Chris and Eric catch up with Dr. Melanie Martin, an Associate Professor in the University of Washington Department of Anthropology, whose research examines biocultural influences on health, growth, and development across the life course. In addition to being the Co-PI of the Biodemography Lab at the University of Washington Center for Studies in Demography and Ecology, she conducts field research with two international projects on Indigenous community health and well-being: the Chaco Area Reproductive Ecology Program (Co-Director) and the Tsimane Health and Life History Project (Affiliate). In this episode, Dr. Martin breaks down two of her papers, one looking at COVID-19 transmission in mothers and infants and another examining sleep health in undergraduates before and during the COVID-19 pandemic. ------------------------------ Find the papers discussed in this episode: Martin MA, Keith M, Pace RM, Williams JE, Ley SH, Barbosa-Leiker C, Caffé B, Smith CB, Kunkle A, Lackey KA, Navarrete AD, Pace CDW, Gogel AC, Eisenberg DTA, Fehrenkamp BD, McGuire MA, McGuire MK, Meehan CL and Brindle E (2022) SARS-CoV-2 specific antibody trajectories in mothers and infants over two months following maternal infection.

His work focuses on chronic diseases of aging, working to understand how environmental conditions like parasites, pathogens, food availability, and social interactions impact human health. Taking an evolutionary life history perspective, he uses field and laboratory studies to understand variation in human endocrine systems, and how this influences chronic health conditions like benign prostatic hyperplasia, cardiovascular disease, and Alzheimer’s dementia.

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

Chris and special guest co-host Courtney Manthey-Peirce interview Dimitris Xygalatas, author of Ritual: How Seemingly Senseless Acts Make Life Worth Living. Associate Professor in Anthropology and Psychological Sciences at the University of Connecticut and head of the Experimental Anthropology Lab, Dimitris is an anthropologist and cognitive scientist who studies some things that make us human – but not the obvious ones. He is interested in some of the more peculiar aspects of human nature: ritual, music, sports fanship, and other things that help people connect, cope, and live meaningful lives. Dimitris’ research combines experimental methods with ethnographic fieldwork to study human culture holistically over the last several years in Southern Europe and Mauritius. ------------------------------ Contact Dimitris: xygalatas@uconn.edu Website: xygalatas.com; Twitter: @xygalatas ------------------------------ Contact the Sausage of Science Podcast and Human Biology Association: Facebook: facebook.com/groups/humanbiologyassociation/, Website: humbio.org, Twitter: @HumBioAssoc Chris Lynn, HBA Public Relations Committee Chair, Website: cdlynn.people.ua.edu/, E-mail: cdlynn@ua.edu, Twitter:@Chris_Ly Courtney Manthey-Peirce, Guest-Co-Host, Website: courtneymanthey-pierce.godaddysites.com/ E-mail: cpierce4@uccs.edu, Twitter: @HolyLaetoli Cristina Gildee, SoS producer Website: cristinagildee.org, E-mail: cgildee@uw.edu, Twitter:@CristinaGildee

He investigates depression, suicide, and deliberate self-harm as potential signaling strategies. Child growth and development is a research theme that grew out of his work on postpartum depression. Prof. Hagen also recently begun testing evolutionary models of leadership and knowledge specialization as part of my more general interest in the evolution of human social organization. Finally, he has published a number of theoretical papers on evolutionary approaches to ontogeny, cognition, and behavior.
