Final answer:
Cultural diffusion in the past primarily occurred through travel, while diffusion today is predominantly facilitated by technology.
Step-by-step explanation:
Comparing cultural diffusion in the past to diffusion today, we can observe some key differences. In the past, diffusion often happened through travel, as people physically moved from one place to another, taking their culture with them and interacting with new communities. Cultural diffusion in the past primarily occurred through travel, while diffusion today is predominantly facilitated by technology.
For example, the Silk Road facilitated the exchange of goods and ideas between different civilizations. On the other hand, today, diffusion primarily occurs through technology. The rise of the internet and social media platforms has made it easier for cultures to connect, share, and influence each other across borders. People can now communicate instantly, share information, and engage in cultural practices virtually. This has significantly accelerated the process of cultural diffusion in the modern world.
