Case 4:04-cv-02688-JEJ Document 342 Filed 12/20/2005
We have now found that both an objective student and an objective adult member of the Dover community would perceive Defendants’ conduct to be a strong endorsement of religion pursuant to the endorsement test. Having so concluded, we find it incumbent upon the Court to further address an additional issue raised by Plaintiffs, which is whether ID is science. To be sure, our answer to this question can likely be predicted based upon the foregoing analysis. While answering this question compels us to revisit evidence that is entirely complex, if not obtuse, after a six week trial that spanned twenty-one days and included countless hours of detailed expert witness presentations, the Court is confident that no other tribunal in the United States is in a better position than are we to traipse into this controversial area. Finally, we will offer our conclusion on whether ID is science not just because it is essential to our holding that an Establishment Clause
Page 64 of 139
violation has occurred in this case, but also in the hope that it may prevent the obvious waste of judicial and other resources which would be occasioned by a subsequent trial involving the precise question which is before us.
4. Whether ID is Science
After a searching review of the record and applicable caselaw, we find that while ID arguments may be true, a proposition on which the Court takes no position, ID is not science. We find that ID fails on three different levels, any one of which is sufficient to preclude a determination that ID is science. They are: (1) ID violates the centuries-old ground rules of science by invoking and permitting supernatural causation; (2) the argument of irreducible complexity, central to ID, employs the same flawed and illogical contrived dualism that doomed creation science in the 1980's; and (3) ID’s negative attacks on evolution have been refuted by the scientific community. As we will discuss in more detail below, it is additionally important to note that 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. Expert testimony reveals that since the scientific revolution of the 16th and 17th centuries, science has been limited to the search for natural causes to explain natural phenomena. (9:19-22 (Haught); 5:25-29 (Pennock); 1:62 (Miller)). This
Page 65 of 139
revolution entailed the rejection of the appeal to authority, and by extension, revelation, in favor of empirical evidence. (5:28 (Pennock)). Since that time period, science has been a discipline in which testability, rather than any ecclesiastical authority or philosophical coherence, has been the measure of a scientific idea’s worth. (9:21-22 (Haught); 1:63 (Miller)). In deliberately omitting theological or “ultimate” explanations for the existence or characteristics of the natural world, science does not consider issues of “meaning” and “purpose” in the world. (9:21 (Haught); 1:64, 87 (Miller)). While supernatural explanations may be important and have merit, they are not part of science. (3:103 (Miller); 9:19-20 (Haught)). This self-imposed convention of science, which limits inquiry to testable, natural explanations about the natural world, is referred to by philosophers as “methodological naturalism” and is sometimes known as the scientific method. (5:23, 29-30 (Pennock)). Methodological naturalism is a “ground rule” of science today which requires scientists to seek explanations in the world around us based upon what we can observe, test, replicate, and verify. (1:59-64, 2:41-43 (Miller); 5:8, 23-30 (Pennock)).
As the National Academy of Sciences (hereinafter “NAS”) was recognized by experts for both parties as the “most prestigious” scientific association in this country, we will accordingly cite to its opinion where appropriate. (1:94, 160-61
Page 66 of 139
(Miller); 14:72 (Alters); 37:31 (Minnich)). NAS is in agreement that science is limited to empirical, observable and ultimately testable data: “Science is a particular way of knowing about the world. In science, explanations are restricted to those that can be inferred from the confirmable data – the results obtained through observations and experiments that can be substantiated by other scientists. Anything that can be observed or measured is amenable to scientific investigation. Explanations that cannot be based upon empirical evidence are not part of science.” (P-649 at 27).
This rigorous attachment to “natural” explanations is an essential attribute to science by definition and by convention. (1:63 (Miller); 5:29-31 (Pennock)). We are in agreement with Plaintiffs’ lead expert Dr. Miller, that from a practical perspective, attributing unsolved problems about nature to causes and forces that lie outside the natural world is a “science stopper.” (3:14-15 (Miller)). As Dr. Miller explained, once you attribute a cause to an untestable supernatural force, a proposition that cannot be disproven, there is no reason to continue seeking natural explanations as we have our answer. Id.
