The Ctenophore Genome and the Evolutionary Origins of Neural Systems
TLDR
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

The Magnitude of Global Marine Species Diversity
BACKGROUND The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register ofExpand

Evolution of the chordate body plan: new insights from phylogenetic analyses of deuterostome phyla.
The deuterostome phyla include Echinodermata, Hemichordata, and Chordata. Chordata is composed of three subphyla, Vertebrata, Cephalochordata (Branchiostoma), and Urochordata (Tunicata). CarefulExpand

Evaluating hypotheses of deuterostome phylogeny and chordate evolution with new LSU and SSU ribosomal DNA data.
We investigated evolutionary relationships among deuterostome subgroups by obtaining nearly complete large-subunit ribosomal RNA (LSU rRNA)-gene sequences for 14 deuterostomes and 3 protostomes andExpand

Urochordates are monophyletic within the deuterostomes.
Understanding the phylogenetic relationships of the three major urochordate groups within the deuterostomes is central to understanding the evolution of the chordates. We have prepared a detailedExpand

The origin and evolution of animal appendages.
Animals have evolved diverse appendages adapted for locomotion, feeding and other functions. The genetics underlying appendage formation are best understood in insects and vertebrates. The expressionExpand

Molecular phylogeny of the protochordates: chordate evolution
The deuterostomes are a monophyletic group of multicellular animals that include the Chordata, a phylum that exhibits a unique body plan within the metazoans. Deuterostomes classically containedExpand

Coloniality has evolved once in Stolidobranch Ascidians.
Ascidians exhibit a rich array of body plans and life history strategies. Colonial species typically consist of zooids embedded in a common test and brood large, fully developed larvae, whileExpand
