In districts around the country, even when evolution is in the curriculum it may not be in the classroom, according to researchers who follow the issue.
Teaching guides and textbooks may meet the approval of biologists, but superintendents or principals discourage teachers from discussing it. Or teachers themselves avoid the topic, fearing protests from fundamentalists in their communities.
"The most common remark I've heard from teachers was that the chapter on evolution was assigned as reading but that virtually no discussion in class was taken," said Dr. John R. Christy, a climatologist at the University of Alabama at Huntsville, an evangelical Christian and a member of Alabama's curriculum review board who advocates the teaching of evolution. Teachers are afraid to raise the issue, he said in an e-mail message, and they are afraid to discuss the issue in public.
Dr. Frandsen, former chairman of the committee on science and public policy of the Alabama Academy of Science, said in an interview that this fear made it impossible to say precisely how many teachers avoid the topic.
"You're not going to hear about it," he said. "And for political reasons nobody will do a survey among randomly selected public school children and parents to ask just what is being taught in science classes."
The article, though should have had this sentence right up front:
There is no credible scientific challenge to the idea that all living things evolved from common ancestors, that evolution on earth has been going on for billions of years and that evolution can be and has been tested and confirmed by the methods of science.
But this also needs to be said:
...in a 2001 survey, the National Science Foundation found that only 53 percent of Americans agreed with the statement "human beings, as we know them, developed from earlier species of animals."
And this was good news to the foundation. It was the first time one of its regular surveys showed a majority of Americans had accepted the idea. According to the foundation report, polls consistently show that a plurality of Americans believe that God created humans in their present form about 10,000 years ago, and about two-thirds believe that this belief should be taught along with evolution in public schools.
These findings set the United States apart from all other industrialized nations, said Dr. Jon Miller, director of the Center for Biomedical Communications at Northwestern University, who has studied public attitudes toward science. Americans, he said, have been evenly divided for years on the question of evolution, with about 45 percent accepting it, 45 percent rejecting it and the rest undecided.
In other industrialized countries, Dr. Miller said, 80 percent or more typically accept evolution, most of the others say they are not sure and very few people reject the idea outright.
"In Japan, something like 96 percent accept evolution," he said. Even in socially conservative, predominantly Catholic countries like Poland, perhaps 75 percent of people surveyed accept evolution, he said. "It has not been a Catholic issue or an Asian issue," he said.
Indeed, two popes, Pius XII in 1950 and John Paul II in 1996, have endorsed the idea that evolution and religion can coexist. "I have yet to meet a Catholic school teacher who skips evolution," Dr. Scott said.
