Teaching evolution has come a long way in the United States, with a bright future ahead. A century after the famous Scopes trial, where teacher John T. Scopes was convicted for violating a state law that forbade the teaching of evolution, there are now hopeful prospects for the unifying principle of the biological sciences in American classrooms.
The Scopes trial, which took place in Dayton, Tennessee in 1925, marked a turning point in the fight for the teaching of evolution. Although Scopes was initially convicted, the decision was later overturned on appeal. However, laws banning the teaching of evolution persisted in various states until the late 1960s and early 1970s.
Subsequent attempts to undermine the teaching of evolution in public schools focused on balancing it with alternatives such as creationism, creation science, and intelligent design. These efforts were thwarted by federal court decisions, including the landmark 2005 case of Kitzmiller v. Dover, where a Pennsylvania school district’s policy of promoting intelligent design was found unconstitutional.
In the early 21st century, a new wave of attacks emerged, seeking to misrepresent evolution as scientifically controversial. Some states passed laws allowing teachers to present creationism as a credible alternative to evolution. Despite these challenges, the teaching of evolution in American public schools has been steadily improving.
Recent surveys of high school biology teachers show a greater emphasis on evolution, including human evolution. State science standards now reflect the importance of teaching evolution as a core principle of the life sciences. However, there is still room for improvement, as some teachers continue to present creationism as a scientifically credible alternative.
While concerns remain about ongoing attempts to undermine the teaching of evolution, acceptance of evolution has become a majority position among the American public. There are signs of a shift even among religious communities traditionally hostile to evolution. Ultimately, there is reason to hope that every student in the U.S. public schools will one day appreciate the importance of evolution in understanding the biological world.
