Michael Rosen talks to anthropologist Jamie Tehrani about how fairy tales travel the world, ever changing and evolving. He’s traced their transmission across oral traditions: the kinds of plots, characters and motifs that endure. From the Iranian Prince Zāl to Little Red Riding Hood's compelling Chinese cousin: The Tiger Grandmother.
