Primates

A diverse order of mammals that includes monkeys, apes, and humans.

Taxonomic groupings

The classification of living organisms into hierarchical groups based on shared characteristics.

Prosimii

Suborder of primates that includes lemurs, lorises, and tarsiers, known for characteristics such as reliance on olfaction.

Strepsirhini

A suborder of primates that includes lemurs and lorises, characterized by a moist nose and unfused mandible.

Tapetum lucidum

A reflective layer behind the retina that enhances night vision in nocturnal animals.

Lemuriformes

An infraorder of primates that includes all lemurs.

Haplorhini

A suborder of primates that comprises tarsiers, monkeys, and apes, known for having a more advanced visual system.

Platyrrhini

Infraorder of New World monkeys, characterized by flat noses and mostly arboreal lifestyles.

Catarrhini

Infraorder of Old World monkeys and apes, defined by narrow noses and greater reliance on eyesight than smell.

Prosimii vs Anthropoidea

Comparison of two suborders of primates, highlighting differences like postorbital plates and reliance on olfaction.

Bilophodonty

A dental pattern characteristic of Old World monkeys, where upper molars have two cusps.

Y-5 molars

A dental pattern observed in hominoids (apes and humans) characterized by five cusps arranged in a Y shape.

Colobinae

Subfamily of Old World monkeys that primarily eat leaves and have complex stomachs for digestion.

Cercopithecinae

Subfamily of Old World monkeys characterized by diverse diets and social structures.

Hominoidea

Superfamily that includes apes and humans, characterized by larger brains and absence of tails.

Hylobatidae

Family of small apes known as gibbons, living in Southeast Asia and known for brachiation.

Pongidae

Formerly a family that included orangutans, now reclassified as part of Hominidae.

Hominidae

Family of great apes and humans, including gorillas, chimpanzees, bonobos, and humans.

Fission-fusion dynamics

A social structure in which groups divide and merge fluidly, often seen in chimpanzees.

Tarsioidea

An infraorder of primates that includes tarsiers, known for their unique adaptations like large eyes.
