A type of diffusion where an underlying principle spreads, prompting the invention or innovation of a new trait. It isn’t the direct adoption of a cultural practice, but rather the adoption of its underlying idea. For example, the development of different writing systems after the concept of writing spread from the Middle East demonstrates this. While the idea of written communication diffused, specific writing systems unique to different cultures emerged.
This process is crucial in understanding cultural changes. It illustrates that cultural exchange is not always a simple adoption, but an adaptation and modification of ideas. Examining this helps geographers understand how cultures retain their uniqueness while still being influenced by the world around them. Historically, observing this mechanism helps clarify how innovations take root and evolve within societies.
