Blue, brown, hazel, green and all of the shades in between—there is one in the list that a small two percent of the population hold. Can you guess what the rarest eye color in the world is?

[4] [35] Hazel eyes often appear to shift in color from a brown to a green. Although hazel mostly consists of brown and green, the dominant color in the eye can either be brown/gold or green.
It may be inherited, or caused by genetic mosaicism, chimerism, disease, or injury. [2] It occurs in humans and certain breeds of domesticated animals. Heterochromia of the eye is called heterochromia iridum or heterochromia iridis. It can be complete, sectoral, or central. In complete heterochromia, one iris is a different color from the other.
Hazel eyes mostly occur in individuals whose ancestry is from North Africa, the Middle East, Brazil and Spain—although, anyone can have this genetic mutation. View the original article to see ...

The Journey of Man: A Genetic Odyssey is a 2002 book by Spencer Wells, an American geneticist and anthropologist, in which he uses techniques and theories of genetics and evolutionary biology to trace the geographical dispersal of early human migrations out of Africa. The book was made into a TV documentary in 2003.
