Pennsylvania Parents Fight Teaching of 'Intelligent Design'
Posted: 09.28.05

Parents of public high school students in Dover, Pennsylvania have taken the school district to court for requiring teachers to discuss "intelligent design" -- the argument that an unknown force was involved in the creation of complex creatures like humans.

The lawsuit filed by 11 parents charges that the policy violates the principle of separation of church and state. They argue that intelligent design is little more than a modified "creationism" which says a divine being created life.

The legal battle is the latest in a national debate over how the origins of human life should be taught in public schools.

graphic showing Darwin's theory of evolutionIn October 2004, the Dover Area School District voted to require science teachers to read a statement before lessons on evolution explaining that there is a difference between theory and fact, and presents intelligent design as an alternative theory. You can read the statement in full here.

Although the Dover School District is the first district in the nation to require science teachers to mention intelligent design in their classes, several schools around the nation are considering it.

Darwinian evolution

Charles Darwin first proposed the theory of evolution in the 1859 book, "Origin of Species." Darwin's natural selection theory argues that living organisms change over time in order to adapt to their environment.

Reading and Discussion Questions

Evolutionary theory also suggests that humans evolved from apes in a slow and random change over millions of years.

Many religious institutions oppose that theory, arguing that the Bible lays out how God created man as well as plants and animals.

By the early 20th century, some states had enacted laws that banned the teaching of evolution in public schools.

When The Scopes TrialTennessee teacher John Scopes was arrested for challenging one of these laws in 1925, the case became a nationwide spectacle.

Though Scopes was found guilty for violating the law at the time, the trial was considered a victory for evolutionists since it increased pressure on states to accept the growing view of evolution as a scientifically valid theory.

In 1968, the U.S. Supreme Court prohibited laws banning the teaching of evolution in public schools in Epperson v. Arkansas, citing that it was a violation of the separation of church and state.

The court further ruled in 1987 in Edwards v. Aguillard that school districts cannot require that equal time be given to the teaching of creationism when evolution is taught.

What is intelligent design?

Proponents of intelligent design assert that Darwin's theory cannot explain the incredible intricacies of complex life forms, such as humans; therefore, such life forms must be the design of an intelligent cause, rather than an undirected process.

"Evolution is a Theory Not a Fact" graphicThe Discovery Institute, a think tank that supports intelligent design, does not think educators should teach the scientific arguments for intelligent design. Instead, they should "teach the controversy," so that students know about the alternatives to evolution.

Another organization, the Foundation for Thought and Ethics, has published a pro-intelligent design textbook for high school students titled "Of Pandas and People."

In early August, President Bush said that he felt that both evolution and intelligent design "ought to be properly taught ... so people can understand what the debate is about."

A heated debate

Critics of intelligent design, which include a majority of scientists, argue it is merely another name for creationism, the belief in the literal Genesis story of the Bible.

According to the critics, teaching intelligent design in public schools violates the Establishment Clause of the First Amendment which states, "Congress shall make no law respecting an establishment of religion."

Kenneth MillerMany scientists also denounce intelligent design as being a theory without any actual science behind it.

Kenneth Miller, a Brown University biology professor and author of a high school science textbook, testified: "To my knowledge, every single scientific society that has taken a position on this issue has taken a position against intelligent design and in favor of evolution."

The public's beliefs

Public opinion polls have consistently shown that much of the American public does not agree with the scientific community.

In a March 2005 poll conducted by NBC News, 57 percent of respondents believed that the "biblical account of creation" was the most likely explanation of the origin of humans; only 33 percent believed it was evolution.

The courts, on the other hand, have regularly argued that teaching theories such as creationism and intelligent design would violate the Constitution.

For now, the fight is in federal court and could soon wind up in the U.S. Supreme Court.
