Africa: East Africa (Geographic Keyword)
26-50 (100 Records)
First developing around 8,000 years ago, pastoralism in Africa has continued as a flexible and dynamic mode of subsistence. One key feature of this dynamism is mobility, which is crucial for many East African pastoralists today to access seasonally available pasture and water. In areas of unpredictable rainfall, mobile pastoralism permits more people to live in dry lands than do other subsistence strategies. How the earliest herders in Tanzania used the landscape is still relatively unknown....
The EAST Typology: A Remedy for Eastern Africa’s "Lithics Systematics Anarchy" (2019)
This is an abstract from the "Recent Advances and Debates in the Pleistocene Archaeology of Africa" session, at the 84th annual meeting of the Society for American Archaeology. Eastern Africa boasts the world’s longest archaeological record, more than 3,4 million years so far. And yet, that record defies easy synthesis due to "lithics systematic anarchy." Archaeologists working in Eastern Africa describe and measure stone tools in so many different ways, that detailed comparisons within...
Ecological and Cultural Impacts of Colonialism on Mauritius (2024)
This is an abstract from the "Islands around Africa: State-of-the-Art and Future Directions" session, at the 89th annual meeting of the Society for American Archaeology. The colonization of Mauritius exemplifies the role played by humans in altering the ecosystems of remote islands. Previously uninhabited, it now has the highest population density of any African nation, and despite scant natural resources, also has one of the continent’s highest GDPs. Mauritius serves as an ideal case study...
Economic Changes through Time along the Tanzanian Swahili Coast, as Seen through the Examination of Non-ferrous Metals and Metallurgical Technologies (2023)
This is an abstract from the "Archaeological Science and African Archaeology: Appreciating the Impact of David Killick" session, at the 88th annual meeting of the Society for American Archaeology. Historic Swahili towns along the East African coast played prominent roles in the triangular Indian Ocean maritime trade linking East Africa with India and the Persian Gulf/Red Sea, but the impact and extent of economic changes through time in these towns are still poorly understood. Examining...
Establishing Baselines for Stone Tool Variation Across the Early Pleistocene: A Least Effort Approach (2023)
This is an abstract from the "Variability: A Reassessment of Its Meaning, Afforded Range, and the Relation to Process" session, at the 88th annual meeting of the Society for American Archaeology. Our understanding of the evolution of human behavior is largely predicated on how stone tools vary through time and across space. Despite a long history of research, the behavioral processes associated with Early Pleistocene lithic technology remain debated. Some research suggests that lithic...
Ethno-Archaeometry of Ochre Mineral Pigment Extraction, Transport, and Use in the Kenya Rift Valley (2018)
Ochre occurs in African archaeological sites from the later Middle Pleistocene to the ethnographic present. Ochre is used worldwide for symbolic and functional purposes, and is often considered to be evidence for symbolic behavior by cognitively modern Paleolithic humans. Geochemical provenience analysis, complemented by ethnographic studies of ochre source exploitation, transport, and use, can elucidate whether culturally mediated source exploitation differs significantly from a least-cost...
Feeding the Pre-Aksumite and Aksumite Society: Subsistence Strategies of Cities, Towns, and Urban Centers in the Horn of Africa (800 BCE–900 CE) (2021)
This is an abstract from the "Cultivating Cities: Perspectives from the New and Old Worlds on Wild Foods, Agriculture, and Urban Subsistence Economies" session, at the 86th annual meeting of the Society for American Archaeology. Local and long-distance trade and productive agricultural systems contributed to establishing complex socioeconomic institutions in the Horn of Africa between 800 BCE and 900 CE. Several important urban centers and towns, such as Yeha, Aksum, and Matara, emerged...
Fire in the Early Pleistocene: Evidence for the Use of Fire by Hominins at the 1.5 mya Site of FxJj20 AB, Koobi Fora, Kenya (2018)
The Cooking Hypothesis contends that fire use became common in the Early Pleistocene and was part of a suite of characters that were associated with the appearance of Homo erectus. The morphological changes associated with H. erectus support this hypothesis. Archaeological evidence for the control of fire in this time period is generally sparse, and arguments for controlled fire at early sites have been controversial. Here we present evidence for fire use by early hominins at the open-air site...
