    Climate, Water, and the Origins of Colonialism ~ Tirthankar Roy

    Before they built empires, the Europeans built ports. Across Africa and Asia, European sailors arrived as merchants. They traded and negotiated. They defended their interests—sometimes with cannon fire. But they were not trying to govern a foreign land. Yet things changed. Why? Historian Tirthankar Roy has a bold new answer. Roy is a professor at the London School of Economics, where he teaches a renowned course on the economic history of colonialism. His most recent book isThe Origins of Colonialism. And in it, Roy explains that we cannot understand the origins of European Empires in Asia and Africa by simply zooming into the actions of Europeans. We must understand what happened to the elites of the lands being conquered. And more often than not, that had to do with the rains, rivers, and access to water. In this episode, Roy explains how his theory sheds light on the rise of the British Empire in India. Along the way, we also sketch many broader ideas about the story of global colonialism, from Chinese ports to the conquest of Burma and from the water problems of Mumbai to the rubber plantations of Congo. Enjoy! This is part two of this summer’s mini-series on the way climate has shaped the human story. Curious to hear more?

    How Climate Crafted Humanity (Or Did It?) ~ Jessica Thompson

    On Humans is back from the break! To mark the summer heat, here is a two-part series on how climate has shaped the human story. In next week's episodes, we will explore the role of water and weather in the origins of European colonialism. But today, we start by crawling deeper into the past: to the origins of humanity itself. In this episode, Yale professor Jessica Thompson helps us navigate one of the most influential ideas in human evolution: that an ancient climate change pushed our ancestors out of the jungle, onto the savanna, and eventually toward big brains, meat-eating, and tool use. This is a captivating story. It has been mentioned many times on the show. But do the details hold up? What follows is a sweeping account of human origins, which nuances — but does not reject — the grand arc explored in The Origins of Humankind series. This is a story about a climate that has never remained steady. It serves as a poignant reminder of the weather's power to shape human destiny. But it’s also a story about human resilience and our capacity, from the very beginning, to defy the iron laws of ecology. Enjoy! Thoughts about the episode? Share them at OnHumans.Substack.com⁠.

    An Essential Difference? Males, Females, and the Spaces In Between ~ Augustín Fuentes

    Binary thinking is out of fashion. But what about biological sex? Whatever we might say about diversity and fluidity, the ideas of “male” and “female” seem essential in biology. I’ve taught the subject. I’ve drawn bees and flowers, with arrows from anthers to ovaries. I’ve used the terms “dad cell” and “mother cell” while doing so. I don’t know how I could have done it any differently. And maybe that’s just fine. Human sex cells are binary: sperm and egg. But here’s the twist: humans aren’t sex cells. Humans are animals. And animals aren’t so easily grouped. XY chromosomes don’t always produce a penis. And when we turn to hormones, brains, and behaviours, the picture gets even messier. Or so argues Princeton Professor Agustín Fuentes, a leading expert on human biology. His new book, Sex Is a Spectrum, came out this week. It makes the case that biology no longer supports a sharp separation between the male and the female. I approached this topic with a mix of curiosity and scepticism. And while I'm still unsure of what to make of the conclusion, I do not regret the conversation one bit. We had a great chat, ranging from hermaphroditic worms to sex-changing fish, and from gender stereotypes to intersex humans. At times, I pushed back. But I learned a lot throughout the conversation. I hope you do, too. Thoughts about Fuentes’s argument? Or my takes? Share them at onhumans.substack.com. You'll also find more links to dig deeper.

    The Rest is History: From the Origins of Farming to the Dawn of Modernity ~ Johannes Krause

    And so it ends! In the final episode of The Origins of Humankind, we explore the aftermath of the story so far—the story of how one peculiar species, Homo sapiens, evolved, spread, and outlived its relatives. Guiding us through this final chapter is Johannes Krause once again. Together, we uncover the emerging picture of the global spread of farming, pastoralism, and other key ingredients of modernity. Along the way, we explore some of the central questions of history—from the origins of inequality to the surprisingly pivotal role played by the peoples of the Eurasian steppe. (Yes, Mongols will make an appearance! But the story of the steppe goes much deeper...) As always, we end with my guest’s reflections on humanity. Enjoy!

    A Human Like No Other: The Rise of Homo Sapiens ~ Johannes Krause

    The time has come: This is where our story truly begins. In Episode 4 of The Origins of Humankind, we finally turn the spotlight on Homo sapiens. Guiding us through this journey is Johannes Krause, director of the Max Planck Institute for Evolutionary Anthropology and a pioneer of one of the greatest scientific revolutions of our time: the science of ancient DNA.This ability to extract DNA from fossils has transformed our understanding of the human past—giving us tools to tell a genuinely global history of our species. In this episode, we use the magic of ancient DNA to explore the world our species was born into: a weird, wild Ice Age planet teeming with other human species, from Flores Hobbits to Neanderthal Giants. We touch on big questions, such as: How did Homo sapiens spread around the world?Why were our ancestors so successful? How did climate changes shape their story?What was palaeolithic life like?What happened to the Neanderthals? (Be prepared for a plot twist!) We end at the dawn of the Holocene—the warm, wet period that would give rise to farming, cities, and everything we call “history.” That’s the story we’ll tackle in the final episode of The Origins of Humankind.

    What Is a Human? The New Science of the Genus Homo ~ Chris Stringer

    Things are about to get personal... In episode 3 of The Origins of Humankind, we zoom into the birth and spread of humanity itself. Our guide is the iconic Chris Stringer, one of the most influential paleoanthropologists alive. Together, we trace the origins of our genus and the emergence of Homo sapiens as the last surviving human species. While doing this, we meet many oddities, such as rhino hunting along the River Thames, but we also explore some of the biggest questions in human evolution: What is a human?Why did we evolve big brains?Why do we have such long childhoods?Is Homo sapiens truly unique — or just one human among many?As always, we finish with my guest's reflections on humanity.

    An Unusual Ape: The Deep Origins of Our Human Oddities ~ Dean Falk

    The story continues! In part 2 of the Origins of Humankind, we trace the first steps of our ancestors after they left the chimpanzee lineage. To get humanity going, our ancestors had to wander through millions of years of what anthropologist Dean Falk has called the Botanic Age. It's a time shrouded in mist, yet it may hold the key to some of humanity’s most defining traits — from language and music to our clumsy toes and our large brains. On this walk through the mysteries of the Botanic Age, our guide is Dean Falk herself. She is a Distinguished Professor of Anthropology and the world's leading expert on human brain evolution. Together, we try to make sense of topics such as: The common ancestor between humans and chimpanzeesAgainst “Man the Toolmaker”: Tool use in other apesThe walking ape: how bipedalism shaped our ancestorsOrigins of languageOrigins of musicSize matters, but… The early evolution of the human brain As always, we finish with the guest’s reflections on humanity.
