I see the triumph of good over evil as a manifestation of the error-correcting process of evolution. ~ Jonas Salk

Evolution means a process of change or transformation, and is commonly used to refer to biological, genetic or organic evolution, the changes in populations of organisms over generations, the processes by which such changes occur, and theories regarding them. Offspring differ from their parents in various ways.

  • The world has arisen in some way or another. How it originated is the great question, and Darwin's theory, like all other attempts to explain the origin of life, is thus far merely conjectural. I believe he has not even made the best conjecture possible in the present state of our knowledge.

  • Molecular evolution is not based on scientific authority. . . . There are assertions that such evolution occurred, but absolutely none are supported by pertinent experiments or calculations. Since no one knows molecular evolution by direct experience, and since there is no authority on which to base claims of knowledge, it can truly be said that . . . the assertion of Darwinian molecular evolution is merely bluster.

  • [While research] … has revealed unexpected, stunning complexity, no progress at all has been made in understanding how that complexity could evolve by unintelligent processes.
  • Currently, I see in Germany, but also in the United States, a somewhat fierce debate raging between so-called "creationism" and evolutionism, presented as though they were mutually exclusive alternatives: those who believe in the Creator would not be able to conceive of evolution, and those who instead support evolution would have to exclude God. This antithesis is absurd because, on the one hand, there are so many scientific proofs in favour of evolution which appears to be a reality we can see and which enriches our knowledge of life and being as such. But on the other, the doctrine of evolution does not answer every query, especially the great philosophical question: where does everything come from? And how did everything start which ultimately led to man?
  • Darwin's theory of evolution is the last of the great 19th century mystery religions. And as we speak it is now following Freudianism and Marxism into the nether regions, and I'm quite sure that Freud, Marx, and Darwin are commiserating one with the other, in the dark dungeon where discarded gods gather.

  • The evolutionary vision is agnostic in regard to systems in the universe of greater complexity than those of which human beings have clear knowledge. It recognizes aesthetic, moral, and religious ideas and experiences as a species, in this case of mental structures or of images, which clearly interacts with other species in the world's great ecosystem.
  • The rise of every man he loved to trace,
    Up to the very pod O!
    And, in baboons, our parent race
    Was found by old Monboddo.

    And learn their qui, quæ, quod, O!
    Till Hebrew, Latin, Welsh, and Greek
    They knew as well's Monboddo!

  • The power of custom is enormous, and so gradual will be the change, that man's sense of what is due to himself will be at no time rudely shocked; our bondage will steal upon us noiselessly and by imperceptible approaches; nor will there ever be such a clashing of desires between man and the machines as will lead to an encounter between them. Among themselves the machines will war eternally, but they will still require man as the being through whose agency the struggle will be principally conducted. In point of fact there is no occasion for anxiety about the future happiness of man so long as he continues to be in any way profitable to the machines; he may become the inferior race, but he will be infinitely better off than he is now. Is it not then both absurd and unreasonable to be envious of our benefactors? And should we not be guilty of consummate folly if we were to reject advantages which we cannot obtain otherwise, merely because they involve a greater gain to others than to ourselves?
With those who can argue in this way I have nothing in common. I shrink with as much horror from believing that my race can ever be superseded or surpassed, as I should do from believing that even at the remotest period my ancestors were other than human beings. Could I believe that ten hundred thousand years ago a single one of my ancestors was another kind of being to myself, I should lose all self-respect, and take no further pleasure or interest in life. I have the same feeling with regard to my descendants, and believe it to be one that will be felt so generally that the country will resolve upon putting an immediate stop to all further mechanical progress, and upon destroying all improvements that have been made for the last three hundred years. I would not urge more than this. We may trust ourselves to deal with those that remain, and though I should prefer to have seen the destruction include another two hundred years, I am aware of the necessity for compromising, and would so far sacrifice my own individual convictions as to be content with three hundred. Less than this will be insufficient.”

  • The first objection to Darwinism is that it is only a guess and was never anything more. It is called a “hypothesis,” but the word “hypothesis,” though euphonious, dignified and high-sounding, is merely a scientific synonym for the old-fashioned word “guess.” If Darwin had advanced his views as a guess they would not have survived for a year, but they have floated for half a century, buoyed up by the inflated word “hypothesis.” When it is understood that “hypothesis” means “guess,” people will inspect it more carefully before accepting it.

