The level of support for evolution among scientists, the public and other groups is a topic that frequently arises in the creation-evolution controversy and touches on educational, religious, philosophical, scientific and political issues. The subject is primarily contentious in the United States. However, it is also important in other countries where creationists advocate the teaching of creationism as a valid alternative to evolution, or portray the modern evolutionary synthesis as an inadequate scientific paradigm.
While an overwhelming majority of the scientific community accepts evolution as the dominant scientific theory of biological origin,[1][2] creationists have asserted that there is a significant scientific controversy and disagreement over the validity of evolution.[3][4][5]
The Discovery Institute, a pro-intelligent design lobby group located in the United States, also claims that because there is a significant lack of public support for evolution, that public schools should, as their campaign states, "Teach the Controversy". Nearly every scientific society, representing hundreds of thousands of scientists, has issued official statements disputing this claim[2] and a petition supporting the teaching of evolutionary biology was endorsed by 72 US Nobel Prize winners.[6] Additionally, US courts have ruled in favor of teaching evolution in science classrooms, and against teaching creationism, in numerous cases such as Edwards v. Aguillard, Hendren v. Campbell, McLean v. Arkansas and Kitzmiller v. Dover Area School District.
Creationists have had some successes in the political realm in the US and other countries.[7][8][9][10][11][12] There is widespread belief in creationism in the Muslim world,[13] South Africa, India,[14] South Korea and Brazil, with smaller followings in Israel,[15] Australia,[16] New Zealand,[17] and Canada.[18] The most prominent organization behind this movement has been the Discovery Institute, the driving force behind the intelligent design movement. Through its Center for Science and Culture, the Institute conducts a number of related public relations and lobbying campaigns aimed at influencing the public and policy makers in order to advance its position in academia, which it claims is dogmatic and hidebound.
Many claims in the creation-evolution controversy rest on whether or not evolution is genuinely disputed by those in scientific circles, the public's acceptance of the theory of evolution and religious and educational organizations and both sides of the dispute exhibit interest in evaluating the level of popular and scientific support for evolution. Several publications discuss the subject,[19][20] including a document produced by the United States National Academy of Sciences.[21]

The vast majority of the scientific community and academia supports evolutionary theory as the only explanation that can fully account for observations in the fields of biology, paleontology, molecular biology, genetics, anthropology, and others.[22][23][24][25][26] One 1987 estimate found that "700 scientists ... (out of a total of 480,000 U.S. earth and life scientists) ... give credence to creation-science".[27] An expert in the evolution-creationism controversy, professor and author Brian Alters, states that "99.9 percent of scientists accept evolution".[28] A 1991 Gallup poll of Americans found that about 5% of scientists (including those with training outside biology) identified themselves as creationists.[29][30]
Additionally, the scientific community considers intelligent design, a neo-creationist offshoot, to be unscientific,[31] pseudoscience,[32][33] or junk science.[34][35] The U.S. National Academy of Sciences has stated that intelligent design "and other claims of supernatural intervention in the origin of life" are not science because they cannot be tested by experiment, do not generate any predictions, and propose no new hypotheses of their own.[36] In September 2005, 38 Nobel laureates issued a statement saying "Intelligent design is fundamentally unscientific; it cannot be tested as scientific theory because its central conclusion is based on belief in the intervention of a supernatural agent."[37] In October 2005, a coalition representing more than 70,000 Australian scientists and science teachers issued a statement saying "intelligent design is not science" and calling on "all schools not to teach Intelligent Design (ID) as science, because it fails to qualify on every count as a scientific theory".[38]
In 1986, an amicus curiae brief, signed by 72 US Nobel Prize winners, 17 state academies of science and 7 other scientific societies, asked the US Supreme Court in Edwards v. Aguillard, to reject a Louisiana state law requiring the teaching of creationism (which the brief described as embodying religious dogma).[6] This was the largest collection of Nobel Prize winners to sign anything up to that point, providing the "clearest statement by scientists in support of evolution yet produced."[26]
