Exploring The Movement Of People In Postclassic And Historic Period Lamanai Using Stable Isotopes, Alicia E. Donis

Electronic Thesis and Dissertation Repository

The location of the Maya site of Lamanai on the New River Lagoon in northern Belize strategically situated it to participate in both coastal and inland trade routes and communication. This study of human burials at Lamanai examines the phosphate-oxygen isotope compositions of bone and enamel, which reflect drinking water and hence climatic zones, oxygen- and hydrogen-isotope compositions of modern local water, which provide a baseline for drinking water, and carbon- and nitrogen-isotope compositions of bone collagen, which reflect diet. The combination of isotopic, mortuary, osteological, and artifactual data is used to explore mobility at Lamanai during the Postclassic and …

A Comparison Of Mississippian Period Subadults From The Middle Cumberland And Eastern Regions Of Tennessee To Assess Health And Past Population Interactions, Rebecca Scopa Kelso

Doctoral Dissertations

Human subadult skeletal remains can provide a unique perspective into biosocial aspects of past populations. However, for a variety of reasons, they are often overlooked in the skeletal record. This is especially true for the Mississippian period (ca. 1000 years before present to ca. 400 years before present) populations that inhabited the Middle Cumberland region (MCR) and Eastern Tennessee Region (ETR). Most of the previous studies of these areas focused on adult skeletal remains, leaving out a large and extremely important population segment. To further expand current knowledge on the prehistory of the MCR and ETR, skeletal indicators of disease, …

Archaeological Geophysics, Excavation, And Ethnographic Approaches Toward A Deeper Understanding Of An Eighteenth Century Wichita Site, Michael Don Carlock

Graduate Theses and Dissertations

This research exemplifies a multidirectional approach to an archaeological interpretation of an eighteenth century Wichita village and fortification located on the Red River bordering Oklahoma and Texas. A battle that is believed to have occurred at the Longest site (34JF1) in 1759 between Spanish colonials and a confederation of Native Americans led to several Spanish primary documents describing the people that lived there, the fortification and surrounding village, and of course the battle itself. Investigation of the Longest site (34JF1) in Oklahoma presents a remarkable opportunity to combine extensive historical research, archaeological prospecting using geophysics, and traditional excavation techniques in …

An Anthropological Investigation Of The Dynamic Human-Vervet Monkey (Chlorocebus Aethiops Sabaeus) Interface In St. Kitts, West Indies, Kerry M. Dore

Theses and Dissertations

Over 350 years ago, the ecology of St. Kitts was dramatically altered by the advent of sugar cane production and the introduction of a highly adaptable, invasive animal species: the vervet monkey (Chlorocebus aethiops sabaeus). This project employed both primatological and ethnoprimatological techniques to assess conflict between vervet monkeys and Kittitian farmers. Methodological tools from primatology allowed for the creation of a predictive model of monkey crop-raiding behavior. The model was highly informative about monkeys' current raiding patterns; however, viewing Kittitian farmers and vervet monkeys as interconnected through an ethnoprimatological perspective revealed the significance of history with regard to this …

Issues Of Commingling Within The Gold Mine Site (16ri13) Collection: Adult Human Humeri And Tibiae, Kinsey Brett Stewart

Masters Theses

Gold Mine (16RI13) is a Troyville ossuary mound site (circa CE 825) in northeastern Louisiana. Approximately 10-20% of the primary mound (Mound A) was excavated over the course of three field seasons (1978-1980), yielding a host of human skeletal remains. Extensively commingled secondary burials make up the majority of interments. The number of individuals represented within the collection (N) has been estimated at 150+ (McGimsey 2004:214), but attempts to quantitatively determine N have produced varied results. Formal analysis of the skeletal collection is complicated by the loss of provenience for many remains as well as additional post-excavation fragmentation …

Concluding Remarks: What's In A Name? "Negritos" In The Context Of The Human Prehistory Of Southeast Asia, Stanley J. Ulijaszek

Human Biology

The "negrito" hypothesis posits that various indigenous groups throughout Island and Mainland Southeast Asia have a shared phenotype due to common descent from a putative ancestral population, representing a preagricultural substrate of humanity in the region. This has been examined and tested many times in the past, with no clear resolution. With many new resources to hand, the articles in this volume reexamine this hypothesis in a range of different ways. The evidence presented in this double issue of Human Biology speaks more against the category of "negrito" than for it. While populations with the negrito phenotype form a small …

The Australian Barrineans And Their Relationship To Southeast Asian Negritos: An Investigation Using Mitochondrial Genomics, Peter Mcallister, Nano Nagle, Robert John Mitchell

