Final answer:
The increased interactions between Europe and Asia before 1450 resulted in the spread of new crops westward along trade routes in the Eastern Hemisphere, marking significant agricultural and dietary changes.
Step-by-step explanation:
Based on the interactions between Europe and Asia before 1450, the historical process that also occurred as a result of these increased interactions was the spread of new crops westward along the trade routes in the Eastern Hemisphere. The most decisive evidence for this process can be observed in the transfer of crops such as rice and sugar from Asia to Europe, which had significant effects on both continents' agriculture and diet. This phenomenon is known as the Columbian Exchange, though it began before Columbus' expeditions. Patriarchal customs from China, while influential, were not largely adopted by Europeans to change existing gender relations during this period. The use of slaves for military and domestic purposes did become more widespread, but this was largely a result of interactions with Africa and the explosion of the Atlantic slave trade, which occurred after 1450. European states had not yet begun to conquer and colonize parts of Africa and the Middle East; this would come later during the Age of Exploration starting in the late 15th century.
