Activity across space on the threshold of complexity: Microdebris analysis at Late Chalcolithic 1 Tell Surezha, Iraq

The study of archaeological microdebris—small pieces of debris preserved in surface matrices—can offer insight into the distribution of past activity across space. This study provides a methodological test case for microdebris analysis. It contributes to understanding of late prehistoric economy and society in Mesopotamia by providing fine-grained spatial data on the organization of activity at one village site on the Erbil Plain, and offers a spatial perspective on emergent social complexity in the Late Chalcolithic in North Mesopotamia.An analysis of microdebris from the 5th millennium occupation of Tell Surezha, Iraq, suggests that domestic spaces were centers of debris-producing activities, with a high degree of multifunctionality in their use. Courtyards in particular appear to have been centers of both production and consumption. By contrast, certain nondomestic spaces were characterized by very low levels of debris-producing activity and apparent limits on access. These data support an interpretation of the period as one in which economic activity was centered on houses and organized at the household level, even as nondomestic institutions were beginning to exert control over activity outside the home.

Paddy rice, aggregation, and the development of Mumun social organization in Ulsan, southeastern Korea

Previous research has reported that Mumun settlements (ca. 1500–300 BCE) in southeastern Korea consisted of multiple house clusters that were basal social units. This study evaluates this claim by inspecting intra-settlement dwelling distribution in sites with more than 40 pithouses. Ripley's K-function and the density-based spatial clustering of applications with noise (DBSCAN) method were implemented to identify pithouse clusters at different spatial scales. Our examination shows that the settlements contained small, primary clusters of ca. 10–40 people, which merged into larger, secondary clusters of fewer than 60 people. Large settlements consisted of multiple secondary clusters. We infer that people aggregated to meet the labor demand of paddy rice cultivation, while simultaneously managing the scalar stress by dividing communities into smaller subgroups. This study suggests that emergent social complexity during the Mumun period relied on factional competition and cooperation and was dependent on the effective integration of discrete social units.

Environment, climate and people: Exploring human responses to climate change

In 2004, the Journal of Anthropological Archaeology published Julie Field’s “Environmental and climatic considerations: a hypothesis for conflict and the emergence of social complexity in Fijian prehistory”, where she combined climate and environmental data to investigate the relationship between social patterns of change in the context of variability. Field tackled a complex issue: how societies respond to climate and environmental change that could cause unpredictable impacts on subsistence and settlement systems. Much progress has been made towards the understanding of human adaptations or responses to climate change since that paper was published. Here I reflect on the issues put forth by Field and consider how archaeology can engage with other interdisciplinary sciences and contribute to the understanding of human responses to environmental change. Two topics are emphasized: climate and environmental change, and social behavior in the context of that change. When attempting to identify how climate change affects a society, it is necessary to downscale climate to the specific location in consideration (space) during the time-period during which the relevant society lived (time) and in the context of their past experiences of climate (traditional knowledge). We face an unprecedented climate crisis and archaeology can contribute to the identification of solutions.

Textile production and craft specialisation at Tianluoshan in the lower Yangzi Valley

Early craft specialisation provides insights into the emergence of social complexity. Textile production also offers a lens through which specialisation can be recognised. Here, the authors present a detailed contextual and technological analysis of a large assemblage of textile-production tools from Tianluoshan, a waterlogged Middle Neolithic site in the Yangzi Valley, China. Using thechaîne opératoireapproach, tools are identified, their roles in the production process explained and their significance explored. The results trace the production of textiles from spinning through loom weaving to fabric construction with needles. The use of a variety of fibre-based plants is suggested and tentative evidence for the early use of ground looms explored.

