Cultural transmission, copying errors, and the generation of variation in material culture and the archaeological record

Archaeologists are adept at analyzing variation in artifacts. The discipline has well established and tested methods to track change through time and to evaluate the function of artifacts that depend upon measures of variation in the archaeological record. Although a critical concept, the means by which variation in material culture is generated is not well understood. This paper explores one source of variation, copying errors, and systematically examines how cultural transmission processes act to amplify, reduce, or maintain such variation. Using simple models, we generate expected distributions for the amount of variation that occurs through time under varying circumstances. This variation is caused by small errors that are transmitted from one person to another in the propagation and replication of cultural traits. These baseline values provide useful null models for explaining variation in prehistoric assemblages of artifacts. We use measurements of projectile points from Owens Valley and Woodland ceramics from Illinois to demonstrate the value of this approach.     

Representation and Recursion in the Archaeological Record

Living humans are unique among the animal kingdom with respect to their ability to externalize mental representations outside the brain through a variety of media and in a recursive or creative manner (i.e., generating a potentially infinite array of combinations). Earlier humans evolved two specialized organs—the hand and the vocal tract—as primary instruments for externalizing artificial or semantic representations. These organs and the externalized representations may have co-evolved with the Homo brain. The archaeological record yields examples of simple representations by 1.6 mya. More complex, hierarchical, and recursive forms are evident by roughly 0.25 mya. Complex and highly recursive representations in a wide range of media (including representations of representations in the form of visual art) emerge after 0.1 mya among anatomically modern humans.     

The Neolithic Macro-(R)evolution: Macroevolutionary Theory and the Study of Culture Change

The macroevolutionary approach in archaeology represents the most recent example in a long tradition of applying principles of biological evolution to the study of culture change. Archaeologists working within this paradigm see macroevolutionary theory as an effective response to the shortcomings of neo-Darwinian biological evolution for studying cultural evolution. Rather than operating at the level of individual traits, macroevolutionary archaeologists emphasize the role of hierarchical processes in culture change. While neo-Darwinian archaeologists disavow any element of human intent in culture change, to macroevolutionary archaeologists human agency is a key component of cultural evolution that allows cultures to respond to pressures more quickly and with greater degree of flexibility and directedness than found in biological evolution. Major culture change, when it happens, is likely to be rapid, even revolutionary, with periods of rapid change separated by periods of relative stasis of actively maintained stability. The emergence of Neolithic cultures has long been recognized as one of two periods of major revolutionary culture change in human prehistory. Here I examine the record for the Near East, tracing the empirical record for the origin of agriculture in this region, as well as other demographic, social, and ideological components of Neolithic emergence. While the empirical record from the Near East subscribes in a general way to basic principles of macroevolutionary theory, cultural evolution cannot be understood through appeal to principles of biological evolution alone, whether based in macroevolutionary theory or neo-Darwinianism. Instead, the key role of human agency in culture change distinguishes cultural evolution from biological evolution and requires a more pluralistic and less doctrinaire appeal to multiple models of change based in both the biological and social sciences.     

A Risk Assessment for Cultural Heritage in Southern Iraq: Framing Drivers,Threats and Actions Affecting Archaeological Sites

ABSTRACT

This paper proposes a classification of the risks threatening archaeological sites in southern Iraq and suggests some possible remediation to better preserve them. This has been possible thanks to a research methodology that combines remote sensing and ground control on a sample of 558 sites documented by the Iraqi-Italian QADIS survey project. A three-tier typological framework has been created illustrating the risks jeopardising the cultural heritage of the region. This research showed that the most impacting risks are the ones caused by agricultural activity, despite current narratives which mainly focus on looting and violent destruction. To get at the root of the problem, current laws protecting cultural heritage in Iraq are analysed, as well as how the cultural authorities are organised on the ground. Improving the organisation of the SBAH, engaging the local communities towards the issue of sites’ protection and introducing preventive archaeology are among the solutions proposed.     