  • The only part of evolution in which any considerable interest is felt is evolution applied to man. A hypothesis in regard to the rocks and plant life does not affect the philosophy upon which one's life is built. Evolution applied to fish, birds and beasts would not materially affect man's view of his own responsibilities except as the acceptance of an unsupported hypothesis as to these would be used to support a similar hypothesis as to man. The evolution that is harmful—distinctly so—is the evolution that destroys man’s family tree as taught by the Bible and makes him a descendant of the lower forms of life. This … is a very vital matter.

  • Why, these men would destroy the Bible on evidence that would not convict a habitual criminal of a misdemeanor. They found a tooth in a sand pit in Nebraska with no other bones about it, and from that one tooth decided that it was the remains of the missing link. They have queer ideas about age too. They find a fossil and when they are asked how old it is they say they can't tell without knowing what rock it was in, and when they are asked how old the rock is they say they can't tell unless they know how old the fossil is.
    • William Jennings Bryan In Henry Fairfield Osborn, 'Osborn States the Case For Evolution', New York Times (12 Jul 1925), XX1. In fact, the tooth was misidentified as anthropoid by Osborn, who over-zealously proposed Nebraska Man in 1922. This tooth was shortly thereafter found to be that of a peccary (a Pliocene pig) when further bones were found. A retraction was made in 1927, correcting the scientific blunder.
  • The real question is, Did God use evolution as His plan? If it could be shown that man, instead of being made in the image of God, is a development of beasts we would have to accept it, regardless of its effort, for truth is truth and must prevail. But when there is no proof we have a right to consider the effect of the acceptance of an unsupported hypothesis.

  • A hen is only an egg's way of making another egg.


  • There are many examples in evolution of a vital adaptation taking place at a cost. Anatomically, evolution seems to create a series of compromises; advantages tempered by being achieved against the constraints of the existing raw material. Upright walking has the cost of disorders in the back and acute difficulties in childbirth. Speech has the cost of a structure of the larynx which is extremely dangerous. The fact of these compromises does of course emphasize the power of the need that the advantage be achieved. If it is dangerous to speak, the pressure in its favor must have been very strong.
  • Perhaps the most important single contribution that the study of human evolution can make, especially to the non-scientific community, is to set these racial differences in their historical context. People may still feel hostile towards one another for all kinds of irrational reasons. But the study of evolution can demonstrate just how misplaced some of those reasons are.

  • Authors of the highest eminence seem to be fully satisfied with the view that each species has been independently created. To my mind it accords better with what we know of the laws impressed on matter by the Creator, that the production and extinction of the past and present inhabitants of the world should have been due to secondary causes, like those determining the birth and death of the individual. When I view all beings not as special creations, but as the lineal descendants of some few beings which lived long before the first bed of the Silurian system was deposited, they seem to me to become ennobled.
  • I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.
  • The expression often used by Mr. Herbert Spencer of the Survival of the Fittest is more accurate, and is sometimes equally convenient.
  • Mere chance … alone would never account for so habitual and large an amount of difference as that between varieties of the same species and species of the same genus.
  • This belief, that Darwinian evolution is "random", is not merely false. It is the exact opposite of the truth. Chance is a minor ingredient in the Darwinian recipe, but the most important ingredient is cumulative selection which is quintessentially non-random.
  • Natural selection, the blind, unconscious, automatic process which Darwin discovered … has no purpose in mind. … It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of watchmaker in nature, it is the blind watchmaker.
  • In any developing science there are disagreements. But scientists — and here is what separates real scientists from the pseudoscientists of the school of intelligent design — always know what evidence it would take to change their minds. One thing all real scientists agree upon is the fact of evolution itself. It is a fact that we are cousins of gorillas, kangaroos, starfish, and bacteria. Evolution is as much a fact as the heat of the sun. It is not a theory, and for pity’s sake, let’s stop confusing the philosophically naive by calling it so. Evolution is a fact.
  • Nature is neither kind nor unkind. She is neither against suffering nor for it. Nature is not interested in suffering one way or the other unless it affects the survival of DNA. It is easy to imagine a gene that, say, tranquilizes gazelles when they are about to suffer a killing bite. Would such a gene be favored by natural selection?
Not unless the act of tranquilizing a gazelle improved that gene's chances of being propagated into future generations. It is hard to see why this should be so, and we may therefore guess that gazelles suffer horrible pain and fear when they are pursued to the death - as many of them eventually are. The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are being slowly devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst and disease.
  • There can be no question that Darwin had nothing like sufficient evidence to establish his theory of evolution. … Darwin’s model of evolution … , being basically a theory of historical reconstruction, … is impossible to verify by experiment or direct observation as is normal in science … Moreover, the theory of evolution deals with a series of unique events, the origin of life, the origin of intelligence and so on. Unique events are unrepeatable and cannot be subjected to any sort of experimental investigation. … His general theory, that all life on earth had originated and evolved by a gradual successive accumulation of fortuitous mutations, is still, as it was in Darwin’s time, a highly speculative hypothesis entirely without direct factual support and very far from that self-evident axiom some of its more aggressive advocates would have us believe. … The evolutionary paradigm … is more like a principle of medieval astrology than a serious twentieth century scientific theory. … One might have expected that a theory of such cardinal importance, a theory that literally changed the world, would have been something more than metaphysics, something more than a myth.

