The falsifiability of the theory of evolution is a subject of dispute in the controversy between creationism and evolution. A falsifiable theory is a theory that can potentially be shown by evidence to be false. A charge leveled at evolution frequently by creationists is that evolution is not falsifiable, and therefore not a scientific theory. However, scientists counter that evolution, although as of yet unfalsified, is indeed falsifiable since many observations and tests of the validity of the theory are possible.

On the other hand, beliefs like creationism that dispute the theory of evolution are often classified as unfalsifiable.[1][2] At least in part, this is because creationism and similar philosophies are usually associated with religious positions. These sorts of beliefs often appeal to faith in lieu of evidence, making them unfalsifiable.[3]

Falsifiability was proposed by philosopher of science Karl Popper as a way to distinguish between science and pseudoscience, or between science and nonscience. The American justice system has employed falsifiability to decide what is and is not science, although falsifiability is not the only measure used by the judicial system.


Main article: Falsifiability

In science, a proposition is falsifiable if there is an observation or a test that could demonstrate that the statement is false.[4] Being falsifiable does not mean that an assertion is actually false, only that, if the theory were false, it would be possible to demonstrate as much with evidence.

The concept of falsifiability was introduced in 1934 by philosopher of science Karl Popper.[5] Popper sometimes described falsification and falsifiability in evolutionary terms, equating falsification with a type of natural selection or "survival of the fittest" for scientific ideas.[6] Popper wrote that the empirical method does not determine the truth of a theory, and that the goal of the scientific method is "not to save the lives of untenable systems, but, on the contrary, to select the one which is by comparison the fittest, by exposing them all to the fiercest struggle for survival."[5][7] Popper regarded falsifiability as synonymous with refutability or testability,[4] although some discussions of falsifiability describe it as a component of testability[8] or a related concept.[9]

Falsifiability was advanced as a method for solving the demarcation problem—that is, for deciding what is and what is not science.[4] Falsifiability was proposed by Popper as a replacement for the earlier principle of verifiability espoused by the Vienna Circle of philosphers of science.[6][10] This principle stated that a theory was meaningful and scientific if it was empirically verifiable, according to the "verifiability theory of meaning".[11]

Other philosophers and scientists have disputed Popper's falsifiability criterion as being inadequate and unrealistic.[12][13][14] For example, among those who have argued that falsifiability does not really describe the way science operates, or otherwise criticized it, are Rebecca Goldstein,[15] David Papineau,[16] Theodore Schick Jr,[17] Thomas Kuhn,[10] Ernest Nagel,[18] Imre Lakatos,[19] Larry Laudan,[11][20][21] Paul R. Thagard,[22] Paul Feyerabend[23] and Alan Sokal and Jean Bricmont.[24][25] Debate among some scientists and philosophers of science on the applicability of falsifiability in science continues.[26][27]

Falsifiability in biology[edit]

Popper is one of the few philosophers of science that have actually influenced scientists, including biologists. Falsifiability and other philosophical ideas of Popper have played a role in disputes among scientists and nonscientists alike, including disagreements about biology.[9] In spite of this, there is no general agreement on the usefulness of falsifiability in biology.[28][9]

One of the main applications of falsifiability in biology is as a lens through which to understand the character of evolution. Popper even proposed some falsifiable "improvements" to the theory of evolution, but they were ignored for the most part.[9] William Saletan of Slate magazine argues that the feature that makes evolution falsifiable is the goal of explaining the mechanisms of evolution. If one version of evolutionary theory fails, another explanation must be created and tested.[29] The process of modifying and replacing outdated or superceded theories of evolution is prima facie evidence that evolution is falsifiable.[12]

Evolution and falsifiability[edit]

Popper and the falsifiability of evolution[edit]

Hasn't Popper argued that evolution is not really respectable science, that it's all some rather boring tautology and is not to be taken terribly seriously? – Lewis Wolpert.

