Science has learned much about the brain. But how well do we understand this organ of the mind? Are we even close to cracking the neural code? Is a groundbreaking theory of consciousness just around the corner?
In this final episode of the brain science -series, Matthew Cobb takes us on a tour of the story of neuroscience. We meet many colourful characters, but this is not just a history for history’s sake. More importantly, this is a reflection on the increasingly clear limits that brain science is coming up against — limits often left invisible behind the thirst for stories about new discoveries.

Dopamine. Serotonin. Endorphins. We have all heard these terms. And these are not just scientific curiosities. Many of us use brain chemistry to describe our feelings and frustrations. Few are those who have never wondered if their brain chemicals are "just off balance".
So how accurate are the popular theories about these mythic molecules?
To guide us through the topic, I'm joined by Judy Grisel—an ex-addict and a world-leading neuroscientist of addiction.
We will discuss all the main elements of brain chemistry by using drugs and addictions as a window into the topic.. Towards the end, we also search for ways to better help those who struggle with addiction.
As always, we finish with my guest's reflection on humanity.

Our brains can feel remote and abstract. Hidden behind Latin names and textbook diagrams, they rarely feel as personal to us as our hearts and stomachs.
In this episode, neurologist and author Pria Anand helps us get a little more intimate with that grey, wrinkly seat of our consciousness.
Together we explore both the structural architecture and the musical synchronies of the brain. We travel across the left and the right brain, "listen" to the meaning of different brain waves, and discuss some of the most perplexing examples from the annals of neuroscience. What emerges is not just an intimate journey through the organ that makes us who we are, but also an exploration on the meaning of pain, identity, and storytelling.

Here is a simple story about the origins of the human brain: All primate brains are good at packing neurons into a small space—they are neural supercomputers. The human brain is just what you’d expect from a monkey of our size: big, packed with neurons, but no more special than that. It's the chimps and gorillas who are special: without cooked food, their brains stay oddly small.
Or so argues Suzana Herculano-Houzel, my guest in last week's episode.
In today's episode, paleo-neurologist Dean Falk argues that the story is stranger still.
I'll let her tell you why.

Why did the great powers of Asia stagnate whilst Europe was rising? This question—often called the Great Divergence—is one of the most defining questions of modern history.
In this talk, I use the case of Britain and India to probe that divide. Did colonialism make Britain rich and India poor? Or was Britain’s rise already underway before conquest? And what does all this tell us about the everyday experiences of the people of on two sides of the divide?
This recording comes from the British Academy, where I was invited to speak at the launch of Bishnupriya Gupta’s An Economic History of India. I was honoured to give this talk on this exceptionally rich topic, speaking after some of the leading experts of India's history.

ORIGINAL SHOW NOTES
Agriculture changed everything. Traditionally, this “Neolithic Revolution” was celebrated for opening the gates of civilisation. Recently, it has been compared to the original sin. But whatever our take on agriculture, we should be puzzled by one thing: Why did our ancestors start to farm in the first place?
It's not like early farmers had improved lives. Quite the opposite, they worked harder and suffered from worse health. So why did so early farmers stick to it? And why did farming spread so far and wide?
Andrea Matranga thinks he has the answer.
An economic historian at the University of Torino, Matranga links agriculture to climate change. This is not a new idea — not as such. After all, agriculture developed in lockstep with the end of Ice Ages. For years, this vague link has formed my own pet-theory on the matter.
But I never paused to reflect on the obvious problem with it. There was never an “Ice Age” in Sudan. Why didn’t humans just farm there?
Matranga has the answer to this and many other puzzles. And surprisingly, his answer is linked to the movements of Jupiter. I will let him tell you why.
We begin this episode covering some previous theories on the origins of agriculture. Next, we dissect Matranga's theory and the evidence for it. Towards the end, we talk about the spread of farming — peaceful and violent — and note a neglected downside to the hunter-gatherer lifestyle. As always, we finish with my guest’s reflection on humanity.

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? Head to last week’s episode on how an ancient climate change paved the way for the very origins of humanity!

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!

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 male and female. Whether you agree with Fuentes or not, it’s an argument worth taking seriously.
We had a great conversation, 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.

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.

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:
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. Stay tuned. And enjoy this episode!

What does war do to the human psyche? It can traumatise. It can cause grief. It can normalise violence and make demons out of the enemy. But difficult times can also elevate our care and compassion. And while much of the new solidarity is focused on those on “our side”, the helping hand does not always stop at the border.
Or so argues anthropologist Greta Uehling, the author of Everyday War (2023). Building on over 150 interviews with Ukrainian civilians and ex-combatants, Uehling’s work brings depth and nuance to the topic - a topic often simplified by naive contrasts between peaceful care and brutal violence. Profoundly optimistic in ways, Uehling is still far from romanticising war. Rather, she paints a humane picture of people finding meaning from the challenges of violent conflict.
Dr Uehling sat down with Ilari to discuss various stories and lessons from Ukraine. As always, the episode finishes with Dr Uehling's own views on humanity.

India’s history isn’t just the story of one nation—it’s the story of one-sixth of humanity. It’s also a lens for understanding how colonialism, democracy, and globalization shaped the modern world.
This mini-series offers a human-centred perspective on that remarkable story, focusing on how politics and trade impacted the lives of ordinary Indians.
In Part 1, we explored the decline of the Mughals and the long stretch of British rule. In Part 2, we turn to India's independent journey as the world’s largest democracy.
To guide us through this complex history, I’m joined again by Bishnupriya Gupta, a professor of economics and the author of the excellent Economic History of India.
In this episode, we discuss:
The legacy of British colonialism in independent India / Why India fell behind the economic miracle of East Asian countries like China / The successes and challenges of India’s democracy in shaping its economic future / What happened to inequality in India during independence?
As always, we finish with my guest’s reflections on humanity.

Following the success of last year’s What About China -trilogy, I’m delighted to introduce a two-part series on the economic history of India. This series examines the origins of modern India by focusing on politics, poverty, and the experience of ordinary Indians from 1600 till today.
The first episode covers the decline of the Mughals and the hugely controversial rule of the British East India Company and, later, the British Crown.
One thing is clear: Most Indians lived in poverty when the British left. So, how much of Indian poverty was due to British policies? How much was shaped by deeper trends? And what should we make of those infamous railways?
To tackle these questions, I’m joined by Bishnupriya Gupta, a professor of economics at the University of Warwick and one of the world’s leading historians of the Indian economy. Her new book, An Economic History of India, provides a uniquely objective and data-driven exploration of India’s history, focusing on the well-being of ordinary people.
In this episode, we discuss:
Indian vs English living standards in 1600 / The impact of British colonialism on India’s economy / The Great Famines of Bengal / What both imperial apologists and Indian nationalists get wrong about the British rule.
In the end, Gupta also explains why Mahatma Gandhi's education might be a clue as to why India lagged behind East Asia in the 20th Century.
Enjoy — and stay tuned for Part II on the era of Independence!