ID is predicated on supernatural causation, as we previously explained and as various expert testimony revealed. (17:96 (Padian); 2:35-36 (Miller); 14:62 (Alters)). ID takes a natural phenomenon and, instead of accepting or seeking a
Page 67 of 139
natural explanation, argues that the explanation is supernatural. (5:107 (Pennock)). Further support for the conclusion that ID is predicated on supernatural causation is found in the ID reference book to which ninth grade biology students are directed, Pandas. Pandas states, in pertinent part, as follows:
- Darwinists object to the view of intelligent design because it does not give a natural cause explanation of how the various forms of life started in the first place. Intelligent design means that various forms of life began abruptly, through an intelligent agency, with their distinctive features already intact – fish with fins and scales, birds with feathers, beaks, and wings, etc. P-11 at 99-100 (emphasis added).
Stated another way, ID posits that animals did not evolve naturally through evolutionary means but were created abruptly by a non-natural, or supernatural, designer. Defendants’ own expert witnesses acknowledged this point. (21:96-100 (Behe); P-718 at 696, 700 (“implausible that the designer is a natural entity”); 28:21-22 (Fuller) (“. . . ID’s rejection of naturalism and commitment to supernaturalism . . .”); 38:95-96 (Minnich) (ID does not exclude the possibility of a supernatural designer, including deities).
It is notable that defense experts’ own mission, which mirrors that of the IDM itself, is to change the ground rules of science to allow supernatural causation of the natural world, which the Supreme Court in Edwards and the court in McLean correctly recognized as an inherently religious concept. Edwards, 482
Page 68 of 139
U.S. at 591-92; McLean, 529 F. Supp. at 1267. First, defense expert Professor Fuller agreed that ID aspires to “change the ground rules” of science and lead defense expert Professor Behe admitted that his broadened definition of science, which encompasses ID, would also embrace astrology. (28:26 (Fuller); 21:37-42 (Behe)). Moreover, defense expert Professor Minnich acknowledged that for ID to be considered science, the ground rules of science have to be broadened to allow consideration of supernatural forces. (38:97 (Minnich)).
Prominent IDM leaders are in agreement with the opinions expressed by defense expert witnesses that the ground rules of science must be changed for ID to take hold and prosper. William Dembski, for instance, an IDM leader, proclaims that science is ruled by methodological naturalism and argues that this rule must be overturned if ID is to prosper. (5:32-37 (Pennock)); P-341 at 224 (“Indeed, entire fields of inquiry, including especially in the human sciences, will need to be rethought from the ground up in terms of intelligent design.”). The Discovery Institute, the think tank promoting ID whose CRSC developed the Wedge Document, acknowledges as “Governing Goals” to “defeat scientific materialism and its destructive moral, cultural and political legacies” and “replace materialistic explanations with the theistic understanding that nature and human beings are created by God.” (P-140 at 4). In addition, and as previously
Page 69 of 139
noted, the Wedge Document states in its “Five Year Strategic Plan Summary” that the IDM’s goal is to replace science as currently practiced with “theistic and Christian science.” Id. at 6. The IDM accordingly seeks nothing less than a complete scientific revolution in which ID will supplant evolutionary theory.14 Notably, every major scientific association that has taken a position on the issue of whether ID is science has concluded that ID is not, and cannot be considered as such. (1:98-99 (Miller); 14:75-78 (Alters); 37:25 (Minnich)). Initially, we note that NAS, the “most prestigious” scientific association in this country, views ID as follows: Creationism, intelligent design, and other claims of supernatural intervention in the origin of life or of species are not science because they are not testable by the methods of science. These claims subordinate observed data to statements based on authority, revelation, or
- 14 Further support for this proposition is found in the Wedge Strategy, which is composed of three phases: Phase I is scientific research, writing and publicity; Phase II is publicity and opinion-making; and Phase III is cultural confrontation and renewal. (P-140 at 3). In the “Five Year Strategic Plan Summary,” the Wedge Document explains that the social consequences of materialism have been “devastating” and that it is necessary to broaden the wedge with a positive scientific alternative to materialistic scientific theories, which has come to be called the theory of ID. “Design theory promises to reverse the stifling dominance of the materialist worldview, and to replace it with a science consonant with Christian and theistic convictions.” Id. at 6. Phase I of the Wedge Strategy is an essential component and directly references “scientific revolutions.” Phase II explains that alongside a focus on influential opinion-makers, “we also seek to build up a popular base of support among our natural constituency, namely, Christians. We will do this primarily through apologetics seminars. We intend these to encourage and equip believers with new scientific evidence that support the faith, as well as to ‘popularize’ our ideas in the broader culture.” Id. Finally, Phase III includes pursuing possible legal assistance “in response to resistance to the integration of design theory into public school science curricula.” Id. at 7.
