"To assess public opinion on creationism, Gallup asked:
Which of the following statements comes closest to your views on the origin and development of human beings?
1) Human beings have developed over millions of years from less advanced forms of life, but God guided this process,
2) Human beings have developed over millions of years from less advanced forms of life, but God had no part in this process,
3) God created human beings pretty much in their present form at one time within the last 10,000 years or so?
Polled in November 2004, 38% of respondents chose (1), 13% chose (2), 45% chose (3), and 4% offered a different or no opinion. These results are also similar to those from previous Gallup polls, which extend back to 1982."
It also points out:
"Demographically, the article reports, belief that evolution is well-supported by the evidence is strongest "among those with the most education, liberals, those living in the West, those who seldom attend church, and ... Catholics," and weakest among "those with the least education, older Americans ..., frequent church attendees, conservatives, Protestants, those living in the middle of the country, and Republicans."

The facts that it's strongest among the young, the well-educated, and Catholics would be an indicator evolution will be increasingly accepted. All these demographics are expected to increase.
The fact that it's weakest among frequent church-goers would work against that. Church attendence is up.
It appears that the advantage is slowly leaning toward science and against creationism.
