Rodents are believed to obtain evolved in Asia, the place local multituberculate faunas have been seriously impacted from the Cretaceous–Paleogene extinction party and in no way completely recovered, as opposed to their North American and European kin. During the ensuing ecological vacuum, rodents as well as other Glires have been capable of evolve and diversify, using the niches still left by extinct multituberculates.
