Phylogeny of the Squirrels (Rodentia, Sciuridae)

A number of phylogenetic studies have been performed on the family Sciuridae. This work seeks to validate and extend existing phylogenetic studies of Sciuridae with an analysis of the divergence times of a selected set of species. A total of five genes; 2 mitochrontrial ribosomal RNA genes (12S, 16S), a mitochrontrial protein coding gene (cytb) and two nuclear genes (IRBP, RAG1) were studied ac...
