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.

Host Courtney Manthey unpack the obstetric dilemma with Dr. Anna G. Warrener. Dr. Anna G. Warrener earned her PhD from Washington University in St. Louis in 2012. She is now an assistant professor of anthropology at the University of Colorado Denver. She specializes in human evolutionary biology, biomechanics, and the evolution of locomotion. Her research explores how skeletal morphology influences movement, with a particular focus on the biomechanics of the pelvis, gait, and bipedal efficiency. Through experimental and comparative approaches, Dr. Warrener investigates how evolutionary pressures have shaped human locomotion and what these adaptations reveal about our ancestors. She is also passionate about mentoring students and fostering interdisciplinary research that bridges anthropology, biology, and biomechanics. ------------------------------ Find the paper discussed in this episode: Warrener, A.

Chris and Cristina chat with Dr. Ian Wallace, an Assistant Professor of Anthropology at the University of New Mexico, where he is the director of the Human Physical Activity Lab. As an Evolutionary Anthropologist, Ian's work focuses on how humans evolved to use their bodies and explores the costs and benefits of modern physical activity patterns for our health. He is particularly interested in populations transitioning from non-industrial to industrial and post-industrial contexts. Ian earned his Ph.D. in Anthropology in 2013 from Stony Brook University, where his dissertation examined how physical activity and genetics determine limb bone structure. Following graduate school and an initial postdoctoral position at Stony Brook, he completed his postdoctoral training in the Department of Human Evolutionary Biology at Harvard and started his own lab at UNM. There, he focuses on measures of locomotor biomechanics and their ties to the health and function of the musculoskeletal system. Recently, his fieldwork has focused on the Indigenous peoples of Peninsular Malaysia. In particular, he is interested in how their lifestyles are changing with the rapid expansion of industries, the market economy, and urban areas across Malaysia, as well as how these changes affect their health and risk of disease. ------------------------------ Find the papers discussed in this episode: Wallace, I.

Dr. Amato is a biological anthropologist studying the influence of gut microbes on host ecology and evolution. Her research examines how changes in the gut microbiota impact host nutrition, energetics, and health. She uses non-human primates as models for studying host-gut microbe interactions in selective environments and for providing comparative insight into the evolution of the human gut microbiota. Her main foci are understanding how the gut microbiome may buffer hosts during periods of nutritional stress and how the gut microbiome programs normal inter-specific differences in host metabolism. In this realm, she is also interested in global variation in the human gut microbiome and its implications for local human adaptation. Dr. Amato obtained her A.B. in Biology from Dartmouth College and her Ph.D. in Ecology, Evolution and Conservation Biology from the University of Illinois at Urbana-Champaign. She completed a postdoc at the University of Colorado Boulder. She joined the Department of Anthropology in 2015. She is also affiliated with the Interdisciplinary Biological Sciences Graduate Program and sits on the Executive Committee of the Northwestern Institute on Complex Systems. Dr. Amato is the President of the Midwest Primate Interest Group, an Associate Editor at Microbiome, an Editorial Board member at Folia Primatologica, and a Fellow for the Canadian Institute of Advanced Research’s ‘Humans and the Microbiome’ Program. ------------------------------ Find the paper discussed in this episode: Mallott, E., Kuthyar, S., Lee, W., … & Amato, K.

Dr Anna Marie Prentiss joins Host Chris Lynn to discuss the origins of institutionalised inequality. Anna is an archaeologist specializing in the ancient history of the Great Plains, Pacific Northwest, and Arctic regions of North America. She has a methodological specialty in lithic technology and theoretical interests in the archaeology of villages and towns, social inequality, hunter-gatherer mobility and technological organization, and the cultural evolutionary process. She is associate editor of the scholarly journal, Current Anthropology. Dr. Prentiss is actively engaged in a long term study of the evolution of complex hunter-gatherer-fisher societies on the interior of British Columbia. The current focus of this research is a multi-year excavation at the Bridge River archaeological site, located near the town of Lillooet, British Columbia. With funding from the National Science Foundation, Dr. Prentiss, along with her students and colleagues conducted major excavations during 2008 and 2009 to examine socio-economic and political changes that occurred during the occupation span of the village. Recent research (2012-2023) at Bridge River has been funded by the National Endowment for the Humanities and the National Science Foundation. ------------------------------ Find the paper discussed in this episode: Prentiss, A.
