On Humans

Why was industrial modernity born in Europe and not, say, China? This is one of the most consequential questions about the origins of the modern world. Yet asking “why Europe” can mislead. The Industrial Revolution was not a European event. It was a British event.
So why was the steam engine invented in Britain, and not France or Italy?
Oxford professor Robert Allen has worked for decades trying to understand this question.
Allen believes that to understand the path to modernity, we must forget grand generalisations about the West. Instead, he asks us to zoom in on two very specific dynamics that shaped the British economy in the 1700s: cheap fuel and expensive workers. Together, they jolted Britain into a path where ever more work was streamlined with the help of machines and fossil fuels — a path that we are still walking on, with AI and robotics simply the latest sightings on this long march of modernity.
In this episode, we discuss the surprising revelations that led Allen to his theory. We discuss the reasons that British wages were high, and we discuss recent scholarship suggesting that this wasn’t the case–or at least, was not the cause for the Industrial Revolution. We also discuss the more humane side of wages, tracing the history of worker wellbeing from the Black Death to today. 
As always in this series, we finish with our guests’ reflections on the future.

GREAT DIVERGENCE: THE MAKING OF THE MODERN WORLD
This episode is part of a series produced by Warwick University’s⁠⁠ ⁠CAGE Research Centre⁠⁠⁠ in collaboration with⁠⁠ ⁠On Humans⁠⁠, searching for explanations to why Western Europe and North America emerged as the most affluent and technologically advanced regions of the modern world. Guided by six expert guests, including a winner of the 2025 Nobel Prize in economics, we approach this topic with balance and breadth, exploring everything from colonialism and fossil fuels to science and technology.

Several inventions mark the progress towards modernity - the Gutenberg printing press, the Galileo telescope, the Watt steam engine. But why was Europe the birthplace of so many of these? 
Joel Mokyr, winner of the 2025 Nobel Prize in economics, thinks the cause was culture. For decades he has asked economists to take intellectual history more seriously. Economies are shaped by new inventions, Mokyr argues, and inventions can only be understood when we understand the culture that gives rise to them. 
But how much did Europe's culture shape its economy? And how to square early modern Europe's progressive culture with it's colonial legacy? Mokyr answers these and other questions in this episodes, finishing with his reflections on the future of technological progress.
Enjoy!

Why did Western Europe become the richest region of the early modern world? Was the rise of the West powered by colonization, inventions, or something else entirely? And what happened to the medieval might of China and India?
The term “great divergence” is increasingly used by historians who want to study this immense question, but who want to do it carefully, without falling into traditional East-West clichés. 
This episode marks the beginning of a five-episode series exploring the state of this research, produced by the University of Warwick’s CAGE Research Centre in collaboration with the On Humans Podcast.
In this opening episode, we meet Kenneth Pomeranz, the historian of China who coined the term "great divergence" in a field-defining book of the same name. We begin by discussing Pomeranz’s groundbreaking approach and the surprising answers that he arrived at. In the second half of the episode, we zoom out and place the rise of the West into the broader story about the history of humanity – a story Pomeranz divides into four parts, with the fifth one beginning right now.
Enjoy!

Something big is coming soon. Stay tuned!
Whilst waiting, you can enjoy one of my all-time favourites from the archives.
A lot of the recent episodes have mentioned the impact of bipedalism in the human story, but the remarks have hardly done justice to the depth of the matter.
Jeremy DeSilva did it justice.
Enjoy! 

ORIGINAL SHOW NOTES
Humans are odd in many ways. But perhaps the oddest of our features is our upright posture. We walk on two legs. And we are the only mammal to do so. 
So why do we walk upright? And why does it matter? 
Jeremy DeSilva is a fossil expert and a professor of paleoanthropology at Dartmouth College. He is also the author of a remarkable book, aptly titled First Steps: How Upright Walking Made Us Human
DeSilva’s treatment of the subject is sweeping: while tracing the journey of human posture, he draws remarkable links between bipedalism and many facets of the human condition, from difficult births to complex language and from lower back pains to the beauty of friendships.
In this episode, we talk about questions such as:
What Darwin got right and wrong about the role of walking in human evolution
When and why did we start walking upright?
Why the common picture of human evolution is wrong - and what would be a better picture
Why walking makes us fragile
How our ancestors survived bone fractures - and why this is a big deal
Why is human birth so difficult
Why walking is so good for us: introducing the “myokines”
What studying the human journey has taught DeSilva about our species

Imagine a group of ancient humans, crafting stone tools at the dawn of humankind. What did these creatures look like? 
To find out, we can stare at the skulls in museums or glance at reconstructions made by paleo-artists. Not a bad start. But what if we move the lens and zoom into their surroundings? What was the scientific “Garden of Eden” like? Was it a lush forest, a dry savanna, or an icy cave? And what can the answer tell us about human nature more broadly?
Denise Su is a world-leading expert on these questions. A paleoecologist at Arizona State University’s Institute of Human Origins, she uses ever-more imaginative ways to get a glimpse into the nature and the weather that set the stage for the human story.
In this episode, we focus on two kinds of “changes” in the ecology of human evolution: both the actual climate change that drummed the beat of human origins, and the theoretical changes in the views of scientists thinking about these topics. Indeed, this episode digs deep into one of the hotly contested questions about the reasons why humans evolved: "the savanna hypothesis".
According to the savanna hypothesis, our naked, upright species evolved because African forests were shrinking and dry savannas emerged instead. Other apes stayed in the shrinking forests, but our brave ancestors took the shot, conquering the vast flatlands. As they did so, they started standing upright to better walk on the savanna and lost their fur, to sweat away the heat of the scorching sun.
I have told versions of this story on the show, and so have many senior guests. Yet even a brief Google search will give you plenty of critics telling that the savanna hypothesis is nothing but a convenient myth.⁠ Articles by Denise Su⁠ are often included in the evidence. So what’s going on? Listen to the episode to find out!
TIMELINE 
Last common ancestor with humans and chimpanzees: 6–7 million years ago 
Ardipithecus ramidus: 4.5–4.2 million years ago 
Australopithecus anamnesis: 4.2–3.8 million years ago 
Austrolopithecus afarensis (e.g. Lucy): 3.9–2.9 million years ago 
Australopithecus deyiremeda: 3.5–3.3 million years ago 
Earliest Homo: about 2.8 million years ago 
Homo erectus: 1.9 million–112,000 years ago 
Homo sapiens: 300,000 years ago till present 

FACT-CHECKING
No factual errors have been detected so far. However, timing estimates and species names are still debated. Furthermore, the “hours” in the metaphorical clock can shift a fair amount based on the “midnight”: our last common ancestor with chimpanzees lived 6 to 7 million years ago, with some estimates pushing the date as far as 8 million. In the episode, our clock is tuned to 6 million years ago.
