The cladogram beneath displays the internal and outer relations of Rodentia according to a 2012 attempt by Wu et al. to align the molecular clock with paleontological details:[112] Boreoeutheria
Popular degus have a posh vocal repertoire.

The incisor teeth of rodents are their most unique attribute. A rodent's incisors mature continuously during its lifetime and must be saved worn down by gnawing. The incisors of a pocket gopher can develop twenty inches in a single 12 months.
Extirpation of prairie dogs can also lead to regional and native biodiversity decline, greater seed depredation, plus the institution and spread of invasive shrubs.[23] Burrowing rodents may perhaps eat the fruiting bodies of fungi and spread spores as a result of their feces, thereby letting the fungi to disperse and form symbiotic relationships with the roots of crops (which typically cannot prosper with out them). As such, these rodents could Engage in a role in keeping nutritious forests.[25]