There are many scientific and scholarly organizations from around the world that have issued statements in support of the theory of evolution.[39][40][41][42] The American Association for the Advancement of Science, the world's largest general scientific society with more than 130,000 members and over 262 affiliated societies and academies of science including over 10 million individuals, has made several statements and issued several press releases in support of evolution.[25] The prestigious United States National Academy of Sciences, which provides science advice to the nation, has published several books supporting evolution and denouncing creationism and intelligent design.[43][44]
There is a notable difference between the opinion of scientists and that of the general public in the United States. A 2009 poll by Pew Research Center found that "Nearly all scientists (97%) say humans and other living things have evolved over time – 87% say evolution is due to natural processes, such as natural selection. The dominant position among scientists – that living things have evolved due to natural processes – is shared by only about third (32%) of the public."[45]
One of the earliest resolutions in support of evolution was issued by the American Association for the Advancement of Science in 1922, and readopted in 1929.[46][47]
Another early effort to express support for evolution by scientists was organized by Nobel Prize Winner German biologist Hermann J. Muller in 1966. Muller circulated a petition entitled "Is Biological Evolution a Principle of Nature that has been well established by Science?" in May 1966:
There are no hypotheses, alternative to the principle of evolution with its “tree of life,” that any competent biologist of today takes seriously. Moreover, the principle is so important for an understanding of the world we live in and of ourselves that the public in general, including students taking biology in high school, should be made aware of it, and of the fact that it is firmly established, even as the rotundity of the earth is firmly established.[48]
This manifesto was signed by 177 of the leading American biologists, including George G. Simpson of Harvard University, Nobel Prize Winner Peter Agre of Duke University, Carl Sagan of Cornell, John Tyler Bonner of Princeton, Nobel Prize Winner George Beadle, President of the University of Chicago, and Donald F. Kennedy of Stanford University, formerly head of the United States Food and Drug Administration.[49]
This was followed by the passing of a resolution by the American Association for the Advancement of Science (AAAS) in the fall of 1972 that stated, in part, "the theory of creation ... is neither scientifically grounded nor capable of performing the rules required of science theories".[50] The United States National Academy of Sciences also passed a similar resolution in the fall of 1972.[50] A statement on evolution called "A Statement Affirming Evolution as a Principle of Science." was signed by Nobel Prize Winner Linus Pauling, Isaac Asimov, George G. Simpson, Caltech Biology Professor Norman H. Horowitz, Ernst Mayr, and others, and published in 1977.[51] The governing board of the American Geological Institute issued a statement supporting resolution in November 1981.[52] Shortly thereafter, the AAAS passed another resolution supporting evolution and disparaging efforts to teach creationism in science classes.[53]
Creationists strongly dispute the fact that there is overwhelming support for evolution in the science community.[54] One of the first attempts to provide evidence that there were substantial number of scientists who disagreed with evolution was a pamphlet produced by the Institute for Creation Research in 1971 entitled "21 Scientists Who Believe in Creation"[55] This pamphlet has been reprinted several times. Skeptics have claimed that this list of 21 creation supporters is misleading since it includes five people with PhDs in engineering, three in education, two in theology, two in biochemistry, one in physics, one in chemistry, one in hydrology, one in entomology, one in psycholinguistics, one in food science technology, one in ecology, one in physiology and one in geophysics; and therefore only a small minority had qualifications related to evolutionary biology.[56][57]
Similarly, chemist John F. Ashton edited a book first published in 1999 with essays from 50 scientists describing why they believed in creationism.[58] Ann Lamont wrote a book describing 21 famous scientists, such as Johannes Kepler, Robert Boyle, Isaac Newton, Carolus Linnaeus, Leonhard Euler, Michael Faraday, Charles Babbage, James Prescott Joule, Louis Pasteur, Kelvin, James Clerk Maxwell, and Wernher von Braun, who she claimed believed in biblical literalism.[59] However, many of these scientists lived before much of the evidence against biblical literalism emerged. Of the previous list, only aerospace engineer Wernher von Braun was alive when evolution was firmly established and the geological evidence against Noah's Ark had clearly emerged. Also, of the scientists listed above, only Linnaeus and Pasteur were trained in and worked in a field relevant to biology.
