Historically, historians believed that the ancient Silk Road was solely a commercial highway for luxury goods like silk and spices. However, recent archaeological findings suggest that its most significant impact was actually the transmission of agricultural technologies.
Initially, excavations revealed that eastern crops, such as rice and peaches, began appearing in western markets much earlier than previously recorded. This discovery challenged the traditional view of the route as a simple merchant path, indicating a deeper ecological exchange. Furthermore, research showed that these crops did not just travel as cargo; instead, farming techniques and irrigation methods were systematically adopted by local communities along the route. Ultimately, this agricultural exchange permanently transformed the diets and farming landscapes of both East Asia and the Mediterranean, establishing the Silk Road as a catalyst for global environmental change rather than a mere trade route.
Based on the passage, what is the correct order of the steps of the author's central argument, from the initial premise to the final conclusion?
- 1The author presents the traditional historical consensus that the Silk Road functioned primarily as a commercial channel for luxury goods.
- 2The author introduces new archaeological findings showing early crop appearances to dispute the commercial-only view.
- 3The author explains that the exchange involved the active adoption of farming and irrigation techniques, not just the transport of goods.
- 4The author concludes that the Silk Road's primary legacy is its role as a driver of permanent, global environmental transformation.
