Euarchontoglires (from: Euarchonta ("true rulers") + Glires ("dormice")), synonymous with Supraprimates, is a clade and a superorder of mammals, the living members of which belong to one of the five following groups: rodents, lagomorphs, treeshrews, primates, and colugos.
Evolutionary affinities within mammals
Phylogenetic position of Euarchontoglires (in blue) among placentals in a genus-level molecular phylogeny of 116 extant mammals inferred from the gene tree information of 14,509 coding DNA sequences.[3] The other major clades are colored: marsupials (magenta), xenarthrans (orange), afrotherians (red), and laurasiatherians (green).

The Euarchontoglires clade is based on DNA sequence analyses and retrotransposon markers that combine the clades Glires (Rodentia + Lagomorpha) and Euarchonta (Scandentia + Primates + Dermoptera).[1] It is usually discussed without a taxonomic rank but has been called a cohort, magnorder, or superorder. Relations among the four cohorts (Euarchontoglires, Xenarthra, Laurasiatheria, Afrotheria) and the identity of the placental root remain controversial.[4][5]

So far, few, if any, distinctive anatomical features have been recognized that support Euarchontoglires; nor does any strong evidence from anatomy support alternative hypotheses.[citation needed] Although both Euarchontoglires and diprotodont marsupials are documented to possess a vermiform appendix, this feature evolved as a result of convergent evolution.[6]

Euarchontoglires probably split from the Boreoeutheria magnorder about 85 to 95 million years ago, during the Cretaceous, and developed in the Laurasian island group that would later become Europe.[citation needed] This hypothesis is supported by molecular evidence; so far, the earliest known fossils date to the early Paleocene.[7] The combined clade of Euarchontoglires and Laurasiatheria is recognized as Boreoeutheria. Phylogenetic relationships within the clade

^]

One study based on DNA analysis suggests that Scandentia and Primates are sister clades, but does not discuss the position of Dermoptera.[9] Although it is known that Scandentia is one of the most basal Euarchontoglires clades, the exact phylogenetic position is not yet considered resolved, and it may be a sister of Glires, Primatomorpha or Dermoptera or to all other Euarchontoglires.[10][5][11] Some old studies place Scandentia as sister of the Glires, invalidating Euarchonta.[12][13]

Whole-genome duplication may have taken place in the ancestral Euarchontoglires.[14]