In continuing attempts to counter the charge that there are extremely few scientists who disagree with the principles of evolution, creationist organizations have gathered lists of hundreds of scientists who disagree with evolution and support creationism. Some prominent creationist organizations that have produced these kinds of lists include the Discovery Institute's "A Scientific Dissent From Darwinism",[60] the Institute for Creation Research,[61] Answers in Genesis,[62] Creation Ministries International.[63] and Christian Answers.[64] The Institute for Creation Research website includes the following statement:
Today there are thousands of scientists who are creationists and who repudiate any form of evolution in their analysis and use of scientific data. Creationist scientists can now be found in literally every discipline of science and their numbers are increasing rapidly. In the Creation Research Society (2717 Cranbrook Rd., Ann Arbor, MI 48104) alone there are over 650 scientist members with either doctor's or master's degrees in some field of natural science. Among the additional 2,000 + sustaining members of the Society, many are also scientists with bachelor's degrees, in addition to numerous social scientists and other highly educated people with postgraduate degrees in their own fields. Evolutionists are finding it increasingly difficult to maintain the fiction that evolution is "science" and creation is "religion." When news media personnel and others make such statements today, they merely reveal their own liberal social philosophies—not their awareness of scientific facts![3]
To date however, there are no scientifically peer-reviewed research articles that disclaim evolution listed in the scientific and medical journal search engine Pubmed.[65]
The Discovery Institute announced that over 700 scientists had expressed support for intelligent design as of February 8, 2007.[66][67] This prompted the National Center for Science Education to produce a "light-hearted" petition called "Project Steve" in support of evolution. Only scientists named "Steve" or some variation (such as Stephen, Stephanie, and Stefan) are eligible to sign the petition. It is intended to be a "tongue-in-cheek parody" of the lists of alleged "scientists" supposedly supporting creationist principles that creationist organizations produce.[68][69] The petition demonstrates that there are more scientists who accept evolution with a name like "Steve" alone (over 1100[70]) than there are in total who support intelligent design. This is, again, why the percentage of scientists who support evolution has been estimated by Brian Alters to be about 99.9 percent.[28] The organization "Physicians and Surgeons for Scientific Integrity" maintains a list of medical doctors and similar professionals who disagree that evolution can account for the diversity of life on earth. As of May 22, 2007, there were 224 Americans and 28 others from other countries that had signed a statement disputing "Darwinism".
Many creationists act as evangelists and their organizations are registered as tax-free religious organizations.[72] Creationists have claimed that they represent the interests of true Christians, and evolution is only associated with atheism.[73][74][75]
However, not all religious organizations find support for evolution incompatible with their religious faith. For example, 12 of the plaintiffs opposing the teaching of creation science in the influential McLean v. Arkansas court case were clergy representing Methodist, Episcopal, African Methodist Episcopal, Catholic, Southern Baptist, Reform Jewish, and Presbyterian groups.[76] There are several religious organizations that have issued statements advocating the teaching of evolution in public schools.[77] In addition, the Archbishop of Canterbury, Dr. Rowan Williams, issued statements in support of evolution in 2006.[78] The Clergy Letter Project is a signed statement by 11,111 (as of 22 December 2007) American Christian clergy of different denominations rejecting creationism organized in 2004. Molleen Matsumura of the National Center for Science Education found, of Americans in the twelve largest Christian denominations, at least 77% belong to churches that support evolution education (and that at one point, this figure was as high as 89.6%).[79] These religious groups include the Catholic Church, as well as various denominations of Protestantism, including the United Methodist Church, National Baptist Convention, USA, Evangelical Lutheran Church in America, Presbyterian Church (USA), National Baptist Convention of America, African Methodist Episcopal Church, the Episcopal Church, and others.[80][81] A figure closer to about 71% is presented by the analysis of Walter B. Murfin and David F. Beck.[82]
Michael Shermer argued in Scientific American in October 2006 that evolution supports concepts like family values, avoiding lies, fidelity, moral codes and the rule of law. Shermer also suggests that evolution gives more support to the notion of an omnipotent creator, rather than a tinkerer with limitations based on a human model.[83]
The Ahmadiyya Movement are one of the few denominations in Islam that universally accept Evolution and actively promote it.[84] Mirza Tahir Ahmad, Fourth Caliph of the Ahmadiyya Muslim Community has stated in his magnum opus Revelation, Rationality, Knowledge & Truth that evolution did occur but only through God being the One who brings it about. It does not occur itself, according to the Ahmadiyya Muslim Community. The Ahmadis do not believe in Adam as the first human on earth but merely as the first prophet to receive revelation by God on earth.
