Alfred Wallace Evolution Quotes & Sayings

I fully agree with all that you say on the advantages of H. Spencer's excellent expression of 'the survival of the fittest.' This, however, had not occurred to me till reading your letter. It is, however, a great objection to this term that it cannot be used as a substantive governing a verb; and that this is a real objection I infer from H. Spencer continually using the words, natural selection.
(Letter to A. R. Wallace July 1866) — Charles Darwin

The publication of the Darwin and Wallace papers in 1858, and still more that of the 'Origin' in 1859, had the effect upon them of the flash of light, which to a man who has lost himself in a dark night, suddenly reveals a road which, whether it takes him straight home or not, certainly goes his way. That which we were looking for, and could not find, was a hypothesis respecting the origin of known organic forms, which assumed the operation of no causes but such as could be proved to be actually at work. We wanted, not to pin our faith to that or any other speculation, but to get hold of clear and definite conceptions which could be brought face to face with facts and have their validity tested. The 'Origin' provided us with the working hypothesis we sought. — Thomas Henry Huxley

This survival of the fittest implies multiplication of the fittest.

{The phrase 'survival of the fittest' was not originated by Charles Darwin, though he discussed Spencer's 'excellent expression' in a letter to Alfred Russel Wallace (Jul 1866).} — Herbert Spencer

There is a great deal more to evolutionary biology than survival of the fittest - although that's all anyone seems to remember. One of Darwin's contemporaries was Alfred Russel Wallace, who had even more profound lessons about evolution - that humans are social creatures. That we coevolve with other species as part of a fabric of interwoven and interdependent life-forms. The world isn't entirely about competition and dominance. And species that cooperate with others succeed better than those who do not. That's what civilization is, cooperation." "And — Daniel Suarez

There might have been a hundred or a thousand life-bearing planets, had the course of evolution of the universe been a little different, or there might have been none at all. They would probably add, that, as life and man have been produced, that shows that their production was possible; and therefore, if not now then at some other time, if not here then in some other planet of some other sun, we should be sure to have come into existence; or if not precisely the same as we are, then something a little better or a little worse. — Alfred Russel Wallace

The facts of variability, of the struggle for existence, of adaptation to conditions, were notorious enough; but none of us had suspected that the road to the heart of the species problem lay through them, until Darwin and Wallace dispelled the darkness. — Thomas Henry Huxley
