Natural Selection Quotes

They believe civilization weakens natural selection. They do nature’s work so that we do not become a soft race.

Natural selection favors the forces of psychological denial. The individual benefits as an individual from his ability to deny the truth even though society as a whole, of which he is a part, suffers. Education can counteract the natural tendency to do the wrong thing, but the inexorable succession of generations requires that the basis for this knowledge be constantly refreshed.

Garrett Hardin

Darwin called such a process artificial, as opposed to natural, selection, but from the flower’s point of view, this is a distinction without a difference: individual plants in which a trait desired by either bees or Turks occurred wound up with more offspring.

Michael Pollan

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.

Charles Darwin

It is a strange fact, incidentally, that religious apologists love the anthropic principle. For some reason that makes no sense at all, they think it supports their case. Precisely the opposite is true. The anthropic principle, like natural selection, is an alternative to the design hypothesis. It provides a rational, design-free explanation for the fact that we find ourselves in a situation propitious to our existence.

Richard Dawkins

Natural selection eliminates and maybe maintains, but it doesn't create... Neo-Darwinists say that new species emerge when mutations occur and modify an organism. I was taught over and over again that the accumulation of random mutations led to evolutionary change [which] led to new species. I believed it until I looked for evidence.

Lynn Margulis

[E]very major religion today is a winner in the Darwinian struggle waged among cultures, and none ever flourished by tolerating its rivals.

Edward O. Wilson

...and specimens like this confirmed there had been some kind of divine rule in the universe because no natural selection process was up to the task of creating something like him. This was some god’s, somewhere’s, handiwork.

Nicole Williams

Life on earth evolved gradually beginning with one primitive life form – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.

Jerry A. Coyne

It is not always the magnitude of the differences observed between species that must determine specific distinctions, but the constant preservation of those differences in reproduction.

Jean-Baptiste Lamarck

Nature's stern discipline enjoins mutual help at least as often as warfare. The fittest may also be the gentlest.

Theodosius Dobzhansky

Might one not say that in the chance combination of nature's production, since only those endowed with certain relations of suitability could survive, it is no cause for wonder that this suitability is found in all species that exist today? Chance, one might say, produced an innumerable multitude of individuals; a small number turned out to be constructed in such fashion that the parts of the animal could satisfy its needs; in another, infinitely greater number, there was neither suitability nor order: all of the later have perished; animals without a mouth could not live, others lacking organs for reproduction could not perpetuate themselves: the only ones to have remained are those in which were found order and suitability; and these species, which we see today, are only the smallest part of what blind fate produced.

Pierre-Louis Moreau De Maupertuis

It is essential for genetic material to be able to make exact copies of itself; otherwise growth would produce disorder, life could not originate, and favourable forms would not be perpetuated by natural selection.

Maurice Wilkins

It is difficult to believe in the dreadful but quiet war lurking just below the serene facade of nature.

Charles Darwin

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

Natural selection is not the wind which propels the vessel, but the rudder which, by friction, now on this side and now on that, shapes the course.

Asa Gray

The embryological record is almost always abbreviated in accordance with the tendency of nature (to be explained on the principle of survival of the fittest) to attain her needs by the easiest means.

Francis Maitland Balfour

Animals have genes for altruism, and those genes have been selected in the evolution of many creatures because of the advantage they confer for the continuing survival of the species.

Lewis Thomas

It is not the organs—that is, the character and form of the animal's bodily parts—that have given rise to its habits and particular structures. It is the habits and manner of life and the conditions in which its ancestors lived that have in the course of time fashioned its bodily form, its organs and qualities.

Jean-Baptiste Lamarck

Evolution is an integration of matter and concomitant dissipation of motion during which the matter passes from an indefinite incoherent homogeneity to a definite coherent heterogeneity, and during which the retained motion undergoes a parallel transformation.

Herbert Spencer

Indeed, not all attacks—especially the bitter and ridiculing kind leveled at Darwin—are offered in good faith, but for practical purposes it is good policy to assume that they are.

Hans Selye

First LawIn every animal which has not passed the limit of its development, a more frequent and continuous use of any organ gradually strengthens, develops and enlarges that organ, and gives it a power proportional to the length of time it has been so used; while the permanent disuse of any organ imperceptibly weakens and deteriorates it, and progressively diminishes its functional capacity, until it finally disappears.Second LawAll the acquisitions or losses wrought by nature on individuals, through the influence of the environment in which their race has long been placed, and hence through the influence of the predominant use or permanent disuse of any organ; all these are preserved by reproduction to the new individuals which arise, provided that the acquired modifications are common to both sexes, or at least to the individuals which produce the young.

