The term “primate” refers to a group of mammals that includes humans, apes, monkeys, and prosimians (like lemurs and tarsiers). Primates share several key characteristics:

  1. Highly developed brains: Primates generally have larger brains relative to their body size compared to most other mammals.
  2. Forward-facing eyes: This gives them better depth perception, which is important for activities like jumping or grabbing objects.
  3. Opposable thumbs: This feature allows them to grasp and manipulate objects, aiding in tool use and foraging.
  4. Social behavior: Many primates live in complex social groups and exhibit a variety of social behaviors.
  5. Flexible limbs: Most primates have a high degree of limb mobility, especially in their hands and feet.

Primates are divided into two main subgroups: Strepsirrhines (like lemurs) and Haplorhines (which include monkeys, apes, and humans). Humans are part of the great apes, along with orangutans, gorillas, chimpanzees, and bonobos.
