Quotes & Sayings About Natural Selection

Since many traits can affect an individual's adaptation to it's environment (it's "fitness") natural selection can over eons sculpt an animal or plant into something that looks designed — Jerry A. Coyne

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

Though it accounts for only 2 percent of the body's mass, it uses up a fifth of all the oxygen we breathe, and it's where a quarter of all our glucose gets burned. The brain is the most energetically expensive piece of equipment in our body, and has been ruthlessly honed by natural selection to be efficient at the tasks for which it evolved. One might say that the whole point of our nervous system, from the sensory organs that feed information to the glob of neurons that interprets it, is to develop a sense of what is happening in the present and what will happen in the future, so that we can respond in the best possible way. Strip away the emotions, the philosophizing, the neuroses, and the dreams, and our brains, in the most reductive sense, are fundamentally prediction and planning machines. — Joshua Foer

Darwin's "strange inversion of reasoning" and Turing's equally revolutionary inversion were aspects of a single discovery: competence without comprehension. Comprehension, far from being a Godlike talent from which all design must flow, is an emergent effect of systems of uncomprehending competence: natural selection on the one hand, and mindless computation on the other. These twin ideas have been proven beyond a reasonable doubt, but they still provoke dismay and disbelief in some quarters, which I have tried to dispel in this chapter. Creationists are not going to find commented code in the inner workings of organisms, and Cartesians are not going to find an immaterial res cogitans "where all the understanding happens". — Daniel C. Dennett

In fact, nothing in science as a whole has been more firmly established by interwoven factual information, or more illuminating than the universal occurrence of biological evolution. Further, few natural processes have been more convincingly explained than evolution by the theory of natural selection, or as it has been popularly called, Darwinism. — E. O. Wilson

What marks the transition from non-sentient to sentient beings? A model of increasing complexity based on evolution through natural selection is simply a descriptive hypothesis, a kind of euphemism for "mystery," and not a satisfactory explanation. — Dalai Lama XIV

And yet, strange to say, now that the truth [of natural selection] is recognized by most cultivated people ... now more than ever, in the history of the world, are they doing all they can to further the survival of the unfittest. — Herbert Spencer

In the case of living machinery, the 'designer' is unconscious natural selection, the blind watchmaker. — Richard Dawkins

The secrets of evolution are death and time - the deaths of enormous numbers of lifeforms that were imperfectly adapted to the environment; and time for a long succession of small mutations. — Carl Sagan

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

Natural selection is daily and hourly scrutinizing, throughout the world, every variation, even the slightest; rejecting that which is bad, preserving and adding up all that is good; silently and insensibly working, whenever and wherever opportunity offers, at the improvement of each organic being. — Richard Dawkins

Why not? It's natural selection. Just like nature." I wrinkled my nose. "Boudas love this argument, because it gives them an excuse to do all the wrong things. 'I'm sorry I screwed your sister and got my penis stuck in your German shepherd. It's in my nature. I just couldn't help myself. — Ilona Andrews

We add that it would be all too easy to object that mutations have no evolutionary effect because they are eliminated by natural selection. Lethal mutations (the worst kind) are effectively eliminated, but others persist as alleles ... Mutants are present within every population, from bacteria to man. There can be no doubt about it. But for the evolutionist, the essential lies elsewhere: in the fact that mutations do not coincide with evolution. — Pierre-Paul Grasse

Nowhere was Darwin able to point to one bona fide case of natural selection having actually generated evolutionary change in nature ... Ultimately, the Darwinian theory of evolution is no more nor less than the great cosmogenic myth of the twentieth century. — Michael Denton

There is another human defect which the Law of Natural Selection has yet to remedy: When people of today have full bellies, they are exactly like their ancestors of a million years ago: very slow to acknowledge any awful troubles they may be in. Then is when they forget to keep a sharp lookout for sharks and whales. This was a particularly tragic flaw a million years ago, since the people who were best informed about the state of the planet, like *Andrew MacIntosh, for example, and rich and powerful enough to slow down all the waste and destruction going on, were by definition well fed. So everything was always just fine as far as they were concerned. — Kurt Vonnegut

Natural selection has duped us with an emotion that encourages group thinking. It is an emotion that makes us act as if for the good of the group; an emotion that brings pleasure, pride, or even thrills from coordinated group activity. — Mark Pagel

