Ella Al-Shamahi grew up as a Muslim creationist, part of a ‘tribe’ that believes that humankind was created whole by a higher power. At university, she enrolled in courses that studied evolution, specifically to prove her professors wrong - but the plan backfired when she became fascinated by evolutionary biology and came to the conclusion that Darwin was, in fact, right all along. Now an accomplished paleoanthropologist, she explores the complex journey of human evolution and the origins of Homo sapiens. In this episode of Ways to Change the World, Ella joins Krishnan Guru-Murthy to discuss her remarkable personal transformation from creationism to science. She also explains why she believes humans haven’t fully evolved to meet the demands of the modern world, and shares her unwavering faith in humanity’s resilience and potential.

Michael Gove, now Lord Gove of Torry in the City of Aberdeen, was a cabinet minister under David Cameron, Theresa May, Boris Johnson and Rishi Sunak. He ran to be leader of the Conservatives twice, famously killed off Boris Johnson's first tilt at the top job but backed him on Brexit, spectacularly falling out with David Cameron in the process in a drama portrayed in sometimes excruciating detail in a book by his ex-wife Sarah Vine. He has now gone back to his first trade of journalism as editor of the Spectator magazine.

Jacinda Ardern is arguably the most globally famous and lauded New Zealand Prime Minister of modern times. 

Her international profile began with her being the world's youngest head of government at thirty seven, who within months had a baby and took it all in her stride. 

But it was her response to the horrific terrorist attack on mosques in Christchurch that gave her hero status amongst progressives around the world - embracing the muslim community in New Zealand and passing strict gun laws in response. 

Her six years as prime minister also meant dealing with the covid pandemic, and the fury and conspiracy theories around lockdowns and vaccines that came with it - many of which targeted her personally. And then in January 2023 - as suddenly as she had arrived on the global stage, she stood down. Her book, A Different Kind of Power, is perhaps the most sensitive and candid account of a leader you could ask for, framed around her desire to be remembered for her kindness.
