On the Origin of Species: By Means of Natural Selection Or the Preservation of Favored Races in the Struggle for LifeOn the Origin of Species, published in 1859, is widely accepted as the seminal work in modern biology. Through careful observation, Charles Darwin explains how traits can be selected for within a population. This is easily observed in the artificial selection of farm animals, for instance. Darwin's theory caused an uproar that can still be heard today by refuting the Christian doctrine of created breeds, in which all species that exist now have always existed just as they are. It is the very publication of this work that gave Charles Darwin his place of prominence in the history of the theory of evolution, because while he was not the first to suggest such a mechanism, his book and its exhaustive studies made the information widely available. English scientist, naturalist, and geologist CHARLES DARWIN (1809-1882) revolutionized science, especially biology, with his theory of evolution through natural selection. As a passenger aboard the Beagle, Darwin became intrigued by the existence of different species in different geographical locations, which aided in the development of his theory. In addition to The Origin of Species, he is also remembered for The Descent of Man, and Selection in Relation to Sex and The Expression of the Emotions in Man and Animals. |

Стр. 126 - If it could be proved that any part of the structure of any one species had been formed for the exclusive good of another species, it would annihilate my theory, for such could not have been produced through natural selection.
Стр. 119 - If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.
Стр. 1 - When on board HMS 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.
Стр. 82 - The limbs divided into great branches, and these into lesser and lesser branches, were themselves once, when the tree was...
Стр. 47 - Battle within battle must ever be recurring with varying success ; and yet in the longrun the forces are so nicely balanced, that the face of nature remains uniform for long periods of time, though assuredly the merest trine would often give the victory to one organic being over another.
Стр. 44 - The action of climate seems at first sight to be quite independent of the struggle for existence ; but in so far as climate chiefly acts in reducing food, it brings on the most severe struggle between the individuals, whether of the same or of distinct species, which subsist on the same kind of food.
Стр. 49 - ... which it comes into competition for food or residence, or from which it has to escape, or on which it preys. This is obvious in the structure of the teeth and talons of the tiger ; and in that of the legs and claws of the parasite which clings to the hair on the tiger's body. But in the beautifully plumed seed of the dandelion, and in the flattened and fringed legs of the water-beetle, the relation seems at first confined to the elements of air and water.
Стр. 178 - He who can read Sir Charles Lyell's grand work on the Principles of Geology, which the future historian will recognize as having produced a revolution in natural science, and yet does not admit how vast have been the past periods of time, may at once close this volume.
