Orders
Laurasiatheria is a clade of rank cohort or super-order, within the Placentalia (living) or Eutheria (Placentals and their extinct ancestors) infraclass of mammals, based on DNA sequence analyses and Retrotransposon presence/absence data. The name comes from the theory that these mammals evolved on the supercontinent of Laurasia, after it split from Gondwana when Pangaea broke up. It is a sister group to Euarchontoglires (Supraprimates) and Afrotheria. It includes the following extant orders: Within the Laurasiatheria, the Erinaceomorpha appears (surprisingly) to be the most divergent branch. Some studies link the Perissodactyla and Ferae in a clade Zooamata; others link Perissodactyla and Cetartiodactyla in a clade of true ungulates. Neither clade is well supported.

Laurasiatheria is also posited to include several extinct orders:

Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. Scientific classification also can be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks scientific basis.
