Why the Anti-Science Creationist Movement Is So Dangerous

They want to wipe out all the findings of hundreds of years of scientific investigation and have taken to schools, the courts and political leaders to get things done.

And then there's the direct evidence for evolution, in all its sprawling grandeur. We know evolution is true from genetic studies which show that all species share deep similarities at the genetic level. In fact, by charting which species' genomes share the same one-off mutations, we can build evolutionary trees which show the patterns of relationship between species and allow us to estimate when they branched from each other. This nested hierarchy, the pattern produced by descent with modification, binds all living and extinct species together in an unbreakable web of heredity and kinship, every bit as real as the one that connects you to your ancestors and your living relatives.

We know evolution is true from transitional fossils which preserve snapshots of evolutionary change, such as the bird-like feathered dinosaurs; the therapsids that are intermediate between reptiles and mammals; the primitive whales with legs that are ancestors of today's cetaceans; and in our own family lineage, the humanlike hominids that show how modern Homo sapiens arose from more ape-like ancestors. (Hilariously, the creationists all agree that there are no transitional fossils and that all fossil hominid species are either fully human or fully ape -- but they can't agree on which is which, exactly as we'd expect from true intermediates.)

We know evolution is true from the kludges, hacks, and jury-rigs we find in the anatomy of living things, including us -- evidence not of a wise and forward-looking designer, but of a slow, mindless, tinkering process of change, a "blind watchmaker" as Richard Dawkins famously termed it. From the useless goosebumps we get when cold or frightened, to the backward-wired human retina, to the babies occasionally born with vestigial tails, human bodies bear the indelible stamp of our species' history.

The creationists are forced to deny all this and much more besides. That's not a figure of speech: major creationist organizations and religious colleges require their faculty to sign statements promising to reject any evidence that contradicts their worldview. The official statement of faith of the group Answers in Genesis, for example, requires members to affirm that "No apparent, perceived or claimed evidence in any field, including history and chronology, can be valid if it contradicts the Scriptural record." And when people affiliated with these groups do express doubt or flirt with unorthodoxy, retribution is invariably swift and harsh.

But as laughable as the creationists' beliefs are, the creationist movement is no joke. They want to wipe out all the findings of hundreds of years of scientific investigation, erase everything we've learned about the vast and majestic history of the universe, and replace it with a cartoon version that grotesquely magnifies our own importance, treating human beings as the crowning glory of creation and diminishing the immensity of the universe to a tiny stage crafted only so that the Bible's small stories could play out on it.

Why does this matter so much to them? It's not just an arcane scientific debate: in their minds, only Christianity can produce virtue, and Christianity can be true only if evolution is false. It follows that they believe - and they've said that they believe -- that evolution underlies every moral problem they see in the world, from drug use to pornography to people voting Democratic. Tom DeLay infamously blamed the Columbine school shootings on the teaching of evolution, stating that "our school systems teach the children that they are nothing but glorified apes who are evolutionized out of some primordial soup."

The larger lesson to be drawn from this is that the religious right isn't just targeting the theory of evolution. By their own words, they can't be. They believe that a person's morality is completely determined by their factual beliefs -- that being a good person depends on believing the right things about the origin of the universe. And since they believe that all truths worth knowing have already been revealed in the Bible, it follows that science is at best unnecessary and at worst a fatal deception that leads people away from salvation. Why, then, do we need science at all?
