Developmental studies in sound-producing fishes and tetrapods indicate that central pattern generating networks dedicated to vocalization originate from the same caudal hindbrain rhombomere (rh) 8-spinal compartment. Together, the evidence suggests that vocalization and its morphophysiological basis, including mechanisms of vocal-respiratory coupling that are widespread among tetrapods, are ancestral characters for bony vertebrates. Premotor-motor circuitry for pectoral appendages that function in locomotion and acoustic signaling develops in the same rh8-spinal compartment. Hence, vocal and pectoral phenotypes in fishes share both developmental origins and roles iProceedings of the National Academy of Sciences of the United States of AmericaShared developmental and evolutionary origins for neural basis of vocal-acoustic and pectoral-gestural signaling.PMC3386879DC00092R01 DC000092Bass AHChagnaud BPfalseShared developmental and evolutionary origins for neural basis of vocal-acoustic and pectoral-gestural signaling.Acoustic signaling behaviors are widespread among bony vertebrates, which include the majority of living fishes and tetrapods.
