Republic of Djibouti (Country) (Geographic Keyword)
276-300 (522 Records)
Home to Aksum and other highly-developed polities, the Tigrai Plateau is a leading contender for sub-Saharan Africa's richest center of ancient state formation. This and its susceptibility to environmental (climate and land cover) variation make the region compelling for evaluating whether environmental changes affected the trajectories of polities. Soils exposed by gullying are the longest continuous archives of environmental proxies in the region. Many proxies are affected by both climate and...
Least-Effort Knapping as a Baseline to Study Social Transmission in the Early Stone Age (2023)
This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Variation in lithics has been used as a mechanism to infer diachronic aspects of hominin behavior. The emergence of the Acheulean industry is considered a major milestone in the evolution of hominin cognition. This perspective is predicated on the idea that Acheulean large cutting tools (LCTs) require mental templates imposed through knapping and that LCTs...
The Legacy of the Foraging Spectrum and Mikea Ethnography: Do We Need Hunter-Gatherer Studies Anymore? (2024)
This is an abstract from the "Three Sides of a Career: Papers in Honor of Robert L. Kelly" session, at the 89th annual meeting of the Society for American Archaeology. One way to view the twentieth-century history of hunter-gatherer studies is as a long attempt to evaluate Victorian notions of foragers as primitive relics with actual data from real foraging peoples. This history came to a fiery climax during the Kalahari history debate of the 1990s, when researchers argued whether...

Levallois, Learning, and Lithic Variation: Results from Porcelain Flintknapping Experiments (2018)
The ability to transmit cultural information with high-fidelity across generations is a defining trait of modern humans. It is unclear, however, how and when this adaptation emerged in the human lineage. The earliest forms of human technology—stone artifacts—required knappers to understand raw material mechanics, as well as geometry (volume reduction, angles), and physics. Thus, it is often assumed that the spread of lithic technologies involved some degree of information transmission. However,...
Life in times of change – A bioarchaeological perspective on health and living conditions in Upper Nubia in the late 2nd and early 1st millennium BC (2017)
With the end of the Pharaonic Egyptian colonial occupation c. 1070BC and the increasing deterioration of climatic conditions, communities in Upper Nubia faced significant changes, both to the political structure (which may have affected trade networks), and to the agricultural potential of the region (e.g. availability of arable land). This presentation aims to elucidate if, and in what ways, these alterations impacted upon the living conditions of the people in the area, using the skeletal...
Lithic Analysis of GaJj17: a Middle Stone Age Locality in Koobi Fora, northern Kenya (2017)
The Koobi Fora region in eastern Turkana, northern Kenya, is known for its preservation of Plio-Pleistocene hominin fossils. However very little is known about the Middle Stone Age (MSA) from this region. Fossil and genetic evidence suggest modern humans originated in eastern Africa ~200ka, adding to the significance of this time period and region. In 2016, we excavated site GaJj17, an MSA site located in Area 104 of Koobi Fora. Here we present lithic analysis of recovered in situ and surface...
Lithic artifact production at the Large-scale Pharaonic chert quarries of Wadi el-Sheikh, Egypt (2017)
Recent research into quarrying and lithic production in Wadi el-Sheikh, Egypt by the University of Vienna has identified activities extending from the Middle Paleolithic to modern times. These include Middle Paleolithic use of surface materials, Neolithic chert quarrying, Pharaonic gypsum extraction, quarrying and production of groundstone, ochre collection, and small-scale independent modern salt quarrying. However, the most striking activities are the large-scale Pharaonic period chert...
Lithic Miniaturization and Behavioral Variability in Southernmost Africa 18–11 kcal. BP (2018)
Lithic miniaturization, the systematic production of small stone artifacts by controlled fracture, was a pervasive feature of late Pleistocene lithic technology. Smaller toolkits enabled humans to exploit raw materials more efficiently, to produce composite tools more effectively, to reduce a wider range of rocks, and to increase mobility by lightening toolkits. These benefits allowed humans to occupy a wider range of ecological niches. Archaeologists working in southern Africa have long...
Lithic Taphonomy and Digital Hydrogeologic Models: A GIS Based Approach to Understanding the Formational History of Surface Assemblages (2018)
Surface assemblages play an important role in understanding human behavior. However, modern erosional processes—specifically flowing water—can limit the behavioral inferences that can be gained from surface assemblages by transporting materials from their original discard sites. The influence of these processes can be observed in the size distribution and condition of surface lithic assemblages. The topography and geomorphology of the landscape heavily dictates the degree to which fluvial...
Local Responses to Global Events: Regionally Distinct Dietary Changes among Eastern African Herders at the Close of the African Humid Period (2018)
Changing human diets in eastern Africa across the end of the African Humid Period (AHP) have been inferred indirectly from cultural and faunal remains at archaeological sites. Stable isotope analysis (SIA, specifically δ13C) can measure diets directly, yet few studies have conducted SIA on human remains from this region. We present 25 new δ13C values from human tooth enamel recovered from archaeological sites around Lake Turkana (northwest Kenya) and on Lukenya Hill and Rigo Cave (southern...
The Location for the Origin of Domesticated Sorghum in Africa: A Brief Review of Some Cultures in the Sahara, Nile, and Sahel (2023)
This is an abstract from the "Subsistence Crops and Animals as a Proxy for Human Cultural Practice" session, at the 88th annual meeting of the Society for American Archaeology. Recent analyses have established the location for the origin of domesticated sorghum occurring in the far eastern Sahel of Sudan during the fourth millennium BC associated with the Late Neolithic Butana Group. For over a half century, sorghum domestication has been hypothesized as occurring somewhere in the Sahelian...
