Which of the following sets includes three major seed agriculture hearths identified in historical geography?

• A. Amazon Basin; Sahara Oasis; Australian Outback
• B. Iberian Peninsula; Anatolia; Indochina
• C. Mesoamerica; Andes; Pacific Northwest
• D. Mesopotamia (Fertile Crescent); Nile River Valley; Indus Valley

Answer: (D)

Seed agriculture hearths are the places where people first domesticated plants for farming using seeds, fueling the shift from hunting and gathering to settled agriculture and early civilizations. The three major historical hearths identified in geography are Mesopotamia in the Fertile Crescent, the Nile River Valley, and the Indus Valley. In Mesopotamia, the combination of rich river plains and irrigation allowed early farmers to reliably plant and harvest seed crops, supporting urban growth. The Nile Valley benefited from predictable seasonal floods that renewed soil fertility and sustained crop production along a long, centralized corridor. The Indus Valley developed organized agricultural systems that supported dense populations and complex trade networks across a broad area. This trio is widely recognized as the primary seed-based centers of early agriculture, distinguishing them from other regions listed that do not represent the classic three seed agriculture hearths.
