'A marvellous book.' New Scientist. 'A real triumph.' Guardian Marek Kohn's 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. With portraits of Richard Dawkins and Alfred Russel Wallace, amongst others, it moves beyond Charles Darwin to produce a gripping account of the men and scientists behind one of the most important ideas humanity has yet produced. '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
