I'll help Hedge out with a bit of Daniel Dennet
The theory of evolution diminishes the best reason anyone has ever suggested for believing in a divine creator.
He doesn't worry about the theory of gravity or thermodynamics and radioactivity or germ theory or the laws of entropy. He's happy to fly through the air at 350 mph in a metal box designed by science and technology and type words into a machine that can send them all over the world in the blink of a bats eye - but this one thing science has got completely wrong.
Weird ain't it?
So who really deserves the credit for these designs?
IN RECENT years scientists and engineers have, in a very literal way, allowed plants and animals to instruct them. They are studying and mimicking the design features of various creaturesa field known as biomimeticsin an effort to create new products and improve the performance of existing machines.
What have aircraft designers learn from the humpback whale?
A great deal it seems.
An adult humpback weighs about 30*tonsas much as a loaded truckand it has a relatively stiff body with large winglike flippers. This 40-foot-long [12*m] animal is remarkably agile under water. For example, when feeding, a humpback may swim in upward spiraling circles beneath a prospective meal of crustaceans or fish, all the while blowing a stream of bubbles. This bubble net, as small as five feet [1.5*m] in diameter, corrals the creatures at the surface. The whale then snaps up its tidy meal.
What particularly intrigued researchers was how this stiff-bodied creature turns in what seem to be impossibly tight circles. They discovered that the shape of the whales flippers holds the secret. The leading edge of its flippers is not smooth, like an aircrafts wing, but serrated, with a row of protruding bumps called tubercles.
As the whale slices through the water, these tubercles increase lift and reduce drag. How? The journal Natural History explains that the tubercles make the water accelerate over the flipper in an organized rotating flow, even when the whale is rising at very steep angles. If the flipper had a smooth leading edge, the whale would be unable to make such tight rising turns because the water would churn and eddy behind the flipper and cease to create lift.
What practical applications does this discovery promise? Aircraft wings based on the design would evidently need fewer wing flaps or other mechanical devices to alter airflow. Such wings would be safer and easier to maintain. Biomechanics expert John Long believes that someday soon we may well see every single jetliner with the bumps of humpback whale flippers.
Mimicking Seagulls Wings
Of course, we already know, aircraft wings already mimic the shape of birds wings. However, engineers have recently taken this mimicry to new heights. Researchers at the University of Florida, reports New Scientist, have built a prototype remote-controlled drone with a seagulls ability to hover, dive and climb rapidly.
Seagulls perform their remarkable aerobatic maneuvers by flexing their wings at the elbow and shoulder joints. Copying this flexible wing design, the 24-inch prototype drone uses a small motor to control a series of metal rods that move the wings, says the magazine. These cleverly engineered wings enable the small aircraft to hover and dive between tall buildings. The U.S. Air Force is keen to develop such a highly maneuverable craft for use in searching for chemical or biological weapons in big cities.
Does it seem logical then, for highly trained researchers who crudely mimic systems in nature to solve difficult engineering problems to attribute the genius of devising the original idea to unintelligent evolution?
If the copy requires an intelligent designer, what about the original?
Really, who deserves more credit, the master artist our Creator or the student who imitates his technique?
