HELENA, Mont. (AP) — Lawmakers are considering a bill that critics say would pave the way for teaching creationism alongside evolution.

Republican sponsor Clayton Fiscus of Billings says evolution isn't settled science. His bill would allow teachers — if they want to — to address weaknesses in evolution studies in the classroom.

The bill says it does not promote the teaching of religious doctrine. But critics argue it will allow such instruction.

The opponents say courts have ruled that the teaching of religious creationism is unconstitutional.

The House Education Committee didn't take immediate action Friday on the proposal. There were no supporters, and roughly two dozen opponents.

Social conservatives are preparing to take another hot-button issue to the committee on Monday. They are seeking limits on local sex education curriculum.
