  title={Molecular evolution of viruses: An interim summary},
  author={Yechiel Becker},
  journal={Virus Genes},
The origin and molecular evolution of viruses in this issues is dealt with at two levels: (1) tracing the past evolutionary pathways of viruses belonging to RNA virus families, retroviruses, and small and large DNA viruses; (2) tracing current changes in the RNA and DNA viral genomes that lead to the evolution of new virus mutants. In this interim summary, a time scale for the evolutionary processes is given, based on the accumulated published knowledge concerning the postulated origins of life… CONTINUE READING
