Finding a Place for Networks in Archaeology Abstract Formal network analyses have a long history in archaeology but have recently seen a rapid florescence. Network models drawing on approaches from graph theory, social network analysis, and complexity science have been used to address a broad array of questions about the relationships among network structure, positions, and the attributes and outcomes for individuals and larger groups at a range of social scales. Current archaeological network research is both methodologically and theoretically diverse, but there are still many daunting challenges ahead for the formal exploration of social networks using archaeological data. If we can face these challenges, archaeologists are well positioned to contribute to long-standing debates in the broader sphere of network research on the nature of network theory, the relationships between networks and culture, and dynamics of social networks over the long term.

Extracting Insights from Prehistoric Andean Metallurgy: Political Organization, Interregional Connections, and Ritual Meanings Abstract Metal production in the prehistoric Andes entailed an array of political, economic, and ritual relationships that are increasingly the focus of archaeological investigation. One theme directing recent research is the link between metallurgy and political organization, including the origins of metal production, its relationship to sociopolitical complexity, and how shifts in the organization of metal production reflect and shape diachronic political transformations. A second theme is the use of metals to identify and interrogate interregional connections. Patterns in the circulation of different alloys and metal isotopes, as well as the transfer of technology, provide insight into the shifting constellations of economic and political connections maintained by prehispanic Andean populations. A final theme is ritual and meaning in Andean metallurgy, where I explore how the stages of mining, extractive metallurgy, and the production of metal objects added multivalent layers of meaning and value to metal artifacts. Operating in distinct ways across time and space, metallurgy in the ancient Andes could stimulate political complexity, drive geopolitical expansion and the integration of new subject populations, differentiate individuals and groups, connect people to one another and to the landscape, and harness the power of the numinous.

The Innovation and Adoption of Iron in the Ancient Near East Abstract This review synthesizes field research, textual analysis, and archaeometric data to evaluate different explanations for the spread of iron in the ancient Near East. Current evidence supports an Anatolian origin for extractive iron metallurgy on a limited scale sometime in the early 2nd millennium BC. However, the first major expansion of iron, both in Anatolia and across the wider Near East, occurred in the late second and early first millennium BC. Explanations that place iron adoption within its broader social context are favored over those that consider material or geological properties in isolation. A recurring theme is the importance of comparative analysis, both geographically and between the iron and bronze economies, to explore how social, political, and economic conditions affected adoption patterns.

The Archaeology of the Early Tibetan Plateau: New Research on the Initial Peopling through the Early Bronze Age Abstract Since the last systematic review of Tibetan archaeology in 2004 published in Journal of World Prehistory (Aldenderfer and Zhang 2004), a revival of archaeological research on the plateau has begun to reshape our understanding of key issues such as when the plateau was first permanently occupied by humans, and when and how Tibetans first adopted the farming and pastoral systems that characterize the plateau today. Understanding who the first Tibetans were, and how they adapted to this high-altitude environment, both genetically and culturally, have been central themes of recent research on the plateau. We review these developments and place them into a wider regional framework with a focus on the better-known eastern Tibetan Plateau.

Evaluating Social Complexity and Inequality in the Balkans Between 6500 and 4200 BC Abstract The subject of this paper is the social structure and sociocultural evolution of Balkan Neolithic and Eneolithic societies between 6500 and 4200 BC. I draw on archaeological evidence from three major regions of the Balkans related to demography, settlement, economy, warfare, and differences in status and wealth between individuals and groups to evaluate the degree and kind of social complexity and inequality. The trend in these data is of increase in social complexity and inequality over two millennia following the introduction of agriculture to the Balkans, as the simple and small hamlets of the late seventh and early sixth millennia transformed into large villages and tell sites of the late sixth and fifth millennia, in parallel with the development of copper metallurgy and regional exchange networks. There is no evidence of social stratification or the formation of complex systems of regional integration such as (proto)states or urban centers. The Balkan communities of this period were essentially village communities with social inequalities, when present, limited to differences in prestige and potentially rank.

