CC FINAL EXAM QUOTES Charles Darwin: On the Origin of Species Patrick referred to Darwin’s religious views which are written on pages 430-434, but we did not read specific passages. p.391 “The framework of bones being the same in the hand of man, wing of a bat, fin of the porpoise, and leg of a horse, the same number of vertebrae forming the neck of the giraffe and of the elephant, and innumerable other facts, at once explain themselves on the theory of descent with slow and slight successive modifications. The similarity of pattern in the wing and leg of a bat though used for such different purposes, in the jaws and legs of a crab, in the petals, stamens, and pistils of a flower, is likewise intelligible on the view of the gradual modifications of parts or organs, which were alike in the early progenitor of each class” p.121 “When in any country several domestic breeds have once been established, their occasional intercrossing, with the aid of selection, has, no doubt, largely aided in the formation of new sub-breeds; but the importance of the crossing of varieties has, I believe, been greatly exaggerated, both in regard to animals and to those plants which are propagated by seed. ..Over all these causes of Change, I am convinced that the accumulative action of Selection, whether applied methodically and more quickly, or unconsciously and more slowly, but more efficiently, is by far the predominant Power” p.395 “The other and more general departments of natural history will rise greatly in interest. The terms used by naturalists of affinity, relationship, community of type, paternity, morphology, adaptive characters, rudimentary and aborted organs, &c., will cease to be metaphorical, and will have a plain signification. When we no longer look at an organic being as a savage looks at a ship, as at something wholly beyond his comprehension; when we regard every production of nature as one which has had a history; when we contemplate every complex structure and instinct as the summing up of many contrivances, each useful to the possessor, nearly in the same way as when we look at any great mechanical invention as the summing up of the labor, the experience, the reason, and even the blunders of numerous workmen; when we thus view each organic being, how far more interesting, I speak from experience, will the study of natural history become!” p.163 “Nevertheless, according to my view, varieties are species in the process of formation, or are as I have called them, incipient species. How then does the lesser difference between variates become augmented into the greater difference between species? That this does habitually happen, we must infer from most of the innumerable species throughout nature presenting well marked differences; whereas varieties, the supposed prototypes and parents of future well marked species, present slight and ill defined differences. Mere chance, as we may call it. might cause one variety to differ in some character form its parents, and the offspring of this variety
