not the validity of evolution itself. 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." Support for new standards The hub of the intelligent design movement, the Discovery Institute and its Center for Science and Culture, played a central role in bringing about the Kansas evolution hearings, first by supporting ID proponents in their bids for seats on the board, and later in aggressively lobbying for a "Teach the Controversy" solution. Teach the Controversy is a controversial political-action campaign originating from the Discovery Institute that seeks to advance an education policy for US public schools that introduces intelligent design to public school science curricula and seeks to redefine science to allow for supernatural explanations by eliminating "methodological naturalism" from science and replacing it with "theistic realism". Teach the Controversy proponents portray evolution as a "theory in crisis." As well as proposing its own draft science standards to the Kansas State Board of Education and Critical Analysis of Evolution high school lesson plan, the Discovery Institute participated in presenting a letter to the Kansas State Board of Education from Institute associate, Dr. Philip S. Skell. A notable intelligent design proponent, Dr. Skell's letter to the board touts the alleged benefits of the Teach the Controversy approach, as well his credentials as a member of the National Academy of Sciences, despite the fact the National Academy of Sciences issued a policy statement against the Teach the Controversy solution and intelligent design as a concept.