The Rise of Pastoralism in the Ancient Near East Abstract In this paper, we present a history of pastoralism in the ancient Near East from the Neolithic through the Bronze Age. We describe the accretional development of pastoral technologies over eight millennia, including the productive breeding of domestic sheep, goats, and cattle in the early Neolithic and the subsequent domestication of animals used primarily for labor—donkeys, horses, and finally camels—as well as the first appearance of husbandry strategies such as penning, foddering, pasturing, young male culling, and dairy production. Despite frequent references in the literature to prehistoric pastoral nomads, pastoralism in Southwest Asia was strongly associated with sedentary communities that practiced intensive plant cultivation and was largely local in nature. There is very little evidence in prehistoric and early historic Southwest Asia to support the notion of a “dimorphic society” characterized by separate and specialized agriculturists and mobile pastoralists. Although mobile herders were present in the steppe regions of Syria by the early second millennium BC, mobile pastoralism was the exception rather than the rule at that time; its “identification” in the archaeological record frequently derives from the application of anachronistic ethnographic analogy. We conclude that pastoralism was a diverse, flexible, and dynamic adaptation in the ancient Near East and call for a reinvigorated and empirically based archaeology of pastoralism in Southwest Asia.

A History of Cacao in West Mexico: Implications for Mesoamerica and U.S. Southwest Connections Abstract Cacao economies in far western Mexico developed between AD 850/900 and 1350+ along with the adoption of a political–religious complex centered on the solar deity Xochipilli as the Aztatlán culture became integrated into expanding political, economic, and information networks of highland and southern Mesoamerica. The Xochipilli complex significantly transformed societies in the Aztatlán core zone of coastal Nayarit and Sinaloa and parts of Jalisco, Durango, Zacatecas, and Michoacán. West Mexican cacao was acquired in the U.S. Southwest by Chaco Canyon elites in New Mexico through macroregional prestige goods economies as Ancestral Pueblo societies became integrated into the Postclassic Mesoamerican world.

Early Urbanism in Northern Mesopotamia Abstract Cities generate challenges as well as confer advantages on their inhabitants. Recent excavations and surveys in northern Mesopotamia have revealed extensive settlements with diverse populations, institutions, extended hinterlands, and mass production by the early fourth millennium BC, comparable to well-known evidence for cities in their traditional homeland of southern Iraq. However, early northern Mesopotamian cities incorporated low-density zones and flexible uses of space not yet identified in southern Mesopotamia. Evidence for violent conflict in northern Mesopotamian cities also raises questions about urban sustainability; cities succeeded despite new sources of social stress.

Archaeology for Sustainable Agriculture Abstract How will archaeology contribute to agricultural sustainability? To address that question, this overview reflects on the diverse and complementary ways that archaeology has advanced our understanding of sustainable agriculture. Here, I assess recent archaeological research through the lens of the five principles of sustainable agriculture used by the Food and Agriculture Organization of the United Nations. These principles—efficiency, conservation, rural livelihoods, resilience, and governance—highlight the social and environmental dimensions of agricultural sustainability. By drawing on case studies from around the world, I show how archaeology is uniquely situated to examine the interactions of these social and environmental dimensions over long periods of time. Archaeology’s strongest conceptual contributions to sustainable agriculture are (1) its capacity to demonstrate that sustainability is historically contingent and (2) its attention to outcomes. If transformed into meaningful action, these contributions have the potential to advance modern agricultural sustainability and environmental justice initiatives. This overview is an invitation to clarify a plan for future research and outreach. It is an invitation to imagine what an archaeology for sustainable agriculture will look like and what it will accomplish.

The Inertia of Old Ideas: A Historical Overview of Theoretical and Methodological Challenges in the Study of Classic Maya Political Organization Abstract While it is tempting to assume that empirical advancements inexorably lead to incremental improvement in our understanding of the past, the impact of ideas—even empirically untenable positions—often impede disciplinary progress. This paper examines the intellectual history of changing views of Classic Maya political organization, from the formulation of the “traditional synthesis” to contemporary debates. Although the traditional synthesis did not stand up to empirical evaluation, elements of the model continued to have substantive impact into the 21st century. This historical overview is part of a broader critique of ways we create and evaluate theories about the ancestral Maya past. With a century of archaeological research and the maturation of epigraphic research providing a rich empirical foundation, the successes or failures of the next generation of research will be governed by advancements in theory building and long overdue methodological reforms.