Page 70 of 139
religious belief. Documentation offered in support of these claims is typically limited to the special publications of their advocates. These publications do not offer hypotheses subject to change in light of new data, new interpretations, or demonstration of error. This contrasts with science, where any hypothesis or theory always remains subject to the possibility of rejection or modification in the light of new knowledge. P-192 at 25. Additionally, the American Association for the Advancement of Science (hereinafter “AAAS”), the largest organization of scientists in this country, has taken a similar position on ID, namely, that it “has not proposed a scientific means of testing its claims” and that “the lack of scientific warrant for so-called ‘intelligent design theory’ makes it improper to include as part of science education. . .” (P-198). Not a single expert witness over the course of the six week trial identified one major scientific association, society or organization that endorsed ID as science. What is more, defense experts concede that ID is not a theory as that term is defined by the NAS and admit that ID is at best “fringe science” which has achieved no acceptance in the scientific community. (21:37-38 (Behe); Fuller Dep. at 98-101, June 21, 2005; 28:47 (Fuller); Minnich Dep. at 89, May 26, 2005). It is therefore readily apparent to the Court that ID fails to meet the essential ground rules that limit science to testable, natural explanations. (3:101-03 (Miller); 14:62 (Alters)). Science cannot be defined differently for Dover students than it is defined in the scientific community as an affirmative action program, as advocated
Page 71 of 139
by Professor Fuller, for a view that has been unable to gain a foothold within the scientific establishment. Although ID’s failure to meet the ground rules of science is sufficient for the Court to conclude that it is not science, out of an abundance of caution and in the exercise of completeness, we will analyze additional arguments advanced regarding the concepts of ID and science.
ID is at bottom premised upon a false dichotomy, namely, that to the extent evolutionary theory is discredited, ID is confirmed. (5:41 (Pennock)). This argument is not brought to this Court anew, and in fact, the same argument, termed “contrived dualism” in McLean, was employed by creationists in the 1980's to support “creation science.” The court in McLean noted the “fallacious pedagogy of the two model approach” and that “[i]n efforts to establish ‘evidence’ in support of creation science, the defendants relied upon the same false premise as the two model approach . . . all evidence which criticized evolutionary theory was proof in support of creation science.” McLean, 529 F. Supp. at 1267, 1269. We do not find this false dichotomy any more availing to justify ID today than it was to justify creation science two decades ago.
ID proponents primarily argue for design through negative arguments against evolution, as illustrated by Professor Behe’s argument that “irreducibly complex” systems cannot be produced through Darwinian, or any natural,
Page 72 of 139
mechanisms. (5:38-41 (Pennock); 1:39, 2:15, 2:35-37, 3:96 (Miller); 16:72-73 (Padian); 10:148 (Forrest)). However, we believe that arguments against evolution are not arguments for design. Expert testimony revealed that just because scientists cannot explain today how biological systems evolved does not mean that they cannot, and will not, be able to explain them tomorrow. (2:36-37 (Miller)). As Dr. Padian aptly noted, “absence of evidence is not evidence of absence.” (17:45 (Padian)). To that end, expert testimony from Drs. Miller and Padian provided multiple examples where Pandas asserted that no natural explanations exist, and in some cases that none could exist, and yet natural explanations have been identified in the intervening years. It also bears mentioning that as Dr. Miller stated, just because scientists cannot explain every evolutionary detail does not undermine its validity as a scientific theory as no theory in science is fully understood. (3:102 (Miller)).
As referenced, the concept of irreducible complexity is ID’s alleged scientific centerpiece. Irreducible complexity is a negative argument against evolution, not proof of design, a point conceded by defense expert Professor Minnich. (2:15 (Miller); 38:82 (Minnich) (irreducible complexity “is not a test of intelligent design; it’s a test of evolution”). Irreducible complexity additionally fails to make a positive scientific case for ID, as will be elaborated upon below.
