Associations Between Male Testosterone And Immune Function In A Pathogenically Stressed Forager-Horticultural Population, Benjamin C. Trumble, Aaron D. Blackwell, Jonathan Stieglitz, Melissa Emery Thompson, Ivan Maldonado Suarez, Hillard Kaplan, Michael Gurven
ESI Publications
Objectives—Despite well-known fitness advantages to males who produce and maintain high endogenous testosterone levels, such phenotypes may be costly if testosterone-mediated investment in reproductive effort trade-off against investment in somatic maintenance. Previous studies of androgen-mediated trade-offs in human immune function find mixed results, in part because most studies either focus on a few indicators of immunity, are confounded by phenotypic correlation, or are observational. Here the association between male endogenous testosterone and 13 circulating cytokines are examined before and after ex vivo antigen stimulation with phytohaemagglutinin (PHA) and lipopolysaccharides (LPS) in a high pathogen population of Bolivian forager-horticulturalists.

Women exhibit greater morbidity than men despite higher life expectancy. An evolutionary life history framework predicts that energy invested in reproduction trades-off against investments in maintenance and survival. Direct costs of reproduction may therefore contribute to higher morbidity, especially for women given their greater direct energetic contributions to reproduction. We explore multiple indicators of somatic condition among Tsimane forager-horticulturalist women (Total Fertility Rate = 9.1; n = 592 aged 15–44 years, n = 277 aged 45+). We test whether cumulative live births and the pace of reproduction are associated with nutritional status and immune function using longitudinal data spanning 10 …
Teaching: Natural Or Cultural?,

Teaching: Natural Or Cultural?, David F. Lancy
Sociology, Social Work and Anthropology Faculty Publications
In this chapter I argue that teaching, as we now understand the term, is historically and cross-culturally very rare. It appears to be unnecessary to transmit culture or to socialize children. Children are, on the other hand, primed by evolution to be avid observers, imitators, players and helpers—roles that reveal the profoundly autonomous and self-directed nature of culture acquisition (Lancy in press a). And yet, teaching is ubiquitous throughout the modern world—at least among the middle to upper class segment of the population. This ubiquity has led numerous scholars to argue for the universality and uniqueness of teaching as a …
High Resting Metabolic Rate Among Amazonian Forager-Horticulturalists Experiencing High Pathogen Burden,

High Resting Metabolic Rate Among Amazonian Forager-Horticulturalists Experiencing High Pathogen Burden, Michael Gurven, Benjamin C. Trumble, Jonathan Stieglitz, Gandhi Yetish, Daniel Cummings, Aaron D. Blackwell, Bret Beheim, Hillard Kaplan, Herman Pontzer
ESI Publications
Objectives—Resting metabolic rate (RMR) reflects energetic costs of homeostasis and accounts for 60-75% of total energy expenditure (TEE). Lean mass and physical activity account for much RMR variability, but the impact of prolonged immune activation from infection on human RMR is unclear in naturalistic settings. We evaluate the effects of infection on mass-corrected RMR among Bolivian forager-horticulturalists, and assess whether RMR declines more slowly with age than in hygienic sedentary populations, as might be expected if older adults experience high pathogen burden.
Materials and Methods—RMR was measured by indirect calorimetry (Fitmate MED, Cosmed) in 1,300 adults aged 20-90 …

Objectives
Archaeological dental calculus is a rich source of host‐associated biomolecules. Importantly, however, dental calculus is more accurately described as a calcified microbial biofilm than a host tissue. As such, concerns regarding destructive analysis of human remains may not apply as strongly to dental calculus, opening the possibility of obtaining human health and ancestry information from dental calculus in cases where destructive analysis of conventional skeletal remains is not permitted. Here we investigate the preservation of human mitochondrial DNA (mtDNA) in archaeological dental calculus and its potential for full mitochondrial genome (mitogenome) reconstruction in maternal lineage ancestry analysis.

Background—Amazonian populations are exposed to diverse parasites and pathogens, including protozoal, bacterial, fungal, and helminthic infections. Yet much of our understanding of the immune system is based on industrialised populations where these infections are relatively rare.
Aim—We examine distributions and age-related differences in 22 measures of immune function for Bolivian forager-horticulturalists and US and European populations.
Subjects and Methods—Subjects were 6,338 Tsimane aged 0–90 years. Blood samples collected between 2004–2014 were analysed for 5-part blood differentials, C-reactive protein, erythrocyte sedimentation rate (ESR), and total immunoglobulins E, G, A, and M. Flow cytometry was used to quantify naive …

Recreating Richard Iii: The Power Of Tudor Propaganda, Heather Alexander
Undergraduate Honors Theses
Because it signified the violent transition from the Plantagenet to Tudor dynasty, the death of King Richard III at the Battle of Bosworth’s Field was a monumental event. After five centuries, his skeleton was rediscovered by an archaeological team at a site, formerly the location of the Greyfriars Priory Church. The presentation uses the forensic evidence to examine the extent to which the perceived image of Richard III is the result of Tudor propaganda.

