The Caves Of Barbuda’S Eastern Coast: Long Term Occupation, Ethnohistory And Ritual, Sophia Perdikaris, Sandrine Grouard, George Hambrecht, Megan Hicks, Anjana Mebane-Cruz, Reaksha Persaud

School of Global Integrative Studies: Faculty Publications

Barbuda is the sister island to Antigua, located in the Lesser Antilles, West Indies. This island belongs to the Miocene arch of the Lesser Antilles, along with Grande Terre of Guadeloupe, Marie Galante, and Anguilla. Barbuda, notwithstanding its small size and low elevation, has an exceptionally rich past. Recent investigations by a Brooklyn College, City University of New York led team, has discovered evidence of human activity in and around these caves from the Archaic Period down to the present day. The range of activity at these caves begins with scatters of Archaic lithics, through artifacts and faunal material possibly …

Modernization, Sexual Risk-Taking, And Gynecological Morbidity Among Bolivian Forager-Horticulturalists, Jonathan Stieglitz, Aaron D. Blackwell, Raúl Quispe Gutierrez, Edhitt Cortez Linares, Michael Gurven, Hillard Kaplan

ESI Publications

Sexual risk-taking and reproductive morbidity are common among rapidly modernizing populations with little material wealth, limited schooling, minimal access to modern contraception and healthcare, and gendered inequalities in resource access that limit female autonomy in cohabiting relationships. Few studies have examined how modernization influences sexual risk-taking and reproductive health early in demographic transition. Tsimane are a natural fertility population of Bolivian forager-farmers; they are not urbanized, reside in small-scale villages, and lack public health infrastructure. We test whether modernization is associated with greater sexual risk-taking, report prevalence of gynecological morbidity (GM), and test whether modernization, sexual risk-taking and parity are …

Why Do Women Have More Children Than They Want? Understanding Differences In Women's Ideal And Actual Family Size In A Natural Fertility Population, Lisa Mcallister, Michael Gurven, Hillard Kaplan, Jonathan Stieglitz

ESI Publications

Objectives—We develop and test a conceptual model of factors influencing women’s ideal family size (IFS) in a natural fertility population, the Tsimane of Bolivia. The model posits affects of socioecology, reproductive history, maternal condition, and men’s IFS. We test three hypotheses for why women may exceed their IFS despite experiencing socioeconomic development: (H1) limited autonomy; (H2) improved maternal condition; and (H3) low returns on investments in embodied capital.

Methods—Women’s reproductive histories and prospective fertility data were collected from 2002 to 2008 (n = 305 women). Semistructured interviews were conducted with Tsimane women to study the perceived value of …

Fatty Acid Composition In The Mature Milk Of Bolivian Forager-Horticulturalists: Controlled Comparisons With A Us Sample, Melanie A. Martin, William D. Lassek, Steven J. C. Gaulin, Rhobert W. Evans, Sheela S. Geraghty, Barbara S. Davidson, Ardythe L. Morrow, Hillard Kaplan, Michael Gurven

ESI Publications

Breast milk fatty acid (FA) composition varies greatly among individual women, including in percentages of the long-chain polyunsaturated FAs (LCPUFA) 20:4n-6 (arachidonic acid, AA) and 22:6n-3 (docosahexaenoic acid, DHA), which are important for infant neurological development. It has been suggested that owing to wide variation in milk LCPUFA and low DHA in Western diets, standards of milk FA composition should be derived from populations consuming traditional diets. We collected breast milk samples from Tsimane women at varying lactational stages (6–82 weeks). The Tsimane are an indigenous, natural fertility, subsistence-level population living in Amazonia Bolivia. Tsimane samples were matched by lactational …

From The Womb To The Tomb: The Role Of Transfers In Shaping The Evolved Human Life History, Michael Gurven, Jonathan Stieglitz, Paul L. Hooper, Cristina Gomes, Hillard Kaplan

ESI Publications

Humans are the longest living and slowest growing of all primates. Although most primates are social, humans are highly cooperative and social in ways that likely co-evolved with the slow human life history. In this paper we highlight the role of resource transfers and non-material assistance within and across generations in shaping low human mortality rates. The use of complex cooperative strategies to minimize risk is a necessary precursor for selecting further reductions in mortality rate in late adulthood. In conjunction with changes in the age-profile of production, the impacts of resource transfers and other forms of cooperation on reducing …

Dental Microwear Texture Analysis Of Pliocene Bovids From Four Early Hominin Sites In Eastern Africa: Implications For Paleoenvironmental Dynamics And Human Evolution, Jessica Renee Scott

