Statement of the National Science Teachers Association in Response to the Kansas State Board of Education's Actions to Remove Evolution from State Standards

Graphic Rule 

Arlington, Virginia, August 13, 1999 -- The Kansas State Board of Education's 6 to 4 vote to remove the teaching of evolution from the state standards does a disservice to the students of Kansas. The National Science Teachers Association supports the position that evolution is a major unifying concept of science and should be included as part of science frameworks and curricula.

It is obvious that the battle to educate children in science is still to be won. Misguided activities by the Kansas State Board of Education and others to weaken the teaching of evolution provide evidence of this. However, the progress that has been made to unfetter the science curriculum and evolution education from parochial viewpoints must continually be supported and reiterated.

Current efforts to reform schooling at the state level emphasize the use of standards and measures of accountability. As a result, 49 states have formulated standards that provide various degrees of specificity as to what K-12 students should know and be able to do. These standards are policy documents that represent a consensus by diverse audiences in each state.

A review of the science standards of 40 states shows that all include some emphasis on evolution. Various concepts important to evolutionary theory are dealt with in various degrees of specificity and comprehensiveness in these policy documents. If curriculum decisions are based on these standards, evolution will receive unprecedented emphasis in the science classrooms of this nation.

Considering the history of evolution education in this nation and the continued efforts of anti-evolutionists to intimidate policymakers and educators, it is quite significant that the science standards of most states both include and emphasize evolution. The presence of these standards, along with judicial rulings that the teaching of evolution cannot be prohibited and that equal time mandates for creationism are unconstitutional, provide science teachers with the support they need to teach effectively.

Science teachers should not be bound by censorship, pseudoscience, inconsistencies, faulty scholarship, or unconstitutional mandates as they pursue their professional responsibility to provide quality science instruction that helps students understand the natural world. And it is important that all citizens support the growing movement to place evolution in its rightful place in the biology curriculum.

NSTA encourages science educators and scientists to get involved in their local school boards to ensure that the teaching of evolution in the science classroom is a part of science frameworks and curricula.

The National Science Teachers Association is the largest organization in the world promoting excellence and innovation in science teaching and learning for all. Its 53,000-plus members include science teachers of all grade levels, science supervisors, administrators, scientists, business and industry representatives, and others involved in science education.

An NSTA Position Statement:
The Teaching of Evolution

Graphic Rule

Introductory Remarks

The National Science Teachers Association supports the position that evolution is a major unifying concept of science and should be included as part of K-College science frameworks and curricula. NSTA recognizes that evolution has not been emphasized in science curricula in a manner commensurate to its importance because of official policies, intimidation of science teachers, the general public's misunderstanding of evolutionary theory, and a century of controversy.

Furthermore, teachers are being pressured to introduce creationism, creation "science," and other nonscientific views, which are intended to weaken or eliminate the teaching of evolution.

Within this context, NSTA recommends that:

The Nature of Science, and Scientific Theories

Science is a method of explaining the natural world. It assumes the universe operates according to regularities and that through systematic investigation we can understand these regularities. The methodology of science emphasizes the logical testing of alternate explanations of natural phenomena against empirical data. Because science is limited to explaining the natural world by means of natural processes, it cannot use supernatural causation in its explanations. Similarly, science is precluded from making statements about supernatural forces, because these are outside its provenance. Science has increased our knowledge because of this insistence on the search for natural causes.

The most important scientific explanations are called "theories." In ordinary speech, "theory" is often used to mean "guess," or "hunch," whereas in scientific terminology, a theory is a set of universal statements that explain the natural world. Theories are powerful tools. Scientists seek to develop theories that

The body of scientific knowledge changes as new observations and discoveries are made. Theories and other explanations change. New theories emerge and other theories are modified or discarded. Throughout this process, theories are formulated and tested on the basis of evidence, internal consistency, and their explanatory power.

Evolution as a Unifying Concept

Evolution in the broadest sense can be defined as the idea that the universe has a history: that change through time has taken place. If we look today at the galaxies, stars, the planet Earth, and the life on planet Earth, we see that things today are different from what they were in the past: galaxies, stars, planets, and life forms have evolved. Biological evolution refers to the scientific theory that living things share ancestors from which they have diverged: Darwin called it "descent with modification." There is abundant and consistent evidence from astronomy, physics, biochemistry, geochronology, geology, biology, anthropology and other sciences that evolution has taken place.

