On Friday, Gallup published the results of a poll which probed American opinions on the origins of the human species. The results: 46% of Americans believe in straight-up creationism, 32% believe in so-called "intelligent design," and a mere 15% believe humans evolved via natural selection.

Gallup conducted the poll with a random sample of 1,012 Americans. The demographic breakdown for responders was neatly summarized at CNN.com:

Nearly 70% of respondents who attend church every week said that God created humans in their present form, compared with 25% of people who seldom or never attend church.

Among the seldom church-goers, 38% believe that humans evolved with no guidance from God.

The numbers also showed a tendency to follow party lines, with nearly 60% of Republicans identifying as creationists, while 41% of Democrats hold the same beliefs.

Republicans also seem to be more black-and-white about their beliefs, with only 5% responding that humans evolved with some help from God. That number is much lower than the 19% of both independents and Democrats.

Over at Gallup, a helpful chart shows the evolution of Americans' opinions on evolution over the last 30 years. It's not pretty. Very little has changed since 1982, when 44% of Americans were creationists, 38% believed in "intelligent design," and 9% came out for natural selection.

Lest you think the Gallup results are mistaken, take a quick peek at the comments section over at CNN's coverage of the poll. It's a proud and appalling parade of ignorance.