Graduate Theses and Dissertations

Many researchers have suggested that Plio-Pleistocene climate change was a motive force for human evolution. The basic idea was that a shift toward drier, more open settings, led to adaptations for bipedality and the consumption of savanna resources, including large grazing mammals. However, more recent paleoenvironmental reconstructions suggest that Pliocene hominins occupied variable or mosaic habitats including both open and closed settings. Many techniques have been used to refine our understanding of the paleoenvironments of eastern Africa; however these have not led to consensus reconstructions. At Kanapoi, ecological diversity analysis indicates that at least part of the site was composed …

Infidelity, Jealousy, And Wife Abuse Among Tsimane Forager-Farmers: Testing Evolutionary Hypotheses Of Marital Conflict, Jonathan Stieglitz, Michael Gurven, Hillard Kaplan, Jeffrey Winking

ESI Publications

What causes marital conflict, and which marital conflicts are more likely to result in men’s violence against their wives? It has long been argued that men’s jealousy over women’s infidelity is the strongest impetus to men’s lethal and non-lethal violence against female partners. Less is known about the extent to which women’s jealousy over men’s infidelity precipitates men’s violence against female partners. Husbands are more likely than wives to commit infidelity, and men and women report a similar frequency and intensity of jealous emotions during recalls of potential infidelity. If men are likely to use time and resources for pursuit …

Protection Of The Natural And Cultural Heritage Of The Mongolian Altai, Ulikpan Beket, Hans D. Knapp

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The Altai-Sayan Ecoregion is known as a hotspot of biodiversity with large wilderness landscapes and a high rate of endemism in Central Asia and Siberia. There are many large and important protected areas of different categories. Parts of the Russian Altai, the “Golden Mountains of Altai”, are inscribed as World Natural Heritage. Also the neighbouring countries contain pristine landscapes, which could be a potential for an extension to a transnational serial World Heritage Site.

The Mongolian part of the ecoregion is characterized by very diverse landscapes and vegetation complexes: Deserts, semi-deserts and desert steppes in arid basins, river floodplains, salt …

Evidence For A Peak Shift In A Humoral Response To Helminths: Age Profiles Of Ige In The Shuar Of Ecuador, The Tsimane Of Bolivia, And The U.S. Nhanes, Aaron D. Blackwell, Michael D. Gurven, Lawrence S. Sugiyama, Felicia C. Madimenos, Melissa A. Liebert, Melanie A. Martin, Hillard Kaplan, J. Josh Snodgrass

ESI Publications

Background: The peak shift model predicts that the age-profile of a pathogen’s prevalence depends upon its transmission rate, peaking earlier in populations with higher transmission and declining as partial immunity is acquired. Helminth infections are associated with increased immunoglobulin E (IgE), which may convey partial immunity and influence the peak shift. Although studies have noted peak shifts in helminths, corresponding peak shifts in total IgE have not been investigated, nor has the age-patterning been carefully examined across populations. We test for differences in the agepatterning of IgE between two South American forager-horticulturalist populations and the United States: the Tsimane …

Inflammatory Gene Variants In The Tsimane, An Indigenous Bolivian Population With A High Infectious Load, Sarinnapha Vasunilashorn, Caleb E. Finch, Eileen M. Crimmins, Suvi A. Vikman, Jonathan Stieglitz, Michael Gurven, Hillard Kaplan, Hooman Allayee

ESI Publications

The Tsimane of lowland Bolivia are an indigenous forager-farmer population living under conditions resembling pre-industrial European populations, with high infectious morbidity, high infection and inflammation, and shortened life expectancy. Analysis of 917 persons ages 5 to 60+ showed that allele frequencies of 9 SNPs examined in the apolipoprotein E (apoE), C-reactive protein (CRP), and interleukin-6 (IL-6) genes differed from some European, African, and north Asian-derived populations. The apoE2 allele was absent, whereas four SNPs related to CRP and IL-6 were monomorphic: CRP (rs1800947, rs3093061, and rs3093062) and IL-6 (rs1800795). No significant differences in apoE, CRP, and IL-6 variants across age …

Father Death And Adult Success Among The Tsimane: Implications For Marriage And Divorce, Jeffrey Winking, Michael Gurven, Hillard Kaplan

