The shocking origin of human eyes traces back to an ancient “cyclops”
A 600-million-year-old “cyclops” ancestor helped shape your eyes—and still controls your sleep today.

The Pineal Gland: A Living Remnant of an Ancient Eye

One of the most intriguing discoveries is that a piece of this ancient eye still exists in humans today. It has evolved into the pineal gland, a light-sensitive organ in the brain.

The pineal gland produces melatonin, a hormone that helps control the body's circadian rhythm, including sleep patterns.

"It's mind-boggling that our pineal gland's ability to regulate our sleep according to light stems from the cyclopean median eye of a distant ancestor 600 million years ago," concludes Dan-E Nilsson.
