The Superbugs Theory


Methanogenic Archaeon (primitive bacteria)

The Superbugs Theory Suggest that, because of the discovery of a vast amount extremophiles underground, life may have originated safely underground as tiny microbes in the extreme environment.Chicago geologist Edson Baston first proposed this theory in 1920

Superbugs can live in extreme conditions. They could exist as the following:

Thermophiles (heat lovers)
Halophiles (salt lovers)
Methanogens (make methane)

They are considered to be chemotrophs (chemosynthetic/chemosynthesis) because they got their energy from chemicals. These superbugs can live 4 km (2.5 mi) underground and 7 km (4.3 mi) below ocean floor. They can sustain temperature up to 170 C (338 F).

The populations of superbugs are more than 1 billion per cubic centimeter @ the surface and about 10 million deep down. They increases at deeper depths.

Advantages for Superbugs theory

1.      Micro-organisms underground are not affected by the bombardment of earth on the surface

2.      No ultraviolet radiation when underground

3.      No dust from volcanoes underground

4.      No climatic variations underground

5.      More raw materials necessary for life (reducing gases)

a.       Hydrogen

b.      Methane

c.       Ammonia

d.      Hydrogen Sulfide

e.       Other minerals

6.      Energy available underground

a.       Maximized @ 100 to 150 C

b.      Gain energy from fabricating compounds

7.      The archaea has evolved the least, meaning earliest form of life

8.      Subsurface has changed far less than surface (same primitive organisms)

9.      Microbes can make energy from chemicals (Chemotrophs)

Microbes the are believed to have risen from ground and adapted as surface dwellers.