Agriculture, the Environment, and Social Complexity From the Early to Late Yangshao Periods (5000–3000 BC): Insights From Macro-Botanical Remains in North-Central China

In northern China, the Yangshao cultural period (5000–3000 BC) was a critical timespan in the establishment of agricultural economies and the emergence of social complexity. We present the results of archeobotanical analysis from 58 soil samples collected from 12 recently investigated sites located in the Luoyang Basin, and recovered 5290 carbonized plant remains from 9 sites dating to the Late Yangshao period. We compared our novel dataset with previous archeobotanical date, compiling a total of 196 samples from 58 sites in central and western Henan Province. During the Early Yangshao period (5000–4200 BC), a nascent, extensive agricultural economy based primarily on broomcorn millet, with lesser foxtail millet and rice, was developing in small settlements (<0.2 km2) in the loess tablelands and valleys of western Henan province. However, the population pressure—rather than environmental degradation—drove the “foxtail millet-broomcorn millet substitution” during the Middle Yangshao period (4200–3500BC). The intensive agriculture based mainly on foxtail millet facilitated the development of social complexity in the region, as demonstrated by the emergence of size-graded agricultural settlements of medium (0.2–0.6 km2) and large (> 0.6 km2) scale. Notably, millets tend to be less ubiquitous in these larger settlements compared to smaller ones, with differences in millet ubiquity between sites increasing over time. The local surface hydrology influenced by paleoclimatic changes prompted the spread of agriculture from higher loess tablelands and valleys during the early Yangshao period into more marginal loess tablelands and plains by the Middle and Late Yangshao periods. Rice cultivation is concentrated in valley areas and appears to have been closely tied to environments with better hydrothermal conditions. Our research shows that climatic conditions during the Holocene fostered the development of agriculture during the Yangshao Culture period and that the distribution of settlements throughout this time was influenced by highly localized geomorphologic environments delimiting the distribution of crops. The rise of agriculture promoted the formation of complex and stratified economies in the Yangshao Culture period and it was the intensification and elaboration of these new economic and social systems that led to later transformation in agricultural structures and settlement sizes.

Mediterranean polyculture revisited: Olive, grape and subsistence strategies at Palaikastro, East Crete, between the Late Neolithic and Late Bronze Age

This paper examines agriculture, farming and dietary resources in east Crete, and re-evaluates the role of grape and olive in its prehistoric economy, these being key in debates on the emergence of social complexity. To do so bioarchaeological, paleoenvironmental and landscape survey data from the Bronze Age town at Palaikastro and its territory are combined. The results indicate a highly compartmentalised landscape, including intensive crop cultivation and extensive animal herding with careful monitoring to maintain productivity. A heightened specialisation in ovicaprine management at Palaikastro and east Crete seems to be delineated. Marine resources were regularly exploited from easily accessible coastal areas. Other activities included viticulture since the Early Minoan period, with the possible involvement of several houses in wine-making. A final important activity in the area was large-scale olive tree management since the Final Neolithic period and through to the Late Bronze Age, that seems to be entangled with ovicaprine herding and grazing. Thus, the demand for olive oil production does not seem to have been the driving force behind the intensification of the tree management, at least initially, but a corollary of its use in other aspects of the local economy.

Of Watery Rocks and Slumbering Crocs: Reassessing Middle Preclassic Occupation at Altun Ha and Lamanai, Belize

ABSTRACT Excavations in northeastern Belize have generated one of the more detailed regional databases of Middle Preclassic (1000–350 b.c.) settlement in the Maya Lowlands, providing the basis for developmental models of later Maya civilization. Modest Classic period architecture permitted extensive exposures of early occupations at several sites, but contemporaneous settlements at large, later centers remain poorly understood, despite the insights they may offer into emergent social complexity and political hierarchy. We review extant and unpublished data from Lamanai and Altun Ha, two large centers in northeastern Belize during Classic times, to compare aspects of Middle Preclassic settlement, architecture, and burial practices and to evaluate how this evidence relates to existing models of early Maya community development. Comparisons between these sites and among other Middle Preclassic settlements beyond northeastern Belize suggest a more nuanced approach to understanding developing social complexity in the Maya Lowlands, which acknowledges regional similarities and variability, is warranted.

