The extent to which viruses and their hosts codiverge remains an open question, given that
numerous cases of both “cospeciation” and horizontal switching have recently been …

RNA viruses provide unique insights into the patterns and processes of evolutionary change
in real time. The study of viral evolution is especially topical given the growing awareness …

The study of RNA virus evolution has blossomed over the last 20 years. Despite the
emergence of this new discipline, there has been little active debate over perhaps the most …

Geoghegan and Holmes describe the history of evolutionary ideas in the study of viruses,
showing that two different approaches to studying virus evolution—the comparative and the …

Viral quasispecies are closely related (but nonidentical) mutant and recombinant viral
genomes subjected to continuous genetic variation, competition, and selection …

RNA viruses are excellent experimental models for studying evolution under the theoretical
framework of population genetics. For a proper justification of this thesis we have introduced …

A new word, phylodynamics, was coined to emphasize the interconnection between
phylogenetic properties, as observed for instance in a phylogenetic tree, and the epidemic …

This chapter documents that RNA viruses have been known for over a century to be
genetically variable. In recent decades, genetic and molecular analyses demonstrate that …

Several factors play a role during the replication and transmission of RNA viruses. First, as a
consequence of their enormous mutation rate, complex mixtures of genomes are generated …

RNA viruses are the main agents of emerging disease. To understand how RNA viruses are
able to jump species boundaries and spread in new hosts it is essential to determine the …