ESI Publications

Human fathers are heavily involved in the rearing of children around the world. While there is great cross-cultural variation, the father is a recognizable role in all populations. This deviates from the standard mammalian pattern of little paternal investment. A logical explanation offered early by evolutionary theorists is that human fathers evolved the capacity for paternal concern because human children are remarkably needy and impose a great encumbrance on the mother (Lancaster & Lancaster, 1983; Lovejoy, 1981). Thus, fathers have greater opportunity to enhance the wellbeing of child and mother, as there is a deeper well of need to fill. …

Blood Lipids, Infection, And Inflammatory Markers In The Tsimane Of Bolivia, Sarinnapha Vasunilashorn, Eileen M. Crimmins, Jung Ki Kim, Jeff Winking, Michael Gurven, Hillard Kaplan, Caleb Finch

ESI Publications

Objectives—Little is known about blood cholesterol (blood-C) levels under conditions of infection and limited diet. This study examines blood-C and markers of infection and inflammation in the Tsimane of the Bolivian Amazon, indigenous forager farmers living in conditions that model preindustrial European populations by their short life expectancy, high load of infections and inflammation, and limited diets.

Methods—We use multivariate models to determine the relationships between lipid levels and markers of infection and inflammation. Adult Tsimane (N = 418, age 20–84) were characterized for blood lipids, cells, and inflammatory markers in relation to individual loads of parasites and …

The Social Strategy Game: Resource Competition Within Female Social Networks Among Small-Scale Forager-Horticulturalists, Stacey L. Rukas, Michael Gurven, Hillard Kaplan, Jeffrey Winking

ESI Publications

This paper examines social determinants of resource competition among Tsimane Amerindian women of Bolivia. We introduce a semi-anonymous experiment (the Social Strategy Game) designed to simulate resource competition among women. Information concerning dyadic social relationships and demographic data were collected to identify variables influencing resource competition intensity, as measured by the number of beads one woman took from another. Relationship variables are used to test how the affiliative or competitive aspects of dyads affect the extent of prosociality in the game. Using a mixed-modeling procedure, we find that women compete with those with whom they are quarreling over accusations of …

Temporal And Spatial Variations In Freshwater 14C Reservoir Effects: Lake Mývatn, Northern Iceland, Philippa L. Ascough, G. T. Cook, M. J. Church, E. Dunbar, Á. Einarsson, Thomas H. Mcgovern, A. J. Dugmore, Sophia Perdikaris, H. Hastie, A. Friðriksson, H. Gestsdóttir

School of Global Integrative Studies: Faculty Publications

Lake Mývatn is an interior highland lake in northern Iceland that forms a unique ecosystem of international scientific importance and is surrounded by a landscape rich in archaeological and paleoenvironmental sites. A significant freshwater reservoir effect (FRE) has been identified in carbon from the lake at some Viking (about AD 870–1000) archaeological sites in the wider region (Mývatnssveit). Previous accelerator mass spectrometry (AMS) measurements indicated this FRE was about 1500–1900 ¹⁴C yr. Here, we present the results of a study using stable isotope and ¹⁴C measurements to quantify the Mývatn FRE for both the Viking and modern periods. …

School of Global Integrative Studies: Faculty Publications

Thomas H. McGovern has been a pioneering researcher in the North Atlantic region for most of the past 40 years. He has taken his specialty in zooarchaeology beyond counting bones to actually addressing questions about human environment interactions and human response to extreme environmental events. A prolific writer and researcher with a multitude of publications and an impressive funding record, McGovern has always been a proponent of multidisciplinarity and international collaboration. His vision resulted in the creation of the North Atlantic Biocultural Organization (NABO) that currently has more than 400 scientific partners and has been leading projects throughout the Circum …

Inflammation And Infection Do Not Promote Arterial Aging And Cardiovascular Disease Risk Factors Among Lean Horticulturalists, Michael Gurven, Hillard Kaplan, Jeffrey Winking, Daniel Eid Rodriguez, Sarinnapha Vasunilashorn, Jung Ki Kim, Caleb Finch, Eileen M. Crimmins

ESI Publications

Background: Arterial aging is well characterized in industrial populations, but scantly described in populations with little access to modern medicine. Here we characterize health and aging among the Tsimane, Amazonian forager-horticulturalists with short life expectancy, high infectious loads and inflammation, but low adiposity and robust physical fitness. Inflammation has been implicated in all stages of arterial aging, atherogenesis and hypertension, and so we test whether greater inflammation associates with atherosclerosis and CVD risk. In contrast, moderate to vigorous daily activity, minimal obesity, and low fat intake predict minimal CVD risk among older Tsimane.

