n. pl. phy·log·e·nies
1. The evolutionary development and history of a species or trait of a species or of a higher taxonomic grouping of organisms: the phylogeny of Calvin cycle enzymes. Also called phylogenesis.
2. A model or diagram delineating such an evolutionary history: a molecular phylogeny of the annelids.
3. A similar model or diagram delineating the development of a cultural feature.

Resolving the phylogeny of the Murinae will greatly benefit such diverse fields as Old World biogeography, biodiversity, mammalian paleontology, mammalian molecular-clock studies, and even virology, immunology, and related biomedical fields.
These genes have previously been found to resolve evolutionary relationships at the family, genus, and species levels; combining phylogenies from both of these molecular markers will produce a phylogeny with a higher degree of resolution.
