Study Notes

Taxonomy and Classification

Taxonomy is the scientific discipline focused on the classification of living organisms.
The hierarchy of classification, from broadest to most specific, includes Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Classification of animals primarily utilizes Greek or Latin terminology.

Phylogeny

Phylogeny refers to the evolutionary relationships among species.

Animal Classification Overview

All animals fall under the Kingdom Animalia.
The Phylum for all animals in animal science is Chordata.
Livestock species primarily belong to the classes Aves (birds) and Mammalia (mammals).

Mammals

Mammals are characterized as chordates that produce milk (lactate).
Protherians are egg-laying mammals, displaying ancestral traits.
Therians consist of mammals that give birth to live young, divided into Metatheria (marsupials) and Eutheria (placental mammals).

Therian Characteristics

Metatherians, like marsupials, have short gestation and give birth to underdeveloped young that continue development in a pouch.
Eutherians keep the embryo in the uterus for longer, leading to more developed young at birth.

Magnorders of Eutherians

Four Magnorders within Eutherians include Xenarthra (from South America), Afrotheria (from Africa), Euarchontoglires (from East Asia), and Laurasiatheria (origin uncertain).

Taxonomical Examples

Human classification: Animalia, Chordata, Mammalia, Primates, Hominidae, Homo, sapiens.
Brown rat classification: Animalia, Chordata, Mammalia, Rodentia, Muridae, Rattus, norvegicus.
House mouse classification: Animalia, Chordata, Mammalia, Rodentia, Muridae, Mus, musculus.
Dog classification: Animalia, Chordata, Mammalia, Carnivora, Canidae, Canis, lupus familiaris.
Cat classification: Animalia, Chordata, Mammalia, Carnivora, Felidae, Felis, silvestris catus.

Other Taxons

Perissodactyla refers to animals with an odd number of toes.
Artiodactyla refers to animals with an even number of toes; both groups include hooved animals (ungulates).
Horse classification: Animalia, Chordata, Mammalia, Perissodactyla, Equidae, Equus, caballus.
Donkey classification: Animalia, Chordata, Mammalia, Perissodactyla, Equidae, Equus, asinus.
Bactrian Camel classification: Animalia, Chordata, Mammalia, Artiodactyla, Camelidae, Camelus, bactrianus.
Llama classification: Animalia, Chordata, Mammalia, Artiodactyla, Camelidae, Lama, glama.
Domestic pig classification: Animalia, Chordata, Mammalia, Artiodactyla, Suidae, Sus, scrofa domestica.
Domesticated species of Cervidae include reindeer.
