Cultural evolution

Unilinear cultural evolution was a 19th-century social theory that posited that all human societies progress along a single, predetermined line of development. This framework suggested that humanity’s history was uniform, with all cultures passing through the same fixed stages of advancement.12
Key characteristics of this theory included:
- Universal Stages: Scholars like Lewis H. Morgan categorized societies into stages such as "savagery," "barbarism," and "civilization," often using technological or subsistence levels as markers.12
- Biological Analogy: Influenced by Charles Darwin, proponents like Herbert Spencer viewed society as an evolving organism that moved from simple, undifferentiated states to complex, specialized civilizations through an increasing division of labour.12
- Western-Centric Progress: The theory assumed that Western society represented the most "advanced" stage, serving as a model for the future of all other populations.2
It is important to note that unilinear cultural evolution is now considered scientifically and ethically flawed. It has been widely criticized for its racist underpinnings, deterministic nature, and lack of empirical support, and it no longer holds credence in modern anthropology or sociology.132
