'Zombie' bacteria found deep beneath the Earth

Scientists have revealed that an incredibly large amount of life exists in our planet's deep subsurface.
The discovery was announced following a ten-year study by an international team of researchers who examined samples retrieved from mines and boreholes up to 3 miles beneath the surface.

This remarkable 'deep biosphere' contains up to 23 billion tons of living organisms - that's the carbon equivalent of up to 385 times the entire human population of the Earth.

It is now believed that as much as 70% of all the Earth's bacteria and archaea live in the subsurface.

The find is particularly intriguing because it opens up the possibility that life on our planet started deep inside the Earth and then later migrated towards the surface.

It also suggests that similar life forms might exist beneath the surface of other worlds such as Mars.

"Even in dark and energetically challenging conditions, intraterrestrial ecosystems have uniquely evolved and persisted over millions of years," said geomicrobiologist Fumio Inagaki.

"Expanding our knowledge of deep life will inspire new insights into planetary habitability, leading us to understand why life emerged on our planet and whether life persists in the Martian subsurface and other celestial bodies."

The Hopi may have some sort of myth that "we" emerged from underground, but they could not have known anything about bacteria living in deep subsurface.  Just sayin'.

I would be careful makimg assumptions. When speaking of history we cant always be sure what other people know. If someone really did climb up a tree to get out of the cave in the ground im sure they know plenty about whats in that cave. They also have a number of how many planets are seeded with humans. I think its about 187,000. Before that i couldn't concieve of how natives would even be aware of such a high number tbh. But we can never be aware of everything others have been aware of, only listen to thier stories and learn from it. My point also wasn't about whether the hopi were aware of b... [More]

Actually i tested a bit higher and i dont think they were aliens i think its people doing it but yeah laugh all you want  doesnt change the facts. Also hardly relevant to hopi legends and the fact that the earth is full of life. People get so hung up when i toss different ideas in there. In thier legends they have an exact number of how many planets they believe humans inhabit in this galaxy. From my recollection it was 187,000 something. When i refer to things like this im just pointing out that not all history is fake or unimportant. Myths like this come from somewhere and sometimes should b... [More]

A high IQ means nothing if you can't do anything with it. Common sense is a better gage of actual intelligence.  From what I've seen so far. Common sense is on the near extinct list.

Do you expect me to do tricks for you? I have no use for gages. I'm much more interested in the topic. Its led me to learn how fascinating eels are. They are subterranean creatures actually and travel through aquifers, mud and underground. They can take oxygen in through thier skin so they dont even have to breathe down there. They often appear in freshly dug wells from underground and also have the ability to climb over land. If they can do it imagine what's in the more cavernous areas down there. Not too mention they travel the ocean to spawn and coordinate with groupers to hunt. Apparently ... [More]

"My IQ is over 160!!!1!" -thinks water filters are illegal- Something isn't jiving here...   On the topic of "IQ testing" - IQ tests are a load of BS, especially ones found online. https://www.medicaldaily.com/study-confirms-iq-tests-do-not-accurately-predict-intelligence-243971
