  • The Vet at the End of the Earth: Adventures with Animals in the South Atlantic
    Mar 5 2026
    The role of a resident vet in the remote islands of the Falklands, St. Helena, Ascension, and Tristan da Cunha encompasses many wonderful complexities: caring for the world’s oldest living land animal (a 200-year-old giant tortoise, denizen of the St. Helena governor’s lawn); pursuing mystery creatures and invasive microorganisms; relocating herds of reindeer; and rescuing animals in extraordinarily rugged landscapes, from subtropical cloud forests to volcanic cliff faces. Dr. Hollins’s tales of island vet life are not only full of ingenuity and astounding fauna—they are also steeped in the unique local cultures, history, and peoples of the islands, far from the hustle of continental life. Our guest is: Dr. Jonathan Hollins, who graduated from Emmanuel College, Cambridge, and has been a working vet for four decades. Since the mid-2000s, he has spent long periods as a senior vet overseas in the South Atlantic. He has written for the British national press and presented documentary features for BBC Radio 3 and Radio 4. He lives on St. Helena. Our host is: Dr. Christina Gessler, who is an academic writing coach and editor. She is the producer and show host of the Academic Life podcast.

  • Robert Endres, "The Unreasonable Likelihood of Being: Origin of Life, Terraforming, and AI" (arXiv, 2025)
    Feb 24 2026
    In this episode we discuss the paper "The Unreasonable Likelihood of Being: Origin of Life, Terraforming, and AI" (arXiv, 2025) with Robert Endres. Paper Abstract: The origin of life on Earth via the spontaneous emergence of a protocell prior to Darwinian evolution remains a fundamental open question in physics and chemistry. Here, we develop a conceptual framework based on information theory and algorithmic complexity. Using estimates grounded in modern computational models, we evaluate the difficulty of assembling structured biological in-formation under plausible prebiotic conditions. Our results highlight the formidable entropic and informational barriers to forming a viable protocell within the available window of Earth’s early history. While the idea of Earth being terraformed by advanced extraterrestrials might violate Occam’s razor from within mainstream science, directed panspermia—originally proposed by Francis Crick and Leslie Orgel—remains a speculative but logically open alternative. Ultimately, uncovering physical principles for life’s spontaneous emergence remains a grand challenge for biological physics. Full paper available here Learn more about your ad choices.

  • Ellen Clarke, "The Units of Life: Kinds of Individual in Biology" (Oxford UP, 2025)
    Feb 10 2026
    While we tend to think of biological individuals in terms of paradigmic cases – a dog, a starfish, a bacterium – our ordinary criteria for distinguishing one individual from another are inadequate for making these distinctions in general. If a starfish can literally split itself in two and each half regenerates into a new starfish, why hold that there was just one starfish to begin with rather than many? In The Units of Life: Kinds of Individual in Biology (Oxford UP, 2025), Ellen Clarke defends the idea of evolutionary individuals: units created and maintained by mechanisms that ensure the parts share a common fate. Such individuals enable good evolutionary bookkeeping, in particular our ability to predict which variations in these individuals will enable natural selection to occur. Clarke, an associate professor of philosophy at the University of Leeds, considers the merits of her view in relation to alternatives, how her view explains the emergence of new levels of biological individuality, and how the need for idealization and scientific choice of individual boundaries can avoid conventionalism about biological individuals.

  • Daniel R. Langton, "Darwin in the Jewish Imagination: Jews' Engagement with Evolutionary Theory" (Oxford UP, 2026)
    Feb 10 2026
    In this episode, Rabbi Marc Katz sits down with Professor Daniel Langton, author of Darwin in the Jewish Imagination: Jews' Engagement with Evolutionary Theory (Oxford UP, 2026), to explore how Jewish thinkers responded to one of the most disruptive ideas of the modern world: evolutionary theory. Spanning a century of debate, the conversation traces how traditionalists, reformers, secular intellectuals, mystics, and philosophers reimagined Judaism in light of Darwin—from Europe to the United States. Rather than a simple science-versus-religion clash, Langton reveals a rich and creative dialogue shaped by modernity, Jewish-Christian relations, and a distinctive Jewish tendency toward pan(en)theistic thinking—understanding God as deeply intertwined with an evolving universe. Together, Katz and Langton explore how Darwin forced Jewish thinkers to rethink creation, divine action, and morality, and how those debates continue to shape modern Jewish belief and identity. Daniel Langton is Professor of Jewish Studies at the University of Manchester and a leading scholar of modern Jewish thought and Jewish-Christian relations. His work focuses on how Jews have engaged major intellectual movements of modernity, including science, philosophy, and theology. Rabbi Marc Katz is a congregational rabbi, author, and teacher whose work bridges classical Jewish texts and contemporary cultural questions. He is the author of Yochanan’s Gamble: Judaism’s Pragmatic Approach to Life and writes widely on Judaism, ethics, and modern life. Learn more about your ad choices. Visit megaphone.fm/adchoices