    • (If it were true that "a theory of historical reconstruction … is impossible to verify", then this truth would invalidate not only evolution, but also all of forensic science.)
    • (It took Darwin twenty-one years (from 1838 to 1859) to develop the core of the theory of evolution, and the theory keeps developing even to the present day. No one considers it "self-evident".)
  • What is the question now placed before society with the glib assurance which to me is most astonishing? That question is this: Is man an ape or an angel? I, my lord, I am on the side of the angels. I repudiate with indignation and abhorrence those new fangled theories.
  • According to Goldschmidt, all that evolution by the usual mutations—dubbed "micromutations"—can accomplish is to bring about "diversification strictly within species, usually, if not exclusively, for the sake of adaptation of the species to specific conditions within the area which it is able to occupy." New species, genera, and higher groups arise at once, by cataclysmic saltations—termed macromutations or systematic mutations—which bring about in one step a basic reconstruction of the whole organism. The role of natural selection in this process becomes "reduced to the simple alternative: immediate acceptance or rejection." A new form of life having been thus catapulted into being, the details of its structures and functions are subsequently adjusted by micromutation and selection. It is unnecessary to stress here that this theory virtually rejects evolution as this term is usually understood (to evolve means to unfold or to develop gradually), and that the systematic mutations it postulates have never been observed. It is possible to imagine a mutation so drastic that its product becomes a monster hurling itself beyond the confines of species, genus, family, or class. But in what Goldschmidt has called the "hopeful monster" the harmonious system, which any organism must necessarily possess, must be transformed at once into a radically different, but still sufficiently coherent, system to enable the monster to survive. The assumption that such a prodigy may, however rarely, walk the earth overtaxes one's credulity, even though it may be right that the existence of life in the cosmos is in itself an extremely improbable event.
  • The secular picture … proposes a purely physical and purposeless universe, inhabited by evolutionary accidents whose sense of self is probably illusory.


  • Paleontologists should recognize that much of their thought is conditioned by a peculiar perspective that they must bring to the study of life: they must look down from its present complexity and diversity into the past: their view must be retrospective. From this vantage point, it is very difficult to view evolution as anything but an easy and inevitable result of mere existence, as something that unfolds in a natural and orderly fashion. Yet we urge a different view. The norm for a species or, by extension, a community is stability. Speciation is a rare and difficult event that punctuates a system in homeostatic equilibrium. That so uncommon an event should have produced such a wondrous array of living and fossil forms can only give strength to an old idea: paleontology deals with a phenomenon that belongs to it alone among the evolutionary sciences and that enlightens all its conclusions—time.


  • When we read in Genesis the account of Creation, we risk imagining that God was a magician, with such a magic wand as to be able to do everything. However, it was not like that. He created beings and left them to develop according to the internal laws that He gave each one, so that they would develop, and reach their fullness. He gave autonomy to the beings of the universe at the same time that He assured them of his continual presence, giving being to every reality. And thus creation went forward for centuries and centuries, millennia and millennia until it became what we know today, in fact because God is not a demiurge or a magician, but the Creator who gives being to all entities. The beginning of the world was not the work of chaos, which owes its origin to another, but it derives directly from a Supreme Principle who creates out of love. The Big-Bang, that is placed today at the origin of the world, does not contradict the divine intervention but exacts it. The evolution in nature is not opposed to the notion of Creation, because evolution presupposes the creation of beings that evolve.

