Ancient Clock Genes and Earth’s Day

Imagine an Earth where the sun rises and sets every 18 hours instead of 24.

Millions of years ago, that was our reality. As the Earth's rotation gradually slowed

down, living organisms faced massive pressure to adjust to a lengthening day.

This led to a fascinating evolutionary feat: our clock genes actually shifted over millions of

years, altering our molecular cycles to stay in perfect synchrony with the solar day.

This deep-rooted biological need to "rest" at the right time wasn't just a habit—it

was a survival strategy. Today, those same ancient genes are still hard at work,

integrating our need for sleep with the celestial mechanics of the planet. Discover the ancient
