Natural Sleep And Its Seasonal Variations In Three Pre-Industrial Societies, Gandhi Yetish, Hillard Kaplan, Michael Gurven, Brian Wood, Herman Pontzer, Paul R. Manger, Charles Wilson, Ronald Mcgregor, Jerome M. Siegel Nov 2015

Natural Sleep And Its Seasonal Variations In Three Pre-Industrial Societies, Gandhi Yetish, Hillard Kaplan, Michael Gurven, Brian Wood, Herman Pontzer, Paul R. Manger, Charles Wilson, Ronald Mcgregor, Jerome M. Siegel

ESI Publications

How did humans sleep before the modern era? Because the tools to measure sleep under natural conditions were developed long after the invention of the electric devices suspected of delaying and reducing sleep, we investigated sleep in three preindustrial societies[1–3]. We find that all three show similar sleep organization, suggesting that they express core human sleep patterns, likely characteristic of pre-modern era Homo sapiens. Sleep periods, the times from onset to offset, averaged 6.9–8.5-h, with sleep durations of 5.7–7.1-h, amounts near the low end of those industrial societies[4–7]. There was a difference of nearly 1-h between summer and winter sleep. …

Calcaneal Quantitative Ultrasound Indicates Reduced Bone Status Among Physically Active Adult Forager-Horticulturalists, Jonathan Stieglitz, Felicia C. Madimenos, Hillard Kaplan, Michael Gurven Oct 2015

Calcaneal Quantitative Ultrasound Indicates Reduced Bone Status Among Physically Active Adult Forager-Horticulturalists, Jonathan Stieglitz, Felicia C. Madimenos, Hillard Kaplan, Michael Gurven

ESI Publications

Six months of exclusive breastfeeding (EBF) is considered optimal for infant health, though globally most infants begin complementary feeding (CF) earlier—including among populations that practice prolonged breastfeeding. Two frameworks for understanding patterns of early CF emerge in the literature. In the first, maternal and infant needs trade-off, as “maternal-centric” factors—related to time and energy demands, reproductive investment, cultural influences, and structural barriers— favor supplanting breastfeeding with earlier and increased CF. A second framework considers that “infant-centric” factors—related to infant energetic needs—favor CF before six months to supplement breastfeeding.

We apply these two frameworks in examining early CF among the Tsimane—a …


Exploring Cape Malay Identity Through The Lens Of Food, Allyson Ang Oct 2015

Exploring Cape Malay Identity Through The Lens Of Food, Allyson Ang

Independent Study Project (ISP) Collection

This study explores the construction of Cape Malay identity through the lens of food. Made up of descendants of slaves from India, Madagascar, Indonesia, Malaysia, Mozambique, and other places, “Cape Malay” is a very contentious identity. Although people who fall under the label of Cape Malay today are hundreds of years removed from their slave ancestors, there are still distinct remnants of these origins in Cape Malay culture. One of the ways in which this is most evident is Cape Malay cuisine. Cape Malay dishes such as bobotie, samosas, bredie, and beryani have become staples in South African …


Does Market Integration Buffer Risk, Erode Traditional Sharing Practices And Increase Inequality? A Test Among Bolivian Forager-Farmers, Michael Gurven, Adrian V. Jaeggi, Christopher Von Rueden, Paul L. Hooper, Hillard Kaplan Jul 2015

Does Market Integration Buffer Risk, Erode Traditional Sharing Practices And Increase Inequality? A Test Among Bolivian Forager-Farmers, Michael Gurven, Adrian V. Jaeggi, Christopher Von Rueden, Paul L. Hooper, Hillard Kaplan

ESI Publications

Sharing and exchange are common practices for minimizing food insecurity in rural populations. The advent of markets and monetization in egalitarian indigenous populations presents an alternative means of managing risk, with the potential impact of eroding traditional networks. We test whether market involvement buffers several types of risk and reduces traditional sharing behavior among Tsimane Amerindians of the Bolivian Amazon. Results vary based on type of market integration and scale of analysis (household vs. village), consistent with the notion that local culture and ecology shape risk management strategies. Greater wealth and income were unassociated with the reliance on others for …


