Scientists trace the shocking origin of human eyes to an ancient “cyclops”

Scientists have discovered that human eyes may have originated from a tiny one-eyed ancestor that lived nearly 600 million years ago. This ancient creature is believed to have played a significant role in shaping the evolution of every vertebrate eye, including those of humans. The researchers also found that the ancestor's median eye has evolved into the pineal gland, which regulates sleep patterns in synchronization with daylight. The pineal gland's function is a lasting legacy of this ancient one-eyed creature.
