Changes in Homeotic (Hox) gene regulation have long been thought to drive the evolution of animal body plans. Direct genetic evidence of their evolutionary role has, however, remained limited. A new study reveals how several mutations distributed across a gene network mask the phenotypic effects of a Hox gene's evolution.
