Abstract
Satellites, like their helper viruses (HV), vary genetically because, during replication, mutations (sensu lato, i.e., base substitutions, insertions, deletions, inversions, recombinations) are introduced in their nucleic acids thus producing genetic variants. The frequency distribution of genetic variants in the population of an organism defines its genetic structure, which may change with time in a process called evolution. Evolution may lead eventually to the rise of new taxa, such as virus or satellite species, and one aspect of the study of evolution is to clarify the origin and history of organisms and their resulting taxonomic relationships. For viruses, and satellites, this paleontological side of evolutionary studies relies almost entirely on phylogenetic reconstructions based on nucleotide or amino acid sequences of extant individuals of different taxa. Interesting as this intellectual exercise might be, and in spite of large methodological advances in phylogenetics, it abounds with pitfalls, which deepen the farther back in time reconstructions attempt to dig
