(RNS) Four in 10 Americans believe that God created humans in something like their present form within the last 10,000 years, according to a new Gallup Poll.

While that percentage represents a slight dip from 2008, when 44 percent said they do not believe divinely made humans evolved over time, it has remained remarkably stable since 1982, the earliest year for which Gallup provided data.

Nearly as many Americans (38 percent in 2010) say they believe humans evolved over time, but that God guided the process. That percentage, too, has remained consistent since 1982.

Meanwhile, the number of Americans who believe humans evolved apart from any divine intervention crept up from 14 percent in 2008 to 16 percent this year. With few exceptions, that number has risen — albeit slightly — from 1982.

Gallup’s 2010 poll was based on telephone interviews of 1,018 adults conducted Dec. 10-12. The margin of error is plus or minus 4 percentage points.
