Evolution was driven by natural selection, to tend to favor organisms that can maximize their energy efficiency. This optimization occurs through various biological adaptations that enhance an organism's ability to obtain, utilize, and conserve energy. Organisms that can obtain more energy from their environment or use energy more efficiently have a competitive advantage, enabling them to survive and reproduce more successfully.
Animals have evolved physiological and behavioral adaptations to conserve energy when necessary, such as hibernation, torpor, or reduced metabolic rates during periods of scarcity. Similarly, the human body has evolved to efficiently allocate energy to essential functions while minimizing waste.
