Selection Theory Quotes & Sayings

In 2010, my two Harvard mathematician colleagues and I dismantled kin-selection theory, which was the reigning theory of the origin of altruism at the time. — E. O. Wilson

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

For reasons that are both obvious and highly functional, science textbooks (and too many of the older histories of science) refer only to that part of the work of past scientists that can easily be viewed as contributions to the statement and solution of the texts' paradigm problems. Partly by selection and partly by distortion, the scientists of early ages are implicitly represented as having worked upon the same set of fixed problems and in accordance with the same set of fixed canons that the most recent revolution in scientific theory and method has made seem scientific. — Thomas S. Kuhn

Of course, there is no reconciliation between the theory of evolution by natural selection and the traditional religious view of the origin of the human mind. — E. O. Wilson

One thing that makes the adventure of working in our field particularly rewarding, especially in attempting to improve the theory, is that ... a chief criterion for the selection of a correct hypothesis ... seems to be the criterion of beauty, simplicity, or elegance. — Murray Gell-Mann

The bradys must hold that, on the average, cumulative selection has to add a little information to the genome at each step. But of all the mutations studied since genetics became a science, not a single one has been found that adds a little information. It is not impossible, in principle, for a mutation to add a little information, but it is improbable.
The NDT was an attractive theory. Unfortunately, it is based on the false speculation that many small random mutations could build up to large evolutionary changes. — Lee Spetner

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

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

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

Human rights are an aspect of natural law, a consequence of the way the universe works, as solid and as real as photons or the concept of pi. The idea of self- ownership is the equivalent of Pythagoras' theorem, of evolution by natural selection, of general relativity, and of quantum theory. Before humankind discovered any of these, it suffered, to varying degrees, in misery and ignorance. — L. Neil Smith

This, indeed, is the problem, the ultimate question, in neuroscience - and it cannot be answered, even in principle, without a global theory of brain function, one capable of showing the interactions of every level, from the micropatterns of individual neuronal responses to the grand macropatterns of an actual lived life. Such a theory, a neural theory of personal identity, has been proposed in the last few years by Gerald M. Edelman, in his theory of neuronal group selection, or neural Darwinism. — Oliver Sacks

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

Existing political philosophies all developed before evolutionary game theory, so they do not take equilibrium selection into account. Socialism pretends that individuals are not selfish sexual competitors, so it ignores equilibria altogether. Conservatism pretends that there is only one possible equilibrium - a nostalgic version of the status quo - that society could play. Libertarianism ignores the possibility of equilibrium selection at the level of rational social discourse, and assumes that decentralized market dynamics will magically lead to equilibria that yield the highest aggregate social benefits. Far from being a scientific front for a particular set of political views, modern evolutionary psychology makes most standard views look simplistic and unimaginitive. — Geoffrey Miller

In short, evolution is as close to being a scientific fact as is possible for any theory, given that science is open - ended and no one can predict with certainty what may change in the future. The prospect that evolution by natural selection, at least as a broad mechanism, will be overthrown in the future is about as likely as the prospect of finding out some day that the Earth is really flat. Unfortunately, those who regard these scientific facts as a threat to faith have chosen to distort and misrepresent them to the public. — Victor J. Stenger

I would give absolutely nothing for the theory of Natural Selection, if it requires miraculous additions at any one stage of descent. — Charles Darwin

If biologists have ignored self-organization, it is not because self-ordering is not pervasive and profound. It is because we biologists have yet to understand how to think about systems governed simultaneously by two sources of order, Yet who seeing the snowflake, who seeing simple lipid molecules cast adrift in water forming themselves into cell-like hollow lipid vesicles, who seeing the potential for the crystallization of life in swarms of reacting molecules, who seeing the stunning order for free in networks linking tens upon tens of thousands of variables, can fail to entertain a central thought: if ever we are to attain a final theory in biology, we will surely, surely have to understand the commingling of self-organization and selection. We will have to see that we are the natural expressions of a deeper order. Ultimately, we will discover in our creation myth that we are expected after all. — Stuart A. Kauffman

