Anticipated mobility and its archaeological signature: A case study of Folsom retooling strategies

This essay highlights the value of anticipated mobility for untangling variability in prehistoric stone tool manufacture. To do so, it explores the organization of weaponry production at a series of Folsom campsites via the highly visible archaeological signature of Folsom fluting. A model of weaponry replacement based on deep planning and anticipation of needs is proposed, according to which Folsom hunters commonly replace their projectile points as they wear down, break or are lost, but on fewer occasions engage in the mass production of fluted points. This technological organization is consistent with a highly mobile way of life in which advanced planning buffers the risk associated with limited or stochastic access to good quality lithic raw materials. The model is then put to the test at the Lindenmeier site in northern Colorado. The spatial patterning of fluting activities in two discrete areas of the site demonstrates contrasting strategies of point manufacture: conservation versus gearing up (creation of a surplus). It is argued that these patterns represent distinct facets of a single technological organization.     

Serpentine Hot Springs,Alaska: results of excavations and implications for the age and significance of northern fluted points

The dispersal of Homo sapiens across the New World is one of the greatest chapters in the history of our species; however, major questions about this late Pleistocene diaspora remain unanswered. Two contentious issues are the timing of colonization of the Bering Land Bridge and origin of Clovis, which at 13,000 calendar years ago is the earliest unequivocal complex of archaeological sites in temperate North America, known by its specialized fluted spear points. One hypothesis is that fluting technology emerged in Beringia and from there was carried southbound, with fluted points becoming the diagnostic “calling card” of early Paleoindians spreading across the Western Hemisphere. Fluted points have long been known from Alaska, yet until now they have never been found in a datable geologic context, making their relationship to Clovis a mystery. Here we show that a new archaeological site at Serpentine Hot Springs, Bering Land Bridge National Preserve, Alaska, contains fluted points in a stratified geologic deposit dating to no earlier than 12,400 calendar years ago. Our results suggest that Alaska's fluted-point complex is too young to be ancestral to Clovis, and that it instead represents either a south-to-north dispersal of early Americans or transmission of fluting technology from temperate North America. These results suggest that the peopling of the Americas and development of Paleoindian technology were much more complex than traditional models predict.     

Pattern or bias? A critical evaluation of Midwestern fluted point distributions using raster based GIS

Because the abundance and distribution of fluted points has long played a critical role in interpreting various colonization and settlement scenarios of North America, correlations made between fluted point distribution and patterns of Early Paleoindian land use need to be critically evaluated. Gauging not just the source, but also nature of bias within distributional data of this sort is important if we are to improve the accuracy and reliability of our inferences concerning the timing, source, and mode of the radiation of human populations throughout the western Hemisphere. In this study, I employ a raster based GIS approach using a continuous non-site distribution of fluted biface distributions across a twenty-nine county (46,000 km²) study area of northern Illinois. The results suggest that when sources of bias are revealed and controlled for, significant settlement patterning can not only be identified, but more accurately interpreted.     

Weak Ties and Expertise: Crossing Technological Boundaries

In this article, we question how new technological traits can penetrate cohesive social groups and spread. Based on ethnographic narratives and following studies in sociology, the hypothesis is that not only weak ties are important for linking otherwise unconnected groups and introducing new techniques but also that expertise is required. In order to test this hypothesis, we carried out a set of field experiments in northern India where the kiln has been adopted recently. Our goal was to measure the degree of expertise of the potters distributed between early and late adopters of the kiln. Our results are discussed in the light of oral interviews. Our conclusions suggest that expertise is a necessary, albeit not sufficient, condition for weak ties to act as bridges and thereby for new techniques to spread. As an example, they explain how turntables could have been adopted by potters from the northern Levant during the third millennium BC.     

The Lower Palaeolithic on the northern plateau of the Iberian Peninsula (Sierra de Atapuerca,Ambrona and La Maya I): a technological analysis of the cutting edge and weight of artefacts. Developing an hypothetical model

This article analyses the relationship between the weight and cutting edge of lithic artefacts from the main Lower Palaeolithic sites on the northern plateau (Meseta) of the Iberian Peninsula. The weight and cutting edge of a tool determine its cutting ability and the amount of force it is capable of, making them extremely important aspects of study to further our understanding of the potential capacity for human intervention in the environment. However, the analysis of these features has not received much attention in the ongoing debate on the Palaeolithic era in Europe. This study argues that the quantitative and qualitative technological analysis of these two aspects is of fundamental importance in determining the potential of lithic assemblages.     

