Did advanced mammals evolve on the southern continents and then move north? Not according to a new study, which concludes that such mammals evolved in both the south and the north.

Spiny Norman in the Garden of Eden? Dispersal and early biogeography of Placentalia
TLDR
The persistent finding of clades endemic to the southern continents (Afrotheria and Xenarthra) near the base of the placental mammal tree has led molecular phylogeneticists to suggest an origin of Placentalia, the crown group of Eutheria, somewhere in the southern continent with few supraordinal splits occurring before the last 5–10 million years of the Cretaceous.

Third meeting of the International Society for Phylogenetic Nomenclature: a report
TLDR
Topics discussed at the ISPN meeting include problems created by rank-based nomenclature in various eukaryotic taxa, dealing with hybrids in rank‐based and phylogenetic nomenClature, phyloinformatics, the choice of names to use when the taxonomic content associated with available names varies, teaching phylogeneticnomenclumber, and the application of phylogeneticNomenclatures to specific taxa.

Programmed Frameshifting in Budding Yeast
TLDR
The budding yeast, Saccharomyces cerevisiae, and the endogenous L-A virus provided two of the earliest analyzed examples of programmed translational frameshifted events, andBioinformatic analysis suggests that many genes may employ −1 frameshifting although the function of the frameshift in those genes remains controversial.

Molecular systematics: The platypus put in its place
TLDR
The duck-billed platypus is a monotreme - a mammal that lays eggs that has been seen as more primitive than both marsupial and placental mammals, and placed on an evolutionary lineage which pre-dates the divergence of marsupials and placentals. Expand

Dual origin of tribosphenic mammals
TLDR
Phylogenetic and morphometric analyses including these newly discovered taxa suggest a different interpretation: that mammals with tribosphenic molars are not monophyletic. Expand

M6P/IGF2R imprinting evolution in mammals.
TLDR
It is shown that M6P/IGF2R is not imprinted in monotremes and does not encode for a receptor that binds IGF2, and invasive placentation and gestational fetal growth are not required for imprinted genes to evolve. Expand
