The first evolved mobile genetic elements were RNA based viroids.  These circular non protein coding elements gave rise to ribosomal RNA, transfer RNA and messenger RNAs. They probably arose from a GNA world after a Montomorrilate and Iron Sulfur world and assisted by a PAH world.<\/h3>\n

Viroids gave rise to a Peptide-RNA World  that included RNA dependent polymerase elements such as Leviviridae and Retroviridae.  Subsequent DNA elements arose and diversified into life forms including Plasmids, transposons, and multiple Viral RNA\/DNA families.<\/h3>\n

The network of mobile genetic element evolution can be traced by the capsid, replicative, integrative, and ribozyme structural domains.<\/h3>\n

Major astrobiological events are equated with the emergence of hybrid mobile genetic element families.<\/h3>\n
