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
Students who demonstrate understanding can:
Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.
Heredity: Inheritance and Variation of Traits
Students who demonstrate understanding can:
Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
