The castaway in Desert Island Discs this week is geneticist Dr Steve Jones. Eminent in his field, he's made a lifelong study of the evolution of the snail, the reproduction of the fruit fly and the sex life of the slug. He'll be talking to Sue Lawley about the study of genetics, reflecting on its disreputable past, analysing the problems of genetic engineering and discussing the research that inspired his recent Reith Lectures, particularly the evidence that proves that most of the world has descended from 10 Africans.
