I have found the emboldened line below (my emphasis) to be very true:
The evidence is clear, as in a February 2009 Gallup Poll, taken on the eve of the 200th anniversary of Charles Darwin’s birthday, that reported only 39 percent of Americans say they “believe in the theory of evolution,” while a quarter say they do not believe in the theory, and another 36 percent don’t have an opinion either way.
The same poll correlated belief in evolution with educational level: 21 percent of people with a high school education or less believed in evolution. That number rose to 41 percent for people with some college attendance, 53 percent for college graduates, and 74 percent for people with a postgraduate education.
Clearly, the level of education has an impact on how people feel about evolution.
