In 2002, school officials in Cobb County, Georgia placed stickers with this text inside a set of biology textbooks:
“This textbook contains material on evolution. Evolution is a theory, not a fact, regarding the origin of living things. This material should be approached with an open mind, studied carefully and critically considered.”
By saying that evolution is “just a theory,” the stickers lead people to believe that the theory of evolution is nothing more than a proposed guess that can be easily discredited. But that’s not the case at all – a significant amount of evidence exists behind the theory of evolution.
