The world is full of religions, but none as timeless as shamanism. And whilst many modern religions have shed their shamanic skins, the shaman is rarely as far away as we have been told.

Or so argues anthropologist Manvir Singh in his book, Shamanism: The Timeless Religion.  

Singh’s work is fascinating in its capacity to link the exocit with the familiar, showing how rainforest rituals are not so far removed from urban modernity as we might think.

Today, I will have the rare chance to enjoy Singh's insights together with you, as a listener. The hard work will be done by Kensy Cooperider, the host of the Many Minds Podcast.

Many Minds is one of my own go-to shows and has a lot to recommend for it. Just like On Humans, it breaks down complex scientific concepts about humanity into easy-to-follow yet in-depth conversations. Yet unlike On Humans, it has insanely well-referenced show notes! Just check this one out.

Kensy and I had a beachside chat this November and decided it would be good to introduce ourselves to each other's audiences. So here we go!

Happy 2026! On Humans has typically marked the coming of January by revisiting the previous year’s most popular episode. This time, the New Year special packs the five-hour-long "Origins of Humankind" series into one fast-paced dive through deep time.

By mixing highlights from the original interviews with fresh narration, this episode offers a captivating journey through many of the great topics around human origins, such as:

• Who were the first primates
• The role of fruits, snakes, and predators
• The human solution to danger
• How to grow a human brain?
• What did our ancestors eat?
• Effects of our upright posture
• Origins of music & language
• How Homo sapiens took over the world

Enjoy!

“The podcast is great, but one thing hasn’t been covered yet: humour. It’s an essential part of our human condition, and would certainly be worth an episode.”

This listener feedback was easy to agree with.

From standup comedy to nervous laughter, our lives are filled with chuckles and giggles.

Why?

Why do adults laugh at witty jokes whilst children laugh at the simple pleasures of peek-a-boo? And why should any of us laugh in the first place?

My guest is Mira Magdalena Sickinger. a poet and a philosopher of humour from the University of Vienna.

We cover a lot in the discussion: from the social roles of humour, to the politics of joking, and the therapeutic effects of a humorous attitude. In the course of the conversation, we cover the views of many intellectual giants, from Sigmund Freud to Immanuel Kant — and while the conversation includes a handful of silly jokes (be warned), it ends with a deeper reflection on how humour can serve as a window into the human condition itself.

We are a movable species. In less than 50 thousand years, Homo sapiens has penetrated practically all corners of the earth.

This is an episode about those epic migrations, with a focus on the two furthest edges of the human migratory map: the Americas in the West and the Polynesian islands in the East. In the end, we discuss emerging evidence that those branches met each other -- work coming directly out of the work of my guest, Andrés Moreno-Estrada.

European thinkers once divided humanity into distinct "races". The idea stuck, even if the science moved on. The shape of humanity, it turned out, is far messier than the old race theorists ever imagined.

This much is well known.

Still , genetics does study different human "populations". Biological differences between these populations are reported every day. So have we simply changed words? Has anything really changed?

Yes, everything has changed.

To explain why, I'm glad to have Diyendo Massilani on the show.

Trained in France and Gabon, Massilani runs a lab at the Yale School of Medicine, where he studies ancient DNA and human adaptations. This fall, his lab has produced one of the most interesting analysis of human biodiversity that I have ever seen. I'm proud to feature it on the podcast before publication.

Our conversation begins from the counter-intuitive implications of the Out of Africa theory, and its significance for ideas about race. We then discuss Massilani's own analysis about how the level of genetic differences between modern-day humans.

As always, we finish with my guest's reflections on humanity.

Genetics is rewriting the human story. This week, On Humans takes you behind the scenes of this rapidly evolving frontier via three live-recordings, captured at the Salk Institute's CARTA symposium on ancient DNA.

The first episode explores the differences between us and the Neanderthals.

For centuries, we tried to understand Neanderthals through stones and bones alone. Now genetics is offering a new tool, allowing researchers to see how ancient bodies and brains developed. In this opening episode, David Gokhman explains what these new tools are revealing about us, Neanderthals, and the lines between us.

The science of human origins keeps producing new theories. But are we any closer to telling a true story of human origins? Or are we simply drowning in data? 

Earlier this November, the chair of UCSD’s Department of Anthropology invited me to explore this question in a campus talk. My optimistic claim was that underneath many of the field’s important debates, a powerful story has been emerging. At its core, this is a story about calories, cooperation, and climate change. And at the centre of it are not men hunting or women gathering.

At the centre of it are children playing and learning.

Here is the recording from the talk .

Check out also my Substack essay inspired by this talk, with many of the pictures and graphs from the slides!

PS. I was in San Diego to attend a CARTA symposium on the role of genetics in the study of human origins. I managed to record three episodes behind the scenes.

Live recordings coming soon!

No major errors have been found yet. As a small correction, the mention about macaques vs giraffe's should have been about neurons in the cortex, not total neurons in the brain. The main idea doesn't change.

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. 

Enjoy!

Dopamine. Serotonin. Endorphins. We have all heard these terms. And these are not just scientific curiosities. 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.

No major mistakes have been found so far.
As a minor note, the SSRI study we mention in healthy volunteers primarily assessed cognitive processing (reinforcement learning/sensitivity) rather than self-reported “emotional flattening”; however, general blunting of emotional responses in healthy participants has been reported by earlier researchers.
