Primate
Primate
Primate (/ˈpraɪmeɪt/ from Latin primat-, from primus 'first') is a mammalian order that includes humans, apes, monkeys, and prosimians such as lemurs and tarsiers.
Etymology
The term "primate" comes from the Latin primat-, from primus meaning 'first'. This refers to the belief that primates are the "first" or highest order of mammals.
Classification
Primates are classified into two main groups: Prosimii and Anthropoidea. Prosimii includes the more primitive primates such as lemurs and tarsiers, while Anthropoidea includes monkeys, apes, and humans.
Characteristics
Primates are characterized by their highly flexible limbs, opposable thumbs, and large brains relative to body size. They also have a highly developed binocular vision, which allows them to perceive depth and distance accurately.
Evolution
The evolution of primates is a topic of ongoing research. It is believed that primates evolved from small, insect-eating mammals during the Cretaceous period, around 85 million years ago.
