Neural development in metatherian and eutherian mammals: variation and constraint.
A model for predicting the timing of neurogenesis in mammals (Finlay and Darlington [1995] Science 268:1578-1584) is here extended to an additional five metatherian species and to a variety of other events in neural development. The timing of both the outgrowth of axonal processes and the establishment and segregation of connections proves to be as highly predictable as neurogenesis. Expressed ...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولMicroparasites and Placental Invasiveness in Eutherian Mammals
Placental invasiveness-the number of maternal tissue layers separating fetal tissues from maternal blood-is variable across mammalian species. Although this diversity is likely to be functionally important, variation in placental invasiveness remains unexplained. Here we test the hypothesis that increased risk of transplacental transmission of pathogens from the mother to the fetus promotes the...
متن کاملEvolution of the placenta in eutherian mammals.
We review recent advances in our understanding of placental evolution with particular focus on the interhaemal barrier. It seems likely that the non-invasive, epitheliochorial placentation of living eutherians is a derived state. However, there is disagreement on whether the last common ancestor of eutherian mammals had an endotheliochorial placenta or a haemochorial one. Research has been stim...
متن کاملDivergence Times of Eutherian Mammals
In the continuing debate about the timing of the origin of major extant placental clades, both proponents of a divergence after the Cretaceous-Tertiary (K-T) boundary and those advocating divergence deep within the Cretaceous too often miss what the Late Cretaceous record of placentals actually shows. For example, Foote et al. (1) are correct that many Late Cretaceous reports of extant ordinal ...
