A mutualistic relationship is described as when two organisms of different species work together and both benefit from the relationship.
Answer:
Therapsids were "mammal-like" reptiles and are ancestors to the mammals, including humans, found today. One group of therapsids is called dicynodonts. All species of dicynodonts were herbivores (plant eaters) and their sizes ranged from small burrowers to large browsers.
Mammals evolved from a group of reptiles called the synapsids. These reptiles arose during the Pennsylvanian Period (310 to 275 million years ago). It was over millions of years that some of these therapsids would evolve many features that would later be associated with mammals.
