Indigenous African sheep genetic resources have been classified into two main groups, fat-tailed and thin-tailed sheep. The fat-tailed sheep are the most widely distributed, being found in a large part of North Africa (from Egypt to Algeria) and in Eastern and Southern Africa (from Eritrea to South Africa). The thin-tailed sheep are present mainly in Morocco, Sudan and in West Africa. African sheep were domesticated outside Africa. They share a common ancestry with European and Asian sheep. Archaeological information supports separate introductions and dispersion histories for the African thin-tailed and fat-tailed sheep. The first sheep entered Africa via the Isthmus of Suez and/or the southern Sinai Peninsula, between 7500 and 7000 BP. They were likely of the thin-tailed type. Fat-tailed sheep entered Africa through its northeastern part and the Horn of Africa. Mitochondrial DNA analysis supports a common maternal ancestral origin for all African sheep, while autosomal and Y chromosome DNA analysis indicates a distinct genetic history for African thin-tailed and sub-Saharan fat-tailed sheep. The main ancestral population of southern African fat-tailed sheep likely originated in East Africa. Further work is needed to assess the possible dispersion of sheep from western Africa to the southern African regions.  相似文献

The end of apartheid has precipitated rapid rethinking of South Africa's position in relation to the rest of Africa and the global arena. Whereas a substantial literature already exists on the country's evolving post-apartheid foreign policy, this article offers one of the first critical analyses of its emerging external economic relations. Although clearly the economic giant of the Southern African Development Community, South Africa does not perform as well on all economic and social indicators as many people, especially South Africans, believe. South African businesses' perception of, and experiences in, the rest of Africa are assessed in relation to emerging patterns of trade and investment there. Selected advertisements and associated imagery deployed by firms in support of their strategies are analysed in the context of domestic transformation and the opening of new horizons abroad. South African foreign direct invest-ment (FDI) is increasingly diversified, both sectorally and geographically, although large firms dominate the profile. South African-based transnational corporations are also becoming increasingly influential global players. FDI and development aid inflows to South Africa, and in relation to the rest of Africa, are analysed and their implications explored. Far Eastern investment rose fast as part of a growing global inflow until 1997/8; more recent figures are disappointing. This reflects political and security concerns, as well as vulnerability to rapid flow reversal in the increasingly important portfolio investment market.  相似文献

Sub-Saharan Africa has long been seen as lacking the potential for autochthonous urban development, and Near Eastern and European contact provided ready explanations for the emergence of precolonial cities across the continent. In the past few decades, the pace of archaeological work on African cities has accelerated, and archaeologists have increasingly deployed a functional model of the city, in which cities are defined in relation to broader hinterlands rather than particular traits. As a result, deeply rooted urban traditions have been identified in all corners of the continent. Despite the antiquity of urban traditions across Africa, however, long-distance forces clearly had wide-reaching impacts on urban developmental trajectories, and proponents of the functional model have yet to explain the specific role of long-distance forces in the process of urbanization. This review examines how multiscalar forces shaped urban trajectories in West Africa, specifically. I examine how local political entrepreneurs took advantage of the opportunities provided by local, interregional, and global forces, resulting in a heterogeneous set of urban traditions across West Africa, ranging from trading entrepôts to regional capitals. Throughout I emphasize how local agency articulated with multiscalar social and economic forces, transforming the nature of regional integration, economic specialization, and the materialization of social difference, defining qualities of urban life.  相似文献

