Orders
Rodentia Lagomorpha

Glires is a proposed clade consisting of rodents and lagomorphs (rabbits, hares, and pikas). This hypothesis that these form a monophyletic group has been long debated based on morphological evidence. Recent data (2001) based on nuclear DNA support Glires as a sister of Euarchonta to form Euarchontoglires, but some genetic data from both nuclear and mitochondrial DNA have been less supportive. Wikipedia does not have an article with this exact name. ... Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...
