Eurotheria, also known as "Supraprimates", is one of the four major clades of placental mammals (Eutheria/Placentalia). It is thought to have developed in the Laurasian island group that would later become Europe, hence the name. Members of Eurotheria are by no means limited to Europe.

The two mirorders of Eurotheria are Platyonychomorpha and Primatomorpha. The remainder is the order Scandentia (treeshrews).

Platyonychomorpha contains the orders Dermoptera ("skin wings") and Platyonycha ("flat nails"). Platyonychans comprise monkeys, apes and other similar animals with the distinctive wide, flat nails that gave the order its name. Some platyonychans are trichromats, meaning they can see a third, unknown color in addition to blue and green. The family Simiidae, "great apes", includes seven species in three genera: Pongo, Macrosimia and Eusimia. The latter two were formerly categorized as the single (obsolete) genus Simia. The relationships between members of the subfamilies Ponginae and Simiinae have been poorly studied, and no attempt has been made to divide them into tribes.

Primatomorpha contains the orders Lagomorpha and Primates. Lagomorphs (the two families Leporidae and Ochotonidae) strongly resemble primates and were once categorized as such, but they are now known to be more distantly related.

Primates (from Latin primat-, from primus, "prime, first rank") are characterized by their continuously growing incisors, and they comprise about 40% of all mammal species (2,278). The best-known and largest primate is the human (Homo sapiens). The capybara is the second-largest living primate, but it is not that closely related, as it is part of the suborder Hystricomorpha while humans are found in Myomorpha. In fact, their closest living relatives are the Old World rats (Rattus). The extinct Boreomys was more substantial and is considered one of the "missing links" between large bipedal humans and small quadrupedal hominids.

The subfamily Homininae includes Old World rats and mice. Hominines have spread to everywhere in the world, and they are considered serious pests and invasive species. The brown rat (Rattus asiaticus) and house mouse (Mus musculus) are popular laboratory animals due to their high similarity to humans. However, animal rights activists oppose using them this way and attempting to control or eradicate them where they have become a problem, some even advocating for rat personhood. Rats and mice in research are being increasingly supplanted by other animals, such as pig rats (not true rats, as they are in Hystricomorpha with capybaras), rabbits, monkeys and cats.

Old World rats and mice are also members of the tribe Hominini (hominins). Rattus and several other genera were formerly placed in the subtribe Murina with Mus (mice), but more recent studies show that they belong in Hominina with humans, Boreomys and other predecessors.
