#552 Kate Adamala: Synthetic Cells, Cell Evolution, the Origin of Life, and Astrobiology

Nov 25, 2021

Dr. Katarzyna (Kate) P. Adamala is a synthetic biologist and a professor of genetics at the University of Minnesota. Dr. Adamala's work includes contributions to the field of astrobiology, synthetic cell engineering, and biocomputing. Her research on prebiotic RNA replication provided an experimental scenario for the RNA world hypothesis of the origin of life. She has worked on constructing liposome bioreactor synthetic cells. She is a founder and steering group member of the Build-a-Cell Initiative, an international collaboration for creation of synthetic live cells. She is a co-founder of synthetic cell company Synlife. Adamala and Szostak demonstrated non enzymatic RNA replication in primitive protocells is only possibly in presence of weak cation chelator like citric acid, providing further evidence for the central role of citric acid in primordial metabolism.

#537 Christopher Kuzawa: Developmental Plasticity, Life History, and Epigenetics

Oct 21, 2021

Dr. Christopher Kuzawa is Professor of Anthropology and 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 works 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). He uses the nearly 3 decades of data available for each study participant, and recruitment of generation 3 (the grandoffspring 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. More»

#530 Jeremy DeSilva - A Most Interesting Problem; Darwin’s Descent of Man (150th anniversary)

Oct 4, 2021

Dr. Jeremy DeSilva is an Associate Professor of Anthropology at Dartmouth College. He is a paleoanthropologist, specializing in the locomotion of the first apes (hominoids) and early human ancestors (hominins). His particular anatomical expertise-- the human foot and ankle-- has contributed to our understanding of the origins and evolution of upright walking in the human lineage. He has studied wild chimpanzees in Western Uganda and early human fossils in Museums throughout Eastern and South Africa. From 1998-2003, Dr. DeSilva worked as an educator at the Boston Museum of Science and continues to be passionate about science education. He is the author of A Most Interesting Problem: What Darwin’s Descent of Man Got Right and Wrong about Human Evolution. More»
#518 Andrew Berry: The History of Evolutionary Biology (Pt. 2) - Genetics, and Speciation

Sep 6, 2021

Dr. Andrew Berry is a lecturer in Organismic and Evolutionary Biology. He is an evolutionary biologist with a particular interest in Alfred Russel Wallace. His research combined field and laboratory methods to detect positive Darwinian selection (i.e. adaptive evolution) at the molecular level in natural populations. He has published two books: Infinite tropics: an Alfred Russel Wallace Anthology, with a foreword written by Stephen Jay Gould, and DNA: The Secret of Life with James Watson. More»
#517 James Costa: Darwin, Wallace, The Origin of Species, and The Descent of Man (150th anniversary)

Sep 3, 2021

Dr. James Costa is Executive Director of the Highlands Biological Station and Professor of Evolutionary Biology at Western Carolina University, where he has taught courses in genetics, entomology, evolution, and biogeography since 1996. His many interests include insect behavior and ecology, environmental history and philosophy, conservation biology, and the history of science. His research has focused in recent years on Charles Darwin, Alfred Russel Wallace, and the history of evolutionary thought. He has authored numerous research papers, reviews, magazine articles, and 7 books, including Darwin's Backyard: How Small Experiments Led to a Big Theory (W. W. Norton, 2017) — a finalist for the American Association for the Advancement of Science/Subaru Prize — and the co-edited volume An Alfred Russel Wallace Companion (Chicago, 2019). More»
