Resolution of the Early Placental Mammal Radiation Using Bayesian Phylogenetics
Crown-group Eutheria may have their most recent common ancestry in the Southern Hemisphere (Gondwana), and placental phylogeny is investigated using Bayesian and maximum-likelihood methods and a 16.4-kilobase molecular data set.
Parallel adaptive radiations in two major clades of placental mammals
Two independent molecular data sets, having aligned lengths of DNA of 5,708 and 2,947 base pairs, respectively, are analysed for all orders of placental mammals to resolve placental orders into four groups: Xenarthra, Afrotheria, Laurasiatheria, and Euarchonta plus Glires.

The nonparametric bootstrap resampling procedure is applied to the Bayesian approach and shows that the relation between posterior probabilities and bootstrapped maximum likelihood percentages is highly variable but that very strong correlations always exist when Bayesian node support is estimated onbootstrapped character matrices.

Combined protein universal trees are highly congruent with SSU rRNA trees in their strong support for the separate monophyly of domains as well as the early evolution of thermophilic Bacteria.
Lateral gene transfer and the origins of prokaryotic groups.
Evidence for an important role of LGT in the evolution of photosynthesis, aerobic respiration, nitrogen fixation, sulfate reduction, methylotrophy, isoprenoid biosynthesis, quorum sensing, flotation (gas vesicles), thermophily, and halophily is reviewed.

A molecular phylogeny for members of the endemic African mammalian order Macroscelidea (elephant shrews) with molecular-clock calculations provides convincing evidence that the genus Elephantulus is diphyletic, and provides compelling evidence for a complex history of mosaic evolution.

It is argued that future analyses of evolution and biogeography in subsurface, or more generally in extreme environments, should consider dispersal ability as an evolving trait and morphology as a potentially biased marker.

It is suggested that intragenomic heterogeneity of rRNA operons is an ancient and stable trait in several lineages of the Halobacteriales.