Maize and dietary change in early Peruvian civilization: Isotopic evidence from the Late Preceramic Period/Initial Period site of La Galgada, Peru

The Late Preceramic Period (3000–1700 BCE) and Initial Period (1700–800 BCE) in Peru was a time of emergent social complexity as illustrated by the construction of ceremonial architecture and permanent settlements. A long-standing debate centers on the nature of the subsistence economies that supported this incipient complexity. Though some scholars consider maize to have been an agricultural staple at this time, a growing body of archaeological research indicates that the use of maize spread irregularly throughout Peru and did not become a dietary staple until sometime after c. 800 cal BCE. Using stable isotope analysis (δ13C and δ15N) of human bone and dentine, together with radiocarbon dating, this study estimates dietary composition, as well as changing subsistence strategies among 32 individuals interred within the ceremonial center of La Galgada (2300–1300 cal BCE). Our data suggests that maize was not a dietary staple in either the Late Preceramic or the Initial (1700–800 cal BCE) Period occupations at La Galgada. Instead the modeled diet (SIAR Mixing Model) suggests a continued reliance on locally available food sources (i.e. primarily C3, legumes and grazing fauna). This finding combined with archaeological evidence indicates that diet remained relatively similar during the site’s occupation. Three radiocarbon dates generated for this study also indicate the re-use of La Galgada as a cemetery during the Late Intermediate Period (LIP) (1150–1450 cal CE). Diet during the LIP exhibits a significant change, with a decrease in the proportion of C3 and legumes and an increase in the proportion of meat. This study highlights the utility of mixing models to reconstruct past human diet, allowing for a more comprehensive understanding of potential differences in the proportions of food types over time.

Fodder, pasture, and the development of complex society in the Chalcolithic: isotopic perspectives on animal husbandry at Marj Rabba

The emergence of social complexity in the Southern Levant during the Chalcolithic (c. 4500–3600 cal. BC) was intimately tied to intensification in animal management. For the first time, secondary products such as milk and wool were intensively exploited, supplying communities with increasingly diverse foodstuffs and raw materials for craft production and exchange, but the precise herding practices underlying these new production strategies are unknown. Here, we explore the role of multi-species livestock pasturing through carbon and nitrogen isotopic analysis of animal bones from Marj Rabba (Har Hasha’avi, West) in the Lower Galilee (ca. 4600–4200 cal. BC). Isotopic results suggest different pasturing/foddering of sheep compared with goats. Cattle were largely pastured locally, but high δ13C values in some animals indicate access to the Jordan River Valley (the Ghor in Arabic), where major Chalcolithic settlements were situated. This may indicate some cattle were moved along regional Chalcolithic exchange networks established for other prestige objects, such as copper. Finally, we provide evidence for moderate 15N enrichment in pigs relative to herbivorous livestock indicates. Possible interpretations include consumption of nuts (esp. acorns), household refuse containing animal protein, and/or fattening pigs on grain. Although an interpretation that requires further exploration, grain foddering of pigs would complement the zooarchaeological data for early slaughter, which suggests intensive meat production at Marj Rabba. It might also help explain why pig husbandry, as a drain on grain stockpiles, was gradually abandoned during the Bronze Age. Taken together, the isotopic and zooarchaeological data indicate an economy in transition from a non-specialized, household-based Neolithic economy to one in which the production of agrarian wealth, including animal secondary products, was beginning to emerge.