The basic formulation, or bare-bones mechanics, of natural selection is a disarmingly simple argument, based on three undeniable facts (overproduction of offspring, variation, and heritability) and one syllogistic inference (natural selection, or the claim that organisms enjoying differential reproductive success will, on average, be those variants that are fortuitously better adapted to changing local environments, and that these variants will then pass their favored traits to offspring by inheritance). — Stephen Jay Gould

In one of my latest conversations with Darwin he expressed himself very gloomily on the future of humanity, on the ground that in our modern civilization natural selection had no play, and the fittest did not survive. Those who succeed in the race for wealth are by no means the best or the most intelligent, and it is notorious that our population is more largely renewed in each generation from the lower than from the middle and upper classes. — Alfred Russel Wallace

Natural selection is just three factors - over-production, variation, and inheritance combined to produce adaptation to changing local environments. It's not a principle or progress; it's just a principle of local adaptation. You don't make better creatures in any cosmic sense; you make creatures that are better suited to the changing climates of their local habitats. — Stephen Jay Gould

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

The chemist Peter Atkins correctly observed, "Natural selection was a revolution and a stepping-stone to fame; so was relativity, and so was quantum theory. The sheer thrill of discovery is the spur to greater effort. All young scientists aspire to revolution." The same can't be said for theologians (Martin Luther is a rare exception), who either bear their heresies in silence or aspire only to trivial reinterpretations of church doctrine. — Jerry A. Coyne

Culture represents a novelty in the world of nature, and it could have added an effective, unifying edge to the forces of natural selection. — Richard Leakey

In giving rise to man, the evolutionary process has, apparently for the first and only time in the history of the Cosmos, become conscious of itself.
So, the Devil's Chaplain might conclude, Stand tall, Bipedal Ape. The shark may outswim you, the cheetah outrun you, the swift outfly you, the capuchin outclimb you, the elephant outpower you, the redwood outlast you. But you have the biggest gifts of all: the gift of understanding the ruthlessly cruel process that gave us all existence; the gift of revulsion against its implications; the gift of foresight - something utterly foreign to the blundering short-term ways of natural selection - and the gift of internalizing the very cosmos. — Richard Dawkins

The trick is: how do you talk about natural selection without implying the rigidity of law? We use it as almost an active participant, almost like a god. In fact, you could substitute the word 'god' for 'natural selection' in a lot of evolutionary writings and you'd think you were listening to a theologian. — Greg Graffin

Suffering is a byproduct of evolution by natural selection, an inevitable consequence that may worry us in our more sympathetic moments but cannot be expected to worry a tiger - even if a tiger can be said to worry about anything at all - and certainly cannot be expected to worry its genes. — Richard Dawkins

This fundamental subject of Natural Selection will be treated at some length in the fourth chapter; and we shall then see how Natural Selection almost inevitably causes much Extinction of the less improved forms of life and induces what I have called Divergence of Character. In the next chapter I shall discuss the complex and little known laws of variation and of correlation of growth. In the four succeeding chapters, the most apparent and gravest difficulties on the theory will be given: namely, first, the difficulties of transitions, or in understanding how a simple being or a simple organ can be changed and perfected into a highly developed being or elaborately constructed organ; secondly the subject of Instinct, or the mental powers of animals, thirdly, Hybridism, or the infertility of species and the fertility of varieties when intercrossed; and fourthly, the imperfection of the Geological Record. In — Charles Darwin

An argument often given for why Earth couldn't host another form of life is that once the life we know became established, it would have eliminated any competition through natural selection. But if another form of life were confined to its own niche, there would be little direct competition with regular life. — Paul Davies

In the absence of the great majority of guests, all manner of rumors came into the Shalimar Bagh, hooded and cloaked to shield themselves against the elements, and filled the empty places around the dastarkhans: cheap rumors from the gutter as well as fancy rumors claiming aristocratic parentage - an entire social hierarchy of rumor lounged against the bolsters, created by the mystery that enveloped everything like the blizzard. The rumors were veiled, shadowy, unclear, argumentative, often malicious. They seemed like a new species of living thing, and evolved according to the laws laid down by Darwin, mutating randomly and being subjected to the amoral winnowing processes of natural selection. The — Salman Rushdie

Unfortunately, the optimistic view that "classical civilization" handed down certain fundamental works that managed to include the knowledge contained in the lost writings has proved groundless. In fact, in the face of a general regression in the level of civilization, it's never the best works that will be saved through an automatic process of natural selection. — Lucio Russo