As such, evolution is a unifying concept for science. The National Science Education Standards recognizes that conceptual schemes such as evolution "unify science disciplines and provide students with powerful ideas to help them understand the natural world," and recommends evolution as one such scheme. In addition, the Benchmarks for Science Literacy from the American Association for the Advancement of Science 's Project 2061, and the NSTA s Scope, Sequence, and Coordination Project as well as other national calls for science reform, all name evolution as a unifying concept because of its importance across the discipline of science. Scientific disciplines with a historical component such as astronomy, geology, biology, and anthropology, cannot be taught with integrity if evolution is not emphasized.

There is no longer a debate among scientists over whether evolution has taken place. There is considerable debate about how evolution has taken place: the processes and mechanisms producing change, and what has happened during the history of the universe. Scientists often disagree about their explanations. In any science, disagreements are subject to rules of evaluation. Errors and false conclusions are confronted by experiment and observation, and evolution, as in any aspect of science, is continually open to and subject to experimentation and questioning.


The word "creationism" has many meanings. In its broadest meaning, creationism is the idea that a supernatural power or powers created. Thus to Christians, Jews, and Muslims, God created; to the Navajo, the Hero Twins created. In a narrower sense, "creationism" has come to mean "special creation": the doctrine that the universe and all that is in it was created by God in essentially its present form, at one time. The most common variety of special creationism asserts that

This version of special creation is derived from a literal interpretation of Biblical Genesis. It is a specific, sectarian religious belief that is not held by all religious people. Many Christians and Jews believe that God created through the process of evolution. Pope John Paul II, for example, issued a statement in 1996 that reiterated the Catholic position that God created, but that the scientific evidence for evolution is strong.

"Creation science" is an effort to support special creationism through methods of science. Teachers are often pressured to include it or synonyms such as "intelligent design theory," "abrupt appearance theory," "initial complexity theory," or "arguments against evolution" when they teach evolution. Special creationist claims have been discredited by the available evidence. They have no power to explain the natural world and its diverse phenomena. Instead, creationists seek out supposed anomalies among many existing theories and accepted facts. Furthermore, creation science claims do not provide a basis for solving old or new problems or for acquiring new information.

Nevertheless, as noted in the National Science Education Standards "Explanations on how the natural world changed based on myths, personal beliefs, religious values, mystical inspiration, superstition, or authority may be personally useful and socially relevant, but they are not scientific." Because science can only use natural explanations and not supernatural ones, science teachers should not advocate any religious view about creation, nor advocate the converse: that there is no possibility of supernatural influence in bringing about the universe as we know it.

Legal Issues

Several judicial rulings have clarified issues surrounding the teaching of evolution and the imposition of mandates that creation science be taught when evolution is taught. Th First Amendment of the Constitution requires that public institutions such as schools be religiously neutral; because special creation is a specific, sectarian religious view, it cannot be advocated as "true," accurate scholarship in the public schools. When Arkansas passed a law requiring "equal time" for creationism and evolution, the law was challenged in Federal District Court. Opponents of the bill included the religious leaders of the United Methodist, Episcopalian, Roman Catholic, African Methodist Episcopal, Presbyterian, and Southern Baptist churches, and several educational organizations. After a full trial, the judge ruled that creation science did not qualify as a scientific theory (McLean v. Arkansas Board of Education, 529 F. Supp. 1255 (ED Ark. 1982)).

Louisiana s equal time law was challenged in court, and eventually reached the Supreme Court. In Edwards v. Aguillard, 482 U.S. 578 (1987) the court determined that creationism was inherently a religious idea and to mandate or advocate it in the public schools would be unconstitutional. Other court decisions have upheld the right of a district to require that a teacher teach evolution and not to teach creation science (Webster v. New Lennox School District #122, 917 F.2d 1003 (7th Cir. 1990); Peloza v. Capistrano Unified School District, 37 F.3d 517 (9th Cir. 1994)).

Some legislatures and policy makers continue attempts to distort the teaching of evolution through mandates that would require teachers to teach evolution as "only a theory," or that require a textbook or lesson on evolution to be preceded by a disclaimer. Regardless of the legal status of these mandates, they are bad educational policy. Such policies have the effect of intimidating teachers, which may result in the de-emphasis or omission of evolution. The public will only be further confused about the special nature of scientific theories, and if less evolution is learned by students, science literacy itself will suffer.
