In 2001, 45% of the American public believed that, God created people in present form within last 10,000 years. 37% believe that Evolution occurred over millions of years guided by God. Only 12% believe that Evolution occurred with
no interference by God.
And 9% don't know.

So only 12% believe in the standard scientific theory. 37% believe in some adaptation of that. And the other half the country doesn't believe in any variation of what science has overwhelmingly accepted for most of a century.

Cheers,