Page 73 of 139
We initially note that irreducible complexity as defined by Professor Behe in his book Darwin’s Black Box and subsequently modified in his 2001 article entitled “Reply to My Critics,” appears as follows:
- By irreducibly complex I mean a single system which is composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning. An irreducibly complex system cannot be produced directly by slight, successive modifications of a precursor system, because any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional . . . Since natural selection can only choose systems that are already working, then if a biological system cannot be produced gradually it would have to arise as an integrated unit, in one fell swoop, for natural selection to have anything to act on. P-647 at 39; P-718 at 694.
Professor Behe admitted in “Reply to My Critics” that there was a defect in his view of irreducible complexity because, while it purports to be a challenge to natural selection, it does not actually address “the task facing natural selection.” (P-718 at 695). Professor Behe specifically explained that “[t]he current definition puts the focus on removing a part from an already functioning system,” but “[t]he difficult task facing Darwinian evolution, however, would not be to remove parts from sophisticated pre-existing systems; it would be to bring together components to make a new system in the first place.” Id. In that article, Professor Behe wrote that he hoped to “repair this defect in future work;”
Page 74 of 139
however, he has failed to do so even four years after elucidating his defect. Id.; 22:61-65 (Behe).
In addition to Professor Behe’s admitted failure to properly address the very phenomenon that irreducible complexity purports to place at issue, natural selection, Drs. Miller and Padian testified that Professor Behe’s concept of irreducible complexity depends on ignoring ways in which evolution is known to occur. Although Professor Behe is adamant in his definition of irreducible complexity when he says a precursor “missing a part is by definition nonfunctional,” what he obviously means is that it will not function in the same way the system functions when all the parts are present. For example in the case of the bacterial flagellum, removal of a part may prevent it from acting as a rotary motor. However, Professor Behe excludes, by definition, the possibility that a precursor to the bacterial flagellum functioned not as a rotary motor, but in some other way, for example as a secretory system. (19:88-95 (Behe)).
As expert testimony revealed, the qualification on what is meant by “irreducible complexity” renders it meaningless as a criticism of evolution. (3:40 (Miller)). In fact, the theory of evolution proffers exaptation as a well-recognized, well-documented explanation for how systems with multiple parts could have evolved through natural means. Exaptation means that some precursor of the
Page 75 of 139
subject system had a different, selectable function before experiencing the change or addition that resulted in the subject system with its present function (16:146-48 (Padian)). For instance, Dr. Padian identified the evolution of the mammalian middle ear bones from what had been jawbones as an example of this process. (17:6-17 (Padian)). By defining irreducible complexity in the way that he has, Professor Behe attempts to exclude the phenomenon of exaptation by definitional fiat, ignoring as he does so abundant evidence which refutes his argument. Notably, the NAS has rejected Professor Behe’s claim for irreducible complexity by using the following cogent reasoning:
- [S]tructures and processes that are claimed to be ‘irreducibly’ complex typically are not on closer inspection. For example, it is incorrect to assume that a complex structure or biochemical process can function only if all its components are present and functioning as we see them today. Complex biochemical systems can be built up from simpler systems through natural selection. Thus, the ‘history’ of a protein can be traced through simpler organisms . . . The evolution of complex molecular systems can occur in several ways. Natural selection can bring together parts of a system for one function at one time and then, at a later time, recombine those parts with other systems of components to produce a system that has a different function. Genes can be duplicated, altered, and then amplified through natural selection. The complex biochemical cascade resulting in blood clotting has been explained in this fashion. P-192 at 22.
Page 76 of 139
As irreducible complexity is only a negative argument against evolution, it is refutable and accordingly testable, unlike ID, by showing that there are intermediate structures with selectable functions that could have evolved into the allegedly irreducibly complex systems. (2:15-16 (Miller)). Importantly, however, the fact that the negative argument of irreducible complexity is testable does not make testable the argument for ID. (2:15 (Miller); 5:39 (Pennock)). Professor Behe has applied the concept of irreducible complexity to only a few select systems: (1) the bacterial flagellum; (2) the blood-clotting cascade; and (3) the immune system. Contrary to Professor Behe’s assertions with respect to these few biochemical systems among the myriad existing in nature, however, Dr. Miller presented evidence, based upon peer-reviewed studies, that they are not in fact irreducibly complex.
