| Key Idea | Culture originated from one or few major centers and spread worldwide. | Culture traits originated in multiple locations independently and spread through migration & diffusion. | Culture spreads through contact & borrowing rather than migration. |
| Major Proponents | G. Elliot Smith, W.J. Perry | Friedrich Ratzel, Leo Frobenius, Fritz Graebner, Wilhelm Schmidt | Franz Boas, Alfred Kroeber, Clark Wissler |
| View on Cultural Evolution | Strongly opposed evolutionism; argued that cultural traits spread through diffusion. | Rejected unilinear evolution and Tylor’s Psychic Unity of Mankind. Culture is shaped by diffusion & environment. | Criticized the extreme diffusionist approach; focused on regional histories and fieldwork. |
| Methodology | Studied material artifacts & archaeological remains to trace diffusion. | Classified cultures into Culture Circles (Kulturkreis) and studied historical diffusion. | Relied on fieldwork, linguistic studies, and cultural area mapping. |
| Cultural Transmission Mechanism | Large-scale migration of people carried cultural traits. | Cultural traits diffused through overlapping cultural circles rather than one single source. | Traits spread via direct cultural contact (trade, war, intermarriage). |
| Famous Concepts | Heliocentric Diffusion (Egypt as the sole origin of civilization). | Culture Circles (Kulturkreis), Formendedanke (Criteria of Form), Criteria of Quantity. | Culture Area Approach, Age-Area Hypothesis. |
| Examples Used | Argued that pyramids, sun worship, and mummification originated in Egypt and spread globally. | Compared bows, arrows, myths, and social structures to find cultural connections. | Studied Native American cultures, showing cultural diffusion without migration. |
| Criticism | Overemphasized Egyptian influence and ignored independent cultural development. | Failed to explain why diffusion happens; relied on museum-based studies rather than fieldwork. | Ignored cultural universals and focused too much on diffusion instead of innovation. |
