The Ctenophore Genome and the Evolutionary Origins of Neural Systems
We present the draft genome of Pleurobrachia bachei, Pacific sea gooseberry, together with ten other ctenophore transcriptomes, and show that they are remarkably distinct from other animal genomes in their content of neurogenic, immune and developmental genes. Expand

Evidence from 18S ribosomal DNA that the lophophorates are protostome animals
The suspension-feeding metazoan subkingdom Lophophorata exhibits characteristics of both deuterostomes and protostomes. Because the morphology and embryology of lophophorates are phylogeneticallyExpand

Phylogenomics reveals deep molluscan relationships
Evolutionary relationships among the eight major lineages of Mollusca have remained unresolved despite their diversity and importance. Previous investigations of molluscan phylogeny, based primarilyExpand

Annelid phylogeny and the status of Sipuncula and Echiura
BackgroundAnnelida comprises an ancient and ecologically important animal phylum with over 16,500 described species and members are the dominant macrofauna of the deep sea. Traditionally, two majorExpand

Species boundaries and global biogeography of the Alexandrium tamarense complex (Dinophyceae) 1
Alexandrium catenella (Whedon et Kof.) Balech, A. tamarense (M. Lebour) Balech, and A. fundyense Balech comprise the A. tamarense complex, dinoflagellates responsible for paralytic shellfishExpand

Illuminating the base of the annelid tree using transcriptomics.
Annelida is one of three animal groups possessing segmentation and is central in considerations about the evolution of different character traits. It has even been proposed that the bilaterianExpand

Phylogeography of the ocean quahog (Arctica islandica): influences of paleoclimate on genetic diversity and species range
Abstract The ocean quahog, Arctica islandica (Linnaeus, 1767), is a commercially important bivalve found on continental shelves throughout much of the North Atlantic. To assess genetic subdivision inExpand

Open‐ocean barriers to dispersal: a test case with the Antarctic Polar Front and the ribbon worm Parborlasia corrugatus (Nemertea: Lineidae)
Open‐ocean environments provide few obvious barriers to the dispersal of marine organisms. Major currents and/or environmental gradients potentially impede gene flow. One system hypothesized to formExpand

Error, signal, and the placement of Ctenophora sister to all other animals
Significance Traditional interpretation of animal phylogeny suggests traits, such as mesoderm, muscles, and neurons, evolved only once given the assumed placement of sponges as sister to all otherExpand

Multiple lineages and absence of panmixia in the “circumpolar” crinoid Promachocrinus kerguelensis from the Atlantic sector of Antarctica
Despite considerable interest in physiology, evolution and life history of Antarctic marine invertebrates, only a limited number of studies have examined the genetic variability and diversityExpand
