A bill calling for "balanced treatment to the theory of scientific creationism and the theory of evolution" was introduced in the Mississippi Senate and referred to the Committee on Education on January 10, 2005. Introduced by Senator Gary Jackson, who represents the 15th Senate District, SB 2286 defines "scientific creationism" as "the belief, based on scientific principles, that there was a time in the past when all matter, energy and life, and their processes and relationships, were created ex nihilo and fixed by creative and intelligent design," and would, if enacted, require "instruction in scientific theories of both evolution and scientific creationism if public schools choose to teach either." Only K-12 instruction would be affected by the bill. In both its title and in particular choices of phrasing, SB 2286 seems to be modeled on Lousiana's "Balanced Treatment for Creation-Science and Evolution-Science in Public School Instruction," which was held to be unconstitutional in the Supreme Court's 1987 decision in Edwards v. Aguillard.
