‘The (evolutionary) origin of birds is largely a matter of deduction. There is no fossil of the stages through which the remarkable change from reptile to bird was achieved.’

W.E. Swinton (British Museum of Natural History, London), ‘Origin of Birds’. In: ‘Biology and Comparative Physiology of Birds’, Marshall (editor), Academic Press, New York, 1960, p.1.
