16,25) Furthermore, PEG11/ RTL1 was acquired after the eutherian
/marsurpial split and before the split of the three major eutherian
lineages, boreoeutheria (including euarchontoglires and laurasiatheria), afrotheria and xenarthra 120 Ma (see Fig.
1990) encountered similarities in the distribution and relative frequency of endocrine cells in the duodenum of eight marsupial species as well when compared to eutherian
mammals, showing no difference between marsupials, herbivores, omnivores or carnivores.
Lack of supernumeration would be expected in eutherian
taxa with a full complement of 44 teeth, as seen in several species of moles.
Nucleotide and protein sequences of [beta]-globin gene in nine eutherian
(taxonomic classification given in Table 1a), Homo sapiens (GenBank Accession No.
mammals have an XY system where SRY on the Y determines maleness, so XXY is male and XO is female.
mammals like mice and humans protect their progeny for lengthy periods in an inner womb prior to giving birth.
Morton SR, Recher HF, Thompson SD, Braithwaite RW (1982) Comments on the Relative Advantages of Marsupial and Eutherian
Most of the information presented in this book pertains to the eutherian
Mammalian mitogenomic relationships and the root of the eutherian
Adaptive evolution of the uncoupling protein 1 gene contributed to the acquisition of novel nonshivering thermogenesis in ancestral eutherian
The BMR of eutherian
mammals is accurately predicted by the Klieber equation, based on body mass, (26) and humans fit this predictive value well, indicating no increase in basal metabolism.
Hyperthermia is also recognized as being teratogenic in eutherian
mammals, (21) the result of thermally induced apoptosis of cells during organogenesis.
