Call 2012 the Year of the Copycat. Many of the antievolution bills proposed this year were old bills that were simply dusted off and offered up as new.
A 2011 Tennessee bill—largely drawn from Louisiana's infamous 2008 Science Education Act—was revived and signed into law in April. Among other things, this classic "academic freedom" bill lets teachers "help" students critique evolution, global warming, and more. This means there are now two states in the Union—Louisiana and Tennessee—that have anti-evolution and anti-climate change education laws on the books.
