Christopher Bae is taking us on a journey to meet the hominids of Asia's past. Dr. Bae is a distinguished paleoanthropologist from the University of Hawai'i at Mānoa whose research focuses on human evolution in East Asia. Born in Korea and adopted by an American family, his unique personal journey sparked an early interest in race, human variation, and the deep history of our species. What began as a search for his own roots led him to a career dedicated to reconstructing the past—much like paleoanthropologists do when piecing together humanity's evolutionary story. Dr. Bae has conducted extensive field and laboratory research across Korea, Japan, and China, collaborating on projects that span hominin fossils, vertebrate taphonomy, and lithic analysis. His work bridges disciplines in the social and natural sciences, providing a comprehensive perspective on Pleistocene hominin morphological and behavioral variation, particularly in Homo erectus and both archaic and modern Homo sapiens. With approximately 150 publications and over $1.5 million in extramural funding, Dr. Bae is a leading voice in understanding human evolution in East Asia. ------------------------------ Find the papers discussed in this episode: Bae, C.

Bio Chris and Cristina interview Agustín Fuentes about his new book, Sex Is a Spectrum: The Biological Limits of the Binary (now available). Prof. Fuentes is an anthropologist whose research focuses on the biosocial, delving into the entanglement of biological systems with the social and cultural lives of humans, our ancestors, and a few of the other animals with whom humanity shares close relations. From chasing monkeys in jungles and cities, to exploring the lives of our evolutionary ancestors, to examining human health, behavior, and diversity across the globe, Professor Fuentes is interested in both the big questions and the small details of what makes humans and our close relations tick. Earning his BA/BS in Anthropology and Zoology and his MA and PhD in Anthropology from UC Berkeley, he has conducted research across four continents, multiple species, and two million years of human history. His current projects include exploring cooperation, creativity, and belief in human evolution, multispecies anthropologies, evolutionary theory and processes, and engaging race and racism. Fuentes is an active public scientist, a well-known blogger, lecturer, tweeter, and an explorer for National Geographic. Fuentes was recently awarded the Inaugural Communication & Outreach Award from the American Association of Biological Anthropologists, the President's Award from the American Anthropological Association, and elected to the American Academy of Arts and Sciences. Dr. Fuentes previously appeared in episodes 48 & 85 in which he shared his origin story & read an excerpt from a previous book. ------------------------------ Find the Books discussed in this episode: Fuentes, A.

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.

Gregoricka is a Professor of Anthropology in the Department of Sociology, Anthropology, & Social Work at the University of South Alabama. She also serves as Director of the USA Forensic Science Program. She received her B.A. from the University of Notre Dame and her M.A. and Ph.D. from The Ohio State University. Dr. Gregoricka uses biogeochemical techniques to examine changing patterns of human mobility, mortuary practices, paleo diet, and social complexity in the Near East, Arabia, and beyond. Her primary research program investigates prehistoric mortuary landscapes across the United Arab Emirates and Oman, seeking to evaluate how shifting mortuary traditions in southeastern Arabia reflect corresponding changes in sociopolitical complexity and subsistence strategies. From this, she explores how local identity was reinforced and negotiated through the construction of monumental tombs and treatment of the dead. Dr. Gregoricka's interest in embodied social identity has also taken her to Poland, where she worked with skeletons buried at the post-medieval cemetery at Drawsko as part of the Slavia Project. The Drawsko cemetery is well-known for its deviant burials, and her research focuses on the radiogenic and stable isotope analysis of the skeletal tissues of those interred as “vampires” to better discern why certain individuals were selected for apotropaic burial rites when others were not. Today, Dr. Gregoricka co-directs the NSF-REU Site: Bioarchaeology of Bronze Age Social Systems, which brings undergraduate students from across the country to USA each summer to learn to conduct bioarchaeological research. She is also currently involved with research on the movements of pastoralist groups in ancient Nubia. ------------------------------------------------------------- Contact the Sausage of Science Podcast and Human Biology Association: Facebook: www.facebook.com/groups/humanbiologyassociation Website: humbio.org/, Twitter: @HumBioAssoc Chris Lynn, HBA Public Relations Committee Chair Website: cdlynn.people.ua.edu/, E-mail: cdlynn at ua.edu, Twitter:@Chris_Ly Eric Griffith, HBA Junior Fellow, SoS producer E-mail: eric.griffith at duke.edu

