Inside the Brain: A Journey Through the Halls and the Songs of Consciousness ~ Pria Anand
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.As always, we finish with my guest's reflection on humanity.📖 Dr Anand's new book is The Mind Electric: A Neurologist on the Strangeness and Wonder of Our BrainsWant to support the show?

Not So Simple After All? Apes, Einstein, and the Many Mysteries of the Human Brain ~ Dean Falk
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.Enjoy!DIG DEEPERSee also last spring's episode with Dean Falk on toolmaking and childhoods, as part of the Origins of Humankind -series.

Prologue: The (Very Simple) Story of the Human Brain ~ Suzana Herculano-Houzel
I'm excited to announce that On Humans is launching a new series this fall! This one will explore the wonders of the human brain. The new episodes will drop throughout September and early October. To set the stage, we will revisit a conversation with neuroscientist Suzana Herculano-Houzel, newly re-edited and remastered. It’s the simplest and most elegant story I’ve heard about how our brains came to be — and it sets the stage for the debates to follow. Enjoy! DIG DEEPERHerculano-Houzel's book is called The Human Advantage.You can read a free episode breakdown at OnHumans.Substack.comFor more on human evolution, see the full series on the Origins of Humankind.SUPPORT THE SHOWYou can pledge your support at Patreon.com/OnHumansKEYWORDS Human evolution | Brain evolution | Neuroscience | Biology | Anthropology | Cerebral Cortex | Neuron counting | Comparative neurology | Comparative biology | Comparative anatomy | Harry Jerrison | Paleoanthropology | Human origins |

The Great Question of History: India, Britain, and the Fates of Nations | Live at the British Academy
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.Few case studies illuminate this question as well as the contrast between Britain and India. 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 episode is a live recording 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. How did I do?

Encore | Why Agriculture? Climate Change and the Origins of Farming ~ Andrea Matranga
Climate. Weathers. History.Here's an encore episode to wrap up the mini-series on these themes!This episode on the puzzling origins of farming is one of my all-time favourites on the show. I thought it was a good time to put it out again.You can also read my essay on the topic here.Enjoy!~ORIGINAL SHOW NOTESAgriculture 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.LINKSYou can find my summary of Matranga's theory with links to academic articles at OnHumans.Substack.com.Do you like On Humans?
