Prokaryotic evolution

The term evolution means the gradual change or a transformation from a simple or primitive state to a complex or advanced state. Prokaryotic evolution is a concept that involves the evolution of the form and function of most primitive organisms (prokaryotes) through several stages and changes to form diverse life as a part of organic evolution.
