused by infection with Leishmania amazonensis and L. colombiensis. The paper concludes by suggesting ways in which the hypothesis that disease constrained the expansion of dogs into South America can be developed further.  相似文献

Four models of modern human origins were described and discussed by Aiello (Aiello, L. (1993) American Anthropologist 95: 73–96. She distinguished them as the African Replacement Model, the African Hybridization and Replacement Model, the Assimilation Model, and the Multiregional Model. All of these models have been modified and refined following further research and development by their proponents, but this is now leading to some confusion in testing the models. Whereas developments of the African Replacement Model have often been given distinct names, quite different versions of the Multiregional Model are still referred to under the original name. New ways of distinguishing the models are proposed, and the suggestion is made that some versions of the Multiregional Model should now be subsumed under the Assimilation Model, while others could perhaps be known under the term Multiregional Model 2.Quatre modèles représentant les origines de l'homme moderne furent décrits et discutés par Aiello (1993): le Modèle Africain de Remplacement (African Replacement Model), le Modèle Africain d'Hybridisation et de Remplacement (African Hybridization and Replacement Model), le Modèle d'Assimilation (Assimilation Model) et le Modèle Multirégional (Multiregional Model). Suite à de nouvelles recherches et de nouveaux développements, chacun de ces modèles a été modifié et affiné par ses partisans, ce qui, à ce jour, a mené à une certaine confusion lorsqu'il s'agit de tester ces modèles. Alors que les développements issus du Modèle Africain de Remplacement ont souvent reçu des noms à part, plusieurs variantes, toutes plutôt différentes les unes des autres, du Modèle Multirégional ne sont toujours connues que par leur nom d'origine. Ici je présente de nouvelles propositions ayant comme but de faciliter la distinction entre différents modèles. Je propose également que certaines variantes du Modèle Multirégional devraient à présent être comprises dans le Modèle d'Assimilation, tandis que d'autres pourraient peut-être prendre le nom de Modèle Multirégional 2 (Multiregional Model 2).  相似文献

Public space is constructed as heterosexual space in at least two senses. First, heterosexuality in public is regarded as unproblematic, whereas lesbian and gay identities are policed by subtle or overt means. Second, heterosexuality is not obviously marked in public. In this article these positions are used as a starting point to investigate the complexities of the relationships between heterosexuality, homosexuality and the public and private spheres. Much of the discussion takes as its basis the media coverage of New Zealand's lesbian and gay pride parades. Recent heterosexist discourse in New Zealand implies that gay men and lesbians are leaving the private sphere and are forcing a politicisation of both the public sphere and the metaphorical space of the private, heterosexual mind. A discursive inversion occurs whereby the homosexual subject becomes powerful and tyrannous, and the heterosexual is coerced and oppressed. Crucial to such discourse is a mobilisation of the conservative tendencies of liberalism, and an attendant denial of the privileged position granted to heterosexuality .  相似文献
