A Gallup poll that was released on Monday reported that the percentage of Americans who support the theory of evolution has doubled in the past 30 years, while those who believe in at least some kind of religious or divine intervention has slightly decreased.

The increase can be partly attributed to the Generations Y and Z, stating that “younger people are more likely to have a secularist view of evolution than other groups, while people living in the South are more likely to be creationist,” according to a United Press International article.

Business Insider described millennials as “godless" to illustrate the extent of their disbelief in divine intervention. The Gallup poll reported that nearly two-thirds of 18 to 29 year olds support evolution, compared to just 11 percent of 50 to 64 year olds. But age is not a clear-cut determinant: About 16 percent of those 65 and over believe in evolution.

The Gallup poll also found that a college graduate is more likely to support the theory of evolution than someone without a high school diploma, indicating how education is the clearest metric for determining such beliefs.
