a plant-hopping insect found in gardens across Europe - has hind-leg joints with curved cog-like strips of opposing 'teeth' that intermesh, rotating like mechanical gears to synchronise the animal's legs when it launches into a jump.

The finding demonstrates that gear mechanisms previously thought to be solely man-made have an evolutionary precedent. Scientists say this is the "first observation of mechanical gearing in a biological structure"......


Gears evolved?? Really?????

@gungasnake,
When you show your ignorance of biological systems you like to do it at the top of your lungs dont you?
Microscopic "ratcheting motors" have been well documented in the literature for years. Some biomechanics dudes have even planned to use bacteria with these wheel drives to power little micro apparati

Quote:
Bacteria swim through fluids by using a number of rotary motors embedded in their cell walls to drive thin helically shaped filaments in a clockwise or anticlockwise direction. Researchers have used this motion to propel micro-structures but, as the bacteria movement is random, it is difficult to control without the addition of chemicals.
Now, Roberto Di Leonardo and colleagues at the University of Rome "La Sapienza" have shown how to exploit the motion of E. coli without controlling the bacteria in any way. They exploit the fact that a collection of bacteria immersed in a liquid represents a non-equilibrium thermodynamic system by virtue of the self-propulsion of the bacteria. This non-equilibrium system, they say, should confer ordered motion on an asymmetrically shaped object, in contrast to the random, Brownian motion, that thermal gas molecules would generate.

Formerman actually believes gears could evolve, sort of sad.

I mean, somebody could find an insect with a six-speed transmission and two clutches (entry and exit) just like the new Alfa Romeo and, apparently, there would still be die-hard evolosers claiming it had evolved....

@gungasnake,
thats just because youre as dim as a burnt-out light bulb

1It cannot be ID because , since a "Gear assembly" (meaning its got teeth and rotates) has long been known on many microorganisms, the rule of evolution is proven
"take something youve got and modify it to do something else"

2. It IS evolution because a higher order of organism has adopted something already in use by some organism that lies in the genetic lower rung of this bug and modified it to perform a different role (allowing the little bug to jump strait)


Gears , as a human mechanical device were first reported in Greek writings, Im not sure about clutches, transmissions , paddle shifters, Transaxles, and All Wheel Drive. (I dont think this bug has any of that either)

But Ill give you that , had some deity made bugs with gears, hed have given them some greater mechanical advantage for jumping, like that in a grasshopper, flea, or katydid's methods of hurling.


WAX _ON, WAX_OFF.

@farmerman,
there are many many solutions to "jumping" in the animal and p[lant woprld. The most studied in recent years had been the extreme jumping ability of the common flea.

http://blogs.britannica.com/2011/02/jumping-fleas-biomechanics-wingless-existence/

Biomechanix studies on fosil short faced bears also showed how they developed a unique "Tongue and grrove" fixture on their hips and shoulders to allow them to achieve good running speeds(with the biological cost being an inability to "turn on a dime"

I think the reason our gunga is so closed to deductive reasoning based on evidence is because he really NEEDS his worldview to direct his life.
Many of us had easily passed through that stage after much careful analysis of facts.

@farmerman,
Well, farmer, there are even a few more who need this worldview:
Quote:
What we see in this discovery is another marvelous design by a Creator who reports in His Word that He created each kind of living thing within the first six days of earth’s existence about 6,000 years ago. He created living things able to reproduce variety, but only within their created kinds. Nothing we see in observable biology is inconsistent with our Creator’s claims in His Word.

Which it tantamount to saying "Nothing we see in observable biology is inconsistent with All-Powerful Magic". And Duh, how could anything be inconsistent with unlimited poofism. I mean really, why do they even waste time writing stuff like that. It's a waste of ink, or pixels or photons or whatever.

Here's a Swiss watch mechanism:

Have at it, Formerman: let's hear how that thing evolved...

@gungasnake,
Whenever honest inspections of gunga's latest brainfarts are made, gunga always tries to divert attention from the main issue, as he did just now.

Since Ive successfully traced the occurence of "cogged" biomechanical systems in simpler life forms perhaps we should compare genomic data between the earlier v the "derived" structures to see the relationship of the associated genes .

Also, are you aware gunga that there is a minor fossil record of this species of insect

@farmerman,
If a response isn't posted within the next couple of hours - we will never know!

Since, Joel 2:30-31:
Quote:
I will show wonders in the heavens
and on the earth,
blood and fire and billows of smoke.
The sun will be turned to darkness
and the moon to blood
before the coming of the great and dreadful day of the Lord.