Food production originated in various ways in different parts of the world. Plant domestication with the adoption of agriculture has been successful in some areas, but not in others, where animal domestication with nomadic pastoralism proved to be more effective. Likewise, the preceding phases of pre-adaptation and development of a broad spectrum of wild resource exploitation followed different pathways, according to the locally available resources, climatic and geographic conditions, and social organizations. Northern Africa greatly contributed to the understanding of the origin of food production under preconditions that differed from those in the Fertile Crescent. Apart from a narrow strip along the Nile valley, northern African lands are arid and scarcely productive for agriculture. Nevertheless, early studies interpreted northern African archaeological records of the Early and Middle Holocene according to the traditional north-western Mediterranean and Near Eastern frames of reference. Consequently, terms such as Epipalaeolithic, Mesolithic, and Neolithic were uncritically applied to northern African contexts. This paper compares and discusses the evidence for food production in the Near East and northern Africa, considering the question of introduction or local breeds of domesticated animals in the Maghreb and the Sahara. It then reviews the relevant data for long-held diffusionist models of pastoralism into Africa to provide a different perspective and the proper means of interpretation of the northern African archaeological records. Finally, it examines some recent findings from the Tadrart Acacus, in the Libyan Sahara, which contribute to clarification of distinctive African pathways and propose an alternative model for the beginnings of food production.  相似文献

Einkorn (Triticum monococcum L.) was one of the first cereals to be domesticated in the Old World ca. 10,000 years ago and to spread towards Europe and North Africa. Its cultivation declined before the Iron Age and it remains today only as a relic crop in remote areas. To investigate if the geographic distribution of genetic diversity in modern einkorn landrace accessions could be informative about the movement of this crop during prehistory, we genotyped 50 accessions of einkorn from Europe, North Africa and the Near East. Using nuclear and chloroplast microsatellites and clustering methods, we detected two main gene pools in einkorn. The distribution of these lineages revealed differences between accessions from Morocco and the Iberian Peninsula from the rest of Europe and the Near East and suggests different regional dynamics in the spread of this crop.  相似文献

Domestication is an ongoing co-evolutionary process rather than an event or invention. Recent zooarchaeological and animal genetics research has prompted a thorough revision of our perspectives on the history of domestic animals in Africa. Genetic analyses of domestic animal species have revealed that domestic donkeys are descended from African ancestors, opened a debate over the contribution of indigenous aurochs to African domestic cattle, revealed an earlier and possibly exogenous origin of the domestic cat, and reframed our vision of African dogs. Genetic diversity studies and mapping of unique traits in African cattle, sheep, goats, pigs and chickens indicate adaptations to regional environmental challenges and suggest hitherto unknown and complex patterns of interactions both among Africans and with Southwest Asia and other Asian regions on the Indian Ocean. This article argues against the static perspective on domestication as invention and for viewing it as a dynamic, locally based and continuing process.  相似文献

In recent years, mitochondrial diversity of goats has been extensively studied, in order to shed light on domestication processes. There are limited studies on genetic diversity and demographic history of Anatolian goat breeds, and these studies have focused only on modern goats. Until today, no research has been conducted on DNA analysis of ancient Anatolian goats. In the present study, seven ancient DNA samples of goat remains from Van‐Yoncatepe archaeological site in Eastern Anatolia, Turkey, dating 1000 BC, were successfully extracted and amplified for the first time. A 230‐bp fragment of mitochondrial DNA Hypervariable Region 1 of the samples was analyzed. All of the ancient sequences belonged to haplogroup A, which is the most widely distributed and frequently encountered haplogroup in modern goats. The results also pointed out that Anatolian ancient goats might have contributed to the genetic structure of modern goats in the Near East, the Mediterranean Region and South‐Southeastern Asia.

The purpose of this article is to suggest: (1) That a particular model of writing African church history inherited from the historiography of European mission has influenced the way in which the trans-African history of Christianity in Africa has been presented. It is argued that this model has encouraged an episodic view of the Christian past, through its documentary emphasis on the last two centuries. (2) That this model was both implicit and unchallenged in the theological trends of the post-colonial period, with their programmatic emphasis on indigenization and inculturation. The work of the vast majority of African theologians, and hence of church historians outside Africa, envisaged a model of the 'discontinuous past' premised on the idea that Christianity was to be understood in terms of export and import or 'early' north African and 'later' southern African engagement. This model is here labelled the 'discontinuity paradigm'. (3) That a new model for the writing of church history in Africa should be attempted. An 'adaptive similarities' model is proposed which sees the history of the church in Africa against the template of analogous conversion–adaptation–fissiparation movements in the earlier periods of the church's existence. The essay proposes a pan-African church history 'project' which focuses its work on constructing this model from regional church history efforts (Sundkler) and which attempts to isolate the recurrent themes and patterns of African Christianity (the thematic–chonological matrix) as interpreted within the wider African context (the geographical–cultural matrix).  相似文献