People are only animals, but special animals. Every animal has fought and killed to survive, even before the dinosaurs. We're the only ones that do it for fun. That's why I don't know about Darwinism. Supposedly evolution and natural selection are all about survival, but we haven't gotten smarter over the years, only more dangerous. — Kurt Vonnegut

Nobody today is nearly smart enough to make the sorts of weapons even the poorest nations had a million years ago. Yes, and they were being used all the time. During my lifetime, there wasn't a day when, somewhere on the planet, there weren't at least three wars going on. And the Law of Natural Selection was powerless to respond to such new technologies. No female of any species, unless maybe she was a rhinoceros, could expect to give birth to a baby who was fireproof, bombproof, or bulletproo — Kurt Vonnegut

In the last few decades, mankind has sinned terribly against the law of natural selection. We haven't just maintained life unworthy of life, we have even allowed it to multiply. — David Klinghoffer

Design in nature is but a concatenation of accidents, culled by natural selection until the result is so beautiful or effective as to seem a miracle of purpose. — Michael Pollan

The rather uncomfortable feeling most of us have when we're around snakes is evidence of how this ancient experience continues to influence us today. Throughout the long prehistory of our species and those that preceded it, snakes were a mortal threat. And so we learned our lesson. Others didn't, but that had a nasty habit of dying. So natural selection did its work and the rule
beware of snakes
was ultimately hardwired into every human brain. It's universal. Go anywhere on the planet, examine any culture. People are wary of snakes. Even if
as in the Arctic
there are no snakes. Our primate cousins shared our long experience and they feel the same way: Even monkeys raised in laboratories who have never seen a snake will back away at the sight of one. — Daniel Gardner

The lowest strata are reproducing too fast. Therefore ... they must not have too easy access to relief or hospital treatment lest the removal of the last check on natural selection should make it too easy for children to be produced or to survive; long unemployment should be a ground for sterilisation. — Julian Huxley

It may be said that natural selection is daily and hourly scrutinizing, throughout the world, every variation, even the slightest; rejecting that which is bad, preserving and adding up all that is good; silently and insensibly working, wherever and whenever opportunity offers, at the improvement of each organic being in relation to its organic and inorganic conditions of life. — Charles Darwin

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 almost inevitably causes much Extinction of the less improved forms of life and induces what I have called Divergence of Character. — Charles Darwin

As commonly practised, philosophy is the attempt to find good reasons for conventional beliefs'
'There is no mechanism of selection in the history of ideas akin to that of the natural selection of genetic mutations in evolution'
'Human knowledge is one thing, human well-being is another.There is no predetermined harmony between the two'
'In the struggle for life, the taste for truth is a luxury-or else a disability — John Gray

Natural selection acts only by the preservation and accumulation of small inherited modifications, each profitable to the preserved being; and as modern geology has almost banished such views as the excavation of a great valley by a single diluvial wave, so will natural selection banish the belief of the continued creation of new organic beings, or of any great and sudden modification in their structure. — Charles Darwin

When humanitarianism came into vogue, and the unsound were tended at public expense, this natural selection ceased. And since these unfortunates were incapable alike of prudence and of social responsibility, they procreated without restraint, and threatened to infect the whole species with their rottenness. — Olaf Stapledon

A deep understanding of Darwinism teaches us to be wary of the easy assumption that design is the only alternative to chance — Richard Dawkins

Mr. Darwin ... has failed to hold definitely before his mind the principle that the difference of sex, whatever it may consist in, must itself be subject to natural selection and to evolution. — Antoinette Brown Blackwell

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 acts solely by accumulating slight successive favorable variations, it can produce no great or sudden modification; it can act only by very short steps. — Charles Darwin

There is no mechanism of selection in the history of ideas akin to that of the natural selection of genetic mutations in evolution — John Gray

Modern humanism is the faith that through science humankind can know the truth- and to be free. But if Darwin's theory of natural selection is true this is impossible. The human mind serves evolutionary success, not truth. To think otherwise is to resurrect the pre-Darwinian error that humans are different from all other animals. (...) There is no mechanism of selection in the history of ideas akin to that of the natural selection of genetic mutations in evolution.(...) Among humans, the best deceivers are those who deceive themselves: 'we deceive ourselves in order to deceive others better'. A lover who promises eternal fidelity s more likely to be believed if he believes his promise himself; he is no more likely to keep his promise.(...) In a competition for mates, a well-developed capacity for self-deception is an advantage. — John Gray