First, with regard to the bacterial flagellum, Dr. Miller pointed to peer-reviewed studies that identified a possible precursor to the bacterial flagellum, a subsystem that was fully functional, namely the Type-III Secretory System. (2:8- 20 (Miller); P-854.23-854.32). Moreover, defense expert Professor Minnich admitted that there is serious scientific research on the question of whether the bacterial flagellum evolved into the Type-III Secretory System, the Type-III Secretory System into the bacterial flagellum, or whether they both evolved from a
Page 77 of 139
common ancestor. (38:12-16 (Minnich)). None of this research or thinking involves ID. (38:12-16 (Minnich)). In fact, Professor Minnich testified about his research as follows: “we’re looking at the function of these systems and how they could have been derived one from the other. And it’s a legitimate scientific inquiry.” (38:16 (Minnich)).
Second, with regard to the blood-clotting cascade, Dr. Miller demonstrated that the alleged irreducible complexity of the blood-clotting cascade has been disproven by peer-reviewed studies dating back to 1969, which show that dolphins’ and whales’ blood clots despite missing a part of the cascade, a study that was confirmed by molecular testing in 1998. (1:122-29 (Miller); P-854.17- 854.22). Additionally and more recently, scientists published studies showing that in puffer fish, blood clots despite the cascade missing not only one, but three parts. (1:128-29 (Miller)). Accordingly, scientists in peer-reviewed publications have refuted Professor Behe’s predication about the alleged irreducible complexity of the blood-clotting cascade. Moreover, cross-examination revealed that Professor Behe’s redefinition of the blood-clotting system was likely designed to avoid peerreviewed scientific evidence that falsifies his argument, as it was not a scientifically warranted redefinition. (20:26-28, 22:112-25 (Behe)). The immune system is the third system to which Professor Behe has applied
Page 78 of 139
the definition of irreducible complexity. Although in Darwin’s Black Box, Professor Behe wrote that not only were there no natural explanations for the immune system at the time, but that natural explanations were impossible regarding its origin. (P-647 at 139; 2:26-27 (Miller)). However, Dr. Miller presented peer-reviewed studies refuting Professor Behe’s claim that the immune system was irreducibly complex. Between 1996 and 2002, various studies confirmed each element of the evolutionary hypothesis explaining the origin of the immune system. (2:31 (Miller)). In fact, on cross-examination, Professor Behe was questioned concerning his 1996 claim that science would never find an evolutionary explanation for the immune system. He was presented with fifty-eight peer-reviewed publications, nine books, and several immunology textbook chapters about the evolution of the immune system; however, he simply insisted that this was still not sufficient evidence of evolution, and that it was not “good enough.” (23:19 (Behe)).
We find that such evidence demonstrates that the ID argument is dependent upon setting a scientifically unreasonable burden of proof for the theory of evolution. As a further example, the test for ID proposed by both Professors Behe and Minnich is to grow the bacterial flagellum in the laboratory; however, no-one inside or outside of the IDM, including those who propose the test, has conducted
Page 79 of 139
it. (P-718; 18:125-27 (Behe); 22:102-06 (Behe)). Professor Behe conceded that the proposed test could not approximate real world conditions and even if it could, Professor Minnich admitted that it would merely be a test of evolution, not design. (22:107-10 (Behe); 2:15 (Miller); 38:82 (Minnich)). We therefore find that Professor Behe’s claim for irreducible complexity has been refuted in peer-reviewed research papers and has been rejected by the scientific community at large. (17:45-46 (Padian); 3:99 (Miller)). Additionally, even if irreducible complexity had not been rejected, it still does not support ID as it is merely a test for evolution, not design. (2:15, 2:35-40 (Miller); 28:63-66 (Fuller)).
We will now consider the purportedly “positive argument” for design encompassed in the phrase used numerous times by Professors Behe and Minnich throughout their expert testimony, which is the “purposeful arrangement of parts.” Professor Behe summarized the argument as follows: We infer design when we see parts that appear to be arranged for a purpose. The strength of the inference is quantitative; the more parts that are arranged, the more intricately they interact, the stronger is our confidence in design. The appearance of design in aspects of biology is overwhelming. Since nothing other than an intelligent cause has been demonstrated to be able to yield such a strong appearance of design, Darwinian
Page 80 of 139
claims notwithstanding, the conclusion that the design seen in life is real design is rationally justified. (18:90-91, 18:109-10 (Behe); 37:50 (Minnich)). As previously indicated, this argument is merely a restatement of the Reverend William Paley’s argument applied at the cell level. Minnich, Behe, and Paley reach the same conclusion, that complex organisms must have been designed using the same reasoning, except that Professors Behe and Minnich refuse to identify the designer, whereas Paley inferred from the presence of design that it was God. (1:6- 7 (Miller); 38:44, 57 (Minnich)). Expert testimony revealed that this inductive argument is not scientific and as admitted by Professor Behe, can never be ruled out. (2:40 (Miller); 22:101 (Behe); 3:99 (Miller)).