INHABITING NEW LANDSCAPES: SETTLEMENT AND MOBILITY IN BRITAIN AFTER THE LAST GLACIAL MAXIMUM

Summary.   This paper explores the debate over the reoccupation of northern Europe after the last glacial maximum. Previous contributions to this debate have focused more on the timing of this event, rather than the technological and mobility strategies that enabled people to move into new landscapes. It is argued that a more detailed examination of the archaeological evidence from specific sites can provide a more nuanced understanding of these issues and can highlight the variety of technical economies employed in the late glacial. These concerns are explored through a case study from the Vale of Pickering in northern England.     

Gender and place influences on health risk perspectives in northern Canadian Aboriginal communities

Developing a better understanding of the factors underlying health and environmental risk perspectives has been the focus of significant research in recent years. Although many previous studies have shown that perspectives of risk are often associated with gender, sociocultural variables and place, our understanding of the relationship between these factors and risk remains equivocal. A research study was undertaken to develop better insights into the understanding and perspectives of various types of health risks in two sets of northern Canadian Aboriginal communities – the Yellowknives Dene First Nation communities of N'Dilo and Dettah in the Northwest Territories and the Inuit communities of Nain and Hopedale in Nunatsiavut. Gender was found to have a limited overall effect on risk perspectives, consistent with other studies that found no gender differences in communities stressed by multiple and concurrent risks. Nonetheless, subtle gender differences were seen in the qualitative responses, with women focusing more on community impacts and mitigating actions. Threats to ‘place-identity’ associated with changes in traditional lifestyle and connection to the land were strongly associated with risk perspectives. These results reinforce the need to be cautious in making assumptions about the complex effects of community and personal attributes, such as gender and gender relations, in assessing the factors underlying risk views and concerns. They also suggest the importance of gathering multiple types of data (both quantitative and qualitative) in order to fully assess the effects of both gender and place. Ultimately, understanding risk in a northern context requires recognizing the unique circumstances and identities of northern Aboriginal peoples.     

Why Are Clovis Fluted Points More Resilient than Non‐Fluted Lanceolate Points? A Quantitative Assessment of Breakage Patterns Between Experimental Models

For decades, archaeologists have wondered whether the Clovis Palaeoindian (c.11 600–10 800 radiocarbon years bp ) practice of ‘fluting’, a flake removal technique that creates a distinctive shallow channel extending from the base of the projectile point towards the tip, bestowed a functional advantage over non‐fluted projectile points. Using analytical modelling and static engineering experiments, Thomas et al. (2017) found that points that more effectively redistribute stress and relocate damage can absorb significantly more energy, last longer and remain intact relative to points that do not experience these phenomena. In general, stress redistribution and damage relocation is significantly more likely to occur in fluted points, as opposed to non‐fluted points, suggesting that fluting acts as a ‘shock absorber’. Here, we present a comparative quantitative assessment of breakage patterns between Thomas et al.’s (2017) experimental points that shows those experiencing stress redistribution and damage relocation were also able to significantly better resist breakage, and to incur non‐catastrophic breaks, than points that less effectively redistribute stress and relocate damage. This more beneficial breakage pattern explains the material advantages provided by stress redistribution and damage relocation, and hence the potential motivation for fluting. This does not preclude the possibility that the process of fluting was accorded significance beyond its possible utilitarian value. Additional tests will be necessary to further resolve the ‘shock‐absorbing’ capabilities of fluting.     

CUT ABOVE THE REST: A MULTI-DISCIPLINARY STUDY OF TWO SLATE KNIVES FROM FORAGER CONTEXTS IN COASTAL NORWAY

Slate was a prominent tool material in the Scandinavian Stone Age. However, details of tool function have relied on morphology and have added little to our understanding of their role in hunting and processing. Here, we demonstrate that it is possible to identify both the use-wear traces and residues from slate knives from northern Norway. By applying a multi-disciplinary approach incorporating experimentation, use-wear and organic residue analyses, we identified residues, including seal hair, and use-traces which indicate the tools were used to process fresh marine mammals.     

Deglaciation and Colonization: Pioneer Settlements in Northern Fennoscandia

We present new data on Early Mesolithic settlements in northern Sweden and discuss the process of pioneer colonization. A new set of radiocarbon dates from archaeological sites push deglaciation of northern Fennoscandia further back in time and demonstrate the rapid arrival of pioneer settlers. Environmental data reveal a highly productive early postglacial setting with plant communities unmatched in present ecosystems. The chronological and technological setting supports immigration from the north and northwest with pioneers relying on a long history of enculturating northern subarctic landscapes.     

