All blue eyed people share one thing, according to science

It's all down to genetics.

Everyone is different in their appearance and that's what makes every individual beautiful in their own way. It's always interesting to hear how some people have brown, green, hazel, grey or blue eyes and of course, the scientific part to anything always piques our interest. According to Science Daily, it has emerged that everyone who has blue eyes at least has the same relation. Researchers at the University of Copenhagen have collected research which found that there was a genetic mutation up to 10,000 years ago. Reportedly, before this mutation, everyone had brown eyes but in one person eye's, they changed from brown to blue which thus was the beginning of blue-eyed people everywhere. All blue-eyed people are reportedly related to this one ancestor whose eyes changed colour and passed the trait on to descendants to come.
