Final answer:
Culture is an adaptive mechanism that is cumulative and responsible for the evolution of human societies.
Step-by-step explanation:
Culture is most responsible for the evolution of human societies. It is an adaptive mechanism that allows humans to adapt and survive in different environments. Culture is cumulative, meaning that it accumulates and builds upon previous knowledge, beliefs, and attitudes. Through processes of innovation, discovery, and cultural diffusion, cultures evolve and change over time. For example, the deliberate use of fire for cooking and farming are cultural adaptations that better suited humans to their environment.