  • God is an unnecessary hypothesis for explaining the natural world. But … this is not something that needs to be ascribed to God anyway, so it hardly implies that evolution and religion are incompatible, any more than showing that God is not needed to explain plumbing makes plumbing incompatible with religion.

  • I do not want to discuss evolution in such depth, however, only touch on it from my own perspective: from the moment when I stood on the Serengeti plains holding the fossilized bones of ancient creatures in my hands to the moment when, staring into the eyes of a chimpanzee, I saw a thinking, reasoning personality looking back. You may not believe in evolution, and that is all right. How we humans came to be the way we are is far less important than how we should act now to get out of the mess we have made for ourselves.
    • Jane Goodall Reason for Hope: a Spiritual Journey (2000), with Phillip Berman P. xx.
  • Imagine that we didn't know the chimpanzee, that all we knew were those bonobos who have sex all the time and are peaceful and female-dominated and that people would say that this is our only close relative. I think we would have totally different theories about ourselves and our background. But, of course, it didn't happen that way.
  • I think if we study the primates, we notice that a lot of these things that we value in ourselves, such as human morality, have a connection with primate behavior. This completely changes the perspective, if you start thinking that actually we tap into our biological resources to become moral beings. That gives a completely different view of ourselves than this nasty selfish-gene type view that has been promoted for the last 25 years.
  • We applaud the burgeoning emphasis on change in regulatory genes as the stuff of morphological evolution... if only because one of us had written a book to argue that the classical, and widely ignored data on evolution by heterochrony should be exhumed and valued as a primary demonstration of regulatory change. We do not see how point mutations in structural genes can lead, even by gradual accumulations, to new morphological designs. Regulatory changes in the timing of complex ontogenetic programs seem far more promising—and potentially rapid, in conformity with our punctuational predilections. The near identity of humans and chimps for structural genes, and the evidence of major regulatory change indicated by human neoteny provides an important confirmation.
  • Los pasivos alzan el clamor llamándose apóstoles de la evolución y condenando todo lo que tiene algo de rebeldía; apelan al miedo, hacen llamamientos patéticos al patriotismo; acuden a la ignorancia y llegan a aconsejar al pueblo que se deje matar y ultrajar en los próximos comicios y vuelvan una y otra vez a ejercer pacíficamente el derecho de sufragio, a que una y otra vez lo burlen y lo asesinen los tiranos. Pero nada de salirse del fétido rincón, al cual se pretende evolucionar agregando más y más inmundicias, más y más cobardías. ... La evolución verdadera que mejore la vida de los mexicanos, no la de sus parásitos, vendrá con la revolución: ésta y aquella se completan y la primera no pueda coexistir con los anacronisnos y subterfugios que despiertan hoy los redentores del pasivismo. Para evolucionar es preciso ser libre y no podemos tener libertad si no somos rebeldes, porque nunca tirano alguno ha respetado a los pueblos pasivos; jamás un rebaño de carneros se ha impuesto con la majestad de su número inofensivo, al lobo que bonitamente los devora sin cuidarse de otro derecho que el de sus dientes. Hay que armarse, pero no de un voto inútil, que siempre valdrá tanto como el tirano quiere, sino de armas efectivas y menos candorosas cuyo uso nos traiga la evolución ascendente y no la regresiva que preconizan los luchadores pacifistas. ¡Pasividad, nunca! Rebeldía, ahora y siempre.
    • The quiescent ones raise an outcry calling themselves apostles of evolution, condemning everything that has any hint of rebelliousness; they appeal to fear and make pathetic patriotic calls; they resort to ignorance and go so far as to advise the people to let themselves be murdered and insulted during the next round of elections, to again and again peacefully exercise their right to vote, so that the tyrants mock them and assassinate them over and over. No mention of leaving the fetid corner, which they propose to improve by adding more and more filth, more and more cowardice. ... True evolution that will improve of the lives of Mexicans, rather than their parasites, will come with the Revolution. The two complement each other, and the former cannot coexist with the anachronisms and subterfuges that the redeemers of passivity employ today. To evolve we must be free, and we cannot have freedom if we are not rebels, because no tyrant whatsoever has respected passive people. Never has a flock of sheep instilled the majesty of its harmless number upon the wolf that craftily devours them, caring for no right other than that of his teeth. We must arm ourselves, not using the useless vote that will always be worth only as much as a tyrant wants, but rather with effective and less naive weapons whose utilization will bring us ascendant evolution instead of the regressive one praised by pacifist activists. Passivity, never! Rebellion—now and always.

