Primate Traits
opposable thumbs/divergent big toe, nails, rounder brain case, bigger brains (relative to body size), forward facing eye socket, post orbital bar-surrounds eye socket for protection, complex social groups, diurnal activity
Primates are a diverse group of mammals that belong to the order Primates. They are characterized by a number of physical and behavioral traits that set them apart from other mammals.
1. Forward-facing eyes – Primates have binocular vision due to the position of their eyes, which enables depth perception and better judging of distances.
2. Grasping hands and feet – Primates have opposable thumbs and/or big toes that are able to grasp objects, branches, or food, which allows them to move easily through the rainforest canopy.
3. Enlarged brains – Primates have larger brain size relative to their body size than other mammals, which allows them to process complex social interactions.
4. Parental care – Most primates exhibit high levels of maternal investment in offspring, which includes long periods of nursing and carrying as well as grooming and socializing.
5. Social behavior – Primates live in complex social groups with flexible hierarchies. They exhibit a range of behaviors including grooming, vocalization, and varying degrees of altruism, cooperation, and competition.
6. Enhanced sensory system – Primates depend heavily on visual and tactile senses for foraging, communication, and navigating through their environment.
Overall, these primate traits have been advantageous for living in arboreal environments from which they have adapted to live in other habitats as well.