Depression As Sickness Behavior? A Test Of The Host Defense Hypothesis In A High Pathogen Population, Jonathan Stieglitz, Benjamin C. Trumble, Melissa Emery Thompson, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven Jun 2015

Depression As Sickness Behavior? A Test Of The Host Defense Hypothesis In A High Pathogen Population, Jonathan Stieglitz, Benjamin C. Trumble, Melissa Emery Thompson, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven

ESI Publications

Sadness is an emotion universally recognized across cultures, suggesting it plays an important functional role in regulating human behavior. Numerous adaptive explanations of persistent sadness interfering with daily functioning (hereafter “depression”) have been proposed, but most do not explain frequent bidirectional associations between depression and greater immune activation. Here we test several predictions of the host defense hypothesis, which posits that depression is part of a broader coordinated evolved response to infection or tissue injury (i.e. “sickness behavior”) that promotes energy conservation and reallocation to facilitate immune activation. In a high pathogen population of lean and relatively egalitarian Bolivian foragerhorticulturalists, …


Life History Theory And School-Age Pregnancy: Review And Application, Anna Rozman May 2015

Life History Theory And School-Age Pregnancy: Review And Application, Anna Rozman

Honors Scholar Theses

The United States currently holds one of the highest teenage pregnancy rates in the developed world, but many Americans, including policy makers, view adolescent childbearing as a societal problem that stems from negligence, promiscuity, and poor decision making. This project seeks to frame the institution of school-age motherhood through the lens of Life History Theory, which posits that early reproduction is an adaptation in the face of harsh conditions and high extrinsic mortality rates. This assertion is supported by evidence that adolescent childbearing has been the norm for most of human history, and continues to be practiced in natural fertility …

Education, Crystal C. Gray

Eddie Mabry Diversity Award

Education is a spoken word poem that explores many aspects of the African American struggle within (self-knowledge). It starts with an African American college student who is disappointed with the lack of courses about her culture. Most curricula in the United States tend to be from a Eurocentric perspective, leaving out a multitude of information about people of color. All groups of people of color have unique experiences, however, African Americans have the most known (or perhaps I should say, unknown) history. The standard explanation of their existence is often limited to the start of the Trans-Atlantic Slave Trade, when …

Language As The Foundation Of Identity Among Sherpa Youth In Nepal, Joshua H. Ginder Apr 2015

Language As The Foundation Of Identity Among Sherpa Youth In Nepal, Joshua H. Ginder

Student Publications

This paper explores how young Sherpas in Nepal use their language as a tool for identifying themselves as uniquely Sherpa in a mutlicultural Nepal. By analyzing the way Sherpas use their language in social settings and at a radio station, the author suggests the Sherpa language is perhaps the only truly unique quality that delineates Sherpas from other Nepalis.


Inclusive Fitness And Differential Productivity Across The Life Course Determine Intergenerational Transfers In A Small-Scale Human Society, Paul L. Hooper, Michael Gurven, Jeffrey Winking, Hillard Kaplan Mar 2015

Inclusive Fitness And Differential Productivity Across The Life Course Determine Intergenerational Transfers In A Small-Scale Human Society, Paul L. Hooper, Michael Gurven, Jeffrey Winking, Hillard Kaplan

ESI Publications

Transfers of resources between generations are an essential element in current models of human life-history evolution accounting for prolonged development, extended lifespan and menopause. Integrating these models with Hamilton’s theory of inclusive fitness, we predict that the interaction of biological kinship with the age-schedule of resource production should be a key driver of intergenerational transfers. In the empirical case of Tsimane’ forager–horticulturalists in Bolivian Amazonia, we provide a detailed characterization of net transfers of food according to age, sex, kinship and the net need of donors and recipients. We show that parents, grandparents and siblings provide significant net downward transfers …

Low Mineral Density Of A Weight-Bearing Bone Among Adult Women In A High Fertility Population, Jonathan Stieglitz, Bret Beheim, Benjamin C. Trumble, Felicia C. Madimenos, Hillard Kaplan, Michael Gurven Dec 2014

Low Mineral Density Of A Weight-Bearing Bone Among Adult Women In A High Fertility Population, Jonathan Stieglitz, Bret Beheim, Benjamin C. Trumble, Felicia C. Madimenos, Hillard Kaplan, Michael Gurven

