Chromosomal Evolution in Rodents

  • Charles F. Nadler


The order Rodentia, composed of 1687 recent species belonging to 43 families and 354 genera, occupies a wide range of habitats throughout the world (Anderson and Jones, 1967). Rodents have been classified within three suborders: the Sciuromorpha, Myomorpha, and the Hys-tricomorpha, although the validity of suborders has been questioned (Wood, 1958). The various gross morphological features characterizing these groups, as well as the families and genera of rodents, are presented in several recent publications (Walker, 1964; Anderson and Jones, 1967). An invaluable taxonomic reference that described species and subspecies of North American rodents is the publication by Hall and Kelson (1959).
