Final answer:
Historical particularism is a concept in cultural anthropology developed by Franz Boas, which argues that each culture evolves according to its own unique historical path and that cultures interact with one another through the diffusion of material objects, practices, and ideas. This approach rejects the idea of a universal model for cultural change.
Step-by-step explanation:
Historical particularism is a concept in cultural anthropology that was developed by Franz Boas as a critique of unilineal evolutionism. Unilineal evolutionism proposed that all cultures follow a single trajectory toward civilization, while Boas argued that each culture evolves according to its own unique historical path. Boas emphasized the diffusion of material objects, practices, and ideas among cultures, highlighting their constant interaction with one another. This approach rejects the idea of a universal model for cultural change and recognizes the diverse and complex nature of cultural evolution.
