Enhanced: The Ups and Downs of a Sea Anemone

Peter Holland

Bilateral symmetry is thought to have emerged after the evolutionary split between cnidarians and bilaterians. In his Perspective, Holland discusses whether bilateral symmetry has an earlier evolutionary origin. New gene expression analyses in the starlet sea anemone suggest that bilateral symmetry may be homologous between sea anemones and bilaterians (Finnerty et al.).
