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 todayâ€™s bacterial cells.

Discuss the possibility of life on Mars. Will extremophiles prove useful? Can you explain the upper-temperature limit to life unrelated to the stability of proteins or nucleic acids? How influential is microbial activity on the geological processes of mineral formation and deposition compared to biological processes? Can you argue both sides? What are the challenges and advantages of the use of extremeophiles in industrial or bioremediation applications?