Long-Term Settlement in Plantation Regions of Unguja, Zanzibar (2021)
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. In this paper, I discuss the results of an archaeological survey conducted in 2019 in north-central Unguja, Zanzibar. The aim of the survey was to investigate the long-term settlement history of regions that were transformed in the nineteenth century by Omani landowners who developed an agricultural export economy using a labor force of enslaved East Africans....
Longevity and authority in a mobile world the megasites of the Ugandan grasslands (2017)
Much of the recent past of Great Lakes Africa is characterised by short-lived settlements and mobile societies, that produced ephemeral occupation sites. In part because of this, attention has long been drawn to sites like Bigo and Ntuusi which seem to offer much more substantive archaeological remains. Yet, notwithstanding the longevity of the latter and the extent of both, this is clearly not a simple occupation site featuring a large population. Rather it is much more effective to understand...
Luminescence Age Calculation Models, Termites, and Dune History in the Northern Kalahari Desert, Hwange National Park, Zimbabwe (2023)
This is an abstract from the "A Tribute to the Contributions of Lawrence C. Todd to World Prehistory" session, at the 88th annual meeting of the Society for American Archaeology. Archaeologists often accept optically stimulated luminescence (OSL) ages with less critical review than those derived from the more commonly used radiocarbon dating methods. This is largely because of an incomplete understanding of optical dating techniques and the modeling assumptions used to calculate these ages....
Macro- and Microscopic Effects of Heating in Lithics: Potential Indicators of Human-Controlled Fire? (2018)
Outside of clear association of human activities and fire features (e.g., a constructed hearth and artifacts), a perennial challenge persists in linking human/hominin behavior to the control of fire. This particularly vexes ongoing investigations to determine early human-fire interaction(s). Although natural landscape fires can be intense, their tendency to move quickly may limit modifications in lithic material at ground level. Studies examining the effect(s) of heating tool-stone at different...
Macrobotanical and Microbotanical Evidence for Plant Use and Consumption at Gede, Kenya (2024)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. Over the last several decades, excavations at numerous Swahili period sites along the East African coast have yielded a wide variety of data on economic and cultural practices during the last millennium BP. The results of intensive flotation recovery of macrobotanical remains from pit latrine sediments at housing structures are presented, providing direct...
Macroscopic Comparative Studies of Archaeological Data: Spatiotemporal Variability in Lithic Technology of Paleolithic Asia (2024)
This is an abstract from the "Big Ideas to Match Our Future: Big Data and Macroarchaeology" session, at the 89th annual meeting of the Society for American Archaeology. Comparative studies using archaeological data on a broad spatiotemporal scale can provide an overview for investigating significant questions in human history and can promote discussions among scholars from different disciplines. This talk will present the results of a quantitative analysis of lithic technologies from the...
Mai Adrasha and Its Neighbors (2017)
A team from UCLA in cooperation with the Tigrai Culture and Tourism Agency and the Authority for Research and Conservation of Cultural Heritage of Ethiopia has completed two excavation seasons at the site of Mai Adrasha located about 70 kilometers west of the ancient capital of Aksum. With the information gathered in these excavations, we can now begin to compare Mai Adrasha to neighboring sites and place it within its regional framework. Radiocarbon dates from the first season of excavation...
The Making of Agro-pastoral Landscape of the Tibetan Plateau: A Zooarchaeological Perspective (2018)
The vertical ingredient of the Tibetan Plateau plays a unique role in making of the highland agro-pastoral landscape. We divide the Tibetan Plateau into three eco-altitudinal zones: areas below 3,000 m.a.s.l.; areas between 3,000 and 4,200 m.a.s.l.; and areas above 4,200 m.a.s.l. Today, pastoralists and farmers utilize different faunal and floral taxa in the three zones, partly as risk aversion strategies. In this paper, I review the zooarchaeological evidence dated between 6,000 and 1,000 BP...
Malaria in the African Indian Ocean Islands: Prospects and Challenges for Biomolecular Archaeology (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. Malaria remains one of the most devastating infectious diseases affecting human populations, with over 200 million cases and 500,000 deaths annually worldwide, most of which focused on the mainlands of sub-Saharan Africa. While malaria is an “old” disease on the mainland dating back tens of thousands of years, its history on...
Mammalian Enamel Stable Isotopic (δ13C, δ18O) Evidence for Environmental Change during the MSA-LSA Transition at the Kisese II Rockshelter, Tanzania (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Environmental perturbations are invoked as an influence of hominin speciation, dispersal and technological innovations. Archaeological occurrences preserving the transition from the Middle Stone Age to the Later Stone Age are critical to gauging environmental influences of human adaptations, yet there is a dearth of well-dated sites in eastern Africa. The...

Mapping Historical Sacred Spaces in Southern Ethiopia (2018)
In 2011, we began a collaborative project with Boreda Gamo communities of southern Ethiopia to understand the spatial and historical relationships between settlements and sacred areas. Community elders guided us along winding footpaths that ascended 9 mountain tops leading to settlements that were first occupied in the early 13th century and have now been abandoned for nearly 100 years. Surrounding these historic settlements are sacred groves with springs, caves, and boulders that give physical...
Mapping MSA Deposits: Regional Geological Investigation of Upper Chari Member Sediments in the Ileret Region, East Turkana, Kenya (2017)
The Ileret region of the Koobi Fora Formation (KF Fm.), located in Kenya’s Turkana Basin, has historically been the focus of extensive archaeological research. Mid-Late Pleistocene units have previously lacked defined sedimentary beds due to an understudied unconformity of the upper Chari Member (1.34 Ma to 10 Ka). This represents a substantial limit to Middle Stone Age (MSA) research. Recent fieldwork (2016) incorporated a geoarchaeological survey of the upper Chari Member. Here we describe and...
