With three admitted skeptics of modern biology seeking the Republican presidential nomination (Huckabee, Brownback, and Tancredo), there’s far more interest than usual in evolution and politics. USA Today added to the interest late last week with a report that showed two-thirds of Americans believe “creationism, the idea that God created humans in their present form within the past 10,000 years, is definitely or probably true.”

Gallup followed up today with some pertinent details — including the partisan breakdown.

The majority of Republicans in the United States do not believe the theory of evolution is true and do not believe that humans evolved over millions of years from less advanced forms of life. This suggests that when three Republican presidential candidates at a May debate stated they did not believe in evolution, they were generally in sync with the bulk of the rank-and-file Republicans whose nomination they are seeking to obtain.

Independents and Democrats are more likely than Republicans to believe in the theory of evolution. But even among non-Republicans there appears to be a significant minority who doubt that evolution adequately explains where humans came from.

The problem isn’t just that Americans in general are confused, but rather that the GOP is throwing off the curve.
