Origin of microbial life and the evidence supporting current views of microbial evolution.

Introduction:

Fossils can be defind as the remnants or traces of ancient living entities that got preserved due to certain natural processes. The very first evidence of fossilized cells in the geological rocks appeared 3.8 billion years ago. Early microfossils from more than 2 billion years ago were made up of living cells. Living forms of these fossils looked profoundly similar to today’s bacterial cells.
