For ages, we've pictured our ancestors as living in small, equal societies, sharing everything around campfires without bosses. Think of popular ideas like the "noble savage" or "primitive communism." But what if that picture is wrong? New research in this century challenges these old ideas, suggesting our deep past was far more diverse than we ever imagined. So, what was social life really like for our ancestors? How does this new understanding reshape what we know about human cognition and culture? Are there any true human universals? Today’s guest is the person to answer these questions, or at least some of them..

He is Manvir Singh. Manvir is an assistant professor at the department of anthropology at the University of California, Davis. His research program investigates human behavior, focusing on the origins and nature of widespread sociocultural traditions like shamanism, witchcraft, storytelling, and music. He achieves this by integrating evolutionary, cognitive, and sociocultural methods and theories within his research group. Previously, he pursued a PhD in Human Evolutionary Biology from Harvard University, post-which he was a research fellow at the Institute of Advanced Study in Toulouse. He's also a contributor to The New Yorker and has just had a book come out: Shamanism - The Timeless Religion.

Conversations shape nearly every aspect of our lives. We joke, argue, persuade, gossip, and comfort—all through spoken and unspoken signals we barely even notice. Yet behind every casual chat, awkward silence, or global debate is an invisible force that guides our words and meanings, silently helping us figure out exactly what to say next. How do we instinctively know what matters in a conversation? How do we effortlessly connect, even with strangers? And why do certain symbols or stories captivate us across cultures?

Dan Sperber is a renowned French cognitive anthropologist, social scientist, and philosopher whose groundbreaking work has transformed fields from linguistics and cognitive science to anthropology and philosophy. Alongside linguist Deirdre Wilson, he developed relevance theory, an influential approach to communication and cognition that has impacted linguistics, artificial intelligence, and psychology. His work on cultural evolution, notably the epidemiology of representations, introduced innovative methods for studying how ideas spread and evolve across societies.

We often talk about the modern challenge of work-life balance. However, long before the existence of offices, commutes, and calendars, our ancestors lived as hunter-gatherers. Did they actually enjoy more leisure time than we do? And did the shift to farming mark the beginning of longer workdays and less free time? Today’s guest is the person to answer these questions, or at least some of them…

Mark Dyble is an Assistant Professor in evolutionary anthropology at the University of Cambridge. He has broad interests in understanding variation in behaviour and biology across human populations. Previously, he gained his BA in Archaeology and Anthropology from Cambridge (2008-2011) and an MSc in Cognitive and Evolutionary Anthropology from Oxford (2011-12). Subsequently, he pursued a PhD in Anthropology at University College London (2013-16), supervised by Prof Andrea Migliano and Prof Ruth Mace, conducting empirical fieldwork with Agta foragers in the northern Philippines. After several post-doc stints, he was also a lecturer in Quantitative Anthropology at UCL for four years (2019-2023).
