Darwin Species Quotes & Sayings

As the species of the same genus usually have, though by no means invariably, much similarity in habits and constitution, and always in structure, the struggle will generally be more severe between them, if they come into competition with each other, than between the species of distinct genera. — Charles Darwin

I am actually weary of telling people that I do not pretend to adduce [direct] evidence of one species changing into another, but I believe that this view is in the main correct, because so many phenomena can thus be grouped end explained. — Charles Darwin

It has sometimes been said that the success of the Origin proved "that the subject was in the air," or "that men's minds were prepared for it." I do not think that this is strictly true, for I occasionally sounded not a few naturalists, and never happened to come across a single one who seemed to doubt about the permanence of species. — Charles Darwin

It was in the attempt to ascertain the interrelationships between species that experiments n genetics were first made. The words "evolution" and "origin of species" are now so intimately associated with the name of Darwin that we are apt to forger that the idea of common descent had been prominent in the mnds of naturalists before he wrote, and that, for more than half a century, zealous investigators had been devoting themselves to the experimental study of that possibility. Prominent among this group of experimenters may be mentioned Koelreauter, John Hunter, Herbert Knight, Gartner, Jordan. Naudin, Godron, Lecoq, Wichura
men whose names are familiar to every reader of Animals and Plants unders Domestication. — William Bateson

In 186 species showing that a huge variety of male traits are correlated with mating success, and the vast majority of these tests involve female choice. There is simply no doubt that female choice has driven the evolution of many sexual dimorphisms. Darwin was right after all. So far we've neglected two important questions: Why do females get to do the choosing while males must woo or fight for them? And why do females choose at all? To answer these questions we must first understand why organisms bother to have sex. — Jerry A. Coyne

Great as the differences are between the breeds of pigeons, I am fully convinced that the common opinion of naturalists is correct, namely, that all have descended from the rock-pigeon (Columba livia), including under this term several geographical races or sub-species, which differ from each other in the most trifling respects. — Charles Darwin

All disciplines of science are built on the causality of the relationships governing related events. Yet the theory of evolution is built upon the idea of accidental changes that resulted in complex living systems. I was unable to comprehend how the notion that an infinite number of random accidents systematically happened to produce living species, and kept improving these beings, is justified. — T.H. Janabi

The formation of different languages and of distinct species and the proofs that both have been developed through a gradual process, are curiously parallel. — Charles Darwin

Paleontologists had long been aware of a seeming contradiction between Darwin's postulate of gradualism, confirmed by the work of population genetics, and the actual findings of paleontology. Following phyletic lines through time seemed to reveal only minimal gradual changes but no clear evidence for any change of a species into a different genus or for the gradual origin of an evolutionary novelty. Anything truly novel always seemed to appear quite abruptly in the fossil record. — Ernst Mayr

We behold the face of nature bright with gladness. — Charles Darwin

Causes of Variability - Effects of Habit and the use and disuse of Parts - Correlated Variation - Inheritance - Character of Domestic Varieties - Difficulty of distinguishing between Varieties and Species - Origin of Domestic Varieties from one or more Species - Domestic Pigeons, their Differences and Origin - Principles of Selection, anciently followed, their Effects - Methodical and Unconscious Selection - Unknown Origin of our Domestic Productions - Circumstances favourable to Man's power of Selection. — Charles Darwin

Paleontologists ever since Darwin have been searching (largely in vain) for the sequences of insensibly graded series of fossils that would stand as examples of the sort of wholesale transformation of species that Darwin envisioned as the natural product of the evolutionary process. Few saw any reason to demur - though it is a startling fact that ... most species remain recognizably themselves, virtually unchanged throughout their occurrence in geological sediments of various ages. — Niles Eldredge

Nevertheless it is probable that the hearing rather early in life such views maintained and praised may have favoured my upholding them under a different form in my 'Origin of Species. — Charles Darwin

When Charles Darwin published On the Origin of Species in 1859, he exposed the world to a momentous discovery . For the first time in history, human beings were seen not as creatures of divine origin, but instead, as a product of nature, an animal like every other on the planet. Imagine yourself back in that amazing year. The day before Darwin's book was published, you wake up thinking yourself the image of God; the next morning you realize you have the face of a monkey. Not everybody immediately embraced this rude demotion from god to goat. — Jeff Schweitzer

