Abstract The remarkable fossil record of whales and dolphins (Cetacea) has made them an exemplar of macroevolution. Although their overall adaptive transition from terrestrial to fully aquatic organisms is well known, this is not true for the radiation of modern whales. Here, we explore the diversification of extant cetaceans by constructing a robust molecular phylogeny that includes 87 of 89 extant species. The phylogeny and divergence times are derived from nuclear and mitochondrial markers… Expand
A phylogenetic blueprint for a modern whale.
TLDR
This hypothesis represents a starting point for more detailed, comprehensive phylogenetic reconstructions in the future, and highlights the synergistic interaction between modern and traditional approaches that ultimately must be exploited to provide a rich understanding of evolutionary history across the entire tree of Life. Expand
Diversity versus disparity and the radiation of modern cetaceans
TLDR
It is concluded that the signature of adaptive radiations may be retained within morphological traits even after equilibrium diversity has been reached and high extinction or fluctuations in net diversification have erased any signature of an early burst of diversification in the structure of the phylogeny. Expand
Evolutionary history of the porpoises (Phocoenidae) across the speciation continuum: a mitogenome phylogeographic perspective
TLDR
It is shown that the spectacled and Burmeister’s porpoises share a more recent common ancestor than with the vaquita that diverged from southern species during the Pliocene, suggesting that the mechanism(s) driving species diversification in the relatively well-known species from the northern hemisphere may apply also to the poorly-known southern species.

  • 2018
TLDR
This present review is focused on the description and significance of newly accessible cetacean genome tools and information and their relevance in the study of the evolution of successful phenotypic adaptations associated to mammal's marine existence, and their applicability to the unresolved disease mechanisms in humans. Expand
A supermatrix analysis of genomic, morphological, and paleontological data from crown Cetacea
TLDR
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. Expand
Marine tetrapod macroevolution: Physical and biological drivers on 250 Ma of invasions and evolution in ocean ecosystems
TLDR
Placed in a broad comparative view from the Mesozoic to the Cenozoic eras, the macroevolution of marine tetrapods reveals evolutionary drivers at different scales, along with morphological parallels, unique evolutionary innovations, and the strong influence of historical constraints. Expand
A Total-Group Phylogenetic Metatree for Cetacea and the Importance of Fossil Data in Diversification Analyses.
TLDR
The metatree approach provides the most immediate route for generating higher level phylogenies of extinct taxa, and opens the door to re-evaluation of macroevolutionary hypotheses derived only from extant taxa. Expand
Higher level phylogeny of baleen whales
TLDR
The phylogenetic history of the bowhead whale has been investigated intensively using ever-increasing samples of molecular data, and by integrating this genomic information with evidence from the fossil record, divergence times can be estimated using “molecular clock” models. Expand
A Total-Group Phylogenetic Metatree for Cetacea and the Importance of Fossil Data in Diversification Analyses
TLDR
This work extends and applies a recently developed meta–analytic approach for synthesizing previously published phylogenetic studies to infer a well–resolved set of species level, time–scaled phylogenetic hypotheses for extinct and extant cetaceans (whales, dolphins and allies). Expand
Cetacea (Whales, Porpoises and Dolphins)
Cetaceans (whales and dolphins) are streamlined aquatic mammals that spend all their lives in water. They are all carnivorous, taking either many small prey by bulk filter-feeding (Mysticeti, baleenExpand

Mitogenomic analyses provide new insights into cetacean origin and evolution.
TLDR
The results suggest that the ancestors of recent cetaceans had an explosive evolutionary radiation 30-35 million years before present, and that the claimed morphological similarities between Mesonychia and Cetacea are the result of evolutionary convergence rather than common ancestry. Expand
Evolution of river dolphins
TLDR
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. Expand
Revised phylogeny of whales suggested by mitochondrial ribosomal DNA sequences
TLDR
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. Expand
Whale evolution and Oligocene southern ocean environments
TLDR
The decline of archaeocETes, further radiations of odontocetes and mysticetes, and the development of a cosmopolitan cetacean fauna in the Late Oligocene foreshadowed the radiation of modern cetACEan stocks with the establishment of major “modern” ocean patterns in the Miocene. Expand

TLDR
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. Expand
Mitochondrial phylogenetics and evolution of mysticete whales.
TLDR
The mtDNA analysis suggests that four lineages exist within the clade of Eschrichtiidae + Balaenopteridae, including a sister relationship between the humpback and fin whales, and a monophyletic group formed by the blue, sei, and Bryde's whales, each of which represents a newly recognized phylogenetic relationship in Mysticeti. Expand
Morphological and molecular evidence for a stepwise evolutionary transition from teeth to baleen in mysticete whales.
TLDR
The dramatic transformation in mysticete feeding anatomy documents an apparently rare, stepwise mode of evolution in which a composite phenotype bridged the gap between primitive and derived morphologies; a combination of fossil and molecular evidence provides a multifaceted record of this macroevolutionary pattern.

TLDR
The hypothesis that prolonged periods of global warming facilitate speciation in pelagic marine species that depend on upwelling should be tested by comparative analyses in other pelagic species. Expand