Well, I think Popper himself would (a) claim that he never said it, and (b) claim that if he did say it, he didn't mean it. – John Maynard Smith (1920-2004).[30]

The "father of falsifiability", Karl Popper, originally was skeptical that evolution was falsifiable. In 1957, Popper wrote that common descent was only a hypothesis, "not a universal law".[31] He again described his disdain for "evolutionary laws" in 1962,[32] a sentiment shared at that time by most NeoDarwinists[33][34] about the dozens of evolutionary laws formulated in the 19th century such as Dollo's law, Lamarck's laws and the Biogenetic law,[35] many of which were subsequently discarded by mainstream biology.[36] In 1972, Popper described his main objection to evolutionary theory: that natural selection is a tautology, or at least "almost tautological, because those that survive are defined as those that are fit enough to survive.[37][38][39] Since tautologies are not falsifiable, and in Popper's formulation, falsifiability is necessary for a theory to be scientific, Popper's classification of evolutionary theory was unclear.[9]

Popper clarified his position on evolution in his 1974 autobiography by writing, "Darwinism is not a testable scientific theory, but a metaphysical research program".[39] However, Popper only included natural selection in his conception of "Darwinism", and not the other mechanisms of evolution (p. 170 of Unended Quest, K. Popper, 1974).[39][40] For Popper, a "metaphysical research program" is a set of assumptions and world-views that underlie scientific research.[41][39] This is a different definition of the term "metaphysics" than that used by the logical positivists, a group of philosophers opposed by Popper who describe metaphysics as a meaningless search for answers to questions that cannot be answered.[42] The confusion created by these two different definitions of the term "metaphysics" was and is exploited by those opposed to evolution. In fact, Popper wrote admiringly of the value of Darwin's theory, saying that "Although it is metaphysical, it sheds much light upon very concrete and very practical researches".[43][44] Popper described evolution as having a "scientific character" (pages 168 and 172 of Unended Quest, K. Popper, 1974).[45]

However, opponents of evolutionary theory seized upon Popper's statements to proclaim that evolutionary theory is unscientific, and assert that creationism is an equally valid "metaphysical research program".[46][47][48] For example, Duane Gish, a leading creationist, wrote in a letter to Discover magazine, published in the July 1981 issue:

Stephen Jay Gould states that creationists claim creation is a scientific theory. This is a false accusation. Creationists have repeatedly stated that neither creation nor evolution is a scientific theory (and each is equally religious).[49][50]

Popper responded to these creationist claims by affirming that evolutionary theories regarding the origins of life on earth were scientific because "their hypotheses can in many cases be tested".[45] However, creationists answered Popper's statements by pointing out that Popper had not classified common descent as testable. Some creationists claimed that common descent would never be testable.[51][52]

Popper recanted his views more formally in 1978,

I have changed my mind about the testability and logical status of the theory of natural selection; and I am glad to have an opportunity to make a recantation".[53][54]

However, Popper still maintained that natural selection was more of a research program, but one that was testable and therefore not a tautology.[55] In spite of Popper's change of mind, many creationists continue to quote Popper's description of evolution as a "metaphysical research program" as one of their objections to evolution.[56]

Creationist criticisms of evolution's falsifiability[edit]

Main article: Objections to evolution

Creationists have frequently alleged that evolution is unfalsifiable. Among the complaints of creationists are:

  1. Any fact can be fit in the evolutionary framework[57][58][59]
  2. All traits can be explained as either an adaptation or an exaptation (Steve Fuller).[60][61][62]
  3. Evolution is defined to occur whenever genetic distributions change and depart from a Hardy-Weinberg equilibrium, and since this equilibrium never exists in practice, evolution always occurs by definition (Steve Fuller)[60][61][62]
  4. Natural selection, or "survival of the fittest", is a tautology, i.e., something that is true by definition, a truism.[63][64][39]
  5. Darwinism is effectively unfalsifiable, since one would have to show that every conceivable biological pathway could not have lead to a biological structure (William Dembski).[8]
  6. Instead of falsification, evolution supporters argue that an evolutionary process must have created every observed structure, but that science is ignorant of the details of this process (William Dembski).[8]
  7. "Darwinism is not a testable scientific theory but a metaphysical research programme." (Karl Popper)[39][65][66][56]
  8. To falsify the claim that “Some unintelligent process (involving natural selection and random mutation) could produce this system”, "one would have to show the system could not have been formed by any of a potentially infinite number of possible unintelligent processes, which is effectively impossible to do." (Michael Behe)[67]
  9. One must show that no conceivable Darwinian pathway could have led to a given biological structure, which is impossible.[8]
  10. Evolutionary scientists retreat into "historical contingency" by claiming that there is no guarantee that one can reconstruct the pathways that occured in the past.[8]
  11. When Michael Behe suggested that the bacterial flagellum was irreducibly complex, "Darwinists" felt they could find a Darwinian pathway although one was not known.[8]
  12. Evolution is a historical science, and is unrepeatable and therefore untestable.[59][68]
  13. Evolution is too slow to observe, so it is untestable.[69]

