Charlie Cochet's Darkest Hour Before Dawn is the ninth installment in the THIRDS series, a paranormal gay romance saga about a militarized law enforcement team of Therians
, humans that shape-shift into animals.
Another imprinted region that has a common DMR in the therians
is the IGF2-H19 region.
Homology of platypus X1 and X5 with the therian
(eutherians and marsupials) XY PAR and bird ZW-system, respectively, is consistent with this species' position in the phylogenetic tree between birds, reptiles, and therians
Dryolestoids are most closely related to a modern group of mammals called therians
, which includes marsupials such as opossums and placental mammals such as people.
Typical n ode-based definitions, then, might read as follows: "Lepidosauria is the most recent common ancestor of Sphenodon and squamates and all of its descendants" or "Mammalia is the most recent common ancestor of montremes and therians
and all of their descendants."
If these hypotheses are general for therians
, it follows that in metatherians the extremely short gestation period, the need to achieve minimal functionality of somatic systems, the necessity for sufficient allocation to these systems for morphogenesis, and the rate-limiting nature of neurogenesis are incompatible.
Paleontologists divide today's mammals into two major groupings: monotremes and therians
. Monotremes, the primitive, egg-laying mammals, include only the duck-billed platypus, a creature called the echidna, and a few extinct forms.
Meng and Fox (1995, p.61) also stated based on literature review (e.g., Gray, 1907) that "in living therians
, only the marsupial mole, the hedgehog, and the sea-cow posses a cochlea with as few as one and a half turns." To this list we would add Vombatus ursinus, which also exhibits less than 1.5 complete turns of the cochlea.
The faunule is composed exclusively of therian
forms, and more specifically of zhelestid eutherians.
Petrosals of Late Cretaceous Marsupials from North America, and a Cladistic Analysis of the Petrosal in Therian
The two most obvious features present in therian
mammals but not shared by birds are a claustrum and the neocortical cytoarchitecture, including neurons with polarized dendrites, cortical columns, a great variety of cell types, and a highly stratified organization of afferent innervation.