Human Biology

The existence of a short-statured Aboriginal population in the Far North Queensland (FNQ) rainforest zone of Australia’s northeast coast and Tasmania has long been an enigma in Australian anthropology. Based on their reduced stature and associated morphological traits such as tightly curled hair, Birdsell and Tindale proposed that these "Barrinean" peoples were closely related to "negrito" peoples of Southeast Asia and that their ancestors had been the original Pleistocene settlers of Sahul, eventually displaced by taller invaders. Subsequent craniometric and blood protein studies, however, have suggested an overall homogeneity of indigenous Australians, including Barrineans. To confirm this finding and determine …

Making Friends In The Rainforest: "Negrito" Adaptation To Risk And Uncertainty, Lye Tuck-Po

Human Biology

The so-called negritos adapt not just to a tropical forest environment but also to an environment characterized by perturbations and fluctuations. As with other hunter-gatherers in the region and, indeed, throughout the world, they use both social and ecological methods to enhance their chances of survival in this changing environment: socially, they have developed networks of trading and marriage partners; ecologically, they maintain patches of key resources that are available for future harvesting. As evidenced in the case of the Batek (Orang Asli), patterns of forest structure and composition are sometimes direct outcomes of intentional resource concentration and enrichment strategies. …

Why Have The Peninsular "Negritos" Remained Distinct?, Geoffrey Benjamin

Human Biology

The primary focus of this article is on the so-called negritos of Peninsular Malaysia and southern Thailand, but attention is also paid to other parts of Southeast Asia. I present a survey of current views on the "negrito" phenotype—is it single or many? If the phenotype is many (as now seems likely), it must have resulted from parallel evolution in the several different regions where it has been claimed to exist. This would suggest (contrary to certain views that have been expressed on the basis of very partial genetic data) that the phenotype originated recently and by biologically well-authenticated processes …

Terror From The Sky: Unconventional Linguistic Clues To The Negrito Past, Robert Blust

Human Biology

Within recorded history. most Southeast Asian peoples have been of "southern Mongoloid" physical type, whether they speak Austroasiatic, Tibeto-Burman, Austronesian, Tai-Kadai, or Hmong-Mien languages. However, population distributions suggest that this is a post-Pleistocene phenomenon and that for tens of millennia before the last glaciation ended Greater Mainland Southeast Asia, which included the currently insular world that rests on the Sunda Shelf, was peopled by short, dark-skinned, frizzy-haired foragers whose descendants in the Philippines came to be labeled by the sixteenth-century Spanish colonizers as "negritos," a term that has since been extended to similar groups throughout the region. There are three …

Time And Place In The Prehistory Of The Aslian Languages, Michael Dunn, Nicole Kruspe, Niclas Burenhult

Human Biology

The Aslian language family, located in the Malay Peninsula and southern Thai Isthmus, consists of four distinct branches comprising some 18 languages. These languages predate the now dominant Malay and Thai. The speakers of Aslian languages exhibit some of the highest degree of phylogenetic and societal diversity present in Mainland Southeast Asia today, among them a foraging tradition particularly associated with locally ancient, Pleistocene genetic lineages. Little advance has been made in our understanding of the linguistic prehistory of this region or how such complexity arose. In this article we present a Bayesian phylogeographic analysis of a large sample of …

Kinship Matters: Structures Of Alliance, Indigenous Foragers, And The Austronesian Diaspora, James West Turner

Human Biology

The study of kinship systems has direct relevance for the field of human genetics and the study of microevolution in human populations. Some types of postmarital residence rules—rules requiring a married couple to live with or near relatives of the husband or wife—will have consequences for the distribution of mitochondrial DNA and Y chromosome lineages. Rules that proscribe or encourage marriage with close kin will also have consequences for allele frequency. A preference for marrying at a distance, both socially and geographically, creates alliances that can have survival value for individuals and groups in an environment of periodic or unpredictable …

Who Are The Philippine Negritos? Evidence From Language, Lawrence A. Reid

Human Biology

This article addresses the linguistic evidence from which details about Philippine "negritos" can be inferred. This evidence comes from the naming practices of both negrito and non-negrito peoples, from which it can be inferred that many negrito groups have maintained a unique identity distinct from other groups since the dispersal of Malayo-Polynesian languages. Other names, such as Dupaningan and Dumagat, reference locations, from which it is assumed the negritos left after contact with Malayo-Polynesian people. Evidence also comes from the relative positions of negrito groups vis-à-vis other groups within the subfamily with which their current language can be grouped. Many …

