Plants:

The first domesticated plants in Mesopotamia were wheat, barley, lentils, and types of peas. People in other parts of the world, including eastern Asia, parts of Africa, and parts of North and South America, also domesticated plants. Other plants that were cultivated by early civilizations included rice (in Asia) and potatoes (in South America).

animals:

Goats were probably the first animals to be domesticated, followed closely by sheep. In Southeast Asia, chickens also were domesticated about 10,000 years ago. Later, people began domesticating larger animals, such as oxen or horses, for plowing and transportation. These are known as beasts of burden.
