Recent fieldwork suggests that the social structures of the spotted hyena are every bit as complex as those of baboons, and CT scans have confirmed that hyena brains have evolved in a similar frontal direction to primates, with the region involved in complex decision-making enlarged. [36] The secretions are primarily used for territorial marking, though both the aardwolf[7] and the striped hyena[37] will spray them when attacked.
