'The fact of evolution is the backbone of biology, and biology is thus in the peculiar position of being a science founded on an unproved theory - is it then a science or a faith? Belief in the theory of evolution is thus exactly parallel to belief in special creation - both are concepts which believers know to be true but neither, up to the present, has been capable of proof.'
~ L. Harrison Matthews - FRS, Introduction to Darwin's The Origin of Species, J.M. Dent & Sons Ltd, London, 1971, p. xi.
