Placental Evolution in Therian Mammals
One of the great transformations in the history of vertebrates involves the origin and early diversification of the mammals. Mammals are distinguished from other vertebrates by almost countless aspects of their anatomy, physiology, behavior, reproduction, and life history. Many of these features appear to have arisen as an integrated complex during the early evolution of mammals. An exceedingly...
متن کاملThe evolution of placental mammals.
Based on morphological, virological, biochemical and molecular biological data, it is proposed that the presence of endogenous retrovirus particles in the placental cytotrophoblasts of many mammals is indicative of some beneficial action provided by the virus in relation to cell fusion, syncytiotrophoblast formation and the creation of the placenta. Further, it is hypothesised that the germ lin...
متن کاملSex Reversal in Non-Human Placental Mammals.
Gonads are very peculiar organs given their bipotential competence. Indeed, early differentiating genital ridges evolve into either of 2 very distinct organs: the testis or the ovary. Accumulating evidence now demonstrates that both genetic pathways must repress the other in order for the organs to differentiate properly, meaning that if this repression is disrupted or attenuated, the other pat...
متن کاملMicroparasites 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 کاملResolving the Family Tree of Placental Mammals
Background: Genetic analysis of Escherichia coli O157:H7 strains has shown divergence into two distinct lineages, lineages I and II, that appear to have distinct ecological characteristics, with lineage I strains more commonly associated with human disease. In this study, microarray-based comparative genomic hybridization (CGH) was used to identify genomic differences among 31 E. coli O157:H7 s...
