Are all people with blue eyes related?

There has been a lingering question, are all people with blue eyes related? The answer is yes in someways, we are not like brother and sister but a distant cousin maybe. Danish researchers have recently concluded that somewhere in between 6,000-10,000 years ago everyone on the earth had brown eyes. The gene for blue eyes came after 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. It didn't really turn it off but rather limits its action to reducing the production of melanin in the iris effectively “diluting” brown eyes to blue. If the OCA2 was completely turned off the production of melanin then we would have no pigment in our eyes, hair and skin, also known as an albino. The OCA2 gene is what controls all pigment in us including hair, skin, and eye color. In the study everyone with blue eyes had this mutation in their OCA2 gene. During the 6,000- 10,000 years ago time period someone had this mutation and passed it on to all of their kids passing it on all the way down to our generation. All people with blue eyes have a single common ancestor, the person who was the first to have the genetic mutation thus originating the blue eye gene.
