Aunque se ha considerado que las CCNson una innovacion exclusiva de los vertebrados, Shimeld y Holland (10) y Holland y Holland (24) argumentaron que esta afirmacion resulta controversial ya que estudios en anfioxos y ascidias (agnatos) han resultado positivos para estructuras homologas, por lo que el potencial para la diferenciacion de estas poblaciones de celulas ya se encontraba presente en un antecesor de los vertebrados.
