Glires (Latin glīrēs, dormice) is a clade (sometimes ranked as a grandorder) consisting of rodents and lagomorphs (rabbits, hares, and pikas). The hypothesis that these form a monophyletic group has been long debated based on morphological evidence, although recent morphological studies strongly support the monophyly of Glires.[1][2] In particular, the discovery of new fossil material of basal members of Glires, particularly the genera Mimotona, Gomphos, Heomys, Matutinia, Rhombomylus, and Sinomylus, has helped to bridge the gap between more typical rodents and lagomorphs.[2][3] Data based on nuclear DNA support Glires as a sister of Euarchonta to form Euarchontoglires,[4][5] but some genetic data from both nuclear and mitochondrial DNA have been less supportive.[6] A study investigating retrotransposon presence/absence data unambiguously supports the Glires hypothesis.[7] Recent studies place Scandentia as sister of the Glires, invalidating Euarchonta.[8][9]