A fundamental part of `Abdul-Bahá's teachings on evolution is the belief that all life came from the same origin: "the origin of all material life is one..."[85] He states that from this sole origin, the complete diversity of life was generated: "Consider the world of created beings, how varied and diverse they are in species, yet with one sole origin"[86] He explains that a slow, gradual process led to the development of complex entities:
Evolutionary theory can be seen in a way which is compatible with Catholic dogma, according to the Church. On the 12 August 1950, the Catholic Church accepted that the theory of evolution was a valid scientific inquiry, stated by Pope Pius XII in the encyclical Humani Generis saying “research and discussions… take place with regard to the doctrine of evolution”. In the same encyclical the Magisterium holds that a Catholic can believe in the creation account found in sacred scripture. However, the encyclical rejects what it described as “fictitious tenets of evolution”, such as “Some imprudently and indiscreetly hold that evolution, which has not been fully proved even in the domain of natural sciences, explains the origin of all this, and audaciously support the monistic and pantheistic opinion that the world is in continual evolution.”.[88]
In 1996 Pope John Paul II gave a message to the Pontifical Academy of Sciences in which he said “Today, almost half a century after publication of the encyclical, new knowledge has led to the recognition of the theory of evolution as more than a hypothesis.”[89]
Between 2000 and 2002 the International Theological Commission found that “Converging evidence from many studies in the physical and biological sciences furnishes mounting support for some theory of evolution to account for the development and diversification of life on earth, while controversy continues over the pace and mechanisms of evolution.”[90] This statement was published by the Vatican on July 2004 by the authority of Cardinal Ratzinger (now Pope Benedict XVI) who was the President of the Commission at the time.
The Magisterium has not yet made an authoritative statement on intelligent design, and has permitted arguments on both sides of the issue. In 2005, Cardinal Christoph Schönborn of Vienna appeared to endorse intelligent design when he denounced philosophically materialist interpretations of evolution.[91] In an op-ed in the New York Times he said "Evolution in the sense of common ancestry might be true, but evolution in the neo-Darwinian sense - an unguided, unplanned process of random variation and natural selection - is not."[92]
In the January 16–17 2006 edition of the official Vatican newspaper L'Osservatore Romano, University of Bologna evolutionary biology Professor Fiorenzo Facchini wrote an article agreeing with the judge's ruling in Kitzmiller v. Dover and stating that intelligent design was unscientific.[93][94] Jesuit Father George Coyne, former director of the Vatican Observatory, has also denounced intelligent design.[95]
Hindus believe in the concept of evolution of life on Earth[96] The concepts of Dashavatara- different incarnations of God starting from simple organisms and progressively becoming complex beings and that of Day and Night of Brahma are generally spotted as instances of Hindu acceptance of Evolution.