Late pleistocene human adaptations in eastern North America

Eastern North America in late Pleistocene times was characterized by two major environmental regions: a periglacial tundra or open spruce parkland and an extensive complex boreal/deciduous forest in the unglaciated, lower latitudes. These environments selected for different adaptive strategies on the part of human foraging groups—known archaeologically as Paleoindians. Those in the tundra and tundra-forest region were highly mobile, possibly specialized hunters, exploiting caribou; those in the forest were generalists, exploiting a variety of subsistence resources with a less mobile settlement system. There is little evidence in either area for hunting of Pleistocene megafauna. These differences in adaptive strategies are reflected in the record of sites and isolated fluted points scattered throughout the region, as well as aspects of tool technology, function, and patterns of stone use.     

Confocal laser scanning microscopy: a flexible tool for simultaneous polarization and three-dimensional fluorescence imaging of archaeological compact bone

Wide-field polarized light and epifluorescence microscopy have been used to enhance analysis of archaeological bone tissue, providing information on bone formation, modeling, pathology, preservation, age estimation, and biomechanics. Though valuable, these techniques are limited by their inability to remove out-of-focus light and view multiple levels of a sample, restricting our understanding of the three-dimensional (3-D) microarchitecture of compact bone. Modern technological advances, such as microscopic computerized tomography, allow increasing resolution in 3-D bone imaging, but do not allow fluorescence labeling or polarized-light analysis. Confocal laser scanning microscopy (CLSM) is a valuable tool for 3-D histology. However, its application to the study of compact bone is lacking, especially in archaeological and forensic sciences. The current study investigated CLSM as a tool for fluorescence and polarized-light microscopy of archaeological compact bone in order to demonstrate its advantages. Standard techniques and CLSM are compared in their suitability for imaging well preserved archaeological bones from the Dakhleh Oasis, Egypt. CLSM's high resolution, multi-channel, two- and three-dimensional capabilities augment the flexibility and creativity of compact bone imaging and have the potential to increase the accuracy of quantitative medical and anthropological histomorphometric techniques. CLSM is specifically suggested as a useful tool for the investigation of ancient bone fluorescence caused by the presence of tetracycline and/or other fluorochromes.     

Drivers of technological richness in prehistoric Texas: an archaeological test of the population size and environmental risk hypotheses

This paper reports a study that sheds light on an issue that is important for understanding human behavioral evolution—the factors that influence hunter-gatherers’ decisions regarding the number and degree of specialization of their tools. Two primary drivers of technological richness and complexity have been proposed in the anthropological literature: population size and environmental risk. In general, ethnographic studies tend to support environmental risk as the primary driver, whereas the limited number of archaeological studies that have been carried out seem to support population size. These findings are difficult to reconcile because problems exist for both sets of studies. The present study was designed with these problems in mind. We used an archaeological dataset to test which of the hypothesized driving factors—population size or environmental risk—best explains changes in technological richness. More specifically, we investigated whether changes in the number of point types in Texas from the first occupation more than 13,000 years ago to the Late Prehistoric period, around 400 years ago, are better explained by environmental risk or by population size. Bivariate correlations and a generalized linear model indicate that temporal changes in point-type richness in Texas are significantly associated with changes in one of our proxies of risk—global temperature. We found no relationship between temporal changes in point-type richness and changes in population size. Thus, the results derived from this study are consistent with the environmental risk hypothesis and inconsistent with the population size hypothesis.     

Quantification of Fracture Propagation Velocity Employing a Sample of Clovis Channel Flakes

Velocity-dependant lithic fracture surface features are employed to determine precursory loading rate. The methodology is applied to a sample of Clovis channel-flake scars revealing that some Clovis points were fluted using pressure-flaking techniques.     

Identification of PbO (BaO) faience from an early and middle Warring States period cemetery at Zhaitouhe,northern Shaanxi,China

Low‐temperature vitreous materials fluxed with lead (and barium) appeared in the early Warring States period (c.fifth century bce ) in ancient China. A range of lead vitreous products fluxed with the same agent, including faience/glass beads, glazed pottery and Chinese blue (purple) pigment, were developed subsequently. This study carries out scientific analysis of six vitreous beads unearthed from the Zhaitouhe cemetery site in northern Shaanxi dating to the early and middle Warring States period to investigate their chemical composition, microstructure and coloration. The lead (and barium) vitreous beads identified here are some of the earliest lead vitreous materials discovered in China so far, and therefore important for the study of the development of lead vitreous technologies in ancient China. This paper also points out that it is meaningful to evaluate the lead glass, glazed pottery and barium copper silicate pigments as a whole technological assemblage given their close relationships.     

