Rodents have high rate of reproduction.
Breeding occurs mostly in spring and fall. Because of their high reproductive rates and ability toinvade many habitats, rodents are able to spread and multiply quickly.

These animals, however, diversified into leaping, running andburrowing forms between 54 and 38 million years ago.
