Every Blue Eyed Person on the Planet Is a Descendant of One Single Person

Blue eyed people listen up.

Ever wondered why your eyes are the colour they are? Well wonder no more.

Every blue eyed person is descended from a single European who lived around 6,000 to 10,000 years ago, according to scientists.

How did they work it out? Originally, all humans had brown eyes in various shades until there was a specific mutation that made the change.

The mutation is a gene called HERC2 and it switches off OCA2, the gene that determines how much brown pigment we make.

So that’s why eyes become blue. 

As for being descended from the same person, the evidence for this is because every blue eyed person alive today has this same mutation.