The theory of natural selection is the centerpiece of The Origin of Species and of evolutionary theory. It is this theory that accounts for the adaptations of organisms, those innumerable features that so wonderfully equip them for survival and reproduction; it is this theory that accounts for the divergence of species from common ancestors and thus for the endless diversity of life. Natural selection is a simple concept, but it is perhaps the most important idea in biology. — Douglas J. Futuyma

The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity. — Richard Dawkins

Common sense says that the amazing complexity of life cannot arise out of a random process. The neo-Darwinians use clever arguments to show why evolution should work and why common sense is wrong. One after the other of them has explained that although the variability occurs randomly, the selection process gives it direction and makes it nonrandom ... if the arguments were solid and correct they should have put the theory on a stable and reliable foundation. The neo-Darwinians would like everyone to believe they have done that. — Lee Spetner

The man that created the theory of evolution by natural selection was thrown out by his Dad because he wanted him to be a doctor. GAWD, parents haven't changed much. — Charles Darwin

A complete theory of evolution must acknowledge a balance between "external" forces of environment imposing selection for local adaptation and "internal" forces representing constraints of inheritance and development. Vavilov placed too much emphasis on internal constraints and downgraded the power of selection. But Western Darwinians have erred equally in practically ignoring (while acknowledging in theory) the limits placed on selection by structure and development what Vavilov and the older biologists would have called "laws of form. — Stephen Jay Gould

Darwinism is not a theory of random chance. It is a theory of random mutation plus non-random cumulative natural selection ... Natural selection ... is a non-random force, pushing towards improvement ... Every generation has its Darwinian failures but every individual is descended only from previous generations' successful minorities ... [T]here can be no going downhill - species can't get worse as a prelude to getting better ... There may be more than one peak. — Richard Dawkins

To suppose that the eye could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree — Charles Darwin

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

We can now expose perhaps the most common misunderstanding of Darwinism: the idea that Darwin showed that evolution by natural selection is a procedure for producing Us. Ever since Darwin proposed his theory, people have often misguidedly tried to interpret it as showing that we are the destination, the goal, the point of all that winnowing and competition, and our arrival on the scene was guaranteed by the mere holding of the tournament. This confusion has been fostered by evolution's friends and foes alike, and it is parallel to the confusion of the coin-toss tournament winner who basks in the misconsidered glory of the idea that since the tournament had to have a winner, and since he is the winner, the tournament had to produce him as the winner. Evolution can be an algorithm, and evolution can have produced us by an algorithmic process, without its being true that evolution is an algorithm for producing us. — Daniel C. Dennett

Throughout his last half-dozen books, for example, Arthur Koestler has been conducting a campaign against his own misunderstanding of Darwinism. He hopes to find some ordering force, constraining evolution to certain directions and overriding the influence of natural selection. [ ... ] Darwinism is not the theory of capricious change that Koestler imagines. Random variation may be the raw material of change, but natural selection builds good design by rejecting most variants while accepting and accumulating the few that improve adaptation to local environments. — Stephen Jay Gould

If we want to sum up the theory of evolution by natural selection in two words, which have great relevance for all societies and businesses, we should simply remember: diversity works. — Richard Koch

The Galapagos Islands are probably the most famous wildlife-watching destination in the world. And no wonder - it's almost impossible to exaggerate the sheer spectacle of the place that provided inspiration for Charles Darwin's ground-breaking theory of natural selection. — Mark Carwardine

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

To a certain extent, Darwinian gradualism is not much different from biblical creationism. This too is a collection of assumptions that has evolved into a belief system. The core idea advanced in the theory of evolution, the allegation that species have evolved along the time into different ones by the way of acquiring additional parts or by modifying the existing ones is based on an infinite of missing links, as in missing evidence, and on blind belief in the miracles of gradualism and natural selection. — Paul Greene