Evolution Of The Pygmy Phenotype: Evidence Of Positive Selection From Genome-Wide Scans In African, Asian, And Melanesian Pygmies, Andrea Bamberg Migliano, Irene Gallego Romero, Mait Metspalu, Matthew Leavesley, Luca Pagani, Tiago Antao, Da-Wei Huang, Brad T. Sherman, Katharine Siddle, Clarissa Scholes, Georgi Hudjashov, Elton Kaitokai, Avis Babalu, Maggie Belatti, Alex Cagan, Bryony Hopkinshaw, Colin Shaw, Mari Nelis, Ene Metspalu, Reedik Mägi, Richard A. Lempicki, Richard Villems, Marta Mirazon Lahr, Toomis Kivisild

Human Biology

Human pygmy populations inhabit different regions of the world, from Africa to Melanesia. In Asia, short-statured populations are often referred to as "negritos." Their short stature has been interpreted as a consequence of thermoregulatory, nutritional, and/or locomotory adaptations to life in tropical forests. A more recent hypothesis proposes that their stature is the outcome of a life history trade-off in high-mortality environments, where early reproduction is favored and, consequently, early sexual maturation and early growth cessation have coevolved. Some serological evidence of deficiencies in the growth hormone/insulin-like growth factor axis have been previously associated with pygmies’ short stature. Using genome-wide …

Mount Pinatubo, Inflammatory Cytokines, And The Immunological Ecology Of Aeta Hunter-Gatherers, Robin M. Bernstein, Nathaniel J. Dominy

Human Biology

Early growth cessation and reproduction are predicted to maximize fitness under conditions of high adult mortality, factors that could explain the pygmy phenotype of many rainforest hunter-gatherers. This life-history hypothesis is elegant but contentious in part because it lacks a clear biological mechanism. One mechanism stems from the field of human immunological ecology and the concept of inflammation "memory" across the life cycle and into subsequent generations. Maternal exposures to disease can infl uence immunological cues present in breast milk; because maternal provisioning via lactation occurs during critical periods of development, it is plausible that these cues can also mediate …

Anthropology And Gis: Temporal And Spatial Distribution Of The Philippine Negrito Groups, Sabino G. Padilla Jr

Human Biology

The Philippine "negrito" groups comprise a diverse group of populations speaking over 30 different languages, who are spread all over the archipelago, mostly in marginal areas of Luzon Island in the north, the central Visayas islands, and Mindanao in the south. They exhibit physical characteristics that are different from more than 100 Philippine ethnolinguistic groups that are categorized as non-negritos. Given their numbers, it is not surprising that Philippine negritos make up a major category in a number of general ethnographic maps produced since the nineteenth century. Reports from various ethnological surveys during this period, however, have further enriched our …

Genetic Diversity Of Four Filipino Negrito Populations From Luzon: Comparison Of Male And Female Effective Population Sizes And Differential Integration Of Immigrants Into Aeta And Agta Communities, E Heyer, M Georges, M Pachner, P Endicott

Human Biology

Genetic data corresponding to four negrito populations (two Aeta and two Agta; n = 120) from the Luzon region of the Philippines have been analyzed. These data comprise mitochondrial DNA (mtDNA) hypervariable segment 1 haplotypes and haplogroups, Y-chromosome haplogroups and short tandem repeats (STRs), autosomal STRs, and X-chromosome STRs. The genetic diversity and structure of the populations were investigated at a local, regional, and interregional level. We found a high level of autosomal differentiation, combined with no significant reduction in diversity, consistent with long-term settlement of the Luzon region by the ancestors of the Agta and Aeta followed by reduced …

Admixture Patterns And Genetic Differentiation In Negrito Groups From West Malaysia Estimated From Genome-Wide Snp Data, Timothy A. Jinam, Maude E. Phipps, Naruya Saitou, The Hugo Pan-Asian Snp Consortium

Human Biology

Southeast Asia houses various culturally and linguistically diverse ethnic groups. In Malaysia, where the Malay, Chinese, and Indian ethnic groups form the majority, there exist minority groups such as the "negritos" who are believed to be descendants of the earliest settlers of Southeast Asia. Here we report patterns of genetic substructure and admixture in two Malaysian negrito populations (Jehai and Kensiu), using ~50,000 genome-wide single-nucleotide polymorphism (SNP) data. We found traces of recent admixture in both the negrito populations, particularly in the Jehai, with the Malay through principal component analysis and STRUCTURE analysis software, which suggested that the admixture was …

