'A marvellous book.' New Scientist 'A real triumph.' Guardian A Reason for Everything is a brilliant and surprising fusion of science and biography. It is a very human book about the Englishness of evolutionary theory and the lives and personalities - often eccentric and controversial - of those who made it. 'Marek Kohn has written yet another brilliant book about great debates in science.' Neal Ascherson, Observer 'A well-written and carefully researched account of some of the main British players in the world of evolution. Every evolutionist should read it.' Steve Jones, Nature 'An educative and fascinating tale ...Kohn is a wonderful writer.' A. C. Grayling, Literary Review
