All rights reserved. ii ACKNOWLEDGEMENTS When I started at the University of Tennessee in the fall of 2001, I would have told you that I was pursuing a career in forensic anthropology and will be getting myself out of Knoxville as soon as I could. Well several years later and an appreciation for the holistic approach to anthropology instilled by the faculty, I owe my development as a person and as an anthropologist to many individuals. First and foremost, I would like to thank Dr. Lee Meadows Jantz for taking me under her wing from the very first semester I was a teaching assistant for her osteology class to becoming her assistant at the Forensic Anthropology Center. She has supported me through this entire journey and gave this naïve girl wanting to do anthropology a chance. You have been there through the many trials of tribulations of life, both professionally and privately, and I could not have asked for a better mentor. I know I have gained a lifelong friend and colleague and hope I one day can repay you for all that you have taught me and all of the opportunities you have given me. I also owe a much need thank you to Dr. Darinka Mileusnic, who in the Spring of 2008 told me that I needed to start thinking about my own career. I was trying to do everything and it was taking its toll. It took me a few more years, but I finally understood. Thank you for forcing me to balance. Also, thank you Dr. Lyle Konigsberg for encouraging me to persevere. I appreciate your willingness to keep me as a student and sitting as my committee chair since leaving the university. You have provided me with valuable assistance, R code, and input on the dissertation. My goal was to prove to you I could do it and I hope I have. Thank you Dr. Kramer for showing me what it takes to be a teacher. iii None of this would be possible without the love of my family. I remember when I told my mother that I wanted to pursue anthropology instead of medicine. Her response was “well as long as you can support yourself.” Both my parents sacrificed and made sure that my siblings and I had the opportunities they did not, while allowing us to take our own path. I appreciate being allowed to find my own way. It may have taken me longer than most, but all that matters is that I did the best I could at the time. I also know I would not have been able to do any of this without my loving husband Anthony. You have taught me so much, including the type of person I should and want to be. Your endless patience with me putting everything but you first is more than anyone could ask. You will always be the epitome of southern hospitality in my eyes. It will take me a lifetime to repay you, but I am looking forward to it. A special thank you must be given to the Department of Anthropology secretaries, Pam, Pam, Charlene, and Donna. I have worked with you for many years and know first- hand you are the unsung heroes of the department. Thank you for all of the help, especially after I left the department. There are many people that have come into out of my life these last several years. All of you have played a role in my renewed dedication to a career in anthropology and have provided the inspiration and drive to complete this research. iv ABSTRACT The Arikara are one of the last Native American tribes to have direct contact with Europeans. Prior to westward expansion of Euro-American settlers, the Arikara served as middlemen in a complex trade network that brought European goods to the Upper Plains in exchange for fur and food items. In the 18th century with a growing European presence in the region, the Arikara experienced drastic bio-cultural and socio-political destabilization leading to population decline. However, these transitions are unclear because of limited written records prior to the early 19th century. Several hypotheses have been proposed to account for the near extinction of the Arikara tribe including warfare, inter- and intra-tribal conflict, disease, and resource stress. This research sought to better understand the population dynamics within the Larson Site. The Larson Site (39WW2) cemetery, a relatively unbiased and well- preserved skeletal assemblage (N=643), was re-analyzed to evaluate the demographic variability associated with increased European presence. The main focus of this research demonstrates how age-at-death estimation methods impact the mortality profiles and demographic measures derived from them. Traditional phase-base approaches, long bone skeletal development, Transition Analysis, and multifactorial approaches for both juvenile and adult individuals were used to compute age-at-death estimates for each individual within the cemetery. The point age-at-death estimates served as the basis for survival analysis via parametric hazards models. The Siler model was used to understand the overall pattern of mortality, while the Gompertz and Gompertz-Makeham models were used to explore adult-specific mortality patterns. The results indicate that the high number of juveniles and the relatively low survivorship of adults imply that the v population may have been experiencing a mortality event, like an epidemic. The high fertility and death rate must be incorporated into future models. Also, the overall patterning of the adult mortality is obscuring any sex-specific adult mortality pattern. This research is the beginning of a larger project to explore the utility of multi- state models of morbidity and mortality to better explain the population dynamics within the Larson Site and between the Larson and other Arikara villages. vi TABLE OF CONTENTS CHAPTER 1 ....................................................................................................................... 1 Introduction ......................................................................................................................... 1 Issues of Interpreting Population Change ....................................................................... 3 Age-at-death Estimation’s Impact on Demographic Model Building ............................ 7 Sex-Specific Adult Mortality ........................................................................................ 12 Summary ....................................................................................................................... 13 CHAPTER 2 ..................................................................................................................... 15 Archaeology and Cultural Affiliation of Larson Site (39WW2) ...................................... 15 Background ................................................................................................................... 15 Cultural Affiliation........................................................................................................ 16 The Archaeological Context ......................................................................................... 18 Dating of the Larson Village Site ................................................................................. 22 The Arikara ................................................................................................................... 23 Mortality ................................................................................................................... 26 Summary ....................................................................................................................... 31 CHAPTER 3 ..................................................................................................................... 32 Paleodemography

