forming four parallel time transects in Belize,
Brazil, the Central Andes, and the Southern Cone,
each dating to at least 9,000 years ago. The common
ancestral population radiated rapidly from just
one of the two early branches that contributed to
Native Americans today. We document two previously
unappreciated streams of gene flow between
North and South America. One affected the Central
Andes by 4,200 years ago, while the other explains
an affinity between the oldest North American
genome associated with the Clovis culture and the
oldest Central and South Americans from Chile,
Brazil, and Belize. However, this was not the primary
source for later South Americans, as the other
ancient individuals derive from lineages without
specific affinity to the Clovis-associated genome,
suggesting a population replacement that began
at least 9,000 years ago and was followed by substantial
population continuity in multiple regions.

hundreds of chronometric dates obtained from contexts dating prior to A.D.
1450, but until now these data have not been compiled into a single database.
Using dendrochronological, radiocarbon, and archaeomagnetic dates, we
analyze each of the chronometric data sets to identify patterns and biases that
help us better understand the tempo and duration of fundamental transitions
in the Mimbres archaeological record. We also identify critical gaps in our knowledge
of the chronometric record that provide new research opportunities.
Muchas décadas de investigación arqueológica en la región Mimbres han resultado

han sido compilados en una sola base comprensiva. Utilizando fechas dendrocronológicas, radiocarbónicas, y arqueomagnéticas, nosotros analizamos cada
conjunto de datos cronométricos para identificar atributos y prejuicios. Como
resultado, podemos comprender mejor el ritmo y la duración de transiciones

Although scholars have mentioned Woodrow Ruin for over 80 years, little professional research has been performed there. During the summer of 2011 researchers from the University of Colorado, Arizona State University, Museum of New Mexico, and Desert Archaeology conducted research at Woodrow Ruin. The research consisted of a surface ceramic survey and high-contour GPS mapping, and was the most extensive to date at the site. This article examines the history of research at Woodrow Ruin, describes current work at the site, and suggests that Woodrow Ruin can help elucidate some long-standing issues in Mimbres archaeology.

More recently, scholars have begun to challenge these works, rejecting the notion of collapse altogether in favor of focusing on concepts such as resilience and transformation. Driven by these developments, archaeologists have turned their attention to what occurs in the aftermath of sociopolitical decline, attempting to identify factors that contribute to the regeneration, transformation, or reorganization of complex sociopolitical institutions. Subsequent research has provided important data shedding light on political environments that were once characterized as “dark ages.” In that time, general theoretical approaches have transformed as well, and recent frameworks reconsider collapse and reorganization not as unrelated or sequential phenomena but as integral components in a cyclical understanding of the evolution of complex societies. The most recent of these approaches incorporates the tenets of Resilience Theory, as developed by environmental scientists.
In March 2013, an international conference held at Southern Illinois University in Carbondale brought together scholars with diverse theoretical perspectives to present and synthesize new data and approaches to understanding the collapse and reorganization of complex societies. No restrictions were imposed regarding chronological periods, geographical regions or material specialties, resulting in a wide-ranging potential for comparative analysis. This publication is the outcome of that meeting. It is not organized merely as a collection of diverse case studies, but rather a collaborative effort incorporating various data sets to evaluate and expand on theoretical approaches to this important subject. The works contained within this volume are organized into five sections: the first sets the stage with introductory papers by the editor and distinguished contributor, Joseph Tainter; the second contains works by distinguished scholars approaching collapse and reorganization from new theoretical perspectives; the third presents critical archaeological analyses of the effectiveness of Resilience Theory as a heuristic tool for modeling these phenomena; the fourth section presents long-term adaptive strategies employed by prehistoric societies to cope with stresses and avoid collapse; the final section highlights new research on post-decline contexts in a variety of temporal and geographic ranges and relates these data to the more comprehensive works on the subject.

Prior explorations of the Mimbres Late Pithouse to Classic transition have lacked data from one of the largest sites in the region. Woodrow Ruin is a large, multi-component site that had previously received little professional investigation. Fieldwork at Woodrow Ruin for this dissertation demonstrated that it had a long, continuous occupation with a dense population during the Transitional period. Numerous techniques were used to procure data on the occupational history of Woodrow Ruin, and Late Pithouse to Classic period transformations. Surface survey, GPS mapping, and magnetometry were used to assess the number of structures present at the site and how the site’s population transformed through time. Eight structures were excavated to provide information on the Late Pithouse, Transitional, and Classic period occupations of the site. Ceramics, chipped stone, and botanical material from those structures was used to assess changes in subsistence, trade, and interaction between the Late Pithouse and Classic periods.
Earlier archaeological investigations of the Mimbres Late Pithouse to Classic transition focused primarily on architecture. Data from Woodrow Ruin indicate that while significant architectural alterations occurred, these were only part of a suite of dramatic of transformations. Evidence of changes in trade and exchange networks, ritual practices, ideology, and social structure during the Transitional period were all found at Woodrow Ruin.
Along with delineating multiple Transitional period changes, this dissertation examines causal factors for the Late Pithouse to Classic transformations. Environmental data indicates that the Transitional period occurred during a prolonged, severe drought. Resilience and vulnerability theories are used to examine the interplay of drought and social transformations during the Mimbres Transitional period. Anthropologists and archaeologists have used vulnerability and resilience to better understand socio-ecological transformations. Expectations from these theories suggest that while the inhabitants of Woodrow Ruin were susceptible prolonged drought during the tenth century, they were able to persist and stay in place through social reorganization.

Although archaeologists have long recognized that projectile points could have multiple functions, few have examined the social and symbolic functions these objects had. This article discusses the thorough examination of ethnographic documents primarily from the US Southwest written during the nineteenth and twentieth centuries, which reveal that stone projectile points had multiple social and symbolic functions. After a discussion of the compiled ethnographic data, data from the analysis of over 600 stone points from the northern U.S. Southwest dating to AD 900-1300 is presented. The stone projectile point data reveals that while the majority of projectile points were used as tips to arrows, some did serve social and symbolic functions similar to those observed in the ethnographic record. With this data in hand, I argue that archaeologists must approach projectile points as more than just weapons, and that analysis of these objects can reveal much more about the past than simply chronology and cultural boundaries.

This paper examines some of the earliest documents from Spanish exploration and colonization in the Southwest, and examines how they can inform the archaeological record. Specific attention is paid to southwest New Mexico, which has received less attention than the pueblo north. Issues of applying ethnohistoric sources to the archaeological record are also addressed.

Drawing on Cameron’s extensive examination of ethnohistoric data on captivity, we realized that biomolecular data could allow us to access the occurrence of this practice in the past, and that it is likely an important factor in the migrations and population transformations recently identified through biomolecular techniques. We therefore introduce captive-taking, particularly the coerced integration of non-local women into a captor’s society through raiding, warfare, or “marriage,” as a possible explanation for some of the patterns
emerging from biomolecular studies. The goal of this study is to provide a model that we believe will be useful for interpreting at least some of the trends identified in new biomolecular data.
