In this episode, Dr. Theodore Schurr shares insights from his career researching genetic prehistories, linkages, and identities within transforming geopolitical landscapes of the past as well as contemporary sociopolitical shifts, including post-Soviet Russia and Georgia. Next, Dr. Schurr and hosts Cara and Chris reflect on the evolution of anthropology and genetic research, including breakthrough technologies and advanced field methods, changing bioethics, intentional relationships with communities, and exciting new approaches that are expanding our understanding of variation and genetic-environmental interactions of the past and present. Dr. Theodore (Tad) Schurr is a Professor in the Department of Anthropology and the Director of the Laboratory of Molecular Anthropology at the University of Pennsylvania. For over thirty years, he has investigated the genetic prehistory of Asia and the Americas through studies of mtDNA, Y-chromosome, and autosomal DNA variation in Asian, Siberian, and Native American populations. For these studies, his lab characterized genetic diversity in indigenous populations of Canada, the United States, Mexico, and the Caribbean. His research group is currently exploring the population history of Georgia (Caucasus), Pakistan, Kazakhstan, and Polynesia through collaborative studies in those regions. Other projects have investigated the role of the mtDNA in adaptation, cancer, complex diseases, and metabolism. ------------------------------ Find the papers discussed in this episode: Yardumian, A., Shengelia, R., Chitanava, D., Laliashvili, S., Bitadze, L., Laliashvili, I., ... & Schurr, T.

In this episode, we talk with Dr. Kyle Wiley, Assistant Professor of Sociology & Anthropology at the University of Texas at El Paso, about how social and traumatic stressors during pregnancy become biologically embedded and shape maternal and infant health. Kyle shares his path into biological anthropology and discusses his biosocial research on perinatal health disparities in the United States and Brazil. We explore his work on interpersonal violence during pregnancy in São Paulo, Brazil, focusing on how trauma affects maternal and infant cortisol regulation and what this means for fetal programming and intergenerational health. We also discuss his recent research on pica among Latina pregnant women, which takes a novel approach by examining stress hormones and inflammation rather than micronutrient deficiencies. The episode closes with a look at Kyle’s new faculty role at UTEP, his current projects, and how he maintains work–life balance as an early-career scholar. ------------------------------ Find the work discussed in this episode: Wiley, K.

In this episode, hosts Chris and Mecca interview Dr. Cindi SturtzSreetharan about language decoding, why inclusive language matters for better science, the importance of clearly defining the terms we use, and how ethnographic methods help contextualize research. Dr. SturtzSreetharan is a President’s Professor at the School of Human Evolution & Social Change at Arizona State University. She has a bachelor’s degree in international relations from Willamette University, a master’s in Asian studies from the University of Oregon, and a doctorate in Anthropology from the University of California at Davis. Her research interests center on a language-in-interaction approach to the construction of identities, including masculinity. Much of her earlier work focused on how Japanese men use language as a resource for creating, maintaining, or refuting a masculine identity. She has also worked on language use in reality TV shows, serial dramas, and film, focusing specifically on language and fatherhood. For the past decade, Dr. SturtzSreetharan has turned her attention to the intersection of language, the body, and medicine. Her current work is an investigation of metabolic syndrome in Japan, a so-called lifestyle condition that affects more men than women. She is particularly interested in the way that everyday, mundane language interactions contribute to the production of felt shame and stigma around body size, shape, and care. ------------------------------ Find the papers discussed in this episode: SturtzSreetharan, C.L & Shibamoto-Smith, J.

In this fun and “soupy” episode, hosts Cara and Chris chat with Dr. Melanie Beasley about putrefied meat, maggots, stable isotopes, and media attention at the most inconvenient times. Dr. Beasley directs the BioAnth Isotope Ecology Research Laboratory (BIER Lab) at Purdue University. Her work focuses broadly on human-environment interactions throughout the hominin lineage when the environment is influencing our evolutionary history, in the Holocene when humans are influencing the availability of prey resources, and in modern forensic contexts when the environment imprints meaningful geolocation information in biological tissues. She uses stable isotope geochemistry to connect humans and the environment they live in to understand changing climate, resource availability, and life history. The use of stable isotope geochemistry and the big data generated by such an analytical method in anthropology has only scratched the surface of what it can offer to the discipline and its contributions to humanity’s grand challenges. Through her scholarship, she sees the Anthropology of Tomorrow as an interdisciplinary blending of the social and natural sciences in an applied approach that makes anthropology relevant to living communities. Dr. Beasley is also interested in science communication to engage with the public about anthropology. Please contact her via email if you are interested in working in the lab as an undergraduate or for enquiries about graduate student training. Dr. Beasley is accepting applications for future MA/PhD students. ------------------------------ Find the paper discussed in this episode: Beasley, M. M., Lesnik, J. J., & Speth, J. D. (2025).