ESI Publications

Evolutionary theories of aging posit that greater reproductive effort causes somatic decline given a fundamental trade-off between investing energy in reproduction and repair. Few studies in high fertility human populations support this hypothesis, and problems of phenotypic correlation can obscure the expected trade-off between reproduction and somatic condition. This cross-sectional study investigates whether greater reproductive effort is associated with reduced calcaneal bone mineral density (BMD) among female Tsimane forager-farmers of lowland Bolivia. We also investigate whether female Tsimane BMD values are lower than sex- and age-matched US reference values, despite the fact that Tsimane engage in higher physical activity levels …

Did One Veil Give Women A Better Life?, Mary C. Westermann Oct 2014

Did One Veil Give Women A Better Life?, Mary C. Westermann

Student Publications

Unfortunately, a young woman in Renaissance Florence did not have many options for her future. A woman's family usually decided whether she would be able to get married or would have to enter the convent, but sometimes she was able to make this choice. In this paper, I look at the lives of wives and nuns to analyze how their lives differed in responsibilities and freedoms, but also to see how all women had similar restrictions and expectations placed upon them.


"My People Is A People On Its Knees": Mexican Labor Migration From The Montana Region And The Formation Of A Working Class In New York City, Rodolfo Hernandez-Corchado Oct 2014

"My People Is A People On Its Knees": Mexican Labor Migration From The Montana Region And The Formation Of A Working Class In New York City, Rodolfo Hernandez-Corchado

Dissertations, Theses, and Capstone Projects

This dissertation examines the contemporary proletarianization via migration of the indigenous and mestizo people from the Montaña region, in the Mexican southern state of Guerrero, to New York City. The dissertation demonstrates how the region was transformed since the 1980s into a migrant labor supplier and how its inhabitants became proletarians, and a major pool of labor supplying the North American transnational migrant labor market.

Far from being homogenous, the people of the Montaña region are ethnically and class diverse. Based on the oral narratives of an indigenous Mixteco, and a mestizo teenager dweller of the city of Tlapa, the …


Leadership In An Egalitarian Society, Christopher Von Rueden, Michael Gurven, Hillard Kaplan, Jonathan Stieglitz Sep 2014

Leadership In An Egalitarian Society, Christopher Von Rueden, Michael Gurven, Hillard Kaplan, Jonathan Stieglitz

ESI Publications

Leadership is instrumental to resolution of collective action dilemmas, particularly in large, heterogeneous groups. Less is known about the characteristics or effectiveness of leadership in small-scale, homogeneous, and relatively egalitarian societies, in which humans have spent most of our existence. Among Tsimane’ forager-horticulturalists of Bolivia, we (1) assess traits of elected leaders under experimental and naturalistic conditions and (2) test whether leaders impact collective action outcomes. We find that elected leaders are physically strong and have more kin and other exchange partners. Their ranks on physical dominance, kin support, and trustworthiness predict how well their groups perform, but only where …


Political Influence Associates With Cortisol And Health Among Egalitarian Forager-Farmers, Christopher Von Rueden, Benjamin C. Trumble, Melissa Emery Thompson, Jonathan Stieglitz, Paul L. Hooper, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven Sep 2014

Political Influence Associates With Cortisol And Health Among Egalitarian Forager-Farmers, Christopher Von Rueden, Benjamin C. Trumble, Melissa Emery Thompson, Jonathan Stieglitz, Paul L. Hooper, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven

ESI Publications

Background and objectives: Low social status increases risk of disease due, in part, to the psychosocial stress that accompanies feeling subordinate or poor. Previous studies report that chronic stress and chronically elevated cortisol can impair cardiovascular and immune function. We test whether lower status is more benign in small-scale, relatively egalitarian societies, where leaders lack coercive authority and there is minimal material wealth to contest.

Methodology: Among Tsimane’ forager-horticulturalists of lowland Bolivia, we compare informal political influence among men with urinary cortisol, immune activation (innate and acquired), and morbidity as assessed during routine medical exams.

