Final answer:
Several domestic wheat varieties and other crops were first grown in the Fertile Crescent around 8000 BC, a region crucial for the development of agriculture and the rise of civilizations.
Step-by-step explanation:
Several varieties of domestic wheat, along with oats, rye, barley, and lentils were grown after about 8000 BC in the area known as the Fertile Crescent. This region, extending from the Persian Gulf to the eastern Mediterranean, includes Mesopotamia, southern Anatolia, and the Levant, and is recognized for its early evidence of agriculture. The Fertile Crescent is where some of the world's first domesticated crops were cultivated, serving as the birthplace for the agricultural revolution that led to the rise of civilizations.
The domestication of these crop varieties provided a stable food source, which in turn led to the development of settled communities and ultimately the formation of complex societies. With wheat being one of the oldest crop species, originating around 10,000 BC, the Fertile Crescent's influence on the spread of agriculture is of significant historical importance.