This principle—which argues for continuity in the evolved mechanisms 16 underlying modern human demographic processes and their response to environmental stimuli 17 between past and present— provides the cross-disciplinary basis for palaeodemographic 18 reconstruction and analysis. Prompted by the recent growth and interest in the field of prehistoric 19 demography, this paper reviews the principle of demographic uniformitarianism, evaluates how it 20 relates to two key debates in palaeodemographic research and seeks to delimit its range of 21 applicability to past human and hominin populations. 22 23 Keywords: Prehistoric demography; Uniformitarianism; Population dynamics; Life History; Archaic 24 hominins 25 1. Introduction 26 Like many historical sciences, prehistoric demography relies on a doctrine of uniformitarianism for 27 some of its foundational principles. Uniformitarianism is the adherence to the axiom that processes 28 that occurred in the past (and so cannot be directly experienced) were nonetheless likely to 29 resemble those that are observable in the present day.

Available at: http://digitalcommons.wayne.edu/humbiol/vol81/iss2/11 Climate and Demography in Early Prehistory: Using Calibrated 14C Dates as Population Proxies Abstract Although difficult to estimate for prehistoric hunter-gatherer populations, demographic variables—population size, density, and the connectedness of demes—are critical for a better understanding of the processes of material culture change, especially in deep prehistory. Demography is the middle-range link between climatic changes and both biological and cultural evolutionary trajectories of human populations. Much of human material culture functions as a buffer against climatic changes, and the study of prehistoric population dynamics, estimated through changing frequencies of calibrated radiocarbon dates, therefore affords insights into how effectively such buffers operated and when they failed. In reviewing a number of case studies (Mesolithic Ireland, the origin of the Bromme culture, and the earliest late glacial human recolonization of southern Scandinavia), I suggest that a greater awareness of demographic processes, and in particular of demographic declines, provides many fresh insights into what structured the archaeological record. I argue that we cannot sideline climatic and environmental factors or extreme geophysical events in our reconstructions of prehistoric culture change.

Defining palaeodemography: aims and scope 25 26 Demography is the study of human populations and their structure, i.e. the composition of 27 populations, and the subdivision of the metapopulation into smaller subunits. Palaeodemography 28 refers to the study of the demography of ancient populations for which there are no written sources 29 (broadly synonymous with ‘prehistoric demography’) [1]. Palaeodemography shares the core 30 aims of its present-day counterpart; namely, to document and explain changes within, and 31 variations between, the size and structure of human populations. However, by definition, no direct 32 demographic data–equivalent to modern-day censuses or registration forms–exist for prehistoric 33 populations. Instead, palaeodemographic information is derived from a wide range of proxies, 34 which only indirectly inform on demographic processes and parameters. 35 1 36 Accordingly, at present we consider palaeodemography to be less an independent field akin to 37 demography proper, and more an interlinked set of cross-disciplinary interests sharing the 38 common aims of reconstructing and analysing prehistoric population histories.

  • PRECONTACT POPULATION DECLINE and COALESCENCE in the SOUTHERN SOUTHWEST the Phoenix Basin Was the Heartland of the Hohokam Regional System for Nearly a Millennium
    PRECONTACT POPULATION DECLINE AND COALESCENCE IN THE SOUTHERN SOUTHWEST The Phoenix Basin was the heartland of the Hohokam regional system for nearly a millennium. Hundreds of miles of irrigation canals supported more than 20,000 people during the early 1300s, but the valley was devoid of inhabitants when the first Jesuit missionary visited the area in the 1690s (note all dates are A.D.). The magnitude of this population loss has been a topic of research for more than a century, yet there is still no widely accepted explanation. Furthermore, recent research has shown that the entire southern Southwest experienced a severe reduction in population prior to the arrival of Spaniards in the New World in 1540. Over the long term the American Southwest experienced population growth. What can account for such a dramatic reversal of this trend, and why is the decline so great in the southern Southwest? This proposal requests funding to investigate evidence of precontact population decline in the Phoenix Basin and three other areas in the southern Southwest. This research builds directly on work partly funded by NSF in the San Pedro Valley of southeastern Arizona. Our San Pedro Valley research revealed a complex demographic history, and we found that a theoretical model of coalescence helped us to understand the interrelationship of late precontact demographic processes. In the American Southeast, a similar coalescent society model has been applied to the early historic period when population decline and related disruptions led to cultural reorganization and formation of aggregated, multi-ethnic and multi-lingual communities. We postulate that a variety of social stresses stimulated the formation of coalescent communities in the Southwest by 1250 to 1300.

