Answer:
The idea that people, rather than their environment, are the primary forces that shape cultural development is often referred to as "cultural determinism" or "cultural relativism." Cultural determinism emphasizes the role of human agency and individual choices in shaping and creating culture. It suggests that cultural development is primarily driven by human thoughts, beliefs, values, and behaviors, rather than being solely determined by external environmental factors. Cultural relativism, on the other hand, is a related concept that recognizes the diversity of cultures and emphasizes the importance of understanding and evaluating cultural practices within their own cultural context, rather than imposing external judgments or standards.