The analysis by nuclear activation techniques and by inductively coupled plasma mass spectrometry combined with an UV laser of a large number of gold coins issued in the Arab Empire from the seventh to the 12th century ad showed that several different supplying sources were used, according to the region and to the period. The aim of this paper is to point out the circulation of gold in the Near and Middle Eastern mints of the Arab Empire and to make a parallel with the mints’ policies running in the other regions of the Empire, such as North Africa, the Iberian Peninsula and the Sicily. The identification of different gold ores by means of characteristic trace elements indicated recycling of the ancient coinage and, after ad 750, the minting in the entire Arab Empire of different new gold ores: Egyptian type, North Eastern type and West African type. The analysis of a small number of silver coins from the same periods and regions also showed a change in the ore supply after ad 750.  相似文献

Based on archival research in Ghana and Britain, this article documents the sustained but failed attempts of working‐class West African seamen to repatriate to the colonies with their European wives during the interwar years. Colonial authorities crafted policies to prevent these couples from making British West Africa home because they feared that the presence of European women living ‘in native fashion’ with their African husbands would destabilise colonial race relations. After discussing the origins of this policy in the context of the 1919 race riots that swept Britain's port cities, the article draws on the case of a West African man married to a German woman to illuminate how concerns about race, sex, gender, nationality and class informed the politics of repatriation to British West Africa during the interwar years.  相似文献

From the 16th century onward, various European nations shared fishing spaces off the coast of Newfoundland in an effort to provide salt-fish products to supplement increasing European demand. Faunal remains excavated at seasonal and permanent Newfoundland fishing stations indicate that pigs were the primary mammal species consumed by cod fishermen. It is not clear whether these pig remains derive from salt pork and/or live pigs imported from Europe or, rather, from pigs bred and raised in Newfoundland. Based on the notion that Newfoundland-raised pigs would have had greater access to marine-derived foods from nearby fisheries compared to their European-raised counterparts, we analyzed stable carbon and nitrogen isotope values from 28 pigs and 117 other faunal specimens from Dos de Cheval (EfAx-09) and Ferryland (CgAf-02) in order to identify individuals with marine or terrestrial isotope dietary signatures. Results indicating two distinct groups of pigs with mean δ13C and δ15N values differing by ∼6‰ and ∼9‰, respectively, suggest differing pig-product origins at each site. This method for identifying the transatlantic origin of pig remains has potential to shed light on patterns in the provisioning of the early European transatlantic fishing industry and inter-community relations. It may also allow for the development of more sophisticated body part representation models for zooarchaeological reconstruction of barreled salt pork use.  相似文献

Small enterprise clusters are viewed as an important means of promoting competitive small‐firm development even in contexts of unstable markets and weak states. Yet the emergence of successful enterprise clusters in developing regions of Southern Europe, Asia and Latin America contrasts with their conspicuous absence in Africa. This article challenges ahistorical and culturalist explanations regarding the lack of successful enterprise clusters in Africa through a comparative analysis of three dynamic and increasingly globalized informal manufacturing clusters in two different regions of Nigeria. Focusing on a Muslim Yoruba weaving cluster in the town of Ilorin in south‐western Nigeria, and two Christian Igbo shoe and garment clusters in the town of Aba in south‐eastern Nigeria, this article explores the role of culture, religion and the state in shaping informal economic governance in an African context. An account of the varied and complex history of these Nigerian enterprise networks reveals both their capacity for institutional innovation and economic linkages across ethnic, religious and gender boundaries, as well as their vulnerability to fragmentation and involution in the context of liberalization, state neglect and political opportunism. Far from demonstrating the inadequacies of African cultural institutions, the slide of African entrepreneurial networks into social disorder and economic ‘ungovernance’1 is traced to the destructive impact of neoliberal reforms in a context of poverty and formal institutional exclusion.  相似文献