Friends and Enemies: Heritage Ethnography in the Shadow of the State (2018)
Engaged archaeology and public anthropology depend on the goodwill, or at least tolerance, of numerous publics. This is frequently understood to mean local communities and nearby residents, but projects can live or die according to the will of groups less often discussed as part of the target public: authority structures such as permitting agencies or even national governments. How do such organizations figure into the "public" of public scholarship? What happens when research is pressured to...
Getting to Know the Neighbors: Commensal Insights into Human-Ecosystem Dynamics (2018)
Advances in zooarchaeological method and theory, increased attention to the recovery and analysis of microfaunal remains, and multidisciplinary collaborative research have generated increasingly nuanced understandings of past human-animal relationships. This paper provides a brief introduction to archaeological investigations of commensal fauna, highlighting the myriad ways that research focused on the commensal niche sheds new light on past societies and ecosystems. A case study from Makangale...
GIS-Based Approaches to Obsidian Studies in Eastern Africa (2023)
This is an abstract from the "Recent Advances in Material Sourcing and Provenience Studies in Africa" session, at the 88th annual meeting of the Society for American Archaeology. Studies of obsidian transport during the Late Pleistocene of eastern Africa have been largely productive for reconstructing raw material procurement patterns and movement across landscapes. Due to a limited sample, however, these studies are often descriptive of particular sites and related explicitly to material...
The Glass Beads of Songo Mnara, Tanzania (2023)
This is an abstract from the "Current Research on Ancient Glass around the Indian Ocean" session, at the 88th annual meeting of the Society for American Archaeology. The archaeological site of Songo Mnara lies on a small island of the same name just to the south of Kilwa Kisiwani in Tanzania. It was occupied mainly in the fifteenth century CE and its assemblage of 7,444 glass beads provides us with a unique view into Indian Ocean trade to East Africa in this period. A comprehensive study of...
Habitat Preferences in Early Hominins and the Origin of the Human Lineage (2018)
Early hominins, such as australopithecines, are characterized by bipedality and enlarged posterior teeth. Originally, these traits were thought to be adaptations to an open environment. However, discoveries of older hominins, such as Ardipithecus that were possibly only occasionally bipedal and did not have enlarged teeth, have refocused the origins of early hominins within a much more closed, wooded setting. Even the later australopithecines are currently cast as inhabitants of mosaic...
Hilary Duke and Sonia Harmand—A New Approach to the Evolution of Early Pleistocene Hominin Cognition and Technological Change: Examining the Technological Context of LCT Emergence 1.8–1.76 Ma at Kokiselei, West Turkana, Kenya (2018)
The eastern African Early Pleistocene witnessed critical shifts in climate, environment, hominin anatomy and behavior. The lithic record shows change within this broader context. After 1.8 Ma, Large Cutting Tools (LCTs), such as bifaces, entered the hominin lithic repertoire. These artifacts are widely viewed as the first evidence of lithic shaping. Many archaeologists theorize both cognitive and practical differences between "flaking" and "shaping" among knapping strategies. Most of these...
Historical Ecology of Demographic and Economic Change in the Highlands of Western Kenya: Archaeobotanical and Mycological Evidence (2021)
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. The last several millennia of cultural history in the western Kenyan highlands have been marked both by punctuated periods of considerable demographic and economic change, and by continuous in-situ processes of genetic, linguistic, and economic interaction and admixture. Historical linguistic and archaeological models of the peopling of this region have, among...
The Importance of Archipelagoes (2024)
This is an abstract from the "Islands around Africa: State-of-the-Art and Future Directions" session, at the 89th annual meeting of the Society for American Archaeology. The role of islands in the western Indian Ocean has been well explored by archaeologists and historians, who point to a combination of natural and social advantages created by these bounded worlds. What has been less commented upon is the role of archipelagoes as crucial units of exploration. In this paper, I review the...
