Euarchontoglires (synonymous with Supraprimates) is a clade of mammals, the living members of which include rodents and primates (including humans).

Evolutionary relationships

The Euarchontoglires clade is based on DNA sequence analyses and retrotransposon presence/absence data, combining the Glires clade, which consists of Rodentia and Lagomorpha, with that of Euarchonta, a clade consisting of Scandentia, Primates (which includes humans) and Dermoptera.

Euarchontoglires is now recognized as one of four major groups within Eutheria (containing placental mammals).[1] These four clades are ususally discussed without a Linnaean rank, but has been assigned the rank of cohort or magnorder, and superorder. Relations within the four cohorts, Euarchontoglires, Xenarthra, Laurasiatheria, and Afrotheria, and the identity of the placental root, remain somewhat controversial.[2]

Euarchontoglires probably split from the Laurasiatheria sister group about 85 to 95 million years ago during the Cretaceous, developing in the Laurasian island group which would later become Europe. This hypothesis is supported by fossil as well as molecular evidence. The clade of Euarchontoglires and Laurasiatheria is recognized as Boreoeutheria.

Organization

The hypothesized relationship among the Euarchontoglires is as follows:

Euarchontoglires
Glires

Anagaloidea?




Rodentia (rodents)



Lagomorpha (rabbits, hares, pikas)




Euarchonta

Scandentia (treeshrews)




Dermoptera (colugos)




Primates



Plesiadapiformes
