Dr Mansi Srivastava of Harvard University joins Chris and Courtney to talk about her research on regeneration throughout evolution. ----------------------------------------------------------------- Dr. Srivastava's research focuses on understanding the evolution of animal development and regeneration. Her group utilizes the three-banded panther worm, Hofstenia miamia, which Dr. Srivastava has developed as a new acoel model system. Acoels represent the sister-group to all animals with bilateral symmetry, which allows the study of genetic mechanisms that span 550 million years of animal evolution. Current projects in her lab range from identifying gene regulatory networks for regeneration to determining the embryonic origins of pluripotent stem cells to understanding the origins of bilaterian nervous systems. Her lab website can be found here: www.srivastavalab.org/ The following are citations for the articles mentioned on today’s show: Srivastava M. (2021).

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 m

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 conditi

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
