Human evolution: In the beginning was the plant cell

This essay presents an ontological reinterpretation of human evolution, arguing that the plant cell represents the complete primordial energy system, while the animal cell emerges as a reduced, deficit‑driven derivative. Drawing on cellular energetics, endosymbiosis, photon–electron dynamics, and the historical development of evolutionary theory, the work proposes that consciousness, feeding behavior, and autonomy arise as compensatory patterns following the loss of the chloroplast-based photon principle. The text integrates biological, energetic, and philosophical perspectives to outline a unified model of evolution—from the first light‑driven cells to humans as complex shadow‑systems attempting to reconstruct the lost photon space.
