OKLAHOMA CITY (AP) - The Oklahoma House has adopted legislation authorizing public schools to teach Oklahoma high school students that life begins at conception.

      Without debate, House members on Tuesday voted 64-12 for the measure and sent it to the Senate for a vote. The National Right to Life Committee, the nation's largest anti-abortion organization, says Oklahoma is the first state to introduce such a bill.

      The Humanity of the Unborn Child Act requires Oklahoma public high schools to teach students in grades nine through 12 "about the humanity of a child in utero," including details about how a fetus develops at certain stages of pregnancy.

      Its author, Republican Rep. Ann Coody of Lawton, says the parents of high school students could opt their children out of the program.