Methods and Findings: Peripheral arterial …

A Bioeconomic Approach To Marriage And The Sexual Division Of Labor, Michael Gurven, Jeffrey Winking, Hillard Kaplan, Christopher Von Rueden, Lisa Mcallister

ESI Publications

Children may be viewed as public goods whereby both parents receive equal genetic benefits yet one parent often invests more heavily than the other.We introduce a microeconomic framework for understanding household investment decisions to address questions concerning conflicts of interest over types and amount of work effort among married men and women. Although gains and costs of marriage may not be spread equally among marriage partners, marriage is still a favorable, efficient outcome under a wide range of conditions. This bioeconomic framework subsumes both cooperative and conflictive views on the sexual division of labor. We test hypotheses concerning marriage markets, …

The Tadpole Of Hypsiboas Atlanticus (Anura, Hylidae) From Northeastern Brazil, Filipe A. C. Do Nascimento, Marcelo G. De Lima, Gabriel O. Skuk, Rafael O. De Sá

Biology Faculty Publications

The tadpole of Hypsiboas atlanticus (Caramaschi & Velosa, 1996) is described from the municipality of Maceió, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1). The oral disc is surrounded, almost completely (anterior medial gap present) by a single row of marginal papillae. Described tadpoles of the H. punctatus species group can be differentiated by a combined disc oral features. Additional descriptions of H. punctatus (Schneider, 1799) tadpoles from populations throughout South America may be helpful in determining …

The Multiple Dimensions Of Male Social Status In An Amazonian Society, Christopher Von Rueden, Michael Gurven, Hillard Kaplan

ESI Publications

"In all human societies, individuals differ in social status depending upon their age and personal ability (Sahlins, 1958; Service, 1971). In laboratory-based small group studies, status hierarchies emerge spontaneously (Bass, 1954; Campbell et al., 2002; Kalma, 1991). Even among “egalitarian” foragers, who are characterized by widespread resource sharing (Kaplan & Gurven, 2005; Winterhalder, 1986) and some degree of status-leveling (Cashdan, 1980), certain individuals consume more resources, get the best pick of mates, and take a more central role in group decision-making (Boehm, 1999; Trigger, 1985; Wiessner, 1996). Whether implicit or overt, classification by social status is a human universal. While …

Aging And Inflammation In Two Epidemiological Worlds, Michael Gurven, Hillard Kaplan, Jeffrey Winking, Caleb Finch, Eileen M. Crimmins

ESI Publications

Humans evolved in a world with high levels of infection resulting in high mortality across the life span and few survivors to advanced ages. Under such conditions, a strong acute-phase inflammatory response was required for survival; however, inflammatory responses can also promote chronic diseases of aging. We hypothesize that global historical increases in life span at older ages are partly explained by reduced lifetime exposure to infection and subsequent inflammation. To begin a test of this hypothesis, we compare C-reactive protein (CRP); levels in two populations with different epidemiological environments: the Tsimane of Bolivia and persons in the United States. …

Cod Fish, Walrus, And Chieftains: Economic Intensification In The Norse North Atlantic, Sophia Perdikaris, Thomas H. Mcgovern

School of Global Integrative Studies: Faculty Publications

Introduction

Just over a thousand years ago, Scandinavian voyagers crossed the grey waters of the North Atlantic to briefly explore the coast of North America. These now well publicized transatlantic trips were part of larger economic, environmental, and social developments of the Viking Age, and were the product of an Iron Age chiefly society with a complex economy incorporating both classic “prestige goods” and “staple goods” components. The Viking Age expansion was the result of linked factors of economic intensification, military and technological advances, climate change, and intense com-petition among chiefly elites and between elites and commoners. The period saw …

An Interim Report Of The Viking Age Archaeofauna From Hrísheimar, Mývatn District, N Iceland, Thomas H. Mcgovern, Sophia Perdikaris, Ramona Harrison, Konrad Smiarowski, Norie Manigault

School of Global Integrative Studies: Faculty Publications

The excavations at Hrísheimar in Mývatnssveit in N Iceland are producing a very large archaeofauna, which can now be dated through both radiocarbon and two major volcanic tephra layers (the Landnám tephra of ca AD 871 and the Veiðivötn 930 tephra). While much of the site has been destroyed by wind erosion, substantial midden deposits (which overly earlier structures in some cases) still remain along the NE edge of the site area. While excavation is ongoing and only a small portion of the very substantial archaeofauna has been analyzed so far, it may be useful to present an interim working …

An Interim Report Of A Viking-Age & Medieval Archaeofauna From Undir Junkarinsfløtti, Sandoy, Faroe Islands, Thomas H. Mcgovern, Colin Amundsen, Sophia Perdikaris, Ramona Harrison, Yekaterina Krivogorskaya

