Tidal-Thermal Synchronization Theory: Environmental Rhythms as Drivers of Early Life Evolution

The emergence and early evolution of life may have been fundamentally shaped by the synchronization of environmental rhythms. Here, we propose the Tidal- Thermal Synchronization Theory (TTST), which posits that life's basic physio- logical systems emerged through the coupling of high-frequency thermal rhythms from hydrothermal vents with periodic tidal forces from the early Moon. This dual rhythmic system, combined with the solar day-night cycle, created a hierarchical temporal framework that guided the evolution of biological timing mechanisms. We present mathematical models describing this multi-scale environmental forc- ing and demonstrate how these rhythms could have provided templates for the development of fundamental biological systems including circulation and neural os- cillations. The theory o ers new perspectives on the Snowball Earth events and the subsequent Cambrian explosion, suggesting that disruption and restoration of rhythmic coupling may drive major evolutionary transitions. TTST provides a unifying framework for understanding how life internalized cosmic rhythms into its fundamental architecture.
