Page 50 - A few observations on the mode of flight of these birds must not be omitted. The appearance of large detached bodies of them in the air, and the various evolutions they display, are strikingly picturesque and interesting. In descending the Ohio, by myself, in the month of February, I often rested on my oars to contemplate their aerial manoeuvres.
Page 79 - Several writers have misapprehended or objected to the term Natural Selection. Some have even imagined that natural selection induces variability, whereas it implies only the preservation of such variations as arise and are beneficial to the being under its conditions of life.
Page 95 - Every character which must have been formed through the activity of the organism is an acquired character. All characters, therefore, which have been developed by exertion, are acquired, and these characters are inherited from generation to generation. The same holds for all organs atrophied through disuse; the degree of atrophy is acquired and inherited. In the first class we see especially the action of direct adaptation, in the second the results of the cessation of this action. A third class...
Page 79 - ... independently of natural selection. Modifications thus caused, which are neither of advantage nor disadvantage to the modified organism, would be especially favoured, as I can now see chiefly through your observations, by isolation in a small area, where only a few individuals lived under nearly uniform conditions. When I wrote the
Page 79 - In my opinion, the greatest error -which I have committed has been not allowing sufficient weight to the direct action of the environments (ie, food, climate, etc.), independently of natural selection...
Page 50 - At that period, they could be procured as far up the tributary waters of the Ohio as the Great Kenhawa, the Scioto, the heads of the Miami, the mouth of the Manimee at its junction with Lake Erie...
Page 394 - Gass makes a notable entry at this date, p. 224. " The magpie is also plenty here, and woodpeckers of a different kind from any I had before seen. They are about the size of a common red-headed woodpecker ; but are all black except the belly and neck, where the ends of the feathers are tipped with a deep red, but this tipping extends to so short a distance on the feathers, that at a distance the bird looks wholly black." The point is that here is the original appearance in print of Lewis' woodpecker,...
Page 77 - Everything which has been acquired, impressed upon, or changed in the organization of individuals, during the course of their life is preserved by generation and transmitted to the new individuals which have descended from those which have undergone those changes.
Page 382 - ... comparatively few peculiar types simply because a water separation happens to exist in the present geologic period ; nor is it evident why one of the resulting feeble divisions should be granted higher rank than a region of much less geographic extent comprising several times as many peculiar types. Hence the divisions here recognized, and the rank assigned them, are based as far as possible upon the relative numbers of distinctive types of mammals, birds, reptiles, and plants they contain, with...
Page 50 - Kenhawa, the Scioto, the heads of the Miami, the mouth of the Manimee at its junction with Lake Erie, on the Illinois River, and sometimes as far north-east as Lake Ontario, and along the eastern districts as far as the boundary line between Virginia and Maryland. At the present day...
