Darwin on the Right

Why Christians and conservatives should accept evolution

By Michael Shermer

According to a 2005 Pew Research Center poll, 70 percent of evangelical Christians believe that living beings have always existed in their present form, compared with 32 percent of Protestants and 31 percent of Catholics. Politically, 60 percent of Republicans are creationists, whereas only 11 percent accept evolution, compared with 29 percent of Democrats who are creationists and 44 percent who accept evolution. A 2005 Harris Poll found that 63 percent of liberals but only 37 percent of conservatives believe that humans and apes have a common ancestry. What these figures confirm for us is that there are religious and political reasons for rejecting evolution. Can one be a conservative Christian and a Darwinian? Yes. Here's how.

  • 1. Evolution fits well with good theology. Christians believe in an omniscient and omnipotent God. What difference does it make when God created the universe--10,000 years ago or 10,000,000,000 years ago? The glory of the creation commands reverence regardless of how many zeroes in the date. And what difference does it make how God created life--spoken word or natural forces? The grandeur of life's complexity elicits awe regardless of what creative processes were employed. Christians (indeed, all faiths) should embrace modern science for what it has done to reveal the magnificence of the divine in a depth and detail unmatched by ancient texts. Calling God a watchmaker is belittling.
  • 2. Creationism is bad theology. The watchmaker God of intelligent-design creationism is delimited to being a garage tinkerer piecing together life out of available parts. This God is just a genetic engineer slightly more advanced than we are. An omniscient and omnipotent God must be above such humanlike constraints. As Protestant theologian Langdon Gilkey wrote, "The Christian idea, far from merely representing a primitive anthropomorphic projection of human art upon the cosmos, systematically repudiates all direct analogy from human art." Calling God a watchmaker is belittling.
  • 3. Evolution explains original sin and the Christian model of human nature. As a social primate, we evolved within-group amity and between-group enmity. By nature, then, we are cooperative and competitive, altruistic and selfish, greedy and generous, peaceful and bellicose; in short, good and evil. Moral codes and a society based on the rule of law are necessary to accentuate the positive and attenuate the negative sides of our evolved nature.
  • 4. Evolution explains family values. The following characteristics are the foundation of families and societies and are shared by humans and other social mammals: attachment and bonding, cooperation and reciprocity, sympathy and empathy, conflict resolution, community concern and reputation anxiety, and response to group social norms. As a social primate species, we evolved morality to enhance the survival of both family and community. Subsequently, religions designed moral codes based on our evolved moral natures.
  • 5. Evolution accounts for specific Christian moral precepts. Much of Christian morality has to do with human relationships, most notably truth telling and marital fidelity, because the violation of these principles causes a severe breakdown in trust, which is the foundation of family and community. Evolution describes how we developed into pair-bonded primates and how adultery violates trust. Likewise, truth telling is vital for trust in our society, so lying is a sin.
  • 6. Evolution explains conservative free-market economics. Charles Darwin's "natural selection" is precisely parallel to Adam Smith's "invisible hand." Darwin showed how complex design and ecological balance were unintended consequences of competition among individual organisms. Smith showed how national wealth and social harmony were unintended consequences of competition among individual people. Nature's economy mirrors society's economy. Both are designed from the bottom up, not the top down. Because the theory of evolution provides a scientific foundation for the core values shared by most Christians and conservatives, it should be embraced. The senseless conflict between science and religion must end now, or else, as the Book of Proverbs (11:29) warned: "He that troubleth his own house shall inherit the wind."

Scientists on Religion

Theist and materialist ponder the place of humanity in the universe

By George Johnson

HELIX NEBULA, also known as the eye of God

God's Universe by Owen Gingerich Belknap Press (Harvard University Press), 2006 The Language of God: A Scientist Presents Evidence for Belief by Francis S. Collins Free Press (Simon & Schuster), 2006 The God Delusion by Richard Dawkins Houghton Mifflin, 2006 The Varieties of Scientific Experience: A Personal View of the Search for God by Carl Sagan. Edited by Ann Druyan Penguin Press, 2006 Ten years after his death in 1996, science writer Walter Sullivan's byline occasionally still appears in the New York Times on obituaries of important physicists, as though he were beckoning them to some quantum-mechanical heaven. This is not a case of necromancy--the background material for Times obits is often written in advance and stored. If the dead really did communicate with the living, that would be a scientific event as monumental as the discovery of electromagnetic induction, radioactive decay or the expansion of the universe. Laboratories and observatories all over the world would be fiercely competing to understand a new phenomenon. One can imagine Mr. Sullivan, the ultimate foreign correspondent, eagerly reporting the story from the other side.

