	Placentalia - Wikipedia, the free encyclopedia
		Placentalia and Eutheria are terms used to describe major groupings within the animal class of Mammalia.
		The Placentalia are distinguished from other mammals in that the fetus is nourished during gestation via a placenta while, in general, this is not the case with other mammals (Bandicoots are a conspicuous exception to this rule).
		It is undoubtably a member of Placentalia, but the hips of the animal are too narrowly built to have allowed the birth of well-developed young.

		This is a classification system nearly synonymous with Placentalia.
		Introduced by Thomas Henry Huxley in 1880, he meant for it to be more broad in definition than its precursor Placentalia.
		However, the noun placental is used almost universally to describe a placental mammal; placental mammals are rarely, if ever, referred to as eutheres.

		Placentalia is the name of one of the principal groups of living mammals, and is often used in scientific classification as a subclass or an infraclass.
		The Placentalia are uniquely different from all other mammals in that the fetus is nourished during gestation via the placenta.
		The lineage is first known from the Lower Cretaceous of China, (Eomaia).

		Cimolesta and Placentalia share the familiar way of reproduction – they retain their young in the womb at least until they are fully enough developped to breathe with their lungs (instead of the skin).
		Now that we know that cimolestans share its famous mode of reproduction, Placentalia appears as a misnomer, but due to the way how scientific names are defined, we are stuck with it.
		It is the sistergroup of the rest of Placentalia.

		The mammals are the class of vertebrate animals primarily characterized by the presence of mammary glands in the female which produce milk for the nourishment of young; the presence of hair or fur; and which have endothermic or "warm blooded" bodies.
		They remained small and shrew-like throughout the era, but radiated rapidly after the Cretaceous-Tertiary extinction event 65 million years ago.
		The names "Prototheria", "Metatheria" and "Eutheria" expressed the theory that Placentalia were descendants of Marsupialia, which were in turn descendants of Monotremata, but this theory has been refuted.

		First, the eptenyctans evolved flight while mammals were still mostly egg-layers (originally all mammals were egg-layers; only later did various groups evolve such arcane alternatives we see in the major modern mammal groups: the Marsupialia and Placentalia).
		Nyctotherians, in contrast to the other living Subclasses (Marsupialia and Placentalia), retain the trait of laying eggs which is primitive to mammals.
		Nyctotherians diverged from the other lineages before this trait was replaced by more derived reproductive strategies among the Marsupialia and Placentalia.
