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.
Impacts of the Cretaceous Terrestrial Revolution and KPg Extinction on Mammal Diversification
Molecular phylogenetic analysis, calibrated with fossils, resolves the time frame of the mammalian radiation and diversification analyses suggest important roles for the Cretaceous Terrestrial Revolution and KPg mass extinction in opening up ecospace that promoted interordinal and intraordinal diversification, respectively.

The results support the hypothesis that megabats are nested among four major microbat lineages, which originated in the early Eocene, coincident with a significant global rise in temperature, increase in plant diversity and abundance, and the zenith of Tertiary insect diversity.

The largest available molecular data set for placental mammals is investigated, which includes segments of 19 nuclear and three mitochondrial genes for representatives of all extant placental orders and permits simultaneous constraints from the fossil record and allows rates of molecular evolution to vary on different branches of a phylogenetic tree.
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.
Comparative genomics reveals insights into avian genome evolution and adaptation
This work explored bird macroevolution using full genomes from 48 avian species representing all major extant clades to reveal that pan-avian genomic diversity covaries with adaptations to different lifestyles and convergent evolution of traits.
Macroevolutionary Dynamics and Historical Biogeography of Primate Diversification Inferred from a Species Supermatrix
A robust molecular phylogeny for 70 primate genera and 367 primate species is generated based on a concatenation of 69 nuclear gene segments and ten mitochondrial gene sequences, most of which were extracted from GenBank to find support for the hypothesis that the most recent common ancestor of living Primates resided in Asia.
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),…
Using genomic data to unravel the root of the placental mammal phylogeny.
The genome sequence assemblies of human, armadillo, elephant, and opossum are analyzed to identify informative coding indels that would serve as rare genomic changes to infer early events in placental mammal phylogeny and suggest Afrotheria and Xenarthra diverged from other placental mammals approximately 103 (95-114) million years ago.
