Charles Darwin
Charles Robert Darwin, FRS FRGS FLS FZSwas an English naturalist and geologist, best known for his contributions to the science of evolution. He established that all species of life have descended over time from common ancestors, and in a joint publication with Alfred Russel Wallace introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in...

Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relationship to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring.
We will now discuss in a little more detail the Struggle for Existence.
... if variations useful to any organic being do occur, assuredly individuals thus characterized will have the best chance of being perserved in the struggle for life; and from the strong principle of inheritance they will tend to produce offsping similarly characterized. This principle of preservation, I have called, for the sake of brevity, Natural Selection.
In the survival of favoured individuals and races, during the constantly-recurring struggle for existence, we see a powerful and ever-acting form of selection.
The survival or preservation of certain favoured words in the struggle for existence is natural selection.
Nothing is easier than to admit in words the truth of the universal struggle for life, or more difficult--at least I have found it so--than constantly to bear this conclusion in mind.
Each organic being is striving to increase in a geometrical ratio . . . each at some period of its life, during some season of the year, during each generation or at intervals, has to struggle for life and to suffer great destruction . . . The vigorous, the healthy, and the happy survive and multiply.
As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected. From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.
In the struggle for survival, the fittest win out at the expense of their rivals because they succeed in adapting themselves best to their environment.
I could show fight on natural selection having done and doing more for the progress of civilization than you seem inclined to admit. Remember what risk the nations of Europe ran, not so many centuries ago of being overwhelmed by the Turks, and how ridiculous such an idea now is! The more civilised so-called Caucasian races have beaten the Turkish hollow in the struggle for existence. Looking to the world at no very distant date, what an endless number of the lower races will have been eliminated by the higher civilized races throughout the world.
Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such fine graduated organic chain; and this, perhaps, is the most obvious and serious objection which can be urged against the theory.
It is generally admitted that with woman the powers of intuition, of rapid perception and perhaps of imitation, are more strongly marked than in man: but some, at least, of these faculties are characteristic of the lower races, and therefore of a pas
The belief in God has often been advanced as not only the greatest but the most complete of all the distinctions between man and the lower animals. It is, however, impossible to maintain that this belief is instinctive in man. The idea of a universal and beneficent creator does not seem to arise in the mind of man until he has been elevated by long, continued culture.
There is something referred to as the 'Darwin industry' in science.
