Which term describes cultures evolving through sharing and building knowledge across generations?

• A. orthography
• B. cumulative cultural evolution
• C. cultural diffusion
• D. ethnography

Answer: (B)

Cumulative cultural evolution describes how cultures evolve by sharing knowledge and continually building on what is known across generations. This process happens through social learning, teaching, and imitation, where ideas, tools, and practices are transmitted with enough fidelity to be refined and improved over time. As each generation adds on to what came before, cultures become more complex and capable—for example, advances in pottery, agriculture, or language arise because people not only imitate but also modify and enhance existing techniques. Orthography is about writing systems, which isn’t the process of cultural change over generations. Cultural diffusion refers to the spread of cultural elements between groups, which is about movement rather than the internal accumulation within a lineage. Ethnography is the study of cultures, not the mechanism of how culture evolves across generations. Thus, cumulative cultural evolution is the best fit for describing cultures evolving through shared knowledge across generations.
