Inferred relationships within the superorder Euarchontoglires. Solid lines indicate branching suggested by a supertree integrating molecular data [20]. Dashed lines with question marks indicate possible alternative links. A basal split between Euarchonta and Glires is often recognized, but some molecular evidence indicates a link between tree-shrews (Scandentia) and lagomorphs. Within Euarchonta, colugos (Dermoptera) have been linked either with tree-shrews [8] or with primates [9]. Molecular evidence has generally provided little support for a specific link between tree-shrews and primates.
