Highly derived eutherian mammals from the earliest Cretaceous of southern Britain.

Double cones were present, a feature not found in eutherian mammals or marsupials.

These properties are again analogous to those observed for eutherian IGFBPs.

A Jurassic eutherian mammal and the divergence of marsupials and placentals.

The origins of eutherian mammals is one such problematic case.

The exact origins of eutherian mammals is among them.

As a consequence of random decay and chromosome rearrangements over evolutionary time, Y chromosome gene repertoires differ between eutherian lineages.

Galectins are glycan-binding proteins that regulate innate and adaptive immune responses, and some confer maternal-fetal immune tolerance in eutherian mammals.

The sperm DNA of the marsupial species studied were significantly more sensitive to oxidative stress than the spermatozoa of eutherian species.

N- and C-terminal regions of possum alpha-lactalbumin were also sequenced and have been compared with wallaby alpha-lactalbumin and several eutherian alpha-lactalbumins.

We discuss the possibility that these additional somatosensory areas (SC and SR) are homologous to somatosensory areas in eutherian mammals.

Our results indicate the domestic cat Y chromosome has retained most X-degenerate genes that were present on the ancestral eutherian Y chromosome.

Upon the emergence of eutherian mammals, one of them was lost, whereas, the other acquired a novel genomic environment owing to translocation.

X-chromosome inactivation (XCI) is the epigenetic transcriptional silencing of an X-chromosome during the early stages of embryonic development in female eutherian mammals.

Comparative mapping of the X chromosome in eutherian mammals has revealed distinct regions of conservation as well as evolutionary rearrangements between human and mouse.

Unlike other eutherians, but similar to other marsupials investigated, only 40% of the neurons were orientation selective.
