Title: Are you blue eyed? I am. Post by: sunshine on 09 23, 17, 07:19:21:PM New research shows that all blue-eyed people share a common ancestor. This person lived more than 6,000 years ago and carried a genetic mutation that has now spread across the world.
The exact cause remains to be determined but scientists do know that eye color began to change long before recorded history began. The following is a transcript of the video. All blue-eyed people have one ancestor in common, born around 6,000-10,000 years ago. Blue eyes are caused by a gene mutation. For years, researchers had searched for it on the OCA2 gene. The OCA2 gene determines how much brown pigment is in our eyes. But what they were looking for wasn't there at all. The mutation was found on an entirely different gene called HERC2. HERC2 turns off OCA2, meaning it turns off the brown and reveals the blue. Every blue-eyed person has this exact same mutation. How did this mutation get its start? Possibly when humans migrated from Africa to Europe. This would explain why only people of European descent have blue eyes. It would also suggest that all blue-eyed people share a single European ancestor. Now, that's an impressive family tree! Title: Re: Are you blue eyed? I am.

When I had the lead in the HS play, someone remarked how the young freshman ladies will all fall in love with me as the spotlights reflect a bright blue off my eyes. Dad had blue eyes, but grandpa had grey eyes.

Who couldn't love blue eyes? Title: Re: Are you blue eyed? I am. Post by: luvtimes on 09 24, 17, 03:55:03:AM We all come the same family...we all talked the same language once upon a time...but that tower of
Babel changed the world and made folks different...some with brown eyes some with blue...skin also changed...hair too... No I don't have blue eyes but I can see pretty good except for the floaters that by the way is irritating the heck out of me... Getting that checked soon... Title: Re: Are you blue eyed? I am.

Title: Re: Are you blue eyed? I am. Post by: luvtimes on 09 24, 17, 08:51:03:AM my floaters sometimes give off lightning strikes or blackouts last only a second but hey I don't want to be driving down the street and have black outs.
