NEW ORLEANS - Louisiana Republican Gov. Bobby Jindal has signed into law a bill that critics say could allow for the teaching of "creationism" alongside evolution in public schools.

Jindal, a conservative Christian who has been touted by pundits as a potential vice presidential running mate for Republican presidential candidate John McCain, signed the legislation earlier this week.

The law will allow schools if they choose to use "supplemental materials" when discussing evolution but does not specify what the materials would be.

It states that authorities "shall allow ... open and objective discussion of scientific theories being studied including, but not limited to, evolution, the origins of life, global warming and human cloning.
