Last evening, I happened to turn on NPR to hear Terry Gross of the program Fresh Air interviewing a man called Randal Keynes. Mr Keynes is a great-great grandson of Charles Darwin, who has written a book about Charles Darwin, the death of Darwin's first daughter, and the composing of the Darwin's theory of evolution. The book, entitled Darwin, His Daughter, and Human Evolution, is the book upon which the film Creation (recently mentioned on this blog) is based.
