Homoplasy in genome-wide analysis of rare amino acid replacements: the molecular-evolutionary basis for Vavilov's law of homologous series

Igor B Rogozin, Karen Thomson, Miklós Csürös, Liran Carmel, Eugene V Koonin Biology Direct 2008, 3:7 (17 March 2008)

Abstract | Full text | PDF | PubMed |  Editor’s summary

Homoplasy denotes the same (parallel) mutations occurring independently in different lineages. It is a scourge of phylogenetic methods. Here, however, it is shown that homoplasy is also an interesting evolutionary phenomenon. Homplasy seems, at least, in part, to underlie the so-called homologous series of phenotypic variation occurring in different, particularly, closely related lineages, an effect first described by the famous Russian geneticict Vavilov some 90 years ago.