Jean-Baptiste Lamarck

In 1867, George Campbell, Duke of Argyll, had published The Reign of Law, a book that Darwin found deeply annoying. A supporter of Richard Owen, Campbell argued that while evolution (or "Development") might be observable in the fossil record, it was merely evidence of God's purpose. God, for example, would cause horses and oxen to evolve in time to meet human needs. The brightly colored plumage of birds, Campbell went on, were simply God's decorations of nature for humanity's enjoyment.

Jonathan Clements

The expression often used by Mr. Herbert Spencer of the Survival of the Fittest is more accurate, and is sometimes equally convenient.

Charles Darwin

Evolution is the law of policies: Darwin said it, Socrates endorsed it, Cuvier proved it and established it for all time in his paper on 'The Survival of the Fittest.' These are illustrious names, this is a mighty doctrine: nothing can ever remove it from its firm base, nothing dissolve it, but evolution.

Mark Twain

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

Natural selection is not only a parsimonious, plausible and elegant solution; it is the only workable alternative to chance that has ever been suggested. Intelligent design suffers from exactly the same objection as chance. It is simply not a plausible solution to the riddle of statistical improbability. And the higher the improbability, the more implausible intelligent design becomes. Seen clearly, intelligent design will turn out to be a redoubling of the problem. Once again, this is because the designer himself (/herself/itself) immediately raises the bigger problem of his own origin. Any entity capable of intelligently designing something as improbable as a Dutchman's Pipe (or a universe) would have to be even more improbable than a Dutchman's Pipe. Far from terminating the vicious regress, God aggravates it with a vengeance.

Richard Dawkins

...if an organised body is not in the situation and circumstances best adapted to its sustenance and propagation, then, in conceiving an indefinite variety among the individuals of that species, we must be assured, that, on the one hand, those which depart most from the best adapted constitution, will be the most liable to perish, while, on the other hand, those organised bodies, which most approach to the best constitution for the present circumstances, will be best adapted to continue, in preserving themselves and multiplying the individuals of their race.

James Hutton

Evidently neither cats nor dogs, nor other animals that listen to human music, were constituted for the appreciation of it, for it is not of the slightest use to them in the struggle for existence. Moreover, they and their organs of hearing were much older than man and his music. Their power of appreciating music is therefore an uncontemplated side-faculty of a hearing apparatus which has become on other grounds what we find it to be. So it is, I believe, with man. He has not acquired his musical hearing as such, but has received a highly developed organ of hearing by a process of selection, because it was necessary to him in the selective process ; and this organ of hearing happens also to be adapted to listening to music.

August Weismann

More about the selection theory: Jerne meant that the Socratic idea of learning was a fitting analogy for 'the logical basis of the selective theories of antibody formation': Can the truth (the capability to synthesize an antibody) be learned? If so, it must be assumed not to pre-exist; to be learned, it must be acquired. We are thus confronted with the difficulty to which Socrates calls attention in Meno [ ... ] namely, that it makes as little sense to search for what one does not know as to search for what one knows; what one knows, one cannot search for, since one knows it already, and what one does not know, one cannot search for, since one does not even know what to search for. Socrates resolves this difficulty by postulating that learning is nothing but recollection. The truth (the capability to synthesize an antibody) cannot be brought in, but was already inherent.

Niels Kaj Jerne

An example of such emergent phenomena is the origin of life from non-living chemical compounds in the oldest, lifeless oceans of the earth. Here, aided by the radiation energy received from the sun, countless chemical materials were synthesized and accumulated in such a way that they constituted, as it were, a primeval “soup.” In this primeval soup, by infinite variations of lifeless growth and decay of substances during some billions of years, the way of life was ultimately reached, with its metabolism characterized by selective assimilation and dissimilation as end stations of a sluiced and canalized flow of free chemical energy.

R.W. van Bemmelen

Natural selection is a mechanism for generating an exceedingly high degree of improbability.

Ronald A. Fisher

The tendency to variation in living beings, which all admitted as a matter of fact; the selective influence of conditions, which no one could deny to be a matter of fact, when his attention was drawn to the evidence; and the occurrence of great geological changes which also was matter of fact; could be used as the only necessary postulates of a theory of the evolution of plants and animals which, even if not at once, competent to explain all the known facts of biological science, could not be shown to be inconsistent with any.

Thomas Henry Huxley

The fundamental biological variant is DNA. That is why Mendel's definition of the gene as the unvarying bearer of hereditary traits, its chemical identification by Avery (confirmed by Hershey), and the elucidation by Watson and Crick of the structural basis of its replicative invariance, are without any doubt the most important discoveries ever made in biology. To this must be added the theory of natural selection, whose certainty and full significance were established only by those later theories.

