Abstract
Like other living entities, viruses substantially resemble the parent during their replication, but can change to give rise to new types or “strains”. This inherent variation enables viruses to adapt to new and changing situations. Over longer periods of time new viruses arise, and there must have been a time at which the archetypical virus arose. The origin and factors involved in the evolution of plant viruses are discussed in this chapter.
