Randal Keynes

Have you ever wondered about the personal life of the man who developed the theory of evolution? On today's Fresh Air, the conservationist Randal Keynes — Charles Darwin's great-great grandson — talks about the man behind the science: his relationship with his wife, Emma, and how they handled the death of their daughter. In 2002, Keynes wrote a book on the subject called Annie's Box, which shares personal letters and diaries documenting how Darwin cared for his daughter in the last months of her life. The book is the basis for the new film Creation.
