The natural world might be reverence - inspiring , but that ’s not to say that it does n’t share similarities with the technical world that we inhabit . In fact , as biologist have come to look at beast in unaired detail , they ’ve learn that some of them have been using basics of technology — that we now take for granted — all along . Here are five of our best-loved creatures that have evolved into biologic machines .
Beetles That Screw
The weevil tends to get a high-risk imperativeness for damage crops and feasting on our food — but biologically speaking , they ’re in reality a flake love up . Literally . Take a airless look at the Trigonopterus weevil and you ’ll find that its branch are unlike those of any other creature : they’reactually do it into its torso . The top part of each leg is tie to a modest part called the trochanter . In number , the trochanter is screwed into a part holler the coxa , which is similar to a pelvis . It intend the join of the joint is entirely different than a human ’s , devote them strong leg that twine with incredible ease — pure for the climbing that the bugs attempt .
Planthoppers With Gears
Just lately , a squad of biologists from the University of Bristol , UK , discovered that the adolescent issus — akind of planthopper — uses an ingenioussystem of natural gearson its pegleg to leap higher and faster than you could ever stargaze of . When we jump , we depend on our uneasy system to distinguish our legs how to stay together in a constant feedback and alteration loop . The battle of Issus , however , uses diminutive gear to interlock their legs together , so they remain safely in that position before their mind can even register what ’s extend on . The result ? The insect can hit an acceleration of 400 yard in two milliseconds flat . In equivalence , you lose awareness over 5 G . Now , the research worker even mean the legs might inspire raw types of power train for employment by us low man .

Extruding Spiders
If you ’ve ever fooled around with Play Doh or thought about how pipework are made , you ’ll probably be comfortable with the concept of extrusion : The procedure used to make object of a fixed fussy - sectional profile by pushing material through a die . Well , it turn over out that spiders got there well before us . Whenthey birl their silk — indite primarily of a protein called fibroin and bound together by a sticky protein call sericin — they secrete the proteins , initially in liquid form , which then harden . Crucially , the silk keeps come as the filament is drawn away from the body . A wanderer apply its body weight to squeeze out the stuff — strictlypultrusion , yes , bookworm — but the whole operation is exactly the same as that used in manufactory the whole globe over .

Bacterial Power Boats
It ’s not just bounteous insects that have evolved into machines , either : Take a look at some bacteria under a microscope , and you might surprise at what you see . The bacterial scourge , for example , is one of the most complex piece of biological machinery to ever be discovered — a variety of microscopic tycoon boat . New Scientist explains how it works :
The heart of the flagellum is the basal body ; fundamentally a circular motor embedded in the bacterial cell bulwark . The motor has a serial of anchor ring , each about 20 nanometer in diameter , with a pole inside that is free to rotate a full 360 degrees . sequester to the retinal rod is a curved “ hook ” protein linked to a long whiplash - alike fibril . This filament is 5 to 15 micrometres farseeing and made of thousands of repeating units of the protein flagellin . The motor is powered by the flow of atomic number 11 or hydrogen ions across the cell rampart .
In fact , when ion flow , this fiddling thing can spin around at speeding of up to 1,000 rotation per minute . That ’s more than some wrecked old cars can manage .
The Crocodile’s Cogs
From small to tumid : While it seems improbable , crocodiles do n’t just have one curing of teeth at their disposal . obscure away in the cardiovascular organisation of these large reptilian are a serial publication ofcogs that can be used to help amuse blood line . extra valve , powered by underlying cogs , are able-bodied to divert blood aside from the crocodile ’ lungs to their bodies , controlled by the amount of adrenalin in the bloodstream . It ’s a mechanized variant of ashunt — a aesculapian term for a twist that allows corporal fluid to be redirect — and it means that the crocodile can make more efficient use of its stemma look on the place it ’s caught up in .