Light is carried by photons, gravity by gravitons. If there is such a thing as spiritual communication, there must be a means of conveyance: some kind of "spiritons"--ripples, perhaps, in one of M Theory's leftover dimensions. Some theologians might scoff at that remark, yet there has been a resurgence in recent years of "natural theology"--the attempt to justify religious teachings not through faith and scripture but through rational argument, astronomical observations and even experiments on the healing effects of prayer. The intent is to prove that, Carl Sagan be damned, we are not lost among billions and billions of stars in billions and billions of galaxies, that the universe was created and is sustained for the benefit of God's creatures, the inhabitants of the third rock from the sun.

In God's Universe, Owen Gingerich, a Harvard University astronomer and science historian, tells how in the 1980s he was part of an effort to produce a kind of anti-Cosmos, a television series called Space, Time, and God that was to counter Sagan's "conspicuously materialist approach to the universe." The program never got off the ground, but its premise survives: that there are two ways to think about science. You can be a theist, believing that behind the veil of randomness lurks an active, loving, manipulative God, or you can be a materialist, for whom everything is matter and energy interacting within space and time. Whichever metaphysical club you belong to, the science comes out the same. In the hands of as fine a writer as Gingerich, the idea almost sounds convincing. "One can believe that some of the evolutionary pathways are so intricate and so complex as to be hopelessly improbable by the rules of random chance," he writes, "but if you do not believe in divine action, then you will simply have to say that random chance was extremely lucky, because the outcome is there to see. Either way, the scientist with theistic metaphysics will approach laboratory problems in much the same way as his atheistic colleague across the hall." Thus, a devoutly Christian geneticist such as Francis S. Collins, author of The Language of God and leader of the Human Genome Project, can comfortably accept that "a common ancestor for humans and mice is virtually inescapable" or that it may have been a mutation in the FOXP2 gene that led to the flowering of human language. The genetic code is, after all, "God's instruction book."

But what sounds like a harmless metaphor can restrict the intellectual bravado that is essential to science. "In my view," Collins goes on to say, "DNA sequence alone, even if accompanied by a vast trove of data on biological function, will never explain certain special human attributes, such as the knowledge of the Moral Law and the universal search for God." Evolutionary explanations have been proffered for both these phenomena. Whether they are right or wrong is not a matter of belief but a question to be approached scientifically. The idea of an apartheid of two separate but equal metaphysics may work as a psychological coping mechanism, a way for a believer to get through a day at the lab. But theism and materialism don't stand on equal footings. The assumption of materialism is fundamental to science. Richard Dawkins, in The God Delusion, tells of his exasperation with colleagues who try to play both sides of the street: looking to science for justification of their religious convictions while evading the most difficult implications--the existence of a prime mover sophisticated enough to create and run the universe, "to say nothing of mind reading millions of humans simultaneously." Such an entity, he argues, would have to be extremely complex, raising the question of how it came into existence, how it communicates--through spiritons!--and where it resides.

Dawkins is frequently dismissed as a bully, but he is only putting theological doctrines to the same kind of scrutiny that any scientific theory must withstand. No one who has witnessed the merciless dissection of a new paper in physics would describe the atmosphere as overly polite. Sagan, writing from beyond the grave (actually his new book, The Varieties of Scientific Experience, is an edited version of his 1985 Gifford Lectures), asks why, if God created the universe, he left the evidence so scant. He might have embedded Maxwell's equations in Egyptian hieroglyphs. The Ten Commandments might have been engraved on the moon. "Or why not a hundred-kilometer crucifix in Earth orbit?... Why should God be so clear in the Bible and so obscure in the world?"

He laments what he calls a "retreat from Copernicus," a loss of nerve, an emotional regression to the idea that humanity must occupy center stage. Both Gingerich and Collins, along with most every reconciler of science and religion, invoke the anthropic principle: that the values of certain physical constants such as the charge of the electron appear to be "fine-tuned" to produce a universe hospitable to the rise of conscious, worshipful life. But the universe is not all that hospitable--try leaving Earth without a space-suit. Life took billions of years to take root on this planet, and it is an open question whether it made it anywhere else. To us carboniferous creatures, the dials may seem miraculously tweaked, but different physical laws might have led to universes harboring equally awe-filled forms of energy, cooking up anthropic arguments of their own. Editors' note: Two other noteworthy books on religion by scientists have appeared recently: E. O. Wilson's The Creation: A Meeting of Science and Religion (W. W. Norton, 2006) and Joan Roughgarden's Evolution and Christian Faith: Reflections of an Evolutionary Biologist (Island Press, 2006). The Editors Recommend This Dynamic Planet: World Map of Volcanoes, Earthquakes, Impact Craters, and Plate Tectonics Smithsonian Institution, USGS and U.S. Naval Research Laboratories, 2006 Another new edition of a classic is this map, which shows the dynamic plate tectonic processes that shape the planet. All elements of the updated map are digital, and an interactive version is at www.minerals.si.edu/minsci/tdpmap. The site is somewhat slow, but the enormous amount of data at your fingertips is worth the patience required. You can make your own regional map, for example, by choosing the layers of information you want (volcanoes, plate motion, latitude and longitude, and so on). The one-by-1.5-meter paper version is a bargain at $14.
