Answer :
The domestication of plants is an important milestone in human history, marking the transition from nomadic hunter-gatherer societies to settled agricultural communities. This process involved selecting and breeding plants with desirable traits, such as larger seeds or fruit, and occurred independently in different regions around the world.
Based on archaeological evidence, the domestication of plants primarily occurred between 7000 to 9000 B.C. This is the period when many wild plants began to be cultivated in regions like the Fertile Crescent in the Middle East, as well as parts of Asia and Africa. Wheat and barley are among the earliest crops to be domesticated during this time.
Therefore, the correct answer to the multiple-choice question is option 2: 7000 to 9000 B.C.
The domestication of plants was driven by the need for a stable food supply and enabled the formation of more complex societies. It allowed for the development of permanent settlements, leading to advancements in social structures, economies, and eventually, civilizations as we know them today.
