  • 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.

  • Babies, dogs, and the riddles of word learning

    Babies, dogs, and the riddles of word learning
    May 22 2026
    It's kind of astonishing, really, that kids ever learn words. Each one poses a little riddle. Does this sound string refer to a person? A category of things? Or maybe some other feature of the blooming, buzzing world? And yet word learning happens. In fact, we now know it begins earlier in infancy than we realized. And we now know, further, that dogs (or at least some dogs) understand words as well. So how does this happen? What do babies and dogs really know about words? And how might we go about figuring this all out? My guests today are Dr. Elika Bergelson and Dr. Claudia Fugazza. Elika is an Associate Professor in the Department of Psychology at Harvard University, where her lab studies how infants learn language. Claudia is a Researcher at Eötvös Loránd University in Hungary, where she and her collaborators study dogs who are especially gifted word learners. In this conversation, Elika, Claudia, and I talk about the thorny question of what it means to understand a word—and whether there are different degrees or kinds of understanding. We consider the challenges posed by different types of words—by nouns, by names, by verbs, by function words, size terms, and more. We discuss why it is that some dogs are so good at learning words, and why infants of a certain age seem to get so much better at it. We talk about learning in different contexts and situations. And we circle the question of how different word learning really is in dogs and babies. Alright friends, before we get to it, one tiny ask: If you've been enjoying Many Minds, you can help us grow by leaving a review or comment or a rating, or by sharing us with a friend or colleague. We would greatly appreciate the support! Without further ado, on to my interview with Claudia Fugazza and Elika Bergelson. Enjoy!

  • The inner life of the hand

    The inner life of the hand
    May 7 2026
    Newton saw in the human hand proof of the divine; Darwin saw a key to our species' success. Many others, too, have described the hand in hyperbolic terms, as a paragon of design, a cornerstone of human uniqueness, an engine of our achievements. But what makes the human hand so powerful? Is it the proportions of the fingers? Is it the opposability of the thumb? Or, could it be none of this? Could it be that the real power of our hands lies—not in the physical design—but elsewhere, out of sight? My guest today is Dr. Matt Longo. Matt is Professor of Cognitive Neuroscience at Birkbeck, University of London. He's the author of the recent book, The Invisible Hand, a wide-ranging tour of the human hand and how it's geared into the brain. Here, Matt and I talk about the difference between the "visible hand"—that is, its physical structure—and the "invisible hand"—its representation in the brain. We consider the evolution of the visible hand and whether there really is anything truly distinctive or impressive about it. We talk about the biology of touch. We tour the invisible hand, discussing how—through cortical magnification—the hand becomes over-represented in the brain's sensory maps. We catalogue a few ways that the hands can go awry. And we talk about whether we should feel any nostalgia for all the hand-based activities and crafts that we're losing. Along the way, we also touch on star-nosed moles and raccoons; tetrapods and the primitive archetype; hand dominance; the parallel between a horse's knee and a human's wrist; tool use, plasticity and abstraction; homunculi; the rubber-hand illusion; supernumerary fingers; the Third Thumb project; and the question of what it might unlock if dolphins had hands. Alright, friends, this is a fun one. On to my interview with Dr. Matt Longo! Notes 3:00 – For discussion of the many traits and behaviors that have been proposed as uniquely human, see our earlier audio essay. 5:00 – For an example of the "if only dolphins had hands" thought experiment, see here. 8:00 – See The Principles of Anatomy as Seen in the Hand by Frederic Wood Jones. 10:30 – Dr. Longo's book, The Invisible Hand, is available open access here. 16:00 – For discussion of how—in horses and other species—the five digits have been reduced or otherwise tweaked over evolution, see here. For an image showing examples of homology between the human forelimb and the forelimbs of other creatures, see here. 19:00 – For a brief discussion of "thumb opposability," see here. For an influential discussion of hand morphology and human hand grips, see work by Mary Marzke here. 30:00 – For our earlier episode on the brain's many maps, see here. 34:00 – For a discussion of Penfield's work and the idea of a "homunculus" in the brain, see here. 42:00 – For an illustration of a "homunculus" with big lips and hands, see here. 44:30 – For more on the star-nosed mole and its distinctive appendage, see here. 49:00 – For the report that first coined the term "numbsense," see here.
