Raw material availability,flaking quality,and hunter–gatherer technological decision making in northern Tierra del Fuego Island (southern South America)

The technological organization and lithic raw material procurement of Holocene hunter–gatherers have been topics of considerable interest in northern Tierra del Fuego Island. Ongoing archaeological investigations indicate that most of the rocks employed by native human populations came from secondary deposits of fluvio-glacial and marine origin. However, a primary geological source for two distinctive lithologies has been recently discovered near the Chorrillo Miraflores Valley (Tierra del Fuego, Chile). These raw materials became the focus of further research since one of them (a silicified tuff) has been identified in several archaeological sites of Tierra del Fuego. Some of these sites are located more than a hundred kilometers away from the source. A regional survey of potential lithic sources along with petrographic and geochemical analyses confirmed that the silicified tuff is only available at Chorrillo Miraflores. Here we present the technological analysis of artifacts manufactured on Miraflores silicified tuff that were recovered from the Argentine portion of northern Tierra del Fuego composed of Espíritu Santo and San Sebastian Capes. The role of utilitarian currencies in the prehistoric use of this lithology is assessed through the application of the Metcalfe and Barlow (1992) field processing model. The results show that this raw material may not have been exclusively selected for its flaking quality, although an alternative functional efficiency hypothesis is also introduced. Finally, its spatially restricted availability as well as unique macroscopic aspect suggests its selection and use may have been mainly influenced by social factors.     

Storage adaptations among hunter–gatherers: A quantitative approach to the Jomon period

Food storage economies among hunter–gatherers have been fundamentally important in research within anthropological archeology. It is well recognized that food storage was a key element in the evolution of hunter–gatherer societies. This paper examines storage facilities utilizing a digital planimeter to evaluate the volume and morphology of storage pits in the Jomon period (ca. 13,750–500 cal. BC). Quantitative analysis of Jomon storage pits shows temporal and spatial variability in terms of size. This research demonstrates that the quantitative analysis of storage pits is an effective way to improve our understanding of storage and its role in the Jomon economy in particular and subsistence adaptations in general. Thus, this approach has potential applications to other storage economies worldwide.     

Diversity in hunter–gatherer technological traditions: Mapping trajectories of cultural ‘descent with modification’ in northeast California

Recent work has demonstrated that technological traditions can be considered as systems of information transmission that operate on the principle of ‘descent with modification’. In this paper we present an ethno-historical case-study of northeast Californian hunter–fisher–gatherers. Our goal is to understand the factors generating long-term diversity in local material culture, and we begin by investigating the extent to which branching and reticulation explain variation in four distinct technological traditions – basketry, cradles, ceremonial dress and earth-lodges. We then examine whether these four traditions have been transmitted in tandem, or are characterized by entirely different descent histories. The results for this particular case-study suggest that the first three traditions have been closely associated during branching descent, while the earth-lodges appear to have entirely distinct transmission histories. The general analytical framework presented in this paper is readily exportable to other world regions, where local case-studies may generate contrasting insights into historically-contingent patterns of cultural inheritance. Further studies examining potential co-transmission of technological traditions are strongly encouraged as a welcome addition to the cultural transmission literature.     

The Fluted Point tradition and the Arctic Small Tool tradition: What’s the connection?

This paper presents a comparative study of two colonizing populations in the Americas: the Fluted Point tradition (FPt) and the early Arctic Small Tool tradition (ASTt) with the aim of understanding the role of lithic technologies in the colonization process. The FPt and ASTt are seen as residentially mobile groups with comparatively little reliance on food storage and minimal transportation aids. At the same time they also produced very similar flaked stone technologies that differed greatly from all later groups, being characterized by standardized core reduction, excellence in manufacture, production of a wide range of often hafted tools, use of the highest quality toolstones and a reliance on flaked stone, as opposed to ground stone, tools. The main advantage of these technologies is that they are not only flexible but can be rapidly produced. It is suggested that the key variable accounting for these choices is the lack of efficient transportation aids. In colonizing situations, the limited transport capabilities force populations to: (a) rely more on less predictable search and encounter methods of resource procurement and in turn, residential mobility to position people with regard to resources and (b) place a high premium on efficient time allocation to meet the excessive demands needed to maintain social contacts and mating networks amongst very low density populations.     

