Experiments, as well as insights, that shaped the controversy over the theory of spontaneous generation. Introduction: The very first evidence of fossilized cells in geological rocks appeared 3.8 billion years ago. Early microfossils that arose more than 2 billion years ago were made up of living cells. The cell is the smallest or basic unit of life and it is able to perform various functions that are necessary for survival.