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

Nature is a strong brand name. Everybody knew that. First thing, Nomenclature 101. Slap Natural on the package, you were golden. Those words on the package promise ease from metropolitan care, modern worries. And out here, if you opened things up, underneath the cellophane, what did you find inside? That fruit has splendid packaging, it has solid consumer awareness and is an animal favorite. Its seeds will be deposited in spoor miles away and its market dominance will increase. Splendid and beautiful petals are great advertising
the insects buzz and hop from all points every weekend to hit this flower-bed mall. Natural selection was market forces. In business, in the woods: what is necessary to the world will last. — Colson Whitehead

You put three facts together - that all organisms produce more offspring that can survive, that there's variation among organisms, and that at least some of that variation is inherited - and the syllogistic inference is natural selection. — Stephen Jay Gould

The forces which are working out the great scheme of perfect happiness, taking no account of incidental suffering, exterminate such sections of mankind as stand in their way, with the same sternness that they exterminate beasts of prey and herds of useless ruminants. — Herbert Spencer

If artificial selection can make such major changes in so short a period of time, what must natural selection, working over billions of years, be capable of? The answer is all the beauty and diversity of the biological world. Evolution is a fact, not a theory. — Carl Sagan

The very comprehensibility of the world points to an intelligence behind the world. Indeed, science would be impossible if our intelligence were not adapted to the intelligibility of the world. The match between our intelligence and the intelligibility of the world is no accident. Nor can it properly be attributed to natural selection, which places a premium on survival and reproduction and has no stake in truth or conscious thought. Indeed, meat-puppet robots are just fine as the output of a Darwinian evolutionary process. — William A. Dembski

We are moving from unconscious evolution through natural selection to conscious evolution by choice. — Barbara Marx Hubbard

It must be the duty of racial hygiene to be attentive to a more severe elimination of morally inferior human beings than is the case today ... We should literally replace all factors responsible for selection in a natural and free life ... In prehistoric times of humanity, selection for endurance, heroism, social usefulness, etc. was made solely by hostile outside factors. This role must be assumed by a human organization; otherwise, humanity will, for lack of selective factors, be annihilated by the degenerative phenomena that accompany domestication. — Konrad Lorenz

The origin of the human condition is best explained by the natural selection for social interaction - the inherited propensities to communicate, recognize, evaluate, bond, cooperate, compete, and from all these the deep warm pleasure of belonging to your own special group. — Edward O. Wilson

The only way in which Darwin's data made sense was to suppose that species battled for survival, and that evolution came when one slight adaptation of a species proved more successful than another in the battle: a process which he named 'natural selection'. There was nothing benevolent about the providence which watched over the process. Reason was served her notice as the handmaid of Christian revelation. — Diarmaid MacCulloch

The men may also not have known that their notions of beauty and feelings of attraction are deeply hardwired, steered in the right direction by programs carved by millions of years of natural selection. — David Eagleman

We have seen that in certain respects operant reinforcement resembles the natural selection of evolutionary theory. Just as genetic characteristics which arise as mutations are selected or discarded by their consequences, so novel forms of behavior are selected or discarded through reinforcement. — B.F. Skinner

It is good to keep in mind ... that nobody has ever succeeded in producing even one new species by the accumulation of micromutations. Darwin's theory of natural selection has never had any proof, yet it has been universally accepted. — Richard Goldschmidt

We are a biological species arising from Earth's biosphere as one adapted species among many; and however splendid our languages and cultures, however rich and subtle our minds, however vast our creative powers, the mental process is the product of a brain shaped by the hammer of natural selection upon the anvil of nature. — Edward O. Wilson

We no longer have natural selection. We have unnatural selection. Survival of the fittest has been replaced by survival of the fakest. — Maureen Dowd

Darwin's theory of evolution by natural selection is the only workable explanation that has ever been proposed for the remarkable fact of our own existence, indeed the existence of all life wherever it may turn up in the universe. — John Maynard Smith

Nothing drives progress like the imagination. The idea precedes the deed. The only exceptions are accidents and natural selection. — Theodore Levitt

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

Natural selection certainly operates. It explains how bacteria will gain antibiotic resistance; it will explain how insects get insecticide resistance, but it doesn't explain how you get bacteria or insects in the first place. — William A. Dembski