Indeed, the assertion that design of biological systems can be inferred from the “purposeful arrangement of parts” is based upon an analogy to human design. Because we are able to recognize design of artifacts and objects, according to Professor Behe, that same reasoning can be employed to determine biological design. (18:116-17, 23:50 (Behe)). Professor Behe testified that the strength of the analogy depends upon the degree of similarity entailed in the two propositions; however, if this is the test, ID completely fails. Unlike biological systems, human artifacts do not live and reproduce over time. They are non-replicable, they do not undergo genetic recombination, and
Page 81 of 139
they are not driven by natural selection. (1:131-33 (Miller); 23:57-59 (Behe)). For human artifacts, we know the designer’s identity, human, and the mechanism of design, as we have experience based upon empirical evidence that humans can make such things, as well as many other attributes including the designer’s abilities, needs, and desires. (D-251 at 176; 1:131-33 (Miller); 23:63 (Behe); 5:55- 58 (Pennock)). With ID, proponents assert that they refuse to propose hypotheses on the designer’s identity, do not propose a mechanism, and the designer, he/she/it/they, has never been seen. In that vein, defense expert Professor Minnich agreed that in the case of human artifacts and objects, we know the identity and capacities of the human designer, but we do not know any of those attributes for the designer of biological life. (38:44-47 (Minnich)). In addition, Professor Behe agreed that for the design of human artifacts, we know the designer and its attributes and we have a baseline for human design that does not exist for design of biological systems. (23:61-73 (Behe)). Professor Behe’s only response to these seemingly insurmountable points of disanalogy was that the inference still works in science fiction movies. (23:73 (Behe)).
It is readily apparent to the Court that the only attribute of design that biological systems appear to share with human artifacts is their complex appearance, i.e. if it looks complex or designed, it must have been designed.
Page 82 of 139
(23:73 (Behe)). This inference to design based upon the appearance of a “purposeful arrangement of parts” is a completely subjective proposition, determined in the eye of each beholder and his/her viewpoint concerning the complexity of a system. Although both Professors Behe and Minnich assert that there is a quantitative aspect to the inference, on cross-examination they admitted that there is no quantitative criteria for determining the degree of complexity or number of parts that bespeak design, rather than a natural process. (23:50 (Behe); 38:59 (Minnich)). As Plaintiffs aptly submit to the Court, throughout the entire trial only one piece of evidence generated by Defendants addressed the strength of the ID inference: the argument is less plausible to those for whom God’s existence is in question, and is much less plausible for those who deny God’s existence. (P- 718 at 705).
Accordingly, the purported positive argument for ID does not satisfy the ground rules of science which require testable hypotheses based upon natural explanations. (3:101-03 (Miller)). ID is reliant upon forces acting outside of the natural world, forces that we cannot see, replicate, control or test, which have produced changes in this world. While we take no position on whether such forces exist, they are simply not testable by scientific means and therefore cannot qualify as part of the scientific process or as a scientific theory. (3:101-02 (Miller)).
Page 83 of 139
It is appropriate at this juncture to address ID’s claims against evolution. ID proponents support their assertion that evolutionary theory cannot account for life’s complexity by pointing to real gaps in scientific knowledge, which indisputably exist in all scientific theories, but also by misrepresenting well established scientific propositions. (1:112, 1:122, 1:136-37 (Miller); 16:74-79, 17:45-46 (Padian)).
