Every blue-eyed person on Earth is a descendant of one person!

If you have blue eyes according to science, you are a descendant of one person!

So, according to science, the genetic mutation came from a single human who lived 6,000 to 10,000 years ago.

For years, teams of researchers have worked to uncover the truth behind this development, examining the OCA2 gene that determines the level of brown pigment in the human eye.

But it turns out that the genetic mutation that causes people to develop blue eyes actually comes from a completely different gene, called HERC2. In other words, nature completely inactivates OCA2 thus turning brown into blue.

How do we know that all humans are related to a common ancestor? The reason is that people with blue eyes have the exact same mutation.

“People with green eyes can be explained by the fact that they have a low amount of melanin in the iris, which is completely different from people with blue eyes,” says study author Professor Hans Eberg, writing in Science Daily. “From this we can conclude that all Blue-eyed people are related to the same ancestor. They all inherited the same switch in the exact same place in their DNA.
