Most biologists and other scientists contend that evolutionary theory convincingly explains the origins and development of life on Earth. So why are some Americans still arguing about it today?
…
Recently, the [PEW Research] center conducted a survey in which respondents were randomly assigned to be asked about evolution.
…
When asked the single-question version, just 18 percent of U.S adults say humans have always existed in their present form, while 81 percent say humans have evolved over time [with or without the help of God]. By contrast, in the two-question approach, nearly one third of respondents (31 percent) say humans have always existed in their present form, and 68 percent say they evolved over time. These results suggest that some Americans who do accept that humans have evolved are reluctant to say so in the two-question approach, perhaps because they are uncomfortable placing themselves on the secular side of a cultural divide.
…
These findings are in keeping with arguments by sociologists of religion that highly religious Americans may feel conflicted about saying humans have evolved, unless they are able to clarify that they also believe God had a hand in the development of life.
