The Origin Of Species (1872) Charles Darwin   Introduction WHEN on board H.M.S. Beagle as naturalist, I was much struck with certain facts in the distribution of the organic beings inhabiting South America, and in the geological relations of the present to the past inhabitants of that continent. These facts, as will be seen in […]

The Origin Of Species (1872)   Glossary Glossary of the Principal Scientific Terms Used In the Present Volume I am indebted to the kindness of Mr. W. S. Dallas for this Glossary, which has been given because several readers have complained to me that some of the terms used were unintelligible to them. Mr. Dallas […]

The Origin Of Species (1872) Charles Darwin     Chapter IX: Hybridism THE view commonly entertained by naturalists is that species, when intercrossed, have been specially endowed with sterility, in order to prevent their confusion. This view certainly seems at first highly probable, for species living together could hardly have been kept distinct had they […]

The Origin Of Species (1872) Charles Darwin   Chapter VIII: Instinct MANY instincts are so wonderful that their development will probably appear to the reader a difficulty sufficient to overthrow my whole theory. I may here premise that I have nothing to do with the origin of the mental powers, any more than I have […]

The Origin Of Species (1872) Charles Darwin   Chapter VII: Miscellaneous Objections to the Theory of Natural Selection I WILL devote this chapter to the consideration of various miscellaneous objections which have been advanced against my views, as some of the previous discussions may thus be made clearer; but it would be useless to discuss […]

The Origin Of Species (1872) Charles Darwin   Chapter VI: Difficulties of the Theory LONG before the reader has arrived at this part of my work, a crowd of difficulties will have occurred to him. Some of them are so serious that to this day I can hardly reflect on them without being in some […]

The Origin Of Species (1872) Charles Darwin   Chapter V: Laws of Variation I HAVE hitherto sometimes spoken as if the variations- so common and multiform with organic beings under domestication, and in a lesser degree with those under nature- were due to chance. This, of course, is a wholly incorrect expression, but it serves […]

The Origin Of Species (1872) Charles Darwin   Chapter IV: Natural Selection; Or the Survival of the Fittest How will the struggle for existence, briefly discussed in the last chapter, act in regard to variation? Can the principle of selection, which we have seen is so potent in the hands of man, apply under nature? […]

The Origin Of Species (1872) Charles Darwin   Chapter III: Struggle For Existence BEFORE entering on the subject of this chapter, I must make a few preliminary remarks, to show how the struggle for existence bears on Natural Selection. It has been seen in the last chapter that amongst organic beings in a state of […]

The Origin Of Species (1872) Charles Darwin   Chapter II: Variation Under Nature BEFORE applying the principles arrived at in the last chapter to organic beings in a state of nature, we must briefly discuss whether these latter are subject to any variation. To treat this subject properly, a long catalogue of dry facts ought […]

The Origin Of Species (1872) Charles Darwin   Chapter XV: Recapitulation and Conclusion AS THIS whole volume is one long argument, it may be convenient to the reader to have the leading facts and inferences briefly recapitulated. That many and serious objections may be advanced against the theory of descent with modification through variation and […]
