For a long time, the origin and evolution of humanity have been plagued by fragmented hypotheses. Traditional evolutionary theories such as brain capacity expansion, tool use, hunting and gathering cannot fully explain why humans have embarked on an evolutionary path completely distinct from all other organisms. Based on the four fundamental laws of thermodynamics, dissipative structure theory and Belousov-Zhabotinsky (B-Z) reaction principle, this paper constructs a unified global evolutionary analytical framework: Human beings are intrinsic users of multiple energy sources. This study verifies that the first law of thermodynamics guarantees sustainable energy input and conservation, while the second law dominates the global trend of entropy increase and disorder. Their game and balance give birth to local entropy-decreasing ordered structures in open systems, forming the underlying logic of life and human evolution. The utilization of fire marks the fundamental transition from biological evolution to assisted evolution, enabling humans to convert uncontrollable natural energy into controllable exogenous energy. Meanwhile, this paper proves that long-term social evolution of human beings strictly follows the periodic rhythm of B-Z reaction, and undergoes critical social structural transitions to drive hierarchical progress of civilization. This theory achieves a logically self-consistent, closed-loop chain covering human origin, evolutionary history and social structural upgrading, with rigorous scientific nature and long-term practical guiding significance.
