What if animal sounds are not just signals, but music, performance, and meaning?In this wide-ranging conversation, philosopher and musician David Rothenberg and animal cognition researcher and writer Justin Gregg explore the strange borderlands between music, language, animal communication, play, science, and imagination. Moving from birdsong and whale music to dolphins, narwhals, emotional support alligators, escaped zoo animals, and improv comedy, they ask what happens when we stop treating animals as biological machines and start listening to them as expressive beings.David Rothenberg, professor of philosophy and music at the New Jersey Institute of Technology, has spent decades making music with birds, whales, insects, and other species while writing about the philosophical and scientific meaning of animal sound. Justin Gregg, author of If Nietzsche Were a Narwhal and Humanish, studies animal minds, dolphin cognition, and the ways humans project meaning onto other creatures. Together, they bring music, science, philosophy, humor, and curiosity into a lively conversation about what animals know, what humans imagine, and why the boundary between the two is never as clean as we think.They discuss why birds sing, whether animal sounds can be understood as music, how scientists study communication without reducing it to simple function, and why anthropomorphism is not always the mistake it is assumed to be. The conversation opens into stories of beluga whales, military dolphins, narwhals, prairie dogs, koalas, lyrebirds, emotional support alligators, animal escape stories, and the deep human need to find kinship with other beings.TIMESTAMPS00:00:57 – David Rothenberg on music, philosophy, and his unconventional academic path00:04:35 – Justin Gregg on sociolinguistics, dolphins, and entering animal cognition from the humanities00:05:20 – Scott McVay, John Lilly, Gregory Bateson, and the strange history of dolphin research00:07:45 – Teaching electronic music to engineering students and encouraging creative play00:12:21 – What makes sound music, and why streaming has changed how people listen00:20:04 – Organized sound, John Cage, silence, and listening differently00:24:08 – Why birds sing at dawn and why science still struggles to explain the dawn chorus00:26:34 – Birdsong, mating success, nightingales, and the limits of simple evolutionary explanations00:29:16 – Studying musicality in birds and why scientists resisted the question00:34:20 – Humpback whale song, beauty, and what science often leaves out00:39:15 – Koalas, lyrebirds, noise, distortion, and what humans recognize as song00:44:10 – Bee dances, prairie dogs, symbolic communication, and the importance of attention00:48:05 – Justin Gregg’s emotional support alligator story and animals as individuals00:53:55 – Narwhals, belugas, military dolphins, and Cold War animal research00:57:10 – Escaped animals, freedom stories, and why humans root for animals in captivityGUESTSJustin Gregg – Animal Cognition Researcher and WriterAuthor of If Nietzsche Were a Narwhal, Humanish, and Are Dolphins Really Smart?

Waste is not just what societies discard. It is one of the clearest records of who we are, how we live, and what kind of planet we are leaving behind. In this wide-ranging conversation, anthropologist Joshua Reno and geologist Jan Zalasiewicz explore waste as both a human problem and a geological force, moving from landfills and urban rubble to deep time, the Anthropocene, and the far future of Earth itself.  Joshua Reno, professor of anthropology at Binghamton University, studies the hidden systems societies depend on but prefer not to think about, especially landfills, disposal, and the cultural meanings of waste. Jan Zalasiewicz, geologist and paleontologist, has spent decades mapping the physical traces humans leave behind, from landfill strata and made ground to the broader geological signatures of the Anthropocene. Together, they bring two very different disciplines into unusually close conversation. They discuss why waste is both necessary and disavowed, how landfills reveal uncomfortable truths about human behavior, and why the geological scale of human leftovers is far larger than most people realize. They explore how cities preserve layers of industrial history like buried archives, why “waste as resource” is both useful and misleading, and how the accelerating production of waste changes our sense of time. From there, the conversation opens outward into questions of continuity, extinction, future readers, nuclear warning systems, the Fermi paradox, deep-time oceans, and what it means to leave a material record in a universe that may not care whether anyone is left to interpret it.   This conversation bridges anthropology, geology, environmental thought, philosophy, and deep time, revealing waste not as a side effect of civilization, but as one of its defining signatures.⸻TIMESTAMPS00:00:27 – Joshua Reno on landfills, hidden systems, and the paradox of necessary waste00:06:27 – Why studying trash reveals more than self-reporting ever can00:10:06 – Why many geologists resist treating landfill and waste as geology00:13:22 – The shocking scale of the technosphere and humanity’s waste legacy00:19:03 – Why pollution narratives are powerful but incomplete00:20:55 – Fly ash, landfill mining, and the complicated idea of “good waste”00:25:43 – Cities as layered archives: London, war, rubble, and urban strata00:29:23 – What landfill work feels like from the inside: constant motion, danger, and routine00:35:34 – Sewer epidemiology and why institutions often resist what waste can reveal00:39:00 – Future readers, lost continuity, and who might one day interpret our remains00:49:08 – Nihilism, speculative philosophy, and the spread of “the world after us” thinking00:53:12 – The Fermi paradox and whether civilizations accelerate into self-destruction01:00:35 – Nuclear waste, deep burial, and the problem of warning distant futures    ⸻GUESTSJoshua Reno – Professor of Anthropology, Binghamton UniversityAuthor of Waste Away: Working and Living with a North American Landfill and Military Waste: The Unexpected Consequences of Permanent War Readiness.

Cultural evolution has shaped human nature far more than we realize, and economist Robin Hanson and evolutionary biologist Joe Henrich reveal why ignoring this changes everything about policy, innovation, and our future. In this deep dive conversation, they explore how culture doesn't just influence behavior, it rewrites our preferences, beliefs, and even our cognitive machinery.

Joe Henrich, professor at Harvard and author of The WEIRDest People in the World, explains how humans evolved to be uniquely reliant on social learning, making us a cultural species first and foremost. Robin Hanson, economist at George Mason University and author of The Elephant in the Brain, challenges the implications: if cultural evolution can account for most of human nature, then far more has changed in the last hundred thousand years than conventional wisdom suggests—and far more could change in the near future.

Together, they tackle why economists bracket preferences instead of explaining them, how WEIRD psychology has dominated research while studying statistical outliers, why the collective brain hypothesis suggests innovation depends more on population size than individual genius, and why organizations systematically suppress innovation despite claiming to value it. They discuss marriage norms and kinship structures that literally reshape cognition across cultures, big gods and moral religions that enabled large-scale cooperation, and the uncomfortable selection pressures modern societies refuse to discuss openly.

This conversation bridges economics, evolutionary biology, anthropology, and policy—revealing why cultural evolution deserves far more attention than it receives in academia, government, and institutional design.⸻