From a ball of mud taken from a birds plumage, Charles Darwin raised 82 separate plants, belonging to five distinct species! — Rachel Carson

It is not the strongest of the species that survives, not the most intelligent that survives. It is the one that is the most adaptable to change. - Charles Darwin — Aleatha Romig

It is really laughable to see what different ideas are prominent in various naturalists' minds, when they speak of 'species'; in some, resemblance is everything and descent of little weight-in some, resemblance seems to go for nothing, and Creation the reigning idea-in some, descent is the key,-in some, sterility an unfailing test, with others it is not worth a farthing. It all comes, I believe, from trying to define the undefinable. — Charles Darwin

Let's find and remedy all our weaknesses before our enemies get a chance to say a word. That is what Charles Darwin did ... When Darwin completed the manuscript of his immortal book "The Origin Of Species" he realized that the publication of his revolutionary concept of creation would rock the intellectual and religious worlds. So he became his own critic and spent another 15 years checking his data, challenging his reasoning, and criticizing his conclusions. — Dale Carnegie

I am a big believer of what Darwin discovered in the Galapagos, proving that the species most responsive to change will survive over apparently stronger or more intelligent competitors. — John Elkann

I quoted to him what I remembered of Charles Darwin: "'Judging by the past, we may safely infer that not one living species will transmit its unaltered likeness to a distant futurity ... '"
"Darwin was right," Nebogipfel said gently. — Stephen Baxter

The number of living creatures of all orders whose existence intimately depends on kelp is wonderful. A great volume might be written describing the inhabitants of one of these beds of seaweed ... . I can only compare these great aquatic forests ... with terrestrial ones in the intertropical regions. Yet, if in any other country a forest was destroyed, I do not believe so many species of animals would perish as would here, from the destruction of kelp — Charles Darwin

I think it inevitably follows, that as new species in the course of time are formed through natural selection, others will become rarer and rarer, and finally extinct. The forms which stand in closest competition with those undergoing modification and improvement will naturally suffer most. — Charles Darwin

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

A grain in the balance will determine which individual shall live and which shall die - which variety or species shall increase in number, and which shall decrease, or finally become extinct. — Charles Darwin

A language, like a species, when extinct, never ... reappears. — Charles Darwin

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

The most powerful natural species are those that adapt to environmental change without losing their fundamental identity which gives them their competitive advantage. — Charles Darwin

I am almost convinced (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable. — Charles Darwin

We here see in two distant countries a similar relation between plants and insects of the same families, though the species of both are different. When man is the agent in introducing into a country a new species this relation is often broken: — Charles Darwin

Mere chance ... alone would never account for so habitual and large an amount of difference as that between varieties of the same species. — Charles Darwin

On the ordinary view of each species having been independently created, we gain no scientific explanation. — Charles Darwin

I have always thought that Darwin was wrong: his theory doesn't account for all this variety of species. It hasn't the necessary multiplicity. Nowadays some people are fond of saying that at last evolution has produced a species that is able to understand the whole process which gave it birth. Now that you can't say.
[Drury, Conversation with Wittgenstein, p174] — Ludwig Wittgenstein

This was the scientific age, and people wanted to believe that their traditions were in line with the new era, but this was impossible if you thought that these myths should be understood literally. Hence the furor occasioned by The Origin of Species, published by Charles Darwin. The book was not intended as an attack on religion, but was a sober exploration of a scientific hypothesis. But because by this time people were reading the cosmogonies of Genesis as though they were factual, many Christians felt
and still feel
that the whole edifice of faith was in jeopardy. Creation stories had never been regarded as historically accurate; their purpose was therapeutic. But once you start reading Genesis as scientifically valid, you have bad science and bad religion. — Karen Armstrong

Now when naturalists observe a close agreement in numerous small details of habits, tastes and dispositions between two or more domestic races, or between nearly-allied natural forms, they use this fact as an argument that all are descended from a common progenitor who was thus endowed; and consequently that all should be classed under the same species. The same argument may be applied with much force to the races of man. — Charles Darwin

It has already been stated that various parts in the same individual, which are exactly alike during an early embryonic period, become widely different and serve for widely different purposes in the adult state. So again it has been shown that generally the embryos of the most distinct species belonging to the same class are closely similar, but become, when fully developed, widely dissimilar. — 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

