Insights into bilaterian evolution from three spiralian genomes

Comparative analysis of the genomes of one mollusc (Lottia gigantea) and two annelids (Capitella teleta and Helobdella robusta) enable a more complete reconstruction of genomic features of the last common ancestors of protostomes, bilaterians and metazoans; against this conserved background they provide the first glimpse into lineage-specific evolution and diversity of the lophotrochozoans. This paper presents the draft genome sequences of two annelids — a freshwater leech (Helobdella robusta) and a bristly, segmented marine worm (Capitella teleta) — and a mollusc, the owl limpet (Lottia gigantea). These two phyla account for nearly one-third of known marine species and are of importance both ecologically and…
