Getting “Out of Africa”: Sea Crossings,Land Crossings and Culture in the Hominin Migrations

Palaeoanthropologists and archaeologists have advanced a wide range of explanatory narratives for the various movements of Homo erectus/Homo ergaster, and the first modern Homo sapiens, “Out of Africa”—or even back again. The application of Occam's razor—a parsimonious approach to causes—gives a more cautious approach. There is nothing in the available evidence that would require the ability for a human water crossing from Africa before the later Pleistocene, whether across the Strait of Gibraltar, the Sicilian Channel or the southern Red Sea (Bab el-Mandab). A parsimonious narrative is consistent with movements across the Sinai peninsula. The continuous arid zone from northern Africa to western Asia allowed both occupation and transit during wet phases of the Pleistocene; there is no requirement for a “sponge” model of absorption followed by expulsion of human groups. The Nile Valley as a possible transit route from East Africa has a geological chronology that could fit well much current evidence for the timing of human migration. The limited spatial and temporal opportunities for movements “Out of Africa,” or back again, also puts particular difficulties in the way of the gene flow required for the multiregional hypothesis of the development of modern Homo sapiens.     

From the Ground Up: Agency,Practice, and Community in the Southwestern British Bronze Age

Embodied, sensual, engagements between people, earthly elements, and celestial bodies during focused, periodic acts of ritual construction and artifact deposition in the southwestern British Bronze Age resulted in the remaking of identities, local communities, symbolic/mythical knowledge, and the landscape itself. To appreciate how material culture, time, and space were employed to define the criteria by which people understood themselves and their world necessitates an archaeological focus upon shared practices in particular settings that served to define rules of engagement with the environment based upon shared human perceptions. Agency appears in this encounter as central in the construction and perpetuation of symbolic perception, shared social memory, and community identity.     

Linking Theory and Evidence in an Archaeology of Human Agency: Iconography,Style, and Theories of Embodiment

Many of the theories that inspire agency approaches in archaeology identify deep philosophical problems with other lines of thought. This creates challenges for identifying methods: do radical theories require radical methods? Choosing as a case study one of agency’s interpretive frameworks (embodiment) and, further, a single class of evidence (anthropomorphic imagery), I argue that the answer is “no.” In this case, familiar art historical methods, deliberately played off one against the other, provide a middle range framework for linking theory and evidence.     

Zooarchaeology and Historical Archaeology: Progress and Prospects

This review assesses the development and current status of zooarchaeological research in historical archaeology. Analytical issues in recovery, identification, quantification and interpretation are discussed with particular reference to assemblages from historical sites. The results section summarizes the substantive contributions zooarchaeological studies of historical assemblages have made to our understanding of past diet, food production systems, social and cultural variation, and archaeological interpretations. The last four decades of research has provided a strong basis for future analyses that draw together diverse strands of zooarchaeological, historical, scientific, and anthropological evidence.     

Civilization and Barbarism: When Barbarism Builds Cities

Around the mid-nineteenth century, D. F. Sarmiento introduced in Argentine literature the duality of “civilization and barbarism,” assuming that it was, at that time, an inescapable model in the analysis of society. Early in the 1880s, when the “conquest of the desert” came to an end and conflicts between city inhabitants and their urbanistic and “civilizing” urban plannings, vis-à-vis the rural populations that assumedly resisted change, worsened, the model acquired a new meaning. Taking one particular case of analysis, the foundation of the city of La Plata in lands owned by the Estancia Iraola, this paper uses archaeology to explore the limitations and falsehoods of such duality, jointly with the assumption of a simplistic relation of determinism between an environment and a particular human group.     

Exploring the Archaeology of the Modern City: Issues of Scale,Integration and Complexity

Historical archaeologists have advocated the need to explore the archaeology of the modern city using several different scales or frames of reference—the household and the district being the most common. In this paper, we discuss the value of comparisons at larger scales, for example between cities or countries, as a basis for understanding archaeology of the modern western city. We argue that patterns of similarity and dissimilarity detected at these larger scales can (and should) become part of our interpretive and explanatory armoury, when it comes to understanding patterns and processes at smaller scales. However, we also believe that these larger scale enquiries do not by any means exhaust (or diminish the importance of) the site- or household-specific questions that continue to demand adequate answers. By reporting some of the thinking behind the work that has been done in Melbourne, Sydney and shortly to begin in London, we seek to more clearly establish the value of this broader comparative agenda in urban historical archaeology.     

Reverse Engineering the Ceramic Cooking Pot: Cost and Performance Properties of Plain and Textured Vessels

Ceramic cooking pots throughout the world vary in exterior surface treatment from smooth to roughly textured. An intriguing example of this variation occurred in the Puebloan region of the southwestern United States where cooking pots changed from scraped plain to highly textured, corrugated vessels between the seventh and eleventh centuries AD, and then reverted back to plain-surfaced by the fifteenth century. To investigate potential cost and performance differences between plain and corrugated cooking pots, a set of controlled experiments were performed, which document manufacturing costs, cooking effectiveness, and vessel durability. These experiments indicate that while corrugation may have increased manufacturing costs, neck corrugations improved vessel handling, upper body corrugations yielded greater control over cooking, and basal corrugations extended vessel use-life. Discerning the explanatory significance of these results for cooking pot change in the Southwest and elsewhere requires additional data on the contexts in which these pots were made and used.     