There's a voice that says: "So what?"
It's not my voice, it's probably not yours, but it makes itself heard in the arenas of public opinion, querulous and smug and fortified by just a little knowledge, which as always is a dangerous thing. "So what if a bunch of species go extinct?" It says. "Extinction is a natural process. Darwin himself said so, didn't he? Extinction is the complement of evolution, making room for new species to evolve. There have always been extinctions. So why worry about these extinctions currently being caused by humanity?" And there has always been a pilot light burning in your furnace. So why worry when your house is on fire? — David Quammen

Hereafter we shall be compelled to acknowledge that the only distinction between species and well-marked varieties is, that the latter are known, or believed to be connected at the present day by intermediate gradations whereas species were formerly thus connected. — Charles Darwin

Judging from the past, we may safely infer that not one living species will transmit its unaltered likeness to a distant futurity. — Charles Darwin

It was evident that such facts as these, as well as many others, could only be explained on the supposition that species gradually become modified; and the subject haunted me. — Charles Darwin

The starting point of Darwin's theory of evolution is precisely the existence of those differences between individual members of a race or species which morphologists for the most part rightly neglect. The first condition necessary, in order that any process of Natural Selection may begin among a race, or species, is the existence of differences among its members; and the first step in an enquiry into the possible effect of a selective process upon any character of a race must be an estimate of the frequency with which individuals, exhibiting any given degree of abnormality with respect to that, character, occur. The unit, with which such an enquiry must deal, is not an individual but a race, or a statistically representative sample of a race; and the result must take the form of a numerical statement, showing the relative frequency with which the various kinds of individuals composing the race occur. — Karl Pearson

For more than a century, people have often thought that the conclusion to draw from Darwin's vision is that Homo sapiens, our species - and we're just animals too, we're just mammals - that there is nothing morally special about us. I myself don't think this follows at all from Darwin's vision, but it is certainly the received view in many quarters. — Daniel Dennett

I can entertain no doubt, after the most deliberate study and dispassionate judgment of which I am capable, that the view which most naturalists entertain, and which I formerly entertained - namely, that each species has been independently created - is erroneous. — Charles Darwin

The observation that species are amazingly conservative and static entities throughout long periods of time has all the qualities of the emperor's new clothes: everyone knew it but preferred to ignore it. Paleontologists, faced with a recalcitrant record obstinately refusing to yield Darwin's predicted pattern, simply looked the other way. — Niles Eldredge

I see no good reason why the views given this volume [The Origin of Species] should shock the religious feelings of any one. It is satisfactory, as showing how transient such impressions are, to remember that the greatest discovery ever made by man, namely, the law of attraction of gravity, was also attacked by Leibnitz, 'as subversive of natural, and inferentially of revealed, religion.' — Charles Darwin

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

The idea that one can go to the fossil record and expect to empirically recover an ancestor-descendant sequence, be it of species, genera, families, or whatever, has been, and continues to be, a pernicious illusion. — Gareth J. Nelson

Darwin abolished special creations, contributed the Origin of Species and hitched all life together in one unbroken procession. — Mark Twain

Why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms. — Charles Darwin

I do not believe, as we shall presently see, that all our dogs have descended from any one wild species; but, in the case of some other domestic races, there is presumptive, or even strong, evidence in favour of this view. — Charles Darwin

It is not the most intellectual of the species that survives; it is not the strongest that survives; but the species that survives is the one that is able best to adapt and adjust to the changing environment in which it finds itself. — Charles Darwin

Species that struggle to adapt to survive will become extinct — Charles Darwin

he was at heart profoundly conservative and would not keep the works of Darwin or Lyell in his study for fear they carried a contagion that might spread throughout his healthier books. He was not an especially devout man, but felt that a common faith overlooked by a benevolent God was what kept the fabric of society from tearing like a worn sheet. The idea that after all there was no essential nobility in mankind, and that his own species was not a chosen people touched by the divine, troubled him in the hours before dawn; and as with most troubling matters he elected to ignore it, until it went away. — Sarah Perry

Mr. Charles Darwin, who looked a bit like God which is interesting, wrote a book called You're a Fucking Monkey, Mate. He played around with the title for a while: We're All Fucking Monkeys; You're a Fucking Monkey, Mate; Get Out of My Face, You Fucking Monkey. And he ended up with On The Origin of Species. — Eddie Izzard

