Final answer:
The specific percentage from the Gallup survey on adults who believe in evolution is not provided, but public opinion on such topics can vary and is influenced by several factors. A similar instance is seen where about 80 million Americans believed in extraterrestrial visits to Earth. Such survey results highlight the disparity between scientific consensus and public belief.
Step-by-step explanation:
The question pertains to a Gallup survey on the percentage of adults who believe in evolution as the explanation for human existence on Earth. While the specific percentage from the Gallup survey is not provided in the materials referenced, it is clear that public opinion on scientific theories can vary significantly. For example, a 2012 Kelton Research poll found that 36 percent of adult Americans believed that alien beings have landed on Earth. This example illustrates using scientific notation that approximately 80 million adults held this belief.
Surveys and polls can differ based on sample size, methodology, and the population sampled. Thus, it would be important to examine the Gallup survey's methodology to understand how the reported percentage was derived. Additionally, historical context may influence public opinion; for instance, the theory of evolution has been controversial since its inception, impacting its acceptance among the general public. It's worth noting that while the theory of evolution is well-supported scientifically, public understanding and acceptance can lag behind scientific consensus, as seen with climate change where a substantial portion of Americans is unaware of the nearly unanimous agreement among climate scientists on anthropogenic climate change.
