Which concept is primarily concerned with how cultural knowledge accumulates over generations?

• A. methodological equivalence
• B. cumulative cultural evolution
• C. cultural diffusion
• D. linguistic relativity

Answer: (B)

Cumulative cultural evolution refers to how cultural knowledge, practices, and technologies build up over generations as people learn from one another, retain successful innovations, and modify them. This creates a ratcheting effect where small improvements accumulate, leading to increasingly complex or refined culture over time. That’s why it’s the best fit for describing how cultural knowledge accumulates across generations. Cultural diffusion, in contrast, is about the spread of cultural traits between groups, not the generational buildup within a lineage. Linguistic relativity concerns how language shapes thought, not the accumulation of cultural knowledge. Methodological equivalence relates to comparing research methods across cultures, not to how culture accumulates.
