. Today we refer to such changes as phyletic evolution. Darwin distinguished no qualitative difference between artificial selection and natural selection. In contemporary terms, one can say that he used knowledge of results of artificial selection by man to explain evolution by natural selection. Wallace also emphasized that although species have tremendous potential for increase in numbers, they still maintain constant or near- constant population sizes. He concluded that most natural

of Darwin and Wallace, or the impact of their work on late nineteenth- and twentieth-century science. For the purposes of this introductory book, however, it should be noted that both men considered adaptation to environment to represent evolution by natural selection of the individual. In other words, they considered the individual to be the unit of natural selection. Their theory of natural selection assumed unequivocally that species are mutable; thus they challenged, among other ideas, the

results in a situation wherein individuals or species compete for food, space, special habitats, mates, or other factors in limited supply. We must disregard here the many other contributions to biology and evolution made by these two investigators. Among these are Darwin's theory of sexual selection and Wallace's studies in zoogeography. Darwin in particular was ahead of his time in his far-reaching thought, and many of his scientific predictions were to be realized only in our century. The

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.

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 collecting beetles and pebbles, and some familiarity with the techniques of collecting marine organisms and skinning birds.

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.

. The subject of deviation from a species norm was important to Darwin. When he first began his theoretical work, he treated variations as potential evidence for the occurrence of evolution. But after he developed the theory of evolution through natural selection, variation as a common event in nature was a necessary assumption in a causal system. Just why should Darwin at this point have been struck by the notion that deviations of omission, such as he thought sexual con [page] 380 DARWIN ON MA

its formative period. For Darwin's early thoughts about evolution, his notebooks served as the private place in which he could try out new ideas without fear of premature exposure to the fires of criticism. In July 1838 Darwin had finished the first two transmutation notebooks. They included many notes on man, mind, and materialism. He began the third transmutation notebook at the same time as the notebook, with the intention of separating these two lines of thought more clearly. But the
