Lagomorphs and rodents form the clade or grandorder Glires. Despite the evolutionary relationship between lagomorphs and rodents, the two orders have some major differences. Lagomorphs have four incisors in the upper jaw (smaller peg teeth behind larger incisors), whereas rodents only have two. They are similar to rodents in that their incisors ...
Glires (/ ˈ ɡ l aɪər iː z,-aɪər z / [citation needed], Latin glīrēs 'dormice') is a clade (sometimes ranked as a grandorder) consisting of rodents and lagomorphs (rabbits, hares, and pikas). The hypothesis that these form a monophyletic group has been long debated based on morphological evidence.
Simplicidentata is a group of mammals that includes the rodents (order Rodentia) and their closest extinct relatives. The term has historically been used as an alternative to Rodentia, contrasting the rodents (which have one pair of upper incisors) with their close relatives the lagomorphs (which have two). [1]
Although once considered rodents, lagomorphs diverged earlier and have a number of traits rodents lack, including two extra incisors. Similarities between rabbits and rodents were once attributed to convergent evolution, but studies in molecular biology have found a common ancestor between lagomorphs and rodents and place them in the clade Glires.
Euarchontoglires (from: Euarchonta ("true rulers") + Glires ("dormice")), synonymous with Supraprimates, is a clade and a superorder of placental mammals, the living members of which belong to one of the five following groups: rodents, lagomorphs, treeshrews, primates, and colugos.

Lagomorpha is an order of placental mammals, comprising the rabbits, hares, and pikas. Members of this order are called lagomorphs. It currently comprises 93 extant species, which are grouped into 12 genera. Lagomorphs live on every major landmass except Antarctica, and in a variety of habitats, especially forests, grasslands, shrublands, and ...
