SoS 216: Claire Gold - Breastfeeding, Menarche, and Consequences

Chris checks in with Dr. Adam Johnson to discuss javelinas and their impact on humans. Dr. Johnson is an environmental anthropologist whose current work engages human-animal relations. His current project explores human-javelina relations in Texas, including affective relationships between javelinas and property owners, tourist-javelina encounters at Big Bend National Park, and the intimacy and care that pairs with violence in hunting. Previous research includes social boundary policing in a Drag Queen community in rural North Carolina, time budgeting and allocation in captive chimpanzees (at the North Carolina Zoo), female social relationships in rhesus macaques (Ocala National Forest, Florida), and science, racism, and inequality. ------------------------------ Contact Dr. Johnson: Website: anthropology365.com, E-mail: [email protected] ------------------------------ Contact the Sausage of Science Podcast and Human Biology Association: Facebook: facebook.com/groups/humanbiologyassociation/, Website: humbio.org, Twitter: @HumBioAssoc Chris Lynn, Host Website: cdlynn.people.ua.edu/, E-mail: [email protected], Twitter:@Chris_Ly Cristina Gildee, HBA Junior Fellow, SoS Producer Website: cristinagildee.org, E-mail: [email protected], Twitter:@CristinaGildee

The SoS Team puts one of their own in the hot seat as Courtney and Cristina interview Dr. Christopher Lynn about his book Transcendental Medication: The Evolution of Mind, Culture, and Healing. His book offers a unique perspective on why human brains evolved to have consciousness, yet we spend much of our time trying to reduce our awareness. It outlines how limiting consciousness—rather than expanding it—is more functional and satisfying for most people, most of the time. He suggests that our brains evolved mechanisms to deal with the stress of awareness in concert with awareness itself—otherwise, it is too costly to handle. Defining dissociation as “partitioning of awareness,” Dr. Lynn touches on disparate cultural and psychological practices such as religion, drug use, 12-step programs, and dancing. The chapters draw on biological and cultural studies of Pentecostal speaking in tongues and stress, the results of our 800,000+ years watching hearth and campfires, and unconscious uses of self-deception as a mating strategy, providing practical insights into our daily lives. As a professor of Anthropology at the University of Alabama, Dr. Lynn's research explores critical intersections between culture and health. His work also includes investigating the relationship between tattooing practices, known as tatau, and immune response among Samoans to understand how cultural practices may influence physiological responses. Dr. Lynn is also the executive producer and co-host of the Inking of Immunity podcast. ------------------------------ Find the book discussed in this episode: Transcendental Medication Lynn, C. D.

Special guest hosts Cristina and Miguel Ochoa unpack the nutritional ecology with Dr. Hugo Azcorra-Pérez, a human biologist at Centro de Investigaciones Silvio Zavala, Universidad Modelo, Mérida, Yucatán, Mexico. He is interested in the biology of populations during the early stages of growth and development and how environmental factors and intergenerational influences shape biological conditions. Born in Yucatán, México, he holds a Master of Sciences in Human Ecology and a Ph.D. in Human Biology (Loughborough University, UK). His research focuses on human growth and its variation according to economic and sociocultural variables. In his Ph.D. work, he assessed how intergenerational factors influence Maya families' development and nutritional status, particularly the phenomenon of nutritional dual-burden (i.e., the coexistence of undernutrition and overweight within the same family or individual). These interests have continued through his current work, which focuses on how the chronic adverse living conditions experienced by Maya populations from Yucatan have impacted their biology and health outcomes. ------------------------------ Find the paper discussed in this episode: Azcorra, H., Castillo-Burguete, M.

Chris and Courtney host Claire Gold, a Ph.D. candidate in the Department of Anthropology at The University of Massachusetts, Amherst, where she studies the life histories and diet of the women and children from a Medieval Italian population. Claire received her MA in Biological Anthropology from the State University of New York, Binghamton, where she focused on the reproductive correlates of reproductive cancers. Since then, she has raised three children with her husband. In 2019, Claire decided to pursue her PhD at 45 to continue contributing to relevant research on women's and children’s health. She is interested in early life events in modern humans and archaeological populations. Claire is a member of the Society for American Archaeology, the American Association of Biological Anthropologists, the Human Biology Association, the American Investigative Society of Cold Cases, and the International Society for Evolution, Medicine, and Public Health. ------------------------------ Find the works discussed in this episode: Gold, C.

Chris and Cristina interview Taiye Winful, a PhD Candidate at Vanderbilt University, who studies stress and embodiment in African and other Black populations. Taiye completed her bachelor's degree in Molecular Biology from Loyola University Chicago and MA degree in Anthropology from The University of North Carolina at Charlotte. Taiye’s Master’s thesis was titled “Reconstructing Africa’s Evolutionary Histories: DNA Collection, Coding, Analysis, and Interpretation.” Her thesis focused on generating a comprehensive bio-culturally informed set of African DNA databases that reflected continental and diasporic African genomic diversity. Taiye’s current research interests include genetics, race, health, embodiment, and health disparities. Her dissertation focuses on understanding how life experiences translate into physiological systems via stress in Black populations. She explores the biological mechanisms that connect stress and health, specifically focusing on how social and environmental factors can lead to epigenetic changes in inflammatory-related biomarkers. ------------------------------ Find the works discussed in this episode: Winful, Taiye, "Bioethics as a Dynamic Issue: Holistic Approaches to Understanding and Applying Ethics to Study Design" (2024).
