A Unified Framework of Biological Evolution Based on Gravity and Gravitational Center.

Taking gravity as the core perspective, this paper proposes a unified framework for the anti‑gravity evolution of animals, filling a long‑standing research gap in this field, and systematically conducts a complete evolutionary derivation from deuterostomes to humans. The study classifies human instincts into a three‑level hierarchical framework, based on which it constructs a complete evolutionary pathway spanning unicellular organisms, human ancestors, anatomically modern humans, and extending into the future evolution of humanity, including a traceability analysis of the common ancestor of highly intelligent humans on the eve of civilization. This evolutionary framework explicitly addresses two key scientific questions: the reason for the exceptionally rapid evolutionary rate of deuterostomes, and the core driving force underlying deuterostome evolution.
