Abstract
The lecture covers three main topics: (i) Viruses: properties, place in the living world, and possible origin; (ii) Molecular basis of viral variability and evolution; and (iii) Evolution of viral pathogenicity and emerging viral infections.
Keywords: Selfish genetic elements, replication, transcription, mutation, recombination, plasmids, pathogenicity, fibroma/myxoma virus, influenza virus, SARS-coronavirus, human immunodeficiency virus