New Perspectives on Early Regional Interaction Networks of East African Trade: A View from Tsavo National Park,Kenya

Archaeologists are interested in understanding whether cross-cultural contact catalyzed by exchange of commodities is a means for people to acquire new technology and cultural ideas. This paper reports the results and analysis of archaeological investigations in Tsavo National Park, Kenya in 2001 and 2004 that have recovered evidence of indirect contact between late pastoral neolithic (PN) herders and early iron working (EIW) communities. Analysis of stylistic motifs on ceramics used by both PN and EIW people show that socially constructed notions of aesthetics are similar, implying that a strong cultural connection between the two groups may be possible. New lexico-statistical analyses and archaeological data from Tanzania corroborate that the prehistoric East African milieu was more complex than previously believed. However, pastoralists in Tsavo show no evidence of utilizing iron technology or altering their subsistence strategies among the > 10,000 artifacts spanning 4,000+ years of prehistory recovered in the 2001 field season. Thus, long-distance and long-term contact between socially connected groups possessing different technological and subsistence foundations does not necessarily lead to a diffusion of new survival strategies.Les archéologues sont intéressés à comprendre la diffusion technologique et culturelle préhistorique [Les archeologues se sont interestesa comprendre la diffusion prehistorique de la technologie et de la culture]. Le contact entre les cultures catalysées par l'échange des produits est des moyens pour que les personnes acquièrent la nouvelle technologie et les idées culturelles. Cependant, le point auquel certaines idées sont acceptées ou rejetées demeure irrésolu. [Quand le contact contre-culturelle s'allie avec l'exchange de produits, les deux fournissent les nouvelles idees culturelles et technologiques aux gens. Mais, le point d D'autres données sont nécessaires pour augmenter nos compréhension de l'échange des idées entre les groupes de personnes et comment des changements de technologie. Les investigations archéologiques en parc national de Tsavo, Kenya dans 2001 ont récupéré l'évidence du contact indirect entre les bouviers néolithiques pastoraux (PN) en retard et les premières communautés du fondre de fer (EIW). L'analyse des motifs stylistiques sur la céramique utiliser par des personnes de PN et d'EIW prouvent que les notions socialement construites de l'esthétique sont semblables, impliquant qu'un raccordement culturel fort entre les deux groupes peut être possible. Les nouvelles analyses lexico-statistiques et les données archéologiques de Tanzanie corroborent que le milieu africain est préhistorique était plus complexe que précédemment cru. Cependant, les bouviers préhistorique dans Tsavo ne montrent aucune évidence d'utiliser la technologie de fer ou de changer leurs stratégies de subsistance parmi les > 10.000 objets façonnés enjambant les années 4.000+ de la préhistoire récupérées dans la saison de 2001 champs. Ainsi, contact à longue distance et long terme entre les groupes socialement reliés possédant différentes bases technologiques et de subsistance ne mène pas nécessairement à une diffusion de nouvelles strategies de survival.     

Ethnoarchaeology of Domestic Space and Spatial Behaviour Among the Tiv and Ungwai of Central Nigeria

An attempt has been made in this paper to use ethnoarchaeology to clarify our understanding of aspects of domestic space and spatial behaviour among the Tiv and Ungwai peoples of Central Nigeria. Indeed, the work is in several senses, a comparative study of two ethnolinguistic groups who occupy a similar ecological niche with broadly similar sociopolitical organisation. This mode of organisation is non-centralized in character. In addition, the two peoples had a tradition of hilltop occupation in ancient times. Differences in topography (hilltops for the ancient settlers and lowlands for the present-day peoples) have affected not only the compound layout of each of these ethnic groups but also among other features, the architecture of their houses. Given the limited available archaeological data including charcoal samples for dating, one is not yet able to ascribe specific functions to some of the structures identified on the archaeological sites (hilltops). This will be better addressed as research progresses.Quelques tentatives ont ete faits dans cet article pour se servir de Iethnoarchaeologie pour expliquer les divers aspects de lespace domestique et des caracteres de loccupation lespace parmi les Tiv et les Ungwai de la region centrale du Nigeria. En fait, ce travail est en grandes measures une etude comparative des deux groupes ethnolinguistiques occupant le meme crenau ecologique ayant largement la meme organization socio-politique. Le mode dorganisation est du type non centralize. De plus les deux groupes ethniques ont une tradition de locucpation des peuples anciens centres sur le haut de la colline. Des differences en topographie (le haut des collines pour le anciens occupants et la plaine pour les habitants actuels) n ont pas seulement eu effets sur la generalite de la maniere dont les concessions des ces groupes ethniques se presentent mais aussi larchitecture de leurs maisons sont parmi les traits particuliers importants. A cause du numbrer restreint de donnees disponibles en ce moment, nous ne sommes pas encore en mesure dattribuer certaines functions aux structures identifiees aux chantiers archaeologigues (au sommet des collines). Ces functions seront mieux traitees au fur et a mesure que lon avance dans nos recherches.     

L'«École de l'ETH» dans l'œuvre de Gaston Bachelard

We retrace here spectral presence in the work of Gaston Bachelard which we call «The School of the ETH». We have chosen three fundamental figures: hermann Weyl, Wolfgang Pauli and Gustave Juvet. For the first one, we consider his central and permanent place in the Bachelardian constitution of a philosophy which seeks to be at the height of the new «physical geometry» rigorously constructed in a Riemannian spirit. As for Pauli, we show an unsuspected affinity which is backed up by the remarkable analyses brought to it by philosophy: from the urgent construction of a «quantic metaphysics», founded on the implications of aPauli principle well understood, to the idea of a «metaphysical particle», going on to the decisive and so promising stakes of the «postulate of non-analysis». In the framework of this convergent polyconstruction of the «surrationalist», enterprise, we treat the third figure, less known but equally important, of the mathematician-philosopher Gustave Juvet.