Creationists commonly use quote mining to bolster their case that evolution is not falsifiable.[70][71] For example, a commonly used misleading and selective quote[72][73] which is used to suggest evolution is unfalsifiable is taken from a publication of Paul Ehrlich and L. C. Birch:

Our theory of evolution ... cannot be refuted by any possible observations. Every conceivable observation can be fitted into it. It is thus 'outside of empirical science' but not necessarily false. No one can think of ways to test it. Ideas either without basis or based on a few laboratory experiments carried out in extremely simplified systems have obtained currency far beyond their validity. They have become part of an evolutionary dogma accepted by most of us as part of our training.[74]

However, the quote miners typically leave out the following sentence, The cure seems to us not to be a discarding of the modern synthesis of evolutionary theory, but more skepticism about many of its tenets[74] or the introduction to the article:

While accepting evolutionary theory, should ecologists be more skeptical about hypotheses derived solely from untestable assumptions about the past? The authors put forward the view that many ecologists underestimate the efficacy of natural selection and fail to distinguish between phylogenetic and ecological questions.[74]

which demonstrate that the authors are not arguing that evolution is untestable at all, but are arguing that their colleagues should not look at historical data as much as current observations.[75]

Proposed methods of testing evolutionary theory[edit]

The most famous example of a falsifiability test of evolutionary theory concerns finding fossil remains of a rabbit tens of millions of years old. For example, Richard Dawkins, biologist and professor at Oxford University, explained that "If there were a single hippo or rabbit in the Precambrian, that would completely blow evolution out of the water. None have ever been found."[76] Similarly, the evolutionary biologist J.B.S. Haldane, when asked what hypothetical evidence could disprove evolution, replied "fossil rabbits in the Precambrian era"[77], a period more than 540 million years ago, when life on Earth consisted largely of bacteria, algae, and plankton.

There are many other potential tests of evolution.[78] For example:

  1. the stable existence of inefficient species in the presence of better adapted species.[79]
  2. the existence of a complex organ that could not be formed by successive minor modifications (Charles Darwin)[80]
  3. a structure which had been formed to satisfy human aesthetic senses, or for variety[80]
  4. a structure in one species created exclusively for the good of another species[80]
  5. sudden appearance of species[80]
  6. a perfect geologic record, with no gaps or missing transitions[80]
  7. change of organisms that violate laws of genetics, ontogeny, and molecular biology[79]
  8. new species emerging without ancestral species[79]
  9. a fossil of a Tyrannosaurus rex with a human head in its jaws (Peter Ward)[81]
  10. A fossil of a monkey in the Ordovician.[81]
  11. a fossil record that is temporally homogeneous [58]
  12. chimeras[58]
  13. something that blocks mutations from aggregating[58]
  14. direct observation of an organism's creation[58]
  15. A human fossil 10 million years older than any vertebrate fossil (Lewis Wolpert)[60][61]
  16. The existence of an animal on Earth that functions on different principles, not having DNA or proteins (Lewis Wolpert).[60][61][62]
  17. The existence of a fish with fingers that it uses to catch other fish (Lewis Wolpert).[60][61]
  18. Native land mammals on oceanic islands (H. Allen Orr)[82]
  19. Finding a hominid fossil in the Precambrian (Jerry Coyne)[2]
  20. finding the remains of a car in Cambrian sediments.[83]
  21. hominid fossils found in the same geological strata as trilobites (Michael Shermer)[84][85]
  22. a constant or static fossil record[86]
  23. The existence of non-DNA-based life falsifies common descent.[86]
  24. sudden appearance of a new species[86]
  25. Perfect copying of DNA from one generation to the next[86]
  26. Variation created by something besides errors in replication or environmental mitogens[86]
  27. Finding fossils in places that were unexpected or could not be explained.[86]
  28. Finding that acquired traits in any species can be inherited falsifies natural selection's role as the main evolutionary mechanism.[86]
  29. All organisms have the same number of offspring[87]
  30. There is no difference between the organisms that survive and those that do not.[87]
  31. Discovery of modern human fossils dating back to 65 million years ago.[87]
  32. no continuity in genes[8]
  33. Nonexistence of a splice in a human chromosome (Kenneth Miller)[88]
  34. irreducible complexity[86]
  35. lack of invasive species[89]
  36. the mean characteristics of a population under selection pressure do not change in the predicted way (Massimo Pigliucci)[54]
  37. the "Meister Prints" of human bootprints together with trilobite fossils are genuine and created at the same time[90][91]
  38. evidence demonstrating that the current understanding of phylogenetic tree structure is completely false[78]
  39. fossilized human skeletons found among undisturbed Jurassic fossils[92]
  40. "organisms that will sacrifice their own reproductive success in order to enhance the reproductive success of some other species"[92]