Before discussing Defendants’ claims about evolution, we initially note that an overwhelming number of scientists, as reflected by every scientific association that has spoken on the matter, have rejected the ID proponents’ challenge to evolution. Moreover, Plaintiffs’ expert in biology, Dr. Miller, a widely-recognized biology professor at Brown University who has written university-level and highschool biology textbooks used prominently throughout the nation, provided unrebutted testimony that evolution, including common descent and natural selection, is “overwhelmingly accepted” by the scientific community and that every major scientific association agrees. (1:94-100 (Miller)). As the court in Selman explained, “evolution is more than a theory of origin in the context of science. To the contrary, evolution is the dominant scientific theory of origin accepted by the majority of scientists.” Selman, 390 F. Supp. 2d at 1309 (emphasis in original). Despite the scientific community’s overwhelming support for
Page 84 of 139
evolution, Defendants and ID proponents insist that evolution is unsupported by empirical evidence. Plaintiffs’ science experts, Drs. Miller and Padian, clearly explained how ID proponents generally and Pandas specifically, distort and misrepresent scientific knowledge in making their anti-evolution argument. In analyzing such distortion, we turn again to Pandas, the book to which students are expressly referred in the disclaimer. Defendants hold out Pandas as representative of ID and Plaintiffs’ experts agree in that regard. (16:83 (Padian); 1:107-08 (Miller)). A series of arguments against evolutionary theory found in Pandas involve paleontology, which studies the life of the past and the fossil record. Plaintiffs’ expert Professor Padian was the only testifying expert witness with any expertise in paleontology.15 His testimony therefore remains unrebutted. Dr. Padian’s demonstrative slides, prepared on the basis of peer-reviewing scientific literature, illustrate how Pandas systematically distorts and misrepresents established, important evolutionary principles. We will provide several representative examples of this distortion. First, Pandas misrepresents the “dominant form of understanding relationships” between
- 15 Moreover, the Court has been presented with no evidence that either Defendants’ testifying experts or any other ID proponents, including Pandas’ authors, have such paleontology expertise as we have been presented with no evidence that they have published peer-reviewed literature or presented such information at scientific conferences on paleontology or the fossil record. (17:15-16 (Padian)).

organisms, namely, the tree of life, represented by classification determined via the method of cladistics. (16:87-97 (Padian); P-855.6-855.19). Second, Pandas misrepresents “homology,” the “central concept of comparative biology,” that allowed scientists to evaluate comparable parts among organisms for classification purposes for hundreds of years. (17:27-40 (Padian); P-855.83-855.102). Third, Pandas fails to address the well-established biological concept of exaptation, which involves a structure changing function, such as fish fins evolving fingers and bones to become legs for weight-bearing land animals. (16:146-48 (Padian)). Dr. Padian testified that ID proponents fail to address exaptation because they deny that organisms change function, which is a view necessary to support abruptappearance. Id. Finally, Dr. Padian’s unrebutted testimony demonstrates that Pandas distorts and misrepresents evidence in the fossil record about pre- Cambrian-era fossils, the evolution of fish to amphibians, the evolution of small carnivorous dinosaurs into birds, the evolution of the mammalian middle ear, and the evolution of whales from land animals. (16:107-17, 16:117-31, 16:131-45, 17:6-9, 17:17-27 (Padian); P-855.25-855.33, P-855.34-855.45, P-855.46-855.55, P-855.56-866.63, P-855.64-855.82). In addition to Dr. Padian, Dr. Miller also testified that Pandas presents discredited science. Dr. Miller testified that Pandas’ treatment of biochemical

similarities between organisms is “inaccurate and downright false” and explained how Pandas misrepresents basic molecular biology concepts to advance design theory through a series of demonstrative slides. (1:112 (Miller)). Consider, for example, that he testified as to how Pandas misinforms readers on the standard evolutionary relationships between different types of animals, a distortion which Professor Behe, a “critical reviewer” of Pandas who wrote a section within the book, affirmed. (1:113-17 (Miller); P-854.9-854.16; 23:35-36 (Behe)).16 In addition, Dr. Miller refuted Pandas’ claim that evolution cannot account for new genetic information and pointed to more than three dozen peer-reviewed scientific publications showing the origin of new genetic information by evolutionary processes. (1:133-36 (Miller); P-245). In summary, Dr. Miller testified that Pandas misrepresents molecular biology and genetic principles, as well as the current state of scientific knowledge in those areas in order to teach readers that common descent and natural selection are not scientifically sound. (1:139-42 (Miller)).
