he was in the possession of the key of natural selection, Darwin worked by a combination of induction and deduction to construct the full theory of evolution by natural selection, as Sir Julian Huxley2 and I3 have shown. But this belongs to a stage in the development of Darwin's thought later than is represented by the first three Notebooks on Transmutation of Species, and is found in the Fourth Notebook, the Sketch of 1842, and the Essay of 1844. The remainder of the Third Notebook is largely

those who solved the problem of evolution and natural selection are by no means complete, but it is already possible to see two curious patterns in the history of thought. The first relates to the manner in which arguments have simply been turned upside down as a result of progress of knowledge. The foremost example of this reversal of direction is the fate of Paley's arguments aimed at proving that the adaptations of plants and animals to their environment show evidence of purposive design.2 First

ingredients which he required, both to establish the fact of evolution and to show that natural selection provided the explanation of how species become modified, was unknown to Lyell who missed the great chance, partly by failing to test the imaginary link between catastrophism and progressionism, and partly because his mind was orientated away from transmutation of species for reasons of theological orthodoxy. How close Lyell came to the facts without recognizing them may be seen in the second

though he had available to him all the basic ingredients out of which Fisher constructed his synthesis, Bateson was blinded by the clean-cut results of such Mendelian crosses as were known to him, appearing to have arisen ready-made without selection, and this prejudiced him against Darwinian selection. He was eventually driven to the untenable view that evolution had been stopped down at the start, and had occurred through the successive removal of inhibitory factors.1 The lesson to be

than a hemisphere, divided into symmetrical areas, which within a limited period of time have undergone certain known movements, we obtain some insight into the system by which the crust of the globe is modified during the endless cycle of changes. 1 This is Darwin's first published reference to his interest in the origin of species. This public statement just three months after becoming an evolutionist, shows he was not afraid to talk about evolution and did not keep this part of his work secret

Weismann August Weismann (1834-1914) was a biologist of Darwin's own stature. His work on the continuity of the germ-plasm, his identification of chromosomes as bearers of hereditary factors, his recognition of regeneration as an adaptive phenomenon, and his search for the origin of evolutionary novelties in germinal variation, together with his acceptance of evolution, natural selection, and sexual selection, made him an ideal correspondent for Darwin.

time, and on what subjects? The only one that can be identified straightaway, and which Darwin himself always regretted, was mathematics. It would be interesting to know how Darwin would have explained to himself the most curious fact in his intellectual evolution; how he became a scientist. When he sailed in the Beagle he was a rather ordinary well-to-do young man, with great courage and much horse-sense, no academic qualifications whatever, a love of riding and shooting, a great interest in

need not be taught at all; it will fall into place, later, when and if required. Before Darwin, there was no biology, only a string of facts, and he brought the first unifying general principle into the chaos: evolution. At the present time, although the amount to be discovered is even greater, there are numbers of principles and laws of wide validity, with the help of which programmes of research and of study can be drawn up, with great tidiness and economy of time. Another lamentable error is

This applied not only to evolution and natural selection in wild and domestic plants and animals, man, and emotions, but to the elucidation of coral reefs, volcanic action, elevation and subsidence, foliation in geological formations, metamorphism of igneous and sedimentary rocks, pollination in orchids, primroses