Evolution's falsifiability in law and society[edit]

Falsifiability was one of the criteria used by Judge William Overton to determine that "creation science" was not scientific and should not be taught in Arkansas public schools. In McLean v. Arkansas, Overton ruled on Act 590 "The Arkansas Balanced Treatment Act," which was a law requiring the teaching of creation science in classrooms. This statute provided for the equal treatment of creation science and the theory of evolution in science classrooms.[93][94][95]

When Judge Overton struck down the Act in 1982, he decided that "creation science" was not science, using the following critera:

More precisely, the essential characteristics of science are:

  1. It is guided by natural law;
  2. It has to be explanatory by reference to nature law;
  3. It is testable against the empirical world;
  4. Its conclusions are tentative, i.e. are not necessarily the final word; and
  5. It is falsifiable.[96]

Overton's ruling was criticized by philosopher Larry Laudan, who disagreed with philosopher Michael Ruse about the value of this Overton decision.[20][21]

Falsifiability was also further enshrined in United States law as part of the Daubert Standard created by the United States Supreme Court in 1993 as a criteria for deciding which scientific evidence is admissible in a jury trial,[97] replacing the older Frye Standard which was established in 1923. For scientific evidence to be admissible, it has satisfy the "reliability prong," that is, it has to be scientifically valid.[98]

The Supreme Court explained that in order for expert testimony to be considered reliable, the expert must have derived his or her conclusions using the scientific method.[99] The Court offered "general observations" of whether proffered evidence was based on the scientific method, although the list was not intended to be used as an exacting checklist:[100]

  1. Empirical testing: the theory or technique must be falsifiable, refutable, and testable.
  2. Subjected to peer review and publication.
  3. Known or potential error rate.
  4. Standards controlling the technique's operations.
  5. The theory and technique is generally accepted by a relevant scientific community.[101][102]

Chief Justice William Rehnquist wrote the dissenting opinion when the Daubert decision was adopted, admitting that he did not understand falsifiability, and suggesting that other judges would have trouble as well.[103][100] Some legal scholars have criticized the Daubert Standard as misrepresenting the scientific enterprise, and unfairly rejecting scientific experts.[99]

The Daubert Standard was quoted extensively in an amicus curiae brief filed by several pro-evolution groups in the Selman v. Cobb County School District court case.[104] This led to a decision against evolution textbook disclaimer stickers, issued January 13, 2005.[105][106]

The Daubert Standard was also part of the Kitzmiller v. Dover trial associated with intelligent design creationism.[107][108] It was part of the discussion about admission of the testimony of expert witnesses,[109] and some claimed it did not form part of the decision.[110] However, Charles Kitcher noted that Judge John E. Jones' Kitzmiller decision drew on the three applicable Daubert factors, without mentioning Daubert explicitly:[111] "ID has failed to gain acceptance in the scientific community, it has not generated peer reviewed publications, nor has it been the subject of testing and research."[112]

Kitcher argued that since intelligent design is "untestable, unsupported in the peer review literature, and rejected by the scientific community, it is insufficiently reliable under Daubert." Kitcher also advocates creating a new standard for admitting scientific evidence that includes the Daubert Standard.[111][113]

Several associated with the Discovery Institute, the main promoter of intelligent design, wrote a book criticizing Judge Jones for misapplying the Daubert Standard in the Kitzmiller v. Dover case, after Jones issued a decision which was not favorable to intelligent design.[114][115] One of the authors, Casey Luskin of the Discovery Institute, wrote some polemics attacking Jones, including at least one using quote mined text from the amicus curiae brief signed by paleontologist Stephen Jay Gould submitted in the original Daubert v. Merrell Dow Pharmaceuticals Supreme Court case that produced the Daubert Standards.[116][117][118]

Creationism and falsifiability[edit]

It is sometimes claimed that creationism, creation science, intelligent design and related ideas are not falsifiable.[1][2][86][119][113] Philosopher Robert Pennock noted in his expert report for the Kitzmiller v. Dover trial that intelligent design is untestable:

A god that is all-powerful and whose will is inscrutable can be called upon to “explain” any event in any situation, and this is one reason for science’s methodological prohibition against such appeals. Leaving the designer unnamed and undescribed has the same effect. Given this feature, supernatural hypotheses remain immune from disconfirmation or meaningful testing.[120]

Karl Popper wrote that creationism "was worse than an open admission of failure, for it created the impression that an ultimate explanation had been reached" (p. 172 of Unended Quest, K. Popper, 1974).[39]

One of the main components of intelligent design, Lehigh University biochemist Michael J. Behe's theory of irreducible complexity, has been described as unfalsifiable.[29][86] For example, Anne Marie Lofaso, Adjunct Associate Professor at American University's Washington College of Law, writes "ID is not falsifiable, in part because it is subject to ad hoc explanations. Indeed, ID’s poster child for irreducibly complex systems, the bacterial flagellum, does not show that ID is falsifiable." Lofasa argues that any of Behe's tests for irreducible complexity could be foiled by the actions of an omnipotent intelligent agent.[86]

Philosopher Neil Tennant suggests that the tenets of intelligent design have been fashioned to avoid scientific scrutiny, often the downfall of previous creationist theories. However, this lack of scrutiny comes at the cost of being unfalsifiable, and therefore unscientific according to Tennant, altough its proponents claim otherwise:

They have pared their theory down to the point where it cannot actually be brought into confrontation with any observable facts. It therefore cannot be dismissed as a sub-optimal explanation of what can be observed—because it does not really explain (or predict) anything. Heady with that triumph in avoiding direct refutation, they continue to claim scientific status for ID-theory... [120]

The Kansas Board of Education approved new science standards on November 8, 2005. These new standards defined science to be falsifiable as well as including supernatural causes for natural phenomena,[86][121][122][123] which are incompatible requirements according to Lofaso.[86]

In addition, Lofaso asserts that intelligent design is a tautology, and therefore unfalsifiable:

Along these lines, the design inference is tautological, because it assumes what it tries to prove – observable design must have a designer. Accordingly, the tautology actually has no explanatory power, in the sense that it cannot predict outcomes.[86]

Philosopher Larry Laudan maintains that not only is creationism falsifiable, but that it has been falsified repeatedly.[11][20][21] Philosopher Neil Tennant described Laudan's views as naive, since it is impossible to falsify creationist ideas by empirical means, given their religious purpose.[120] Laudan counters that there is no easy demarcation principle that is possible for distinguishing science from nonscience, and in particular creationism from science. Creationism can meet standards of falsifiability and revisability and many other requirements easily.[11][20][21]

It is also frequently stated that the available evidence does not support creationist ideas, so they appear to be false.[20][21] It has been pointed out that it is contradictory to say that these beliefs are unfalsifiable, and false at the same time.[67][59] Evolution supporters note that the same inconsistent complaints are made by creationists of evolution.[58][75] However, X noted that the difference is that science abandons ideas that are falsified, while creationism does not.

Many of the leading figures of young earth creationism, creation science and other types of traditional creationism have stated clearly that creationism is untestable. For example, creation scientists Duane Gish and Henry M. Morris of the Institute of Creation Research have published statements that amount to declarations that creationism is unfalsifiable.[124][125][50][126] Loma Linda University Geoscience Research Institute members Ariel Roth and Harold Coffin testified that creation science is not testable as expert witnesses for the defense in the McLean v. Arkansas trial.[127] By contrast, several of the most prominent neocreationists, Michael Behe, William Dembski and Stephen C. Meyer argue that intelligent design, another form of creationism, is falsifiable and therefore scientific.[8][67][59][69]

One of the main complaints raised against traditional creationists is that they will not give up their beliefs, even after they have been falsified.[20][citation needed] This is a characteristic they share with some of the neocreationists. For example, Dembski states that even if Darwinian explanations are found for the gaps in our knowledge that intelligent design is supposed to fill, this won't disprove intelligent design.[8] Meyer similarly reports that "Indeed, many biologists who favor design now make their case for it on the basis of its ability to explain the same evidences that descent can as well as some that descent allegedly cannot (such as the presence of sequentially encoded information in DNA)."[59]

