Scientists show a huge lifestyle of life Life under the ground


The land is not the home you are thinking about. Much lower than the places we do not live, planet that appears with a dark biosphere; deep of subsidiary animals that scientists just want to; begin to understand.

Audited throughout this habitat, some of the world's deepest and oldest organisms succeed in places where there should be no life, and in a new research , scientists have a This darker case of the world is considered as ever before.

"Ten years ago, we had only invested some of the sites – the types of places we would expect to get a living," a & # 39; Microbiologist Karen Lloyd explains from the University of Tennessee at Knoxville.

"Now, thankful to very deep sampling, we know that we can find it well in every place, although it is clear that sampling only part of a non- sure of the deep bodphere. "

There is a good reason why sampling is still the early stages.

In a preview of results from a 10 year collaboration with over 1,000 scientists, Lloyd and other researchers with the Deep Carbon Theater (DCO) deep bundle – the living area beneath the Earth's surface – which includes a number between 2 and 2.3 billion cubic kilometers (0.48 to 0.55 billion cubic miles).

That's almost twice the size of all the world's seas – another huge natural environment that is not widely defined by humans.

And just like the seas, the deep biosphere is a plentiful source of animals with a total number of 15 to 23 billion tonnes of shoulder (between 245 and 385 times more than a majority of people on the surface ).

The conclusions, which represent many of the surveys carried out at hundreds of sites worldwide, based on microscopic surveys drawn from sediment samples found for 2.5 kilometers (1.6 miles ) underground, and drilled from landfill mines and excavation more than 5km (3.1 miles) deep.

Unlocked at these depths, two types of pipes (bacteria and archaea) affect their & # 39; a deep beer, and it is estimated that they are; make up 70% of earth and archaea plants.

In terms of how many types of organisms we speak, nobody knows.

But scientists are looking at the Carbon Deep sciences that millions of specific types are waiting to be discovered and marked by these methods.

"Investigating deep sub-depth resembled the Amazon rainforest research", says Mitch Sogin's biologist from the Marine Biology Network at Woods Hole, Massachusetts.

"There is life in every place, and in every place there is a plentiful richness of unintended and unexpected organisms."

These animals are not just unusual for their appearance and habitat, but the right way, with lively and long-lived animals over timescales near geology, and – without sunlight – a & # 39; going to a small extent of chemical energy harvested from the surrounding cliffs.

"My most amazing thing is that there may be some organisms for millennia," said Lloyd The DefenderSouth Westerly

"They are physically active but in stasis, with less energy than we think might be possible for life that supports us."

Such results not only promote their & # 39; The idea that deeper life could be in any other place in the Undertake hidden within dark biosphere of foreign world – they also try to test our explanation of what; his life.

In a way, we will drill deeper, and beyond we Looking back in advanced history and history.

"Molecular surveys look like dark microbial situations are much more different than what we are currently seeing, and the deepest sharp lines that challenge the Carl Woese introduced a three-dimensional trespass in 1977, "Sogin is a" described in a statement.

"We may come to a decision where the earliest branching patterns could be accessible through deep research."

The results were presented to the meeting of the American Geological Union (AGU) Meeting in Washington, DC this week, and it is expected that the final DCO report will be published in October 2019.
