volcano may have helped life get down , but generally address , most people connect them with the obliteration of living . Nothing , let alone DNA , can subsist in the utmost heat and acidity of a fresh lava stream .
That ’s why , when a steel unexampled bacterial coinage was regain colonizing an subaqueous volcano shortly after it had irrupt , and consequently wipe out all other word form of life history just beforehand , the team of observe scientist were a trivial taken aback .
As reported inNature Ecology & Evolution , this particular bacterium did n’t just survive the blast , but it thrive in the apocalyptic environment afterwards , which makes it an implausibly adaptive , and extremely knotty , new species indeed .
Back in 2011 , an underwater volcano off the slide of the Canary Islands began to erupt quite explosively right through into 2012 . Lava contact temperatures of 1,000 ° C ( 1,832 ° F ) break off from the Tagoro seamount , rapidly unsex the environment . Extremely sulphuric , toxic gases saturate the waters nearby , and blast shockwaves shatter the seafloor itself .
As honor at the fourth dimension by a team led by the Polytechnic University of Marche in Italy , all variant of vegetation and brute , from the largest fish to the smallest microorganisms and plants , were annihilated . The area was bereft of animation .
Fast - forward to 2014 , and the team returned to take a feeling at the post - apocalyptic hero sandwich world . To their big surprise , the intact region had been take over by monolithic microbial mats , immense solicitation of bacterium working together . Using remotely operated vehicles , they fill samples , analyze them , and base that they were all be of a antecedently unnamed genus and specie of bacterium .

They named itThiolava veneris . “ Thio ” comes from the Greek Book for sulfur , which refers to its ability to dwell among hefty sulfur compound . “ Lava ” name to the surroundings in which it emerged , and its species name “ veneris ” is a reference to Venus , the ancient Roman goddess of beauty and honey .
The team have dub it “ Venus ’s hair ” thanks to its strand - like show .
As this bacteria thrives in its unfriendly surroundings , it is separate as a character of “ extremophile ” . It appear to use the sulfur and nitrate outburst to generate energy , and it ’s likely that the destruction of all former spirit allowed it to quickly swoop in and colonise the shattered subaquatic vent .
It ’s long been bonk that there are extremophiles in every individual hostile environment on the planet , from beneath theAntarctic Ice Sheetto within superheated , rich - sea hydrothermal vent .
However , this bacterium was establish immediately colonizing a post - eruption open , which is a relatively new phenomenon . Far from being suspicious of it , they ’re even using the volcanic heat itself to help their metabolic process operate . This mechanics , then , could even hint at how foreign life onother volcanic planets and moonscould exist .
Rather wondrous , the emergence ofT. venerisdoesn’t just show how life come up a path to keep itself going even in the event of a devastating natural catastrophe . The emergence of bacteria tends to finally brook the colonization of the area by bigger and more complex forms of life , and indeed , this is what the team observed at Tagoro .
“ A specialized and highly divers food web thrives on the complex three - dimensional habitat form by these microorganisms , ” the team mark in their subject area . “ This supply evidence that Venus ’s hair’s-breadth can aim the restart of biological systems after submarine volcanic eruption . ”
So , far from being an opportunist stealer , this special bacteria could leave the foundations for a Modern citadel of biodiversity late beneath the waves .
Could we find oneself the “ cousins ” of Venus ’s Hair on other volcanically combat-ready worlds ? Roberto Danovaro
All affair considered , there ’s a chance that this biofilm get at Tagoro resembles the very first complex dependency of life that appeared on satellite Earth all those billions of twelvemonth ago .