Caching your savings: The use of small-scale storage in European prehistory

Understanding of European prehistoric storage practices tends to focus on the long-term and large-scale storage of cereals from the Neolithic onwards. In addition, storage is often associated with the development of sedentism and social complexity. Through the use of anthropological and ethnographic data this paper demonstrates that storage by both hunter-gatherers and farmers is more complex. New storage categories, such as closed and open caches, and portable storage, are suggested as ways of understanding whether similar storage practices were used during European prehistory. We learn that although direct evidence for storage is difficult to find in the archaeological record, a combination of ethnographic data and indirect evidence demonstrates that storage, especially this use of small-scale storage, was practiced in prehistory. In the conclusion, this paper demonstrates that storage during the Mesolithic (11,300-6000 BP) would have played a vital role in the lifeways of hunter-gatherers and that for the Neolithic (6000-4500 BP) the use of small-scale storage of a variety of foods would have been equally important as the storage of grain.     

Canids as persons: Early Neolithic dog and wolf burials, Cis-Baikal, Siberia

Interpretations of dog burials made by ancient foraging groups have tended to be based upon our own relationships with such animals and modern western cosmological and ontological concepts. Osteological studies of early dogs often focus only on issues of taxonomy, and as a result very little is known about these animals’ life histories. Eastern Siberia has produced many Holocene dog burials, but these are typically not well described and the explanatory frameworks provided for them are very underdeveloped. Here we examine in detail two Cis-Baikal canid burials, one of a wolf and the other a dog, both in large Middle Holocene hunter-gatherer cemeteries. We link the mortuary treatment of these animals to other cultural practices, particularly the treatment of the human dead, and broader patterns in Northern human-animal relationships. This interpretive model is combined with detailed osteobiographies for the canids and contextual information for these and other dogs and wolves from Middle Holocene Cis-Baikal. It is argued that canids here were understood and treated in a variety of ways. We suggest that some animals with unique histories were known as distinct persons with ‘souls’ and because of this at death required mortuary rites similar to those of their human counterparts.     

Late Holocene climatic fluctuations and soil genesis in southern Patagonia: effects on the archaeological record

Geoarchaeological research conducted at five localities in southern Patagonia and Tierra del Fuego identified a mollisol within late Holocene aeolian and colluvial deposits associated with archaeological material. The mollisol's origin and development are related to an increase in humidity (c. 1000 BP) following an episode of severe drought during the Medieval Warm Period. Corroborating data is supplied from dendroclimatic and pollen studies. A drastic reduction in frequency of artefact distribution recorded at the sites studied corresponds to this pedologic event, suggesting a greater human presence at these sites during earlier, regional-scale arid conditions. However, the paucity of archaeological remains may also be the result of the low resolution of cultural evidence following the pedologic development due to superimposition over previous archaeological deposits.     

Standing at the gates of Europe: Human behavior and biogeography in the Southern Carpathians during the Late Pleistocene

This study presents a behavioral analysis of Middle and Upper Paleolithic lithic assemblages from 14 sites located in the southern Carpathian Mountains. Using a whole assemblage behavioral indicator, we show that the hominins that manufactured those stone tools do not appear to have differed in terms of the flexibility of the mobility strategies they employed to exploit their landscapes. Rather than biological change, we argue that large-scale climate changes are likely more important drivers of behavioral changes during the Late Pleistocene of the region, including during the Middle–Upper Paleolithic transition. These results agree well with the results of studies having employed this methodology in other regions, suggesting that this is a generalized feature of the transition across Eurasia. Recasting the transition as a mainly ecological rather than purely biocultural process allows us to generate new perspectives from which to approach the question of behavioral change during the Late Pleistocene, and ultimately suggests that the process referred to as the ‘Middle–Upper Paleolithic transition’ is essentially a brief segment of a much more extensive process driven by prehistoric human–environment interactions that would culminate in the highly logistical mobility strategies documented throughout the continent at the Last Glacial Maximum.     

Climate change, uncertainty and prehistoric hunter–gatherer mobility

The onset of Little Ice Age conditions in California’s Sierra Nevada mountains resulted in increased temporal and spatial variability, and hence uncertainty regarding the distribution and production of resources targeted by its inhabitants, the Western Mono. The Mono responded with a risk-averse strategy composed of lowland winter population aggregation supported by logistical forays and seasonal residential dispersals to the high country, both ways of averaging variance in environmental productivity. These patterns were reconstructed using surface archaeology, GIS, and two straightforward spatial statistics, nearest-neighbor and variance-to-mean ratios, that combined provide a robust, objective picture of population aggregation and dispersal and the scale of these phenomena in different environments and seasons. These diverse strategies conform to expectations regarding the best ways for hunter–gatherers to cope with uncertainty, particularly in mountain environments. Despite this, the residentially mobile aspect of the pattern is rare in mountains and probably the result of historical connections between the Mono and Great Basin groups employing similar behaviors. Ultimately, this research suggests that climate change and environmental variability condition risk-averse, satisficing economic behaviors focused more on security than optimization, implying that pronounced environmental variability runs counter to economic intensification and its association with the evolution of more complex societies.     

