Biology genetic mutation

A specific genetic mutation is a gene called OCA2 which is involved in the production of melanin the pigment that gives color to hair, eyes and skin. Blue eyes resulted of ancient genetic 'mutation', scientists believe they have tracked down the cause of the eye color of all blue eyed humans on the planet today. Originally we all had brown eyes said Hans Eiberg from the university of copenhagen. Which to be said that blue eye color must likely orginated from the near east area or northwest part of the black sea region, where the great argriculture migration to the northern part of Europe took place in the neolithic periods about 6-10,000 years ago. The mutation affected a gene called OCA2 and "literally' turned off the ability to produce brown eyes, the mutation in the adjacent gene does not switch off the OCA gene entirely but limit it's action, reducing the production of melanin in the iris of the eye brown eyes to be blue.