Evolution, thus, is merely contingent on certain processes articulated by Darwin: variation and selection. No longer is a fixed object transformed, as in transformational evolution, but an entirely new start is, so to speak, made in every generation. — Ernst W. Mayr

The fact that natural selection and evolution crafted essentially carbon and water into a mechanism that can think and be conscious means there's nothing in physics that says you cannot do that to a greater degree. — Neill Blomkamp

The idea that we were designed by our past was the principal insight of Charles Darwin. He was the first to realize that you can abandon divine creation of species without abandoning the argument from design. Every living thing is "designed" quite unconsciously by the selective reproduction of its own ancestors to suit a particular life-style. Human nature was as carefully designed by natural selection for the use of a social, bipedal, originally African ape as human stomachs were designed for the use of an omnivorous African ape with a taste for meat. — Matt Ridley

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

The Christians who engaged in infamous persecutions and shameful inquisitions were not evil men but misguided men. The churchmen who felt they had an edict from God to withstand the progress of science, whether in the form of a Copernican revolution or a Darwinian theory of natural selection, were not mischievous men but misinformed men. — Martin Luther King Jr.

Natural selection is not evolution. — Ronald Fisher

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

Natural selection based on the differential multiplication of variant types cannot exist before there is material capable of replicating itself and its own variations, that is, before the origination of specifically genetic material or gene-material. — Hermann Joseph Muller

Nowadays theologians aren't quite so straightforward as Paley. They don't point to complex living mechanisms and say that they are self-evidently designed by a creator, just like a watch. But there is a tendency to point to them and say 'It is impossible to believe' that such complexity, or such perfection, could have evolved by natural selection. Whenever I read such a remark, I always feel like writing 'Speak for yourself' in the margin. — Richard Dawkins

A totally blind process can by definition lead to anything; it can even lead to vision itself. — Jacques Monod

Here the contention is not just that the new Darwinian paradigm can help us realize whichever moral values we happen to choose. The claim is that the new paradigm can actually influence - legitimately - our choice of basic values in the first place. Some Darwinians insist that such influence can never be legitimate. What they have in mind is the naturalistic fallacy, whose past violation has so tainted their line of work. But what we're doing here doesn't violate the naturalistic fallacy. Quite the opposite. By studying nature - by seeing the origins of the retributive impulse - we see how we have been conned into committing the naturalistic fallacy without knowing it; we discover that the aura of divine truth surrounding retribution is nothing more than a tool with which nature - natural selection - gets us to uncritically accept its "values." Once this revelation hits norm, we are less likely to obey this aura, and thus less likely to commit the fallacy. — Robert Wright

Whatever one may think about the possibility of a designer, the prevailing doctrine - that the appearance of life from dead matter and its evolution through accidental mutation and natural selection to its present forms has involved nothing but the operation of physical law - cannot be regarded as unassailable. It is an assumption governing the scientific project rather than a well-confirmed scientific hypothesis. — Thomas Nagel

Incidental by-products of alterations in other traits? Belyaev strongly leaned toward the latter view, because of a phenomenon known as "pleiotropy": a single gene affecting multiple traits. Pleiotropy means that selection - whether natural or artificial - for one trait can affect many others. This is why evolutionary biologists make a distinction between selection for and selection of.9 — Anonymous

The underlying reason for convergence seems to be that all organisms are under constant scrutiny of natural selection and are also subject to the constraints of the physical and chemical factors that severely limit the action of all inhabitants of the biosphere. Put simply, convergence shows that in a real world not all things are possible. — Simon Conway Morris

During Darwin's lifetime, most working scientists came around to the view that evolution is a fact, but they argued about the importance of natural selection. One hundred and fifty years later, it has turned out that Darwin was essentially right on both counts, but his theory of natural selection left out a lot of details. Those details are still a subject of active research. There is no research, however, about whether evolution happens. That issue was settled over a century ago and is no longer an interesting scientific question. — Alan R. Rogers

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

I am convinced that natural selection has been the main but not exclusive means of modification. — Charles Darwin

It is hard to explain the huge variety of diatoms - a microorganism that has 100,000 species - in terms of natural selection. — John Tyler Bonner

What are the chances that we will one day discover that DNA has absolutely nothing to do with inheritance? They are effectively zero. — Sam Harris

