Primates are a group of mammals that includes humans, apes, monkeys, and prosimians. They are characterized by their advanced cognitive abilities, flexible limbs, and forward-facing eyes. Primates are found in various habitats around the world, and they exhibit a wide range of behaviors and social structures.
Classification of Primates
Primates are classified into two suborders: Prosimii (or prosimians) and Anthropoidea (or anthropoids).
Prosimii: This group includes lemurs, lorises, and tarsiers. They are typically smaller in size and have characteristics that are more primitive compared to anthropoids.
Anthropoidea: This group includes monkeys, apes, and humans. They are generally larger in size and have more advanced cognitive abilities.
Characteristics of Primates
Some key characteristics of primates include:
Opposable thumbs: Most primates have opposable thumbs, which allow them to grasp and manipulate objects with precision.
Binocular vision: Primates have forward-facing eyes, which provide them with depth perception and improved visual acuity.
Large brain relative to body size: Primates have relatively large brains compared to other mammals, which is associated with their advanced cognitive abilities.
From Molecules to Organisms: Structures and Processes
Obtain, evaluate, and communicate information to describe the function and diversity of organelles and structures in various types of cells (e.g., muscle cells having a large amount of mitochondria, plasmids in bacteria, chloroplasts in plant cells).
