They have been isolated from Earth’s surface for several million years because analyses of the water that they live in showed that it is very old and has not been diluted by surface water. It may also have acquired genes from a species of archaea by horizontal gene transfer.

The archaeal genes present in the D. You must be logged in to post a comment. Recently, scientists have lowered their estimates of the number of microbes that they expect live deep underground. It was detected in bore holes 2, feet meters beneath the surface of California’s Death Valley.

It has somehow evolved to do without the sun or oxygen. The hydrocarbons in that environment do not come from living organisms. Previously, scientists have looked to organisms that live along hydrothermal vents as analogues to what we might find on Europa, which is an ocean world covered in a layer of ice that is also suspected of having hydrothermal vents. The bacterium has transporters for both sugars and amino acids, which can be used a carbon source if they are available in the environment.

At MP, where biodensity is low, carbon is fixed from inorganic sources…. Its complete intolerance of oxygen suggests long-term isolation.

Scientists suggest it could have made its way to the surface in the mine’s water, and hitched a ride around the world on currents of air.
