1. Eutherians, like their closest relatives the marsupials, give birth to live young
2. In Eutherians, however, the young are nurtured within the body of the mother by the placenta, which allows nutrients to pass from the blood of the mother almost directly into the blood of the young.
3. Placentals (extant Eutherians) and studies using fossil taxa, 18 orders of placental are usually recognized (Figure 1)
4. "Eutherians are the group that led ultimately, evolutionarily, to the placental mammals, of which we're one, as well as blue whales and pygmy shrews," said study lead author Steven Sweetman, a

12. The corticospinal tract is unique to mammals and the corpus callosum is unique to placental mammals (Eutherians)
13. Eutherians are often mistakenly termed 'placental mammals', but marsupials also have a placenta to mediate early embryonic development

14. Lactation is necessary for both infant and fetal development in Eutherians and marsupials, although marsupials have a far more complex milk repertoire that facilitates morphogenesis of developmentally immature young.
15. The marsupial branch of mammals in the Metatheria, have been separated from the Eutherians for about 148 Mya.There are more than 250 living species distributed throughout the Americas and Australasia and characterised by birth, after a short period of gestation, of very early stage neonates that have long periods of development attached to a teat in a pouch or in the mammary area of some
16. - In many Eutherians, this is known to be accomplished by production of chorionic gonadotropins, which (among other things) maintain the trophoblast and suppress maternal immune reaction
17. Mammalia is a class of vertebrates that can be categorized into three groups: monotremes, marsupials, and Eutherians (placental mammals)
18. Eutherians: An ancient grouping of animals, Eutherians are characterized by an enlarged malleolus the bottom of the tibia and the joint between the first metatarsal bone and the entocuneiform bone
Eutherians, Enlarged, Entocuneiform
19. Eutherians "solved" the problem of immune rejection through the evolution of a complex set of interactions that take place in the trophoblast, a part of the developing egg of Eutherians that is not found in marsupials

21. In Eutherians and in marsupials, the desiquilibrium in gene dosage between XY males and XX females is compensated for by silencing one of the X chromosomes in females (2–4)
22. In Eutherians, this silencing involves the Xist gene, which is located in the X inactivation center (Xic) and encodes a long untranslated RNA .
23. Thus the Mongolian Cretaceous Eutherians, unlike placentals (living Eutherians), might have had a short gestation period that necessitated prolonged suspension of the …

Eutherian definition is - of or relating to a major division (Eutheria) of mammals comprising the placental mammals. ... Recent Examples on the Web To do that, Harris Lewin, an evolutionary geneticist at the University of California ...
(Zoology) of, relating to, or belonging to the Eutheria, a subclass of mammals all of which have a placenta and reach an advanced state of development before birth. The group includes all mammals except monotremes and marsupials 1. belonging or pertaining to the group Eutheria, comprising the placental mammals. n. 2. a eutherian animal.
Except for the North American Virginia opossum, which is a metatherian, all post- Miocene mammals indigenous to Europe, Africa, Asia, and North America north of Mexico are eutherians. Extant eutherians, their last common ancestor, and all extinct descendants of that ancestor are members of Placentalia .
Eutherians are distinguished from noneutherians by various phenotypic traits of the feet, ankles, jaws and teeth. All extant eutherians lack epipubic bones, which are present in all other living mammals (marsupials and monotremes). This allows for expansion of the abdomen during pregnancy.