[ ... ] it is a strange thing that most of the feeling we call religious, most of the mystical outcrying which is one of the most prized and used and desired reactions of our species, is really the understanding and the attempt to say that man is related to the whole thing, related inextricably to all reality, known and unknowable. This is a simple thing to say, but the profound feeling of it made a Jesus, a St. Augustine, a St. Francis, a Roger Bacon, a Charles Darwin, and an Einstein. Each of them in his own tempo and with his own voice discovered and reaffirmed with astonishment the knowledge that all things are one thing and that one thing is all things - plankton, a shimmering phosphorescence on the sea and the spinning planets and an expanding universe, all bound together by the elastic string of time. It is advisable to look from the tide pool to the stars and then back to the tide pool again. — John Steinbeck

Among the things most characteristic of organisms--most distinctive of living as opposed to inorganic systems--is a sort of directedness. Their structures and activities have an adaptedness, an evident and vital usefulness to the organism. Darwin's answer and ours is to accept the common sense view...[that] the end ("telos") [is] that the individual and the species may survive. But this end is (usually) unconscious and impersonal. Naive teleology is controverted not by ignoring the obvious existence of such ends but by providing a naturalistic, materialistic explanation of the adaptive characteristics serving them. [Book review in "Science," 1959, p. 673.] — George Gaylord Simpson

It occurred to me, in 1837, that something might perhaps be made of this question (the origin of the species) by patiently accumulating and reflecting on all sorts of facts which could possibly have any bearing on it — Charles Darwin

The wide-ranging birds that visit islands of the ocean in migration may also have a good deal to do with the distribution of plants, and perhaps even of some insects and minute land shells. From a ball of mud taken from a bird's plumage, Charles Darwin raised 82 separate plants, belonging to 5 distinct species! Many plant seeds have hooks or prickles, ideal for attachment to feathers. Such birds as the Pacific golden plover, which annually flies from the mainland of Alaska to the Hawaiian Islands and even beyond, probably figure in many riddles of plant distribution. — Rachel Carson

Species do not grow more perfect: the weaker dominate the strong, again and again- the reason being that they are the great majority, and they are also cleverer. Darwin forgot the mind (-that is English!): the weak possess more mind ... To acquire mind, one must need mind-one loses it when one no longer needs it. — Friedrich Nietzsche

I am above the forest region, amongst grand rocks & such a torrent as you see in Salvator Rosa's paintings vegetation all a scrub of rhodos. with Pines below me as thick & bad to get through as our Fuegian Fagi on the hill tops, & except the towering peaks of P. S. [perpetual snow] that, here shoot up on all hands there is little difference in the mt scenery - here however the blaze of Rhod. flowers and various colored jungle proclaims a differently constituted region in a naturalist's eye & twenty species here, to one there, always are asking me the vexed question, where do we come from?
[Letter to Charles Darwin 24 Jun 1849] — Joseph Dalton Hooker

If it is true that an influx of doubt and uncertainty actually marks periods of healthy growth in a science, then evolutionary biology is flourishing today as it seldom has flourished in the past. For biologists collectively are less agreed upon the details of evolutionary mechanics than they were a scant decade ago. Superficially, it seems as if we know less about evolution than we did in 1959, the centennial year of Darwin's on the Origin of Species. — Niles Eldredge

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

At last gleams of light have come, and I am almost convinced (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable. Heaven forfend me from Lamarck nonsense of a 'tendency to progression', 'adaptations from the slow willing of animals', &c! But the conclusions I am led to are not widely different from his; though the means of change are wholly so. I think I have found out (here's presumption!) the simple way by which species become exquisitely adapted to various ends. — Charles Darwin

I have just finished my sketch of my species theory. If as I believe that my theory is true & if it be accepted even by one competent judge, it will be a considerable step in science. I therefore write this, in case of my sudden death, as my most solemn & last request, which I am sure you will consider the same as if legally entered in my will, that you will devote 400£ to its publication & further will yourself, or through Hensleigh [Wedgwood], take trouble in promoting it. — Charles Darwin

When Charles Darwin wrote The Origin Of The Species, no one could have known that the ice cap would melt, that the waters would rise and that life on earth would have to evolve in order to live beneath the sea once more or perish. We came from water and now, with the help of stem cell technology and cloning, we must go back to it to survive.When the waters rise, humanity will go back to the place from whence it came.Make no mistake, this is not sci-fi, this is evolution — Alexander McQueen

Seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends. — 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

Over the past 10,000 years, Homo sapiens has grown so accustomed to being the only human species that it's hard for us to conceive of any other possibility. Our lack of brothers and sisters makes it easier to imagine that we are the epitome of creation, and that a chasm separates us from the rest of the animal kingdom. When Charles Darwin indicated that Homo sapiens was just another kind of animal, people were outraged. Even today many refuse to believe it. Had the Neanderthals survived, would we still imagine ourselves to be a creature apart? Perhaps this is exactly why our ancestors wiped out the Neanderthals. They were too familiar to ignore, but too different to tolerate. Whether — Yuval Noah Harari

The law of evolution is that the strongest survives!' 'Yes, and the strongest, in the existence of any social species, are those who are most social. In human terms, most ethical ... There is no strength to be gained from hurting one another. Only weakness. — Ursula K. Le Guin

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. — Charles Darwin

Darwin's dice have rolled badly for Earth. The human species is, in a word, an environmental abnormality. Perhaps a law of evolution is that intelligence usually extinguishes itself. — E. O. Wilson

That which struck the present writer most forcibly on his first perusal of the 'Origin of Species' was the conviction that Teleology, as commonly understood, had received its deathblow at Mr. Darwin's hands. For the teleological argument runs thus: an organ or organism (A) is precisely fitted to perform a function or purpose (B); therefore it was specially constructed to perform that function. — Thomas Henry Huxley

It takes a long time before we really get to grips with this [Darwin's 'On the Origin of Species'] and begin to understand it, because not only does it seem incredible and thoroughly demeaning to us, but it's yet another shock to our system to discover that not only are we not the centre of the Universe and we're not made by anything, but we started out as some kind of slime and got to where we are via being a monkey. It just doesn't read well. — Douglas Adams

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

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

I have stated, that in the thirteen species of ground-finches, a nearly perfect gradation may be traced, from a beak extraordinarily thick, to one so fine, that it may be compared to that of a warbler. — Charles Darwin

Intelligence is based on how efficient a species became at doing the things they need to survive. — Charles Darwin

I love to read, and so I've been reading everything I can, not intensely, but I love to read so I read "Origin of Species" by Darwin and I can't make head or tail of E=MC squared by Einstein, but I try to baffle my way through that. — Anthony Hopkins

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. — Charles Darwin

The key word is flexibility, the ability to adapt constantly. Darwin said it clearly. People thought that he mainly talked about survival of the fittest. What he said was that the species that survive are usually not the smartest or the strongest, but the ones most responsive to change. So being attentive to customers and potential partners is my best advice
after, of course, perseverance and patience. — Philippe Kahn

When most of us hear the phrase, 'survival of the fittest,' we assume it originated with Charles Darwin. It did not. The phrase doesn't exist anywhere in Darwin's first edition of 'Origin of the Species.' — Joel A. Barker

As Darwin himself was at pains to point out, natural selection is all about differential survival within species, not between them. — Richard Dawkins

Elgin himself looked ten years younger, now that he'd cast the die, but I thought exuberance had got the better of him when he strode into the saloon later, threw The Origin of Species on the table and announced:
"It's very original, no doubt, but not for a hot evening. What I need is some trollop."
I couldn't believe my ears, and him a church-goer, too. "Well, my lord, I dunno," says I. "Tientsin ain't much of a place, but I'll see what I can drum up - "
"Michel's been reading Doctor Thorne since Taku," cried he. "He must have finished it by now, surely! Ask him, Flashman, will you?" So I did, and had my ignorance, enlightened. — George MacDonald Fraser

Whoever is led to believe that species are mutable will do good service by conscientiously expressing his conviction; for only thus can the load of prejudice by which this subject is overwhelmed be removed. — Charles Darwin

What surprises me most when surveying the great destinies of man is always seeing before me the opposite of what Darwin and his school see or want to see today: selection in favor of the stronger, in favor of those who have come off better, the progress of the species. The very opposite is quite palpably the case: the elimination of the strokes of luck, the uselessness of the better-constituted types, the inevitable domination achieved by the average, even below-average types. — Friedrich Nietzsche