The Andaman Islanders In A Regional Genetic Context: Reexamining The Evidence For An Early Peopling Of The Archipelago From South Asia, Gyaneshwer Chaubey, Phillip Endicott

Human Biology

The indigenous inhabitants of the Andaman Islands were considered by many early anthropologists to be pristine examples of a "negrito" substrate of humanity that existed throughout Southeast Asia. Despite over 150 years of research and study, questions over the extent of shared ancestry between Andaman Islanders and other small-bodied, gracile, dark-skinned populations throughout the region are still unresolved. This shared phenotype could be a product of shared history, evolutionary convergence, or a mixture of both. Recent population genetic studies have tended to emphasize long-term physical isolation of the Andaman Islanders and an affinity to ancestral populations of South Asia. We …

Craniodental Affinities Of Southeast Asia's "Negritos" And The Concordance With Their Genetic Affinities, David Bulbeck

Human Biology

Genetic research into Southeast Asia's "negritos" has revealed their deep-rooted ancestry, with time depth comparable to that of Southwest Pacific populations. This finding is often interpreted as evidence that negritos, in contrast to other Southeast Asians, can trace much of their ancestry directly back to the early dispersal of Homo sapiens in the order of 70 kya from Africa to Pleistocene New Guinea and Australia. One view on negritos is to lump them and Southwest Pacific peoples into an "Australoid" race whose geographic distribution had included Southeast Asia prior to the Neolithic incursion of "Mongoloid" farmers. Studies into Semang osteology …

The Skeletal Phenotype Of "Negritos" From The Andaman Islands And Philippines Relative To Global Variation Among Hunter-Gatherers, Jay T. Stock

Human Biology

The "negrito hypothesis" suggests that populations of small-bodied foragers in South and Southeast Asia who share common phenotypic characteristics may also share a common, ancient origin. The key defining characteristics of the "negrito" phenotype, small body size, dark skin, and tightly curled hair, have been interpreted as linking these populations to sub-Saharan Africans. The underlying assumption of this interpretation is that the observed phenotypic similarities likely reflect shared ancestry rather than phenotypic convergence. Current genetic evidence is inconclusive, as it both demonstrates that negrito populations have genetic affinities with neighboring populations but also rare and ancient variation that suggests considerable …

"Small Size" In The Philippine Human Fossil Record: Is It Meaningful For A Better Understanding Of The Evolutionary History Of The Negritos?, Florent Détroit, Julien Corny, Eusebio Z. Dizon, Armand S. Mijares

Human Biology

"Pygmy populations" are recognized in several places over the world, especially in Western Africa and in Southeast Asia (Philippine "negritos," for instance). Broadly defined as "small-bodied Homo sapiens" (compared with neighboring populations), their origins and the nature of the processes involved in the maintenance of their phenotype over time are highly debated. Major results have been recently obtained from population genetics on present-day negrito populations, but their evolutionary history remains largely unresolved. We present and discuss the Upper Pleistocene human remains recovered from Tabon Cave and Callao Cave in the Philippines, which are potentially highly relevant to these research …

Hunter-Gatherers In Southeast Asia: From Prehistory To The Present, Charles Higham

Human Biology

Anatomically modern hunter-gatherers expanded from Africa into Southeast Asia at least 50,000 years ago, where they probably encountered and interacted with populations of Homo erectus and Homo floresiensis and the recently discovered Denisovans. Simulation studies suggest that these hunter-gatherers may well have followed a coastal route that ultimately led to the settlement of Sahul, while archaeology confirms that they also crossed significant seas and explored well into the interior. They also adapted to marked environmental changes that alternated between relatively cool and dry conditions and warmer, wetter interludes. During the former, the sea fell by up to 120 m below …

Introduction: Revisiting The "Negrito" Hypothesis: A Transdisciplinary Approach To Human Prehistory In Southeast Asia, Phillip Endicott

Human Biology

The "negrito" hypothesis predicts that a shared phenotype among various contemporary groups of hunter-gatherers in Southeast Asia - dark skin, short stature, tight curly hair - is due to common descent from a region-wide, pre-Neolithic substrate of humanity. The alternative is that their distinctive phenotype results from convergent evolution. The core issues of the negrito hypothesis are today more relevant than ever to studies of human evolution, including the out-of-Africa migration, admixture with Denisovans, and the effects of environment and ecology on life-history traits. Understanding the current distribution of the negrito phenotype dictates a wide-ranging remit for study, including the …

