A last-ditch legislative attempt to attack the teaching of evolution and of climate change in Oklahoma failed when a legislative deadline passed.

Scientific and educational organizations are again expressing their opposition to antiscience legislation in the Sooner State.

The attack on the teaching of evolution and of climate change in Oklahoma continues, despite the failure of House Bill 1551 and Senate Bill 1742.

Oklahoma's House Bill 1551, one of two bills attacking the teaching of evolution and of climate change active in the Oklahoma legislature during 2012, is now in effect dead, according to Oklahomans for Excellence in Science Education.

As Oklahoma's House Bill 1551 is under consideration in a state senate committee, the American Association for the Advancement of Science, the National Association of Biology Teachers, and the National Association of Geoscience Teachers have all expressed their opposition to the bill, which would, if enacted, encourage teachers to present the "scientific strengths and scientific weaknesses" of "controversial" topics such as "biological evolution" and "global warming."
