Abstract Considerable long-standing controversy and confusion surround the phylogenetic affinities of pinnipeds, the largely marine group of “fin-footed” members of the placental mammalian order Carnivora. Until most recently, the two major competing hypotheses were that the pinnipeds have a single (monophyletic) origin from a bear-like ancestor, or that they have a dual (diphyletic) origin, with sea lions (Otariidae) derived from a bear-like ancestor, and seals (Phocidae) derived from an otter… 
Current status of pinnipeds phylogeny based on molecular and morphological data
ABSTRACT The disagreement surrounding the relationship within pinnipeds as well as their phylogenetic affinities still remains unresolved. Molecular-based studies neglect significant morphological
On the phylogeny of Mustelidae subfamilies: analysis of seventeen nuclear non-coding loci and mitochondrial complete genomes
This study brings new perspectives on the previously obscured phylogenetic relationships among Mustelidae subfamilies and provides another example demonstrating the effectiveness of nuclear non-coding loci for reconstructing evolutionary histories in a group that has undergone rapid bursts of speciation.
Phylogeny of the Procyonidae (Mammalia: Carnivora): molecules, morphology and the Great American Interchange.
Mitogenomic analyses of caniform relationships.
Phylogenetic utility of nuclear introns in interfamilial relationships of Caniformia (order Carnivora).
The present study resolves some of the ambiguous relationships in Caniformia phylogeny and shows that the noncoding nuclear markers can offer powerful complementary data for estimating the species tree and the powers and pitfalls of phylogenetics using nuclear introns as markers are discussed.
A Total Evidence Phylogenetic Analysis of Pinniped Phylogeny and the Possibility of Parallel Evolution Within a Monophyletic Framework
Results suggest the pinniped stem may be expanded to include additional fossil arctoid taxa, including Puijila, Potamotherium, and Kolponomos, and provide further support for prolonged freshwater and nearshore phases in the Evolution of pinnipeds, prior to the evolution of the extreme level of aquatic adaptation displayed by extant taxa.
Deciphering and dating the red panda's ancestry and early adaptive radiation of Musteloidea.
Pinniped phylogenetic relationships inferred using AFLP markers
Although supporting the existing ideas about pinniped relationships, the data shed light on relationships within the hitherto relatively unresolved Phocine species group, and provide further supporting evidence for raising two subspecies of Zalophus californianus and Z. c.

Phylogenetic positions for fossil taxa indicate that several taxa previously described as early members of extant families (e.g., Bathygale and Plesictis) are likely stem taxa at the base of the Arctoidea.


Phylogenetic relationships within mammalian order Carnivora indicated by sequences of two nuclear DNA genes.
Phylogenetic relationships within caniform carnivores based on analyses of the mitochondrial 12S rRNA gene
The complete 12S rRNA gene of 32 carnivore species, including four feliforms and 28 caniforms, was sequenced and showed an unresolved polytomy of the basic caniform clades; pinnipeds, mustelids, procyonids, skunks, Ailurus (lesser panda), ursids, and canids, indicating a major diversification ofCaniforms during a relatively short period of time.
Phylogenetic analyses of complete cytochromeb genes of the order Carnivora with particular emphasis on the Caniformia
The analysis shows that the skunks are only distantly related to remaining mustelids (Mustelidae sensu stricto) and that the family Mustelidae, including the skunk, is paraphyletic, suggesting an evolutionary separation within a relatively short period of time.
Phylogenetic Relationships and Divergence Times among Mustelids (Mammalia: Carnivora) Based on Nucleotide Sequences of the Nuclear Interphotoreceptor Retinoid Binding Protein and Mitochondrial Cytochrome b Genes
The low level of sequence divergence in cytochrome b between Mustela lutreola and Putorius is therefore a result of interspecific mitochondrial introgression between these taxa, rather than a recent origin of Mustelinae in a close relationship to Putorius.
Molecular phylogeny of the carnivora (mammalia): assessing the impact of increased sampling on resolving enigmatic relationships.
This study analyzed 76 species of Carnivora using a concatenated sequence of 6243 bp from six genes, representing the most comprehensive sampling yet undertaken for reconstructing the phylogeny of this clade.
A Phylogenetic View on Species Radiation in Apodemus Inferred from Variation of Nuclear and Mitochondrial Genes
It was shown that these four lineages diverged within a short period of evolutionary time, suggestive of a radiation event and may have a correlation with the notion that deciduous broadleaf forests remained in Central East Asia through the late Tertiary to the present, while those in Europe to a large extent had disappeared by the Pliocene.
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.
A molecular phylogeny of the family Mustelidae (Mammalia, Carnivora), based on comparison of mitochondrial cytochrome b nucleotide sequences.
The molecular phylogenetic tree indicated a clear separation of five genera: Mustela and Martes from the subfamily Mustelinae, Lutra and Enhydra from thesubfamily Lutrinae, and Meles fromThe subfamily Melinae.
Mitogenomic analyses of eutherian relationships
The study corroborated recent findings that have identified a sister-group relationship between Anthropoidea and Dermoptera (flying lemurs), thereby making their own order, Primates, a paraphyletic assembly.
