Green eyes, Rare Eye pigmentation In afghanistan and all over the world

Green eyes are especially rare. In humans, the pigmentation of an iris can range from very light amber yellow to a very dark brown, bordering on black. The darkness of the iris depends on its concentration of melanin. The amount of melanin in your eyes or skin determines it’s color. The greater the concentration of melanin, the darker the eye color. Green eyes possess low to moderate amounts of melanin. However, green is actually not a pigmentation of the iris at all.

The main role of skin pigmentation seems to be to absorb ultraviolet radiation and this is true about the iris of the eyes too.

Rayleigh scattering is the dispersion of light off of air molecules, this helps determine eye color. This same scattering of light occurs in the sky which makes it appear blue, orange, pink, etc. and mountains in the distance appear purple or blue. In the eye, this effect occurs in the top layer (stroma) of the iris. The blue optical effect of the Rayleigh scattering combined with the light to medium melanin pigmentation combines to make the eye appear green.

Green eyes In afghanistan

Afghanistan, has been home to those with green eyes for thousands of years. Iran, Pakistan, Central Asia, Russia, Spain, and Brazil all have had populations with green eyes for a long time. All races, including Caucasian, African, Asian, Pacific Islanders, Arabic, Hispanic and the Indigenous Peoples of the Americas can also have green eyes. Green eyes most likely developed because of the migration of people over time, those from northern latitudes with light coloring traveled south and people of dark coloring traveling north intermixed, leading to a variation of melanin produced. Today the green eyes of their descendents is found on every continent.

Notably, there have been records of people with green eyes originating around the Caucasus mountains, which links Europe and Asia. Several passes through the mountain range made it a strategic region or military and trade(silk road).

There is a village in north western China called Liqian in which two-thirds of the inhabitants have green eyes and blonde hair. DNA has linked these people to an ancestor(s) that was caucasian. Some believe that they are descendents of the legendary missing army of Marcus Crassus, a Roman general that disappeared in 36 bc.Liqian is along the silk road trade route so many people passed through.

Is it possible there will be more green eyed people in the future due to mass migration and globalization? For now only time will tell.
