#1081 - Bret Weinstein & Heather Heying

Bret Weinstein is an American evolutionary biologist, podcaster, and author specializing in adaptive trade-offs and the application of evolutionary principles to contemporary societal challenges. Born on February 21, 1969, he earned a PhD in biology from the University of Michigan, where his dissertation examined evolutionary trade-off mechanisms in biological systems. Weinstein served as a professor of biology at The Evergreen State College from 2002 until his resignation in 2017, following widespread campus protests triggered by his email objection to a proposed change in the school's Day of Absence tradition that would have asked white students and faculty to leave campus voluntarily. The controversy, which involved student disruptions of his classes and demands for his resignation, highlighted tensions over institutional equity policies and free speech on campus, leading Weinstein and his wife, fellow biologist Heather Heying, to depart amid safety concerns and a subsequent lawsuit against the college alleging a hostile work environment. Since then, Weinstein has co-hosted the DarkHorse Podcast , discussing topics from evolutionary theory to critiques of public health responses during the COVID-19 pandemic, and co-authored A Hunter-Gatherer's Guide to the 21st Century: Evolution and the Challenges of Modern Life (2021), which applies evolutionary frameworks to modern human behavior and technology. His work emphasizes empirical scrutiny of orthodoxies in science and culture, often positioning him as a skeptic of prevailing institutional narratives. Bret Weinstein was born on February 21, 1969, in Los Angeles, California. He grew up in Southern California as part of a Jewish family. Weinstein has an older brother, Eric Weinstein, a mathematician, economist, and managing director at Thiel Capital. His parents, described by Weinstein as good people and lifelong Democrats, reside in Los Angeles. Little public information exists regarding his parents' professions or specific details of his early home environment, though Weinstein has noted celebrating Hanukkah with his own children despite personal non-belief in God, suggesting a cultural continuity of Jewish traditions from his upbringing. Weinstein began his undergraduate studies at the University of Pennsylvania before transferring to the University of California, Santa Cruz, where he earned a Bachelor of Arts degree in biology. He then pursued graduate work at the University of Michigan, completing a PhD in biology in 2009 with a dissertation titled Evolutionary Trade-Offs: Emergent Constraints and the Adaptive Landscape , which examined mechanisms of evolutionary trade-offs in biological systems. His doctoral research contributed to understanding constraints on adaptation, drawing on quantitative models of senescence, species diversity, and ecological dynamics. During his time at Michigan, Weinstein received the Don Tinkle Award for distinguished work in evolutionary ecology, recognizing excellence in research and scholarship within the department. His primary graduate mentor was evolutionary biologist Richard D. Alexander, whose work on eusociality, kin selection, and the evolution of cooperation influenced Weinstein's focus on multilevel selection processes and trade-offs in organismal fitness. Weinstein's academic training emphasized empirical and theoretical approaches to evolutionary biology, including field observations and mathematical modeling of adaptive constraints, shaping his later applications of evolutionary principles to human behavior, morality, and societal dynamics. This foundation aligned with classical evolutionary theorists like W.D. Hamilton and Robert Trivers, whose ideas on inclusive fitness and reciprocal altruism informed his dissertation's exploration of emergent biological constraints.

Heather Heying is an American evolutionary biologist, author, and podcaster who specializes in applying evolutionary theory to analyze human behavior and modern societal challenges. She earned a PhD in Biology from the University of Michigan, receiving the university's top dissertation honor, and a B.A. in Anthropology from the University of California, Santa Cruz. Heying's research has focused on the evolution of social systems and sexual selection, examining species from frogs to humans, with fieldwork in areas such as tropical biology and herpetology. For 15 years, she served as a professor of biology at The Evergreen State College, where she taught undergraduates using an evolutionary framework until resigning in 2017 following violent campus protests sparked by her objection to inverting the college's traditional Day of Absence event, which had previously encouraged non-white students and faculty to participate in off-campus activities. After leaving Evergreen, Heying held a Visiting Fellowship at Princeton University from 2019 to 2021 and co-authored A Hunter-Gatherer's Guide to the 21st Century (2021) with her husband, evolutionary biologist Bret Weinstein, offering an evolutionary perspective on issues including diet, parenting, and technology. She co-hosts the DarkHorse Podcast , which explores scientific and cultural topics through an evolutionary lens, and publishes the Substack newsletter Natural Selections on related themes. Heather Heying was born on April 26, 1969, in Santa Monica, California, and grew up in Los Angeles. She attended high school in Los Angeles during the 1980s. Heying has described her early life as involving residences along the West Coast of the United States, reflecting a peripatetic upbringing before extended time in Michigan during graduate studies. Heying pursued undergraduate studies in anthropology at the University of California, Santa Cruz, earning a B.A. in 1992 with college honors. Her senior thesis, advised by evolutionary biologist Robert Trivers and physical anthropologist Adrienne Zihlman, examined "Measures of Attractiveness Among Old World Monkeys: How Unrelated Females Choose Their Friends," focusing on social selection and female choice in primate groups. This work laid foundational interests in evolutionary ecology and animal behavior, bridging anthropology and biology. She then advanced to graduate training at the University of Michigan, Ann Arbor, where she obtained a Ph.D. in Biology in 2001. Advised by herpetologist Arnold Kluge, her dissertation, "The Evolutionary Ecology and Sexual Selection of a Madagascan Poison Frog (Mantella laevigata)," earned the university's Distinguished Dissertation Award and involved field research on amphibian mating systems and sexual dimorphism in a biodiversity hotspot. This training emphasized empirical fieldwork, phylogenetic analysis, and evolutionary theory applied to reproductive strategies, shaping her subsequent research on social insects and human behavioral evolution. Following receipt of her Ph.D. in Biology from the University of Michigan in 2001, where her dissertation on evolutionary trade-offs in amphibian social systems earned the university's Distinguished Dissertation Award under advisor Arnold Kluge, Heying transitioned into early professional contributions in biological documentation and education. Her research emphasized evolutionary ecology, including prior graduate-level field studies on conservation impacts to dart-poison frogs ( Dendrobatidae ) in Sarapiquí, Costa Rica, from 1994 to 1995, which informed her post-doctoral scholarly output. From 2001 to 2002, Heying served as a contributor to the Animal Diversity Web (ADW), an online database hosted by the University of Michigan Museum of Zoology that compiles peer-reviewed entries on animal taxonomy, morphology, ecology, and behavior for educational purposes.