Cecilia Padilla Iglesias estudió Ciencias Humanas y de la Evolución en University College de Londres, donde empezó a interesarse por cómo surgió y cambió la diversidad cultural y biológica en nuestra especie. Hizo un máster en Antropología Evolutiva en Cambridge y luego un doctorado en la Universidad de Zúrich sobre cómo los cambios ecológicos y sociales han moldeado la dinámica de las poblaciones humanas. Durante el doctorado pasó varios meses en la República del Congo trabajando con comunidades nómadas de cazadores-recolectores. Hoy trabaja en Cambridge con una beca de investigación, estudiando cómo la vida nómada y la movilidad se reflejan en el genoma de estas poblaciones. La idea central de su trabajo es que la movilidad ha sido clave para la resiliencia de los humanos durante cientos de miles de años, y que fue lo que permitió adaptarse a enormes cambios ecológicos y demográficos en los diferentes ecosistemas que fue habitando. ------------------------------ Encuentra el trabajo comentado en este episodio: Padilla-Iglesias, C., Xue, Z., Leonardi, M., Paijmans, L.A,J., Colucci, M., … Manica, A.

Lawrence M. Schell is a Distinguished Professor in the Department of Anthropology and the College of Integrated Health Sciences at the University at Albany, SUNY, with a joint appointment in the Department of Epidemiology and Biostatistics. His research explores the interrelationship between biology and culture, with a particular focus on how contemporary urban environments shape human health and development. Dr. Schell’s early work examined noise as a form of urban stress, investigating its effects on prenatal and postnatal growth. He later expanded his research to include pollutants such as polychlorinated biphenyls (PCBs) and lead, situating these exposures within the broader context of urban adaptation and health disparities. The study of lead exposure in Albany, NY, examined its influence on child physical and cognitive development, with attention to maternal nutrition and other factors that affect the transfer of lead from mother to fetus. In partnership with the Akwesasne Mohawk Nation he has recently completed three major projects. The first examined how PCBs that were used in manufacturing affect physical and sexual development during adolescence. His second project followed up the adolescents in project 1 to learn how exposure had influenced their transition into adulthood. The third project, also conducted with the Akwesasne community, explored how environmental pollutants may impact reproductive health and fertility among women. Through this work, Dr. Schell highlights the urban environment as a critical frontier for human adaptation, emphasizing the challenges posed by pollution, stress, and other features of modern city life while recognizing that these challenges are inequitably distributed in society. In 2004 Schell established a research center at Albany with NIH support to grow research on health disparities. Continued NIH support culminated in an endowment grant that will support the center and the development of health disparities research for many years to come. ------------------------------ Contact the Sausage of Science Podcast and the Human Biology Association: Facebook: facebook.com/groups/humanbiologyassociation/, Website: humbio.org, Twitter: @HumBioAssoc Chris Lynn, Co-Host Website: cdlynn.people.ua.edu/, E-mail: cdlynn@ua.edu, Twitter:@Chris_Ly Courtney Manthey, Guest-Co-Host, Website: holylaetoli.com/ E-mail: cpierce4@uccs.edu, Twitter: @HolyLaetoli Anahi Ruderman, SoS Co-Producer, HBA Junior Fellow, E-mail: ruderman@cenpat-conicet.gob.ar

This week on The Sausage of Science, Chris and Cristina explore pica (the craving and consumption of nonfood items like earth or clay) through the lens of maternal health and nutrition. Our guest, Dr. Leila Larson of the University of South Carolina, shares insights from her study on pica among pregnant women in Malawi, part of the REVAMP iron supplementation trial. She discusses how iron status, infection, and environment influence maternal health, why intravenous iron may be a more effective approach to reducing pica, and what these cravings reveal about nutrition and development worldwide.

