As much as one-third of marine life, including clams, octupuses and worms, fall into a group called the lophotrochozoa, ancient creatues that originated more than 500 million years ago. Berkeley’s Daniel Rokhsar spearheaded a team that has now sequenced the genomes of 3 of these creatures, a limpet, a polychaete worm and a freshwater leech, to learn more about their evolution.
