What does cultural diffusion refer to?

Cultural diffusion specifically refers to the process by which cultural beliefs, social activities, and practices spread from one group or society to another. This phenomenon occurs through various means such as trade, migration, or communication, leading to the exchange and blending of ideas, customs, and traditions. The concept emphasizes how cultures influence each other over time, resulting in the enrichment or alteration of practices in both the originating and receiving groups.

In this context, while adaptation of cultural practices (as mentioned in option A) is a separate concept that involves cultures modifying their traditions in response to changes, it does not encompass the broader exchange inherent in cultural diffusion. Similarly, the integration of cultures into a homogeneous society (option C) relates more to a fusion that may occur after diffusion has taken place, rather than the act of diffusion itself. Lastly, the impact of government on cultural expression (option D) is focused on regulatory frameworks and policies affecting culture rather than the foundational process of cultural exchange at its core. Thus, the correct definition of cultural diffusion is reflected accurately in the second option.