Imports and Outcrops: Characterizing the Baantu Obsidian Source and Artifacts from Mochena Borago Rockshelter, Wolaita, Ethiopia, Using Portable X-Ray Fluorescence (2023)
This is an abstract from the "Recent Advances in Material Sourcing and Provenience Studies in Africa" session, at the 88th annual meeting of the Society for American Archaeology. Forty-two obsidian samples from the Baantu obsidian source, including 25 outcrop samples and 17 surface artifacts, were characterized using portable X-ray fluorescence spectroscopy. These source data were then compared to 116 obsidian artifacts from Mochena Borago Rockshelter, excavated from levels dated to >50 ka BP...
Indian Ocean Comparative Dimensions of Slavery: Resistance and Memory from Mauritius (2019)
This is an abstract from the "Archaeological Approaches to Slavery and Unfree Labour in Africa" session, at the 84th annual meeting of the Society for American Archaeology. The materiality of slavery has received much attention over recent decades. Unequivocally focused on the Atlantic experience, comparative models from the Indian Ocean serve to enrich our understanding of slavery on a global scale. The body of literature on slave artefacts, mortuary practices, and diet highlight the nuances...
Indian Ocean Glass Beads from Miyoba Mound in the Kafue River Floodplain, Zambia (2023)
This is an abstract from the "Current Research on Ancient Glass around the Indian Ocean" session, at the 88th annual meeting of the Society for American Archaeology. This paper reports on an assemblage of Indian Ocean glass beads excavated from the Middle Iron Age mound of Miyoba in western Zambia, at the hook of the Kafue River. Miyoba was a long-occupied settlement during the late first and early second millennium CE represented by approximately 5 m of occupation debris that includes house...
Inferring Behavior from Damage Patterns: Bipolar Knapping and Nutcracking (2023)
This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Little is known about behaviors associated with the percussive technology of the Early Stone Age (ESA). Primatology provides a rare opportunity to observe how percussive behaviors produce damage patterns on stone tools. Although primate behavior provides a framework for inferring behaviors associated with ESA percussive tools, the distinction between...
The Influence of Raw Material Availability on Lithic Assemblage Variability in the Koobi Fora Fm. (Kenya) (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. A defining feature of human tool use compared to our closest living relatives is the transport of tools. This distinction is most evident in the Early Stone Age where transport is a feature of even the earliest industries. Spatial variability in raw material proportions has often been assumed to reflect transport patterns; however, these measures must be...
Iron Age Agriculture at the Multi-Component Site of Kakapel Rockshelter, Western Kenya (2019)
This is an abstract from the "African Archaeology throughout the Holocene" session, at the 84th annual meeting of the Society for American Archaeology. The domestication of African cereals and origins and spread of plant agriculture in eastern Africa remain poorly understood. Questions about the timing of farming, crop packages, and correlations with migration events, endure largely due to a lack of paleobotanical recovery and high-resolution dating on inland eastern African sites. In this...
An Isotopic Study of Diet at Mtwapa, Kenya (15-18th c CE) (2024)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. This project investigates the diet and foodways at Mtwapa, Kenya, on the East African coast during the 15th to 18th century. During this period, local East African populations negotiated Portuguese colonialism in the region. Stable carbon and nitrogen isotopic analyses were conducted using bone collagen from 28 individuals interred at Mtwapa, Kenya. 13C...
"The Land is now OK": Three Centuries of Marakwet Settlement on the Elgeyo Escarpment, Northwest Kenya (2019)
This is an abstract from the "African Archaeology throughout the Holocene" session, at the 84th annual meeting of the Society for American Archaeology. Situated within the Great Rift Complex of northwest Kenya, the Elgeyo Escarpment and surrounding region has been home to Marakwet communities for the last three hundred years. Many of these communities inhabit settlements which span diverse ecosystems, from semi-arid bush to highland forests. In tandem with changes in local lifeways and...
Landscape Evolution, Digital Terrain Analysis, and the Integrity of Surface Assemblages: A Case Study from the Koobi Fora Formation (2018)
Lithic surface scatters comprise a large proportion of the archaeological record but their value for understanding human behavior is often doubted. Modern geomorphological processes often laterally displace and selectively bias surface assemblages of artifacts. The predictable effects of displacement on the condition, weathering and size distributions of lithic assemblages is better understood. While topography is known to play a role in this process, the degree to which topographic variables...