On the other hand, in the U.S., many Protestant denominations promote creationism, preach against evolution from the pulpits, and sponsor lectures and debates on the subject. A list of denominations that explicitly advocate creationism instead of what they call "Darwinism" or evolution include the Assemblies of God,[97] the Evangelical Presbyterian Church,[98] the Free Methodist Church, Jehovah's Witnesses, Lutheran Church - Missouri Synod,[99] Pentecostal Churches, Seventh-day Adventist Churches,[100] Wisconsin Evangelical Lutheran Synod, Christian Reformed Church, Southern Baptist Convention,[101] and the Pentecostal Oneness churches.[102]
A common complaint of creationists is that evolution is of no value, has never been used for anything, and will never be of any use. According to many creationists, nothing would be lost by getting rid of evolution, and science and industry might even benefit.[103][104][105]
In fact, evolution is being put to practical use in industry and widely used on a daily basis by researchers in medicine, biochemistry, molecular biology, and genetics to both formulate hypotheses about biological systems for the purposes of experimental design, as well as to rationalise observed data and prepare applications.[28][106][107][108] In 2009, there were 235,740 scientific papers in PubMed that mentioned 'evolution'. Corporations such as pharmaceutical companies utilize biological evolution in their development of new products.[107]
Because of the perceived value of evolution in applications, there have been some expressions of support for evolution on the part of corporations. In Kansas, there has been some widespread concern in the corporate and academic communities that a move to weaken the teaching of evolution in schools will hurt the state's ability to recruit the best talent, particularly in the biotech industry.[109] Paul Hanle of the Biotechnology Institute warned that the US risks falling behind in the biotechnology race with other nations if it does not do a better job of teaching evolution.[110] James McCarter of Divergence Incorporated states that the work of 2001 Nobel Prize winner Leland Hartwell which has substantial implications for combating cancer relied heavily on the use of evolutionary knowledge and predictions. McCarter points out that 47 of the last 50 Nobel Prizes in medicine or physiology also depended on the use of evolutionary theory.[111]
There are also many educational organizations that have issued statements in support of the theory of evolution.[112]
Repeatedly, creationists and intelligent design advocates have lost suits in US courts.[113] Here is a list of important court cases in which creationists have suffered setbacks:
In some countries, creationist beliefs (or a lack of support for evolutionary theory) are relatively widespread, even garnering a majority of public opinion. A study published in Science compared attitudes about evolution in the United States, 32 European countries (including Turkey) and Japan. The only country where acceptance of evolution was lower than in the United States was Turkey (25%). Public acceptance of evolution was most widespread (at over 80% of the population) in Iceland, Denmark and Sweden.[126]
In a 2010 poll, 59% of respondents said they believe in theistic evolution, or evolution guided by God. A further 8% believe in evolution without divine intervention, while 25% were creationists. Support for creationism was stronger among the poor and the least educated.[127]
59% of Canadians believe that humans evolved from less advanced life forms, but 42% agree that humans and dinosaurs co-existed on earth. Only 22% believe that God created human beings in their present form within the last 10,000 years. [128]
A 2006 UK poll on the "origin and development of life" asked participants to choose between three different explanations for the origin of life: 22% chose (Young Earth) creationism, 17% opted for intelligent design, 48% selected evolution theory (with a divine role explicitly excluded) and the rest did not know. However, the poll lacked nuanced survey techniques and equivocated on origin definitions, forcing participants to choose between only these options (which notably excluded theistic evolution). Hence its results are not necessarily an accurate survey of the views of the UK public.[129][130]
| US Group | Young Earth Creationism | Belief in God-guided evolution | Belief in evolution without God |
|---|---|---|---|
| Public | 44% | 39% | 10% |
| Scientists | 5% | 40% | 55% |
The US has one of the highest levels of public belief in biblical or other religious accounts of the origins of life on earth among industrialized countries.[132]
