Abstract Living organisms synchronize their biological activities with the earth’s rotation through circadian clock, a molecular mechanism that regulates biology and behavior daily. This synchronization factually maximizes positive (e.g., social interactions, feeding) during safe periods, minimizes exposure to dangers predation, darkness) typically at night. Beyond basic regulation, some behaviors like sleep have an additional layer of homeostatic control, ensuring those essential are fulfilled. While is predominantly governed by secondary regulator, though not well-understood, ensures adherence necessary amounts hints fundamental function beyond simple energy conservation safety. Here we explore regulation across seven Drosophila species diverse ecological niches, revealing while circadian-driven aspects consistent, varies significantly. The findings suggest in Drosophilids, evolved primarily for purposes. more complex, homeostatically regulated functions appear independently species-specific manner, universally conserved. laboratory model may reproduce recapitulate primordial evolution.
