Humans and marine resource interaction reappraised: Archaeofauna remains during the late Pleistocene and Holocene in Cantabrian Spain

The exploitation of marine resources in Prehistory has traditionally been regarded as insignificant, at least until the late Upper Pleistocene. However, in recent years the systematic study of archaeofaunal remains with a marine origin has widened our knowledge of the role they played among groups of hunter–gatherers in Europe. This paper analyses the available data about the evidence for the exploitation of the different marine resources (molluscs, birds, mammals, crustaceans, echinoderms and fish) that have been recorded at archaeological sites in Cantabrian Spain in the late Pleistocene and early Holocene.With the information currently available, it is clear that although it is in the Mesolithic when archaeozoological remains with a marine origin are found most often, the exploitation of these resources in the region began in the Early Upper Palaeolithic.     

Plant Diversity in the Archaeological Record: A Means Toward Defining Hunter–Gatherer Mobility Strategies

The diversity and ubiquity measures of archaeological macrobotanical remains can be utilized to help define mobility strategies of hunter–gatherers. Differences in the diversity and ubiquity of plant remains are predicted to occur between different types of sites utilized by hunter–gatherers. Such sites include base camps of residentially and logistically mobile groups, as well as special-purpose sites usually associated with logistically mobile groups. The focus upon the importance of strategies of mobility and plant use instead of the typological determination of plant taxa allows for the use of specimen types in such analyses when scientific identifications are difficult to make. Data from the archaeological site of San Jacinto 1, located in northern Colombia, are utilized to examine this relationship.     

Ethnoarchaeological study of phytolith assemblages from an agro-pastoral village in Northern Greece (Sarakini): development and application of a Phytolith Difference Index

Phytolith assemblages are analysed in an ethnographic agro-pastoral community in Northern Greece. A new method for analyzing the data, combined with the concentrations of phytoliths per gram sediment, helps to differentiate diverse uses of space in the village. The Phytolith Difference Index (PDI) contrasts the phytolith assemblages in sediment samples from the region around the village least affected by human activities with those in the village and its immediate surroundings. The PDI reveals that many of the samples are dominated by the input of the stalks of the domestic cereal, rye, which is used for food, animal fodder and roof thatching. The PDI also differentiates between dung from mules or donkeys with dung from free ranging cows and goats. Activity areas analysed include storage areas, stabling areas, animal enclosures, floors from living areas that were repeatedly swept, hearths and open areas between structures. The combined use of the PDI, together with phytolith concentrations and phytolith morphotype analyses, may prove to be useful for deciphering activity areas in archaeological sites of not only agro-pastoralists, but also pastoralists and hunter–gatherers.     

The social role of food in the Natufian cemetery of Raqefet Cave,Mount Carmel,Israel

The archaeology of mortuary practices and related foodways in the Late Natufian (LN; ca. 14,000/13,500–11,700 BP) sheds light on the communal activities of the last hunter–gatherers in the Mediterranean Levant. We present a detailed analysis of the fauna from the LN cemetery of Raqefet Cave (Mount Carmel, Israel). Taphonomic evidence indicates that the animal bones are butchery and consumption leftovers. While the patterns of animal exploitation are reminiscent of Natufian habitation sites, the remains do not reflect the typical recurring post-discard damage resulting from continuous or repeating habitations in those sites. Hence the fauna is interpreted as the leftovers of punctuated, short-term events, rather than ‘ordinary’ Natufian household trash. Taking into account the special depositional context and site characteristics, we interpret the fauna as the intentionally-gathered and buried remains of simple funerary feasts. Elaborate mortuary behavior and symbolic role of food refuse were recently suggested at the contemporaneous cave of Hilazon Tachtit (Israel). The new data from Raqefet Cave probably reflect a somewhat different type of communal meals, adding to the diversity and complexity of pre-agricultural life-ways in the Levant.     

On some remains of dog (Canis familiaris) from the Mesolithic shell-middens of Muge,Portugal

The dog has a unique relationship with humans. This is demonstrated by the number of breeds that exist today and the important role that dogs play in human society. The archaeological record also shows that this relationship began long ago when groups of hunter–gatherers domesticated the wolf probably in several parts of the globe.     