According to a 2007 Gallup poll,[133] about 43% of American believe that "God created human beings pretty much in their present form at one time within the last 10,000 years or so." This is only slightly less than the 46% reported in a 2006 Gallup poll.[134] Only 14% believed that "humans being have developed over millions of years from less advanced forms of life, but God had no part in this process", despite 49% of respondents indicating they believed in evolution.[133] Belief in creationism is inversely correlated to education; only 22% of those with post-graduate degrees believe in strict creationism.[134] A 2000 poll for People for the American Way found 70% of the American public felt that evolution was compatible with a belief in God.[135]
| Political identification | % do not believe in evolution | % belief in evolution |
|---|---|---|
| Republican | 68 | 30 |
| Democrat | 40 | 57 |
| Independent | 37 | 61 |
| Political identification | % Creationist | % belief in evolution |
|---|---|---|
| Republican | 60 | 11 |
| Democrat | 29 | 44 |
A 2005 Pew Research Center poll found that 70% of evangelical Christians felt that living organisms have not changed since their creation, but only 31% of Catholics and 32% of mainline Protestants shared this opinion. A 2005 Harris Poll[138] estimated that 63% of liberals and 37% of conservatives agreed that humans and other primates have a common ancestry.[83]
A 2009 poll showed that almost a quarter of Australians believe "the biblical account of human origins" over the Darwinian account. 42 percent of Australians believe in a "wholly scientific" explanation for the origins of life, while 32 percent believe in an evolutionary process "guided by God".[139]
A 2010 survey conducted by Auspoll and the Australian Academy of Science found that 79% of Australians believe in evolution (71% believe it is currently occurring, 8% believe in evolution but do not think it is currently occurring), 11% were not sure and 10% stated they do not believe in evolution. [140]
A 1997 study found that fewer than 20% of Americans possessed basic scientific literacy[141] and a People for the American Way poll found that less than half (48%) of those polled chose the correct definition of evolution from a list.[135] In 2006, New Scientist reported that almost 2/3 of Americans believe they share less than half their genes with "monkeys", when in fact the figure is between 95–99% depending on the primate and comparison method.[142]
Steve Sailer has pointed out that it is not clear how firmly public beliefs in creationism are held.[143] Most creationist claims require a literal reading of Genesis and a belief in biblical inerrancy, while a 2006 study by the Baylor Institute for Studies of Religion found only a minority of those polled believed in the literal truth in the Bible.[144]
| Religious group | Belief in the literal truth of the Bible | Belief that the Bible is a book of history and legends |
| Evangelical Protestants | 47.8 | 6.5 |
| Catholics | 11.8 | 19.8 |
| Mainline Protestant | 11.2 | 22.0 |
| Jewish | 8.9 | 52.6 |
The level of assent that evolution garners has changed with time. The trends in acceptance of evolution can be estimated.
The level of support for evolution in different communities has varied with time. Darwin's theory had convinced almost every naturalist within 20 years of its publication in 1858, and was making serious inroads with the public and the more liberal clergy. It had reached such extremes, that by 1880, one American religious weekly publication estimated that "perhaps a quarter, perhaps a half of the educated ministers in our leading Evangelical denominations" felt "that the story of the creation and fall of man, told in Genesis, is no more the record of actual occurrences than is the parable of the Prodigal Son."[145]
By the late 19th century, many of the most conservative Christians accepted an ancient earth, and life on earth before Eden. Victorian Era Creationists were more akin to people who subscribe to theistic evolution today. Even fervent anti-evolutionist Scopes Trial prosecutor William Jennings Bryan interpreted the "days" of Genesis as ages of the earth, and acknowledged that biochemical evolution took place, drawing the line only at the story of Adam and Eve's creation. Prominent pre-World War II creationist Harry Rimmer allowed an Old Earth by slipping millions of years into putative gaps in the Genesis account, and claimed that the Noachian Flood was only a local phenomenon.[145]
In the decades of the 20th century, George Macready Price and a tiny group of Seventh-day Adventist followers were the among the very few believers in a Young Earth and a worldwide flood, which Price championed in his "new catastrophism" theories. It was not until the publication of John C. Whitcomb, Jr., and Henry M. Morris’s book Genesis Flood in 1961 that Price's idea was revived. In the last few decades, many creationists have adopted Price's beliefs, becoming progressively more strict biblical literalists.[145]
In a 1991 Gallup poll, 47% of the US population, and 25% of college graduates agreed with the statement, "God created man pretty much in his present form at one time within the last 10,000 years."
