"Infertile" Quotes from Famous Books
 ... and villages at the foot of the mountain, but the whole of the neighbouring region between Oiwake and Usui-toge, previously fertile, was changed by an ash-rain into an extensive waste. Across this large plain, infertile and little cultivated, situated at a height of 980 metres above the sea, we went without a guide to the village Oiwake, where we lodged for the night at an inn by the side of the road Nakasendo, one of the cleanest and best kept of the many well-kept inns I ...

... said in the seventh essay, the fact of evolution is to my mind sufficiently evidenced by palaeontology; and I remain of the opinion expressed in the second, that until selective breeding is definitely proved to give rise to varieties infertile with one another, the logical foundation of the theory of natural selection is incomplete. We still remain very much in the dark about the causes of variation; the apparent inheritance of acquired characters in some cases; and the struggle for existence within the organism, which probably lies at ...
— Darwiniana • Thomas Henry Huxley
... given by Mr. Darwin in which mongrel animals, descended from the same undoubted species, have been persistently infertile inter se; nor any clear case in which hybrids between animals, generally admitted to be distinct species, have ...

... robbed of their coverings: like the wild hordes of old over beautiful Greece, thus rolls the conquest with fearful rapidity from east to west through America; and the planter now often leaves the already exhausted land, the eastern climate becomes infertile through the demolition of the forests, to introduce a similar revolution into ...
— At Last • Charles Kingsley
... instincts of the working bees have apparently been evolved (at least in all their later social complications and developments) without the aid of use-inheritance—nay, in spite of its utmost opposition. Working bees, being infertile "neuters," cannot as a rule transmit their own modifications and habits. They are descended from countless generations of queen bees and drones, whose habits have been widely different from those of the workers, and whose structures are dissimilar in various respects. ...

... confession was uttered, whatever discoveries may have been made, there has not been the faintest indication of the development of any new species by artificial selection, the individuals of which are fertile among themselves and infertile with the parent stock. It may properly be alleged that there has not been time enough for such a slow process, but it yet remains as true as ever that there is no direct evidence in nature of what ...

... Range is poorly wooded, the dwarf acacia or phulahi (Acacia modesta), the olive, and the sanattha shrub (Dodonea viscosa) are the commonest species. But these jagged and arid hills include some not infertile valleys, every inch of which is put under crop by the crowded population. To geologists the range is of special interest, including as it does at one end of the scale Cambrian beds of enormous antiquity and at the other rocks of Tertiary age. Embedded in the Cambrian strata ...

... greater moment; and, indeed, to show that certain stocks of mankind exhibit, more or less distinctly, the physiological characters of true species. Unions between these stocks, and still more between the half-breeds arising from their mixture, are affirmed to be either infertile, or less fertile than those which take place between males and females of either stock under the same circumstances. Some go so far as to assert that no mixed breeds of mankind can maintain themselves without the assistance of one or other of the ...

... but it indicates very great fertility, while it may be noted also that sterile marriages are comparatively rare among French Canadians, although among English Canadians the proportion of childless families is found to be almost exactly the same (nearly 20 per cent) as among the infertile Americans of Massachusetts. The annual Reports of the Registrar-General of Ontario, a province which is predominantly of Anglo-Saxon origin, show that the average birth-rate during the decade 1899-1908 has been 22.3 per ...
— The Task of Social Hygiene • Havelock Ellis
... producing a new life-form, the female is always the source of the egg, out of which the new creation is to come. This egg, however, is infertile of itself, and must be given life to, by mingling with its germ, an element which only the male can produce and supply. This element is technically known as a sperm, or a spermatozoa. Its function is to fertilize the dormant germ in the egg produced by the female, and ...
— Sane Sex Life and Sane Sex Living • H.W. Long
... remarkable correlation between different sets of individuals which he never recognises. To illustrate what I mean, let me suppose a case. Let there occur in a species three individual physiological varieties—A, B and C—each being infertile with the bulk of the species, but quite fertile with some small part of it. Let A, for example, be fertile with X, Y and Z. Now I maintain it to be in the highest degree improbable that B, a quite distinct individual, with distinct ...
