Final answer:
Primates, as part of their maturation and behavior, are characterized by large brains, extended periods of development for learning, and a reliance on vision over smell. They exhibit complex social behaviors and live in groups.
Step-by-step explanation:
Regarding aspects of primate maturation, learning, and behavior, primates exhibit several unique characteristics, except for a reliance on the sense of smell which is less compared to other mammals. Primates are known for their large cerebrum and social behaviors, contributing significantly to sensory analysis, motor behavior, and social interactions. They have relatively long lifespans and prolonged developmental periods that allow extensive learning opportunities for their young. Moreover, their social structures are complex and they typically live in groups. Unlike other mammals, primates rely heavily on their vision and less on olfactory senses, with many species capable of color vision and having a three-dimensional vision due to their forward-facing eyes.
