Taxonomic Classification: Mammals and Primates Flashcards

A set of vocabulary flashcards defining key taxonomic groups, physical adaptations, and mammalian characteristics discussed in the lecture notes.

Class Mammalia

A taxonomic class of vertebrate animals characterized by having hair or fur, being warm-blooded, breathing with lungs, having a backbone, giving live birth to young (with few exceptions), and having females with mammary glands that produce milk to nourish their offspring.

Order Primates

A specialized order of mammals characterized by adaptations such as opposable thumbs, fingernails instead of claws, forward-facing eyes with binocular vision, large highly developed brains, and flexible shoulders and arms.

Opposable Thumbs

A specialized feature of Order Primates that allows the thumb to touch every finger on the same hand, enabling the ability to grasp and hold objects, write, climb, and use tools.

Binocular Vision

Three-dimensional (3D) vision resulting from forward-facing eyes, which provides excellent depth perception in primates.

Mammary Glands

Organs found in female mammals that produce milk to nourish their babies.

Warm-blooded

The biological capability of an organism to maintain a constant internal body temperature regardless of external environment, a defining trait of Class Mammalia.

Platypus and Echidna

Mammals specifically noted as exceptions to the general rule that mammals give live birth.

Order Carnivora

The taxonomic order to which dogs belong, distinguishing them from mammals in Order Primates due to traits like having claws instead of flat fingernails and lacking opposable thumbs.

Taxonomic Classification

The system of grouping and organizing living organisms based on shared physical and biological characteristics to demonstrate life's diversity and evolutionary relationships.
