Research has shown that a genetic mutation caused the eye color (blue) around 6-10,000 years ago. Blue eyed people only have a small degree of variation in the amount of melanin in their eyes. From this knowledge, researchers have noted that people with blue eyes have to be linked to a similar ancestor. All people with blue eyes would have had to inherited the same switch at exactly the same spot in their DNA. Professor Elberg first implicated the OCA2 gene as being responsible for eye colours. The mutation of blue eyes is neither considered good nor bad- it is a mutation such as hair or freckles. This post is from: https://www.sciencedaily.com/releases/2008/01/080130170343.htm
I found this interesting because I have always wondered why our eye colours are different. I mean it is just like our hair and our features, but it is amazing how we have kind of evolved into a mass of different looking people. Just like the species, we as human beings are each our own!