Evaluating the Gridded Agricultural Field Model in Chaco Canyon, New Mexico, Using Geophysical Remote Sensing

Recent geophysical remote sensing, including ground-penetrating radar and magnetometry, has been used to investigate three areas within Chaco Canyon, New Mexico, predicted to contain prehispanic agricultural fields. These localities include a well-known but enigmatic area of large grid patterns near the Chetro Ketl great house, which are visible from the air but not at ground level. The gridded area has been interpreted by many researchers as an agricultural field system, and this perspective has in turn been utilized to model agricultural land use throughout the canyon, particularly intensification associated with emergent social complexity. The geophysical surveys revealed evidence of buried features at all three study areas, but the patterns expressed by these features do not clearly conform to the pattern predicted in the gridded agricultural field model. We argue that the surficial grid pattern seen at the Chetro Ketl field is an unusual example of land modification in the canyon and thus unlikely to represent typical Chacoan agricultural field systems. Instead, canyon residents employed a diverse range of agricultural techniques suited to the variable and patchy nature of canyon hydrology and soils.

Walrusing, whaling and the origins of the Old Bering Sea culture

ABSTRACTFor a century, archaeologists have puzzled over the enigma of successful whaling unfolding with no predecessors prior to the last two millennia. The emergence of social complexity is linked with the appearance of the Old Bering Sea (OBS) aesthetic engraved on walrus ivory implements found in sites with large cemeteries and thick middens. Significantly, many OBS sites co-occur with major haulout locations for Pacific walrus, whose procurement engendered relationships that, along with seafaring or hunting technology, were the pivotal drivers that fostered whaling. Our revision of extant 14C assays to correct for marine carbon produces a younger ‘Low’ chronology placing the OBS florescence between AD 650–1250, with its earliest phase Okvik and allied Ipiutak communities from AD 300 to 600. The lithic technology of OBS is distinctive in its notched bifaces with affinities to 3000-year-old Chukchi Archaic assemblages. Later influences on OBS development include Ipiutak lithic technology and suggest migration, and either adversarial, or trading relationships with Alaska. The acquisition of rare commodities (driftwood, iron and obsidian) contributed to differential success and resulted in inequality recorded in burials.

Investigating prehistoric diet and lifeways of early farmers in central northern Spain (3000–1500 CAL BC) using stable isotope techniques

This work focuses on reconstructing past diets and animal management during Prehistory in Central Northern Spain, spanning the NE area of the Old Castilian Plateau to the Cantabrian coast, from c. 3000–1500 BCE. During this time, early farming communities made changes in their models of production and social reproduction that crystallised in the emergence of social complexity. To investigate these changes, we reconstructed the past diet of these early farming populations by using stable isotope analysis (δ13C, δ15N, δ34S) of human and animal remains from the recently excavated sites of Abrigo de la Castanera in Cantabria and Arroyal I, El Hornazo, Fuente Celada and Ferrocarril-La Dehesa in Burgos. The human remains derived from a range of burial contexts including pit graves, megalithic monuments and burial caves. To provide initial insights into animal management during this timeframe, associated faunal remains were also studied as a baseline. In total, 52 samples were analysed, including 17 human burials and 35 animal specimens (cattle, sheep, pig, red deer and dog). Results show that humans in these sites consumed relatively similar diets, comprising of a predominantly C3 diet including animal protein. Animal management patterns indicate a wider use of the landscape for herbivore grazing. The differing diets of dogs at El Hornazo provide insights into the relationship that they had with humans and tentatively suggests differences in the diet of working animals versus household pets. The δ34S values of two individuals from Arroyal I indicate that they came from different regions, implying a level of inland mobility during the Chalcolithic.

The impact of population dynamics on social complexity in Neolithic Orkney

Johnson and Earle (2000) argue that population growth and technological change are the primary causes of increasing social complexity in prehistory. This paper investigates whether there is evidence to support this theory in the archaeological remains of Neolithic Orkney. It begins with a brief overview of the relevant archaeological developments in Orkney that suggest increasing social complexity following the introduction of agricultural technology early in the 4th millennium BC. It then summarizes the Johnson and Earle argument linking emergent social complexity to rising population. An estimate of population dynamics for the period using recent improvements in the “dates as data” method follows including a suggestion for a further refinement in the technique. The paper concludes that there is good evidence to support the assertion that increasing social complexity is correlated with rising population in Neolithic Orkney.