The Lantern-Bearers of the history of technology

Historians of technology need to focus more on studying human experiences of technological change rather than technological objects. Aesthetic debates over ‘realism’ and ‘romance’ in the later nineteenth century suggest that greater attention to the inward world of lived experience can enhance our understanding of historical experience. The well-known writer Robert Louis Stevenson experimented with a variety of new forms of romance to write about contemporary events in the South Seas with primary attention to inward experiences of technological change, as opposed to accounts of technological objects.     

The Micro-foundations of Regional Branching—the Case of Digitization of Publishing

Abstract

Theorizing within evolutionary economic geography on regional branching of industries has so far been depicted as evolving through routine replication among different economic actors that hold various degrees of relatedness. Methodologically, related variety and unrelated variety have been studied quantitatively, treating relatedness between economic agents as pre-defined industrial classifications. This represents a need for a complementary qualitative and in-depth understanding of how knowledge is re-combined in various settings. Based on a qualitative case study in the publishing industry, whose technological platforms and business models are currently facing severe challenges associated with digitization, this paper seeks to improve our understanding of how knowledge is re-combined and re-applied in various ways. The paper explores and discusses how this industry branches out into new activities, and reflects upon the channels through which these processes unfold. How is the old and the new in the economy bridged? How is the relationship between specialization and diversification played out? In this sense, the paper seeks to contribute to improving our understanding of the epistemic micro-foundations for regional branching and economic development.     

Multi-Ethnic Settlement and Interregional Exchange in Pimampiro,Ecuador

Abstract

This paper reports on recent archaeological investigations at the sites of Shanshipampa and La Mesa in the Pimampiro district of northern Ecuador, a zone rich in archaeological resources about which relatively little is known. Within the context of Andean archaeology, this region is particularly significant insofar as it is described in early historic accounts as an important center of interregional trade. The role of trade in the shaping of ethnic identity and the evolution of complex societies has received relatively little attention in Andean scholarship. The present study expands our understanding of the modes, content, and significance of interregional interaction in the Andes by directing attention to the evidence for long-distance trade, trans-zonal connections, and multi-ethnic settlement in the northern highlands.     

Anglo‐Saxon Style Pottery from the Northern Netherlands and North‐Western Germany: Fabrics and Finish,Regional and Chronological Patterns,and their Implications

This paper presents the results of a study of Anglo‐Saxon style pottery in the northern Netherlands and north‐western Germany, involving macroscopic and microscopic analysis of fabrics and finish. Both regions show similar developments in form and decoration in the pottery of the fourth and fifth centuries ad , the late Roman and Migration period, resulting in the typical decoration and shapes that are known as the Anglo‐Saxon style. In the northern Netherlands, this style is traditionally associated with Anglo‐Saxon immigrants. It has, however, been suggested that this style was, rather, part of an indigenous development in areas in the northern Netherlands where occupation was continuous, though influenced by stylistic developments in north‐western Germany. That hypothesis is supported by the analysis of fabrics and finish presented here. The characteristic of fabrics and surface treatment indicate technological continuity. The use of local clay sources for Anglo‐Saxon style pottery and for contemporary regional types indicates that most of the Anglo‐Saxon style pottery in the northern Netherlands was not brought by Anglo‐Saxon immigrants or as imports, but must have been made locally. That applies to settlements with continuous habitation, as well as settlements in the coastal area that were not inhabited during the fourth century ad .     

THE CHALLENGE OF ‘TECHNOLOGICAL CHOICES’FOR MATERIALS SCIENCE APPROACHES IN ARCHAEOLOGY*

Recently several anthropological and sociological studies have interpreted technologies as cultural choices that are determined as much by local perceptions and the social context fly any material constraints or purely functional criteria. Using the example of ceramic technology we consider how materials science studies can contribute to and benefit from this understanding of technology as a social construct. Although we acknowledge some potential difficulties, it is our contention that both materials scientists and archaeologists have gained much and have much to gain by cooperating together to study ancient technologies, and that the concept of ‘technological choices’can facilitate a wider consideration of the factors shaping technological developments.
