"Originally, we all had brown eyes," said Professor Eiberg."But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a 'switch' which literally turned off the ability to produce brown eyes." Variations in the colour of people's eyes can be explained by the amount of melanin in the iris, but blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes, he said."From this we can conclude that all blue-eyed individuals are linked to the same ancestor.They have all inherited the same switch at exactly the same spot in their DNA," said Professor Eiberg.Occasionally, the character themselves will hate their own eyes because it makes them "different." "The eyes are the window to the soul" may be a factor. Be very careful if you want to make that a character trait for one of your own creations.

Everyone with blue eyes alive today – from Angelina Jolie to Wayne Rooney – can trace their ancestry back to one person who probably lived about 10,000 years ago in the Black Sea region, a study has found.He did not have the “lactose-tolerance” genes that allowed him to digest milk as an adult – a key sign that he had little or no contact with domesticated livestock.His well-preserved skeleton was one of two discovered in 2006 in a deep cave system called La Braña-Arintero near León in north-west Spain, which is 1,500m above sea level and cold enough to limit the bacterial decay of DNA.Professor Eiberg said he has analysed the DNA of about 800 people with blue eyes, ranging from fair-skinned, blond-haired Scandinavians to dark-skinned, blue-eyed people living in Turkey and Jordan."All of them, apart from possibly one exception, had exactly the same DNA sequence in the region of the OCA2 gene.
