quicker chameleon tongue from in fighting jet plane
Text books zoology explain that chameleon ballistic tongue is braced by a thin accelerator muscle (accelerator). this muscle is when depress downwards in tongue bone, shaped stiff cartilage in the middle of tongue, wrap up it. but, in a watchfulness that approved to published by scientific magazine proceedings of the extravagant society of London (series b), two morphology experts learn habit eats chameleon finds elements other related to this animal tongue whisk.
second this Dutch researcher, jurriaan de groot from leyden university, and champion van leeuwen from university wageningen, take tall speed x-ray movies, that is 500 frames per second, in order to delve to how chameleon tongue works when catch prey. this movies shows that chameleon tongue end experiences acceleration 50 g (g = gravity constant). this acceleration five times bigger than that reachable by a fighting jet.
This researchers operates tongue network and find that accelerator muscle both at all enough strong to produce style that need this is alone. With canvass chameleon tongue, they find existence at least 10 slippery packages, up to moment that is not yet known, between accelerator muscle and tongue bone. These packages, cling to tongue bone at proximate the end with mouth, perceived to contain fibers protein connected spiral. These fibers are solid and change when does accelerator muscle shrink and keep energy likes one rubber ribbon that depress. When achieve tongue bone round end, tight packages and lengthways this is concurrently derail and shrink with strength and throw tongue. as soon as these fibers derails from tongue bone, packages mutual separate self like tubes a telescope, and therefore tongue achieves reach so far. van leeuwen say, “this telescopic catapult. ”
This catapult has characteristic other very jazzy. tongue end takes empty form at the (time) of strikes hard prey. When throwed, this tongue can stick out as far as six when does rest in mouth, and twice long the body self.
Clearly those packages mutual linked in these chameleon tongue never explainable follow evolution. In that word, let us raise questions next:
1. How each this package being revolutionized to the place true?
2. How does tongue grow in such a way long?
3. How does accelerator muscle appear?
4. How does packages harmonization the gesture so that make tongue achieve the maximum long?
5. how does packages growth ability to “long
Tubes basin self teleskop”?
6. How does animal merger all this parts after “meluncurkan” tongue?
7. if this tongue is got as character beneficials evolution process consequence, then why is character superior this not bloom in animals other and why does animals other not has manner hunt same?
8. how does chameleon (or animal that assumed the transition great grand father) survive when all systems complex this be guessed slow berevolusi? (2)
