Euarchontoglires
Euarchontoglires
(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, colugos and primates.

Evolutionary relationships[edit] The Euarchontoglires
Euarchontoglires
clade is based on DNA
DNA
sequence analyses and retrotransposon markers that combine the clades Glires
Glires
(Rodentia + Lagomorpha) and Euarchonta
Euarchonta
( Scandentia
Scandentia
+ Primates
Primates
+ Dermoptera).[citation needed] So far, few if any anatomical features that support Euarchontoglires
Euarchontoglires
have been recognized, nor does any strong evidence from anatomy support alternative hypotheses. Euarchontoglires
Euarchontoglires
is now recognized as one of the four major subclades within the clade Eutheria
Eutheria
(i.e., placentalia (placental mammals)[1]), and it is usually discussed without a taxonomic rank but has been regarded as a cohort, magnorder, or superorder. Relations among the four cohorts (Euarchontoglires, Xenarthra, Laurasiatheria, Afrotheria) and the identity of the placental root, remain controversial.[2] Euarchontoglires
Euarchontoglires
probably split from the Laurasiatheria
Laurasiatheria
sister group about 85 to 95 million years ago, during the Cretaceous, and developed in the Laurasian island group that would later become Europe. This hypothesis is supported by molecular evidence; so far, the earliest known fossils date to the early Paleocene.[3] The clade of Euarchontoglires
Euarchontoglires
and Laurasiatheria
Laurasiatheria
is recognized as Boreoeutheria.[citation needed] Both Euarchontoglires
Euarchontoglires
and diprotodont marsupials are documented to possess a vermiform appendix, although this evolved as a result of convergent evolution.[4] Organization[edit] The hypothesized relationship among the Euarchontoglires
Euarchontoglires
is as follows:

Boreoeutheria

Euarchontoglires

Scandentia
Scandentia
(treeshrews)

Gliriformes

†Anagaloidea?

†Arctostylopida[5]

Glires

Rodentia (rodents)

Lagomorpha
Lagomorpha
(rabbits, hares, pikas)

Primatomorpha

Dermoptera
Dermoptera
(colugos)

Primates

†Plesiadapiformes

Laurasiatheria

One study based on DNA
DNA
analysis suggests that Scandentia
Scandentia
and Primates are sister clades, but did not discuss the position of Dermoptera.[6] Although it is known that Scandentia
Scandentia
is one of the most basal Euarchontoglire clades, the exact phylogenetic position is not yet considered resolved, and it may be a sister of Glires, Primatomorpha or Dermoptera
Dermoptera
or to all other Euarchontoglires.[7][8][9] Recent studies place Scandentia
Scandentia
as sister of the Glires, invalidating Euarchonta.[10][11] References[edit]