Variation in North American dart points and arrow points when one or both are present

The appearance of the bow and arrow in North America as a weapon-delivery system is predicted to have prompted an increase in variation among antecedent projectile points that tipped darts propelled by atlatls. Attributes of dart points are expected to display greater variation with the appearance of the bow as prehistoric artisans experimentally sought points that worked effectively as arrow points. Attributes of arrow points are predicted to also initially display much variation. Subsequent to the initial burst of variation, less-effective variants of attributes were winnowed out, causing a reduction in variation of attributes of both dart points and arrow points. Both coefficients of variation for individual attributes and summed coefficients of variation for multiple attributes of three sequences of projectile points from evolutionarily independent areas in North America confirm these predictions.     

Variation in Venues of Slavery and Freedom: Interpreting the Late Eighteenth-Century Cultural Landscape of St. John, Danish West Indies Using an Archaeological GIS

An archaeological GIS is used to examine the late eighteenth-century cultural landscape of St. John, US Virgin Islands. Land use patterns are reconstructed using a combination of historic maps, tax records, and survey reconnaissance. The study demonstrates significant, heretofore undocumented, transitions taking place that reflect dynamic cultural and economic change within Danish West Indian plantation society that includes a significant trend towards land ownership by free-colored St. Johnians more than a half a century before emancipation. These venues of freedom are discussed in relation to broader patterns of estate consolidation and economic shifts.     

Archaeological Explorations of Cultural Identity and Rural Economy in the North of Ireland: Goodland,County Antrim

Renewed examination of an enigmatic settlement site perched atop a cliff above Murlough Bay in Goodland Townland, County Antrim, Northern Ireland calls into question long held ideas about Gaelic rural economy on the eve of the Ulster Plantation by reintroducing the complex cultural and political relationships between the north of Ireland and the Scottish isles. Long interpreted as temporary post-medieval booley huts associated with seasonal transhumance, recent re-evaluation of the site suggests instead that Goodland represents a permanent seventeenth-century Highland Scottish village. Although the medieval linkages between the north of Ireland and the Scottish isles have long been acknowledged, twentieth-century sectarianism has subjugated awareness of the Highland (Roman Catholic) Scots focusing upon the legacy of the in-migration of Protestant Lowland Scots during the Ulster Plantation. Material evidence at Goodland re-introduces the Highland Scot to the contested landscape of contemporary Ulster identity, while also facilitating analysis of continuity, change, and cultural complexity in the rural economy of early modern Ireland.     

Detecting the effects of selection and stochastic forces in archaeological assemblages

Detecting and diagnosing the causes of change through time in archaeological assemblages is a core enterprise of archaeology. Evolutionary approaches to this problem typically cast the causes of culture change as being either stochastic in origin, or arising from selection. Stochastic sources of change include random innovations, copying errors, drift and founder effects among dispersing groups. Selection is driven by differences in payoffs between cultural variants. Most efforts to identify these evolutionary forces in the archaeological record have relied on assessing how well the predictions from a neutral-stochastic model of cultural transmission fit a data set. Selection is inferred when the neutral-stochastic model fits poorly. A problem with this approach is that it does not test directly for the presence selection. Moreover, it does not account for the fact that both neutral-stochastic and selective forces can act at the same time on the same cultural variants. A different approach based on the Price Equation allows for the simultaneous measurement of selective and stochastic forces. This paper extends use of the Price Equation to the analysis of selective and stochastic forces operating on multiple artifact types within an assemblage. Ceramic data presented by Steele et al. (2010, Vol. 37(6): 1348–1358) from the Late Bronze Age Hittite site of Bo?azköy-Hattusa, Turkey, provide an opportunity to evaluate the efficacy of this model. The results suggest that selection is a dominant process driving the frequency evolution of different bowl rim types within the assemblage and that stochastic forces played little or no role. It is also clear, however, that we should be attentive to combinations of direct and indirect selective effects within assemblages consisting of multiple artifact types.     