School of Global Integrative Studies: Faculty Publications

Cooperative international excavations at the site of Undir Junkarinsfløtti (27020) in the village of Sandur on the island of Sandoy, Faroe Islands in May 2003 recovered a stratified bone - rich midden deposit extending from the Viking Age to the early medieval period. The animal bone collection contains domestic mammals (cattle, sheep, dog, goat, and pig) and substantial amounts of fish (mainly cod), birds (mainly puffin and guillemot), and shellfish (mainly limpet). While the current collection has the archaeological limitations inherent in column samples, it suggests persistence of substantial pig keeping into the 13th c, and strongly indicates a sustainable …

A 15th C. Archaeofauna From Akurvík, An Early Fishing Station In Nw Iceland, Colin Amundsen, Sophia Perdikaris, Matthew Brown, Yekaterina Krivogorskaya, Salena Modugno, Konrad Smiarowski, Shaye Storm, Malgorzata Frik, Monica Koczela, Thomas H. Mcgovern

School of Global Integrative Studies: Faculty Publications

This is a report of analysis of 15th c bone materials from the site of Akurvík in NW Iceland excavated in 1990. A small international project in Árneshreppur district recovered a series of stratified midden deposits associated with small turf structures on an eroding beachfront. Radiocarbon dates identify at least two major phases of occupation and use, one extending into the mid 13th century, and the other dating to the mid 15th century. This report documents the animal bone collection from the later 15th c occupation. Dominated by cod fish, these deposits appear to be the product of seasonal fishery …

Animal Bones From Sondum (27012) Sandoy, Faroe Islands 200 Season Collection, Thomas H. Mcgovern, Seth Brewington, Sophia Perdikaris, Colin Amundsen

School of Global Integrative Studies: Faculty Publications

Introduction

This paper reports on analysis of animal bones collect in 2000 by the Faroese Museum from a stratified but eroding beach front cliff in on the island of Sandoy. The site designation is Sondum, 27012 and the bone materials have been kindly sent to the CUNY laboratories for analysis by the excavator Simun Arge. While conditions of bone preservation are not as good as at the Undir Junkarinsfløtti locality to the SW across the embayment, and sample size is much smaller, a substantial amount of bone was recovered from datable which adds to our understanding of early economic patterns …

Coping With Hard Times In Nw Iceland: Zooarchaeology, History, And Landscape Archaeology At Finnbogastaðir In The 18th Century, Ragnar Edvarsson, Sophia Perdikaris, Thomas H. Mcgovern, Noah Zagor

School of Global Integrative Studies: Faculty Publications

During a cooperative archaeological project in NW Iceland (Strandasýsla) involving the Icelandic National Museum and Hunter College of the City University of New York.1990 season, a small rescue excavation at the site of Finnbogastaðir generated a quantifiable collection of animal bones dating to the early modern period, mainly to the 18th century. The 18th c was a period of hardship in much of Iceland, with widespread tenantry, adverse climate, and degradation of many terrestrial landscapes posing severe challenges to poor farmers- perhaps most intensely in the Vestfirðir. The animal bone collection from Finnbogastaðir reflects a multi-stranded subsistence economy involving seals, …

The Evolution Of Human Life Expectancy And Intelligence In Hunter-Gatherer Economies, Hillard Kaplan

ESI Publications

The economics of hunting and gathering must have driven the biological evolution of human characteristics, since hunter-gatherer societies prevailed for the two million years of human history. These societies feature huge intergenerational resource flows, suggesting that these resource flows should replace fertility as the key demographic consideration. It is then theoretically expected that life expectancy and brain size would increase simultaneously, as apparently occurred during our evolutionary history. The brain here is considered as a direct form of bodily investment, but also crucially as facilitating further indirect investment by means of learning-by-doing.

Bioarchaeology And Cod Fisheries: A New Source Of Evidence, Thomas Amorosi, Thomas H. Mcgovern, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

Archaeological excavations in the North Atlantic basin over the past two decades have recovered large amounts of fishbones from datable deposits extending back over 8000 years in some areas. Coverage of the last 1000 years (with particular emphasis on the climatic cooling of the “Little Ice Age”) is increasingly complete. Recent research makes it possible to reconstruct live lengths from commonly recovered fishbone elements. Preliminary findings indicate that cod of 1 to 1.5 m were being regularly taken in the eleventh to nineteenth centuries throughout the North Atlantic. Changes in fish size and mix of species taken probably reflect technological …
