What in creation ... ?
You can't interject faith into study of life without becoming unscientific

Ten years ago, Carl Sagan shared his view that "our species needs, and deserves, a citizenry with minds wide awake and a basic understanding of how the world works."
This year, 80 years after the prosecution of John Scopes for teaching evolution at a Tennessee school, the debate between scientific knowledge and religious belief over the origins of life has roared back into the news. Reporters from around the globe are in Harrisburg, Pa., covering what is anticipated to be a landmark case. It raises the question of whether evolution should be taught in ninth-grade biology classes in nearby Dover as an entirely natural process or if the students in those classes also should hear about an intelligent force that, from time to time, has intervened in the process.
This is not a new argument. Nor is it new that scientific research frequently refines our understanding of age-old questions, including those that give us a more detailed grasp of how life has left a record of its past existence and led to today's biodiversity.
Before entering the field of natural history museums and science technology centers, I was a geologist. I had a childhood fascination with the change, after storms, in the shape of sea cliffs near where I lived, and the fresh supply of fossils I could find.
Looking back, the late 1960s and early 1970s were a great time to pursue geology at high school and university, because several major questions were being resolved. Applying World War II technology to locate submarines, geologists suddenly had complete ocean-floor maps. Teaching textbooks could barely keep up with the new understanding that the distribution and cause of volcanic eruptions and major earthquakes are tied to the dynamic boundaries of giant plates that compose the Earth's crust. Geologists determined the rates of plate motion to be just inches per year -- so slow, yet capable of opening up a 3,000-mile-wide ocean over 100 million years. Such a time span is a mere 2 percent of the dateable 4.6-billion-year age of the Earth.
Geologists then realized the implications of continental movements for how ocean currents, climate, landforms and life's ecosystems have changed over time.
This revolution in thinking led to what is widely called the unifying theory of plate tectonics. A theory in science is a structure of interrelated ideas to explain one or more phenomena in the natural world. The huge Indonesian earthquake and resulting Indian Ocean tsunami of last Dec. 26 were explained by news media within the framework of our understanding from scientific research.
It is the very nature of science to add insight and knowledge as new research re-examines previous research. This applies as much to the processes at work in the Earth's crust as it does to the process of, and evidence for, the evolution of life on Earth over the eons of geological time. As humans, we are certainly the most complex beings to have ever inhabited this planet: We think, we imagine, we question, we study, we debate and develop our opinions.
Science has never claimed to know everything. What we can clearly see from the history of scientific research is that the frontiers of knowledge have relentlessly edged forward, sometime as newsworthy leaps but usually as small steps that are out of public view at conferences and in journals. Sometimes, because of better analytical tools, new research may completely replace what earlier work had concluded. As an example, before it was established how continents move, the jigsaw fit of the Atlantic coastlines of South America and Africa had been interpreted as evidence that the area in between had sunk to become new ocean floor rather than the result of one larger continent breaking into two and slowly drifting apart.
At this time of seemingly contradictory reports of evidence and viewpoints about life itself, dictionary definitions of science and religion are worthwhile material for reflection. Science is a method-driven activity based on replicable observations, experimental investigations and theoretical modeling. Religion is a belief in, and reverence for, a supernatural power at the individual or institutional level.
Creationism and intelligent design are not new ways of thinking. Their first use dates back to when the idea of evolution was in its early stages, most famously by Charles Darwin. As recalled last month in the New York Times Magazine by William Safire, creationism was coined in 1868 to oppose Darwinism, and intelligent design, in its current sense, was first used in 1903. These two religious concepts are markedly different. Creationism, which arose in its current context in the 1970s, rejects the evidence of the fossil record and the vastness of geological time and, instead, takes a literal belief that the Earth was created according to the Book of Genesis in the Bible. Intelligent design, which has intensely re-entered the news this year, accepts scientific interpretations of fossils and geological time but attributes the most complex, and as yet incompletely understood, parts of the evolutionary record, including its beginning, as moments of possibly supernatural intervention.
The record of ancient life is understandably incomplete. Its so-called "gaps" are the result of the varying nature of environments in which life occurs and whether or not conditions are right to bury and preserve an organism. Galleries in natural-history museums present evidence from the fossil record, and their text panels may include explanations of how new discoveries are shortening and sometimes eliminating the gaps.
In general, it would be beneficial for those engaged in science to spend more time explaining their work to society. For their part, science museums and science centers try to build a stronger public grasp of science, and in particular to support schools in the teaching and learning of science. These institutions do not -- nor should they ever -- ask visitors to leave their religion behind as they enter. Concerned perhaps that they may add to controversies, institutions that exist to link the public with science seldom speak up.
Earlier this year, several science museums in Southern states were in the national eye for their position not to show IMAX films that state or imply the process of evolution. It is worthwhile noting that the word "museum" stems from the Greek Mousieos, meaning "of the Muses." The Muses were Greek goddesses inspiring the reflective pursuit of the arts and sciences.
Science and faith need not be at odds, but they do need to be kept separate. It is vital that science be taught and understood as science based on a globally accumulating body of knowledge. It is equally critical that faith be taught and understood as belief, recognizing that religious views on scientific subjects vary among nations as well as over time. Perhaps this is why news reporters from around the world are following the court case in Pennsylvania with such interest.