The Indian Ocean has long been a forum for contact, trade and the transfer of goods, technologies and ideas between geographically distant groups of people. Another, less studied, outcome of expanding maritime connectivity in the region is the translocation of a range of species of plants and animals, both domestic and wild. A significant number of these translocations can now be seen to involve Africa, either providing or receiving species, suggesting that Africa’s role in the emergence of an increasingly connected Indian Ocean world deserves more systematic consideration. While the earliest international contacts with the East African coast remain poorly understood, in part due to a paucity of archaeobotanical and zooarchaeological studies, some evidence for early African coastal activity is provided by the discovery of early hunter-gatherer sites on offshore islands, and, possibly, by the translocation of wild animals among these islands, and between them and the mainland. From the seventh century, however, clear evidence for participation in the Indian Ocean world emerges, in the form of a range of introduced species, including commensal and domestic animals, and agricultural crops. New genetic studies demonstrate that the flow of species to the coast is complex, with more than one source frequently indicated. The East African coast and Madagascar appear to have been significant centres of genetic admixture, drawing upon Southeast Asian, South Asian and Middle Eastern genetic varieties, and sometimes yielding unique hybrid species. The biological patterns reflect a deeply networked trade and contact situation, and support East Africa’s key role in the events and transformations of the early Indian Ocean world.  相似文献

The West African sahel and savanna are today home to diverse cattle breeds derived from complex social, political and environmental processes over at least the past four thousand years. Current evidence from the sahel and its floodplains indicates multiple sizes of cattle over time that may correspond to modern breeds. However, little is known about the cattle further south in the savanna, such as the West African Shorthorn. These humpless cattle are well adapted to the environmental conditions of more humid zones, including their significant resistance to trypanosomiasis, or sleeping sickness. In this paper I present new archaeozoological data from the Iron Age village of Kirikongo, Burkina Faso (100-1700 CE) that indicate the presence of small cattle in the 1st millennium CE similar in size to West African Shorthorn. These results are contextualized through comparisons with other archaeological sites and environmental data in Central West Africa, suggesting that small cattle are generally associated with the savanna environment over time, and their distributions may have oscillated with climatic changes. Lastly, interregional processes are assessed given Kirikongo’s evidence for small savanna cattle in western Burkina Faso and their subsequent adoption in the Inland Niger Delta of Mali.  相似文献

Abstract

Established during the colonial era, the majority of museums in Africa were modeled on their European counterparts. The period of Africanization that followed the independence of many African nations witnessed a dramatic increase in the number of Africans receiving higher education and specialized training. Institutions such as museums began to come under the leadership of indigenous Africans but, in most cases, the exhibits and their condition(s) remained the same. Today, African museums face new challenges: how can they become more relevant, both to the local communities they serve and to foreign visitors? How can they attract more visitors, especially from local communities? This article discusses the notion of ‘indigenous’ in an African context. It looks at the development of museums in Africa and their current metamorphosis into dynamic cultural centres that address pertinent social, cultural and even economic issues-in the face of dwindling government funding and increased modernization and globalization. It discusses several museums and how they are meeting these challenges, and how organizations such as AFRICOM (International Council of African Museums) and programmes such as SAMP (African–Swedish Museum Network) are contributing to the positive changes currently taking place.  相似文献