Subsistence economics,family size,and the emergence of social complexity in hunter–gatherer systems in eastern North America

A consideration of ethnographic data, computational model results, and archaeological data suggest that changes in family-level economics coincident with subsistence intensification contributed to the emergence of social complexity among prehistoric hunter–gatherers in eastern North America by creating the conditions for a “rich get richer” scenario. Ethnographic data are used to construct a general computational model representing key person- and family-level behaviors, constraints, and decisions affecting the size and composition of hunter–gatherer families. Results from model experiments suggest that lowering the age at which children make a significant contribution to subsistence (e.g., through the broadening of the diet to include the kinds of mass-harvested, “low quality” foods that were increasingly exploited during the Archaic and Woodland periods) relaxes constraints on family size and makes large, polygynous families economically viable. Positive feedbacks between the productive and reproductive potentials of larger families produce right-tailed distributions of family size and “wealth” when the productive age of children is low and polygyny is incentivized. Size data from over 800 prehistoric residential structures suggest right-tailed distributions of family size were present during the Late Archaic through Middle Woodland periods. These distributions would have provided variability in family-based status that permitted the emergence of hereditary social distinctions.     

The role of canids in ritual and domestic contexts: new ancient DNA insights from complex hunter–gatherer sites in prehistoric Central California

This study explores the interrelationship between the genus Canis and hunter–gatherers through a case study of prehistoric Native Americans in the San Francisco Bay-Sacramento Delta area. A distinctive aspect of the region's prehistoric record is the interment of canids, variously classified as coyotes, dogs, and wolves. Since these species are difficult to distinguish based solely on morphology, ancient DNA analysis was employed to distinguish species. The DNA study results, the first on canids from archaeological sites in California, are entirely represented by domesticated dogs (including both interments and disarticulated samples from midden deposits). These results, buttressed by stable isotope analyses, provide new insight into the complex interrelationship between humans and canids in both ritual and prosaic contexts, and reveal a more prominent role for dogs than previously envisioned.     

In a nutshell: the identification and archaeological application of experimentally defined correlates of Macrozamia seed processing

This paper describes the methods and results of ethnographically-based replicative seed processing experiments conducted on Australian Macrozamia moorei seeds. Archaeological evidence indicates that these seeds were consumed by Australian hunter–gatherers in both the Pleistocene and Holocene. The experiments identified three features indicative of human processing and tested the effect of different processing variables (striking position, indentor type, thermal modification and presence of outer flesh) on the frequency of these diagnostic criteria. The results demonstrate that it is possible to use the physical modifications on individual seed specimens to identify the anthropogenic fracture of seeds and specific methods used to process them. These criteria were used in the analysis of M. moorei seeds from mid-Holocene-aged archaeological sites in central Queensland, Australia. The results indicate that seeds with and without sarcotesta were processed using a wooden indentor via side striking techniques.     

Retention of hunter–gatherer economies among maritime foragers from Caleta Vitor,northern Chile,during the late Holocene: evidence from stable carbon and nitrogen isotopic analysis of skeletal remains

On the basis of stable carbon and nitrogen isotope analysis of human remains, this paper provides evidence for the retention of hunter–gatherer economies among coastal inhabitants in northern Chile during the late Holocene – at the same time that inland populations were adopting agricultural economies. Coastal diets from the Caleta Vitor region of the Atacama Desert were dominated by marine-based foods, predominantly from upper trophic levels. The focus on reliable marine food resources is interpreted as a risk minimisation strategy in this marginal arid environment. Although these coastal hunter–gatherers adopted other goods and traditions from agricultural populations, their participation in this larger interregional exchange network did not affect their basic subsistence economies.     

