Just how can the dragonfly perform its energetically-demanding aerial acrobatics—flying backwards or forwards, fast, slow or hovering—and remain airborne for such extended periods?
The answer, in part, is that it...

ping!
I think engineers can learn a lot from insect mechanics. I have always been fascinated by the “daddy long legs” spider, how they control those long legs, about 20 times the size of their bodies. The control systems must be ingenious.
Thanks for the ping!
Some cool info on dragonfly wings....check.
With this new insight into the aerodynamic efficiency of out-of-phase flapping, engineers hope to apply it in the next generation of flapping micro air vehicles.
I seriously doubt anyone's REALLY looking at a "flapping" aircraft. MUCH easier to have a rotary mechanism than a flapping mechanism.....I'd guess it's easier on the aircraft too. Just thinking of all that stress on an attachment point...
It defies reason to suggest that an energy-efficient aerial acrobat such as the dragonfly was not intentionally, and intelligently, designed.
False conclusion Dr., but good use of the word "design"...
In fact, the researchers involved in this aerodynamic efficiency study apparently recognized the difficulty their finding presents to the widely-accepted evolutionary scenario, which posits that four-winged dragonflies arose long before (i.e., are “more primitive” than) the two-winged Diptera
BWAAAAAAhahahahaha......stupid Dr. should have studied some entomology. Dipterans' ancestors USED TO HAVE 4 wings but their hind wings developed into haltares....hint.....evolution.
Surely it makes much more sense to say that four-winged dragonflies and two-winged flies were each designed to do what they do do, and what they do do, they do do well!
Surely, Dr., it makes more SCIENTIFIC sense to say that dipterans, hemipterans, anisopterans, zygopterans, tricopterans, etc.... evolved or co-evolved from common 4-winged ancestors.
The Creationist thing to say is "God did it."
And yet, you come by each thread, sniffing and inhaling deeply of the Crap, filling your nostrils with the tainted scent from the Crap, almost as if you really, really liked the smell.
: )
Or, in reality, just pointing out where others might not wish to step.
(or in your case, fall face first into..)
If you want to see the feathers fly, just say ‘a God’, instead of ‘The God’.
What empirical evidence does the author cite to support this assertion?
I have a collection of Odonata. Some can only be speciated by the venation pattern of the wing. Beautiful creatures that spawn from some of the ugliest macroinvertebrates that ever crawled through the pond.
That could be used as a nice analogy... (fill in the blank style).
They aren’t partial to presenting evidence over editorialization.
Then why do you step right into the middle of it? Bored?
Doesn't that contradict your tagline?
Maybe the author is citing the fact that they have survived for like 250 million years, unchanged. I'd say that was pretty good evidence.
Here’s something to ponder.
Caterpillars are wormlike fuzzy creatures that climb around plants and eat their leaves. They wrap themselves up in a cocoon and, in a wink of an eye, totally EVOLVE (metamorphosis) into an entirely different (in just about every way one can think of) creature. How is it possible that a creature can totally ‘transform’ it’s body????
250 million years? What are you, some kind of old-earther. Don’t tell me you’ve bought this fraudulent science that claims to prove the earth is millions, yea, even billions of years old. Blasphemer. Infidel!
(/sarc, although I hope it isn’t really necessary to say so)
All exoskeletal creatures molt to grow. The transition comes as they reach sexual maturity - you must admit that you don’t look the same now as you did when you were a toddler.
Evidence for what?
