Description : What is the evolutionary advantage of the occurrence of sperm cells and larval stage in the life cycle of sponges?
Last Answer : The sexual reproduction in sponges, in addition to contributing to genetic variability, also facilitates the colonization of farther environments by these beings, since sperm cells and larvae are mobile and can swim in the exterior to compensate the immobility of the adult individual.
