ABSTRACT
Recent events of the viral catastrophe have shown the rapidity of spread of new disease through emergence of virulent strains. Proper control measures can be developed only through understanding the evolution of virulence in RNA viruses. To understand the evolution of this novel Coronavirus, COVID-19, it is imperative to delineate the evolution of RNA, its transformation into first life forms, the steady and continuous evolution and emergence through modification in their genome and nevertheless the natural selection. This review will throw light on these aspects to understand the possible origin of COVID-19 to control and eradicate this viral outbreak.
