WASHINGTON – (PRNewswire-USNewswire) – Six-in-ten Americans say "humans and other living things have evolved over time," while a third (33 percent) reject the idea of evolution, saying "humans and other living things have existed in their present form since the beginning of time," according to a new Pew Research Center analysis.
The share of the general public saying that humans have evolved over time is about the same as in 2009, when Pew Research last asked the question.
About half of those who express a belief in human evolution take the view that evolution is "due to natural processes such as natural selection" (32 percent of the American public overall). But many Americans believe God or a supreme being played a role in the process of evolution. Roughly a quarter of adults (24 percent) say "a supreme being guided the evolution of living things for the purpose of creating humans and other life in the form it exists today."
Among other key findings:
• Beliefs about evolution differ strongly by religious group. White evangelical Protestants are particularly likely to believe humans have existed in their present form since the beginning of time. Roughly two-thirds (64 percent) express this view, as do half of black Protestants (50 percent). Only 15 percent of white mainline Protestants share this opinion.
• There are sizable differences by party affiliation in beliefs about evolution, and the gap between Republicans and Democrats has grown. In 2009, 54 percent of Republicans and 64 percent of Democrats said humans have evolved over time, a difference of 10 percentage points. Today, 43 percent of Republicans and 67 percent of Democrats say humans have evolved, a 24-point gap.
• Beliefs about evolution tend to vary by gender, age and education. Men are somewhat more inclined than women to say humans and other living things have evolved over time. Younger adults are more likely than older Americans to express belief in evolution.
The nationwide Pew Research Center survey was conducted March 21-April 8, 2013, with a representative sample of 1,983 adults.
