Alexandra Tolstoy, Spencer Wells
Tales of the Silk Road
Hay Festival 2003,
Film-maker Revel Guest shares the journey with Tolstoy, author of The Last Secrets of the Silk Road, an account of four friends exploring the way by horse and camel. The same route led Wells, an American geneticist, onto The Journey of Man: A Genetic Odyssey in search of our common African forebear 60,000 years ago.