One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die. — Charles Darwin

Natural selection is not an inflammatory phrase; evolution is. — Peter Agre

At this point, godless materialists might be cheering. If humans evolved strictly by mutation and natural selection, who needs God to explain us? To this, I reply: I do. The comparison of chimp and human sequences, interesting as it is, does not tell us what it means to be human. In my views, DNA sequence alone, even if accompanied by a vast trove of data on biological function, will never explain certain special human attributes, such as the knowledge of the Moral Law and the universal search for God. Freeing God from the burden of special acts of creation does not remove Him as the source of the things that make humanity special, and of the universe itself. It merely shows us something of how He operates. — Francis S. Collins

Artificial selection turned the wolf into the shepherd, and the wild grasses into wheat and corn. In fact, almost every plant and animal that we eat today was bred from a wild, less edible ancestor. If artificial selection can work such profound changes in only ten or fifteen thousand years, what can natural selection do operating over billions of years? The answer is all the beauty and diversity of life. — Neil DeGrasse Tyson

With highly civilised nations continued progress depends in a subordinate degree on natural selection; for such nations do not supplant and exterminate one another as do savage tribes. — Charles Darwin

I am aware that the conclusions arrived at in this work will be denounced by some as highly irreligious; but he who denounces them is bound to show why it is more irreligious to explain the origin of man as a distinct species by descent from some lower from, through the laws of variation and natural selection, than to explain the birth of the individual through the laws of ordinary reproduction. The birth both of the species and of the individual are equally parts of that grand sequence of events, which our minds refuse to accept as the result of blind chance. — Charles Darwin

Arteriosclerosis, removing people from active life when the period of maximum fertility has passed, is of benefit to the young if it relieves them of the care of parents, or brings them an inheritance as they enter adult life. . . . Any attempts to eradicate such a disease from the urban population will be frustrated by natural selection and the survival of more grandchildren in families with few grandparents. Those best fitted to survive in a world growing more urban are those who cease to require support as soon as their roles as parents have been completed. Atherosclerosis and hypertension are now the chief factors in determining that we do not overstay our allotted span of life too long. — Thomas H. Lee

It is natural selection that gives direction to changes, orients chance, and slowly, progressively produces more complex structures, new organs, and new species. Novelties come from previously unseen association of old material. To create is to recombine. — Francois Jacob

Although I insist that God has always had the power to intervene directly in nature to create new forms, I am willing to be per-suaded that He chose not to do so and instead employed secondary natural causes like random mutation and natural selection. — Phillip E. Johnson

Admonished for his lack of familiarity with twentieth century science, Sundar Singh said, 'What is science?' 'Natural selection and survival of the fittest,' he was told. 'Ah,' Sundar Singh replied, 'but I am more interested in divine selection and the survival of the unfit. — Sadhu Sundar Singh

This preservation of favourable individual differences and variations, and the destruction of those which are injurious, I have called Natural Selection, or the Survival of the Fittest. — Charles Darwin

The passion for playing chess is one of the most unaccountable in the world. It slaps the theory of natural selection in the face. It is the most absorbing of occupations. The least satisfying of desires. A nameless excrescence upon life. It annihilates a man. You have, let us say, a promising politician, a rising artist that you wish to destroy. Dagger or bomb are archaic and unreliable - but teach him, inoculate him with chess. — H.G.Wells

In the ensuing chapters, we will look in some detail at particular manifestations of the modern scientific ideology and the false paths down which it has led us. We will consider how biological determinism has been used to explain and justify inequalities within and between societies and to claim that those inequalities can never be changed. We will see how a theory of human nature has been developed using Darwin's theory of evolution by natural selection to claim that social organization is also unchangeable because it is natural. We will see how problems of health and disease have been located within the individual so that the individual becomes a problem for society to cope with rather than society becoming a problem for the individual. And we will see how simple economic relationships masquerading as facts of nature can drive the entire direction of biological research and technology. — Richard C. Lewontin

Quantitative work shows clearly that natural selection is a reality, and that, among other things, it selects Mendelian genes, which are known to be distributed at random through wild populations, and to follow the laws of chance in their distribution to offspring. In other words, they are an agency producing variation of the kind which Darwin postulated as the raw material on which selection acts. — John B. S. Haldane

When I see the moon on a clear night, I do say "blessed be" and I remind myself to be grateful to the universe that I happen to exist in such a lovely and wondrous world, even and especially as I can rattle on about magma cooling, abiogenesis, and natural selection. — Thomm Quackenbush
