Domestication

Domestication is a change that happens in wild animals or plants, when they are kept by humans for a long time.

If humans take wild animals and plants and keep and breed them, over time the animals and plants may change. The animals and plants become dependent on the humans who keep them, and they change in ways that are better for human use. This change (domestication) happens by humans choosing which animals will breed the next generation. This method is called by biologists artificial selection.

The first domestication of plants happened during the first use of agriculture. Human first domesticated dogs. After the invention of agriculture, people domesticated sheep and goats, and later cattle and pigs.

Domesticated plants are crops or ornamental plants. People use domesticated animals as livestock, that means for food, clothing, and work. Otherwise, the domesticated animals may be kept as pets.

Origin of the dog[change | change source]

The origin of the domestic dog (Canis lupus familiaris) began with the domestication of the grey wolf (Canis lupus) several tens of thousands of years ago.[1][2][3] Domesticated dogs provided early humans with a guard animal, a source of food, fur, and a working animal (hunting, pulling sleds). The process continues to this day.

Archaeology has placed the earliest known domestication at possibly 30,000 BC,[1][2] and with certainty at 7,000 BC.[3] Other evidence suggests that dogs were first domesticated in East Asia.[4]

Perhaps the earliest clear cultural evidence for this domestication is the first dog found buried together with human, 12,000 years ago in Palestine.[5][6]

Other animals[change | change source]

Cats were also domesticated quite early.[7][8] At the beginning of agriculture, people started to domesticate sheep and goats, and later pigs and cattle. Other animals that were domesticated early are camels, donkeys and horses. Some animals, like the domestic rabbit, were only domesticated in recent times.

Domesticated plants[change | change source]

The first evidence of plant domestication comes from wheat found in pre-Pottery Neolithic villages in Southwest Asia. They are dated at 10,500 to 10,100 BC.[9] The Fertile Crescent, Egypt, and India were sites of the earliest planned sowing and harvesting of plants.[10]

Agriculture developed independently in a number of places at different times.[9] The eight Neolithic founder crops (emmer wheat, einkorn wheat, barley, peas, lentils, bitter vetch, chickpeas and flax) had all appeared by about 7000 BC.[11]
