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 […]

The Origin Of Species (1872) Charles Darwin   Chapter XIV: Mutual Affinities of Organic Beings: Morphology: Embryology: Rudimentary Organs Classification FROM the most remote period in the history of the world organic beings have been found to resemble each other in descending degrees, so that they can be classed in groups under groups. This classification […]

The Origin Of Species (1872) Charles Darwin   Chapter XIII: Geographical Distribution Continued Fresh-water Productions AS LAKES and river-systems are separated from each other by barriers of land, it might have been thought that fresh-water productions would not have ranged widely within the same country, and as the sea is apparently a still more formidable […]

The Origin Of Species (1872) Charles Darwin   Chapter XII: Geographical Distribution IN considering the distribution of organic beings over the face of the globe, the first great fact which strikes us is, that neither the similarity nor the dissimilarity of the inhabitants of various regions can be wholly accounted for by climatal and other […]

The Origin Of Species (1872) Charles Darwin   Chapter XI: On the Geological Succession of Organic Beings LET us now see whether the several facts and laws relating to the geological succession of organic beings accord best with the common view of the immutability of species, or with that of their slow and gradual modification, […]

The Origin Of Species (1872) Charles Darwin   Chapter X: On the Imperfection of the Geological Record IN THE sixth chapter I enumerated the chief objections which might be justly urged against the views maintained in this volume. Most of them have now been discussed. One, namely the distinctness of specific forms, and their not […]

The Origin Of Species (1872) Charles Darwin   Chapter I: Variation Under Domestication Causes of Variability WHEN we compare the individuals of the same variety or sub-variety of our older cultivated plants and animals, one of the first points which strikes us is, that they generally differ more from each other than do the individuals […]

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 […]

IN the discussion on Sexual Selection in my Descent of Man, no case interested and perplexed me so much as the brightly-coloured […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Introduction THE NATURE of the following work will be best understood by a brief account of how it came to be written. During many years I collected notes on the origin or descent of man, without any intention of publishing […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Chapter XXI – General Summary and Conclusion A BRIEF summary will be sufficient to recall to the reader's mind the more salient points in this work. Many of the views which have been advanced are highly speculative, and some no […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Chapter XX – Secondary Sexual Characters of Man- Continued WE have seen in the last chapter that with all barbarous races ornaments, dress, and external appearance are highly valued; and that the men judge of the beauty of their women […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Part Three – Sexual Selection in Relation to Man and Conclusion Chapter XIX – Secondary Sexual Characters of Man WITH mankind the differences between the sexes are greater than in most of the Quadrumana, but not so great as in […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Chapter XVIII – Secondary Sexual Characters of Mammals- Continued QUADRUPEDS use their voices for various purposes, as a signal of danger, as a call from one member of a troop to another, or from the mother to her lost offspring, […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Chapter XVII – Secondary Sexual Characters of Mammals WITH mammals the male appears to win the female much more through the law of battle than through the display of his charms. The most timid animals, not provided with any special […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Chapter XVI – Birds-Concluded WE must now consider the transmission of characters, as limited by age, in reference to sexual selection. The truth and importance of the principle of inheritance at corresponding ages need not here be discussed, as enough […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Chapter XV – Birds- Continued WE have in this chapter to consider why the females of many birds have not acquired the same ornaments as the male; and why, on the other hand, both sexes of many other birds are […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Chapter XIV – Birds- Continued WHEN the sexes differ in beauty or in the power of singing, or in producing what I have called instrumental music, it is almost invariably the male who surpasses the female. These qualities, as we […]

  Descent of Man [ 1871 ] Charles Darwin [ 1809 – 1882 ]   Chapter XIII – Secondary Sexual Characters of Birds SECONDARY sexual characters are more diversified and conspicuous in birds, though not perhaps entailing more important changes of structure, than in any other class of animals. I shall, therefore, treat the subject […]