Jacques Monod

When one ponders on the tremendous journey of evolution over the past three billion years or so, the prodigious wealth of structures it has engendered, and the extraordinarily effective teleonomic performances of living beings from bacteria to man, one may well find oneself beginning to doubt again whether all this could conceivably be the product of an enormous lottery presided over by natural selection, blindly picking the rare winners from among numbers drawn at random. [Nevertheless,] a detailed review of the accumulated modern evidence [shows] that this conception alone is compatible with the facts.

Jacques Monod

Even today a good many distinguished minds seem unable to accept or even to understand that from a source of noise natural selection alone and unaided could have drawn all the music of the biosphere. In effect natural selection operates upon the products of chance and can feed nowhere else; but it operates in a domain of very demanding conditions, and from this domain chance is barred. It is not to chance but to these conditions that evolution owes its generally progressive course, its successive conquests, and the impression it gives of a smooth and steady unfolding.

Jacques Monod

All organisms vary. It is in the highest degree improbable that any given variety should have exactly the same relations to surrounding conditions as the parent stock. In that case it is either better fitted (when the variation may be called useful), or worse fitted, to cope with them. If better, it will tend to supplant the parent stock; if worse, it will tend to be extinguished by the parent stock.If (as is hardly conceivable) the new variety is so perfectly adapted to the conditions that no improvement upon it is possible,—it will persist, because, though it does not cease to vary, the varieties will be inferior to itself.If, as is more probable, the new variety is by no means perfectly adapted to its conditions, but only fairly well adapted to them, it will persist, so long as none of the varieties which it throws off are better adapted than itself.On the other hand, as soon as it varies in a useful way, i.e. when the variation is such as to adapt it more perfectly to its conditions, the fresh variety will tend to supplant the former.

Thomas Henry Huxley

It is therefore scientifically correct to say that 'natural selection has been proved to be an agent of evolutionary change' - we can, in fact, prove it by doing. But it is totally illegitimate to claim that the discovery of this mechanism - natural selection - proves that the cause of evolution 'was automatic with no room for divine guidance or design'.

Ernst F. Schumacher

The arms race between [predators] and [prey] is asymmetric, in which success on either side is felt as failure by the other side, but the nature of the success and failure on the two sides is very different. The two sides are 'trying' to do very different things. [Predators] are trying to eat [prey]. [Prey] are not trying to eat [predators], they are trying to avoid being eaten by [predators].From an evolutionary point of view asymmetric arms races are more [likely] to generate highly complex weapons systems.

Richard Dawkins

He who believes that each being has been created as we now see it, must occasionally have felt surprise when he has met with an animal having habits and structure not at all in agreement.

Charles Darwin

Evolution has no long-term goal. There is no long-distance target, no final perfection to serve as a criterion for selection, although human vanity cherishes the absurd notion that our species is the final goal of evolution.

Richard Dawkins

Oxygen flooded into the atmosphere as a pollutant, even a poison, until natural selection shaped living things to thrive on the stuff and, indeed, suffocate without it.

Richard Dawkins

George Williams, the revered evolutionary biologist, describes the natural world as “grossly immoral.” Having no foresight or compassion, natural selection “can honestly be described as a process for maximizing short-sighted selfishness.” On top of all the miseries inflicted by predators and parasites, the members of a species show no pity to their own kind. Infanticide, siblicide, and rape can be observed in many kinds of animals; infidelity is common even in so-called pair-bonded species; cannibalism can be expected in all species that are not strict vegetarians; death from fighting is more common in most animal species than it is in the most violent American cities. Commenting on how biologists used to describe the killing of starving deer by mountain lions as an act of mercy, Williams wrote: “The simple facts are that both predation and starvation are painful prospects for deer, and that the lion's lot is no more enviable. Perhaps biology would have been able to mature more rapidly in a culture not dominated by Judeo-Christian theology and the Romantic tradition. It might have been well served by the First Holy Truth from [Buddha's] Sermon at Benares: “Birth is painful, old age is painful, sickness is painful, death is painful...”” As soon as we recognize that there is nothing morally commendable about the products of evolution, we can describe human psychology honestly, without the fear that identifying a “natural” trait is the same as condoning it. As Katharine Hepburn says to Humphrey Bogart in The African Queen, “Nature, Mr. Allnut, is what we are put in this world to rise above.

Steven Pinker

People who are depressed at the thought that all our motives are selfish are [confused]. They have mixed up ultimate causation (why something evolved by natural selection) with proximate causation (how the entity works here and now). [A] good way to understand the logic of natural selection is to imagine that genes are agents with selfish motives. [T]he genes have metaphorical motives — making copies of themselves — and the organisms they design have real motives. But they are not the same motives. Sometimes the most selfish thing a gene can do is wire unselfish motives into a human brain — heartfelt, unstinting, deep-in-the-marrow unselfishness. The love of children (who carry one's genes into posterity), a faithful spouse (whose genetic fate is identical to one's own), and friends and allies (who trust you if you're trustworthy) can be bottomless and unimpeachable as far as we humans are concerned (proximate level), even if it is metaphorically self-serving as far as the genes are concerned (ultimate level). Combine this with the common misconception that the genes are a kind of essence or core of the person, and you get a mongrel of Dawkins and Freud: the idea that the metaphorical motives of the genes are the deep, unconscious, ulterior motives of the person. That is an error.