Depositional Context as the Foundation to Determining the Palaeolithic and Mesolithic Archaeological Potential of Offshore Wind Farm Areas in the Southern North Sea

Abstract

There is currently limited evidence on which to assess the submerged prehistoric potential in areas of renewable energy development. This paper presents a geomorphological approach to examine the Palaeolithic and Mesolithic archaeological potential in relation to the Round 3 offshore wind farm (OWF) areas of the southern North Sea. The depositional context and major stratigraphic correlations between the terrestrial sequence on east coast of Britain and offshore marine sequence of the southern North Sea are used to provide a first-order assessment for identifying horizons of archaeological interest in OWF zones. Using the examples Triton Knoll and East Anglia One OWF, the nature of renewable energy development on identified archaeological horizons is discussed, noting that any impact needs to be considered on a site-by-site basis. Studies are not only needed on the practical assessment of any development impact but also on the impacts of natural processes in OWF zones.     

Narratives and Bodies: Culture beyond the Cultural Turn

This article offers a fresh assessment of the current condition of ‘culturalist’ international history, exploring its achievements and limitations, taxonomising its key threads and charting an agenda for the future. It argues that at its heart lie two core concerns, one with narratives and the other with bodies. Thinking in this way allows us both to tie together work which initially appears disparate – endowing a bewilderingly diverse mass of scholarship with coherence and shape – and to better grasp the project's current trajectory. It analyses how these two issues rose to prominence, discussing not only the merits and failings of previous ‘culturalist’ work but also linkages with shifting debates in historical theory in the aftermath of the ‘postmodern’ turn. It explores the contours of the important work currently being conducted under these rubrics, drawing attention where appropriate to cognate scholarship in the discipline of International Relations with which international historians might profitably engage. Understanding the significance of these two core concepts provides vital orientation in contemporary intellectual debates within international history and enables us to push them on further.     

Ingesting the Material from Ganeshwar to Karbala: Reconstituting the Analytic and Recognizing Centrifugality in Archaeological Theory

First presented as part of the 2010 TAG Plenary session on Location of Theory, this short project questions archaeologies quest to locate theory. It posits that we reconsider the questions we ask to allow us to encounter the objects we study in a more intimate and visceral manner, providing them with properties that go beyond the social lives that we reconstruct for them.     

Caribou Crossings and Cultural Meanings: Placing Traditional Knowledge and Archaeology in Context in an Inuit Landscape

Meaning is conveyed by context. Northern landscapes associated with oral traditions provide rich contexts for understanding archaeological features and their spatial and temporal distribution. At the same time, traditional knowledge, including place names, is supported by the persistence of an integral archaeological landscape. The lower Kazan River, Nunavut Territory, Canada, preserves a record of land use for a hunting-trapping society in archaeological remains and traditional knowledge. The record shows that traditions of knowledge are manifest in the archaeological landscape. These traditions include commemoration of people and events in monuments, enduring practices (land skills) that are associated with a traditional time, and principles of spatial differentiation and orientation based on relations between people and caribou.

Archaeology in the Context of War: Legal Frameworks for Protecting Cultural Heritage during Armed Conflict

International law provides for a framework for protecting cultural heritage during armed conflict and for punishing those who transgress these principles. If understood within its limitations of dependence on state ratification and enforcement, international law protects cultural heritage by providing guidelines to those who wish to conform and by punishing after the fact those who deliberately destroy cultural heritage. Recent movement toward ratification of the 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict and its protocols by the major military powers should afford greater protection to cultural heritage in future conflicts.     

Toy Story: Homophily,Transmission and the Use of Simple Simulation Models for Assessing Variability in the Archaeological Record

The interpretation of spatial and temporal patterns in the archaeological record remains a long-standing issue in the discipline. Amongst many methods and interpretations, modelling of ‘biased transmission’ has proved a successful strategy to tackle this problem. Here, we investigate a type of biased transmission, homophily, that is the tendency of individuals to associate and bond with similar others. In contrast to other social sciences, homophily remains underused in archaeology. In order to fill this gap, we develop six distinct variants of a well-established modelling framework borrowed from social science, Axelrod’s Cultural Dissemination Model. These so-called toy models are abstract models used for theory-building and aim at exploring the interplay between homophily and various factors (e.g. addition of spatial features such as mountains and coastlines, diffusion of innovations and population spread). The relevance and implications of each ‘toy model’ for archaeological reasoning are then discussed.     