Cara and guest co-host Cristina sit down with Dr. Chris Kuzawa, the John D. MacArthur Professor & Faculty Fellow at the Institute for Policy Research at Northwestern University. He uses principles from anthropology and evolutionary biology to gain insights into the biological and health impacts of human developmental plasticity. His primary field research is conducted in Cebu, the Philippines, where he and his colleagues work with a large birth cohort study that enrolled more than 3,000 pregnant women in 1983 and has since followed their offspring into adulthood (now 30 years old). They use the nearly 3 decades of data available for each study participant, and recruitment of generation 3 (the grand offspring of the original mothers), to gain a better understanding of the long-term and intergenerational impacts of early life environments on adult biology, life history, reproduction, and health. A theme of much of his work is the application of principles of developmental plasticity and evolutionary biology to issues of health. ------------------------------ Contact Chris: kuzawa@northwestern.edu Website: https://sites.northwestern.edu/kuzawa/; Twitter:@ChrisKuzawa ------------------------------ Contact the Sausage of Science Podcast and Human Biology Association: Facebook: facebook.com/groups/humanbiologyassociation/, Website: humbio.org, Twitter: @HumBioAssoc Cara Ocobock, HBA Public Relations Committee Chair, Cara Ocobock, Co-Host, Website: sites.nd.edu/cara-ocobock/, Email:cocobock@nd.edu, Twitter: @CaraOcobock Cristina Gildee, HBA Junior Fellow, SoS producer Website: cristinagildee.org, E-mail: cgildee@uw.edu, Twitter: @CristinaGildee

Twice the Caras! Cara and Cristina interview Dr. Cara Wall-Scheffler, professor and co-chair of Biology at Seattle Pacific University and an affiliate professor in the Department of Anthropology at the University of Washington. Her research focuses on the evolution of human sexual dimorphism, particularly in the context of balancing the pressures of thermoregulation and long-distance locomotion. She has been working on this problem for over 20 years. Her work demonstrates that different selection pressures have acted on men and women and that women, in particular, have a rare (among mammals) ability to work both efficiently (energy per unit of mass) and economically (total energy) when carrying loads. Women's abilities are partly due to their relatively small body size, relatively high surface area, relatively broader pelves, and unique methods of thermoregulation. In addition to her research, Dr. Wall-Scheffler teaches courses in human physiology and evolutionary mechanisms on campus and at the Blakely Island Field Station.

Season 6 premiere. Cara's back! Chris and Cara chat with Dr. Saige Kelmelis, a biological anthropologist specializing in bioarchaeology, paleodemography, paleoepidemiology, and forensic anthropology. Her research involves the study of human skeletal and dental remains to reconstruct aspects of life, health, disease, identity, and demography. She integrates methods and theory in osteology, paleodemography, epidemiology, and hazard analyses to explore the interplay between human biocultural behavior and infectious disease. She also uses methods from bioarchaeology to reconstruct life histories and health outcomes in modern and past populations through cementochronology. Kelmelis is also a primary investigator on a collaborative project with other professionals, students, and tattoo artists in South Dakota to understand how this ancient practice of body modification affects health outcomes in modern people. Current and ongoing research includes the exploration of mortality risk and disease in monastic, urban, and rural medieval Denmark, the application of cementochronology to reconstruct modern human life histories in Bangladesh, paleodemographic and life history reconstruction of the ancient Maya in the Upper Belize Valley, advancing statistical models in paleodemography, and the short- and long-term impacts of tattooing and body modification on health in past and present populations.
