evolution education and opposing intelligent design. Scientific controversies are minor and concern the details of the mechanisms of evolution, not the validity of the overarching theory of evolution. In the absence of an actual professional controversy between groups of experts on evolution, critics say intelligent design proponents have merely renamed the conflict that already existed between biologists and creationists, and that the controversy to which intelligent design proponents refer is political in nature and thus, by definition, outside of the realm of science and scientific educational curricula. Critics contend that intelligent design proponents ignore this point by continuing to make the claim of a "scientific controversy." According to Thomas Dixon, "The 'controversy' in question has not arisen from any substantial scientific disagreement but is the product of a concerted public relations exercise aimed at the Christian parents of America." For example, the National Association of Biology Teachers, in a statement endorsing evolution as noncontroversial, quoted Theodosius Dobzhansky: "Nothing in biology makes sense except in the light of evolution" and went on to state that the quote "accurately reflects the central, unifying role of evolution in biology. The theory of evolution provides a framework that explains both the history of life and the ongoing adaptation of organisms to environmental challenges and changes." They emphasized that "Scientists have firmly established evolution as an important natural process" and that "The selection of topics covered in a biology curriculum should accurately reflect the principles of biological science. Teaching biology in an effective and scientifically honest manner requires that evolution be taught in a standards-based instructional framework with effective classroom discussions and laboratory experiences." Prominent evolutionary biologists such as Richard Dawkins and Jerry Coyne have proposed various "controversies" that are worth teaching, instead of intelligent design. Dawkins compares teaching intelligent design in schools to teaching flat earthism: perfectly fine in a history class but not in science. "If you give the idea that there are two schools of thought within science, one that says the earth is round and one that says the earth is flat, you are misleading children". Tufts University Professor of Philosophy Daniel C. Dennett, author of Darwin's Dangerous Idea, describes how they generate a sense of controversy: "The proponents of intelligent design use an ingenious ploy that works something like this: First you misuse or misdescribe some scientist's work. Then you get an angry rebuttal. Then, instead of dealing forthrightly with
