GOP presidential hopeful Rick Perry says evolution is "a theory" with "some gaps in it."

The Texas governor was responding to a question from a little boy in New Hampshire, who was prompted by his mother to ask the Republican candidate about the age of the Earth and evolution.

"I hear your mom was asking about evolution," Perry said today. "That's a theory that is out there -- and it's got some gaps in it."

Perry then told the boy: "In Texas, we teach both creationism and evolution. I figure you're smart enough to figure out which one is right."

State education experts told the Texas Tribune that Perry is not quite right about what's taught in the Lone Star state's public schools.

David Bradley, a conservative member of the Texas Board of Education, told the Tribune that nothing prevents a teacher from talking about creationism but "it is not specifically in the Texas curriculum."

Kathy Miller, president of the Texas Freedom Network, is quoted in the same story as saying, "Texas science standards do not call for teaching creationism in the classroom."

The Supreme Court in 1987 ruled that a Louisiana law that required creation science to be taught in schools was unconstitutional.

During his 2010 re-election bid in Texas, Perry said he is a "firm believer in intelligent design as a matter of faith and intellect," according to his responses to questions from the Standard-Times in San Angelo, Texas.

The Texas governor caused a stir on Wednesday when he said he didn't believe in man-made global warming.

Jon Huntsman, a former Utah governor also seeking the GOP presidential nomination, tweeted today: "To be clear. I believe in evolution and trust scientists on global warming. Call me crazy."
