IMAX theaters in several Southern cities have decided not to show a film on volcanoes out of concern that its references to evolution might offend those with fundamental religious beliefs.

"We've got to pick a film that's going to sell in our area. If it's not going to sell, we're not going to take it," said Lisa Buzzelli, director of an IMAX theater in Charleston that is not showing the movie. "Many people here believe in creationism, not evolution."

The film, "Volcanoes of the Deep Sea," makes a connection between human DNA and microbes inside undersea volcanoes.

The city's school board has revised its science curriculum to allow the teaching of creationism, prompting an outcry from more than 300 educators who urged that the decision be reversed.

School board members decided that a state law governing the teaching of evolution was too restrictive. The science curriculum "should not be totally inclusive of just one scientific theory," said Joni Burgin, superintendent of the district of 1,000 students in northwest Wisconsin.

Last month, when the board examined its science curriculum, language was added calling for "various models/theories" of origin to be incorporated.

The decision provoked more than 300 biology and religious studies faculty members to write a letter last week urging the board to reverse the policy. It follows a letter from 43 deans at Wisconsin public universities.

"Insisting that teachers teach alternative theories of origin in biology classes takes time away from real learning, confuses some students and is a misuse of limited class time and public funds," said Don Waller, a botanist at the University of Wisconsin at Madison.
