Glires Rodentia Lagomorpha Euarchonta Dermoptera Scandentia Primates

The Euarchontoglires are a mammalian superorder based on molecular genetic research, combining the Glires clade, which consists of the Rodentia and the Lagomorpha, with that of the Euarchonta, a clade consisting of the Scandentia, the Primates and the Dermoptera.