A Gnawing Problem: Does Rodent Incisor Microwear Record Diet Or Habitat?, Salvatore Samuel Caporale
Graduate Theses and Dissertations
Dental microwear has been shown to reflect food preferences and habitat in extant vertebrates, and its analysis has been applied to fossil assemblages to infer paleodiet and paleoenvironment. Such reconstructions are, of course, only as good as the extant baseline used to infer relationships between wear pattern and diet/habitat. This study tests, through dental microwear texture analysis, the potential of modern rodent lower incisors to reveal those relationships, and evaluates the extent to which effects of diet and habitat can be parsed from the signal. Microwear texture profiles were created for individual lower rodent incisors (n=430) using confocal profilometry and …

The Impact Of Mycobacterium Leprae: A Comprehensive Meta-Analysis Of The Paleopathological Literature, Mallory Alexis Schreier
Boise State University Theses and Dissertations
Leprosy, caused by the bacteria Mycobacterium leprae and Mycobacterium lepromatosis, is a chronic, infectious disease that eventually causes disfiguring skin lesions, nerve damage, and muscle weakness. Even though leprosy has been nearly eliminated in many parts of the world today, it remains endemic in India, Myanmar, Nepal, Brazil, and a few African countries. Unfortunately, this infectious disease is not limited to just modern populations. In the past, leprosy spread globally and was a pervasive, degenerating disease. The literature traces leprosy back to 1550 BCE although there is possible skeletal evidence of leprosy in Rajasthan, India from 2000 BCE, suggesting …

Reading Between The Lines: Indicators Of Developmental Stress In Prehistoric Ohio Valley Children From Linear Enamel Hypoplasias, Emily Moes
Boise State University Theses and Dissertations
A large body of research in bioarchaeology focuses on the changes in the human skeleton associated with the introduction of agriculture. It is assumed that the intensification of agriculture results in an increase in physiological stress and poor health. However, previous studies have shown that stress experiences cannot be generalized by subsistence strategy and prevalence comparisons alone. Rather, age-at and duration of stress events are necessary to construct patterns of health.
Linear enamel hypoplasias (LEH) of subadult permanent dentition serve as a proxy for understanding health and stress in archaeological populations. LEH are defects in enamel, characterized by an increased …

The use of global positioning systems (GPS) and mapping software are commonplace in today’s archaeology. Artifacts and human remains can be plotted on maps and digitized immediately on sites allowing for instant analysis. Yet, the use of GPS in some locations may not be feasible due to natural or human-made terrain features such as canopy cover, densely built urban environments, caves, or other environments where satellite access may be limited. Additionally, prior to the widespread use of GPS, field archaeologists had to rely solely upon systematic, detailed notes and sketches. Such was the case at the Bronze Age tomb at …

The study of the archaeological remains of fossil hominins must rely on reconstructions to elucidate the behaviour that may have resulted in particular stone tools and their accumulation. Comparatively, stone tool use among living primates has illuminated behaviours that are also amenable to archaeological examination, permitting direct observations of the behaviour leading to artefacts and their assemblages to be incorporated. Here, we describe newly discovered stone tool-use behaviour and stone accumulation sites in wild chimpanzees reminiscent of human cairns. In addition to data from 17 mid- to long-term chimpanzee research sites, we sampled a further 34 Pan troglodytes communities. We …

Climate, Ecology, And Human Evolution During The Plio-Pleistocene, Scott Adam Blumenthal
Dissertations, Theses, and Capstone Projects
A major goal of paleoanthropology is to identify the selective pressures associated with hominin biological and behavioral evolution, yet establishing cause-effect relationships between climate, ecology, and human evolution remains problematic. This dissertation seeks to investigate hominin paleoecology in eastern Africa by reconstructing aspects of climate and ecology using stable isotope analysis.
The first part of this dissertation is focused on the ecology of primates and hominins. Modern tropical African ecosystems provide a useful model for understanding the ecological correlates of isotopic variation in the fossil record, and living primates provide a useful model for understanding the ecological significance of isotopic …

Limiting The Impact Of Destructive Analytical Techniques Through Sequential Microspatial Sampling Of The Enamel From Single Teeth, Alexis E. Dolphin, Mathew A. Teeter, Christine D. White, Fred J. Longstaffe

A fundamental research concern within contemporary bioarchaeology is the sensitive balance between the preservation of human remains and the use of destructive techniques to collect information. Here we describe one example of how multiple microspatial destructive/semi-destructive techniques may be carried out in sequence using only the enamel of a single tooth. With careful planning of both sample preparation strategies and sequencing of sampling methods, it is possible to produce multiple datasets, and yet to retain material for future analyses.
In this case, enamel from the teeth of 27 individuals who lived during the early medieval period (AD 1170-1198) in Bergen, …

Playing With Knives: The Socialization Of Self-Initiated Learners, David F. Lancy
Sociology, Social Work and Anthropology Faculty Publications
Since Margaret Mead’s field studies in the South Pacific a century ago, there has been the tacit understanding that as culture varies, so too must the socialization of children to become competent culture users and bearers. More recently, the work of anthropologists has been mined to find broader patterns that may be common to childhood across a range of societies. One improbable commonality has been the tolerance, even encouragement, of toddler behavior that is patently risky, such as playing with or attempting to use a sharp-edged tool. This laissez faire approach to socialization follows from a reliance on children as …

South American camelids (llamas and alpacas) were of great economic, social and ritual significance in the pre-Hispanic Andes. Although these animals are largely limited to high-altitude (>3500 masl) pastures, it has been hypothesised that camelids were also raised at lower altitudes in the arid coastal river valleys. Previous isotopic studies of Early Intermediate Period (c. 200 BC - AD 600) and Middle Horizon (c. AD 600 - 1100) camelids support this argument. Here, we utilise carbon and nitrogen isotopic analyses of camelid bone collagen from the Early Horizon (c. 800 - 200 BC) sites of Caylán and Huambacho on …
