Mammalian mitogenomic relationships and the root of the eutherian tree
A mitogenomic study based on the set of protein-coding genes from complete mt genomes of 60 mammalian species finds that the previously unrepresented order Dermoptera (flying lemurs) fell within Primates as the sister group of Anthropoidea, making Primates paraphyletic. Expand
Marsupial relationships and a timeline for marsupial radiation in South Gondwana.
The results suggest that marsupials colonized Australia twice from Antarctica/South America and that the divergence between Microbiotheria and its Australian relatives coincided with the geological separation of Antarctica and Australia. Expand
Tracking Marsupial Evolution Using Archaic Genomic Retroposon Insertions
Genome-wide comparisons of shared retroposon insertion patterns resolve the phylogeny of marsupials, clearly distinguishing South American and Australian species and lending support toExpand
Phylogenomic data analyses provide evidence that Xenarthra and Afrotheria are sister groups.
The phylogenetic analysis joined Xenarthra and Afrotheria on a common branch, Atlantogenata, and this topology was found to fit the data significantly better than the alternative trees, and exceeds by a considerable margin that of any previous study. Expand
Radiation of Extant Marsupials After the K/T Boundary: Evidence from Complete Mitochondrial Genomes
Molecular estimates suggest that the deepest marsupial divergences took place 64–62 million years before present (MYBP), implying that the radiation of recent marsupials took place after the K/T (Cretaceous/Tertiary) boundary. Expand
The evolutionary history of bears is characterized by gene flow across species
A genome analysis of the bear family with representatives of all living species shows that gene flow is not limited to closely related species pairs and necessitates shifting the attention from speciation processes achieving genome-wide reproductive isolation to the selective processes that maintain species divergence in the face of gene flow.

Multi-locus Analyses Reveal Four Giraffe Species Instead of One
These findings provide the most inclusive analysis of giraffe relationships to date and show that their genetic complexity has been underestimated, highlighting the need for greater conservation efforts for the world's tallest mammal. Expand
Housekeeping genes for phylogenetic analysis of eutherian relationships.
The analyses of the currently established sequences have helped examination of problematic parts in the eutherian tree at the same time as they caution against suggestions that have claimed that basal eutheria relationships have been conclusively settled. Expand
Genetic signatures of adaptation revealed from transcriptome sequencing of Arctic and red foxes
Fat metabolism seems to play a central role in adaptation of Arctic foxes to the cold climate, as has been identified in the polar bear, another arctic specialist. Expand
The impact of fossil calibrations, codon positions and relaxed clocks on the divergence time estimates of the native Australian rodents (Conilurini).
The study on the problems related to estimating divergence times in fast-evolving lineages such as rodents, emphasize the choice of data and calibration points as being critical, because the divergence times can otherwise be estimated to be significantly older. Expand
