Desk of Contents As documented by fossils, the evolutionary historical past of rodents extends back 56 million yrs into the Late Paleocene Epoch in North The united states. All those species, nevertheless, are regarded as to possess originated in Eurasia, Hence the origin in the get Rodentia is surely more mature. However, lack of fossil evidence previous to the Late Paleocene tends to make the understanding of evolutionary interactions among rodents over the familial degree a continuing quest.

The cladogram down below demonstrates the inner and outer relations of Rodentia based on a 2012 try by Wu et al. to align the molecular clock with paleontological facts:[112] Boreoeutheria
Common degus have a complex vocal repertoire.

Rodents absolutely are a prevalent group of mammals, they arise in many terrestrial habitats and they are only absent from Antarctica, New Zealand, and A few oceanic islands.
Rodents are customers on the purchase Rodentia, and that is the largest order of mammals. Rodents are mostly distinguished by their enamel—the term "rodent" comes from the Latin word rodere, which means "to gnaw."

Rodents are frequently probably the most plentiful smaller vertebrates of their habitats and are a vital source of foodstuff for a number of other animals, together with birds, reptiles, together with other mammals. If their figures were not kept in Examine by predators, rodents would quickly above operate their environments.