Elder Abuse: Evaluating the Potentials and Problems of Diagnosis in the Archaeological Record

The elderly are the most neglected demographic in archaeology. In today's youth‐obsessed society, the elderly are consistently denigrated, particularly those perceived to be physically or mentally frail. A related and growing concern in contemporary populations is the physical abuse of the elderly, believed to be an escalating phenomenon. This study is the first to examine the risk factors, social context and patterns of trauma associated with elder abuse in the present, with the aim of providing diagnostic criteria to apply to past societies. The utility of skeletal evidence in the identification of violent trauma has been detailed in cases of child and intimate partner abuse, both modern and archaeological. Investigating the skeletal evidence for elder abuse is potentially more complex because of the confounding physiological effects of the ageing process, lack of clinical research and contemporary ageist attitudes towards older people. Within the clinical and bioarchaeological literature, there has been a tendency to dismiss injuries in older individuals as the product of accident or opportunistic violence. A proportion of elder members of past societies is likely to have been victims of abuse and family violence. While there are no pathognomonic skeletal features of elder abuse, multiple injuries to the bones of the following are indicative: cranium, maxilla‐facial region, dentition, cervical vertebrae, clavicles, ribs and spiral fractures to the humeri. Attention is also drawn to decubiti as indirect skeletal indicators of immobility and possibly neglect. Archaeological context is important to consider, including non‐normative burials or those indicating social marginalisation. Bioarchaeological evidence has the potential to provide a long‐term perspective on the care and treatment of past elders. Copyright © 2015 John Wiley & Sons, Ltd.     

Ethinicity and Identity in the Archaeological Record (Reconstruction of an Excavation Completed in 1937 on a Chickasaw Village Site in Northeast Mississippi)

This article presents the restitution of an operation of excavation carried out in 1937 by Moreau Chambers on the site of a Chickasaw village. The objective of my research is to carry out a new analysis of the documents of the old excavations, to answer the interrogations concerning the way of life of Chickasaw at the beginning of the historical period and to reconstitute a site plan for this Chickasaw village. This operation included/understood also the handing-over of repatriated bodies. I also discuss the way in which my implication in this project interacted with my identity as a Chickasaw woman. The restitution of the operation of excavation, repatriation, and associated research contributed to show to the Chickasaw people the ways in which the law can help them. I finish this article by discussing the implications on the long term of the operation of Chambers for the modern archaeologists, the Chickasaw people, and Chickasaw who are themselves archaeologists.     

Archaeological,Historical, and Ethnographic Approaches to the Study of Sewn Boats: past,present, and future

Sewn‐plank vessels have been a pervasive form of ship construction since antiquity. This paper provides an introductory overview of the current state of the field of sewn‐plank studies, with a particular focus on the Indian Ocean. It describes the basic function of sewn‐plank techniques, and then discusses textual references and historical approaches to the topic. The relevant archaeological evidence is reviewed, and prior ethnographic work relating to the topic is outlined. It summarizes numerous experimental sewn‐plank reconstructions that have been undertaken and concludes with a discussion of the current directions of the field and suggestions for the future.     

Settlement and Subsistence in the Remote Western Pacific: Archaeological and Radiocarbon Data from Alamagan,Northern Mariana Islands

Small, remote islands were marginal environments for prehistoric human populations. We report archaeological and radiocarbon data from Alamagan, a small and isolated island in the northern part of the Mariana Islands archipelago. Challenging environmental conditions, including rugged terrain, active or recent volcanism, and uncertain freshwater availability posed significant challenges for permanent settlement throughout the Northern Islands. The Alamagan archaeological investigations documented 14 megalithic domestic structures, or latte sets, as well as isolated and non-portable Latte Period artifacts, and one historical site. Test excavations were undertaken at two of the latte features. These investigations add to a growing body of data suggesting colonization of the Northern Islands during the middle part of the Latte Period (probably during the late a.d. 1200s or early 1300s). We consider the implications of these data for the study of human adaptations to marginal insular environments in the Pacific.
