Final answer:
Hyperdiffusionism, an explanatory model in history, was discredited due to its lack of evidence and a clear mechanism that could fit with the understanding of historical processes.
Step-by-step explanation:
Hyperdiffusionism, an explanatory model in history, was ultimately discredited due to its lack of sufficient evidence and a clear mechanism that could fit with the understanding of historical processes. Hyperdiffusionism proposed that cultural and technological developments were primarily spread by a single dominant society, rather than through multiple independent developments. However, further research and analysis revealed that cultural and technological diffusion is a complex process involving various factors, such as trade, migration, and contact between different societies.