  • The old "red in tooth and claw" view of the natural economy has to be updated. We need a new metaphor for the forest, one that helps us visualize plants both sharing and competing. … Evolution's engine is fired by genetic self-interest, but this manifests itself in cooperative action as well as solo selfishness. The natural economy has as many trade unions as robber barons, as much solidarity as individualistic entrepreneurship.

  • Darwinian evolution is most unlikely to get even one polypeptide [chain of essential life substances] right, let alone the thousands on which living cells depend for survival. This situation is well known to geneticists and yet nobody seems to blow the whistle decisively on the theory.
  • But were this world ever so perfect a production, it must still remain uncertain, whether all the excellencies of the work can justly be ascribed to the workman. If we survey a ship, what an exalted idea must we form of the ingenuity of the carpenter who framed so complicated, useful, and beautiful a machine? And what surprise must we feel, when we find him a stupid mechanic, who imitated others, and copied an art, which, through a long succession of ages, after multiplied trials, mistakes, corrections, deliberations, and controversies, had been gradually improving? Many worlds might have been botched and bungled, throughout an eternity, ere this system was struck out; much labour lost; many fruitless trials made; and a slow, but continued improvement carried on during infinite ages in the art of world-making. In such subjects, who can determine, where the truth; nay, who can conjecture where the probability, lies; amidst a great number of hypotheses which may be proposed, and a still greater number which may be imagined?
  • So far from a gradual progress towards perfection forming any necessary part of the Darwinian creed, it appears to us that it is perfectly consistent with indefinite persistence in one state, or with a gradual retrogression.
  • We have always thought that Mr. Darwin has unnecessarily hampered himself by adhering so strictly to his favourite "Natura non facit saltum." We greatly suspect that she does make considerable jumps in the way of variation now and then, and that these saltations give rise to some of the gaps which appear to exist in the series of known forms.
  • The antagonism between science and religion, about which we hear so much, appears to me to be purely factitious — fabricated, on the one hand, by short-sighted religious people who confound a certain branch of science, theology, with religion; and, on the other, by equally short-sighted scientific people who forget that science takes for its province only that which is susceptible of clear intellectual comprehension; and that, outside the boundaries of that province, they must be content with imagination, with hope, and with ignorance.

  • The important point is that all the standard attributes assigned to God in our history could equally well be the characteristics of biological entities who billions of years ago were at a stage of development similar to man's own and evolved into something as remote from man as man is remote from the primordial ooze from which he first emerged.


  • Why don't we see gradual transition in the sequences of fossils? According to Darwin, and the current neo-Darwinists, the fossil record has gaps in it because of the haphazard way in which fossilization occurs — it is bound to be an imperfect record of the history of life. But is it? Is the jerky and abrupt nature of the record really just due to 'gaps', or does it reflect the way evolution actually happened? There is a strong feeling among leading palaeontologists that the punctuated history shown by fossils reflects the way life has evolved — in leaps and bounds rather than in gradual transition. There is also a growing sense that there is much more to understanding 'macroevolution' — the large-scale picture one gets from the fossils — than the simple idea of natural selection can alone explain.

  • Ever since language allowed human cultural evolution to impinge upon age-old processes of biological evolution, humankind has been in a position to upset older balances of nature in quite the same fashion as disease upsets the natural balance within a host's body. Time and again, a temporary approach to stabilization of new relationships occurred as natural limits to the ravages of humankind upon other life forms manifested themselves. Yet, sooner or later, and always within a span of time that remained miniscule in comparison with the standards of biological evolution, humanity discovered new techniques allowing fresh exploitation of hitherto inaccessible forms of life.
  • Evolution isn't just a story about where we came from. It's an epic at the center of life itself. Far from robbing our lives of meaning, it instills an appreciation for the beautiful, enduring, and ultimately triumphant fabric of life that covers our planet. Understanding that doesn't demean human life - it enhances it.
  • Another curious aspect of the theory of evolution is that everybody thinks he understands it. I mean philosophers, social scientists, and so on. While in fact very few people understand it, actually, as it stands, even as it stood when Darwin expressed it, and even less as we now may be able to understand it in biology.

