Podcast appearances and mentions of chris kuzawa

Chris and Courtney sit down with Dr. Haley Ragsdale to discuss intergenerational signals of matrilineal experience. Haley completed her dissertation in Anthropology at Northwestern University in 2023 under the guidance of Dr. Chris Kuzawa. She is now a postdoctoral researcher in the Anthropology Department at the University of Illinois Chicago, collaborating with Dr. Katie Starkweather on fascinating projects related to maternal and child health among the Shodagor of Bangladesh. Haley's work is deeply rooted in evolutionary theory and the developmental origins of health and disease (DOHaD) framework, with a focus on human reproductive biology. She explores how energetic experiences shape lifetime metabolic strategies and how reproductive investments are influenced by varying environmental contexts. Currently, she's diving into the mechanisms behind intergenerational signals of matrilineal experience and predictive adaptive responses in humans. ------------------------------ Find the paper discussed in this episode: Ragsdale, H.

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

This symposium brings together scientists representing evolutionary biology, genetics, dermatology, anthropology, and physiology to share their knowledge and questions about human skin in an explicitly evolutionary framework. UC San Diego’s Rob Knight begins with a discussion about Ecology and Evolution of the Skin Microbiome, followed by Mark Stoneking on Of Lice and Men: The Molecular Evolution of Human Lice, and Chris Kuzawa on Subcutaneous Fat in Humans. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Health and Medicine] [Science] [Show ID: 30207]

In this talk, Chris Kuzawa (Northwestern Uni) argues that human body fat co-evolved not just with the energetically-demanding and vulnerable brain, but also with the cultural strategies that humans use to buffer offspring intake. The human infant’s need for ample baby fat traces to the fact that the main causes of nutritional stress at this age are infections, which force a reliance on onboard energy by reducing appetite and impairing digestion. However, by early childhood, we are less reliant upon this resource as a result of another uniquely human buffering system: food sharing and our cooperative strategy of caring for and feeding our young.

The Health Inequality Network (HINet) is a multidisciplinary research network comprising a group of world-class scholars on health research from diverse fields. HINET's aim is to synthesize and extend insights from several disciplines into a unified approach and comprehensive framework for understanding the emergence and evolution of health disparities over the lifecycle and across generations. This effort will incorporate the study of socioeconomic determinants, genetic inheritance, epigenetic mechanisms, and biological and neuronal pathways, as well as behavioral responses and policy interventions.
