Let there be a species which has varied into two forms, each adapted to existing conditions (211/1. "Existing conditions," means of course new conditions which have now come into existence. And the "two" being both better adapted than the parent form, means that they are better adapted each to a special environment in the same area--as one to damp, another to dry places; one to woods, another to open grounds, etc., etc., as Darwin had already explained. A.R.W. (1899).) better than the parent form, which they supplant.英文原著 · 《More Letters of Charles Darwin Volume I》
There must therefore be an intrinsic connection between the conditions and the structural adaptations of the organism, and, SINCE THE CONDITIONS OF LIFE CANNOT BE DETERMINED BY THE ANIMAL ITSELF, THE ADAPTATIONS MUST BE CALLED FORTH BY THE CONDITIONS.英文原著 · 《Darwin and Modern Science》
All parts of the organism are tuned to one another, that is, THEY ARE ADAPTED TO ONE ANOTHER, and in the same way THE ORGANISM AS A WHOLE IS ADAPTED TO THE CONDITIONS OF ITS LIFE, AND IT IS SO AT EVERY STAGE OF ITS EVOLUTION.英文原著 · 《Darwin and Modern Science》
There is another aspect of the Adaptation problem to which I can only allude very briefly. May not our present ideas of the universality and precision of Adaptation be greatly exaggerated? The fit of organism to its environment is not after all so very close--a proposition unwelcome perhaps, but one which could be illustrated by very copious evidence. Natural Selection is stern, but she has her tolerant moods.英文原著 · 《Darwin and Modern Science》
Realising that fitness is the outcome of this fierce struggle, thus turned to account for the first time, we are sometimes led to associate the recognition of adaptation itself too exclusively with Natural Selection. Adaptation had been studied with the warmest enthusiasm nearly forty years before this great theory was given to the scientific world, and it is difficult now to realise the impetus which the works of Paley gave to the study of Natural History. That they did inspire the naturalists of the early part of the last century is clearly shown in the following passages.英文原著 · 《Darwin and Modern Science》
Porportuk was content to plod and accumulate. Klakee-Nah went back to his large house and proceeded to spend. Porportuk was known as the richest Indian in Alaska. Klakee-Nah was known as the whitest. Porportuk was a money-lender and a usurer. Klakee-Nah was an anachronism--a mediaeval ruin, a fighter and a feaster, happy with wine and song. El-Soo adapted herself to the large house and its ways as readily as she had adapted herself to Holy Cross Mission and its ways. She did not try to reform her father and direct his footsteps toward God.英文原著 · 《Lost Face》