Early metal use and crematory practices in the American Southeast

Long-distance exchange of copper objects during the Archaic Period (ca. 8000-3000 cal B.P.) is a bellwether of emergent social complexity in the Eastern Woodlands. Originating from the Great Lakes, the Canadian Maritimes, and the Appalachian Mountains, Archaic-age copper is found in significant amounts as far south as Tennessee and in isolated pockets at major trade centers in Louisiana but is absent from most of the southeastern United States. Here we report the discovery of a copper band found with the cremated remains of at least seven individuals buried in the direct center of a Late Archaic shell ring located in coastal Georgia. Late Archaic shell rings are massive circular middens thought to be constructed, in part, during large-scale ritual gatherings and feasting events. The exotic copper and cremated remains are unique in coastal South Carolina and Georgia where Archaic-age cremations are conspicuously absent and no other Archaic copper objects have been reported. Elemental data produced through laser ablation inductively coupled plasma mass spectrometry shows the copper originated from the Great Lakes, effectively extending Archaic copper exchange almost 1,000 km beyond its traditional boundaries. Similarities in mortuary practices and the presence of copper originating from the Great Lakes reveal the presence of long-distance exchange relations spanning vast portions of the eastern United States and suggest an unexpected level of societal complexity at shell ring localities. These findings are consistent with the hypothesis that elite actors solidified their positions through ritual gatherings and the long-distance exchange of exotic objects during the Archaic.

Cognitive mechanisms for human flocking dynamics

Low-level “adaptive” and higher-level “sophisticated” human reasoning processes have been proposed to play opposing roles in the emergence of unpredictable collective behaviors such as crowd panics, traffic jams, and market bubbles. While adaptive processes are widely recognized drivers of emergent social complexity, complementary theories of sophistication predict that incentives, education, and other inducements to rationality will suppress it. We show in a series of multiplayer laboratory experiments that, rather than suppressing complex social dynamics, sophisticated reasoning processes can drive them. Our experiments elicit an endogenous collective behavior and show that it is driven by the human ability to recursively anticipate the reasoning of others. We identify this behavior, “sophisticated flocking”, across three games, the Beauty Contest and the “Mod Game” and “Runway Game”. In supporting our argument, we also present evidence for mental models and social norms constraining how players express their higher-level reasoning abilities. By implicating sophisticated recursive reasoning in the kind of complex dynamic that it has been predicted to suppress, we support interdisciplinary perspectives that emergent complexity is typical of even the most intelligent populations and carefully designed social systems.

Toward a Definition of Minoan Agro-Pastoral Landscapes: Results of the Survey at Palaikastro (Crete)

Agricultural production and the palatial redistribution of staples have played a key role in the debate concerning the emergence of social complexity in Minoan Crete. However, much of the focus has fallen on major settlements where such products were consumed, rather than on the landscape where agricultural surplus was produced. While there is no shortage of landscape surveys on Crete, their emphasis has typically been on the distribution of rural settlements instead of on identifying landscape structures and arrangements—such as terraces, enclosures, and field systems—that might provide data about a territory's economic focus. A key aim of the new survey at Palaikastro has been to address this bias. By combining extensive archaeological survey with differential GPS (DGPS) measurements, high-resolution aerial photography, and microrelief generation and analysis, the project has identified hundreds of structures, forming an almost continuous fossilized landscape and providing important clues on landscape management practices. The results highlight the importance of pastoral practices, to which a large part of the landscape was dedicated. Agricultural arrangements were also documented in the form of terraced areas adapted for dryland agriculture and reflecting concerns for soil retention. We argue that a highly structured landscape, indicative of pressures in land use, was established during the Middle and Late Minoan periods across Palaikastro's territory.

