Rodents are thought to get progressed in Asia, where by nearby multituberculate faunas were severely influenced by the Cretaceous–Paleogene extinction occasion and hardly ever thoroughly recovered, not like their North American and European family members. During the ensuing ecological vacuum, rodents together with other Glires were in the position to evolve and diversify, having the niches still left by extinct multituberculates.
