work, for experience in the necessary types of reasoning would seem to have aided his work in other historical sciences. The progressive development of Darwin's thinking—from geology to biogeography, to evolution, and to evolutionary anatomy—becomes readily intelligible when it is seen how similar were his thought processes in all these fields, and how, in several senses, one problem led to another. And his ability to transfer methodologies and theoretical points of view across disciplinary

winning victory over the Platonism of Agassiz and obtaining a fair hearing for Darwin's ideas. But although Gray, a devout Christian, accepted evolution and natural selection, he would not give up design, and he proposed what Dewey called design on the installment plan, the idea that the variations which are selected were specially preordained and foreseen from the beginning by the Creator. *  Dewey, Influence of Darwin on Philosophy. With a fine sense of irony, Darwin entitled his work of 1862 On

Irvine, Apes, Angels, and Victorians (New York: McGraw Hill, 1955), p. 203. That The Expression of the Emotions has not been well understood is clear from the fact that it was a historical dead end. Nobody took up the train of reasoning and developed it, although the work was widely read, and although it did become an element

purpose and function is that they refer to relational properties. *  W. J. Bock and G. von Wahlert, in Adaptation and the Form-function Complex, Evolution, XIX (1965), 269-299, 274, try to get around the difficulties by redefining function to mean an intrinsic property, namely, a physical or chemical property arising from form. One has to supply the right terms for the relation, or else one may make an error. If a thing is to function, it must do so in relation to some action or the like. If it is

fox: I entertain no doubt that the Canis antarcticus is peculiar to the archipelago . The linking of endemism to insularity was to prove of great importance in the development of ideas on evolution. But the biological links between the Falklands and other southern hemisphere land masses also fascinated Darwin for a long period. For many years he carried on a correspondence with J D Hooker, perhaps his closest co-worker and confidant on all manner of biological topics, but particularly on the

And in Darwin's accounts of the Falklands, as well as the catastrophist ideas discussed above, one can detect images of streams gradually wearing away uplands, peat imperceptibly spreading over the land, the sea crumbling away the coast, and deposition, little by little, infilling water

Darwin's discovery of natural selection. His meeting with the ornithologist John Gould in March 1837, in which he was told that the famous Gal pagos finches were not one but several species, has been regarded as a significant spur for the development of his theory of evolution. After this, he soon began to make jottings on species in his notebooks. By July 1837 he was enthusiastic enough to open a separate notebook devoted to Transmutation (the B notebook) that ran concurrently to the geological A
