I tried once or twice to explain to able men what I meant by "natural selection," but signally failed.

From the indifference evinced to the papers which first propounded the theory of natural selection, Darwin drew the inference that it is necessary for any new view to be explained at considerable length in order to obtain the public ear.

He submits that a false theory would hardly explain in so satisfactory a manner as does the theory of natural selection the several large classes of facts marshalled in the two volumes now under review.

In order to get practice in this, undertake the manufacture of a few definitions, using terms such as charity, benevolence, natural selection.

Finally, it is worth noticing, that, though natural selection is scientifically explicable, variation is not.

Mr. Darwin finds then the disseminating and improving power, which he needs to account for the development of new forms in nature, in the principle of "Natural Selection," which is evolved in the strife for room to live and flourish which is evermore maintained between themselves by all living things.

The contemporary and independent discovery by Wallace and Darwin of the principle of natural selection furnishes, perhaps, a rough parallel, but the fact serves to show how impalpable and universal is the spread of ideas, how impossible it is to settle literary indebtedness or construct literary genealogy with any hope of accuracy.

He regarded the widespread acceptance of the theory of natural selection as one of the epidemics which have swept the scientific world from time to time, and looked with absolute serenity to the return of science one day to the conception of creation by design.

Energy is an attribute of the higher races, being favoured beyond all other qualities by natural selection.

Cats are differentiated by natural selection until they have a power of hearing all the high notes made by mice and other little creatures that they have to catch.

Such being our habitual state of mind, it may well be believed that the perusal of the new book "On the Origin of Species by Means of Natural Selection" left an uncomfortable impression, in spite of its plausible and winning ways.

In all candor we must at least concede that such considerations suggest a genetic descent from the drift period down to the present, and allow time enoughif time is of any accountfor variation and natural selection to work out some appreciable results in the way of divergence into races or even into so-called species.

The nation's leader for the struggle seems to have been secured through a process of natural selection as had been the case a century earlier with Washington.

So he spoils Everything; for you know, you must admit, Subka, that war means natural selection, Survival of the fittest, don't you see?

Natural selection is a process in the course of which many compete and contend while only a few survive and mature.

The simple unaided operation of natural selection could never have resulted in the origination of the human race.

They have probably approached the critical point where variations in intelligence, always important, have come to be supremely important, so as to be seized by natural selection in preference to variations in physical constitution.

It was certainly of great significance that the particular race of mammals whose intelligence increased far enough to make it worth while for natural selection to work upon intelligence alone was the race which had developed hands and could manipulate things.

Was it natural selection that brought about the result?

Darwin used the term 'natural selection' because he thought he saw an analogy between the tendency of nature and the selective purposes of intelligent beings.

Even among animals there are certain processes which cannot be brought under natural selection.

After this long enquiry into the nature and scope of natural selection, we should be better prepared to understand the degree and kind of ethical significance which can be rightly assigned to the theory of evolution.

In other words, the process of natural selection can give us no canon at all for putting a value upon these various activities, or upon the way in which man adapts himself to these parts of his environment.

In the third place, the way in which the action of natural selection differs according to circumstances affects its ethical significance.

We are bound to ask, for instance, what principles can decide between those divergent tendencies brought to light by natural selection, between the conditions of success for the group and the conditions of success for the individual?