Fourteen years later, in 2005, Gallup found that 53% of Americans expressed the belief that "God created human beings in their present form exactly the way the Bible describes it." About 2/3 (65.5%) of those surveyed thought that creationism was definitely or probably true. In 2005 a Newsweek poll discovered that 80 percent of the American public thought that "God created the universe." and the Pew Research Center reported that "nearly two-thirds of Americans say that creationism should be taught alongside evolution in public schools." Ronald Numbers commented on that with "Most surprising of all was the discovery that large numbers of high-school biology teachers — from 30% in Illinois and 38% in Ohio to a whopping 69% in Kentucky — supported the teaching of creationism."[145]
The National Center for Science Education reports that from 1985 to 2005, the number of Americans unsure about evolution increased from 7% to 21%, while the number rejecting evolution declined from 48% to 39%.[126][142] Jon Miller of Michigan State University has found in his polls that the number of Americans who accept evolution has declined from 45% to 40% from 1985 to 2005.[146]
In light of these somewhat contradictory results, it is difficult to know for sure what is happening to public opinion on evolution in the US. It does not appear that either side is making unequivocal progress. It does appear that uncertainty about the issue is increasing, however.
Anecdotal evidence is that creationism is becoming more of an issue in the UK as well. One report in 2006 was that UK students are increasingly arriving ill-prepared to participate in medical studies or other advanced education.[147]
The level of support for creationism among relevant scientists is minimal. Only 700 out of 480,000 U.S. earth and life scientists gave credence to creationism in 1987,[27] representing about 0.146% of relevant scientists. In 2007 the Discovery Institute reported that about 600 scientists signed their A Scientific Dissent From Darwinism list, up from 100 in 2001.[148] The actual statement of the Scientific Dissent from Darwinism is a relatively mild one that expresses skepticism about the absoluteness of 'Darwinism' (and is in line with the falsifiability required of scientific theories) to explain all features of life, and does not in any way represent an absolute denial or rejection of evolution.[149] By contrast, a tongue-in-cheek response known as Project Steve, a list of scientists named Steve who agree that evolution is "a vital, well-supported, unifying principle of the biological sciences," has 1080 Steves as of March 26, 2009. People named Steve make up approximately 1% of the total U.S. population.
The United States National Science Foundation statistics on US yearly science graduates demonstrate that from 1987 to 2001, the number of biological science graduates increased by 59% while the number of geological science graduates decreased by 20.5%. However, the number of geology graduates in 2001 was only 5.4% of the number of graduates in the biological sciences, while it was 10.7% of the number of biological science graduates in 1987.[150] The Science Resources Statistics Division of the National Science Foundation estimated that in 1999, there were 955,300 biological scientists in the US (about 1/3 of who hold graduate degrees). There were also 152,800 earth scientists in the US as well.[151]
Therefore, the 600 Darwin Dissenters signing the A Scientific Dissent From Darwinism represent about 0.054% of the estimated 1,108,100 biological and geological scientists in the US in 1999. In addition, a large fraction of the Darwin Dissenters have specialties unrelated to research on evolution; of the dissenters, three-quarters are not biologists.[152] Therefore, the roughly 150 biologist Darwin Dissenters represent about 0.0157% of the US biologists that existed in 1999. As of 2006, the list was expanded to include non-US scientists, overestimating the number of US scientists that do not accept evolution according to the Discovery Institute,[153] a known creationist lobby institution. Despite the increase in absolute number of scientists willing to sign the dissent form, and an increase in public support, proportionately the figures indicates the support from scientists for creationism and intelligent design is steadily decreasing.
