Many conservatives, including the chairman of the State Board of Education, have long wanted biology teachers in Texas to address issues that some national groups and scientists say expose weaknesses in the theory of evolution.
They stress that they aren't pushing for schools to teach creationism or intelligent design, a theory that says certain features of the universe are so complex that they are best explained by an intelligent cause, not an undirected process such as natural selection.
But their opponents argue that there is no debate: Research consistently supports evolution. They argue that attempts to discredit Charles Darwin's theory of evolution amount to sneaking God into the classroom under the guise of intelligent design.
It is still mystifying to me how an educational agency can muddy the waters with regard to established scientific theory. It shows how well the "teach the controversy" smokescreen has worked.