If Darwin had seen in life what Dostoevsky saw, he would not have talked of the law of the preservation of species, but of its destruction. — Lev Shestov

Who can explain why one species ranges widely and is very numerous, and why another allied species has a narrow range and is rare? Yet these relations are of the highest importance, for they determine the present welfare, and, as I believe, the future success and modification of every inhabitant of this world. — Charles Darwin

Why is The Origin of Species such a great book? First of all, because it convincingly demonstrates the fact of evolution: it provides a vast and well-chosen body of evidence showing that existing animals and plants cannot have been separately created in their present forms, but must have evolved from earlier forms by slow transformation. And secondly, because the theory of natural selection, which the Origin so fully and so lucidly expounds, provides a mechanism by which such transformation could and would automatically be produced. — Charles Darwin

CONTRARY TO THE COMMON ASSUMPTION , Charles Darwin did not originate the idea of evolution. By the middle of the nineteenth century, the mere fact of evolution had been around for a long time, and most thinkers of the time were perfectly content to leave it at that. The absence of a theory to explain evolutionary change didn't trouble them, wasn't experienced as a pressure, as it was by Darwin. He knew there had to be some intelligible mechanism or dynamic that would account for it, and this is what he went looking for - with well-known results. In his Origin of Species, he wasn't announcing the fact of evolution, he was trying to make sense of that fact. — Daniel Quinn

Sir Julian Huxley, one of the world's leading evolutionists, head of UNESCO, descendant of Thomas Huxley - Darwin's bulldog - said on a talk show, 'I suppose the reason we leaped at The Origin of Species was because the idea of God interfered with our sexual mores.'. — Julian Huxley

I read five books on the Constitution. My favorite was 'Plain, Honest Men' by Richard Beeman. I went on a science jag in the same way. I kept getting in arguments about evolution and being bested. So I read Charles Darwin's 'On the Origin of the Species,' a fantastic book that is not that difficult. — Denis O'Hare

So the horns of the stag are sharp to offend his adversary, but are branched for the purpose of parrying or receiving the thrusts of horns similar to his own, and have therefore been formed for the purpose of combating other stags for the exclusive possession of the females; who are observed, like the ladies in the times of chivalry, to attend to the car of the victor. The final cause of this contest amongst the males seems to be, that the strongest and most active animal should propagate the species, which should thence become improved. — Erasmus Darwin

Mr. Darwin refers to the multitude of the individual of every species, which, from one cause or another, perish either before, or soon after attaining maturity. — Richard Owen

The several difficulties here discussed, namely our not finding in the successive formations infinitely numerous transitional links between the many species which now exist or have existed; the sudden manner in which whole groups of species appear in our European formations; the almost entire absence, as at present known, of fossiliferous formations beneath the Silurian strata, are all undoubtedly of the gravest nature. — Charles Darwin

Nevertheless so profound is our ignorance, and so high our presumption, that we marvel when we hear of the extinction of an organic being; and as we do not see the cause, we invoke cataclysms to desolate the world, or invent laws on the duration of the forms of life! — Charles Darwin

Sexual selection will also be largely dominated by natural selection tending towards the general welfare of the species. — Charles Darwin

As Darwin noted, "It is certain that with almost all animals there is a struggle between the males for the possession of the female." When males of a species battle it out directly, be it through the clashing antlers of deer, the stabbing horns of the stag beetle, the head butting of stalk-eyed flies, or the bloody battles of massive elephant seals, they win access to females by driving off competitors. Selection will favor any trait that promotes such victories so long as the increased chance of getting mates more than offsets any reduced survival. This kind of selection produces armaments: stronger weapons, larger body size, or anything that helps a male win physical contests. — Jerry A. Coyne

When the views entertained in this volume on the origin of species, or when analogous views are generally admitted, we can dimly forsee that there will be a considerable revolution in natural history. — Charles Darwin

It's a flaw in our argument, for sure. By any reading of evolutionary theory, creationists ought to have died out ages ago. They serve no function in the planet's ecosystem, and no other species has survived so long while in such fundamental disagreement with observable reality. If I wasn't such an ardent believer in secular materialism, I'd wager this is really troubling Darwin in the afterlife. — Richard Dawkins

The publication in 1859 of the Origin of Species by Charles Darwin made a marked epoch in my own mental development, as it did in that of human thought generally.
