Quick Summary

Unilineal cultural evolution is a 19th-century concept in anthropology that viewed cultures as progressing through a series of fixed, simple-to-complex stages. This theory suggested that all societies followed a single, universal path of development, with European cultures often seen as the most advanced.123

Key figures like Lewis Henry Morgan proposed specific stages, such as savagery, barbarism, and civilization. However, this unilineal approach fell out of favor in the early 20th century due to criticisms of its ethnocentrism and lack of empirical support. Modern anthropology favors multilinear evolution, recognizing that cultures evolve along diverse paths influenced by unique environmental and historical factors.1234
