The potential weaknesses of limited character and taxon sampling are addressed in a comprehensive molecular phylogenetic analysis of 64 species sampled across all extant orders of placental mammals, providing new insight into the pattern of the early placental mammal radiation.
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.
The Late Miocene Radiation of Modern Felidae: A Genetic Assessment
The phylogenetic performance of distinct gene classes showed that Y-chromosome segments are appreciably more informative than mitochondrial DNA, X-linked, or autosomal genes in resolving the rapid Felidae species radiation.
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 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.
Pattern and timing of diversification of the mammalian order Carnivora inferred from multiple nuclear gene sequences.
Molecular dating and biogeography of the early placental mammal radiation.
An integrated genomic, paleontological, and biogeographic hypothesis is proposed to account for these earliest splits on the placental mammal family tree and address current discrepancies between fossil and molecular evidence.

The genetic diversity, population structure and demographic history of jaguars across their geographical range are investigated by analysing 715 base pairs of the mitochondrial DNA (mtDNA) control region and 29 microsatellite loci in ≈40 individuals sampled from Mexico to southern Brazil.
