In support of what jedberg said, the Texas State Board of Education reviews school books and votes on which books to buy, and has the power to get the book authors to change books to their liking. That board, with the help of the Governor, was packed with creationists. Science books had to "teach the controversy" and treat creationism as being as valid as evolution. And guess which religion's creation story is the one chosen? It wasn't about science, it wasn't about religious tolerance; it is about their desire to see government run by their evangelical religion. The board chair was for many years was Don McLeroy. He is a dentist without any particular educational pedigree. What he had going for him was zeal to promote the cause, nothing more. It wasn't just science books affected, of course. History books cut out Jefferson to make room for Reagan and Phyllis Shlafly. When you are far to either side, even centrist information looks biased. The SBOE believed the textbooks had terrible liberal bias and needed to be fixed. If you are an American student and have textbooks, they are far from liberal.
