A comparison of peoples' views in 34 countries finds that the United States ranks near the bottom when it comes to public acceptance of evolution. Only Turkey ranked lower.
Among the factors contributing to America's low score are poor understanding of biology, especially genetics, the politicization of science and the literal interpretation of the Bible by a small but vocal group of American Christians, the researchers say.
“American Protestantism is more fundamentalist than anybody except perhaps the Islamic fundamentalist, which is why Turkey and we are so close,” said study co-author Jon Miller of Michigan State University.

Of the other countries surveyed, only Turkey ranked lower, with about 25 percent of the population accepting evolution and 75 percent rejecting it. In Iceland, Denmark, Sweden and France, 80 percent or more of adults accepted evolution; in Japan, 78 percent of adults did.

The researchers also compared 10 independent variables—including religious belief, political ideology and understanding of concepts from genetics, or “genetic literacy”—between adults in America and nine European countries to determine whether these factors could predict attitudes toward evolution.

The researchers also single out the poor grasp of biological concepts, especially genetics, by American adults as an important contributor to the country's low confidence in evolution.
“The more you understand about genetics, the more you understand about the unity of life and the relationship humans have to other forms of life,” Miller said.
The current study also analyzed the results from a 10-country survey in which adults were tested with 10 true or false statements about basic concepts from genetics. One of the statements was "All plants and animals have DNA." Americans had a median score of 4. (The correct answer is "yes.")
