There’s an Entire Living World Beneath Your Feet, And It Shouldn’t Exist

While you may think there isn’t any life deep within the Earth, scientists have found a vast ecosystem of microbes that is causing scientists to rethink where life can exist and how it is evolving.

Yes, according to ScienceDaily, scientists have found that microbes exist kilometers deep within the Earth. What is even more surprising is the fact that they have been found in areas that have extreme pressures and limited nutrients. Unbelievable? Well, that’s what Science says!

Life in Extreme Chemical Conditions

One of the most surprising elements of this discovery is the chemical environment in which these microbes live. The pH level of the rock and the fluids around it can reach as high as 12 in certain areas. This is actually a very high pH level and is not favorable for any living organisms.


However, the microbes continue to perform their functions through alternative metabolic processes that do not require any source of energy from the sun.

Research suggests that these microbes metabolize methane and sulfate compounds and thus produce energy through these processes. This process allows for new forms of metabolism that were previously unknown. Research conducted in Yellowstone also indicates that earthquakes can introduce new fluids and fractured rocks into deep subsurface environments, causing sudden bursts of chemical energy that can be utilized by microbes to grow and multiply.

Earthquakes can trigger sudden changes in the populations of microbes and water chemistry, indicating that the deep biosphere is not static but constantly evolving in response to geological activity, as reported by ScienceDaily.

Another significant finding is from the ocean floor, where scientists have found microbial communities within porous rock structures created by ancient lava flows. These microbes use carbon dioxide as a source of energy, as per ScienceDaily.

According to a study published in ScienceDaily, it seems that microbes are able to alter rock structures to create a more suitable environment for habitation.

A Link to Earth’s Earliest History

Perhaps the most intriguing aspect of this discovery is the connection it bears with Earth’s ancient history.

The discovery of life in the deep subsurface biosphere has significant implications for our understanding of life on Earth and potentially elsewhere in the universe. So, these microbes prove that life can thrive in the absence of sunlight, in extreme chemical conditions, and under extreme pressures. This greatly increases the potential for discovering life on other planets in our universe.

Can you imagine what was once thought of as lifeless rock is now known to be a biological system? Yes, and to our surprise, it has been working quietly away under our feet. Maybe, with the growing advancements, we’ll get closer to what’s unexplored one day.