Meyer also argues that evolution and intelligent design are "methodologically equivalent", in the sense that if one is falsifiable, they both are, and if one is unfalsifiable, they both are. Meyer states that if intelligent design is labelled a "quasi-scientific historical speculation with strong metaphysical overtones", the same label must be applied to evolution.[59]

Meyer tries to answer the complaint that the acceptance of intelligent design will stultify scientific inquiry by answering easily all unanswered questions.[128][129] Meyer remarks that evolution already fulfills this role, which is one of the main reasons creationists claim evolution is unfalsifiable.[58][57] Meyer responds to the complaint by stating that intelligent design is only appropriately of use in historical contexts, when "theologically plausible", and when natural causes or other possible action have not yet been successful in producing an explanation.[59]

  37. ^ "Quite apart from evolutionary philosophies, the trouble about evolutionary theory is its tautological, or almost tautological, character: the difficulty is that Darwinism and natural selection, though extremely important, explain evolution by 'the survival of the fittest' (a term due to Herbert Spencer). Yet there does not seem to be much difference, if any, between the assertion 'those that survive are the fittest' and the tautology 'those that survive are those that survive'. For we have, I am afraid, no other criterion of fitness than actual survival, so that we conclude from the fact that some organisms have survived that they were the fittest, or those best adapted to the conditions of life." from pages 241-242 of Objective Knowledge: An Evolutionary Approach, Karl Popper, At the Clarendon Press, Oxford, 1972, ISBN 0198750242 .

Popper, 1974).

In trying to explain experiments with bacteria which become adapted to, say, penicillin, it is quite clear that we are greatly helped by the theory of natural selection. Although it is metaphysical, it sheds much light upon very concrete and very practical researches. It allows us to study adaptation to a new environment (such as a penicillin-infested environment) in a rational way: it suggests the existence of a mechanism of adaptation, and it allows us even to study in detail the mechanism at work. And it is the only theory so far which does all that." (p. 171-172 of Unended Quest, K. Popper, 1974).

There seem to be exceptions, as with so many biological theories; and considering the random character of the variations on which natural selection operates, the occurrence of exceptions is not surprising. Thus not all phenomena of evolution are explained by natural selection alone. Yet in every particular case it is a challenging research programme to show how far natural selection can possibly be held responsible for the evolution of a particular organ or behavioural programme" (Natural selection and the emergence of mind, K.

  124. ^ "Creation ... is inaccessible to the scientific method. It is impossible to devise a scientific experiment to describe the creation process, or even to ascertain whether such a process can take place. The Creator does not create at the whim of a scientist.", page 5 of Scientific Creationism, Henry M. Morris, Master Books, 1985, ISBN 0890510032
  125. ^ We do not know how the creator (sic) created, what processes He used, for He used processes which are not now operating anywhere in the natural universe. This is why we refer to creation as special creation. We cannot discover by scientific investigation anything about the creative processes used by the Creator., page 42 of Evolution: the Fossils Say No!, Duane Gish, Master Books, 1979, ISBN 0890510466
  126. ^ "Creation is, of course, unproven and unproveable by the methods of experimental science. Neither can it qualify, according to the above criteria, as a scientific theory, since creation would have been unobservable and would as a theory be nonfalsifiable.", page 21 of Evolution: the Fossils Say No!, Duane Gish, Master Books, 1979, ISBN 0890510466
  127. ^ "creation science is not testable scientifically." (Harold Lewin); In response to a query asking if creation science is a science, "If you want to define 'science' as testable, predictable, I would say no." (Ariel Roth); from Where Is the Science in Creation Science?, Roger Lewin, Science, Volume 215, Number 4529, pages 142-144, January 8, 1982, DOI 10.1126 / science.215.4529.142
  128. ^ For example, Eugenie Scott, Executive Director of the National Center for Science Education, states that, "Intelligent design is a science stopper. It stops science in its tracks because you stop looking" (Evolution and Intelligent Design, Episode no. 504, Religion and Ethics Newsweekly, Public Broadcasting System website, September 28, 2001). Kenneth R. Miller, Brown University biology professor, states that, "So by placing the supernatural as a cause in science, you effectively have what you might call a science-stopper. If you attribute an event to the supernatural, you can by definition investigate it no further" (In Defense of Evolution, Interview of Kenneth R. Miller conducted on April 19, 2007 by Joe McMaster, producer of "Judgment Day: Intelligent Design on Trial," and edited by Lauren Aguirre and Peter Tyson, executive editor and editor in chief of NOVA online, Public Broadcasting System website).
