The inferred transition from terrestrial hoofed mammal to fully aquatic cetacean has been intensively studied with fossil evidence. However, large sections of this remarkable evolutionary sequence are missing. Phylogenetic analysis of extant taxa may help to fill in some of these gaps. In this report, kappa-casein (exon 4) and beta-casein (exon 7) milk protein genes from cetaceans and other placental mammals were PCR-amplified, sequenced, and aligned to previously published sequences…

Inclusion of Cetaceans Within the Order Artiodactyla Based on Phylogenetic Analysis of Pancreatic Ribonuclease Genes

The evolution of sequence features of ribonucleases such as the distribution of positively charged amino acids and of potential glycosylation sites is described with regard to increased double-stranded RNA cleavage that is observed in several cetacean and artiodactyl RNases which may have no role in ruminants or ruminant-like digestion.

Genomic and anatomical comparisons of skin support independent adaptation to life in water by cetaceans and hippos

These results, together with histological differences in the integument and prior analyses of oxygen isotopes from stem hippopotamids (“anthracotheres”), support the hypothesis that aquatic adaptations evolved independently in hippos and cetaceans.

a Cetacea/Hippopotamidae The Blood-Clotting Protein Gene y-Fibrinogen

Competing interpretations of whale origins are tested through phylogenetic analyses of the blood-clotting protein gene y-fibrinogen from cetaceans, artiodactyls, perissodactylS (odd-toed ungulates), and carnivores (cats, dogs, and kin), which unambiguously support a hippo/whale clade and are inconsistent with the paleontological perspective.

Genetic relationships among hippopotamus, whales, and bovine based on SINE insertion analysis

Whether or not CHR-2 (hippo) homologous sequences existed at the corresponding loci of cetaceans and bovine genomes is examined.

The position of Cetacea within mammalia: phylogenetic analysis of morphological data from extinct and extant taxa.

Knowledge of the phylogenetic position of the order Cetacea (whales, dolphins, and porpoises) within Mammalia is of central importance to evolutionary biologists studying the transformations of

Phylogenetic Relationships of Extinct Cetartiodactyls: Results of Simultaneous Analyses of Molecular, Morphological, and Stratigraphic Data

Both analyses supported the exclusion of Mesonychia from Cetartiodactyla and a close phylogenetic relationship between Hippopotamidae and Cetacea, and added stratigraphic information to the intrinsic dataset, which found fewer most parsimonious trees.

Impact of increased character sampling on the phylogeny of Cetartiodactyla (Mammalia): combined analysis including fossils

The phylogenetic position of Cetacea (whales, dolphins and porpoises) is an important exemplar problem for combined data parsimony analyses because the clade is ancient and includes many well‐known

Hidden morphological support for the phylogenetic placement of Pseudoryx nghetinhensis with bovine bovids: a combined analysis of gross anatomical evidence and DNA sequences from five genes.

Combined analyses of the DNA data and published morphological evidence place Pseudoryx with Bovini (cattle and buffaloes), a subclade of Bovinae, while phylogenetic analyses of DNA sequences from five genes are used to test alternatives to the hypothesis that Pseudothyx is a close relative of Caprinae.



Molecular evidence for the inclusion of cetaceans within the order Artiodactyla.

It is estimated that the whale lineage has branched off a protoruminant lineage < 50 Mya, and the cetacean transition to aquatic life is inferred to be a relatively recent evolutionary event.

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.

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.

Evolution of the cytochrome b gene of mammals.

Comparisons of these cytochrome b sequences support current structure-function models for this membrane-spanning protein, which suggests that the outer surface which includes the Qo redox center is more constrained than the remainder of the molecule, namely, the transmembrane segments and the surface that protrudes into the mitochondrial matrix.


Abstract— Genealogical reconstructions carried out by the parsimony method on protein amino acid and DNA nucleotide sequence data are providing fresh evidence on cladistic branching patterns at

Fossil Evidence for the Origin of Aquatic Locomotion in Archaeocete Whales

The fossil indicates that archaic whales swam by undulating their vertebral column, thus forcing their feet up and down in a way similar to modern otters.

Rapid cladogenesis among the pecoran ruminants: Evidence from mitochondrial dna sequences

Phylogenetic analysis of mitochondrial DNA sequences provided no robust patterns of relationship for the four families of pecoran ruminants studied, consistent with the hypothesis that the peCoran families resulted from a rapid radiation in the Early Miocene to Late Oligocene.


In one locality, in a series of deposits ranging in age from Upper Miocene to Lower Pleistocene, may be found almost the complete phylogenetic history of the Suidae, from the most primitive, undifferentiated types to the very advanced, highly specialized genera.
