In early 2006 Representative Sally Kern introduced an anti-evolution 'Academic Freedom' bill (HB2107) into the Oklahoma House, which passed it by a vote of 77-10 on March 2, 2006. Also in 2006 Senator Daisy Lawler introduced another anti-evolution bill, based upon language in the Santorum Amendment, in the Oklahoma Senate. Both bills (and two further, unrelated, anti-evolution bills) lapsed with the end of the 2006 legislative session.
In February 2009 a bill titled the 'Scientific Education and Academic Freedom Act' (SB 320) was introduced by Senator Randy Brogdon and died in committee the Oklahoma Senate. The bill is nearly identical to the Act passed in 2008 in Louisiana.
