viruses from bacteria through so-called \u201cregressive\u201d evolution. Most
recognized is the third hypothesis that the viruses originate from cellular
components similar to plasmids. Once appeared they have evolved from
simple to more complexly organized forms, and some of them could have a
polyphiletic way of evolving thus creating the enormous \u201cVira Kingdom\u201d.<\/p>\n\n\n\n