  • Oren Harman, "Metamorphosis: A Natural and Human History" (Basic Books, 2025)
    Feb 8 2026
    A search for the meaning of one of nature's greatest riddles: why do so many creatures transform? “How many creatures walking on this earth / Have their first being in another form?” the Roman poet Ovid asked two thousand years ago. He could not have known the full extent of the truth: today, biologists estimate a stunning three-quarters of all animal species on Earth undergo some form of metamorphosis.But why do tadpoles transform into frogs, caterpillars into butterflies, elvers into eels, immortal jellyfish from sea sprigs to medusae and back again, growing younger and younger in frigid ocean depths? Why must creatures go through massive destruction and remodeling to become who they are? Tracing a path from Aristotle to Darwin to cutting-edge science today, Harman explores that central mystery in Metamorphosis: A Natural and Human History (Basic Books, 2025).Metamorphosis, however, isn’t just a biological puzzle: it takes us to the very heart of questions of being and identity, whatever kind of change we humans may undergo. Metamorphosis is a new classic of natural history: a book that, by unveiling a mystery of nature, causes us to relearn ourselves. Learn more about your ad choices. Visit megaphone.fm/adchoices

  • Max Telford, "The Tree of Life: Solving Science's Greatest Puzzle" (W.W. Norton, 2025)
    Jan 30 2026
    Are humans really fish? Why are we the only animals with chins? How much of our DNA do we share with the trillions of bacteria in our bodies? For centuries, scientists have chased the secrets of how life on our planet arose, how it assumed its dazzling diversity of forms, and how we humans are related to everything else on earth. With increasingly sophisticated genetic methods now bringing us ever closer to answers, leading evolutionary biologist Max Telford takes us inside one of science's greatest quests. In the intellectually thrilling The Tree of Life: Solving Science's Greatest Puzzle (W. W. Norton, 2025), Telford shows how reconstructing the web of relationships between all our planet's species, from birds and butterflies to mushrooms and moose, allows us to unravel the epic history of life on our planet. In Telford's hands, the many-branched evolutionary trees that biologists assemble--from Charles Darwin's first sketches to the vast computer-generated diagrams scientists are building today--become time machines that take us on a vivid journey through four billion years of life's history. We meet long-lost ancestors, picturing them in the environment of a much younger earth, and discover where we first acquired our backbones and nipples and, conversely, where we lost our tails. We learn how insects are "actually" crustaceans, and how dogs and wolves are more closely related to whales than to the recently extinct Tasmanian wolves they so resemble. Far from a dry representation of the dead, the tree of life is a living, shifting thing that constantly alters our perspective on the past, present, and future of life on earth. For any reader fascinated by evolution and natural history, The Tree of Life is an essential portal to the distant past and a window onto our collective origins. Learn more about your ad choices.

  • Giuseppe Longo and Adam Nocek, "The Organism Is a Theory: Giuseppe Longo on Biology, Mathematics, and AI" (U Minnesota Press, 2026)
    Jan 20 2026
    A bold reimagining of life that bridges science, philosophy, cybernetics, and the complexities of biological existence The Organism Is a Theory: Giuseppe Longo on Biology, Mathematics, and AI (Giuseppe Longo and Adam Nocek, 2026) is an intriguing synthesis of decades of interdisciplinary research by eminent mathematician and biological scientist Giuseppe Longo. A unique collaboration between Longo and philosopher of technology Adam Nocek, the volume confronts foundational issues in the history of mathematics, computer science, physics, and theoretical biology. Challenging conventional approaches that apply computational and formalist models to the biological world, Longo reveals how the limitations of these models hinder the understanding of organismic complexity, development, and evolution. Through a critique of dominant scientific paradigms, he emphasizes the need for a new biological theory that accounts for the temporal and spatial intricacies of life. Enhanced by Nocek's comprehensive introduction and a fascinating three-part interview with Longo, The Organism Is a Theory offers a bold rethinking of the biosciences, integrating the work of Alan Turing, Bernhard Riemann, Henri Poincaré, Kurt Gödel, and others into Longo's vision of critical biology. Bridging scientific and philosophical discourses, this book creatively applies insights from mathematics, physics, and computing into the study of the organism to present a new theoretical approach to understanding biological complexity that resists reductive mechanistic and informatic explanations.

  • Justin Gregg, "If Nietzsche Were a Narwhal: What Animal Intelligence Reveals About Human Stupidity" (Little, Brown, 2022)
    Jan 18 2026
    What if human intelligence is actually more of a liability than a gift? After all, the animal kingdom, in all its diversity, gets by just fine without it. At first glance, human history is full of remarkable feats of intelligence, yet human exceptionalism can be a double-edged sword. With our unique cognitive prowess comes severe consequences, including existential angst, violence, discrimination, and the creation of a world teetering towards climate catastrophe. What if human exceptionalism is more of a curse than a blessing? As Dr. Justin Gregg puts it in his book If Nietzsche Were a Narwhal: What Animal Intelligence Reveals About Human Stupidity (Little, Brown (US), 2022, Hodder (UK), 2023), there’s an evolutionary reason why human intelligence isn’t more prevalent in the animal kingdom. Simply put, non-human animals don’t need it to be successful. And, miraculously, their success arrives without the added baggage of destroying themselves and the planet in the process. In seven mind-bending and hilarious chapters, Dr. Gregg highlights features seemingly unique to humans – our use of language, our rationality, our moral systems, our so-called sophisticated consciousness – and compares them to our animal brethren. What emerges is both demystifying and remarkable, and will change how you look at animals, humans, and the meaning of life itself. This interview was conducted by Dr. Miranda Melcher whose doctoral work focused on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.
