Name two early centers of plant domestication identified in agricultural origins studies.

• A. The Indus Valley and Nile Delta
• B. The Andes and Siberia
• C. The Amazon and Congo Basin
• D. The Fertile Crescent and Yangtze River valley

Answer: (D)

Identifying where plant domestication began shows how agriculture started in different regions. Two of the earliest centers researchers consistently identify are the Fertile Crescent in the Near East and the Yangtze River valley in China. In the Fertile Crescent, archaeobotanical evidence points to early cultivation and domestication of crops like wheat and barley around ten thousand years ago. In the Yangtze River valley, rice domestication appears in early agricultural contexts, marking an independent center of domestication in East Asia. This pairing highlights how multiple regions contributed to the shift to farming, which is why it’s the best answer. Other areas did contribute to later domestication of different crops, but the Fertile Crescent and Yangtze River valley are the classic early centers emphasized in agricultural origins studies.
