If you’re a blue-eyed person, you’re probably already aware that you’re more than a little special.
There aren’t THAT many of us lucky enough to have sparkling baby blues, only around 8 per cent of us have them – but did you know the alleged story behind how you came to have them?
Well, science says if you have blue eyes you may actually be related to other people with blue eyes – very, very distantly of course.
According to IFLScience, around 6,000 to 10,000 years ago one single European developed a single mutation, one which a small percentage of the world today have descended from.
The website went on to explain the now global iris coloration in more scientific terms: “More recently, a mutation to a separate, nearby gene called HERC2 has been identified as the cause of blue eyes.
This alteration switches off OCA2, the gene that determines the amount of the brown pigment melanin that we make. It is thought to have first occurred when humans began to migrate from Africa to Europe, meaning that every person with blue eyes is a descendent of a single early European.”
