Tool use is rare in the animal kingdom—but maybe not as rare as we once thought. Since Jane Goodall famously observed a chimpanzee fishing for termites, many new examples of animals using tools have come to light. Birds using sticks to forage for grubs. Sea otters using rocks to smash open mussels. Digger wasps using stones to close off their burrows. But as these examples mount, so do the scientific questions. What is tool use, really? What different forms does it take? Does it always imply a high degree of intelligence? And perhaps the biggest question of all: Why do some creatures use...

For thousands of years—maybe for as long as we've been human—we've offloaded our thinking. We've counted on our fingers. We've carved tallies into bone. We've invented a long series of tools to help us reason, remember, and manage information—tools like abacuses, calendars, writing systems, calculators, smartphones, and many, many more. So cognitive offloading is hardly new—but the questions around it seem newly urgent. As cognitive technologies accumulate, as opportunities for offloading tempt us at every turn, as headlines warn of "digital dementia" and "cognitive surrender," it...

It's a familiar story in many ways. A child is born, and for years afterward is adored and indulged and anchored to home and family. But then the child grows up and starts crossing that long threshold into adulthood. The transition proves—to say the least—a bit turbulent. Now when I say this story is familiar, I don't just mean familiar to us as human beings. After all, a similar story has long played out among our closest cousins, the chimpanzees. My guest today is .

Thousands of languages are used around the world today, and this linguistic diversity is a precious part of our human heritage. But it's also more than that. Linguistic diversity provides clues—a vast crazy quilt of clues—about how language works, about how history has unfolded, about the dynamics of culture, and about the nature of the human mind. My guest today is . Damián is an based at the at the Pompeu Fabra University in Barcelona. Over the last decade or so, Damián’s emerged as one of the most innovative researchers in the study of language and linguistic diversity. He’s...

Hi friends! We're still taking a bit of a summer pause. We'll be back at the end of August—in the meanwhile, enjoy this listener favorite from our archives! ----- [originally aired September 19, 2024] There's a bit of a buzz out there, right now, but maybe you haven’t noticed. It's in the water, it's in the air. It's electricity—and it's all around us, all the time, including in some places you might not have expected to find it. We humans, after all, are not super tuned in to this layer of reality. But many other creatures are—and scientists are starting to take note. My guest today...

Hi friends! We're taking a bit of a summer pause. We'll be back soon—in the meanwhile, enjoy this listener favorite from our archives! ----- [originally aired July 10, 2025] Childhood is a special time, a strange time. Children are adored and catered to—they're given their own menus and bedrooms. They're considered delicate and precious, and so we cushion them from every imaginable risk. Kids are encouraged to play, of course—but very often it's under the watchful eye of anxious adults. This, anyway, is how childhood looks in much of the United States today. But is this the way childhood...

Hi friends! We're taking a bit of a summer pause. We will be back soon—in the meanwhile, enjoy this listener favorite from our archives! ----- [originally aired May 14, 2025] Some call it the "psychedelic renaissance." In the last decade or so, interest in psychedelic drugs has surged—and not just among Silicon Valley types and psychiatrists and neuroscientists. It's also surged among a stereotypically soberer crowd: academic philosophers. The reasons are clear. With their varied and sometimes transformative effects, psychedelics raise ethical questions, epistemological questions,...

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 . Janet is Professor Emerita at Harvard University in the department of the History of Science. She is perhaps best known for...

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 . 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...

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...
info_outlineThere'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.
