[The origin and evolution of viruses].

Nordisk medicin - 1 Jan 1990

Rødahl E

Abstract excerpt

This paper describes various hypotheses for the origin of viruses, prerequisites for the introduction of a virus into a host population, and the concerted evolution of virus and host. In general, viruses evolve through mutations and genetic recombinations. Selection pressure is exerted by various host defence mechanisms and possible ways of virus transmission. The virus variants showing a high reproduction rate...
