Seven of 10 Republicans skeptical on evolution: Four in 10 Democrats too

Republicans are far more likely to doubt the theory of evolution than Democrats, according to a new Gallup Poll.

Sixty-eight percent of Republicans say they doubt that humans evolved from lower life forms over millions of years, while only 40 percent of Democrats hold that view. The poll was conducted by telephone June 1-3 and has a margin of error of plus or minus three percentage points.