  • Man, in that sense, will never die, because there may never be a taxonomical point in his evolutionary progress that can be determined as the last stage of man in the cline turning him into Neohomo, or some horrible throbbing slime.
  • We do not have to adapt to the environment. We will change the environment to suit us.
  • Pouter, tumbler, and fantail are from the same source;
    The racer and hack may be traced to one Horse;
    So men were developed from monkeys of course,
    Which nobody can deny.
    • Charles Neaves, The Origin of Species; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.
  • Most of us make one of two basic assumptions: we view the universe as a result of random events and life on this planet a matter of chance; or we assume an Intelligence beyond the universe who gives the universe order, and life meaning.


  • We conclude — unexpectedly — that there is little evidence for the neo-Darwinian view: its theoretical foundations and the experimental evidence supporting it are weak, and there is no doubt that mutations of large effect are sometimes important in adaptation. We hasten to add, however, that we are not "macromutationists" who believe that adaptations are nearly always based on major genes. The neo-Darwinian view could well be correct. … We hope to encourage evolutionists to reexamine this neglected question and to provide evidence to settle it.

    • (The first sentence is sometimes quoted in isolation by creationists to suggest incorrectly that "there is little evidence" for evolution. In fact, the "neo-Darwinian view" under question is the relative importance of many small changes versus a few large changes.)


  • Development of an organism from a single germ cell into a multicellular entity is a self-organizing system from any point of view and I wish to contend that this self-organizing system is a subsystem of the self-organizing system called 'evolution'.
    • Gordon Pask An Approach to Cybernetics (1961) p. 103-104
  • New knowledge has led to the recognition of the theory of evolution as more than a hypothesis. It is indeed remarkable that this theory has been progressively accepted by researchers, following a series of discoveries in various fields of knowledge. The convergence, neither sought nor fabricated, of the results of work that was conducted independently is in itself a significant argument in favor of this theory.
  • Gould discusses iconographies like the “great chain of being” 1 and the “march of progress” as influencing our perceptions of evolution. Today “family tree”-style pictures are beginning to replace the traditional image of the “march of progress” in biology textbooks. However, outside academia, there are still countless visual representations of evolution that maintain the fiction that evolution inevitably follows a certain predetermined linear progression and that that trajectory moves towards humanoid bodies and human or superhuman brains. Science fiction movies, TV shows, and comic books are powerful iconographies in today’s society, continuing to perpetuate the myth of trajectory-based evolution. According to the sci-fi genre, evolution follows an internal “blueprint,” a preset trajectory that takes organisms from simplicity to complexity for complexity’s sake.
  • Even in her transfigured state, the thought of goal-oriented evolution gave Evelyn the creeps. It smacked of Intelligent Design, the ludicrous evangelism of engineers masquerading as biologists, their PowerPoint presentations riddled with evasions and half-truths and pseudoscience. Such thinking confused causes and effects; it complicated unnecessarily the idea of evolution, a field where explanations are valuable only for their parsimony.
  • The Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter.



  • An organism’s adaptations to its environment, such as the dandelion seed’s parachute, are the result of evolution. Evolution is the process of change that has transformed life on Earth from its earliest beginnings to the diversity of organisms living today. Because evolution is the fundamental organizing principle of biology, it is the core theme of this book.

  • There is consensus among biologists that evolution is the core theme of biology. The evolutionary changes seen in the fossil record are observable facts. Furthermore, as we’ll describe, evolutionary mechanisms account for the unity and diversity of all species on Earth.

  • Most educated people are aware that we're the outcome of nearly 4 billion years of Darwinian selection, but many tend to think that humans are somehow the culmination. Our sun, however, is less than halfway through its lifespan. It will not be humans who watch the sun's demise, 6 billion years from now. Any creatures that then exist will be as different from us as we are from bacteria or amoebae.

  • Look, you pinheads who attack me for this, you guys are just desperate. … How did that little amoeba get here, crawl out there? How'd it do it? Come on. … Okay, if we have existence, if we have life on earth, how come they don't have it on the other planets? Were we just lucky? Some meteor do this? Boom. Come on. You know, I see this stuff, it's desperate. As I've said many times, it takes more faith to not believe and to think that this was all luck - all this human body - the intricacies of it and everything else, all luck --- than it does to believe in a deity. There yah go.
  • Germs and disease vectors are moving targets, and evolution is the reason for this. Evolution happens in hospitals... over the course of just a few months. What you don't know about evolution can kill you.