Amber, beads and social interaction in the Late Prehistory of the Iberian Peninsula: an update

The identification of archaeological amber has been used in Iberian prehistory to evidence long-distance exchanges and engage Iberia in networks that connect western Europe with central and northern Europe, the emergence of social complexity, and the consolidation of trade networks. However, until now, no comprehensive analytical study of the Iberian amber has been produced to support any of the interpretive models currently in use. This paper approaches the analysis of Iberian Peninsula amber artefacts by considering their provenance (based on FTIR characterization), chronology, and spatial relationship with other exotica. Our work increases the number of analyzed artefacts to 156 (24%), out of the c. 647 currently known for the Iberian Peninsula. Based on these new data and a review of Murillo-Barroso and Martinon-Torres (2012), this overview outlines amber consumption patterns from the 6th to 2nd millennia BCE and demonstrates long-distance amber exchange connecting Iberia with the Mediterranean region from the Neolithic period onwards.

Refining the Maritime Foundations of Andean Civilization: How Plant Fiber Technology Drove Social Complexity During the Preceramic Period

Moseley’s (1975) Maritime Foundations of Andean Civilization hypothesis challenges, in one of humanity’s few pristine hearths of civilization, the axiom that agriculture is necessary for the rise of complex societies. We revisit that hypothesis by setting new findings from La Yerba II (7571–6674 Cal bp) and III (6485–5893 Cal bp), Río Ica estuary, alongside the wider archaeological record for the end of the Middle Preceramic Period on the Peruvian coast. The La Yerba record evinces increasing population, sedentism, and “Broad Spectrum Revolution” features, including early horticulture of Phaseolus and Canavalia beans. Yet unlike further north, these changes failed to presage the florescence of monumental civilization during the subsequent Late Preceramic Period. Instead, the south coast saw a profound “archaeological silence.” These contrasting trajectories had little to do with any relative differences in marine resources, but rather to restrictions on the terrestrial resources that determined a society’s capacity to intensify exploitation of those marine resources. We explain this apparent miscarriage of the Maritime Foundations of Andean Civilization (MFAC) hypothesis on the south coast of Peru by proposing more explicit links than hitherto, between the detailed technological aspects of marine exploitation using plant fibers to make fishing nets and the emergence of social complexity on the coast of Peru. Rather than because of any significant advantages in quality, it was the potential for increased quantities of production, inherent in the shift from gathered wild Asclepias bast fibers to cultivated cotton, that inadvertently precipitated revolutionary social change. Thereby refined, the MFAC hypothesis duly emerges more persuasive than ever.

Biological Kinship, Postmarital Residence and the Emergence of Cemetery Formalisation at Prehistoric Marathon

AbstractThis paper examines the role of kinship and postmarital residence in the emergence of organised cemeteries during the transition from the Final Neolithic to the Early Bronze Age at Marathon, Attica. Focusing on the cemetery of Tsepi, we performed intra‐cemetery biodistance analysis to test whether biological relatedness structured spatial organisation of tombs, and whether postmarital residence was matrilocal or patrilocal. Dental metric, dental morphological and cranial non‐metric data were collected from 293 individuals and subjected to multivariate analysis (principal component analysis, Euclidean distance ordination via multidimensional scaling), binomial probability calculations, Ripley's K analysis and determinant ratio analysis. Results indicated phenotypic similarity among some tomb co‐interments; however, outliers suggested that within‐tomb burial depended on a variety of factors that could include affinal, fictive or practical kinship. There was strong evidence for phenotypic patterning by tomb row, indicating that cemetery structure at Tsepi was organised according to biological lineages. This was especially evident for females. Male phenotypic variation was higher than that of females, though not significantly so. The results of intra‐cemetery biodistance analysis at Tsepi reveal a complex mortuary programme that emphasised biological kinship within an exogamous and likely matrilocal system of mate exchange. When considered in light of ethnographic evidence, the practice of male exogamy may correlate with the coastal location of the community and the maritime activities that structured the economy during the emergence of social complexity in the region. This paper illustrates the potential of biodistance analyses for elucidating aspects of social life in the Aegean. Copyright © 2017 John Wiley & Sons, Ltd.
