What is the process of "cultural diffusion"?

Cultural diffusion is the process by which cultural traits, ideas, practices, and products spread from one society or social group to another. This can occur through various means such as trade, migration, conquest, or other forms of interaction. When cultures come into contact, they often exchange various elements such as languages, religions, technology, and customs, leading to a blending and sharing of cultural aspects.

The choice indicating the exchange of cultural traits between societies accurately encapsulates this concept, highlighting how cultures influence and shape one another over time. This process is crucial for understanding how societies evolve and how globalization can lead to both cultural enrichment and tension.

In contrast, the other options refer to processes or outcomes that do not encapsulate cultural diffusion. The loss of cultural traditions emphasizes a reduction rather than an exchange of cultural traits, while the development of unique local cultures suggests a focus on insularity rather than interaction. Lastly, the isolation of cultural groups speaks to a lack of interaction, directly opposing the essence of cultural diffusion, which is fundamentally about exchange and blending between different cultures.