A Piece Of Nigromante In Boyle Heights, Javier Espinoza Barajas

LUX: A Journal of Transdisciplinary Writing and Research from Claremont Graduate University

My project conveys the role that individuals' faith in their cultural healing practices plays on their knowledge of the illness and on the actual healing process. More specifically, on how indigenous immigrant communities from Mexico are prone to utilize medical pluralism practices and experience culture-bound syndromes. When individuals migrate they take with them their understanding of disease, their ways to express it, and their ways of finding treatment according to their cultural medical practices. Based on this, I developed a project to explore the medical healing practices of twenty-three year old Claudia Velmontes during her pregnancy. Ms. Velmontes migrated to …

Dynamical Structure Of A Traditional Amazonian Social Network, Paul L. Hooper, Simon Dedeo, Ann E. Caldwell Hooper, Michael Gurven, Hillard Kaplan

ESI Publications

Reciprocity is a vital feature of social networks, but relatively little is known about its temporal structure or the mechanisms underlying its persistence in real world behavior. In pursuit of these two questions, we study the stationary and dynamical signals of reciprocity in a network of manioc beer (Spanish: chicha; Tsimane’: shocdye’) drinking events in a Tsimane’ village in lowland Bolivia. At the stationary level, our analysis reveals that social exchange within the community is heterogeneously patterned according to kinship and spatial proximity. A positive relationship between the frequencies at which two families host each other, controlling for kinship and …

Evaluation Of The Utility Of Deciduous Molar Morphological Variation In Great Ape Phylogenetic Analysis, Anna M. Hardin, Scott S. Legge

Scott Legge

Non-metric dental traits are well- established tools for anthropologists investigating population affiliation and movement in humans. Nonetheless, similar traits in the great apes have received considerably less attention. The present study provides data on non-metric trait variability in the deciduous molars of great apes from museum context. Twenty-eight traits are observed in the upper and lower deciduous molars in specimens of Pan troglodytes, Pan paniscus, Gorilla gorilla, and Gorilla beringei. These groups are compared based on trait frequencies and mean measures of divergence. This study demonstrates the variability of non-metric traits in the deciduous molars of chimpanzees and gorillas. These …

Genetic Variation Of X-Strs In The Wichí Population From Chaco Province, Argentina, Laura Angela Glesmann, Pablo Francisco Martina, Cecilia Inés Catanesi

Human Biology Open Access Pre-Prints

The Wichí people from Chaco province inhabit the region called Impenetrable Chaqueño, where the climatic conditions are extreme. Besides the scarce communication with the main urban centers, the cultural patterns of the Wichí cause these communities to live in certain degree of isolation. The effect of this situation is an increased genetic differentiation from other populations, as it was observed through autosomal and Y chromosome markers. However, the genetic variation of X chromosome has not been fully analyzed yet. The patterns of allele distribution of different markers of X chromosome can be highly informative in comparative studies, because its special …

Analysis Of Uniparental Lineages In Two Villages Of Santiago Del Estero, Argentina, Seat Of “Pueblos De Indios” In Colonial Times, Maia Pauro, Angelina García, Rodrigo Nores, Darío A. Demarchi

Human Biology Open Access Pre-Prints

Based on the analysis of the mitochondrial control region and seven biallelic markers of the Y Chromosome, we investigated the genetic composition of two rural populations of southern Santiago del Estero, Argentina, that were seats in colonial times of “pueblos de indios”, a colonial practice that consisted of concentrating the indigenous populations in organized and accessible settlements, to facilitate Christianizing and policing. We found the Native American Y chromosome haplogroup Q1a3a in only 11% (3/27) of the males. Haplogroup R, common in European populations, is the most frequent haplogroup in Santiago del Estero (55%). In contrast, the persistence of Native …

Patterns Of Senescence In Human Cardiovascular Fitness: Vo2 Max In Subsistence And Industrialized Populations, Anne C. Pisor, Michael Gurven, Aaron D. Blackwell, Hillard Kaplan, Gandhi Yetish

ESI Publications

Objectives—This study explores whether cardiovascular fitness levels and senescent decline are similar in the Tsimane of Bolivia and Canadians, as well as other subsistence and industrialized populations. Among Tsimane, we examine whether morbidity predicts lower levels and faster decline of cardiovascular fitness, or whether their lifestyle (e.g., high physical activity) promotes high levels and slow decline. Alternatively, high activity levels and morbidity might counterbalance such that Tsimane fitness levels and decline are similar to those in industrialized populations.

Methods—Maximal oxygen uptake (VO2max) was estimated using a step test heart rate method for 701 participants. We compared these estimates …
