In a finding that is likely to intensify the debate over what to teach students about the origins of life, a poll released yesterday found that nearly two-thirds of Americans say that creationism should be taught alongside evolution in public schools.
The poll found that 42 percent of respondents held strict creationist views, agreeing that "living things have existed in their present form since the beginning of time."
In contrast, 48 percent said they believed that humans had evolved over time. But of those, 18 percent said that evolution was "guided by a supreme being," and 26 percent said that evolution occurred through natural selection. In all, 64 percent said they were open to the idea of teaching creationism in addition to evolution, while 38 percent favored replacing evolution with creationism.
The poll was conducted July 7-17 by the Pew Forum on Religion and Public Life and the Pew Research Center for the People and the Press. The questions about evolution were asked of 2,000 people. The margin of error was 2.5 percentage points.
John C. Green, a senior fellow at the Pew Forum, said he was surprised to see that teaching both evolution and creationism was favored not only by conservative Christians, but also by majorities of secular respondents, liberal Democrats and those who accept the theory of natural selection. Mr. Green called it a reflection of "American pragmatism."
"It's like they're saying, 'Some people see it this way, some see it that way, so just teach it all and let the kids figure it out.' It seems like a nice compromise, but it infuriates both the creationists and the scientists," said Mr. Green, who is also a professor at the University of Akron in Ohio.
Eugenie C. Scott, the director of the National Center for Science Education and a prominent defender of evolution, said the findings were not surprising because "Americans react very positively to the fairness or equal time kind of argument."
"In fact, it's the strongest thing that creationists have got going for them because their science is dismal," Ms. Scott said. "But they do have American culture on their side."
This year, the National Center for Science Education has tracked 70 new controversies over evolution in 26 states, some in school districts, others in the state legislatures.
President Bush joined the debate on Aug. 2, telling reporters that both evolution and the theory of intelligent design should be taught in schools "so people can understand what the debate is about."
Senator Bill Frist of Tennessee, the Republican leader, took the same position a few weeks later.
Intelligent design, a descendant of creationism, is the belief that life is so intricate that only a supreme being could have designed it.
The poll showed 41 percent of respondents wanted parents to have the primary say over how evolution is taught, compared with 28 percent who said teachers and scientists should decide and 21 percent who said school boards should. Asked whether they believed creationism should be taught instead of evolution, 38 percent were in favor, and 49 percent were opposed.
More of those who believe in creationism said they were "very certain" of their views (63 percent), compared with those who believe in evolution (32 percent).
The poll also asked about religion and politics, government financing of religious charities, and gay men and lesbians in the military. Most of these questions were asked of a smaller pool of 1,000 respondents, and the margin of error was 2.5 percentage points, Pew researchers said.
The public's impression of the Democratic Party has changed in the last year, the survey found. Only 29 percent of respondents said they viewed Democrats as being "friendly toward religion," down from 40 percent in August of 2004. Meanwhile, 55 percent said the Republican Party was friendly toward religion.
Luis E. Lugo, the director of the Pew Forum on Religion and Public Life, said: "I think this is a continuation of the Republican Party's very successful use of the values issue in the 2004 election, and the Democrats not being able up until now to answer that successfully. Some of the more visible leaders, such as Howard Dean and others, have reinforced that image of a secular party. Of course, if you look at the Democratic Party, there's a large religious constituency there."
Survey respondents agreed in nearly equal numbers that nonreligious liberals had "too much control" over the Democratic Party (44 percent), and that religious conservatives had too much control over the Republican Party (45 percent).
On religion-based charities, two-thirds of respondents favored allowing churches and houses of worship to apply for government financing to provide social services. But support for such financing declined from 75 percent in early 2001, when Mr. Bush rolled out his religion-based initiative.
On gay men and lesbians in the military, 58 percent of those polled said they should be allowed to serve openly, a modest increase from 1994, when 52 percent agreed. Strong opposition has fallen in that time, to 15 percent from 26 percent in 1994.Correction: An article yesterday about a poll on Americans' views on the teaching of creationism misstated the margin of error of findings taken from a smaller sample of respondents who were asked about religion and politics, government financing of religious charities and gays in the military. It was 3.5 percentage points, not 2.5.
