How can we, humans, look at our relationship to nature differently? In season three of Going Wild, on top of stories about animals, we invite you to journey through the entire ecological web — from the tiniest of life forms to apex predators — alongside the scientists, activists and adventurers who study it. Wildlife biologist and host Dr. Rae Wynn-Grant has been studying wild animals in their natural habitats all over the world for years. Our award-winning podcast takes you inside the hidde ...

In this episode, Patrick is joined by Alex Cagan, a Postdoctoral Fellow in the Cancer, Ageing and Somatic Mutation programme at the Wellcome Sanger Institute, specialising in evolutionary processes in somatic tissue. Tune in as Alex walks us through a fascinating new study, years in the making, looking at somatic mutation rates across 16 mammalian species, spanning 30-fold in lifespan and around 40,000-fold in body mass. This work sheds light on fundamental questions in cancer and ageing across the tree of life. 0:00 Intro 6:00 Collaborating with the London Zoo, and the challenges of sourcing tissue from long-living animals 9:06 Why are naked mole rats so important to the cancer and ageing community? 11:32 The scale and breadth of species sampled in the study 14:53 Is there a ceiling to how many mutations an organism can tolerate? 17:53 Why are intestinal crypts so effective for sequencing somatic mutations? 20:44 Key learnings from driving a 5-year study into somatic evolution 22:46 Are there really any “immortal” species, and what are they? 25:19 Why are cancer rates lower in larger species, and is this related to lower mutation rates, DNA error correction or both? 27:24 Investigating transmissible cancers in Chernobyl 29:40 Is cancer everywhere in the tree of life? 31:23 Alex talks about applying his talent for illustration to science 38:56 The Sanger Tree of Life program, the Darwin Tree of Life project, and the bright future ahead for research on somatic mutations 40:14 Outro Find out more about the study: https://www.nature.com/articles/s41586-022-04618-z
