Advances in the Household Archaeology of Highland Mesoamerica

Recent investigations and reconsideration of households in the Mesoamerican highlands illustrate the central role of domestic spheres of interaction to the broader cultural dynamics of the region over four millennia. Methodological advances in the analysis of past houses permit more sophisticated social reconstructions of the spaces and activities that constituted domestic life for the diverse peoples of the region. Current studies highlight the economic interdependence and diversification of households, their strategic flexibility in affiliation, the integrative ritual practices undertaken within domestic spaces, the material correlates of prestige competition between households, and the manner in which households articulated with a larger social universe.     

Response to the Commentaries by Vessuri, Elzinga and Fouch��

The Matthew and Matilda Effects in science were coined in 1968 (Robert K. Merton) and in 1993 (Margaret W. Rossiter) respectively, as tools to analyse the reward systems of science. By proposing the African Eve Effect in science as a third effect, the original scope for analysis of these systems is broadened from the social structure of science to the anthropological dimension of science. Similarly, the ‘psychosocial processes’ that were considered as affecting the reward systems (Merton, Science 159:56–63, 1968) are extended to include discursive practices. The African Eve Effect refers to the scientific notion of the ‘African Eve’ (or mitochondrial (mtDNA) Eve), a concept put forward by scientists to designate the genetic mother of all modern humans. Three discursive conventions constitute the African Eve Effect and together shape patterns of the distribution of recognition for scientific work: projecting imaginative geographies of otherness onto the frontiers of science; collecting, transporting and enframing material and ideas according to a Western epistemological order; and ‘evolutionising’ nature and the human in science. The objective of this paper is to specify and illustrate an experimental tool for analysing the entanglement of the reward system in science with culturally fashioned imaginaries and agendas.     

Sailing Rock Art Boats

Amongst the thousands of Bronze Age rock art images that are found along the paleogeographic coast lines of southern Scandinavia the most ubiquitous is the boat. A few are furnished with what look like a mast or sail. These attributes have largely been ignored or explained away as features or objects other than rig because it is widely accepted that the sail was not used in Scandinavia until the 8th century AD. But what if after all they really are depictions of rig? Might this suggest that the sail was not only known but perhaps used here over a 1,000 years earlier than previously accepted? Starting from the bases of the images and the environment in which they are found, this paper asks whether vessels of the types we believe belonged to the Scandinavian Bronze Age could have been sailed? These evaluations led to a series of sail trials in a canoe undertaken in the archipelago of the Swedish west coast in the late summer and autumn of 2005. The successful results of these trials were later transferred to the Tilia, a full-scale reconstruction of the Hjortspring boat, a vessel dated to 350 BC but believed to belong to a long-established boatbuilding tradition stretching back into the Bronze Age. This is the report of the hypothesis behind these trials as well as their planning, execution and immediate results.     

Human occupation of South Eastern Altai highlands (Russia) in the context of environmental changes

Multidisciplinary investigations including geomorphological and geoarchaeological approaches, litho-stratigraphic and pedogenetic analysis accompanied by radiocarbon dating show the contrasting human environmental changes within the highlands of the Russian Altai since the late Paleolithic. Radiocarbon ages of fossil soils formed at 1,475–1,730 m a.s.l. indicate draining of the ice-dammed lake in the Kurai basin before the beginning of the Holocene and disintegration of the Chuya lake into several shallow but quite spacious reservoirs by 8,223?±?181 cal. BP. Using archaeological sites as spatio-temporal markers allows reconstructions to be specified based on geological data. Archaeological site distribution in the Chuya valley between the Chuya and Kurai basins indicates that all cataclysmic flood events related to the Holocene hydrological changes occurred before the Scythian epoch. Due to the redeposition of most Paleolithic finds in the region, they should be carefully examined before they are utilized for any reconstructions. Using fossil and contemporary soils as an independent informative climatic proxy archive supports the conception of generally more humid and warmer climate conditions in the first half of the Holocene within the SE Altai and a more arid and cold climate in the second one. The repeated climate deteriorations that caused glacier expansion and the progressive aridity intensification in the region along with the sociopolitical reasons are the major factors that controlled the habitat of nomadic communities and cultures shifting within the SE Altai in the second half of the Holocene. Anthropogenic impact together with the progressive aridization led to the deforestation of the eastern part of the Chuya depression.     

A Statistical Examination of Flake Edge Angles Produced During Experimental Lineal Levallois Reductions and Consideration of Their Functional Implications

Recent studies have indicated that Levallois-style core reduction offered potential practical benefits to hominin populations. However, none of these studies have yet considered one of the most important functional attributes of flake tools, which is edge angle. To address this shortcoming, we statistically examined flakes produced experimentally during “classic” or “lineal” Levallois core production and reduction. The primary aim of our analyses was to statistically test the null hypothesis of “no difference” between the edge angles of “Levallois” products and the flakes involved in their production. We employ existing edge angle analytical techniques and develop new comparative methodologies to assess flake blank standardization through the case of Levallois core reduction. Having determined the statistical properties of our experimental Levallois reductions, we thereafter evaluated to what extent edge angles produced may, or may not, have been useful to prehistoric hominins. Our analyses demonstrated that the experimentally produced Levallois edge angles were indeed statistically different from the flakes involved in their production. These differences were evident both in terms of relatively higher (i.e., more obtuse) edge angles than debitage flakes and in being significantly less variable around their higher mean edge angles compared to debitage flakes. However, based on current knowledge of how flake edge angle properties relate to issues of functionality, such differences would not have been detrimental to their functionality. Indeed, the edge angle properties they possess would have provided distinct benefits to hominins engaged in their manufacture. Most notably, Levallois-style core organization and reduction would have provided hominins with a reliable means of consistently producing flakes (i.e., “Levallois flakes”) possessing average flake angles that are beneficial in terms of providing a viable cutting edge yet not being so acute as to be friable upon application. Hence, edge angle properties join an array of other features that provide logical motive for why hominins may have organized core production and reduction around Levallois-style patterns at various times and places during the Mid-Late Pleistocene.     

From universal history to globalism: What are and for what purposes do we study European ideas?

Globalism is probably the most frequently used term describing our current age. Found in many contexts, it is often a vague concept referring to a host of different figurations of post-industrial society. European expansion, the growth of the global economy, mass immigration and the planetary expansion of international relations are merely some of the phenomena associated with globalism. Yet globalism taken in its most neutral form of global history is not merely a trendy catch-all phrase for the challenges of our age but has its origins in the efforts of the enlightenment—to rewrite the theological universal histories of the Middle Ages. There is a close relationship between the historiography of universal history and the current ideology of globalism. By juxtaposing the two main strands of universal history (the universal history of mankind vs. the cyclical history of individual peoples) to the problem of European identity, I show that the theoretical problems which caused the demise of universal history continue to plague globalism. Such an analysis of the ideological foundations of globalism is central not only to the current debate on the (re-) construction of European history, but also in the discussion on what constitutes European ideas.
