Which statement best defines cumulative cultural evolution?

• A. Cultures change only due to environmental pressures
• B. Cultures evolve by continuously building on the accumulated skills and knowledge of prior generations
• C. Cultures reset each generation
• D. Cultures are unaffected by prior generations

Answer: (B)

Cumulative cultural evolution is the idea that cultures improve over time by stacking new ideas and skills on top of what previous generations have learned. This means innovations are transmitted through social learning with enough fidelity that each generation can build on what came before, leading to progressively more complex technologies, practices, and knowledge. It’s not just about reacting to the environment or starting from scratch each generation; it’s about maintaining and refining accumulated knowledge across generations. Think of it like a relay where each generation passes on a toolkit, and the next generation uses and improves that toolkit, producing advances that wouldn’t be possible if each generation had to reinvent everything anew. This contrasts with views that cultures reset every generation or are completely unchanged by what came before, which would prevent cumulative improvements.