Dietary ecology of extant guanaco (Lama guanicoe) from Southern Patagonia: seasonal leaf browsing and its archaeological implications

The analysis of dietary traits of ungulates through tooth microwear and mesowear has been applied to archaeological sites to investigate seasonal changes in settlements by hunter–gatherers. In this paper we propose to test the hypothesis that tooth microwear (combined to mesowear) is able to indicate seasonality in the diet of extant ungulates in arid habitats (semi-deserts or steppe). The material analyzed comes from six faunal monospecific assemblages of guanaco (Lama guanicoe) resulting from a mass mortality event in winter 2000 near the Cardiel Lake in Southern Patagonia (Province of Santa Cruz, Argentina). Mesowear results indicate that the guanacos from the Cardiel Lake area are mixed feeders, and thus, have a diet that shifts seasonally. Moreover, microwear analysis supports the hypothesis that tooth microwear is able to indicate seasonality in the diet of extant guanaco in arid habitats. The pattern is clear for the winter sample and needs to be confirmed for a summer sample. Consequently, tooth microwear is proposed as a new potential proxy for detecting seasonal occupation in archaeological sites in Patagonia and other arid environments.     

Staple or famine food?: ethnographic and archaeological approaches to nut processing in East Asian prehistory

Recent archaeobotanical studies in East Asia show that the use of wild food plants, particularly nuts, was important for not only hunter–gatherers but also early farmers. For example, recent archaeobotanical work has identified large quantities of nut remains from early Chinese rice farming sites dating 5,000–4,500 BC. In Japan, which introduced rice farming from China around 1,000–500 BC, archaeobotanical data have shown continued exploitation of nuts even after the introduction of rice farming. Therefore, the first appearance of farming does not appear to have immediately impacted the subsistence system, although it may have changed cultural perceptions of food plants, eventually rice replacing nuts as a staple food. To explain the cultural implications of this shift in emphasis, it is necessary to investigate people’s routine subsistence activities with reference to available ethnographic information on non-mechanised plant processing. The ethnographic data provide insights into ancient nut processing, including possible methods, tools, choices of working locations and labour scales. Conceptual modelling based on ethnographic observations of the range of nut-processing practices will also aid interpretations from newly developed methods, such as starch residue analyses. The resulting archaeobotanical, archaeological and ethnographic picture may help to further explore past social organisation and social perceptions of plant foods.     

Craniometric evidence for South African Later Stone Age herders and hunter–gatherers being a single biological population

Later Stone Age (LSA) hunter–gatherers and herders co-existed in South Africa during the last 2000 years. In spite of being the focus of intensive research over the years, the biological status and origins of the herders are still unclear. Did they represent a genetically distinct immigrant population who remained separate from the indigenous hunter–gatherers, or where they indigenous hunter–gatherers who took up herding after contact with herders, probably in northern Botswana? Here, this issue is investigated using craniometric data collected on a large sample of individually dated human crania from coastal LSA context. Mahalanobis distances (D), calculated from the raw metric data, show that there was a small increase in inter-individual craniofacial variation after the introduction of herding at ca. 2000 BP. Here it is argued that this small increase in variation is neither consistent with a large-scale immigration of genetically distinct herders into South Africa, or the long-term co-existence of two genetically distinct populations. Two alternative explanations fit the data better: (1) herding entered South Africa via the small-scale immigration of genetically distinct herders; and (2) local hunter–gatherer populations adopted herding after coming in contact with herders in northern Botswana. While small-scale immigration would not have had a major influence on the local gene pool, it would have increased variation to some extent as immigrants mixed with local populations. If small-scale external gene flow was not a factor in the introduction of herding, secular issues related to the introduction of herding could explain the increased variation in post-2000 BP populations.     

Fremont Hunting and Resource Intensification in the Eastern Great Basin

Empirical tests of resource-intensification models argue for diminishing foraging efficiency among hunter–gatherers in California over the past 2000 years (Basgall, 1987,Research in Economic Anthropology9,21–52; Broughton, 1994aJournal of Archaeological Science21,501–514; 1994bJournal of Anthropological Anthropology13, 371–401). The evidence for this long-term trajectory consists of decreases in the abundance of large, high-ranked prey in archaeofaunal assemblages. This paper presents faunal data from Fremont structural sites in the eastern Great Basin and Northern Colorado Plateau as an additional empirical test of resource intensification patterns and compares them to trends in California and the American Southwest. The measure of resource efficiency used is the artiodactyl index (following Broughton, 1994ab), a tool derived from prey choice models of optimal foraging. Faunal data from Fremont structural sites argue that (1) foraging efficiency declined during the Fremont period, and (2) this decline was due to population growth.     