  • Demography of the Ðerdap Mesolithic–Neolithic Transition
    Demography of the Đerdap Mesolithic–Neolithic transition Mary Jackes, Mirjana Roksandić and Christopher Meiklejohn Abstract: Models for the Mesolithic–Neolithic transition are critically dependent on demographic variables. A major issue has been whether Mesolithic populations were stationary or increasing in demographic terms. The development of methods allowing for palaeodemographic comparison among archaeological skeletal samples provides the opportunity to test assumptions about the adequacy of samples and about changes in fertility during the European Late Mesolithic and Early Neolithic. Previous work has suggested that the Mesolithic was a period of stationary population in the far west and north of Europe, while the Neolithic brought with it a significant increase in fertility. We apply our standardized palaeodemographic methods to data from Ðerdap skeletal samples to examine whether period assignments need reassessment, and whether the Neolithic brought increased fertility to the Iron Gates region. Our conclusions indicate that continuing reassessment of the assignment of Lepenski Vir skeletons to archaeological periods is needed, that Mesolithic populations were stationary, and that there is a high probability for increased fertility rates in the Neolithic at Lepenski Vir. Keywords: Đerdap, demography, Mesolithic, Neolithic, transition, Lepenski Vir Introduction A key element of osteological work relates to the accurate determination of demographic variables. Problems involved The shift to food production and the Neolithic is one of the in the determination of skeletal age, especially in adults, are great transitions in human history.

  • Archaeology, Demography and Life History Theory Together Can Help Us
    Archaeology, demography and life history theory together can help us explain past and present population patterns Stephen Shennan and Rebecca Sear Published in ‘‘Cross-disciplinary approaches to prehistoric demography’ issue of Philosophical Transactions of the Royal Society, Series B, 2020 https://doi.org/10.1098/rstb.2019.0711 Abstract Population matters. Demography is both a cause and a consequence of human behaviour in other important domains, such as subsistence, cooperation, politics and culture. Demographers interested in contemporary and recent historical populations have rich data at their fingertips; the importance of demography means many interested parties have gathered demographic data, much of which is now readily available for all to explore. Those interested in the demography of the distant past are not so fortunate, given the lack of written records. Nevertheless, the emergence in recent years of a new interest in the demography of ancient populations has seen the development of a range of new methods for piecing together archaeological, skeletal and DNA evidence to reconstruct past population patterns. These efforts have found evidence in support of the view that the relatively low long-term population growth rates of prehistoric human populations, albeit ultimately conditioned by carrying capacities, may have been due to ‘boom-bust’ cycles at the regional level; rapid population growth, followed by population decline. In fact, this archaeological research may have come to the same conclusion as some contemporary demographers: that demography can be remarkably hard to predict, at least in the short term. It also fits with evidence from biology that primates, and particularly humans, may be adapted to environmental variability, leading to associated demographic stochasticity.

French McDonald Institute for Archaeological Research, Department of Archaeology and Anthropology, University of Cambridge, Downing Street, Cambridge, CB2 3DZ, UK Email: [email protected] Telephone: +44 (0)1223 338256 Abstract Demographic change has recently re-emerged as a key explanation for socio-cultural changes documented in the prehistoric archaeological record. While the majority of studies of Pleistocene demography have been conducted by geneticists, the archaeological records of the Palaeolithic should not be ignored as a source of data on past population trends. This paper forms both a comprehensive synthesis and the first critical review of current archaeological research into Palaeolithic demography. Within prevailing archaeological frameworks of dual inheritance theory and human behavioural ecology, I review the ways in which demographic change has been used as an explanatory concept within Palaeolithic archaeology. I identify and discuss three main research areas which have benefitted from a demographic approach to socio-cultural change; 1) technological stasis in the Lower Palaeolithic; 2) the Neanderthal-Homo sapiens transition in Europe, and; 3) the emergence of behavioural modernity. I then address the ways in which palaeodemographic methods have been applied to Palaeolithic data-sets, considering both general methodological concerns and the challenges specific to this time period. Finally, I discuss the ability of ethnographic analogy to aid research into Palaeolithic demography.
