These disagreements continue to be unresolved, nor have molecular experiments totally fixed the problem however they may have verified the monophyly with the team and which the clade has descended from a typical Paleocene ancestor. Carleton and Musser (2005) in Mammal Species of the globe have provisionally adopted a 5 suborder procedure: Sciuromorpha, Castorimorpha, Myomorpha, Anomaluromorpha, and Hystricomorpha.

The impression of such species on human populations ranges from inconvenient to deadly. Crops are destroyed ahead of harvest; saved food stuff is contaminated by rodent squander; water-impounding constructions leak from burrowing; and objects are broken by gnawing.
