How did domesticated mammals contribute to food, transportation, and labor for humans?

Domesticated mammals have been integral to human development, serving as essential sources of food, labor, and transportation throughout history.12

Food and Commodities

Initially, many mammals were domesticated primarily for meat and skin. Over time, selective breeding expanded their utility:2
* Dairy and Fiber: Sheep, goats, and eventually cattle were bred for milk and wool production.2
* Versatility: Even animals used for labor, such as cattle, often provided food or other resources at the end of their working lives.1

Labor and Agriculture

Draft animals, including cattle, horses, donkeys, and water buffalo, revolutionized agriculture by providing muscle power for heavy tasks.1
* Farm Work: They were used to pull plows, thresh grain, and pump water.1
* Efficiency: The use of a harness or yoke allowed humans to transfer animal strength to tasks like hauling logs or clearing land.1

Transportation

Mammals facilitated movement and trade across vast distances.12
* Conveyance: Horses, donkeys, and camels were utilized to pull carts, wagons, and chariots, or to carry loads directly.12
* Logistics: In the 19th century, large teams of animals were common for transporting bulk commodities and heavy machinery.1
