The literature on postcranials, whether descriptive or analytical, paleontological or neontological, is amazingly scanty for the largest of the mammalian orders, the Rodentia. Although some excellent descriptions can be found on fossils (see especially Wood, 1937, 1962; Emry and Thorington, 1982), and equally important contributions have been made to comparative myology of the postcranium (e. g., Hildebrand, 1978; Woods, this volume, and references therein), this evidence has not been utilized convincingly to attempt an understanding of the origins and relationships, and the early postcranial adaptations of the order. My aim in this paper is to concentrate on these two closely interrelated goals of evolutionary analysis, primarily for the Rodentia, but with some definite observations on the Lagomorpha, sensu lato, as well.
