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 chimpanzees
• Against “Man the Toolmaker”: Tool use in other apes
• The walking ape: how bipedalism shaped our ancestors
• Origins of language
• Origins of music
• Size matters, but… The early evolution of the human brain

As always, we finish with the guest’s reflections on humanity.

#2 An Unusual Ape (Tuesday 2nd of April)

In episode two, we follow the first steps on the human line, exploring how abandoning life in the trees paved the way for many of our human oddities.

Key questions: Why was upright posture so important? What did it do to parents and children? When did the brains of our ancestors start to show human oddities?

Your guide: Dean Falk, a leading expert on brain evolution at the University of Florida. She recently published a book titled A Botanic Age, looking at human evolution before the Stone Age.

The science of human origins has made great progress in answering these timeless questions. From carbon isotopes to ancient DNA extraction, we now have unprecedented tools to explore our past. But with all this detail, it’s easy to miss the forest from the trees.

To fill this gap, On Humans has partnered with CARTA — a UC San Diego-based research unit on human origins. Together, we have designed a five-episode journey to dig deep into the new science of the origins of humankind.

Together, these episodes explore the emerging science of how we became the puzzling and wonderful creatures we are today.

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!

Why are history books so full of men? Why have so many societies treated women as property?

In short, why is patriarchy so pervasive?

A casual thinker might find an easy answer from biology. Men tend to be bigger and stronger. Hence, they get to run the show. “Just look at chimpanzees!”

But this explanation has obvious problems. Indeed, female chimpanzees don’t have much power in their groups. But female bonobos do. And looking at humans, not all human societies are patriarchal — not nearly to the same extent.

We don’t need to look at modern Scandinavia to get inspiration for women’s empowerment. Quite the contrary, equality between the sexes might have been the norm throughout most of the human story. This might sound surprising given the rates of patriarchy across time and space. However, it is supported by a simple finding: gender equality is relatively common in existing hunter-gatherers. This stands in stark contrast to their agricultural neighbours.

This old finding became part of the scholarly conversation again in late 2024 when a new paper reported high levels of equality between husbands and wives amongst married hunter-gatherers. The levels of equality surprised the scholars themselves. But all this raises an interesting question: why is this? Why would hunting and gathering incline societies towards equality? Or vice versa, why would agriculture nudge societies towards male power? And what should we make of the many outliers from this pattern, like the matriarchal farmers of northeastern India?

To discuss these topics, I invited the lead author of the recent paper to the show.

Angarika Deb is a cognitive anthropologist, soon to earn her PhD from the Central European University. Despite her young career, she has produced tons of interesting articles on gender inequality around the world. A wide-ranging conversation was guaranteed.

“We are survival machines – robot vehicles blindly programmed to preserve the selfish molecules known as genes.” - Richard Dawkins in The Selfish Gene

In 1976, Richard Dawkins published one of the most iconic science books of all time. It has inspired a generation of science enthusiasts. But unsurprisingly, many readers disliked the idea of being but a “robot vehicle” or a “survival machine” for some tiny molecules — especially if these molecules are best served by repeated pregnancies or donations to a sperm bank.

Yet Dawkins was right on one thing: “however much we may deplore something, it does not stop being true.”

So what is true?

I have previously written about one claim in the Selfish Gene which is certainly not true. This is the claim that, if we accept the book's biological theories, then we humans must be “born selfish”. Even Dawkins has accepted that this was a "rogue" claim that readers should "mentally delete". You can hear more by heading to episode 20 of On Humans.

But what about the underlying science? Are selfish genes still the right way to think about the facts of evolution?

Not so, according to Eva Jablonka.

You might remember Jablonka from episode 36 on the evolution of consciousness. But before her work on consciousness, Jablonka was famous for her research on epigenetic inheritance -- literally, "inheritance beyond the gene". So what is epigenetic inheritance? What do we know about it scientifically? And does it matter philosophically?

I hope you enjoy this conversation.

Each year, the World Happiness Report ranks countries based on their citizen's life satisfaction. My home country, Finland, tends to come at the top. Sure. But lessons can we draw from all this? Beyond patting Finns on the back, can we distil some more insights from the report?

I got to discuss this with Lara Aknin, co-editor of the World Happiness Report. In this previously unpublished clip, Aknin explains the major findings from the World Happiness Report and reveals the “single best predictor of happiness” across countries.

Many traditional societies accept polygyny (one man, many wives). Monogamy, too, is practised across the globe. But what about polyandry — one woman, many husbands? Is this a "dubious idea" as sometimes suggested by evolutionary theorists?

In this bonus clip, anthropologist Katie Starkweather offers interesting examples of formal and informal polyandry from around the world. She also brings nuance to theories about jealousy in men and women.

(This is a previously unpublished clip from my conversation with anthropologist Katie Starkweather, as published in episode 43.)

Happy New Year 2025! To celebrate, here is an encore of what proved to be the most popular episode of 2024.

This rerun combines episodes 30 and 31 into one epic journey towards the frontiers of human understanding. My guest is Donald Hoffman. Our topics are consciousness, cosmos, and the meaning of life.

Enjoy!

Original show notes

Laws of physics govern the world. They explain the movements of planets, oceans, and cells in our bodies. But can they ever explain the feelings and meanings of our mental lives?

This problem, called the hard problem of consciousness, runs very deep. No satisfactory explanation exists. But many think that there must, in principle, be an explanation.

A minority of thinkers disagree. According to these thinkers, we will never be able to explain mind in terms of matter. We will, instead, explain matter in terms of mind. I explored this position in some detail in episode 17.

But hold on, you might say. Is this not contradicted by the success of natural sciences? How could a mind-first philosophy ever explain the success of particle physics? Or more generally, wouldn't any scientist laugh at the idea that mind is more fundamental than matter?

No — not all of them laugh. Some take it very seriously.

Donald Hoffman is one such scientist. Originally working with computer vision at MIT's famous Artificial Intelligence Lab, Hoffman started asking a simple question: What does it mean to "see" the world? His answer begins from a simple idea: perception simplifies the world – a lot. But what is the real world like? What is “there” before our perception simplifies the world? Nothing familiar, Hoffman claims. No matter. No objects. Not even a three-dimensional space. And no time. There is just consciousness.

This is a wild idea. But it is a surprisingly precise idea. It is so precise, in fact, that Hoffman’s team can derive basic findings in particle physics from their theory.

This was fun!

Last Wednesday saw the first-ever live recording of On Humans. The event was held at the London Business School, courtesy of the LBS's China Club. My guest was MIT Professor Yasheng Huang, familiar to regular listeners from the China trilogy published earlier this fall.

In this new episode, we keep tackling the origins of modern China. This time, we draw insights from Huang's two upcoming books: Revisiting the Needham Question and Statism With Chinese Characteristics. The conversation is structured around five themes: 1) the "Needham Question"; 2) Keju exams; 3) Scale; 4) Scope; and 5) The Eighties. Expect juicy insights to questions such as:

• Why was more Buddhism linked to more inventions in ancient China?
• How does footbinding relate to China's technological decline?
• Has China's GDP growth stopped serving Chinese workers?

Towards the end of the conversation, Huang also shared his memories of working in China through the 1989 crackdown at Tiananmen Square.

Enjoy!