Results: After …

Fernand Braudel popularized the longue durée approach to scholarly investigation in the mid-20th century. The longue durée approach can be loosely translated to mean “look for the big picture, synthesize data collected using all available methodology over the long periods of time to identify fundamental principles, rather than becoming preoccupied with isolated observations.” Braudel, a historian and economist, emphasized observation of enduring historical structures and analysis of long-term, panoramic economic trends rather than concentrating on detailed descriptions of particular events or individuals. He also urged the use of insight gained from many scholarly disciplines to identify the essential underpinnings of …

Paleogenetics offers a unique opportunity to study human evolution, population dynamics, and disease evolution in situ. Although histologic and computed x-ray tomographic investigations of ancient mummies have clearly shown that atherosclerosis has been present in humans for more than 5,000 years, limited data are available on the presence of genetic predisposition for cardiovascular disease in ancient human populations. In a previous whole-genome study of the Tyrolean Iceman, a 5,300-year-old glacier mummy from the Alps, an increased risk for coronary heart disease was detected. The Iceman’s genome revealed several single nucleotide polymorphisms that are linked with cardiovascular disease in genome-wide association …

Computed tomographic findings of atherosclerosis in the ancient cultures of Egypt, Peru, the American Southwest and the Aleutian Islands challenge our understanding of the fundamental causes of atherosclerosis. Could these findings be true? Is so, what traditional risk factors might be present in these cultures that could explain this apparent paradox? The recent computed tomographic findings are consistent with multiple autopsy studies dating as far back as 1852 that demonstrate calcific atherosclerosis in ancient Egyptians and Peruvians. A nontraditional cause of atherosclerosis that could explain this burden of atherosclerosis is the microbial and parasitic inflammatory burden likely to be present …

Background: Evidence of atherosclerotic plaques in ancient populations has led to the reconsideration of risk factors for heart disease and of the common belief that it is a disease of modern times.

Methods: Fifty-one wrapped mummy bundles excavated from the sites of Huallamarca, Pedreros, and Rinconada La Molina from the Puruchuco Museum collection in Lima, Peru, were scanned using computed tomography to investigate the presence of atherosclerosis. Funerary artifacts contained within the undisturbed mummy bundles were analyzed as an attempt to infer the social status of the individuals to correlate social status with evidence of heart disease in …

The Music And Multiple Identities Of Kurdish Alevis From Turkey In Germany, Ozan Aksoy Feb 2014

The Music And Multiple Identities Of Kurdish Alevis From Turkey In Germany, Ozan Aksoy

Dissertations, Theses, and Capstone Projects

This dissertation investigates the experiences of Kurdish Alevis, currently living in Germany, who trace their background to locations within the boundaries of the Republic of Turkey. I argue that music has been a particularly important mode through which Kurdish Alevis in Germany have articulated collective histories and have fashioned narratives of belonging and multiple and sometimes contradictory identities. The subjects of my research are immigrants and refugees who are ethnically Kurdish and whose religion is Alevi, an Anatolian religion whose relations to both Sunni and Shi'a Islam are historically controversial. They speak Turkish along with Kurdish, in most cases are …


The Evolutionary Fitness Of Personality Traits In A Small-Scale Subsistence Society, Michael Gurven, Christopher Von Rueden, Jonathan Stieglitz, Hillard Kaplan, Daniel Eid Rodriguez Jan 2014

The Evolutionary Fitness Of Personality Traits In A Small-Scale Subsistence Society, Michael Gurven, Christopher Von Rueden, Jonathan Stieglitz, Hillard Kaplan, Daniel Eid Rodriguez

ESI Publications

"Personality, or “behavioral syndromes”, are relatively stable dispositional traits and behaviors that have now been identified in a myriad of social species (Gosling, 2001; Sih et al., 2004), and with clear consequences on fitness (Smith & Blumstein, 2008). The canalization of personality during development and relative stability thereafter, despite varying circumstances over the life course that might otherwise favor greater plasticity, is an important problem attracting much theoretical and empirical attention (Dall et al., 2004; Dingemanse et al., 2010). Further, personality is highly heritable, yet how heritable genetic variation in personality traits is maintained over generations remains another conundrum (Buss …

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

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 …
