A taxonomic group within Class Mammalia (as first proposed by Thomas Henry Huxley in 1880) comprised of eutherian mammals in which viviparous, chorioallantoic placentals give birth to well developed young


Most mammals belong to this group, including primates and humans. They differ from non-eutherian mammals from having a chorioallantoic placenta that allows the embryo to grow into a well developed foetus.

Word origin: Greek eu (true) + thērion (beast)