Hunter–gatherer foraging ranges, migrations, and travel in the middle Holocene Baikal region of Siberia: Insights from carbon and nitrogen stable isotope signatures

Foraging ranges, migrations, and travel among Middle Holocene hunter–gatherers in the Baikal region of Siberia are examined based on carbon and nitrogen stable isotope signatures obtained from 350 human and 203 faunal bone samples. The human materials represent Early Neolithic (8000–6800 cal BP), Late Neolithic (6000–5000 cal BP), and Early Bronze Age periods (∼5000–4000 cal BP) and come from the following four smaller areas of the broader region: the Angara and upper Lena valleys, Little Sea of Baikal’s northwest coast, and southwest Baikal. Forager diets from each area occupy their own distinct position within the stable isotope spectrum. This suggests that foraging ranges were not as large as expected given the distances involved and the lack of geographic obstacles between the micro-regions. All examined individuals followed a similar subsistence strategy: harvesting game and local fishes, and on Lake Baikal also the seal, and to a more limited extent, plant foods. Although well established in their home areas, exchange networks with the other micro-regions appear asymmetrical both in time and direction: more travel and contacts between some micro-regions and less between others. The Angara valley seems to be the only area with the possibility of a temporal change in the foraging strategy from more fishing during the Early Neolithic to more ungulate hunting during the Late Neolithic–Early Bronze Age. However, the shift in stable isotope values suggesting this change can be viewed also as evidence of climate change affecting primary productivity of the Baikal–Angara freshwater system.     

Human impact and landscape utilization from the Mesolithic to medieval time traced by high spatial resolution pollen analysis and numerical methods

Pollen analysis in relation to archaeological excavations has been carried out by the coast of central Norway to investigate for the first time long-term human impact on the vegetation in this region. A total of 297 samples from eleven archaeological sites and connected bogs/peat profiles reveal the vegetation development from the Mesolithic until today. Principal Component Analysis (PCA) is used to identify and elucidate the development through time and space, and the results of pollen diagrams from bogs are compared to the results of on-site pollen data. Human impact has transformed the vegetation to a varying degree in different time periods. A dense population connected to the shoreline is slightly visible as opening-up of the forest in the Mesolithic, whereas re-use of Mesolithic settlement sites for cultivation and grazing in the Late Neolithic and Early Bronze Age (from c. 2300 cal BC) is clearly documented by palaeobotany but weakly recorded in the archaeological record. Areas for settlement and cultivation are found from the Late Bronze and Iron Ages and pollen analysis contributes to a detailed picture of utilization of the landscape. The investigation shows the potential of combining archaeological and botanical data and analysing several small pollen sequences within an excavation area to reveal spatial patterns in vegetation development and human impact through time.     

Complex Hunter–Gatherers in Evolution and History: A North American Perspective

A review of recent research on complex hunter–gatherers in North America suggests that age-old tensions between evolutionary and historical epistemologies continue to cultivate progress in anthropological understanding of sociocultural variation. Coupled with criticism of the evolutionary status of ethnographic foragers, archaeological documentation of variation among hunter–gatherer societies of the ancient past makes it difficult to generalize about causal relationships among environment, subsistence economy, and sociopolitical organization. Explanations for emergent complexity on the Pacific Coast that privilege environmental triggers for economic change have been challenged by new paleoenvironmental findings, while hypotheses suggesting that economic changes were preceded by, indeed caused by, transformations of existing structures of social inequality have gained empirical support. In its emergent data on mound construction apart from significant subsistence change, the southeastern United States gives pause to materialist explanations for complexity, turning the focus on symbolic and structural dimensions of practice that cannot be understood apart from particular histories of group interaction and tradition. Taken together, recent research on complex hunter–gatherers in North America has not only expanded the empirical record of sociocultural formations once deemed anomalous and/or derivative of European contact but also has contributed to the ongoing process of clarifying concepts of cultural complexity and how this process ultimately restructures anthropological theory.     