Accordingly, the one textbook to which the Dover ID Policy directs students contains outdated concepts and badly flawed science, as recognized by even the
- 16 Additionally, testimony provided by Professor Behe revealed an increasing gap between his portrayal of ID theory and how it is presented in Pandas. Although he is a “critical reviewer” of the work, he disagrees with language provided in the text, including but not limited to the text’s very definition of ID. (P-11 at 99-100).

defense experts in this case.
A final indicator of how ID has failed to demonstrate scientific warrant is the complete absence of peer-reviewed publications supporting the theory. Expert testimony revealed that the peer review process is “exquisitely important” in the scientific process. It is a way for scientists to write up their empirical research and to share the work with fellow experts in the field, opening up the hypotheses to study, testing, and criticism. (1:66-69 (Miller)). In fact, defense expert Professor Behe recognizes the importance of the peer review process and has written that science must “publish or perish.” (22:19-25 (Behe)). Peer review helps to ensure that research papers are scientifically accurately, meet the standards of the scientific method, and are relevant to other scientists in the field. (1:39-40 (Miller)). Moreover, peer review involves scientists submitting a manuscript to a scientific journal in the field, journal editors soliciting critical reviews from other experts in the field and deciding whether the scientist has followed proper research procedures, employed up-to-date methods, considered and cited relevant literature and generally, whether the researcher has employed sound science. The evidence presented in this case demonstrates that ID is not supported by any peer-reviewed research, data or publications. Both Drs. Padian and Forrest testified that recent literature reviews of scientific and medical-electronic databases
Page 88 of 139
disclosed no studies supporting a biological concept of ID. (17:42-43 (Padian); 11:32-33 (Forrest)). On cross-examination, Professor Behe admitted that: “There are no peer reviewed articles by anyone advocating for intelligent design supported by pertinent experiments or calculations which provide detailed rigorous accounts of how intelligent design of any biological system occurred.” (22:22-23 (Behe)). Additionally, Professor Behe conceded that there are no peer-reviewed papers supporting his claims that complex molecular systems, like the bacterial flagellum, the blood-clotting cascade, and the immune system, were intelligently designed. (21:61-62 (complex molecular systems), 23:4-5 (immune system), and 22:124-25 (blood-clotting cascade) (Behe)). In that regard, there are no peer-reviewed articles supporting Professor Behe’s argument that certain complex molecular structures are “irreducibly complex.”17 (21:62, 22:124-25 (Behe)). In addition to failing to produce papers in peer-reviewed journals, ID also features no scientific research or testing. (28:114-15 (Fuller); 18:22-23, 105-06 (Behe)). After this searching and careful review of ID as espoused by its proponents,
- 17 The one article referenced by both Professors Behe and Minnich as supporting ID is an article written by Behe and Snoke entitled “Simulating evolution by gene duplication of protein features that require multiple amino acid residues.” (P-721). A review of the article indicates that it does not mention either irreducible complexity or ID. In fact, Professor Behe admitted that the study which forms the basis for the article did not rule out many known evolutionary mechanisms and that the research actually might support evolutionary pathways if a biologically realistic population size were used. (22:41-45 (Behe); P-756).

as elaborated upon in submissions to the Court, and as scrutinized over a six week trial, we find that ID is not science and cannot be adjudged a valid, accepted scientific theory as it has failed to publish in peer-reviewed journals, engage in research and testing, and gain acceptance in the scientific community. ID, as noted, is grounded in theology, not science. Accepting for the sake of argument its proponents’, as well as Defendants’ argument that to introduce ID to students will encourage critical thinking, it still has utterly no place in a science curriculum. Moreover, ID’s backers have sought to avoid the scientific scrutiny which we have now determined that it cannot withstand by advocating that the controversy, but not ID itself, should be taught in science class. This tactic is at best disingenuous, and at worst a canard. The goal of the IDM is not to encourage critical thought, but to foment a revolution which would supplant evolutionary theory with ID.
To conclude and reiterate, we express no opinion on the ultimate veracity of ID as a supernatural explanation. However, we commend to the attention of those who are inclined to superficially consider ID to be a true “scientific” alternative to evolution without a true understanding of the concept the foregoing detailed analysis. It is our view that a reasonable, objective observer would, after reviewing both the voluminous record in this case, and our narrative, reach the inescapable conclusion that ID is an interesting theological argument, but that it is not science.