The technology of Stone Age colonization: an empirical,regional-scale examination of Clovis unifacial stone tool reduction,allometry, and edge angle from the North American Lower Great Lakes region

There is now broad consensus that the appearance of Clovis in Northeastern North America (Great Lakes, New England) represents a colonization pulse into recently deglaciated landscapes. Due to the increased resource uncertainty that comes with colonizing unfamiliar landscapes, it was hypothesized that the majority tool component of Clovis assemblages, unifacial stone tools, should have been knapped on tool blanks possessing the design properties of longevity and functional flexibility to facilitate exploration mobility and guard against the absence of toolstone sources in the new landscape. These properties are optimized by large, flat flakes, possessing large surface area relative to flake thickness. Since discarded and, at times, exhausted unifacial stone tools do not preserve the original dimensions of the blank upon which they were created – necessary items for a true test of blank morphology selection – this study presents a set of predictions for inferring whether Clovis unifacial stone tool blanks were selected for the properties of longevity and functional flexibility based on evidence that Clovis people actually capitalized on those properties. Due to the nature of Clovis unifacial stone tools, tool size was of necessity used as a proxy for tool reduction, on the grounds that smaller tools are more likely to have been resharpened than larger tools, at least in the case of unifacial flake tools. The results showed that less resharpened tools possessed flatter, less spherical shapes than the more resharpened tools, which possessed more globular, spherical shapes, suggesting Clovis foragers exploited the retouch potential afforded by the larger, flatter blanks. Edge angles showed no relationship with tool reduction, suggesting that Clovis foragers exploited the functional flexibility afforded by flatter blanks by adjusting the edge angle to be either higher or lower as needed. These results are consistent with the notion that human colonizers, who did not know the abundance or location of stone outcrops prior to settling an unfamiliar territory, not only “geared up” before leaving a stone source, but geared up as efficiently as possible by carefully selecting the blanks they chose to carry. Broader implications for such careful unifacial stone tool blank selection are discussed.     

Human corpse manipulation and the body as symbol: A case study from the Eastern Pampa–Patagonia transition (Argentina) during the Final Late Holocene

Human body manipulation and secondary burials are widespread funerary practices in many areas of the world. The archaeology of the Pampas and North-Eastern Patagonia, Argentina, is no exception. In this paper, archaeological case studies from the lower basin of the Colorado River during the Final Late Holocene (ca. 1000–250 years BP) are presented and discussed. Secondary burials were recovered that indicated an intentional manipulation of bodies. Evidences of cut marks and the coloring of bone surfaces were recorded. The bundles were composed of individuals of both sexes and diverse age categories. The Pampean region and North-Eastern Patagonia witnessed significant hunter–gatherer population dynamics during the last 1000 years BP. Climatic, ecologic, demographic, and economic explanations have been proposed as the background to these changes. In this paper, it is argued that accompanying these factors, as part of a broader socio-cultural scenario, were significant social interaction networks and processes of social complementarity between groups. In this context, it is proposed that the complexity observed in relation to the handling of bodies is part of a worldview in which the body was seen as material culture – as a symbol – that played an important role for the community in group identity maintenance in a cultural context undergoing significant organizational changes.     

THE PROVENANCE OF OBSIDIAN ARTEFACTS FROM THE WĀDĪ ATH‐THAYYILAH 3 NEOLITHIC SITE (EASTERN YEMEN PLATEAU) BY LA–ICP–MS

The geological sources of obsidian in the Red Sea region provide the raw material used for the production of obsidian artefacts found in prehistoric sites on both sides of the Red Sea, as far afield as Egypt, the Persian Gulf and Mesopotamia. This paper presents the chemical characterization of five obsidian geological samples and 20 prehistoric artefacts from a systematically excavated Neolithic settlement in highland Yemen. The major element concentrations were determined by SEM–EDS analysis and the trace element concentrations were analysed by the LA–ICP–MS method, an almost non‐destructive technique capable of chemically characterizing the volcanic glass. A comparison of archaeological and geological determinations allows the provenance of the obsidian used for the Neolithic artefacts to be traced to definite sources in the volcanic district of the central Yemen Plateau.