  • The fact is that your plane originated because enough entities needed certain types of experience to warrant such a creation, and they set about forming it through the process of evolution.

  • Equidem æterna constitutione crediderim nexuque causarum latentium et multo ante destinatarum suum quemque ordinem immutabili lege percurrere.
    • For my own part I am persuaded that everything advances by an unchangeable law through the eternal constitution and association of latent causes, which have been long before predestinated.

  • Owing to the identification of religion with virtue, together with the fact that the most religious men are not the most intelligent, a religious education gives courage to the stupid to resist the authority of educated men, as has happened, for example, where the teaching of evolution has been made illegal. So far as I can remember, there is not one word in the Gospels in praise of intelligence; and in this respect ministers of religion follow gospel authority more closely than in some others.


  • When things get bad enough, then something happens to correct the course. And it is for that reason that I speak of evolution as an error-making and error-correcting process. And if we can be ever so much better — ever so much slightly better — at error correcting than at error making, then we'll make it.
  • Things evolve to evolve. Evolutionary processes are the linchpin of change. These processes of discovery represent a complexity of simple systems that flux in perpetual tension as they teeter at the edge of chaos. This whirlwind of emergence is responsible for the spontaneous order and higher, organized complexity so noticeable in biological evolution—one–celled critters beefing up to become multicellular organisms.

  • The hallmark of evolution is its ability to process situations and generate order without relying on the crutch of a conscious designer. Most complex systems grow organically, solutions evolving through unguided and mindless forces, never reaching any final state.

  • I judge things from an evolutionary perspective — "How does this serve and contribute to the process of our own evolution?" — rather than think of good and evil in moral terms. I see the triumph of good over evil as a manifestation of the error-correcting process of evolution.
    • Jonas Salk, in Academy of Achievement interview, in San Diego, California (16 May 1991)
  • I speak about universal evolution and teleological evolution, because I think the process of evolution reflects the wisdom of nature. I see the need for wisdom to become operative. We need to try to put all of these things together in what I call an evolutionary philosophy of our time.
    • Jonas Salk, in Academy of Achievement interview, in San Diego, California (16 May 1991)
  • I do not believe in evolution … and none of your professors believe in evolution. … Beliefs are opinions.

  • If I did not think you a good tempered & truth loving man I should not tell you that... I have read your book [On the Origin of Species] with more pain than pleasure. Parts of it I admired greatly; parts I laughed at till my sides were almost sore; other parts I read with absolute sorrow; because I think them utterly false & grievously mischievous— You have deserted—after a start in that tram-road of all solid physical truth—the the true method of induction. … I have written in a hurry & in a spirit of brotherly love.

  • You grow, we all grow, we're made to grow. You either evolve or disappear.
  • This argument [that life is too improbable to have arisen by chance] comes up repeatedly: its latest manifestation is Hoyle's discussion of the likelihood of a wind blowing through a junkyard assembling a Boeing 707 [sic]. What is wrong with it? Essentially, it is that no biologist imagines that complex structures arise in a single step.
  • Thus life by life and love by love
    We passed through the cycles strange,
    And breath by breath and death by death
    We followed the chain of change.
  • When you were a tadpole and I was a fish, in the Palæozoic time

  • Organic evolution has its physical analogue in the universal law that the world tends, in all its parts and particles, to pass from certain less probable to certain more probable configurations or states. This is the second law of thermodynamics. It has been called the law of evolution of the world; and we call it, after Clausius, the Principle of Entropy, which is a literal translation of Evolution in Greek.
  • Aristotle especially, both by speculation and observation... reached something like the modern idea of a succession of higher organizations from lower, and made the fruitful suggestion of "a perfecting principle" in Nature. With the coming in of Christian theology this tendency toward a yet truer theory of evolution was mainly stopped, but the old crude view remained...
  • Just as the line of astronomical thinkers from Copernicus to Newton had destroyed the old astronomy, in which the earth was the center, and the Almighty sitting above the firmament the agent in moving the heavenly bodies about it with his own hands, so now a race of biological thinkers had destroyed the old idea of a Creator minutely contriving and fashioning all animals to suit the needs and purposes of man.
  • Of course, like every other man of intelligence and education I do believe in organic evolution. It surprises me that at this late date such questions should be raised.
  • And hear the mighty stream of tendency
    Uttering, for elevation of our thought,
    A clear sonorous voice, inaudible
    To the vast multitude.
