Background Integration of diverse data (molecules, fossils) provides the most robust test of the phylogeny of cetaceans. Positioning key fossils is critical for reconstructing the character change from life on land to life in the water. Methodology/Principal Findings We reexamine relationships of critical extinct taxa that impact our understanding of the origin of Cetacea. We do this in the context of the largest total evidence analysis of morphological and molecular information for… 

Figures and Tables from this paper

A supermatrix analysis of genomic, morphological, and paleontological data from crown Cetacea

Analysis of the supermatrix and the analysis of morphology constrained to fit the ML/ Bayesian molecular tree yielded broadly congruent phylogenetic hypotheses, suggesting that these two clades radiated in the late Oligocene or later, contra some recent reports.

Total‐evidence approach reveals an extinct lineage of Paederinae rove beetles from Cretaceous Burmese amber

The analysis reveals an extinct lineage of Paederinae rove beetles with a suite of unique morphological characters, resulting in the description of a new genus: Diminudon gen. nov, which may represent an additional case for miniaturization in the Cretaceous.

An Anatomical and Phylogenetic Study of the Osteology of the Petrosal of Extant and Extinct Artiodactylans (Mammalia) and Relatives

It is shown that in many ways the osteology of the hippopotamid ear resembles that of certain stem cetaceamorphans more than it resembles the ear regions of suines (pigs and peccaries), and shortest trees indicate that these similarities are convergent.

Exemplar species from the four major extant terrestrial and semiaquatic artiodactyla clades are described and the anatomy of the ear region with the auditory bulla both in place and removed and the basicranium is illustrated.

Phylogenomic Analysis Resolves the Interordinal Relationships and Rapid Diversification of the Laurasiatherian Mammals

Pegasoferae (Perissodactyla + Carnivora + Pholidota + Chiroptera) does not appear to be a natural group and Divergence time estimates were similar to those of several studies and suggest that the divergences among these orders occurred within just a few million years.

Phylogenetic Status and Timescale for the Diversification of Steno and Sotalia Dolphins

It is hypothesised that the timing of separation of the marine and Amazonian Sotalia species (2.3 Ma) coincided with the establishment of the modern Amazon River basin and it is concluded that Orcinus does not belong in the Globicephalinae, but Orcaella may be part of that subfamily.

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.

Ecological evolution of early Cetartiodactyla and reconstruction of its missing initial link

The analysis of biodiversity and ecological evolution of Eocene Cetartiodactyla against the background of changes in the biosphere, biota, and paleogeography has provided a model for the origin,



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

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.

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.

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.

Molecular phylogenetics and the origins of placental mammals

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.

New Morphological Evidence for the Phylogeny of Artiodactyla, Cetacea, and Mesonychidae

Abstract Parsimony-based analyses of a data set including 68 taxa coded for 186 morphological characters corroborate monophyly of Artiodactyla (even-toed ungulates), Suiformes (hippos, pigs,

Phylogenetic relationships of artiodactyls and cetaceans as deduced from the comparison of cytochrome b and 12S rRNA mitochondrial sequences.

The combined analysis of the two genes suggests a monophyletic Cetacea +Artiodactyla clade, whereas PerissodactylA, Carnivora, and Tethytheria fall outside this clade.

Skeletons of terrestrial cetaceans and the relationship of whales to artiodactyls

Cladistic analysis of the skeletons of two early Eocene pakicetid cetaceans, the fox-sized Ichthyolestes pinfoldi, and the wolf-sized Pakicetus attocki, indicates that cetACEans are more closely related to artiodactyls than to any mesonychian, and supports monophyly of artiodACTyls.

Relationships of Endemic African Mammals and Their Fossil Relatives Based on Morphological and Molecular Evidence

Analyses of anatomical and DNA sequence data run on a parallel supercomputer that include fossil taxa support the inclusion of tenrecs and golden moles in the Afrotheria, an endemic African clade of placental mammals, and support the position of AfroTheria as well-nested, not basal, within Placentalia.
