3-428: Glires ( / ˈ ɡ l aɪər iː z , - aɪər z / , 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. Two morphological studies, published in 2001 and 2003, strongly support the monophyly of Glires. In particular,
6-621: The 2003 study reported the discovery of fossil material of basal members of Glires, particularly the genera Mimotona , Gomphos , Heomys , Matutinia , Rhombomylus , and Sinomylus . Their description, in 2005, helped to bridge the gap between more typical rodents and lagomorphs. Data published in 2001, based on nuclear DNA, supported Glires as a sister of Euarchonta to form Euarchontoglires , but some genetic data from both nuclear and mitochondrial DNA have been less supportive. A study, published in 2007, investigating retrotransposon presence/absence data unambiguously supports
9-503: The Glires hypothesis. Studies published in 2011 and 2015 place Scandentia as a sister clade of the Glires, invalidating Euarchonta as a clade.
