Belief in evolution among Republicans has dropped more than 10 percentage points since 2009, according to a new poll by the Pew Research Center.
Pew found that 43 percent of Republicans said they believed humans and other living beings had evolved over time, down from 54 percent in 2009. More (48 percent) said they believed all living things have existed in their present form since the beginning of time.
The percentages for Democrats and independents were considerably more stable: Democratic belief in evolution went from 64 percent in 2009 to 67 percent in 2013; independent belief dipped from 67 percent in 2009 to 65 percent in 2013.
Among all American adults, 60 percent said they believe in evolution, according to Pew, and 33 percent do not.
The poll surveyed 1,983 Americans ages 18 and older from March 21 to April 8.