Prey Choice During the South African Middle Stone Age: Avoiding Dangerous Prey or Maximising Returns?

Scrutinising prey choice allows the testing of hypotheses on whether the hunting capabilities of Middle Stone Age (MSA) people were as sophisticated as those of Later Stone Age hunter–gatherers. I apply an optimal foraging perspective to investigate whether MSA prey choice was constrained by the danger associated with hunting certain species. Here, I study the relative importance of elands, buffalo and suids. Eland was the most attractive prey to hunter–gatherers because it is large and docile. Buffalo and suids are more aggressive. When additional species to eland needed to be exploited, we would expect unsophisticated hunters to prefer the smaller suids over buffalo. If hunting prowess was sufficient to deal with both buffalo and suids, buffalo should be preferred. Due to their size, exploitation of buffalo would be more profitable than exploitation of suids. I show that, taking environmental circumstances into account, buffalo were preferred to suids, suggesting that MSA people were capable, sophisticated hunters.     

Hunter–gatherer movement patterns: Causes and constraints

The study of hunter–gatherer mobility patterns is of vital importance to our understanding of the paleolithic archeological record. Such patterns necessarily comprise many interacting locales, and it is at the landscape scale that we should attempt to understand the relationship between ethnographic and archeological data. This paper derives, quantifies and tests a series of basic predictions about the effects of group size, occupation duration and habitat quality on mobility strategies using a substantial ethnographic dataset. The results demonstrate that habitat quality is the best determinant of move distances among hunter–gatherers, but that occupation duration also has an effect among those foragers who rely principally on hunting. It is suggested that three roughly concentric zones, the limit of scatter, the foraging radius, and the logistic radius, are predicted by group size and occupation duration, habitat quality, and proportions of hunting and logistical mobility, respectively. The relevance of these conclusions to more generic ecological theory is discussed in the context of evolutionary forces acting on hunter–gatherer mobility in prehistory.     

Design and performance of microlith implemented projectiles during the Middle and the Late Epipaleolithic of the Levant: experimental and archaeological evidence

The study comprises an experimentally based investigation of interaction between temporal change in the morphology of microlithic tools and transformations in projectile technology during the Late Pleistocene in the Levant. Archery experiments with differently designed arrows fitted with various types of microliths representing subsequent Epipaleolithic cultures of the Levant allowed analyzing performance abilities of the arrows, identifying projectile damage types characteristic of particular hafting modes, detecting factors influencing the frequency of projectile damage and estimating the frequency of projectile damage expected to be found in archaeological samples. The data obtained through the experiments applied in the analysis of the archaeological microliths from Geometric Kebaran and Natufian sites in Israel indicate different approaches to the design of projectiles fitted with microliths characteristic for these cultures. The shift in design, associated with such important economic and social transformations as transition to sedentary settlements and a broad-spectrum economy, may reflect a demand for light, flexible and efficient projectile weapons requiring low time and labor investment for preparation and retooling. The use of such efficient weapons in conditions of growing population density and restricted areas available for Natufian hunter–gatherers can be considered as one of the factors that could have affected the subsequent transition to food production that took place in the early Holocene.     

An ethnopalynological test of task-specific area analysis: Bay View Stable,Cataumet, Massachusetts

Palynologists seeking evidence of patterns in human plant use among the pollen spectra of archaeological site floors operate on the assumption that the pollen of economic plants is deposited at the locations of undertakings involving these plants in quantities significantly exceeding the amounts of the same pollen types in the background pollen component. This assumption has never been questioned in the literature, even though it has not been tested. Researchers are, however, uncertain about the extent to which floor deposits of economic pollen are affected by later human activities. Pollen profiles from three functionally distinct bays in the cellar of a New England livestock barn that was actively used for at least 40 years were analyzed to examine economic pollen deposition and dispersal. The data from this test indicate that the pollen of economic plants is deposited in distinctive quantities where the plants were used and that these pollen deposits are not significantly diffused by subsequent human activity. The data also suggest that pollen concentrations per unit of matrix will assist in defining active surfaces within archaeological floor zones.
