Cetaceans, the whales, dolphins and porpoises, are a taxonomically and structurally diverse
clade of aquatic mammals whose specialised farm and habits obscure their distant origins …

Despite the biological and economic importance of the Cetartiodactyla, the phylogeny of this
clade remains controversial. Using the supertree approach of matrix representation with …

Alligatoroidea, a stem-based group including living alligators and caimans and all taxa
closer to them than to Crocodylus or Gavialis, includes seven living species and a large …

Cetaceans are remarkable among mammals for their numerous adaptations to an entirely
aquatic existence, yet many aspects of their phylogeny remain unresolved. Here we merged …

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 …

Cetaceans form one of the most unique groups in the evolutionary history of mammals. They
have returned to the sea and modified their tail as an efficient means of locomotion. As they …

The copepod Eurytemora affinis has a broad geographic range within the Northern
Hemisphere, inhabiting coastal regions of North America, Asia, and Europe. A phylogenetic …

Background Cetacea (dolphins, porpoises, and whales) is a clade of aquatic species that
includes the most massive, deepest diving, and largest brained mammals. Understanding …

The origin of baleen in mysticete whales represents a major transition in the phylogenetic
history of Cetacea. This key specialization, a keratinous sieve that enables filter-feeding …

Tests for incongruence as an indicator of among-data partition conflict have played an
important role in conditional data combination. When such tests reveal significant …
