Modern humans have more fragile skeletons than other hominins, which may result from physical inactivity. Here, we test whether reproductive effort also compromises bone strength, by measuring using computed tomography thoracic vertebral bone mineral density (BMD) and fracture prevalence among physically active Tsimane forager-horticulturalists. Earlier onset of reproduction and shorter interbirth intervals are associated with reduced BMD for women. Tsimane BMD is lower versus Americans, but only for women, contrary to simple predictions relying on inactivity to explain skeletal fragility. Minimal BMD differences exist between Tsimane and American men, suggesting that systemic factors other than fertility (e.g. diet) do not …


The Dynamics Of Men's Cooperation And Social Status In A Small-Scale Society, Christopher Von Rueden, Daniel Redhead, Rick O'Gorman, Hillard Kaplan, Michael Gurven Aug 2019

The Dynamics Of Men's Cooperation And Social Status In A Small-Scale Society, Christopher Von Rueden, Daniel Redhead, Rick O'Gorman, Hillard Kaplan, Michael Gurven

We propose that networks of cooperation and allocation of social status co-emerge in human groups. We substantiate this hypothesis with one of the first longitudinal studies of cooperation in a preindustrial society, spanning 8 years. Using longitudinal social network analysis of cooperation among men, we find large effects of kinship, reciprocity and transitivity in the nomination of cooperation partners over time. Independent of these effects, we show that (i) higher-status individuals gain more cooperation partners, and (ii) individuals gain status by cooperating with individuals of higher status than themselves. We posit that human hierarchies are more egalitarian relative to other …

A hypothesis for the evolution of long post-reproductive lifespans in the human lineage involves asymmetries in relatedness between young immigrant females and the older females in their new groups. In these circumstances, inter-generational reproductive conflicts between younger and older females are predicted to resolve in favor of the younger females, who realize fewer inclusive fitness benefits from ceding reproduction to others. This conceptual model anticipates that immigrants to a community initially have few kin ties to others in the group, gradually showing greater relatedness to group members as they have descendants who remain with them in the group. We examine …


The Anatomy Of Patriotism: The Commodification Of American Gender Roles And The Female Body In World War Ii Print Media, Adison Beals Jun 2019

The Anatomy Of Patriotism: The Commodification Of American Gender Roles And The Female Body In World War Ii Print Media, Adison Beals

Voces Novae

During World War II, the United States turned to the female gender roles that underpinned American society and commodified them in print media to sell the war effort and female participation in it, resulting in the appearance of hands, lips, and legs in propaganda, makeup advertisements, and pinup images. This phenomenon reflects how physical presentation indicates social anxieties and American constructions of gender, as well as how the female body is imbued with cultural symbolism.


Rediscovering Brazil: The Marajoara Style In Modernist Art And Design, Alyson Brandes May 2019

Rediscovering Brazil: The Marajoara Style In Modernist Art And Design, Alyson Brandes

Student Scholar Symposium Abstracts and Posters

During the Portuguese rule of Dom Pedro II until 1889, through the years of the First Brazilian Republic (1889-1930) and into the First Vargas Regime (1930-1945), Brazil struggled to solidify a strong national identity that would finally unify the country and legitimize its rich cultural heritage. The discovery and excavation of Marajó Island in the 1870s provided evidence of a great, ancient civilization, and inspired Brazilian Art Deco and early Modernist artists. Polychrome ceramic urns, vessels, and tangas (female pubic covers) were among the most abundant archaeological finds, many with zoomorphic and geometric motifs that show the cultural importance of …


Asian American Representation On Social Media Platforms, Ashley Lee May 2019

Asian American Representation On Social Media Platforms, Ashley Lee

Student Scholar Symposium Abstracts and Posters

YouTube is a popular social media platform where anyone can make an account and post any kind of content. When YouTube launched in 2005-06, it has since allowed minorities easier access to create stories in an industry that has a history of exclusion and whitewashing, specifically speaking about Asian Americans. Asian American content creators, such as Wong Fu Productions, Michelle Phan, Ryan Higa, and many others use YouTube as an outlet to adapt existing stereotypes into entertainment while resisting whitewashing in Hollywood. By analyzing their large influence online, we try to better understand who consists of their target audience, either …


The Formation Of Queer Consciousness In Gay, Latin, Men: How Experiences Affect The Lives Of Queer Latinos, Daniel Leon-Barranco May 2019

The Formation Of Queer Consciousness In Gay, Latin, Men: How Experiences Affect The Lives Of Queer Latinos, Daniel Leon-Barranco

Student Scholar Symposium Abstracts and Posters

I am interested in investigating the question: How does experience, in a Latinx environment, affect the “coming out” process for queer, Latinx, men? Additionally, the aim of this research is to discover whether Queer Latinx peoples retain their cultural identity/consciousness or abandon it. This project is relevant to analyze whether Latinx culture impacts peoples to abstain from or retain their cultural identity/consciousness. I also hope that this research can prove whether an amalgamation of standpoint theory and Situated Knowledge can come together to affect the process of (re)claiming identity; as the Latinx man claims their sexual identity. This research aims …

"The recent reframing of the Visual Anthropology section in American Anthropologist was motivated by a sense that new technologies have democratizing power and that through multimodal forms we can address a shift toward engagement and collaboration in anthropological research (Collins, Durington, and Gill 2017). Our purpose in this essay is to engage and expand the discussion raised by Samuel Collins, Matthew Durington, and Harjant Gill in their 2017 article 'Multimodal Anthropology: An Invitation,' which has been widely cited and has helped to inspire a range of new projects in anthropology that do not prioritize text. Although the idea of multimodal …
