Forty percent of mammal species are rodents, and they are found in vast numbers on all continents other than Antarctica. Common rodents include mice, rats, squirrels, gerbils, porcupines, beavers, chipmunks, guinea pigs, and voles. Rodents have sharp incisors that they use to gnaw wood, break into food, and bite predators. Most eat seeds or plants, though some have more varied diets. Some species have historically been pests, eating seeds stored by people and spreading disease.
The name comes from the Latin word ''rodens'', "gnawing one" (from the verb ''rodere'', "gnaw").
Rodents are found in vast numbers on all continents except Antarctica, most islands, and in all habitats except oceans. They are the only non-volant, non-marine placental order—and in particular are the only placental order besides bats (Chiroptera) and Pinnipeds—to have reached Australia without human introduction.
Rodents have two incisors in the upper as well as in the lower jaw which grow continuously and must be kept worn down by gnawing; this is the origin of the name, from the Latin ''rodere'', to gnaw. These teeth are used for cutting wood, biting through the skin of fruit, or for defense. The teeth have enamel on the outside and exposed dentine on the inside, so they self-sharpen during gnawing. Rodents lack canines, and have a space (diastema) between their incisors and premolars. Nearly all rodents feed on plants, seeds in particular, but there are a few exceptions which eat insects or fish. Some squirrels are known to eat passerine birds like cardinals and blue jays. Rodents are important in many ecosystems because they reproduce rapidly, and can function as food sources for predators, mechanisms for seed dispersal, and as disease vectors. Humans use rodents as a source of fur, as pets, as model organisms in animal testing, for food, and even for detecting landmines.
Members of non-rodent orders such as Chiroptera (bats), Scandentia (treeshrews), Soricomorpha (shrews and moles), Lagomorpha (hares, rabbits and pikas) and mustelid carnivores such as weasels and mink are sometimes confused with rodents.

Classification scheme:
ORDER RODENTIA (from Latin, ''rodere,'' to gnaw)
Several molecular phylogenetic studies have used gene sequences to determine the relationships among rodents, but these studies are yet to produce a single consistent and well-supported taxonomy. Some clades have been consistently produced such as:
The positions of the Castoridae, Geomyoidea, Anomaluridae, and Pedetidae are still being debated.