The Neolithic Revolution, constituting a shift from food acquisition to food production, came to Africa as it did to most of the rest of the world: through processes of transmission rather than through de novo innovation. In contrast with other regions the pastoral management of cattle, sheep and goats was widespread in Africa thousands of years before settled agricultural communities or the use of domesticated plants were in evidence ( 46, 35 and 10). We report here the discovery of haplogroup B in the first genetic analysis of an African archaeological sheep assemblage.  相似文献

This paper examines evidence for the origin of the tree Spondias mombin in Africa, where it is generally described as introduced from the Neotropics. Based on biogeographical, ecological, and historical evidence, this paper argues that the tree reached Africa via natural, long-distance dispersal, and should be considered an African native plant. The idea that it is introduced appeared in 1868, when it was a scientifically justifiable conclusion reflecting the limitations of nineteenth-century biogeographical knowledge. By the early twentieth century, representing Spondias mombin as a human introduction in Africa was no longer scientifically justifiable because of advances in knowledge of the African flora and plant dispersal ecology. Nonetheless, most authors continued to represent the tree as introduced, in part because such representation was consonant with dominant images of the African environment: (a) that the continent had suffered extensive deforestation in the recent past, and (b) that Africa's flora was depauperate in fruit trees prior to the coming of Europeans. Recent authors continue to describe Spondias mombin as introduced because they have not sufficiently considered the historic contexts of primary and secondary sources on Neotropical plant introductions in Africa. This paper concludes that the human role in creating the African portion of the trans-Atlantic tropical flora has been overemphasized. Natural plant dispersal across the Atlantic may be more frequent than generally accepted.  相似文献

The Inuit sod winter house or iglu has undergone a host of alterations over the past millennium, as housing styles were accommodated to changing local milieus during the colonization of the Eastern Arctic. Many of these changes relate to subtle shifts in gendered work and household social relations, and in Labrador from the eighteenth century some appear to reflect engagements with a more or less hostile European discourse on architectural modernity. Far from a static form subjected to convulsive contact-era transformations, however, dwellings were gradually remade in the context of a long-running Inuit effort to house work and sociality within a meaningful space.  相似文献

This article examines attempts to negotiate a perceived residual dominance of settler populations in South Africa and Zimbabwe by means of developmental and cultural policies deemed necessary to restore sovereignty to Africans. Indigenisation has become a preferred strategy for reconstructing post-colonial states in Africa: indigenisation of the economy as part of a Third Chimurenga in Zimbabwe and Black Economic Empowerment in the socio-cultural context of Ubuntu in South Africa. These are issues arising from the regional legacy of contested and uneven transitions to majority rule. Identifying how governments frame the ‘settler problem’, and politicise space in doing so, is crucial for understanding post-colonial politics. Indigenisation in Zimbabwe allows the government to maintain a network of patronage and official rhetoric is highly divisive and exclusivist although couched in terms of reclaiming African values and sovereignty. Revival of Ubuntu as a cultural value system in South Africa facilitates a more positive approach to indigenisation, although Black Economic Empowerment displays elitist tendencies and cultural transformation remains controversial and elusive. The perceived need to anchor policy in socially acceptable (i.e., ostensibly indigenous/traditional) contexts has become a prominent feature of post-colonial politics and is indicative of an indigenous turn in Southern African politics.  相似文献

Europe has taken unprecedented levels of peacetime defensive actions against the perceived demands by African migrants for “absolute hospitality”. In collaboration with politicians across the Mediterranean, European political leaders are authoring a chronotope that removes Africa and Africans from global time. This discursive vision rests on an epistemological reorientation coding all Africans as potential migrants capable of threatening European and African sovereignty and security. This conceptual realignment has seeded a defensive assemblage of coercive controls, sociologies of knowledge, and a campaign to generate sedentary African subjects. Ultimately it is engendering “containment development” aimed at geographically localising Africans’ desires and imaginations. In an era of planetary entanglement and exchange, this discursively and materially excludes Africans from what it means to be fully human.  相似文献
