There are scientists, who propose startling new theories about the origins of life on earth to their colleagues:
Space radiation preferentially destroys specific forms of amino acids, the most realistic laboratory simulation to date has found. The work suggests the molecular building blocks that form the "left-handed" proteins used by life on Earth took shape in space, bolstering the case that they could have seeded life on other planets . . . .There are philosophers (such as Daniel Dennett, author of Darwin's Dangerous Idea) who attempt to explain the distinction between science and quackery to lay readers:
The team believes a special type of "handed" space radiation destroyed more right-handed amino acids on the icy dust from which the solar system formed. This dust, along with the comets it condensed into, then crashed into Earth and other planets, providing them with an overabundance of left-handed amino acids that went on to form proteins.
Intelligent design advocates, however, exploit the ambiguity between process and product that is built into the word "design." For them, the presence of a finished product (a fully evolved eye, for instance) is evidence of an intelligent design process. But this tempting conclusion is just what evolutionary biology has shown to be mistaken.And then there are morons, who pander to imbeciles:
Yes, eyes are for seeing, but these and all the other purposes in the natural world can be generated by processes that are themselves without purposes and without intelligence. This is hard to understand, but so is the idea that colored objects in the world are composed of atoms that are not themselves colored, and that heat is not made of tiny hot things.
The focus on intelligent design has, paradoxically, obscured something else: genuine scientific controversies about evolution that abound. In just about every field there are challenges to one established theory or another. The legitimate way to stir up such a storm is to come up with an alternative theory that makes a prediction that is crisply denied by the reigning theory - but that turns out to be true, or that explains something that has been baffling defenders of the status quo, or that unifies two distant theories at the cost of some element of the currently accepted view.
To date, the proponents of intelligent design have not produced anything like that. No experiments with results that challenge any mainstream biological understanding. No observations from the fossil record or genomics or biogeography or comparative anatomy that undermine standard evolutionary thinking.
Instead, the proponents of intelligent design use a ploy that works something like this. First you misuse or misdescribe some scientist's work. Then you get an angry rebuttal. Then, instead of dealing forthrightly with the charges leveled, you cite the rebuttal as evidence that there is a "controversy" to teach.
Note that the trick is content-free. You can use it on any topic. "Smith's work in geology supports my argument that the earth is flat," you say, misrepresenting Smith's work. When Smith responds with a denunciation of your misuse of her work, you respond, saying something like: "See what a controversy we have here? Professor Smith and I are locked in a titanic scientific debate. We should teach the controversy in the classrooms." And here is the delicious part: you can often exploit the very technicality of the issues to your own advantage, counting on most of us to miss the point in all the difficult details . . . .
In short, no science. Indeed, no intelligent design hypothesis has even been ventured as a rival explanation of any biological phenomenon. This might seem surprising to people who think that intelligent design competes directly with the hypothesis of non-intelligent design by natural selection. But saying, as intelligent design proponents do, "You haven't explained everything yet," is not a competing hypothesis. Evolutionary biology certainly hasn't explained everything that perplexes biologists. But intelligent design hasn't yet tried to explain anything.
Drivers who pull off Interstate 10 in Pensacola, Fla., are told a far different story at Dinosaur Adventure Land. Its slogan: "Where Dinosaurs and the Bible meet!"(Thanks to Zemblan patriot J.D. for the Dino-link.)
The nearly 7-acre museum, low-tech theme park and science center embodies its founder's belief that God created the world in six days. The dinosaurs, even super carnivores such as T. rex, dined as vegetarians in the Garden of Eden until Adam and Eve sinned — and only then did they feast on other creatures, according to the Christian-based young-Earth theory.
About 4,500 years after Adam and Eve arrived, the theory goes, pairs of baby dinosaurs huddled in Noah's Ark, and a colossal flood drowned the rest and scattered their fossils. The ark-borne animals repopulated the planet — meaning that folk tales about fire-breathing beasts are accounts of humans battling dinosaurs, who still roamed the planet.
Kids romping through the $1.5-million Florida theme park can bounce on a "Long Neck Liftasaurus" swing seat; launch water balloons at a T. rex and a stegosaurus, and smooth their own sandbox-size Grand Canyons, whose formation is credited to the flood. A "fossilized" pickle purports to show that dinosaur bones could have hardened quickly. Got an upcoming birthday? Dinosaur Adventure Land does pizza parties.
"Go to Disneyland, they teach evolution. It's subtle; signs that say, 'Millions of years ago' " said evangelist Kent Hovind, the park's founder. "This is a golden opportunity to get our point across."
Carl Baugh opened his Creation Evidence Museum in the 1980s near Dinosaur Valley State Park in Glen Rose, Texas, where some people said fossilized dinosaur tracks and human footprints crisscrossed contemporaneously. The Texas museum sponsors a continuing hunt for living pterodactyls in Papua New Guinea. Baugh said five colleagues have spotted the flying dinosaurs, "but all the sightings were made after dark, and we were not able to capture the creatures."
Organizers at Creation Research of the North Coast in Humboldt County, Calif., dream of building their own reptile park but lack funding and acreage. So do leaders at Project Creation in Mount Juliet, Tenn., who would need to raise about $1 million to assemble 30 to 50 pterodactyl and brachiosaur replicas to mingle with live chickens and goats . . . .
"We like to think of [dinosaurs] as creation lizards, or missionary lizards," said Frank Sherwin, a museum researcher and author . . . .
Creationists defend their dinosaur museums and attractions as a way to teach a grander purpose: If the Bible's history is accurate, then so is its morality.
"If [evolutionists] convince people that dinosaurs are exotic, strange creatures, they've won right there, and the Bible looks like a book of Jewish fairy tales," said Sean Meek, executive director of the Tennessee group Project Creation.
