The single largest group of mammals is the Rodentia.
Their ancestry is probably to be found among a group of small fossil mammals known as anagalids, which may also have given rise to the Lagomorpha.
The living rodent with the most archaic characters, most like the common ancestor of the Rodentia, is the sewellel or mountain beaver (which is not a true beaver at all) of the northwestern United States.

With over 2000 living species placed in about 30 families, rodents are by far the largest order of mammals, at least in terms of number of taxa (well over 40% of mammalian species belong to the order Rodentia!).
Rodents range in size from pygmy mice weighing 5 gms to capybaras, the largest of which weigh over 70 kg.

 Order: Rodentia | Animals | Chaffee Zoological Gardens of Fresno   (Site not responding. Last check: )
The name itself is derived from the Latin verb rodere, meaning "to gnaw." It is the largest mammalian order, with over 1700 species, or about half of all mammalian species.
Given the number of species commonly grouped in the 35 families of Rodentia and the fact that even the experts do not agree on what is the best classification, the rodents are grouped into three suborders.
The potential for the order Rodentia to cause damage comes from their diversity and adaptability due to high reproductive rate, and their ability to live in close association with man. Some rodents pose a dangerous threat to humans as vectors of diseases such as typhus, bubonic plague, hunta virus and, occasionally, rabies.

Rodents are the most abundant land mammals, climbing or gliding among trees, darting across the ground, burrowing beneath the soil, or even swimming in lakes or streams.
These chisel-like incisors, kept sharp through wear since there is hard enamel only on their front surface, are ever growing and extremely effective for gnawing.
The beaver's industry in felling trees is the classic example, and is why the word "rodentia" is used, since it means "gnawing."

Phylogenetic analysis of DNA sequences from primates, rodents, lagomorphs, artiodactyls, carnivores, and birds strongly suggests that the order Rodentia is an outgroup to the other four mammalian orders and that Artiodactyla and Carnivora belong to a superordinal clade.
The branching date for Rodentia could be as early as 100 million years ago.

 Order Rodentia   (Site not responding. Last check: )
The name Rodentia is derived from the Latin verb rodere (to gnaw), in allusion to the gnawing habits of the group.
Among North American mammals, rodents are unique in that the incisors are reduced in number to one on each side above and below, in the absence of canines, and in the presence of never more than two premolars in each jaw above and one below.
Dorsal coloration with considerable yellow or buff; top of head same color as back; flanks of adults predominantly bright yellowish brown; first of two lower molars usually without any accessory lophids or stylids: Peromyscus boylii (brush mouse).

 Pet Rodent Classification
For the most reliable source of nomenclature and classification, consult the relevant scientific literature.
(1) The old classification within the order Rodentia used to include three suborders: (a) Sciuromorpha (squirrel-like rodents), (b) Myomorpha (rat-like rodents), and (c) Hystricomorpha (porcupine-like rodents).
The old suborders Sciuromorpha and Myomorpha basically combine to become infraorders of Sciurognathi, with two families of Sciuromorpha (Geomyidae and Heteromyidae) switching into Myomorpha.