Steven Pinker

Nothing at first can appear more difficult to believe than that the more complex organs and instincts should have been perfected, not by means superior to, though analogous with, human reason, but by the accumulation of innumerable slight variations, each good for the individual possessor. Nevertheless, this difficulty, though appearing to our imagination insuperably great, cannot be considered real if we admit the following propositions, namely,— that gradations in the perfection of any organ or instinct, which we may consider, either do now exist or could have existed, each good of its kind,— that all organs and instincts are, in ever so slight a degree, variable,— and, lastly, that there is a struggle for existence leading to the preservation of each profitable deviation of structure or instinct. The truth of these propositions cannot, I think, be disputed.

Charles Darwin

Perhaps the most legitimately dispiriting thing about reciprocal altruism is that it is a misnomer. Whereas with kin selection the "goal" of our genes is to actually help another organism, with reciprocal altruism the goal is that the organism be left under the impression that we've helped; the impression alone is enough to bring the reciprocation.

Robert Wright

It looks as if the offspring have eyes so that they can see well (bad, teleological, backward causation), but that's an illusion. The offspring have eyes because their parents' eyes did see well (good, ordinary, forward causation).

Steven Pinker

Things exist either because they have recently come into existence or because they have qualities that made them unlikely to be destroyed in the past.

Richard Dawkins

It wasn't torpor that kept her - she was often restless to the point of irritability. She simply liked to feel that she was prevented from leaving, that she was needed.

Ian McEwan

There was something built into the human brain by natural selection which was once useful, and which now manifests itself as religion.

Richard Dawkins

Any species that devours its natural environment will eventually fall victim to the resulting silence and I call the toxicity of silence: Extinction Silence

Steven Magee

The human skin evolved in a natural electromagnetic radiation environment and is now in a very unnatural man-made one that is making many people sick.

Steven Magee

The human has genetic adaptation to natural electromagnetic radiation. Increasing, reducing or removing the natural radiation exposures results in a sickened human that may progress onto a diseased state.

Steven Magee

If theft is advantageous to everyone who succeeds at it, and adultery is a good strategy, at least for males, for increasing presence in the gene pool, why do we feel they are wrong? Shouldn't the only morality that evolution produces be the kind Bill Clinton had - being sorry you got caught?

Robert J. Sawyer

In microbiology the roles of mutation and selection in evolution are coming to be better understood through the use of bacterial cultures of mutant strains.

Edward Tatum

Historians will have to face the fact that natural selection determined the evolution of cultures in the same manner as it did that of species.

Konrad Lorenz

While a number of people have pointed out the various costs and drawbacks of sentience, few if any have taken the next step and wondered out loud if the whole damn thing isn't more trouble than it's worth. Of course it is, people assume; otherwise natural selection would have weeded it out long ago. And they're probably right. I hope they are. "Blindsight" is a thought experiment, a game of "Just suppose" and "What if". Nothing more.On the other hand, the dodos and the Steller sea cows could have used exactly the same argument to prove their own superioirity, a thousand years ago: "if we're so unfit, why haven't we gone extinct?" Why? Because natural selection takes time, and luck plays a role. The biggest boys on the block at any given time aren't necessarily the fittest, or the most efficient, and the game isn't over. The game is never over; there's no finish line this side of heat death. And so, neither can there be any winners. There are only those who haven't yet lost.

Peter Watts

Nature might be a great experimentalist, but one who would never pass muster with an ethics review board – contravening the Helsinki Declaration and every norm of moral decency, left, right, and center.

Nick Bostrom

I'm an Atheist. I don't believe in God, Gods, Godlets or any sort of higher power beyond the universe itself, which seems quite high and powerful enough to me. I don't believe in life after death, channeled chat rooms with the dead, reincarnation, telekinesis or any miracles but the miracle of life and consciousness, which again strike me as miracles in nearly obscene abundance. I believe that the universe abides by the laws of physics, some of which are known, others of which will surely be discovered, but even if they aren't, that will simply be a result, as my colleague George Johnson put it, of our brains having evolved for life on this one little planet and thus being inevitably limited. I'm convinced that the world as we see it was shaped by the again genuinely miraculous, let's even say transcendent, hand of evolution through natural selection.

Natalie Angier

In the distant future I see open fields for far more important researches. Psychology will be based on a new foundation, that of the necessary acquirement of each mental power and capacity by gradation. Light will be thrown on the origin of man and his history.
