The celebrated primatologist Jane Goodall died last week at the age of 91. In tribute, we’re re-sharing this interview from 2020, where she reflects on the years she spent living with the wild chimpanzees in Gombe in eastern Tanzania and why she believes the best way to bring about change is to ‘creep into people’s hearts’.

Jane shot to fame when she appeared on the cover of National Geographic magazine in 1963 and appeared in a documentary film directed by Orson Welles. Her ground breaking observations introduced us to the social and emotional lives of wild chimpanzees and changed our view of what it is to be human. Images of her younger self play-wrestling with baby chimps make Jane feel slightly apprehensive now but at the time she didn’t give it a second thought. However, she did take care to protect her young son. Seeing distressing footage of chimps who were living in captivity, she gave up fieldwork to become an activist, working to liberate chimpanzees that were being used for medical research or sold for meat or as pets, and setting up chimp sanctuaries for animals that were no longer able to live in the wild. For the last thirty years, she has campaigned gently but relentlessly to protect wild animals and wild places, touring the world and performing on stage in front of huge audiences. Her global youth programme, Roots and Shoots has inspired and empowered millions of people to understand and respect nature, leading some to call her ‘the mother Theresa of the environment’. A label she dislikes.

How much information can you extract from a burnt fragment of human bone?

Quite a lot, it turns out - not only about the individual, but also their broader lives and communities; and these are the stories unearthed by Jacqueline McKinley, a Principal Osteoarchaeologist with Wessex Archaeology.

During her career, Jackie has analysed thousands of ancient burial sites across the British Isles, bringing to life the old traditions around death via often cremated human remains. She's also assisted criminal investigators with forensic analysis, and contributed to some of the UK's best-loved archaeological TV shows. And one thing she’s absolutely clear about: far from being macabre, osteoarchaeology is more about the living, than the dead...

In conversation with Professor Jim Al-Khalili, Jackie talks about the stories we can derive from skeletal remains, how western attitudes to death have gone through a major recent shift, and why she's kept some of her late father's bones.

Doyne Farmer is something of a rebel. Back in the seventies, when he was a student, he walked into a casino in Las Vegas, sat down at a roulette table and beat the house. To anyone watching the wheel spin and the ball clatter to its final resting place, his choice of number would’ve looked like a lucky guess. But knowing the physics of the game and armed with the world’s first wearable computer, which he’d designed, a seemingly random win was actually somewhat predictable.

Doyne is an American scientist and entrepreneur who pioneered many of the fields that define the scientific agenda of our time, from chaos theory and complex systems to wearable computing. He uses big data and evermore powerful computers to apply complex systems science to the economy, to better predict our future. Much like roulette, economics can appear random but, with the right tools and understanding, it is anything but.

Now Director of the Complexity Economics Programme at the Institute for New Economic Thinking at Oxford, Doyne says there’s a real need to act, to use these powers of prediction to help resolve one of the most pressing questions of our time - how best to prevent climate change.
