Quizplus · Accepted Answer

Professor Morant states that the most potent zeitgeber for land animals, including humans, is light. This is in line with scientific research which has shown that exposure to light - particularly natural daylight - plays a crucial role in regulating our internal body clocks and maintaining normal sleep-wake cycles. The other options listed (tides, temperature, and seasons) can also have some impact on animals' behavior and physiology, but none are as powerful as light in terms of entraining circadian rhythms.
