  • The origins of Darwin's ideas

    The origins of Darwin's ideas
    Jul 3 2026
    No discipline, no sphere of intellectual life, has been untouched by the work of Charles Darwin. He died in 1882 but his ideas are very much alive; they're now central to how we understand the natural world, the human mind, non-human minds, plants, biogeography, morality and emotion, culture, language, and more. But where did his ideas come from? How did they grow out of his travels, his social circle, his hobbies, his particular cast of mind? My guest today is Dr. Janet Browne. Janet is Professor Emerita at Harvard University in the department of the History of Science. She is perhaps best known for her widely acclaimed two-volume biography of Charles Darwin. And she has now published an updated and abridged single-volume version. Here, Janet and I talk about Darwin's life and ideas. We pick up the story during his travels on the Beagle, a five-year voyage that laid the foundation for the rest of his career. We talk about what he was reading, what he was seeing, and how these experiences helped form his most influential work, On the Origin of Species. We discuss Darwin's style as a thinker, as a naturalist, as a writer, and as an experimentalist. We touch on his relationships with contemporaries like Charles Lyell and Alfred Russel Wallace. And we consider his long—and often overlooked—engagements with pigeons, barnacles, plants, and worms. I greatly enjoyed Janet's two-volume biography of Darwin, and I enjoyed this new single-volume edition just as much. So if this episode sparks your interest, I heartily recommend that you check these books out. Alright friends, on to my conversation with Dr. Janet Browne.

  • The sparkling deep

    The sparkling deep
    Jun 20 2026
    It's tempting to see bioluminescence as an oddity, one of those rare eccentricities of life on earth. And, on land, maybe that's true. But our planet is mostly water, and out in the open ocean bioluminescence is utterly commonplace. Creatures of all shapes and sorts sparkle and glow, glitter and pulse. But what are these displays for? Why did they evolve? How did light become the currency of the deep? My guest today is Dr. Sönke Johnsen. Sönke is a Distinguished Professor of Biology at Duke University, where he and his research group study the visual ecology of the ocean. He's the author of a number of books: most recently Into the Great Wide Ocean, about life in the pelagic realm, and The Radiant Sea, a photographic tour of bioluminescence and color, written in collaboration with Dr. Steven Haddock. Here, Sönke and I talk about the open ocean: the most common habitat on our planet, yet one that many people will never experience. We consider the curious distribution of bioluminescence— rare on land, exceptionally prevalent in the ocean, and all but absent in freshwater. We talk about how bioluminescence seems to have evolved—many, many times over in fact. We survey the functions of making light in the deep—from counter-illumination to courtship to revenge. Finally, we consider what Sönke takes to be the biggest remaining puzzle about bioluminescence at sea. Alright friends, if you're enjoying Many Minds, we ask (humbly) if you would think about rating us, reviewing us, leaving us a comment, boosting us on social media, or perhaps haranguing your friends—relentlessly—until they give us a listen. Without further ado, onto my conversation with Dr. Sönke Johnsen. Enjoy! Notes 3:30 – The scientific report by Dr. Johnsen and colleagues describing the bioluminescent octopus, Stauroteuthis syrtensis. 12:00 – A popular article on the bristlemouth. The article reports a scientist's estimate of "as many as a dozen [bristlemouths] per square meter of ocean." 15:00 – A recent discussion of the "burglar alarm hypothesis." 18:00 – The website for the Johnsen Lab at Duke University. 24:00 – A chart and discussion of the depth zones of the ocean. 29:30 – A study by Séverine Martini and Steven Haddock quantifying the prevalence of bioluminescence at different depths. A popular write-up of the same study. 33:00 – A popular article on vertical migration in the ocean, also called "diel vertical migration." A recent scientific study of the phenomenon. 39:00 – A recent article on the evolution of bioluminescence. 45:00 – For detailed scientific discussion of the physical basis of bioluminescence, fluorescence, and other phenomena we discuss, see Dr. Johnson's book, The Optics of Life. 52:00 – For previous episodes on the use of sound in the animal kingdom, see here and here. For our previous episode on electroreception and electric ecology (including in marine organisms), see here. 57:00 – For more on the functions of bioluminescence, see here. For a report of a recently discovered function of bioluminescence, see here. 1:03:00 – An article by Dr. Johnsen about the different colors of bioluminescence present in the deep sea. 1:05:00 – A video of ostracod mating displays. 1:08:00 – For our recent episode on cave art, see here. 1:16:00 – For our earlier episode on firefly synchronization, see here.

  • Is Man the Hunter just a myth?

    Is Man the Hunter just a myth?
    Jun 5 2026
    There's a story about of our past that you know well. It goes like this: At some point earlier in human evolution, we started to hunt. Men in particular—perhaps channeling some deep-seated aggressive impulses—began to seek out big game. This new food source, this bonanza of calories, was what allowed our brains to expand. It changed our bodies and our societies and sent our species off on a whole new track. In short, Man the Hunter made us human. This story—told in different versions, with different points of emphasis—has circulated for decades. It's been debunked and revived, rejected and reimagined. What is the history behind the Man the Hunter idea? How does it square with our current understandings of evolution? Is it, in fact, pure fiction? My guest today is Dr. Vivek Venkataraman. Vivek is an evolutionary anthropologist at the University of Calgary, and an editor-in-chief of the journal Hunter Gatherer Research. He and his collaborators recently published an article on the different layers and meanings of the Man the Hunter idea. Here, Vivek and I lay out those meanings. We talk about how the phrase refers, first, to that popular myth about our evolution, but also to a landmark scientific conference in the 1960s, and to a major finding of research on contemporary hunter-gatherer groups—namely, that men generally do do most of the hunting. We do a little crash-course on the field of hunter-gatherer research, including the kinds of questions it asks and frameworks it uses. We dig into some of the key ingredients of the Man the Hunter myth: the idea that we have aggressive tendencies, the idea that only men hunt, and the idea that hunting played a transformative role in our evolution. We walk through three recent, high-profile studies challenging Man the Hunter ideas in various ways. And we talk about the ever-present danger of projecting our current norms and ideals back in time. Along the way, Vivek and I touch on 2001: A Space Odyssey; reasons why contemporary hunter-gatherers may differ from the hunter-gatherers of long ago; giant sloths; extractive foraging; the case of the Agta, a society in which women do engage in big-game hunting; the forest people and the fierce people; risk and cooperation in sexual divisions of labor; persistence hunting and endurance activities; caregiving and cognition; and honey. Alright friends, I think you'll enjoy this one. On to my conversation with Dr. Vivek Venkataraman. Notes 3:30 – The article by Dr. Venkataraman and colleagues, 'The Meaning and Dividends of Man the Hunter.' Commentaries on the article can be read here. A recent popular essay by Dr. Venkataraman on the same ideas. 5:00 – Raymond Dart's "killer ape" was originally laid out in a 1953 article 'The Predatory Transition from Ape to Man' (unavailable online) and then developed in Robert Ardrey's book, African Genesis. 8:30 – The "dawn of man" scene from 2001: A Space Odyssey. 16:00 – The 1966 conference titled 'Man the Hunter' resulted in a 1968 volume of the same name. 27:00 – A philosophical discussion of the use of the "ethnographic analogy" in reconstructions of the past. The paper describing the "tyranny of the ethnographic record." 33:00 – The classic ethnography, The Forest People; the classic ethnography, Yanomamö: The Fierce People. 36:00 – The article by Chris Boehm on the concept of "reverse dominance hierarchy."