La doctora Isaura Cruz es bio-antropóloga y sus intereses de investigación se centran en la amplia contribución del medio ambiente a la salud y el bienestar humanos. Ha examinado el desarrollo de las condiciones cardiovasculares y metabólicas entre los indígenas mexicanos P'urépecha en sus comunidades de origen en Michoacán, México y las comunidades de acogida en Carolina del Norte, EE.UU. Isaura utiliza un enfoque de métodos mixtos que incluye elementos de la nutrición, la salud pública, la genómica, aplicando siempre una lente biocultural. La investigación de que la conversaremos hoy es parte de su trabajo de tesis doctoral, titulada “Migración Internacional y Salud: P’urépecha en EEUU y México”. En particular hablaremos de un estudio binacional que realizaron entre los años 2018 y 2019, sobre la salud cardiometabólica en la comunidad P’urépecha, un pueblo originario del estado de Michoacán, México. El estudio consiste en una comparación de los factores de riesgo de salud cardiometabólica (CHM) entre quienes viven en sus comunidades de origen en Michoacán, México, y quienes viven en Carolina del Norte, EE. UU. Este trabajo integra perspectivas y métodos de la antropología, la salud pública, la demografía y la sociología, entre otros, para comprender mejor la salud en el contexto de la migración internacional. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Dr. Isaura Cruz is a bioanthropologist whose research focuses on the environmental factors that contribute to human health and well-being. She has studied the development of cardiovascular and metabolic conditions among P'urhépecha indigenous Mexicans in their home communities in Michoacán, Mexico and in host communities in North Carolina, USA. Dr. Cruz uses a mixed-methods approach that incorporates nutrition, public health, and genomics while applying a biocultural lens. The research we will discuss today is part of her doctoral dissertation, entitled International Migration and Health: P'urhépecha in the US and Mexico." Specifically, we will discuss a binational study conducted between 2018 and 2019 examining cardiometabolic health in the P'urhépecha community, an indigenous group in the state of Michoacán, Mexico. This study compares cardiometabolic health risk factors between individuals residing in their home communities in Michoacán and those residing in North Carolina. This work integrates perspectives and methods from anthropology, public health, demography, sociology, and other fields to better understand health in the context of international migration. ------------------------------ Contact Dr. Cruz: igodinezcruz@scu.edu ------------------------------ Contact the Sausage of Science Podcast and Human Biology Association: Facebook: facebook.com/groups/humanbiologyassociation/, Website: humbio.org, Twitter: @HumBioAssoc Anahi Ruderman, SoS Co-Producer, HBA Junior Fellow E-mail: ruderman@cenpat-conicet.gob.ar Chris Lynn, Co-Host Website: cdlynn.people.ua.edu/, E-mail: cdlynn@ua.edu, Twitter:@Chris_Ly

In this episode, Chris and Cristina talk with Anamika Nanda, a PhD student in the Department of Biological Sciences and a Women in Science and Engineering (WiSE) Fellow at the University of Southern California. Anamika’s research, conducted under the guidance of Dr. David Raichlen, examines how physical activity affects neurological health across various genotypes. Before beginning her doctoral work, Anamika earned her Bachelor's degree in Medical Anthropology and Global Health from the University of Washington. Her award-winning honors thesis examined the relationship between motivation, physical activity, and psychosocial stress, and its impact on telomere length in collegiate swimmers and non-collegiate athletes. We discuss her path into science, her interdisciplinary approach to understanding brain health, and how her work connects athletics, stress, and aging. Anamika’s research has been recognized with an NSF-GRFP Honorable Mention, the UW Anthropology Department’s Best Honors Thesis Award, and a Mary Gates Research Scholarship. Tune in for an insightful conversation on the biology of movement, the value of interdisciplinary research, and what it means to study sports from a holistic perspective. ------------------------------ Find the paper discussed in this episode: Nanda, A., Logan, A., & Tennyson, R.

Emily is a PhD student and biological anthropologist at Northwestern University and a Student Representative for the Human Biology Association. She studies brain development from an evolutionary perspective, focusing on how early life stress shapes cognitive, behavioral, social, and physiological development. Her dissertation examines how early adversity and parenting influence executive function, learning, and memory, exploring potential adaptive outcomes of early stress. Emily is also pursuing research on brain energetics during development in early childhood and developing field-friendly methods to study brain energetics for anthropologists. She’s passionate about bringing ideas and methods from neuroscience into the field of anthropology to better understand what shapes human behavior and biology.
