Despite the biological and economic importance of the Cetartiodactyla, the phylogeny of this clade remains controversial. Using the supertree approach of matrix representation with parsimony, we present the first phylogeny to include all 290 extant species of the Cetacea (whales and dolphins) and Artiodactyla (even‐toed hoofed mammals). At the family‐level, the supertree is fully resolved. For example, the relationships among the Ruminantia appear as (((Cervidae, Moschidae) Bovidae) (Giraffidae… 
A comprehensive phylogeny of extant horses, rhinos and tapirs (Perissodactyla) through data combination
The first phylogenies to include all extant species of Perissodactyla (oddtoed hoofed mammals) and the recently extinct quagga are presented and the contentious affinity of the Sumatran rhino is resolved in favour of it forming a clade with the two Asian rhinos.
A supermatrix analysis of genomic, morphological, and paleontological data from crown Cetacea
The parsimony analysis of the supermatrix and the analysis of morphology constrained to fit the ML/Bayesian molecular tree yielded broadly congruent phylogenetic hypotheses, implying that many character states shared by river dolphins evolved in their oceanic ancestors, contradicting the hypothesis that these characters are convergent adaptations to fluvial habitats.
Radiation of Extant Cetaceans Driven by Restructuring of the Oceans
It is found that the toothed whales are monophyletic, suggesting that echolocation evolved only once early in that lineage some 36–34 Ma, and support is found for increased diversification rates during periods of pronounced physical restructuring of the oceans.
The Nasal Complex of a Semiaquatic Artiodactyl, the Moose (Alces alces): Is it a Good Evolutionary Model for the Ancestors of Cetaceans?
There is little evidence that the early ancestors of cetaceans engaged in prolonged bouts of diving for aquatic foods but more probably were surface swimmers traveling between terrestrial food sources or fleeing predators.
Fragilicetus velponi: a new mysticete genus and species and its implications for the origin of Balaenopteridae (Mammalia, Cetacea, Mysticeti)
The character combination exhibited by this cetacean provides important information about the assembly of the specialized morphological features responsible for the highly efficient prey capture mechanics of Balaenopteridae.
How to contend with paraphyly in the taxonomy of the delphinine cetaceans
Until molecular and/or morphological analyses adequately sort out relationships in this very recently radiated group, one possible solution indeed would be to merge all the delphinine genera with Delphinus, and implications of such a move and alternatives are discussed.

Killer sperm whale: a new basal physeteroid (Mammalia, Cetacea) from the Late Miocene of Italy
Large body size, large teeth present in both lower and upper jaw, and anteroposteriorly elongated temporal fossa and zygomatic process of the squamosal indicate that this cetacean was an active predator adapted to feeding on large prey, similarly to the extant killer whale.
A higher-level MRP supertree of placental mammals
The supertree is the first phylogeny to include all 113 extant families without making a priori assumptions of suprafamilial monophyly, and supports the idea that biogeography has played a crucial role in the evolution of placental mammals.


Molecular evidence from retroposons that whales form a clade within even-toed ungulates
An extensive survey of retropositional events that might have occurred during the divergence of whales and even-toed ungulates is made, providing evidence that whales, ruminants and hippopotamuses form a monophyletic group.
Retroposon analysis of major cetacean lineages: The monophyly of toothed whales and the paraphyly of river dolphins
The combination of SINE and flanking sequence analysis suggests a topology and set of divergence times for odontocete relationships, offering alternative explanations for several long-standing problems in cetacean evolution.
The Phylogenetic Position of Cetaceans: Further Combined Data Analyses, Comparisons with the Stratigraphic Record and a Discussion of Character Optimization1
A previous total evidence analysis of the position of cetaceans was updated by adding several hundred new informative molecular characters from the literature, finding that all most parsimonious trees indicate a paraphyletic Artiodactyla with conflict existing over the exact sister taxon of Cetacea.
Phylogeny of all major groups of cetaceans based on DNA sequences from three mitochondrial genes.
A molecular phylogeny based on 1,352 base pairs of two mitochondrial ribosomal gene segments and the mitochondrial cytochrome b gene for all major groups of cetaceans contradicts this long-accepted taxonomic subdivision and suggests a more recent origin of baleen whales than has been previously assumed.
Evidence from the digestive tract on phylogenetic relationships in ungulates and whales
Following consideration of 20 morphological parameters of the gastrointestinal tract of ungulates and Cetacea, phylogenetic trees were constructed for baleen whales, toothed whales and beaked whales, as well as for four taxa of the PSHM group.
Evolution of river dolphins
It is suggested that ancestors of the four extant river dolphin lineages colonized the shallow epicontinental seas that inundated the Amazon, Paraná, Yangtze and Indo–Gangetic river basins, subsequently remaining in these extensive waterways during their transition to freshwater with the Late Neogene trend of sea–level lowering.
Influence of alignment on the mtDNA phylogeny of Cetacea: questionable support for a Mysticeti/Physeteroidea clade.
Cetacea has traditionally been divided into Odontoceti, the toothed whales, and Mysticeti, the baleen whales. These groups have been considered monophy? letic, although their origins and age have
Phylogenetic relationships among the true porpoises (Cetacea:Phocoenidae).
Portions of the cytochrome b gene and control region of the mitochondrial DNA molecule were sequenced to investigate systematic relationships among the six extant species of true porpoises, (Cetacea:
Revised phylogeny of whales suggested by mitochondrial ribosomal DNA sequences
The determination of DNA sequences from two mitochondrial ribosomal gene segments for 16 species of cetaceans, a perissodactyl and a sloth, are reported and the first phylogeny for whales and dolphins based on explicit cladistic methods is constructed, confirming that cetACEans are closely related to artiodactyls and that all families and superfamilies of cetus are monophyletic.
Origin and radiation of Southern Hemisphere coastal dolphins (genus Cephalorhynchus)
The hypothesis that Cephalorhynchus is a monophyletic genus or that the four species have arisen separately from pelagic Lissodelphine species and have converged morphologically is investigated, and a pattern of radiation by colonization is proposed.
