Radiation of Extant Cetaceans Driven by Restructuring of the Oceans
TLDR
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. Expand
On the Origin of a Novel Parasitic-Feeding Mode within Suspension-Feeding Barnacles
TLDR
A phylogenetic analysis based on ribosomal DNA data from 99 selected barnacle species shows that Anelasma squalicola is most closely related (sister taxon) to the pedunculate barnacle Capitulum mitella, which provides the evolutionary framework to explain the unprecedented transition from a filter-feeding barnacle to a parasitic mode of life.

Bayesian Inference of the Metazoan Phylogeny A Combined Molecular and Morphological Approach
TLDR
This work presents the first statistically founded analysis of a metazoan data set based on a combination of morphological and molecular data and compares the results with a traditional parsimony analysis. Expand
Molecular phylogeny of the Branchiopoda (Crustacea)--multiple approaches suggest a 'diplostracan' ancestry of the Notostraca.
TLDR
The phylogeny of Branchiopoda is examined by using two genes, mitochondrial 16S rRNA and nuclear 28S r RNA, which previously have seen little use for inferring branchiopod phylogeny, and a case is made for a possible diplostracan ingroup position of Notostraca. Expand
First maxillae suction discs in Branchiura (Crustacea): development and evolution in light of the first molecular phylogeny of Branchiura, Pentastomida, and other "Maxillopoda".
TLDR
Based on the molecular phylogeny a likely evolutionary scenario is that the ancestral branchiuran used hooks (on the first maxilla) for attachment, as seen in Dolops, of which the proximal part was subsequently modified into suction discs in Argulus and Chonopeltis (and Dipteropeltais). Expand
Cladistic analysis of the Cirripedia Thoracica
TLDR
A cladistic analysis of the Cirripedia Thoracica using morphological characters and the Acrothoracica and Ascothoracida as outgroups reveals that several key questions in cirripede phylogeny remain unsolved, notably the position of shell-less forms and the transition from `pedunculate' to `sessile' barnacles. Expand
New data from an enigmatic phylum: evidence from molecular sequence data supports a sister‐group relationship between Loricifera and Nematomorpha
TLDR
The results imply that a revision of the conception of early ecdysozoan evolution is required and suggest that evolution through progenesis (sexual maturation of larvae) may have played an important role among the ancestral cycloneuralians. Expand
The Origin of Insects
Recent molecular evidence suggests that crustaceans may have successfully invaded land as insects.
MOLECULAR AND MORPHOLOGICAL EVIDENCE FOR A MONOPHYLETIC CLADE OF ASEXUALLY REPRODUCING RHIZOCEPHALA: POLYASCUS, NEW GENUS (CIRRIPEDIA)
TLDR
A new genus is established, Polyascus, to accommodate three members of this clade of parasitic crustaceans that exclusively parasitize other Crustacea which also share a number of common morphological features. Expand
