The Euarchonta are a proposed grandorder of mammals: the order Scandentia (treeshrews), and its sister Primatomorpha mirorder, containing the Dermoptera (colugos) and the primates (Plesiadapiformes and descendants).
The term "Euarchonta"[2] (meaning "true rulers") appeared in 1999, when molecular evidence suggested that the morphology-based Archonta should be trimmed down to exclude Chiroptera.[3] Further DNA sequence analyses[4][5][6] supported the Euarchonta hypothesis. Despite multiple papers pointing out that some mitochondrial sequences showed unusual properties (particularly murid rodents and hedgehogs) and were likely distorting the overall tree,[7][8] and despite earlier studies[6] showing near total congruence of mtDNA-based and nuclear-based trees when such sequences were excluded, some authors continued to produce misleading trees.[9] A study investigating retrotransposon presence/absence data has claimed strong support for Euarchonta.[10] Some interpretations of the molecular data link Primates and Dermoptera in a clade (mirorder) known as Primatomorpha, which is the sister of Scandentia. In some, the Dermoptera are a member of the primates rather than a sister group. Other interpretations link the Dermoptera and Scandentia together in a group called Sundatheria as the sister group of the primates.
Euarchontoglires
Euarchonta and Glires together form the Euarchontoglires, one of the four eutherian clades.