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

Perhaps many of the security analysts are handicapped by a flaw in their basic approach to the problem of stock selection. They seek the industries with the best prospects of growth, and the companies in these industries with the best management and other advantages. The implication is that they will buy into such industries and such companies at any price, however high, and they will avoid less promising industries and companies no matter how low the price of their shares. This would be the only correct procedure if the earnings of the good companies were sure to grow at a rapid rate indefinitely in the future, for then in theory their value would be infinite. And if the less promising companies were headed for extinction, with no salvage, the analysts would be right to consider them unattractive at any price. — Benjamin Graham

Dawkins recognizes the power irreducible complexity has to falsify naturalistic explanations (like any combination of chance, natural law, or natural selection). Even Charles Darwin acknowledged this dilemma when he wrote On the Origin of Species: "If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down."19 — J. Warner Wallace

To understand Darwin's work, you have to distinguish between his theory of descent and his theory of natural selection. THe full name of the first is the theory of descent with modification. Some call it the fact of evolution, and some call it the doctrine of evolution. — Lee Spetner

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

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

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

Memetics provides a new approach to the evolution of language in which we apply Darwinian thinking to two replicators, not one. On this theory, memetic selection, as well as genetic selection, does the work of creating language. — Susan Blackmore

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

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

I believe in the theory of evolution, but I believe as well in the allegorical truth of creation theory. In other words, I believe that evolution, including the principle of natural selection, is one of the tools used by God to create mankind. Mankind is then a participant in the creation of the universe itself, so that we have a closed loop. I believe that there is a level on which science and religious metaphor are mutually compatible. — Christopher Langan

... if we are uncritical we shall always find what we want: we shall look for, and find, confirmations, and we shall look away from, and not see, whatever might be dangerous to our pet theories. In this way it is only too easy to obtain what appears to be overwhelming evidence in favor of a theory which, if approached critically, would have been refuted. In order to make the method of selection by elimination work, and to ensure that only the fittest theories survive, their struggle for life must be made severe for them. — Karl R. Popper

Reflecting on my experience, I find myself agreeing with the eminent Cambridge philosopher, Dr C. D. Broad, 'that we should do well to consider much more seriously than we have hitherto been inclined to do the type of theory which Bergson put forward in connection with memory and sense perception. The suggestion is that the function of the brain and nervous system and sense organs is in the main eliminative and not productive. Each person is at each moment capable of remembering all that has ever happened to him and of perceiving everything that is happening everywhere in the universe. The function of the brain and nervous system is to protect us from being overwhelmed and confused by this mass of largely useless and irrelevant knowledge, by shutting out most of what we should otherwise perceive or remember at any moment, and leaving only that very small and special selection which is likely to be practically useful.' According — Aldous Huxley

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

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

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

On the theory of natural selection we can clearly understand the full meaning of that old canon in natural history, "Natura non facit saltum." This canon, if we look only to the present inhabitants of the world, is not strictly correct, but if we include all those of past times, it must by my theory be strictly true. — Charles Darwin

Natural selection is a theory of local adaptation to changing environments. It proposes no perfecting principles, no guarantee of general improvement — Stephen Jay Gould

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

Opponents say natural selection is not a theory supported by observation or experiment; that it is not based on fact; and that it cannot be proved. Well, no, you cannot prove the theory to people who won't believe in it any more than you can prove that the Battle of Hastings took place in 1066. However, we know the battle happened then, just as we know the course of evolution on earth unambiguously shows that Darwin was right. — David Attenborough

Anyone who writes about Darwin's theory of evolutionin the singular, without segregating the theories of gradual evolution, common descent, speciation, and the mechanism of natural selection, will be quite unable to discuss the subject competently. — Ernst Mayr

The theory of evolution by natural selection is an ecological theory-founded on ecological observation by perhaps the greatest of all ecologists. It has been adopted by and brought up by the science of genetics, and ecologists, being modest people, are apt to forget their distinguished parenthood. — John L. Harper

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

Scientific theories never dictate human values, but they can often cast new light on ethical issues. From a sexual selection viewpoint, moral philosophy and political theory have mostly been attempts to shift male human sexual competitiveness from physical violence to the peaceful accumulation of wealth and status. The rights to life, liberty, and property are cultural inventions that function, in part, to keep males from killing and stealing from one another while they compete to attract sexual partners. — Geoffrey Miller
