Resolution of the Early Placental Mammal Radiation Using Bayesian Phylogenetics
TLDR
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.

Molecular evidence for multiple origins of Insectivora and for a new order of endemic African insectivore mammals.
The traditional views regarding the mammalian order Insectivora are that the group descended from a single common ancestor and that it is comprised of the following families: Soricidae (shrews),…

Asynchronous colonization of Madagascar by the four endemic clades of primates, tenrecs, carnivores, and rodents as inferred from nuclear genes.
TLDR
A simultaneous reconstruction of phylogeny and age of the four radiations based on a 3.5-kb data set from three nuclear genes supports each as a monophyletic clade, sister to African taxa, and thereby identifies four events of colonization out of Africa.

Arrival and diversification of caviomorph rodents and platyrrhine primates in South America.
TLDR
Considering both the fossil record and these molecular datings, the favored scenarios are a trans-Atlantic migration of primates from Africa at the end of the Eocene or beginning of the Oligocene, and a colonization of South America by rodents during the Middle or Late Eocene.

Rodent phylogeny and a timescale for the evolution of Glires: evidence from an extensive taxon sampling using three nuclear genes.
TLDR
Molecular datings based on three nuclear genes suggest that the rodent radiation took place at the transition between Paleocene and Eocene, and the association of Rodentia with Lagomorpha (the Glires clade), and a Glires + Euarchonta (Primates, Dermoptera, and Scandentia) clade is supported.

Microbat paraphyly and the convergent evolution of a key innovation in Old World rhinolophoid microbats
Molecular phylogenies challenge the view that bats belong to the superordinal group Archonta, which also includes primates, tree shrews, and flying lemurs. Some molecular studies also challenge…

Molecular phylogeny of living xenarthrans and the impact of character and taxon sampling on the placental tree rooting.
TLDR
Maximum likelihood and Bayesian phylogenetic analyses of a 47 placental taxa data set resolved the phylogeny of Xenarthra with some evidence for two radiation events in armadillos and provided a strongly supported picture of placental interordinal relationships.

Integrated fossil and molecular data reconstruct bat echolocation
TLDR
A methodological approach is employed that allows for the integration of molecular and paleontological data in deciphering one of the most innovative features in the evolutionary history of mammals—laryngeal echolocation in bats.
