They can be seen as precursors to the evolution of a brain (B), marking a transition from simpler nerve nets to more centralized and complex nervous systems (C). This evolution likely occurred as animal behaviors became more complex (D), necessitating more sophisticated neural structures for processing sensory information and coordinating responses.
