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.

  • 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 euphonioous, 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.

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.

  • Anthropological, biological, and genetic evidence all put the origin of modern humans at between 200,000 and 100,000 years ago, probably in Africa. There is also much data that show an outburst of cultural behavior occurring around 50,000-40,000 years ago in Europe. That's when archaeologists date the oldest evidence of burial ceremonies, body ornaments, and cave paintings.

  • 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.
  • The secular picture … proposes a purely physical and purposeless universe, inhabited by evolutionary accidents whose sense of self is probably illusory.




  • 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.


  • 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.

  • These odds [50,000,000,000,000,000,000 to 1] are roughly the same as you could give to the idea of just one of our body's proteins having evolved randomly, by chance. … A junkyard contains all the bits and pieces of a Boeing 747, dismembered and in disarray.

    • Fred Hoyle, The Intelligent Universe, 1983, p. 12-19
  • 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?
  • 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.

    • Ben King, Evolution; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.


  • 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.
  • 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.

  • 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.

  • I think human consciousness, is a tragic misstep in evolution. We became too self-aware, nature created an aspect of nature separate from itself, we are creatures that should not exist by natural law. We are things that labor under the illusion of having a self; an accretion of sensory, experience and feeling, programmed with total assurance that we are each somebody, when in fact everybody is nobody. Maybe the honorable thing for our species to do is deny our programming, stop reproducing, walk hand in hand into extinction, one last midnight - brothers and sisters opting out of a raw deal.
  • 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.
  • 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.
  • 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?
  • 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.

  • 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.

    • 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.
    • Eugenie C. Scott, "The Evolution of Creationism," address at Oberlin College, Oberlin, Ohio (1 May 2007)
    • [Reported by Caitlin Duke, "Evolution and Creationism," The Oberlin Review (4 May 2007) volume 135, number 23, page 2.]
  • 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.
    • Adam Sedgwick, letter to Darwin (24 November 1859); reprinted in The Correspondence of Charles Darwin volume 7, p. 396
  • 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
    And side by side in the sluggish tide, we sprawled in the ooze and slime.
    • Langdon Smith, A Toast to a Lady (Evolution); printed in The Scrap Book (April, 1906); Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.
  • Civilization is a progress from an indefinite, incoherent homogeneity toward a definite, coherent heterogeneity.
    • Herbert Spencer, First Principles, Chapter XVI. Par. 138; also Chapter XVII. Par. 145. He summaries the same: From a relatively diffused, uniform, and indeterminate arrangement to a relatively concentrated, multiform, and determinate arrangement; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.
  • This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called "natural selection, or the preservation of favoured races in the struggle for life."
    • Herbert Spencer, Principles of Biology, Indirect Equilibration; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.
  • Evolution is a change from an indefinite, incoherent, homogeneity to a definite, coherent, heterogeneity, through continuous differentiations and integrations.
    • Herbert Spencer, First Principles (1862)
    • Evolution is a change from a no-howish untalkaboutable all-alikeness by continous sticktogetheration and somethingelsification.
      • A parody of the above quote, often attributed to William James, 1880 (Lecture Notes 1880-1897), but see [2]


  • Out of the dusk a shadow,
    Then a spark;
    Out of the cloud a silence,
    Then a lark;
    Out of the heart a rapture,
    Then a pain;
    Out of the dead, cold ashes,
    Life again.
    • John Banister Tabb, Evolution; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.
  • Solana, the Ood aren't born like this. They can't be. A species born to serve could never evolve in the first place. What does the company do to make them obey?
  • You idiot. They're born with their brains in their hands. Don't you see, that makes them peaceful. They've got to be, because a creature like that would have to trust anyone it meets.
  • The Lord let the house of a brute to the soul of a man,
    And the man said, "Am I your debtor?"
    And the Lord—"Not yet: but make it as clean as you can,
    And then I will let you a better."
    • Alfred Tennyson, By an Evolutionist; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.
  • Is there evil but on earth? Or pain in every peopled sphere?
    Well, be grateful for the sounding watchword "Evolution" here.
    • Alfred Tennyson, Locksley Hall Sixty Years After (1886), line 198; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.
  • Evolution ever climbing after some ideal good
    And Reversion ever dragging Evolution in the mud.
    • Alfred Tennyson, Locksley Hall Sixty Years After (1886), line 200; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.
  • When I was a shepherd on the plains of Assyria.
    • Henry David Thoreau; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 241-42.


  • 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.
