Covid-19 -  A  Natural Phenomenon Viruses are not living things ; They are complicated assemblies of molecules, including proteins, nucleic acids (DNA & RNA), lipids and carbohydrates ; But on their own they can do nothing unless or until they enter in living cells ; Where they can replicate themselves & mutate in the host cells ;   Viruses are continuously changing as a result of genetic selection ; They undergo subtle genetic changes through mutation and major genetic changes through recombination . Mutation occurs when an error is incorporated in the viral   genome ; Recombination occurs when   co-infecting viruses exchange their genetic information creating a new type i.e. novel virus ; In prehistoric times human beings were hunter-gatherer ;   Apart from hunting their prey animals, mainly big herbivorous animals, their interaction with the animal world was minimal ; But along with growth of civilization they started domestication of animals, forming dairies, piggeri
