Animal Science Quiz Bowl Unit 1 Chapter 1

Zoology

The scientific study of the behavior, structure, physiology, classification, and distribution of animals.

Animal Science

A subcategory of zoology that deals specifically with the care, management, and production of animals that live and work with people.

Domestication

The process of changing a wild animal's genetics and behavior over time for the benefit of humans.

5 Requirements for Domestication

1. Structurally different, 2. Behaviorally different, 3. Relies on humans for survival, 4. Reproduction is controlled, 5. Has a clear purpose.

Wild Animals

Animals that live in their natural environment unaltered by human interaction, management, or genetics.

Tame Wild Animals

Wild animals that are taken from nature and cared for by humans, but have not changed behaviorally or structurally from their wild counterparts.

Feral Animals

Animals that belong to a domesticated species but now live in the wild with no human assistance (e.g., feral hogs).

Feral Hog Damage

Escaped swine groups that reproduce in the wild and cause an estimated $1.5 billion in damage each year in the United States.

Dog Domestication Timeline

The first animal to be domesticated, diverging from wolves between 40,000 and 14,000 BCE in East Asia.

Sheep Domestication Timeline

Domesticated around 8500 BCE in Southwest Asia; the first animal domesticated primarily for food.

Pig Domestication Timeline

Domesticated around 7000–6000 BCE in East Asia and China.

Cow Domestication Timeline

Domesticated around 7000–6000 BCE in India, the Middle East, and Sub-Saharan Africa.

Cat Domestication Timeline

Domesticated around 10,000 BCE in the Western Asia and Middle East regions.

Chicken Domestication Timeline

Domesticated around 6000 BCE in India and Southeast Asia.

Horse Domestication Timeline

Domesticated around 3000 BCE in Asia, altering transportation, warfare, and human civilization.

Turkey Domestication Timeline

The most recently domesticated animal used in agricultural production, domesticated around 500 years ago in North America.

Water Buffalo Fact

More people rely on this animal to produce food and transport goods than any other animal across the globe, with over 150 million providing water buffalo service.

Animal Industry

The sector of agriculture that includes all work related to raising animals, processing animal products, and marketing goods/services from animals.

USDA

United States Department of Agriculture; the governmental agency responsible for regulating the animal industry and ensuring safe, healthy conditions.

US Livestock Population: Chickens

By far the largest population group in US agriculture, totaling roughly 10 billion animals.

US Livestock Population: Cattle

The second-largest livestock population group in the US, totaling around 100 million animals.

US Livestock Population: Cats & Dogs

Companion animals with massive economic footprints, totaling 95 million cats and 80 million dogs in the US.

US Livestock Population: Swine, Horses, Sheep

Population sizes in the United States standing at 70 million swine, 9 million horses, and 7 million sheep.

Taxonomy

The scientific classification of organisms used to identify where differences and similarities exist among species.

Carolus Linnaeus

The Swedish botanist who originally developed the seven-level system of biological classification using Latin words.

Hierarchy of Biological Classification

The 7 main levels from broadest to most specific: Kingdom, Phylum, Class, Order, Family, Genus, Species.

Kings Play Chess On Fancy Golden Stools

A common mnemonic device used to remember Linnaeus's hierarchy (Kingdom, Phylum, Class, Order, Family, Genus, Species).

Binomial Nomenclature

The two-word naming system where an animal is identified by its Genus (capitalized) and Species (lowercase), written in italics.

Canis lupus familiaris

The scientific binomial name for the domestic dog.

Equus caballus

The scientific binomial name for the domestic horse.

Bos taurus / Bos indicus

The scientific binomial names for European and Indian breeds of domestic cattle.

Product

Anything refined and sold from an animal for human consumption or use, such as honey, cheese, or leather.

Service

Any type of work or utility completed by an animal for human benefit, such as pulling carts, herding, or companionship.

By-product

Secondary products derived from animals after harvest outside of standard food and fiber, created to utilize as much of the animal as possible (e.g., gelatin, adhesives, medical supplies).

Animal Food Products

Items produced by or harvested from animals for human consumption, including meat, milk, dairy, eggs, and honey.

Animal Fiber Products

Materials collected from animals used for clothing, furniture, and textiles, including leather, wool, mohair, fur, and silk.

Three Categories of Animal Services

Labor, specialized services, and companionship.

Animal Labor

Work done by animals to transport goods and produce crops, especially in areas lacking modern machinery.

Examples of Labor Animals

Water buffalo, donkeys, burros, horses, dogs, caribou, oxen, and elephants.

Specialized Animal Services

Highly trained animals that assist humans with specific safety, medical, or legal tasks (e.g., detecting drugs or tracking survivors).

Examples of Specialized Services

Service dogs for disabilities, drug/explosive detection dogs, search-and-rescue dogs, and animals used in medical research.

Companionship

An important service where animals provide emotional support and friendship to humans as pets.

Health Benefits of Animal Companionship

Studies show pet owners often live longer, report lower stress levels, and experience better overall health.

Recreation Animals

Animals used by humans for entertainment, sport, or leisure, such as in rodeos, horse shows, or movies.
